Definitions

  • the invention relates to a pressing tool, in particular for connecting tubular workpieces, with more than two arcuate pressing jaws which are movable relative to one another in such a way that they can be opened for placement on the workpiece and that they complement one another towards the end of the pressing to form a closed pressing space, and with at least one drive device for moving pressing jaws in the pressing direction.
  • Coupling sleeves are used to connect pipe ends, which are plastically deformable and made of metal, preferably steel. Their inner diameter is so much larger than the outer diameter of the pipe ends to be connected that they are permanently deformed in the event of radial compression until they abut the outer surface of the pipe ends. According to DE-PS 1 187 870 ⁇ , such coupling sleeves can additionally have an annular groove on the inside near each end, into which an elastic sealing ring is inserted.
  • the radial compression takes place by means of pressing tools, as are known for example from DE-PS 21 36 782.
  • This pressing tool has two clamping arms, each with two arms, at least one of which is pivotably mounted on the pressing tool.
  • the press jaws have press surfaces which form circular arc sections and have the same radii and enclose a press chamber.
  • the pressing surfaces can also be contoured instead of as circular arc sections be, for example, to form a polygonal or oval press room.
  • the arms of the press jaws which are distant from the press chamber can be spread against the action of a spring, with the result that the press jaws are moved against one another in the region of the press chamber.
  • the spreading takes place by means of pressure rollers which are arranged next to one another and lie against one another and which are moved together between the arms by means of a drive device in the form of a working cylinder and in this way pivot the press jaws.
  • the clamping jaws When pivoting the drive lever in the opposite direction, the clamping jaws are pivoted again so that the perpendicular to their arc sections approximately collapse and the clamping jaws are moved parallel to each other when the drive lever is pivoted further. During the pressing process, the clamping jaws are moved further towards each other until they enclose a circular area at the end of the press and thereby the pipe ends or the coupling sleeve have deformed accordingly while reducing the diameter.
  • This press tool has proven itself when a not too large reduction in diameter or press-in depth is required. For larger press-in depths, which are required if the pipe connection is to withstand higher internal pressures, it is necessary to provide more than two press jaws so that there is no formation of outwardly projecting webs between the end faces of the press jaws, which leads to a complete closing of the press jaws would prevent.
  • Such pressing tools are described for example in DE-OS 21 18 782, DE-OS 35 13 129, DE-AS 25 11 942 and DE-AS 19 0 197 956. All the pressing tools disclosed therein have in common that all pressing jaws are movable and guided in the radial direction. This requires complex guides and drive devices, making the pressing tools difficult and therefore difficult to handle and also expensive.
  • the invention is therefore based on the object of designing a press tool of the type mentioned in such a way that, despite the arrangement of more than two press jaws, it is as simple as possible and thus easy to handle and can be produced inexpensively.
  • one of the press jaws is designed as an abutment that can be attached to the workpiece and the other press jaws are movable by means of the drive device (s) and are guided in such a way that they each move towards the center during the pressing process move the press room in the closed state of the press tool. It is expedient if the press jaws are guided such that they can move relative to one another in such a way that their respective opposite end faces have the same spacing at the start of the press.
  • the pressing tool according to the invention is characterized by simple structure, since one of the press jaws is designed as an abutment and thus requires neither a guide nor a drive device.
  • the remaining press jaws are guided and driven so that they move in very specific directions during the pressing process, specifically towards the center of the pressing chamber in the closed state of the pressing tool. This is very important for the same forces acting on the workpiece from all sides.
  • the press jaws have circular arc sections of equal length in the circumferential direction, that is to say the gaps between the respective opposite end faces of the press jaws are distributed uniformly over the circumference.
  • the directions of movement of the two movable press jaws should include an angle of 60 °, which is symmetrical to the perpendicular to the abutment and opens away from it.
  • the directions of movement of the two press jaws adjacent to the abutment should include an angle of 90 ° during the pressing process, which lies symmetrically to the perpendicular to the abutment and opens away from it.
  • the abutment is designed as an abutment bracket located at the free end of the pressing tool, which is pivotably mounted on one side and which can be released or locked on the opposite side.
  • This abutment bracket can be pivoted away when the pressing tool is attached to the pipe ends to be connected or to the coupling sleeve. After swiveling back and locking, the movable press jaws can then be moved in the direction of the abutment by means of the drive device.
  • the movable press jaws on the one hand rest against their guide directions and on the other hand on a movable press die in the direction of the abutment, which is connected to the drive device (s) and on which the press jaws adjacent to the abutment are slidably mounted.
  • the press ram is part of the drive device and can be designed, for example, as a hydraulic cylinder or connected to one.
  • a separate drive device can also be provided for each movable press jaw, for example, again a hydraulic cylinder. This can have a press or tension stamp.
  • the abutment is part of a press with press jaws connected in an articulated manner, which is open between two press jaws, the press ring being closable by means of the drive device (s).
  • the drive device (s) can engage at the free ends of the press ring.
  • This embodiment opens up the possibility that the drive device (s) is or are separate from the press ring and the drive device (s) and the press ring have coupling elements, by means of which they can be brought into operative connection with one another.
  • the pressing tool is thus formed in two parts, the pressing ring first being placed around the workpiece and the pressing jaw serving as an abutment being brought into contact, and then the pressing tool being attached to the pressing ring.
  • This embodiment is very advantageous in its handling, since the individual parts have a significantly lower weight and can be handled independently of one another.
  • the press ring can have at least one tension band lying on the outside against at least the movable press jaws, by means of which the pressure jaws can be moved together, wherein two tension bands can also be provided for this purpose.
  • This version is particularly weight and cost-saving.
  • the free ends of the recess (3) are connected by an abutment bracket (4).
  • the abutment bracket (4) is pivotally mounted on its right side in this view about a bearing pin (5). On the left side in this view, the abutment bracket (4) is fixed in the position shown via a locking pin (6).
  • This locking pin (6) passes through corresponding recesses in the tool housing (2) and in the abutment (4) and can be easily removed. After its removal, the abutment bracket (4) can be pivoted around the bearing pin (5) in the directions of the double arrow A, clockwise until the recess (3) is up is fully open.
  • the abutment bracket (4) has a pressing surface (7) which has the shape of a circular arc and extends over an angle of 120 ° symmetrically to the longitudinal axis of the pressing tool (1).
  • the pressing surface (7) has a groove which runs in the circumferential direction and is open inwards. It can be exchangeably attached to the abutment bracket (4).
  • Sloping guide surfaces (8, 9) which enclose an angle of 60 ° and run mirror-symmetrically to the longitudinal axis of the pressing tool (1), run inside the tool housing (2).
  • One press jaw (10 8, 11) each lies on the guide surfaces (8, 9), specifically via correspondingly inclined contact surfaces (12, 13).
  • the pressing jaws (10 ⁇ , 11) are also mirror-symmetrical to the longitudinal axis of the pressing tool (1) and each have a pressing surface (14, 15), each of which is designed as a circular arc section extending over 120 °.
  • a circumferential groove is also formed on the inside.
  • the circular arc sections of all pressing surfaces (7, 14, 15) have identical radii.
  • the pressing jaws (10 ⁇ , 11) protrude on the underside into a guide groove (16) which runs horizontally and transversely to the longitudinal axis of the pressing tool (1) and is formed in the head (17) of a pressing die (18).
  • the undersides of the pressing jaws (10 ⁇ , 11) also run horizontally, so that the pressing jaws (10 ⁇ , 11) are guided in the groove (16) displaceably in the groove (16) transversely to the longitudinal axis of the pressing tool (1), in accordance with Art a dovetail guide.
  • transverse blind holes (19, 20 ⁇ ) are formed, which are coaxial to each other.
  • a compression spring (21) is used, which endeavors to press the press jaws (10 ⁇ , 11) outwards and thus over the contact surfaces (12, 13) to the guide surfaces (8, 9).
  • the press ram (18) is mounted vertically linearly movable in the direction of the longitudinal axis of the pressing tool (1) (double arrow B). It is actuated by a pneumatically or hydraulically actuated working cylinder, which is not shown here.
  • the locking of the abutment bracket (4) is first released using the locking bolt (6), i.e. this locking pin (6) is pulled out and the abutment bracket (4) swiveled clockwise until the fork-shaped opening of the recess (3) is completely free.
  • the press ram (18) is in a downwardly retracted position.
  • the pressing tool (1) can then be attached to a coupling sleeve (22) such that the coupling sleeve (22) extends through the recess (3) perpendicular to the plane of the drawing and is received by the latter.
  • the abutment (4) is pivoted back around the coupling sleeve (22) and locked by inserting the locking bolt (6).
  • the coupling sleeve (22) is then enclosed by the pressing tool (1).
  • the press jaws (10 ⁇ , 11) are then brought into contact with the coupling sleeve (23) by raising the press ram (18). Since their radius is smaller by the intended insertion depth than the radius of the coupling sleeve (22) before pressing, the pressing surfaces (7, 14, 15) only lie with their outer transverse edges on the circumference of the coupling sleeve (22). Between the end faces of the Press jaws (10 ⁇ , 11) and the abutment bracket (4) are still free gaps (23, 24, 25), which are the same size.
  • the radii of the circular arc sections of the pressing surfaces (7, 14, 15) start from centers which lie in the tips of an equilateral triangle.
  • the press ram (18) is then moved upward by further pressurization.
  • the press jaws (10 ⁇ , 11) slide over their contact surfaces (12, 13) over the guide surfaces (8, 9), which means that one in the directions of the double arrows C, D running direction of movement is impressed.
  • the two directions of movement enclose the same angle as the guide surfaces (8, 9), ie 60 °.
  • the press jaws (10 ⁇ , 11) slide simultaneously in the groove (16) of the press ram (18) towards each other, against the action of the compression spring (21). In this way, the coupling sleeve (22) is radially compressed, ie its diameter is reduced by the desired press-in depth.
  • a circular press space is enclosed by the press surfaces (7, 14, 15) and the gaps (23, 24, 25) have been reduced to zero.
  • the press ram (18) is moved back again.
  • the abutment bracket (4) is pivoted away after removing the locking bolt (6) so that the pressing tool (1) can then be removed.
  • a pressing tool (31) is also only partially shown, namely the head area.
  • the pressing tool (31) has a tool housing (32) which is hollow on the inside and which extends downwards for receiving a drive and for the purpose of handling, which is not shown here.
  • Two drive levers (34, 35) are mounted in the tool housing (32) as a mirror image of the longitudinal axis (33) so that they can rotate about pivot bolts (36, 37) extending perpendicular to the plane of the drawing.
  • the downward-pointing arms (38, 39) of the drive lever (34, 35) are spread for pivoting in the directions of the arrows E, F, against the action of a spring (not shown here) which contracts the arms (38, 39) .
  • a pair of pressure rollers is used to spread the arms (38, 39), which can be moved into the space between the arms (38, 39) with the aid of a pneumatically or hydraulically actuated working cylinder.
  • a such drive device is known per se from DE-PS 21 36 782 and DE-OS 34 23 382.
  • Press jaws (42, 43) are received in the arms (40 ⁇ , 41) of the drive lever (34, 35) which extend upwards from the pivot bolts (36, 37).
  • the pressing jaws (42, 43) each have inside pressing surfaces (44, 45) which each form circular arc sections extending over 120 °.
  • Both press jaws (42, 43) are movably mounted on the arms (40 ⁇ , 41) of the drive lever (34, 35) in the circumferential directions according to double arrows G, H. For this purpose, they lie with their outer sides on corresponding circular-arc-shaped guide surfaces (46, 47) in the arms (40 ⁇ , 41), which run coaxially to the circular arc sections of the respective pressing surfaces (44, 45).
  • the press jaws (42, 43) have lugs (48, 49) projecting laterally outwards, on both sides of the guide surfaces (46, 47).
  • the lugs (48, 49) carry guide projections (50 ⁇ , 51) which form-fit into the scenes (52, 53) which are molded into the inside of the tool housing (32). In this way, the pressing jaws (42, 43) are positively guided in the circumferential directions G, H when the drive lever (34, 35) pivots.
  • Another press jaw is formed by an abutment (54) which is arranged in a stationary manner within the tool housing (32) and has a pressing surface (55) on the top, which is designed as a circular arc section extending over 120 °.
  • the circular arc section has the same radius as that of the other pressing surfaces (44, 45).
  • the arms (38, 39) of the drive lever (34, 35) are first pressed together by hand, that is, contrary to the arrows E, F.
  • the arms (40 ⁇ , 41) mouth-like and give a space between the end faces of the press jaws (42, 43) so that the press tool (31) can be pushed across a coupling sleeve (56) transversely to its longitudinal axis.
  • the pressing jaws (42, 43) can be closed. This is done by spreading the lower arms (38, 39) of the drive lever (34, 35) with the help of the drive device, not shown.
  • the press jaws (42, 43) then come to rest on the jacket of the coupling sleeve (56). Since the radii of the pressing surfaces (44, 45, 55) are smaller than the radius of the coupling sleeve (56) before the pressing by the intended insertion depth, the pressing surfaces (44, 45, 55) lie only with their outer transverse edges on the circumference of the coupling sleeve (56).
  • the scenes (52, 53) are shaped such that the pressing jaws (42, 43) in the circumferential direction relative to the arms (40 ⁇ , 41) of the drive lever (34, 45) are shifted accordingly, ie the left press jaw (42) clockwise and the right press jaw (43) counterclockwise.
  • the radii of the circular arc sections of the pressing surfaces (44, 45, 55) start from centers which lie in the tips of an equilateral triangle.
  • the lower arms (38, 39) of the drive lever (34, 35) are additionally spread.
  • the pressing jaws (42, 43) are moved further inwards, the two directions of movement essentially enclosing an angle of 60 °, which is symmetrical to the longitudinal axis (33) and opens away from the abutment (54).
  • the pivot pins (36, 37) each lie on straight lines which start from the center point of the circular arc section of the abutment (54) and form an angle which is twice as large as that of the directions of movement of the press jaws (42, 43) included angles, namely 120 °.
  • the scenes (52, 53) bend afterwards downwards in such a way that the pressing jaws (42, 43) are displaced in the circumferential direction relative to the arms (40 ⁇ , 41), namely the left pressing jaw (42) counterclockwise and the right pressing jaw (43) clockwise.
  • the guide in the scenes (52, 53) is such that the gaps (57, 58, 59) remain the same throughout the pressing process until the end faces of the press jaws (42, 43) and the abutment (54) at the end of the press Plant come.
  • the coupling sleeve (56) is compressed radially and its diameter is reduced by the desired press-in depth.
  • the lower arms (38, 39) of the drive lever (34, 35) are pushed together again, so that the upper arms (40 ⁇ , 41) open like a mouth.
  • the pressing tool (31) can then be removed from the coupling sleeve (56).
  • a pressing tool (61) - also only partially - is shown, this pressing tool (61) being very similar to the pressing tool (31) shown in Figures (3) and (4). It has an internally hollow tool housing (62) which extends downwards for receiving a drive and for the purpose of handling, which is not shown here.
  • Two drive levers (64, 65) are mounted in the tool housing (62) as a mirror image of the longitudinal axis (63) so that they can rotate about pivot bolts (66, 67) extending perpendicular to the plane of the drawing.
  • the downward-pointing arms (68, 69) of the drive levers (64, 65) are spread for pivoting in the directions of arrows I, J, against the action of a lower arm, not shown here (68, 69) contracting spring.
  • a pair of pressure rollers is used to spread the arms (68, 69), as has already been described for the pressing tool (31) in FIGS. (3) and (4).
  • Press jaws (72, 73) are received in the arms (70 ⁇ , 71) of the drive levers (64, 65) which extend upwards from the pivot bolts (66, 67). They each have inside pressing surfaces (74, 75) which each form circular sections extending over 120 °. Both press jaws (72, 73) are movably mounted on the upper arms (70 ⁇ , 71) of the drive lever (64, 65) in the circumferential directions according to the double arrows K, L. For this purpose, you lie with your outer sides on corresponding, circular arc-shaped guide surfaces (76, 77) in the arms (70 ⁇ , 71), which run coaxially to the circular arc sections of the respective pressing surfaces (74, 75).
  • the pressing jaws (72, 73) have notches (78, 79) on their outer circumferences, into which pins (80 ⁇ , 81) which are axially displaceably mounted in the upper arms (70 ⁇ , 71). These pins (80 ⁇ , 81) are spring-loaded via compression springs (82, 83) in the direction of the notches (78, 79).
  • the pins (80 ⁇ , 81) and the notches (78, 79) are arranged so that the pins (80 ⁇ , 81) strive to move the press jaws (72, 73) against each other in the circumferential direction, i.e. the left press jaw (74 ) clockwise and the right press jaw (73) counterclockwise.
  • Stops not shown here ensure that the press jaws (72, 73) cannot be moved beyond these to a certain maximum extent in these two directions.
  • the guidance of the press jaws (72, 73) is such that they do not fall inwards from the receptacles of the arms (70 ⁇ , 71), i.e. a corresponding forced operation is provided.
  • Another press jaw is formed by an abutment (84) which is arranged in a stationary manner within the tool housing (62) and on the top side has a pressing surface (85) which is designed as a circular arc section extending over 120 °.
  • the circular arc section has the same radius as that of the other pressing surfaces (74, 75).
  • the lower arms (68, 69) of the drive lever (64, 65) are first pressed together by hand, that is, contrary to the arrows I, J. This opens the upper arms (70 ⁇ , 71) mouth-like and give space between the end faces of the press jaws (72, 73) so that the press tool (61) can be pushed transversely to its longitudinal axis via a coupling sleeve (86). After the coupling sleeve (86) has been placed on the pressing surface (85) of the abutment (84), the pressing jaws (72, 73) can be closed by spreading the lower arms (68, 69) with the aid of the drive device (not shown here).
  • the press jaws (72, 73) then come to rest on the jacket of the coupling sleeve (86). Since the radii of the pressing surfaces (74, 75, 85) are smaller than the radius of the coupling sleeve (86) before the pressing by the intended insertion depth, the pressing surfaces (74, 75, 85) lie only with their outer transverse edges on the circumference of the coupling sleeve (86).
  • the stops for limiting the movement of the pressing jaws (72, 73) are arranged correspondingly in the circumferential direction.
  • the radii of the circular arc sections of the pressing surfaces (74, 75, 85) start from centers which lie in the tips of an equilateral triangle.
  • the pressing jaws (72, 73) move automatically in the circumferential direction relative to the upper arms (70 ⁇ , 71), namely the left pressing jaw (72) counterclockwise and the right pressing jaw (73) clockwise. It has been shown that the gaps (87, 88, 89) remain essentially the same in this embodiment despite the inaccurate guidance during the entire pressing process until the end faces of the pressing jaws (72, 73) and the abutment (84) on Press end come to rest, as can be seen in Figure (6).
  • the coupling sleeve (86) is compressed radially and its diameter is reduced by the desired press-in depth.
  • pressing tools (91, 92) are shown, each in half.
  • the pressing tool (91) is shown on the left half of the figures (7) and (8) with respect to the axis of symmetry and the pressing tool (92) is shown on the right half.
  • Both pressing tools (91, 92) are mirror-symmetrical, so that their structure results from the representation of their halves.
  • the pressing tool (91) shown in the left halves of the figures (7) and (8) has a pressing ring (93) which consists of a total of three pressing jaws (94, 95), the pressing jaw (94) only because of the half-sided representation partially and a press jaw - namely the right one - cannot be seen at all.
  • a flexible drawstring (97) made of spring steel is fastened to the upper press jaw (94) by means of a screw (96) and extends over the circumference of the upper press jaw (94). and the left press jaw (95) extends.
  • a corresponding tension band runs to the other side of the press ring (93), not shown here.
  • the lower press jaws (95) are displaceable in the circumferential direction K on the tension bands (97).
  • a rubber spring (98) surrounds in recesses in the opposite end faces of the press jaws (94, 95) and is vulcanized onto them.
  • the press jaws (94, 95) are pushed apart by the rubber springs (98) by a certain amount, so that there are gaps (99, 10 ⁇ 0 ⁇ ) of the same width between the opposite end faces of the press jaws (94, 95) when the press jaws (94, 95) rest on the outside on a coupling sleeve (10 ⁇ 1).
  • Coupling lugs (10b or2) are attached to the outside of the free ends of the drawstrings (97).
  • a drive device (10 ⁇ 3) which is only shown schematically and in broken lines here, can be attached to these coupling attachments (10 ⁇ 2) and is separated from the press ring (93).
  • the pressing tool (91) thus consists of two independent parts that can be coupled together.
  • the drive device (10 ⁇ 3) has two drive levers (10 ⁇ 4), of which only the left one can be seen here. They are rotatably mounted about pivot bolts (10 ⁇ 5) extending perpendicular to the plane of the drawing. Your downward-pointing arms (10 ⁇ 6) are spread for pivoting in the direction of arrow L, against the action of a spring, not shown here, which contracts the lower arms (10 ⁇ 6). A pair of pressure rollers is used to spread the arms (10 ⁇ 6), as has already been described for the pressing tool (31) in Figures (3) and (4).
  • the arms (10 ⁇ 7) extending upwards from the pivot bolts (10 ⁇ 5) are shaped in such a way that they can reach behind the coupling projections (10 ⁇ 2).
  • the pressing ring (93) When using the pressing tool (91), the pressing ring (93) is first opened, so that the lower pressing jaws (95) protrude outwards, as shown in broken lines. The press ring (93) can then be pushed across the combination of coupling sleeve (10 ⁇ 1) and pipe end (10 ⁇ 8) transversely to its longitudinal axis. Due to the spring action of the drawstrings (97), the press jaws (94, 95) rest on the circumference of the coupling sleeve (10 ⁇ 1), even here only with the outer transverse edges. Then the drive device (10 ⁇ 3) is set in such a way that the upper arms (10 ⁇ 7) of the drive lever (10 ⁇ 4) grasp the coupling attachments (10 ⁇ 2) on the outside, as can be seen from FIG. (7).
  • the press tool (92) is functionally similar to the press tool (91). It also has a press ring (10 ⁇ 9), which has three press jaws (110 ⁇ , 111) of the same arc length.
  • the upper press jaw (110 ⁇ ) is fixedly arranged on a press jaw support (112), while the two lower press jaws (111) are displaceably guided in the circumferential direction on the press jaw supports (113).
  • the lower press jaw carriers (113) are articulated on the upper press jaw carriers (112) via swivel joints (114).
  • the lower press jaws (111) have notches (115) on their outer circumferences, into which pins (116), which are axially displaceably mounted, engage in the lower press jaw carriers (113). These pins (116) are spring-loaded via compression springs (117) in the direction of the notches (115).
  • the pins (116) and the notches (115) are arranged so that the pins (116) endeavor to move the lower press jaws (111) against each other in the circumferential direction, i.e. the right lower press jaw (111) shown clockwise and the Press jaw, not shown here, counterclockwise. Stops not shown here ensure that the lower press jaws (113) cannot be moved further in these two directions beyond a certain maximum dimension.
  • drive bolts (118) are arranged perpendicular to the plane of the drawing, which take over the function of the coupling lugs (10-2) in the pressing tool (91).
  • the drive device (10 ⁇ 3) shown in the left half of the figures (7) and (8) can be attached to these drive bolts (118) by placing the upper arms (10 ⁇ 7) of the drive levers (10 ⁇ 4) on the outer sides of the drive bolts (118) will.
  • the pressing tool (92) is handled in the same way as the pressing tool (91).
  • the press ring (10 ⁇ 9) is pushed over the coupling sleeve (10 ⁇ 1) and the pipe end (10 ⁇ 8) transversely to its longitudinal axis, the two lower press jaw carriers (113) being opened, i.e. H. are pivoted outwards, as is indicated by dash-dotted lines.
  • the lower press jaw carriers (113) are then brought into contact with the outer circumference of the coupling sleeve (10 ⁇ 1).
  • the abovementioned stops for limiting the movement of the lower press jaws (111) in the circumferential direction are arranged in such a way that gaps (119, 120 ⁇ ) of the same size between the end faces of the press jaws (110 ⁇ , 111) result when the coupling sleeve (10 Kupplungs1) is in contact.
  • the lower press jaws (113) By further spreading the lower arms (10 ⁇ 6) of the drive lever (10 ⁇ 4), the lower press jaws (113) are pivoted inwards, the lower press jaws (111) automatically move in the circumferential direction M, namely the right press jaw (111) shown counterclockwise and the left press jaw, not shown here, clockwise. This continues until the end faces of the press jaws (110 ⁇ , 111) come to rest at the end of the press. This state can be seen in the right half of the figure (8).
  • the pressing tool (92) differs kinematically and therefore in principle not from the pressing tool according to the figures (5) and (6) and also from the pressing tool (31) according to the figures (3) and (4), because even with these pressing tools ( 61, 31) the pressing movement of the pressing jaws (72, 73) or (42, 43) could be brought about by the fact that the upper arms (70 ⁇ , 71) or (40 ⁇ , 41) of the drive levers (64, 65 ) or (34, 35) in the area of the upper column (87) or (57) can be contracted by attaching a suitably designed, separate drive device. In this case, the lower arms (68, 69) or (38, 39) of the drive lever (64, 65) or (34, 35) could be dispensed with.
  • the pressing tools (91, 92) can also be formed in one piece, i. H. the drive device (10 ⁇ 3) can be connected to one of the press jaws (94, 95, 110 ⁇ , 111) via a corresponding housing part.
  • this press jaw (94, 95, 110 ⁇ , 111) would be comparable to the abutments (4, 54, 84) in the exemplary embodiments according to the figures (1) to (6).
  • One of the lower pressing jaws (95, 111) can also be the pressing jaw (95, 111) which is arranged in a fixed position on the pressing tool (91, 92) and performs the function of the abutment. In this case, only one drive lever (10 ⁇ 4) is required to pull the press jaws (94, 95, 110 ⁇ , 111) together.
