Definitions

  • the invention relates to a device head of a hydraulically actuated tool according to the features of the preamble of claim 1.
  • Device heads of the type in question are known in different designs. In conjunction with a hydraulic drive, these are used, for example, for pressing, cutting or punching workpieces, for which corresponding first and second tools must be arranged in the device head or on the hydraulic piston. For example, it will be on the EP1084798 B1 ( US 6,718,870 B1 ) referred.
  • the invention is concerned with the task of developing a device head of the type mentioned specify in which the second tool carrier is advantageously designed with regard to guidance and removal.
  • the second tool carrier is designed to be essentially elongated rectangular with respect to a cross section transverse to a hydraulic piston axis, that in the state of use vertical longitudinal edge edges are designed to be elongated, rectilinear, while transversely shorter edge edges considered for this purpose are each guided along an arcuate line, and that this arcuate line has a common radius relating to the axis, a radius dimension being adapted to a diameter dimension of a surrounding jacket wall of the cylindrical design.
  • the working end position does not necessarily have to be the maximum achievable end position of the hydraulic piston, which may have a limited stop. Rather, the working end position can be the displacement position of the hydraulic piston, in which a measure to be carried out is carried out using the tools according to specifications. From this reached working end position, the hydraulic piston can move back towards the starting position, if necessary automatically as a result of a valve opening in the hydraulic system.
  • the receptacle for the second tool is made in one piece with the piston skirt and more preferably made of the same material as the piston skirt. This offers further advantages in terms of manufacturing and assembly technology.
  • the hydraulic piston can, as further preferred, be provided unconnected to the piston shaft or, alternatively, detachably connected to the piston shaft.
  • the piston shaft is protected from direct damage from the outside, for example when changing the device head or when storing the device head.
  • the device head can also have a toothing formation in one piece for the angularly fixed but changeable arrangement of a holding rod.
  • a mounting rod allows the user to use the device head away from the body.
  • the device head can be stabilized in a working position using the mounting rod.
  • the mounting rod can be used to make it possible to work overhead, at least at a distance of, for example, 1 meter or more.
  • the device head, but possibly also the hydraulic unit acting on the hydraulic cylinder is no longer held directly or solely by hand, but rather, at least additionally, via the holding rod.
  • the holding rod can have a fixed length of, for example, 0.5 meters, 1 meter, 2 meters up to, for example, 3 meters, although any intermediate dimension, for example between 0.5 and 3 meters, can also be given as a fixed length.
  • the holding rod can also be designed to be adjustable in terms of its length in a possible embodiment, for example according to a telescopic design, for example with a telescopic length of 0.5 to 2 meters.
  • Handling via the holding rod is favored due to the intended outer toothing on the device head.
  • This enables an angular, fixed arrangement of the mounting rod relative to a longitudinal central axis of the device head, which longitudinal central axis can optionally also accommodate the axis of rotation of the hydraulic cylinder or the hydraulic piston.
  • This angular arrangement of the holding rod is preferably changeable, for which purpose a positive connection provided via the toothing formation can be temporarily canceled.
  • the integral, one-piece toothing formation can have toothing projections that are raised relative to the surrounding surface of the device head, possibly only one such toothing projection, or alternatively, toothing recesses that recess relative to the above-described surface of the device head, possibly only one toothing recess.
  • the second tool can be moved by means of the hydraulic piston between a starting position and a working end position, the piston shaft having a receptacle which is enlarged transversely to a direction of movement of the hydraulic piston relative to the piston shaft and is assigned to the second tool, and the receptacle in the working end position transversely to the direction of movement is held in an undercut formed on the device head.
  • the receptacle which can be moved in the direction of movement with the piston shaft, is used to hold the second tool, preferably for holding it an interchangeable second tool.
  • This receptacle extends at least in a direction transverse to the direction of movement beyond the lateral surface of the piston skirt, in which case the enlargement of the receptacle relative to the piston skirt can be given at least over a portion of the circumference of the piston skirt viewed with reference to a longitudinal axis of the piston skirt.
  • essentially diametrically opposite enlargement sections can form the receptacle for the second tool.
  • the receptacle can also extend, for example, over the entire circumference of the piston skirt beyond its lateral surface.
  • this receptacle for the second tool In particular, relatively large forces act on this receptacle for the second tool, particularly in the end working position, but also possibly in intermediate positions between the starting position and the end working position.
  • the holder In order to counteract a possible tilting of the holder with the second tool, the holder is held in an undercut.
  • This undercut preferably acts in a direction transverse to the direction of movement of the holder for the second tool. This advantageously makes it possible to achieve an improved work result, for example pressing or cutting results.
  • the receptacle can, for example, have a projection area which is overlapped by an overlapping section of the device head in a direction transverse to the direction of movement of the receptacle.
  • the receptacle can also have a lower gripping section and the device head can have a projection area that interacts in this way.
  • the toothing formation When viewed in a longitudinal cross section of the device head, in which longitudinal cross section a rotation axis of the hydraulic piston appears as a line, the toothing formation can be laterally offset, but designed to overlap the cylindrical design.
  • the overlap can occur in the radial direction with respect to the hydraulic piston axis. This overlap can also occur in a piston shaft area, possibly both in an initial position and in a working end position of the hydraulic piston.
  • the cylindrical design can correspondingly merge in the area of the toothing formation into a leg that is reduced in thickness compared to the diameter of the cylindrical design and is formed integrally and in one piece with the cylindrical design.
  • This leg can also carry the counterholder in an extension essentially in the same direction as the hydraulic piston axis.
  • the toothing formation can be designed to be concentrically circumferential with respect to a central through opening, for example for the passage of a clamping device, for example a clamping screw. If several toothing projections or toothing recesses are provided in the toothing formation, these are preferably positioned in an overall circular or circular section shape with respect to the geometric central axis of the through opening.
  • toothing projections or toothing recesses When arranging several toothing projections or toothing recesses in the toothing formation, these can be provided evenly spaced apart from one another in the circumferential direction, based on the geometric central axis of the through opening.
  • the receptacle for the second tool is made in one piece with the piston shaft, on which the hydraulic piston can preferably act, and more preferably made of the same material.
  • the hydraulic piston can, as further preferred, be provided unconnected to the piston shaft or, alternatively, detachably connected to the piston shaft.
  • the receptacle can be inserted into the device head together with the piston shaft in a one-piece design during assembly or removed from the device head during disassembly.
  • the receptacle in the starting position which can preferably correspond to a basic position of the device head unloaded by the hydraulic piston, can be moved transversely to the direction of movement for assembly and disassembly.
  • This can be achieved in particular by the fact that, at least in this starting position, the undercut with the device head, which is preferably provided in the working end position, is not provided or can be overcome.
  • this undercut and the resulting guidance as well as the anti-twist and tilt protection are only achieved when the receptacle is moved from the starting position towards the end working position.
  • the displaceability of the receptacle in a direction transverse to the direction of movement which is thereby made possible, enables a favorable assembly or disassembly, in particular of a receptacle formed in one piece with the piston shaft, in which it can be tilted into the cylindrical design during assembly or at a Disassembly can be carried out from the cylindrical training.
  • the device head can be connected to a hydraulic hose, which can be connected at the other end to the hydraulic unit in order to allow the device head to move freely relative to a hydraulic unit that generates hydraulic pressure.
  • the hydraulic hose can have a length that allows the device head to move approximately freely while the hydraulic unit is placed, as preferred, on a floor or, for example, at table height.
  • the arrangement of the mounting rod is particularly useful in such a configuration. This configuration allows, for example, overhead use of the device head, and in particular use that should take place at a distance of, for example, one to two meters or more from the user.
  • the device head can also be rigidly connected to a body tool part in which the hydraulic unit is arranged.
  • a fuselage tool part is, for example, from EP 1519813 B1 ( US 7,254,982 B2 ) known.
  • EP 1519813 B1 US 7,254,982 B2
  • the content of this patent specification is hereby fully incorporated into the disclosure of the present invention, also for the purpose of including features of this patent in claims of the present invention.
  • the body tool part can also be used by the user as a handle to guide the device head.
  • the arrangement of the holding rod or the use of an arranged holding rod on the device head can be omitted when the body tool part is arranged.
  • the hydraulic piston can be completely accommodated in the cylindrical design in the starting position.
  • the hydraulic piston or parts of the hydraulic piston preferably do not protrude in the axial direction beyond the cylindrical configuration, possibly the hydraulic cylinder formed thereby. This offers advantages, for example, with a device head that is not connected to a hydraulic hose or a body tool part, for example when changing the device head or storing the device head. Damage to the hydraulic piston or parts of the hydraulic piston due to free protruding beyond the end of the cylindrical design is counteracted by the design according to the invention.
  • the cylindrical design can also be based on the starting position of the hydraulic piston in continuation of a direction of movement of the Hydraulic piston from the working end position to the starting position or in the extension direction of a hydraulic piston rotation axis outside the area surrounding the hydraulic piston have a connection receptacle for the body tool part or the hydraulic hose.
  • the connection receptacle is correspondingly spaced from the hydraulic piston in the axial direction or direction of movement of the hydraulic piston, preferably both in the starting position and in the working end position as well as in every position between these two end positions. This can enable further assembly advantages.

  • the hydraulic piston can consist of a piston shaft and a cover part arranged on the end facing away from the second tool.
  • the piston shaft can be surrounded by a return spring, which is located in the area of one end on the cover part can support.
  • the end of the spring facing away from the cover part is supported on a section of the cylindrical design of the device head.
  • the piston skirt can also be designed as a hollow cylinder over part of its length, for example over 50 to 95% of the length, possibly even over the entire length. This initially achieves a weight reduction in the area of the piston skirt.

  • the clamping screw can hold the cover part while enforcing the hollow cylinder.
  • the clamping screw can interact at the end with a threaded hole, which can be formed in the piston shaft or in a tool holder adjoining the piston shaft for receiving the second tool.

  • an internal thread can be formed on the inside of the connecting receptacle 39 for cooperation with an external thread of the adapter part 40 in the area of its circumferential adapter part wall 41.
  • the adapter part wall 41 can also, as is also preferred, have a seal inserted in a groove on the outside of the wall and open radially outwards 42, which acts against the inner wall 30 of the cylindrical formation 4 or the connection receptacle 39.
  • An adapter base 43 aligned transversely to the axis x leaves an inflow opening 44 for a hydraulic medium in the middle, correspondingly penetrated centrally by the geometric axis x.
  • This inflow opening 44 is surrounded on the outside or away from the hydraulic piston 6 by a stump-like adapter part connection 45.
  • the surface of the adapter base 43 facing away from the hydraulic piston 6 can essentially be aligned with the associated end face of the cylindrical design 4.
  • the adapter part 40 can be fixed in the position of use screwed into the connection receptacle 39 by a set screw 46 passing through the wall of the connection receptacle 39.
  • the device head 1 can according to in Figures 1 to 8
  • the first application shown can be operated via a separate hydraulic unit 47, whereby A hydraulic hose 48 is arranged between the hydraulic unit 47 and the device head 1 for free movement of the device head 1.
  • the hydraulic hose 48 is connected at one end to the hydraulic unit 47 and at the other end via a hose connection 58 to the device head 1 via the adapter part 40 in a sealed manner.
  • a corresponding hydraulic pressure is generated via the hydraulic unit 47.
  • the adapter part 40 can also be used for this purpose, if necessary using the same adapter part 40 as this one for connecting a hydraulic hose 48 but alternatively there is also an adapter part 40 provided separately for the fuselage tool part 49.
  • the body tool part 49 can be essentially elongated, rod-shaped, which basically supports one-handed operation of the device.
  • a possible arrangement of the mounting rod 9 can provide further support in the area of the device head 1.
  • the tool W which is composed of the body tool part 49 and the device head 1, can also be used alone without a holding rod 9, which is why the holding rod 9 is only optionally shown in a dash-dotted line in the illustrations of the second embodiment.
  • the tool-free arrangement of the holding rod 9 via the fixing screw 37 offers such an optional arrangement.
  • a rod-shaped body tool part 49 is from the one cited at the beginning EP 1519813B1 known.
  • the content of this patent is hereby fully incorporated into the disclosure of the present invention, also for the purpose of including features of this patent in the claims of the present invention.
  • the body tool part 49 has a grip area 56 for the usual gripping of the tool part housing with one hand.
  • An operating button 57 is assigned to the handle area 56 in an ergonomically favorable manner.
  • the Figures 12 to 16 show a second embodiment of the device head 1, which differs from the previously described embodiment in particular with regard to the cylindrical design 4 and a guide of the receptacle A or the second tool carrier 12 on the device head 1.
  • the basic mode of operation and operation as well as the basic structure for the hydraulic action on the receptacle A essentially corresponds to the first embodiment described above.
  • the receptacle A or the second tool carrier 12 is preferably formed in one piece and more preferably made of the same material as the piston shaft 13.
  • the cylindrical design 4 extends from the adapter base 43 only to approximately the rear surface 60 facing away from the end face 59 of the receptacle A in the step-like transition from the piston skirt 13 into the receptacle A.
  • the Recording A or the second tool carrier 12 (possibly with the second tool 5) between the facing end faces the cylindrical design 4 and the counterholder 2 except for the area of bottom support and guidance in the area of the connecting leg 10.
  • the receptacle A or the second tool carrier 12 can have a cross-section according to the bottom side, ie facing the connecting leg 10 of the device head 1 Figure 14 essentially T-shaped guide projection 61.
  • the guide projection 61 can be guided in a guide groove 62 of the connecting leg 10 directed in the direction of movement d.
  • the T-head 67 of the guide projection 61 can be arranged facing the groove bottom of the guide groove 62.
  • the T-head 67 of the guide projection can have a cross section corresponding to this Figure 14 waisted T-bar 68 can be connected to the second tool carrier 12.
  • the receptacle A or the second tool carrier 12 is initially secured against rotation about the axis x, and there is also linear guidance of the receptacle A when it is displaced in the direction of movement d.
  • the guide groove 62 of the device head 1 can be partially formed as an undercut 63 acting transversely to the direction of movement d over the length 1 viewed in the direction of movement d.
  • This undercut 63 can be given, for example, by a cross section according to Figure 5 oppositely arranged, mutually directed ribs 64, which are formed at a distance from the groove bottom 69 and are suitable for the waisted area of the guide projection 61 to intervene between the T-head 67 and the receptacle A.
  • the undercut 63 can, for example, extend over approximately half the length l of the guide groove 62 in the direction of movement d, up to approximately 2/3 or 3/4 of this entire length l. It is further preferably provided that this undercut section extends in particular over the usual travel path of the receptacle A, correspondingly over the last half of the travel path up to the last 3/4 of the travel path, so that in particular in the critical force-loaded displacement situation of the receptacle A appropriate guidance and protection against a displacement of the receptacle A in a transverse direction to the direction of movement d is provided.
  • the guide groove 62 is preferably not provided with ribs 64, so that in this area there is no undercut that interacts with the receptacle A (compare in particular the sectional view in Figure 14 ).
  • This offers the advantage of a favorable assembly and disassembly of the receptacle A, which is formed in one piece with the piston skirt 13, while the receptacle A is secured against rotation and tilting in the course of, for example, a pressing or cutting process.
  • Figure 16 shows such an assembly or disassembly position of the receptacle A, which is formed in one piece with the piston skirt 13, or of the second Tool carrier 12.
  • the adapter base 43 with its seal 42 and the piston base 26 with its seal 29 can first be removed from the hydraulic cylinder 7, after which the clamping screw 21 is exposed for loosening it. After removing the clamping screw 21, the cover part 20 and the spring 18 can be removed. The piston shaft 13 then lies alone and freely in the hydraulic cylinder 7.
  • the receptacle A or the second tool carrier 12 can then be offset in a direction transverse to the direction of movement d (see arrow e), so that the guide projection 61 can leave the guide groove 62.
  • This lifting or tilting movement in the direction of arrow e can be directly superimposed with an extension direction f (essentially in the axial direction of the piston shaft 13) for removing the receptacle A with the piston shaft 13 through the free device mouth m. Assembly is preferably carried out in the reverse order.
  • the opening in the area of the free end of the hose connection 58 can be closed by a plug 65.
  • This plug 65 can also be captively connected to the hose connection 58 via a band 66.
