Definitions

  • the invention relates to a method and a tool for crimping contact parts on electrical lines, in which a line end protruding into the tool is to be inserted between the U-shaped crimping claws of a contact part held in the base body of the tool and by a crimping die arranged on the plunger in Interaction with a crimp lower part inserted in the tool body is to be rolled.
  • the insertion of the electrical lines between the raised crimp claws of the contact part is problematic since the alignment of the lines with the raised crimp claws of the contact part is not precise enough.
  • the contact parts with their U-shaped crimping claws are pushed onto the cable end without the cable ends being brought into a position exactly aligned with the crimping claws beforehand. As a result, it often happens that when a line end designed as a stranded wire is pushed in, individual strands hit the contact part, bend and are therefore not included in the crimping.
  • the object of the invention is to improve the known method in such a way that the end of the line to which a contact part is to be crimped is exactly aligned with the raised crimping claws beforehand and, moreover, is not inserted with its end face first between the raised crimping claws.
  • This object is achieved in that the following process features are carried out in the specified sequence of steps: the end of the cable is inserted into the tool lying above the crimping claws, centered by two collapsible jaws and trapped in the two jaws by the plunger, inserted between the two legs of a crimping claw and rolled therein by the crimping die.
  • the lines are not inserted in the axial direction between the two legs of a crimping claw, but are inserted into a crimping claw perpendicularly from above. This means that the above-mentioned shortcomings can no longer occur.
  • the known tools consisting of a base body, - with a crimp lower part, a guide or receptacle for the contact parts, a plunger, which is guided in a shaft of the base body, - With a fixed crimping die, designed according to the invention so that the collapsible jaws are designed as one-armed levers, which are arranged on the part of the base body which guides the plunger and can be moved together by the descending plunger.
  • a further embodiment of the invention is characterized by the following features: On the side from which the line protrudes into the tool, a slide is arranged between the base body and the plunger on the base body, which can be displaced against the spring force in the direction of the crimp lower part, on the slide are two pivotable, pincer-shaped jaws centering the line attached to the im Axles arranged at a distance from one another can be pivoted and are spread apart by a spring force, the plunger has two projections which compress the two jaws when the plunger is lowered.
  • a cushioned lower part which serves as a support for the line, and against which the closed jaws can be moved by the slide on which an edge of the plunger runs.
  • the slide which is pretensioned by a spring, presses the both jaws with their areas of the edges pointing towards the clamping pin between the pivot axes against an attachment connected to the base body.
  • This makes it possible to spread the two jaws apart without a spring being arranged in the immediate area of the two jaws.
  • the cuboid-shaped approach is designed as a sliding block over which the spring-loaded slide carrying the jaws slides.
  • the sliding block is screwed onto a bridge which is placed on the base body from the front and forms part of the guide of the ram.
  • a loose pressure piece is inserted between the sliding block and the jaws. This is easily removable and can be replaced by a pressure piece of a different size.
  • an edge of the slide projects into the effective area of an edge of the plunger, and the distance between these two edges is greater than the stroke of the plunger for compressing the jaws.
  • the side of the lower part serving as a supporting surface for the line is designed as a concave cylindrical surface, the radius of which corresponds to the radius which the free ends of the pivotable jaws describe.
  • the tool is mounted with its base body (1) on the press table and clamped in the press bar (26) with the clamping pin (3) of its ram (2).
  • a guide plate (5) and on this guide strips (6) are fastened, between which the contact parts (18) lined up in a row and attached to the cable ends are gradually guided to an insulating crimper (7) and one Wire crimper (8) and a cutting knife (9) are advanced.
  • the feed takes place by means of a first finger (10), which is pneumatically moved down into an opening (19) of a contact part (18) to be attached, then in the direction of the crimper (7, 8), then up and finally moved back again .
  • a second one While the first finger (10) is moving up, a second one, also pneumatic, moves driven, stationary finger (11) down and engages in another contact part (18) and thus holds the banded contact parts in position. If the first finger (10) moves into a next contact part (18), the second finger (11) releases itself from another contact part (18) and moves up again.
  • the two fingers (10, 11) engaging in the contact parts (18) are thus driven axially in opposite directions.
  • the two fingers (10, 11) are driven axially by one piston each, which is acted upon by compressed air.
  • the compressed air connections in the associated cylinders (12, 13) are marked with (14, 15, 16 and 17). These connections are cross-connected to one another, namely (14) with (16) and (15) with (17).
  • the contact parts (18) are advanced in the direction of the crimper (7, 8) by the first finger (10).
  • the cylinder (12) is driven by the piston rod (20).
  • the cylinder (12) is coupled to the piston rod (20) via the intermediate piece (79) and the pin (22). So that the cylinder (12) is secured against pivoting about the axis of the piston rod (20), the intermediate piece (79) is firmly connected to a bolt (21) which is slidably inserted into the base body (1).
  • the plunger (2) carrying the crimper (7, 8) and the separating knife (9) is inserted into a guide of the base body (1).
  • the ram (2) is coupled to the press bear via the clamping pin (3).
  • This clamping pin (3) is designed as a double offset bolt, which is inserted with its head part (24) into a T-shaped groove (25) of the press bear (26) and with its finger-like free end (27) the head plate (78) of the Plunger (2) penetrates.
  • a compression spring (32) is placed on the end of the clamping pin (3) penetrating the head plate (78) and is prestressed with a clamping ring (23).
  • a screw (28) is inserted into the plunger (2), which is arranged with an eccentrically Bolt (29) engages under the second step of the clamping pin (3) and thus the clamping pin (3) can be raised against the spring (32) when the screw (28) is turned. This makes it easy to insert the clamping pin (3) into the press bear (26).
  • a screw bolt (30) is inserted from the head side, which is rotated via a first screw (31) and thus its height can be adjusted. Should z. B.
  • the screw bolt (30) is unscrewed upwards out of the plunger (2), so that between the plunger (2) and the press bear (26) there is a distance.
  • the compression spring (32) placed on the clamping pin (3) and held under pretension ensures that the ram (2) always lies firmly against the press bar (26). This is particularly important if, when setting the tool, the press bear (26) is shut down without a contact part (18) lying in the tool. Without the compression spring (32), the crimpers (7, 8) would hit hard on the crimp lower part (33).
  • the axial drive of the two fingers (10, 11) and the advance of the cylinder (12) in the axial direction of the piston rod (20) are accomplished as follows:
  • the transverse pin (34) of the axially displaceable bolt (35) slides along and moves on the run-up slope (36) of a block (38) mounted on one side about the axis (37) and fastened to the plunger (2) thus the bolt (35) in direction X.
  • This axially displaceable bolt (35) actuates the valve (40) with its head (39).
  • the cross pin (34) slides along the vertical surface (41) and finally falls back into the latch (42) due to the force of the spring (51).
  • the cross pin (34) slides along the inclined surface (43) and pivots the block (38) against the force of the wing spring (44).
  • the first finger (10) is in the low position and in the position adjacent to the second finger.
  • the valve (40) By actuating the valve (40), compressed air is applied to the slide valve (46), which is designed as a 5/2-way valve with pneumatic control. Compressed air is thus applied to the piston (20) via the channel (50), which thereby moves in the direction Z and advances the first finger (10) engaging in the contact parts (18) in the direction of the crimping device.
  • the control pin (48) strikes the slide (49) and thus actuates the control valve (45), as a result of which compressed air is supplied to the cylinders (13 and 12) via the connections (14 and 16).
  • the second finger (11) moves down and engages in an opening (19) in the contact parts (18), while the first finger (10) moves out of the contact part (18) into its upper position. Delayed by a throttle or similar element, pressure is applied to the slide valve (46) via control lines, which switches over so that the piston rod (20) is pressurized via the channel (47) and moves in the Y direction. In the end position of the cylinder (12), this switches the control valve (45) via the control pin (48). With this, compressed air is applied to the connections (15 and 17) of the cylinders (13 and 12), whereby the second finger (11) is moved out of the contact part (18) upwards, the first finger (10) downwards and into one Opening (19) of the contact parts (18) engages. This completes a transport cycle. A new cycle is triggered by the next pressure pulse from the valve (40).
  • the axially displaceable bolt (35) which exerts a trigger contact on the valve (40), can be actuated by hand will.
  • a force is exerted on the valve-side end of the axially displaceable bolt (35), as a result of which this bolt (35) moves against the force of the spring (51).
  • the cross pin (34) is fixed by a grub screw (52).
  • the stroke position and the stroke of the cylinder (12) is limited by the spacers (53 and 54).
  • the cylinder (13) is screwed onto the base body (1) by cap screws (55). These cap screws (55) can be moved in the slots (56) so that the position of the cylinder (13) can be adjusted.
  • a shoe (57) is pushed onto the two fingers (10, 11) at the free end so that the fingers can be easily adapted to the respective size and shape of the openings (19) of the contact parts (18).
  • the separating knife (9), which works together with the counter knife (58), is, like the wire crimper (8), firmly and immovably connected to the plunger (2) by cap screws (61 and 62).
  • the insulating crimper (7) is adjustable in its depth compared to the wire crimper (8).
  • a second screw bolt (59) is arranged below the screw bolt (30), the height of which can be adjusted by means of a second screw (60). The stroke position of the insulating crimp (7) can thus be adjusted.
  • a bridge (63) is screwed onto the front of the base body (1), which together with the tappet (2) results in a channel (64).
  • a slide (65) is inserted, which rests against a compression spring (66), which is supported on a sliding block (67) screwed to the bridge (63), from the plunger (2) in the direction of the Crimp lower part (33) is displaceable.
  • On this slide (65) there are two pivotable jaws (68) spread by spring force, which are pivoted together by fork-shaped strips (69) when the ram (2) is lowered.
  • the crimping dies (7, 8) bend the raised crimping claws (70) to such an extent that they firmly grip the stripped wire end and the insulating jacket on the one hand with great pressure.
  • the plunger (2) is raised, the jaws (68) with their edges (76) of the end faces lying between the two axes (81) abut against a pressure piece (77), which in turn is supported against the sliding block (67). The two jaws (68) are thus pivoted apart again.
