Description

Lifting tool device, in particular crimping tool device

The invention relates to a lifting tool device, in particular a crimping tool device according to the preamble of claim 1.

A generic lifting tool has a tool head which can be moved linearly in a lifting direction and which can be connected to a press ram of a tool press. The upper tools necessary for the production of a Cri ps are adjustably attached to the tool head, which interact with corresponding counter and lower tools which are attached to a lifting tool base plate. In addition, such crimping tool devices have a feed device for the crimp contact elements lined up belt-like on a scrap strip for feed into the crimping tool, the feed device being driven, for example, by means of a gear mechanism which converts the lifting movement of the tool head into a linearly oscillating feed movement of a feed finger of the feed device. In such crimping tool devices, the individual crimping stamps of the upper tool are fastened in an adjusted manner in the tool head. Likewise, the lower punches of the lower die corresponding to the crimping dies are fastened in an adjusted manner on the base plate of the crimping tool device, so that a defined, closely tolerated position of the upper dies with respect to the lower dies is ensured. Such devices have proven themselves.

After a certain period of operation, however, it is necessary, for. B. when the wear limit is exceeded, both the upper replace the tools as well as the lower tools and replace them with new ones. For this purpose, the tool head for the removal of the upper tool stamp has to be largely disassembled and the old stamp removed, the adjustment of which is lost. The replacement stamps must then be inserted and readjusted.

The work for the lower tool is also to be carried out in the same way, with a large part of the time being spent on the adjustment work after changing the tools. Particularly when the crimp contact elements to be processed are changed frequently, in which case a tool upper or lower part adapted to the size of the crimp contact element has to be mounted on the crimping tool device, the tool change represents a considerable amount of work and thus a large part of the necessary set-up or changeover times ,

The object of the invention is to provide a lifting tool device, in particular a crimping tool device, in which the upper and lower tools can be exchanged easily and quickly, the changeover process being carried out in particular without the use of tools. Furthermore, the tool change should be able to be carried out with little effort and an exact, in particular play-free positioning of the upper and lower tools in the lifting tool device should be ensured.

This object is achieved with a lifting tool device with the features of claim 1. Advantageous embodiments are specified in the subclaims.

In a lifting tool device according to the invention, both its upper tool set and the lower tool set, in particular pre-adjusted, are each designed to form an upper tool module and a corresponding lower tool module in the manner of an insert cassette, with receiving devices for the tool head or on a lifting tool base plate Inclusion of the upper and lower tool modules are provided.

According to a special embodiment, the upper tool module can be latched in the tool head in the manner of a linear bayonet lock, and the lower tool module can be inserted in the form of a slide-in cassette provided with a latching pawl in a corresponding slot in the base plate of the lifting tool device, the latching device interacting with a counter-latching device on the lifting tool device that the lower tool module can be fixed in place with respect to the lifting tool device.

In the lifting tool device according to the invention, it is advantageous that the corresponding upper or lower tool modules can already be prepared in a modular manner in a ready-made upper or lower tool stamp arrangement, so that a complete crimping tool set comprising an upper tool module and a corresponding lower tool module can be prepared, which in the case of a tool exchange, it can be changed simply by unlatching the modules located in the lifting tool device and inserting the exchange modules. By designing the receiving device for the upper tool module as a linear bayonet lock with a manually operated spring catch plate, the upper tool module can be replaced without tools. The lower tool module is replaced by unlatching the latch and inserting the replacement lower tool module until the latching device engages. In this case, too, a tool-free exchange of the lower tool module is guaranteed.

In the following, the invention is explained in more detail by way of example using the drawing. Show it:

A lifting tool device 1 according to the invention (FIG. 1) has a device frame 2 with a base plate 3 and a carrier part 4, a tool head 6 which can be moved back and forth linearly in a working direction 5 for receiving an upper tool module 7, a feed device 8 for belt-like arrangement, for example, on a carrier strip Crimp contact elements (not shown) and a lower tool module 9 which is designed in the manner of an insert cassette and which can be inserted in a locking direction 10 into the lifting tool device 1 and can be removed after unlocking. For the oscillating drive of the feed device 8 in a conveying direction 11, a gear is provided, which converts the lifting movement of the tool head 6 into an oscillating feed movement of a transport finger (not shown) of the feed device 8.

The working direction 5, the mounting direction 10 and the conveying direction 11 are each aligned perpendicular to one another and run parallel to the three spatial axes.

The working direction 5 of the tool head 6 has a stroke orientation 5a and an opposite return stroke orientation 5b.

The conveying direction 11 has a feed orientation 11a and an opposite return orientation 11b.

The mounting direction 10 has an insertion orientation 10a and an opposite disassembly orientation 10b.

The base plate 3 (FIG. 6) is essentially rectangular in shape with a longitudinal extension in the direction of the assembly direction 10 and a transverse extension in the direction of the conveying direction 11. The base plate 3 has a flat groove 16 with a U-shaped cross section adjacent to a longitudinal boundary edge 15 with a groove bottom 17 and two groove boundary edges 18 in its upper side. The flat groove 16 penetrates the base plate 3 over its entire longitudinal extent.

A boom 19 lying in the plane of the base plate 3 extends from the longitudinal boundary edge opposite the longitudinal boundary edge 15 and extends in the conveying direction 11 to its free end 20.

The carrier part 4 is cheek-shaped and extends vertically in the working direction 5 and horizontally in the conveying direction 6, the carrier part 4 with a first column 21 on the free end 20 of the boom 19 and with a second column 22 on the top of the base plate 3 in the connection area of the boom 19 sits adjacent to the groove 16.

The carrier part 4 extends between the two columns 21, 22 at a distance from the arm 19, the second column 22 projecting to approximately flush with the free longitudinal boundary edge 15 of the base plate 3. The carrier part has a gear side 23 and a tool side 24 opposite the gear side 23.

In the end face of the second column 22 facing the flat groove 16 of the base plate 3, a guide groove 25, which is U-shaped in cross section and extends in the mounting direction 10, is introduced, which penetrates the end face 26 of the second column 22.

The partial region of the support part 4 projecting over the base plate 3 has a working side 5 on the tool side 24 extending vertical, cross-sectionally U-shaped flat groove 27 with guide ridges 28 raised on the bottom and guide ridges 29 raised relative to the side edges. Adjacent to the flat groove 27, from the gear side 24, groove web plates 30 are fastened to the carrier part 4, each of which protrudes a little over the groove 27, so that a form-guiding groove is formed for the form-fitting, form-fitting mounting of the tool head 6 in the working direction 5.

In the guide groove 25 sits along the longitudinal direction of the groove a fixable, adjustable adjusting plate 31, which has an elongated hole 32 in the center, via which it can be fixed in a clamped manner with respect to the groove 25 by means of a screw 33. A plate-shaped cantilever 34 is fastened to the end face of the adjusting plate 31 on the transmission side, which has a set screw 35 in its area projecting beyond the adjusting plate 31, which is supported on the second column 22 of the carrier part 4. On the opposite end face of the adjusting plate 31, an essentially L-shaped counter-latching angle 36 is fastened, one leg 37 of which rests against the end face of the adjusting plate 31 and the other leg 38 is cantilevered at a distance from the top of the base plate 3 to approximately the longitudinal center of the flat groove 16 is.

The leg 38 is approximately square in cross section with a tool-side boundary edge 40 and a gear-side boundary edge 41, the corner of the edge 41 facing the flat groove 16 having a chamfer 39. The position of the counter detent angle 36 can be adjusted in the mounting direction 10 via the adjusting plate 31, the extension arm 34 and the adjusting screw 35 and can be fixed in this position by means of the clamping screw 33.

The upper tool module 7 (FIGS. 2, 3) has a stamp receiving device 45 for receiving the upper tool stamp, for example a wire crimp stamp 46, an ejector 47, an insulation crimp stamp 48 and a hammer 49. The punch holder means comprises a U-shaped substantially receiving part 50 having a base plate 51, a first limb web 52 and ^'a second limb web 53rd The leg webs 52, 53 are spaced parallel to one another. At the free end of the leg webs 52, 53 they each have an L-shaped recess 54 on the outside. The first leg web 52 and the second leg web 53 are connected at their free ends to connect a closure plate 55, so that from the base web 51, the first leg web 52, the second leg web 53 and the closure plate 55 a receiving shaft 56 for receiving the upper tool punches 46, 47, 48, 49 is formed. The receiving shaft 56 extends in the working direction 5 and is open on both sides, that is to say open at the top and bottom. The closure plate 55 laterally projects over a L-shaped recess 54 with a groove web 58, so that the closure plate 55 together with the L-shaped recesses 54 in the leg webs 52, 53 each form a guide groove 57. The groove web 58 projecting beyond the L-shaped recess 54 has a recess 59 approximately at half its height, so that an upper and a lower closure web 60, 61 are formed, the operation of which is explained in more detail below. The closure webs 60, 61 are closely tolerated in their thickness, so that the upper tool module - as described below - can be used without play in a countermeasure.

From the outside of the second leg web 53, a slit-shaped horizontal recess 62 is made at about half its vertical height, which penetrates the second leg web 53 and continues in the base web 51 for a while. Corresponding to the slot-shaped recess 62, a slot-shaped recess 63 is also made in the closure plate 55, the depth of which in the closure plate 55 corresponds to the depth of the slot recess 62 in the base web 51.

In the slot-shaped recesses 62, 63 is from the end plate side a locking bolt 64 can be inserted in a direction 65.

The locking bolt 64 is essentially cuboid and is supported with its one longitudinal half in the slot recess 62 seated on the second leg web 52 and protrudes with its second longitudinal half into the receiving shaft 56.

An end plate 66 is placed against the outside of the second leg web 53, which closes the slot-shaped recess 62, so that when the locking bolt 64 is inserted, it is secured against falling out. The end plate 66 has as an axial stop for the locking bolt 64 a stop tab 67 which projects into the recessed part of the slot-shaped recess in the base web 51 at least to such an extent that an unintentional insertion of the locking bolt 64 or a falling out of the locking bolt 64 in its continued insertion direction 65 is avoided.

An upper edge 68 of the base web 51 is designed to be lowered with respect to the upper edges of the leg webs 52, 53 and the closure plate 55, so that a step 69 is formed.

The wire crimping die 46 is of flat, rectangular plate shape with an upper end edge 72, a lower end edge 73 and a first longitudinal limiting edge 74 and a second longitudinal limiting edge 75. The width of the wire crimping die 74, that is to say the distance between the longitudinal boundary edges 74 and 75, is selected such that the wire crimping die 46 can be inserted into the receiving slot 56 without play, the longitudinal limiting edges 74, 75 each being the inside of the leg webs 52, 53 of the receiving part 50 face each other. The upper end edge 72 is flat. The lower end edge 73 has a shape recess 76, which is transverse to the core crimping die 46 and which, in a known manner for the production of a wire crimp, is designed to taper and has crimp shape arches on the base of the recess is. The wire crimping die 46 has a slot recess 77 approximately in the upper third, which extends a little from the second longitudinal boundary edge 75 in the direction of the longitudinal central plane of the wire crimping die 46. The slot recess has an upper boundary surface 78 and a lower boundary surface 79, which are arranged at a distance from one another in such a way that the cuboid locking bar 64 is guided between the boundary surfaces 78, 79 with or without play.

The ejector 47 is flat in the form of a rectangular plate and has an upper end edge 80, a lower end edge 81 and two longitudinal edges 82, 83 and is somewhat narrower in its width than the wire crimping die 46. A triangular ejector notch 84 is introduced into the lower end edge 81 approximately in the center. In the corner area between the upper end edge 80 and the longitudinal edges 82, 83, the ejector 47 has L-shaped recesses 85, so that an actuating tab 86 is formed. Analogous to the wire crimping die 46, the ejector 47 in the upper quarter has a recess 87 which extends from the longitudinal edge 83 to the longitudinal center of the ejector. The recess 87 is bounded analogously to the slot recess 77 by an upper and a lower boundary edge (not shown), these being at a greater distance from one another in comparison to the upper and lower boundary edges 78, 79 of the slot recess 77 in the wire crimping die 46, so that the ejector 47 with play, in particular about 3 mm, is held in its longitudinal direction by the bolt 64.

The insulation crimping die 48 is, like the wire crimping die 46, flat-plate-shaped with an upper end edge 90, a lower end edge 91 and two longitudinal edges 92, 93 and can be inserted into the receiving slot 56 without play. A form recess 94 extends from the lower end edge 91 analogously to the wire crimping die 46, which recess is initially displaced in a known manner to produce an insulation crimp. young and with shaped arches on the base of the recess, a piece extends in the longitudinal direction of the insulation crimping die 91. Similarly, the insulation crimping die 48, analogous to the wire crimping die 46, has on its second longitudinal edge 93 a slot recess 95 with an upper boundary edge 96 and a lower boundary edge 97, which extends a little from the second longitudinal edge 93 in the direction of the longitudinal center of the insulation crimping stamp 48. The distance between the boundary edges 96, 97 of the slot recess 95 is enlarged compared to that of the boundary edges 78, 79, so that the insulation crimping die 48 can be fixed with a longitudinal play by the locking bar 64 in the receiving shaft 56. On a flat side 98, the insulation crimping die 48 has a flat groove 99 over its entire longitudinal extent, into which the ejector 47 can be inserted and is held displaceably in the longitudinal direction. The depth of the flat groove 99 corresponds to the material thickness of the ejector 47 or is somewhat larger.

The hammer 49 is flat in the form of a rectangular plate with an upper end edge 100, a lower end edge 101 and two longitudinal edges 102 and 103 and can be inserted in the receiving shaft 56 without play or with a small amount of play on the insulation crimping die 91. A notch recess 104 extends centrally from the lower end edge 101 in the longitudinal direction of the hammer, so that two hammer end surfaces 105 are formed from the lower end edge 101.

About about the upper half of a flat side 106 of the hammer 49, the hammer 49 is formed to have a step surface 107 with thin walls. Analogous to the other upper tool punches 46, 48, the hammer in its upper quarter also has a slot recess 108 which extends from the second longitudinal edge 103 in the direction of the longitudinal center of the hammer 49 and has an upper boundary edge 109 and a lower boundary edge 110. The boundary edges 109, 110 point towards one another a distance that corresponds approximately to the distance between the boundary edges 96, 97, but in any case is greater than the distance between see the boundary edges 78, 79 of the slot recess 77 of the wire crimping die 46.

According to a further embodiment (see FIG. 1), the recess in the lower end edge 101 can also be designed as an L- or J-shaped recess, so that only one hammer end surface 105 is formed.

The wire crimping die 46, the ejector 47, the insulation crimping die 48 and the hammer 49 form the upper tool package 115, which is arranged as follows in the receiving slot 56 of the stamp receiving device.

The wire crimping die 46 sits with a flat side adjacent to the closure plate 55 on the inside thereof facing the receiving shaft 56. The ejector 47 rests with a flat side on the free flat side of the wire crimping die 46. Following this, the insulation crimping die 48 is placed against the ejector 47 in such a way that it is slidably received in the shallow groove 99 of the insulation crimping die 48. The hammer with its non-stepped flat side is placed against the free flat side of the insulation crimping die 48. In the upper tool set 115, the individual tools 46, 47, 48, 49 are aligned such that their shaped recess 76, the ejector notch 84, the shaped recess 94 and the notched recess 104 are arranged pointing in the same direction. In addition, the individual tools 46, 47, 48, 49 are assigned to one another in such a way that the slot recesses 77, 87, 95, 108 are each aligned approximately with one another, so that the locking bolt 64 can be pushed through.

This bundled upper tool set 115 is pushed into the receiving chute 56 from the open underside thereof until the step 107 abuts the lower edge of the base web 51. In this position, the slot recesses 77, 87, 95, 108 are aligned with the recesses 62, 63 in the stamp receiving device 45, so that by inserting the locking bolt 64 the upper tools of the upper tool set 115 are held in a form-fitting manner in the stamp receiving device 45. Due to the larger slot widths of the slot recesses 87, 95, 108 and the precisely fitting manufacture of the upper tools with regard to their thickness and width, the ejector 47, the insulation crimping stamp 48 and the hammer 49 are in this pre-assembled arrangement of the upper tools in the stamp receiving device 45 Longitudinal direction in the receiving shaft 56 can be moved longitudinally without play.

This arrangement of stamp receiving device 45 and the bundled upper tool set 115 inserted into the stamp receiving device 45 forms the upper tool module 7. The position of the slot recesses 77, 87, 95, 108 in the upper tool parts 46, 47, 48, 49 is chosen such that the upper end edges 72, 80 are arranged at the same level slightly above the top of the leg webs 52, 53 and the upper end edges 90, 100 relative to one another and with respect to the upper end edges 72, 80 are arranged in a stepped manner when the upper boundary edges of the slot recesses 77, 87, 95, 108 each rest on the locking bar 64 in the assembled state of the upper tool module 7. In this position, the lower end edges 73, 81, 91 of the wire crimping die 46, the ejector 47 and the insulation crimping die 48 are aligned with one another, the lower end edge 101 or the hammer end faces 105 being arranged somewhat recessed in the direction of the stamp receiving device 45.

The wire crimping die 46 and the ejector 81 have a longitudinal extent h, compared to which the longitudinal extent of the insulation crimping die 48 and the hammer 49 is somewhat smaller.

The lower tool module 9 (FIGS. 6, 7) is designed in the manner of an insert cassette with a cassette base body, the cassette base body being constructed in two parts from a base plate 120 and a guide bar 121. The cassette base body serves to hold the lower tools and to mount would take a locking device, in particular a locking pawl 122 for locking the lower tool module 9 in the device frame 2 of the lifting tool device 1 without play.

The base plate 120 is essentially flat-plate-shaped with a double stepped upper side 123, a flat lower side 124, a first side edge 125 and a second side edge 126 and a first free end edge 127 and an opposite second end edge 128. The stepped upper side 123, starting from the free end edge 127, forms a first step 129 and a second step 130 with an abutment surface 131, the first step 129 having an insertion bevel 132. The guide strip 121 is placed against the second side edge 126, the upper side 135 of which follows the contour of the upper side 123 and the longitudinal extent of which corresponds to the longitudinal extent of the base plate 120. The guide bar 121 has a free side edge 136, which is spaced parallel to the first side edge 125 of the base plate 120, the distance between the first side edge 125 and the free side edge 136 corresponding to the distance between the groove side edges 18 of the flat groove 16 in the base plate 3, so that the cassette base body can be inserted without play into the flat groove 16.

According to a further embodiment (FIG. 1), the side edge 125 and the free side edge 136 can have sliding projections 141.

In the area between the first step 129 and the second step 130, an elongated hole-shaped recess 137, which extends in the longitudinal direction of the base plate 130 and in which the latching pawl 122 is resiliently pivotable about an axis 138, which is arranged adjacent to the first step 129, is introduced approximately transverse to the cassette base body is stored. The detent pawl 122 has a sliding surface 139 and a detent edge 140 which faces the stop surface 131. In the area between the second step 130 and the second end edge 128, a top view L-shaped recess 142 is made in the top side 123, which is delimited on one side by an inner side 136a of the guide bar 121, so that a U-shape which is approximately square in the top view shaped recess is formed in the cassette base body. In the recess 142 sits positively in the direction of the longitudinal extent of the cassette base body, a contact piece 143 which can be fastened against the inside 136a by means of a screw 143a. The contact piece 143 is plate-shaped and has an anti-rotation bar 143c on the inside, which engages in a corresponding L-shaped recess 143d and guide bar 122, so that rotation of the contact piece 143 is avoided when the screw 143a is tightened. The contact piece 143 has a recess 144, in which a support device 145 is seated and adjustable in height.

The support device 145 is essentially L-shaped and has a plug leg 146 and a support leg 147. The top of the support leg 147 serves as a support surface for the contact area of a crimp contact element to be processed.

A lower tool 150 corresponding to the wire crimping die 46 and the insulation crimping die 91 is seated in the recess 142 against a front face 143b of the contact piece 143, which is designed with a step x, which is equipped in a known manner with a supporting zone for the wire crimp and the insulation crimp of a crimp contact element , The lower tool 150 has a stepped rear side corresponding to the stepped front side 143b, so that the lower tool 150 is positioned in a defined manner in relation to the inner side 136a. The dimension build-up for the tolerance-minimized position of the lower tool 150 takes place from the free side edge 136 via the precisely made guide bar 121 onto the lower tool base block 150a and thus onto the lower tool anvil Against the second end edge 128, the recess 142 is finally attached, in particular screwed, by a knife holder 152 by means of screws 152a. The knife holder 152 supports a punch knife 153, which projects about its center and projects beyond its upper side and is spring-loaded in the working direction 5. The punch knife 153 has, in a known manner, a first cutting edge 154 which interacts with a corresponding counter cutting edge 155 on the lower tool 150 and a second cutting edge 156 which cooperates with a corresponding counter cutting edge 157 on the knife holder 152. The cutting edges 154, 155 serve to separate the crimp contact element from the carrier strip (not shown). The second cutting edge 156 and its counter-cutting edge 157 serve to comminute the carrier strip remaining as scrap, the two cutting edge arrangements 154, 155 and 156, 157 being arranged approximately at right angles to one another. The punch knife 153 has an actuating face on its upper side corresponding to the hammer face 105 of the hammer 49. After the knife holder 152 is screwed on, the abutment piece 143 is displaced in the direction of the knife holder 152 when the screws 143a are loosened, until the lower tool 150 is free of play in the longitudinal direction in the cassette base body sits and still a vertical clearance of the knife 153 is guaranteed.

The above-described arrangement of cassette base body, locking pawl 122, pressure piece 143 with support device 145, lower tool 150 and knife holder 152 with the punch knife 153 form the lower tool module 9, which can be inserted as a unit into the shallow groove 16 of the base plate 3 so that the stop surface 131 on the Limiting side 40 of the counter-locking angle and the locking pawl 122 rests with its locking edge 140 on the chamfer 39 without play and thus the lower tool module 9 both in its longitudinal direction, that is in the mounting direction 10, and in its transverse direction, that is in Direction of conveyance 11 is set without play.

The tool head 6 (FIGS. 4, 5) has an essentially rectangular support part 160 with an upper end face 161, a lower end face 162, a first flat side 163 facing the tool side 24 of the support part 4, a second flat side 164 opposite this and two Side surfaces 165 on.

In the area of the upper half of the carrier part 160 in the working direction 5, from the second flat side 164, there are webs 166, 167 which are vertically spaced and parallel to one another and which are flush on the outside with the side surfaces 165, are flush on the upper side with the first end face 61 and have end edges 168 on the underside , which are arranged at right angles to the second flat side 164. The webs 166, 167, with their inner sides 169, 170, delimit a vertically running, cross-sectionally U-shaped groove 171, the groove bottom 172 of which extends a piece outstandingly parallel to the second flat side 164. The webs 166, 167 are limited in their extension by end edges 173, 174. In the vertical center, the webs 166, 167 have groove recesses 175, 176 which extend away from the end edges 173, 174 and are U-shaped in cross section and are flush with one another, each of which has an upper boundary edge 177 and a lower boundary edge 178 running parallel thereto, and also one groove bottom

179 are limited.

At the vertically upper and vertically lower ends of the webs 166, 167 are threaded bores from the end edges 173, 174, respectively

180 introduced.

Between the groove recess 175 of the first web 166 and its lower end edge 168, from the end edge 173 an open to the interior of the groove 171 towards the inside, with an overcircular cross section 181 is made, the bottom of which is a distance from the groove bottom 172. Against the rear first flat side 163, a guide plate 184 is set and fastened over the entire vertical longitudinal extent of the carrier part 160, which laterally projects a bit beyond the carrier part 160, so that sliding webs 185, 186 are formed with which the tool head can be positively displaced vertically into that of the flat groove 27 and the groove web plates 30 limited guide groove can be used.

The carrier part 160 has a vertical blind hole 187 adjacent to the top of the groove bottom 172 for receiving an adjustment device 188 for the wire crimping die 46. The adjusting device 188 has a plug pin 189 and at one end of which a circular disk-shaped adjusting disk 190 is attached. The shim 190 has a radially outgoing stop, arranged in the manner of a thread, with a stop face 192 on the underside and an adjustment scale. At the end of the plug pin 189 on the adjusting disc side there is a T-bolt 193 on the end face which, together with the end 190 of the plug bolt 189 on the adjusting plate side, forms a connection device to a press ram (not shown in a tool press (not shown) in a known manner. The setting device 188 can be inserted into the blind hole 187 and can be fixed there axially and in a rotationally secure manner.

In the second end face 162 on the underside, a receiving groove 195 with a U-shaped cross section is introduced over the entire transverse extent of the carrier part 160, in which a substantially L-shaped connecting piece 196 with a vertically running connecting leg 197 for connecting a toothed rack 198 and a horizontally running fastening web 199 sits for attachment to the support member 160. The horizontal fastening web 199 has a transverse groove recess 200, in which a locking / unlocking key 201 is slidably seated. The locking / unlocking button 201 has a guide web 202, a stop web 203 which extends downward at one end from this end, and other finally an operating tab 204. The locking / unlocking button 201 is spring-loaded in the transverse groove 200, a compression spring 205 being supported at one end on the stop bar 203 and at the other end, for example, on the guide plate 184.

In the assembled state, the upper edge of the actuating tab 204 projects a little beyond the second flat side 164 of the carrier part 160. When the locking / unlocking button 201 is actuated, that is to say by pressing the operating tab 204, the locking / unlocking button 201 can be pressed in at least to such an extent that the operating tab 204 is flush with the second flat side 164.

In the corner area between the second flat side 164 and the side surfaces 165, a locking counterpart 210 is fastened, e.g. pinned and screwed, which consists in cross-section L-shaped of a mounting plate 211 and two from each of these perpendicularly extending locking webs 212. The locking webs 212 extend parallel and spaced apart from the second flat side 164 and are at a distance therefrom which corresponds to the thickness of the locking plate 55, so that a counter-guide groove corresponding to the guide groove 57 of the upper tool module 7 is formed. The locking webs 212 of the locking counterparts 210 are each arranged vertically at a distance from one another which corresponds to the vertical extension of the upper locking webs 60 of the locking plate 55 of the upper tool module 7. The locking counterparts 210 are each flush on the underside with the second end face 162 of the carrier part 160.

A first pressure piece 220 for actuating the wire crimping die 46, an actuating lever 221 pivotably mounted in the recess 181 for actuating the ejector 47 and a second pressure piece 222 for actuating the insulation crimping die 48 and the hammer 49 sit successively in the groove 171 from the groove bottom 172. The first pressure piece 220 is flat-plate-shaped with a first flat side 225, a second flat side 226, two side edges 227, a lower actuating end edge 228 and has a stop web 229 at the end opposite the actuating edge 228 with an upper elevation 230, which is a piece of extends the first flat side 225 away. The first pressure piece 220 is displaceably and longitudinally displaceably guided over the side edges 227 in the groove 171, the first flat side 225 and the groove arch 172 lying opposite one another and the stop web 229 resting on the first end face 161 of the carrier part 160.

The actuating lever 221 is plate-shaped with a circular disk-shaped joint plate 231 corresponding to the recess 181 and a bracket 232 formed thereon, which projects into the groove interior of the groove 171. The actuating lever has a first flat side 233 and a second flat side 234. The arm 232 is tapered at its free end with an inclined or curved actuating surface 235 and has a U-shaped recess 236 on its upper peripheral edge and a round cam 237 opposite it on the lower peripheral edge. The actuating lever 221 lies with its first flat side 233 on the second flat side 226 of the first pressure piece 220 and can be pivoted up and down in the interior of the groove 171 in a limited area.

Approximately perpendicular to the actuating surface 235 of the actuating lever 221, the web 167 penetrates an oblique bore 238 approximately at the level of the groove recess 176, in which sits a positive actuating pin 239, which sits on the actuating surface 35 with its nut-side end and a piece with its free end over the side surface 165 protrudes when the actuating lever 221 is arranged in a pivoted position which is deflected upward with respect to the lower limit pivot position. In the lower limit swivel position (see FIG. 9) of the actuating lever 221 detents the forced actuation pin 239 in its basic position, in which it does not or only insignificantly projects beyond the side surface 165 with its free end.

The second pressure piece 222 is essentially cuboid with a first flat side 240, a second flat side 241, side edges 242, an upper end edge 243 and a lower end edge 244. The second flat side 241 has a wedge-shaped groove 245 with a horizontal upper boundary edge 246 and an oblique lower boundary edge 247 for receiving an adjusting wedge 248. The rear flat side 240 of the pressure piece 222 has a cross groove pattern with a wide horizontal groove 250 and a narrow vertical groove 251 running vertically in the center (cf. FIGS. 8, 9; broken line).

In the extension of the narrow vertical groove 251, starting from the lower edge of the horizontal groove 250, a vertical groove 251a, which is somewhat wider than the vertical groove 251, is introduced, which enables the circular cam 237 to penetrate to below the lower end edge 244.

The cross groove pattern has a depth which corresponds approximately to the material thickness of the actuating lever 221 and is arranged such that the arm 232 can be freely pivoted in the wide horizontal groove 250. A compression spring 252 is inserted into the narrow vertical groove 251, which is supported at one end on the upper end region of the vertical groove 252 and at the other end in the recess 181 of the actuating lever 221 and thus presses it into its lower limit pivot position (see FIG. 9).

The setting wedge 248 (FIG. 4) is plate-shaped with a horizontal top edge 260, an oblique bottom edge 261, a narrow end edge 262 at the tapered end of the setting wedge 248 and a broad end edge 263 at the thickened end of the setting wedge 248. The setting wedge 248 sits in the keyway 245 and The second pressure piece 222 protrudes laterally a bit, so that the tapered end protrudes a bit into the groove recess 176 and the thickened end into the groove recess 175 (see FIG. 10). In the area of the thickened end, the setting wedge 248 has a horizontal bore in which an actuating pin 265 is seated, which projects a little away from the second pressure piece 222 and from the setting wedge 248. The pin 265 protrudes with its free end into a spiral groove (not shown) of a setting wheel 266, which is rotatably supported about a horizontal axis 267, so that by rotating actuation of the setting wheel 266 the setting key 248 in the keyway 247 of the second pressure piece 222 back and forth is displaceable here and thus, depending on the position of the setting wedge 248 in the keyway 245 of the second pressure piece 222, whose vertically upper stop is variably adjustable.

A cover 268 is placed against the end edges 173, 174, the groove 171 closing on the front side, and fastened by means of screws which engage in the threaded bores 180. A hole 269 is made approximately centrally in the cover 268 and receives a bolt (not shown) on which the adjusting wheel 266 is rotatably mounted about the horizontal axis 267.

A pressure plate 270 is placed against the lower end edge 244 of the second pressure piece 222 and fastened with a screw 271.

The pressure plate 270 has a longitudinal edge 272 facing the groove bottom 172, an opposite longitudinal edge 273 and two end edges 274, each of which is flush with the side edges 242 of the pressure piece 222. The longitudinal edge 272 has two projections 275 on the outside, so that a groove for the actuating tab 86 of the ejector 47 is formed between the projections 275, delimited by the longitudinal edge 272. The underside of the pressure plate 270 facing away from the pressure piece 222 serves as an actuating surface for the upper end edges 90, 100 of the insulation crimp 48 or the hammer 49 Thus, the upper stop of the first pressure piece 220 and thus the vertical upper positioning of the wire crimping die 46 is made possible by turning the adjusting device 188, the elevation 230 interacting with the spiral stop surface 192.

The vertically upper stop for the insulation crimping die 48 and the hammer 49 relative to the wire crimping die 46 is represented by the second pressure piece 222 together with the pressure plate 270, the vertically upper stop position thereof via the adjusting wedge 248, the pin 265 and the adjusting wheel 266 relative to the upper stop position of the Core crimp stamp 46 is adjustable. The actuating tab 86 of the ejector 47 can penetrate between the protrusions 275 of the pressure plate 270 and through the groove 251a and cooperate with the round cam 237 of the actuating lever 231. If the ejector 47 remains after crimping a crimp contact element, e.g. Because of a jamming of the crimped contact element in the wire or insulation crimping dies 46, 48, in a raised position relative to the crimping dies 46, 48, the actuating lever 221 is in a pivoted position raised in relation to the lower limit pivoting position, the pin 239 being a part of the Hole 238 protrudes. During the return stroke of the tool head, for example, the free end of the pin 239 slides along a sliding surface and thus forcibly moves the actuating lever back into its lower limit pivot position, as a result of which the ejector 47 is moved vertically downward relative to the crimping dies 46, 48 and thus by means of its ejector notch 84 a possibly jammed crimp contact element releases from the crimping dies 46, 48.

The second flat side 164 of the carrier part 160, together with the locking counterparts 210 and the locking / unlocking button 201, forms a receiving device for the upper tool module 7. The use of the upper tool module 7 in the tool head 6 is done as follows:

First, the upper tool module 7 is to be placed with its locking plate 55 first on the second flat side 164, the locking / unlocking button being pressed in against the spring pressure of the spring 205. The closure webs 60, 61 of the closure plate 55 are arranged vertically downwards to the closure webs 212 of the closure counterparts 210, so that the closure webs 60 can penetrate between the closure webs 212. Thereupon, the upper tool module 7 is to be pushed vertically upwards in the working direction 5, so that the locking webs 60 engage behind the upper locking webs 212 and the locking webs 61 engage behind the lower locking webs 212 until the upper sides of the leg webs 52, 53 come to rest with the lower end edges 168 (See dashed assembly arrows in (FIG. 1). In this position, the locking / unlocking button 201 snaps into its starting position due to the spring pressure and automatically locks the upper tool module 7 in this vertical position.

By simply pressing the locking / unlocking button 201, the upper tool module 7 is released downwards again, so that it can be removed from the tool head 6 in reverse order.

Thus, the locking plate 55 works together with its locking bars 60, 61 and the counter-locking pieces 210 with their locking bars 212 and the locking / unlocking button 201 in the manner of a linear bayonet lock, which can be unlocked by simply pressing the locking / unlocking button 201.

The feed device 8 (FIG. 1) has a conveyor finger carriage 290 which can be moved back and forth in the conveying direction 11 and has a conveyor finger receiving device 291, the conveyor finger carriage 290 reaching through the carrier part 4 above the boom 19, so that the conveyor finger receiving device 291 is the same Tool side 24 is arranged upstream. Furthermore, the feed device comprises a feed rail 292, which rests on one end on an adjusting device 294 on the base plate 3 and has a support 295 on the other end. The feed device 8 serves to feed the crimp contact elements arranged on a carrier strip (not shown) between the upper tools 46, 47, 48, 49 and the lower tools 145, 150, 153 of the lifting tool device 1, the feed rail 292 in the direction 10 using the adjusting device 294 is adjustable so that the crimp contact elements come to lie in the correct position with respect to their longitudinal extent on the lower tool stamp 150.

According to a special embodiment (FIG. 11), the locking edge 140 is designed as a curved cylinder jacket section surface with a radius of curvature R, the central axis 300 of the associated cylinder being arranged eccentrically, in particular eccentrically with respect to the sliding surface 139, with respect to the pivot axis 138 of the locking pawl 122. This ensures an improved play-free fit of the lower tool module with different dimensional tolerances of the counter-locking leg 38. In addition, the curved design of the locking edge 140 always ensures line contact with the chamfer 39. Touching the latch 122 with the corners of the chamfer is excluded.

With such a crimping tool device according to the invention, it is particularly advantageous that corresponding upper tool modules 7 and lower tool modules 9 can be pre-assembled and combined to form a lifting tool set and can be stored as exchange modules for different crimp contact element sizes or types or as a replacement for worn upper or lower tool stamps and if necessary, the built-in upper and lower tool modules can be replaced by replacement modules in a very simple manner, the user-friendly design of the locking devices for the tool modules Use of assembly tools is avoided. The tool modules can be exchanged with little effort simply by pressing the corresponding unlocking devices. Nevertheless, the advantages of a separate wire crimp stamp adjustment via an adjustment device on the tool head and a separate insulation crimp adjustment using a setting wheel on the front of the tool head are fully retained. These adjusting devices no longer have to be disassembled for exchanging the tool modules, so that complex disassembly and subsequent assembly of the adjusting devices can be dispensed with.
