Description

The present invention relates to a crimping device, in particular a crimping device as defined in the preamble of the main claim 1.

BACKGROUND OF THE INVENTION

A pressing device (or also a lifting tool) of this type has a linearly displaceable tool head in the stroke direction, which is connectable to the press ram of the pressing tool. On the tool head there are adjustable upper tools necessary for forming a flange which cooperate with corresponding counter-tools or lower tools which are fixed on the base plate of the pressing device. In addition, the crimping device of this type has a feeding device for strip-shaped crimping contact elements for feeding into the crimping tool, the feed device being driven, for example, by a drive which converts the stroke movement of the tool head into a linear oscillating displacement movement . In such crimping devices, the individual crimping punches of the upper tool are adjustable in the tool head. Likewise, corresponding lower punches of the lower tool are fixedly adjustable on the base plate of the crimping device, so that a defined, narrowly limited position of the upper tool relative to the lower tool is ensured. Such devices have already proven themselves in practice.

* · · · · · ··· · ϊ ·· · .. ·;

However, after a certain period of operation, it is necessary, for example, to exceed a certain wear limit, to replace both the upper tool and the lower tool and to replace them with new ones. To this end, the tool head for removing the punches of the upper tool must be largely disassembled and the old punches must be disassembled while their setting is disrupted. Subsequently, spare punches must be fitted and reset to the correct position.

Logically, for the lower tool, θ must also be carried out, with a larger proportion of the required working time being allocated to the setting operations after the tool has been replaced. Particularly in the case of frequent replacement of the crimping contact element to be machined, in which a tool extension or base corresponding to the size of the crimping contact element has to be mounted on the crimping device, the tool change represents a considerable labor cost and thus a large part of the preparation time required.

The object of the present invention is to provide a pressing device, in particular a crimping device, in which the upper and lower tools can be easily and quickly replaced, the preparation process being carried out in particular without the use of auxiliary tools. Furthermore, the tool change should be carried out by exerting little force and ensuring that the upper or lower tool is positioned accurately, in particular without play, in the pressing device.

SUMMARY OF THE INVENTION

The above object is achieved according to the present invention by a pressing device defined by the features set forth in claim 1. Preferred embodiments of the present invention are set out in the dependent claims.

(J of the pressing device according to the present invention, both its upper tool set and the lower tool set are each preset to the upper tool module and the corresponding lower tool module in the form of an insertion cassette, receiving means for receiving the receiving the upper and lower tool module respectively e.

According to a particular embodiment, the upper tool module is snap lockable by means of a linear bayonet lock and the lower tool module in the form of a snap-on cassette provided with a snap-on latch is snapped into a corresponding snap-in recess in the press plate base. the bottom tool module is precisely fixed relative to the pressing device.

With the press device according to the present invention, the advantage is that the corresponding modules of the upper and lower tools can be pre-modularly prepared already in the ready-made configuration of the punches of the upper and lower tools, so that the lower tool module, which can be replaced only by simply tilting the modules and pressing the interchangeable modules in the event of a tool change. By providing a receiving means for the upper tool module as a linear bayonet closure with a manually operable resilient snap plate, the replacement of the upper tool module can take place without the use of an auxiliary tool. The lower tool module is replaced by tilting the latch and inserting the lower tool change module until the latch engages. In this case too, the replacement of the lower tool module is ensured without the use of auxiliary tools.

In the following, the present invention will be explained in more detail by way of example embodiments with reference to the accompanying drawings.

The upper tool module 7 (see FIGS. 2 and 3) has a punch receiving means 45 for receiving the upper tool punches, such as a conductor crimping punch 46, an ejector 47, an insulating crimping punch 48, and a hammer 49.

The punch receiving means has a substantially U-shaped receiving portion 50 with a bottom wall 51, a first side wall 52 and a second side wall 52. The side walls 52, 53 are arranged parallel to each other. At the free ends of the side walls 52, 53, these walls always have outer faces

The side wall 52 and the second side wall 53 are connected at their free ends at their free ends.

4 f is fastened with a closure plate 55 such that a receiving shaft 56 is formed from the bottom wall 51, the first side wall 52, the second side wall 53 and the closure plate 55 to receive the punches 46, 47, 48, 49 of the upper tool. This receiving shaft 56 extends in the working direction 5 and is open on both sides, i.e. up and down. The closure plate 55 extends over the groove wall 58 at the sides of the L-shaped recesses 54, so that the closure plate 55 together with these L-shaped recesses 54 in the side walls 52, 53 each form a guide groove 57. L has a recess 59 approximately halfway through its height, so that one upper and one lower closure wall 60, 61 are formed, the function of which will be explained in more detail below. The closure walls 60, 61 have a thickness within strict tolerances so that the upper tool module - as will be described in more detail below - can be placed in a counter-bearing without play.

A horizontal slot recess 62 is formed from the outside of the second side wall 53 at approximately half its vertical height, extending through the second side wall 53 and continuing partially into the bottom wall 51. Corresponding to the slot recess 62, a slot slot 55 is also formed in the closure plate 55. The depth in the closure plate 55 corresponds to the depth of the slot recess 62 in the bottom wall 51.

A plug 64 can be inserted into the slot recesses 62, 63 in the direction 65 of the closure plate.

The crimping punch 46 is formed as a flat rectangular plate with an upper end edge 72, a lower end edge 73, and a first longitudinal edge 74 as well as a second longitudinal edge 75.

20, the distance between the longitudinal edges 74 and 75 is selected such that the crimping punch 46 can be inserted into the receiving shaft 56 without play, the longitudinal edges 74, 75 always facing the inner sides of the side walls 52, 53 of the receiving part 50. the leading edge 72 is a flat plane. The lower leading edge 75 has a recess 76 transversely with respect to the crimping punch 46, which tapers in a known manner to form a vein flange and which is formed with an elbow arch at the bottom of the recess. The crimping punch 46 has in its upper third approximately a slot recess 77 which extends from

3Q of the second longitudinal edge 75 partially in the direction of the longitudinal central plane of the crimping punch 46. This slot recess has an upper edge surface 78 and a lower edge surface 79 which are spaced apart so that the plug 64 in the form of a cuboid, it is guided between these outer surfaces 78, 79 without play or almost without play.

The ejector 46 is formed as a flat rectangular plate and has an upper leading edge 80, a lower leading edge 81 as well as two longitudinal edges 82, 83, being somewhat narrower than the crimping punch 46 in its width dimension. an approximately triangular notch 84 of the ejector is formed transversely. In the corner regions between the upper leading edge 80 and the longitudinal edges 22/83, the ejector 47 has an L-shaped recess 85 so that a control protrusion 86 is formed. Analogously to the crimping punch 46, the ejector 47 has an upper quarter from the longitudinal edge 83 to the longitudinal center This recess 87 is bounded, by analogy to the slot recess 77, by an upper and a lower edge surface (not shown), these surfaces being compared to the upper and lower edge surfaces 78, 79 of the slot recess 77 in the flanging.

The punches 46 have a greater distance from each other, so that the ejector 47 is held in its longitudinal direction from the plug 64 with a clearance, in particular approximately a clearance of 3 mm.

The insulation crimping punch 48 is analogous to the crimping punch 46 in the form of a flat rectangular plate 25 with an upper front edge 90, a lower front edge 91 as well as two longitudinal edges 92, 93 and is slidable into the receiving shaft 56 without clearance. in the longitudinal direction of the crimping punch 91 extends partly analogously to obrubovacímu punch 46 shaped recess 94 ^- which in known manner to form first bead isolation ·· * ♦ »· narrows at the bottom of the recess has an arc shape. Also, analogously to the crimping punch 46, the crimping punch 48 has at its second longitudinal edge 93 a slot recess with an upper edge surface 96 and a lower edge surface 97 that extends from the second longitudinal edge 93 partially in the longitudinal direction of the crimping punch 48. The spacing of the end faces 96, 97 of the slot recess 95 is increased relative to the spacing of the end faces 78, 79, so that the crimping punch 48 is positioned by the plug 64 in the receiving shaft with longitudinal clearance. On the flat side, the hemming punch 48 has a flat groove 99 over its entire length into which the ejector 47 can be inserted, which is thus held movable in the longitudinal direction. The depth of the flute 99 corresponds to the material thickness of the ejector 47 or is somewhat greater.

The hammer 49 is also formed as a flat rectangular plate with an upper front edge 100, a lower front edge 101 as well as two longitudinal edges 102 and 103 and is analogous to the crimping punch 48 slidable into the receiving shaft 26 without or with little play. A notch recess extends from the lower leading edge 101 in the center in the longitudinal direction of the hammer

104, so that two hammer faces 105 are formed from the lower leading edge 101.

Roughly above the upper half of the flat side 106 of the hammer 49, the hammer 49 is formed as a thin wall by a step surface 107. Analogously to the other crimping punches 46, 48 of the upper tool, the hammer also has its upper quarter from the second longitudinal edge 103 towards the longitudinal center a slot recess 108 having an upper end surface 109 and a lower end surface 110. The end surfaces 109, 110 are spaced apart from one another, which corresponds approximately to the distance between the end surfaces 96,

97, but in any case is greater than the spacing between the end faces 78, 79 of the slot recess 77 of the crimping punch 46.

According to a further embodiment (see Fig. 1), the recess 5 in the lower front edge 101 can also be formed as an L-shaped or J-shaped recess so that only one hammer face 105 is then formed.

Core crimping punch 46, ejector 47, insulating crimping punch 48, and hammer 49 form an upper tool assembly 115, which is thus arranged in the receiving shaft 56 of the punch receiving means.

The crimping punch 46, with its one flat side, abuts the closure plate 55 on its inner side

25 facing the receiving shaft 56. On the free flat side of the crimping punch 46, the ejector 47 is adjacent with its one flat side. This is followed by a crimping punch 48, which is seated against the ejector 47 so that the ejector is longitudinally displaceable.

A hammer is applied against the free flat side of the crimping punch 48 with its flat side without a step formed. In the upper tool assembly 115, the individual tools 46, 47, 48, 49 are aligned such that their shape recesses 76, the ejector notch 84, the shape recesses 94 and the notch recesses 104 are respectively aligned. In addition, the individual tools 46, 47, 48, 49 are arranged so that the slot recesses 77, 87, 95 and 108 are arranged approximately in alignment with each other so that the plug 64 can pass through.

The upper tool assembly 115 thus disposed will be pushed from the open lower side of the receiving shaft 56 into the shaft until the step surface 107 abuts the lower edge of the bottom wall 51. In this position, the slot recesses 77,

87, 95 and 108 in alignment with the recesses 62, 63 of the punch receiving means 45, so that by inserting the plug 41, the upper tools of the upper tool assembly 115 will be held in shape in the punch receiving means 45. Due to the greater widths of the slot recesses 87, 95, 108 and the exact fit of the upper tool in terms of depth and width, in this pre-assembled upper tool arrangement, the ejector 47, the crimping punch 48 and the hammer are in the punch receiving means 45. 49 by a certain amount without clearance longitudinally displaceable in their longitudinal direction in the receiving shaft 56.

This arrangement forms the upper tool module 7 from the punch receiving means 45 and the bundled assembly 115 of the upper tool assembled into the punch receiving means 45.

The location of the slot recesses 22/22/95 and 108 in the upper tool parts 46, 47, 48, 49 is selected such that the upper front edges 72, 80 are arranged at the same level somewhat above the upper side of the side walls 52, 53 and the leading edges 90, 100 relative to each other and relative to the upper leading edges

the edges 72, 80 have been spaced deeper when the upper extreme surfaces of the slot recesses 22/22/95, 108 are in the assembled state of the upper tool module 2 abutting the plug 64. In this position, the lower front edges 73,

81, 91 of the crimping punch 46, the ejector 47 and the crimping punch 48 are in alignment with each other, with the lower leading edge 101

And / or the hammer faces 105 are arranged somewhat rearwardly in the direction of the punch receiving means 45.

The crimping punch 46 and ejector 47 have a longitudinal dimension h relative to which the longitudinal dimension of the crimping punch and the hammer 49 is somewhat smaller.

The bottom tool module 6 (see FIGS. 6 and 7) is in the form of a plug-in cassette with a cassette base body, the cassette base body being formed as a two-piece base plate 120 and a guide rail 121. and also for receiving the latching means, in particular the latching bolts 122 for latching a fixed bearing without play of the lower tool module 9 in the frame 2 of the press device 1.

The base plate 120 is formed essentially as a flat plate with a double stepped top side 123, a straight bottom side 124, a first side edge 125, a second side edge 126 as well as a first free end edge 127 and a second end edge 128 lying at the opposite end. the upper side 123 in advance from the free end edge 127 forms a first step 129 and a second step 130 with a support surface 131, the first step 129 having an insertion chamfer 132. The second side edge 126 is provided with a guide rail 121 whose upper side 135 follows the outline of the upper The guide rail 121 has a free side edge 136 which is spaced parallel to the first side edge 125 of the base plate, the distance of the first side edge 125 and the free side edge 136 corresponds to the distance of the side panels. edges 18 of the flat groove 16 in the foundation

30 so that the cassette base body is slidable into the flat groove 16 without play in the lateral direction.

According to another embodiment (see FIG. 1), both the side edge 125 and the free side edge 136 may have sliding lugs 141.

In the region between the first stage 129 and the second stage t

130 is approximately transversely centered with respect to the cassette base body in the longitudinal direction of the base plate 120 extending a longitudinal shaped recess 137 into which a latch 122 is resiliently rotatably mounted about an axis 138 that is adjacent to the first step 129. The latch 122 has a sliding surface 139 and a snap edge 140 that faces the abutment surface 131.

In the region between the second step 130 and the second leading edge 128, an L-shaped recess 142 is formed in the upper side 123, which on one side 15 is bounded by the inner side 136a of the guide rail 121 so that it forms in the cassette base body. As seen from above, the approximately square U-shaped recess. In the recess 142 a seating portion 143 displaceably displaceable in the longitudinal direction of the cassette base body ²⁰ is fastened to the inner side 136a by a screw 143a. The seating portion 143 has a plate shape and has an anti-rotation bar 143c towards the inside that engages a corresponding L-shaped recess 143d in the guide rail 121, thereby preventing rotation of the seating portion 25.

143 when tightening the screw 143a. The seating part 143 has a recess 144 in which the support means 145 is mounted in height.

The support means 145 is substantially L-shaped and has an insertion arm 146 and a support arm 147.

The upper side of the support arm 147 serves as a support surface for the contact area of the bead contact element to be machined.

Opposite to the precisely formed front side 143b of the abutment part 143, a lower tool 5 corresponding to the core crimping punch 46 and the insulating crimping punch 48 is mounted in the recess 142, which is known in each case with one core crimping zone and insulating crimping contact flange. The lower tool 150 has a correspondingly formed rear side to the stepped front side 143b, so that the lower tool 150 is positioned defined with respect to the inner side 136a. The dimensionally precise arrangement for receiving the lower tool 150 and with minimal tolerances extends from the free side edge 136 through a dimensionally precisely formed guide rail 121 to the base tool 150a 15 of the lower tool and thus to the anvil 150a of the lower part.

Opposite the second leading edge 128, the recess 142 is closed face-to-face with a knife holder 152 fixed by means of screws 152a, more precisely bolted. The knife holder 152 has a projecting and displaceable punching knife 153 which extends over its upper side over its upper side and transversely biased in its working direction 5. The punching knife 153 has a known cutting edge 154 which cooperates with a corresponding cutting edge 155 on the lower tool 150 and a second cutting blade. The cutting edges 154, 155 serve to separate the flange contact element from the support strip (not shown). The second cutting edge 156 and its cutting edge 157 serve for crushing as waste of the remaining support belt, the two cutting arrangements 154, 155 and 156, 157 respectively being arranged approximately at right angles to each other. The die cutter 153 has a control face 158 on its upper side which corresponds to the hammer face 105 of the hammer 49. After the knife holder 152 has been screwed on, the seat 143 will be moved in the direction of the knife holder 152 when the screw 143a is loosened. For example, the lower tool 150 is seated in the cassette base body without play in the longitudinal direction while still providing free vertical displacement of the knife 153.

The described arrangement of the cassette base body, the latch latch 122, the abutment member 143 with the support means 145, the lower tool 150 and the knife holder 152 with the punch knife 153 form the lower tool module 9 as snap-fit unit into the flat groove 16 of the base plate 1. in such a way that the abutment surface 131 abuts against the edge 40 of the anti-snap bracket and the snap-in latch 122 with its snap edge 140 on the chamfer 22 / whereby the bottom tool module 9 is precisely positioned in its longitudinal direction, i.e. and in its transverse θ direction, i.e. in the feeding direction 11.

The projections 166, 167 surround their inner sides 169, 170 a vertically extending U-shaped groove 171, the bottom of the groove 172 extending parallel to the second face 164 and slightly overhanging it. The protrusions 166, 167 are delimited in their longitudinal dimension by the leading edges 173, 174. Vertically in the middle have protrusions

166, 167 from the leading edges 173, 174 extending groove recesses 17 5, 176 with a U-shaped cross-section and in alignment with each other, which are bounded by the upper extreme edge 177 and the lower extreme edges 178 extending parallel thereto. .

Threaded holes 180 are formed at the vertically upper and vertically lower ends of the protrusions 166, 167 from the leading edges 173, 174.

Between the groove recess 175 of the first projection 166 and its leading edge 168, an open recess 181 with a semicircular cross-section is formed from the leading edge 173 into the interior of the groove 171, the bottom of the recess being slightly spaced from the groove bottom 172.

Opposite the rear first flat side 163, a guide plate 184 is positioned over the entire 25 vertical longitudinal dimension of the support member 160, which protrudes somewhat on the sides of the support member 160 so as to form sliding projections 185, 186 with which the tool head 6 is shaped. vertically displaceably mounted in a guide groove bounded by a flat groove 27 and grooved drive plates 30.

Around the center of the housing 268 is a hole 269 that receives a pin (not shown) on which the adjusting wheel 266 is rotatably mounted about a horizontal axis 26.

Against the lower leading edge 244 of the second push piece

222, a pressure plate 270 is seated, which is fixed by a screw 271.

···· · ·

The pressure plate 270 has grooves corresponding to the bottom 172 of the longitudinal edge 272, the longitudinal edge 273 lying on the opposite side, and two leading edges 274, which always closely coincide with the lateral edges 242 of the pressure member 222. so that between these overhangs 275 delimited by the longitudinal edge 272, a groove is formed for the ejection handle 86 of the ejector 47.

Thus, it is possible to adjust the stop of the first pusher 220 and thereby the vertical upper position of the punch 46 above the adjusting means 188 by rotating it, the upper projection 230 cooperating with the helical lower abutment surface 192.

The vertical upper stop for the crimping punch 48 and the hammer 49 relative to the crimping punch 46 represents the second pusher 222 together with the pusher plate 270, its vertical upper stop position being adjustable relative to the upper stop via the adjusting wedge 248, control pin 265 and adjusting wheel 266. The ejector control protrusion 86 can penetrate between the protrusions 275 of the pressure plate 270 and through the groove 251a and can cooperate with the circular cam 237 25 of the control lever 231. If the ejector 47 remains after crimping the crimped contact element, for example to clamp the crimped contact 6 or 48, in an elevated position relative to the flanging element

46, 48, then the control lever 221 is in the pivoted position 30 raised relative to the lower limit pivoted position, with the pin 239 somewhat protruding from the hole 238. On retraction of the tool head, for example, the free end of the pin 239 slides along the sliding surface and automatically moves the control lever back to its lower limit rotational position, thereby ejecting the ejector vertically downward relative to the flanging punches 46, 48 and thereby through its notch 84 The ejector releases the optionally crimped crimped contact element from the crimping punch 46, 48.

The second flat side 164 of the support member 160 together with the closing counterpart 210 and the lock / unlock button 201 form the receiving means for the upper tool module 2. Inserting the upper tool module 2 into the tool head 2 proceeds as follows:

First, the upper tool module 2 is mounted with its locking plate 55 forward on the other flat side 164, pressing the locking / unlocking button against the spring pressure of the spring 205. The closing walls 60, 61 of the locking plate 55 are displaced vertically downwards toward the closing the projections 212 of the closure flange 210 so that the closure wall 60 can extend between the closure projections 212. Then, the upper tool module 2 is moved vertically upward in the working direction 5 so that the closure wall 60 engages the top closure projection 212 and the closure wall 61 engages the bottom closure the protrusion 212 until the upper sides of the side walls 52, 52 engage the lower front edge 168 (see dashed mounting arrow in FIG. 1). In this position, the locking / unlocking button 201 is ejected to its starting position by means of the elastic pressure, thus automatically securing the upper tool module 2 in this vertical position.

Improved seating without play of the lower tool module is ensured at different manufacturing tolerances of the anti-snap arm

38. In addition, the curved formation of the snap edge 140 ensures a continuous line contact with the chamfer 22. Contact of the snap latch 122 with the chamfer corners is avoided.

In a crimping device of this type according to the present invention, it is particularly advantageous that the corresponding upper tool module 1 and the lower tool module 9 can each be pre-assembled and prepared together for a single press assembly and can be pre-prepared as replaceable modules for different sizes or types of crimped contact If necessary, they can be replaced in a simple manner with the built-in upper or lower tools by means of a replaceable module, whereby the use of assembly tools is avoided by the simple operation of a snap-in means for the tool modules. Only by pressing on the corresponding unlocking means are the tool modules replaceable with little force. Nevertheless, the advantages of the separate adjustment of the crimping punches by the adjusting means on the tool head and the adjusting wheel on the front of the tool head remain fully maintained. These adjusting means no longer have to be disassembled for the replacement of the tool module, so that the demanding dismantling and subsequent mounting of the adjusting means can be dispensed with.
