Description

[Technical field]

[0001] The present invention relates to a crimping pliers die intended for use in a crimping pliers. The crimping pliers die comprises two die halves, the crimping surfaces of which define a die receptacle into which a workpiece can be introduced, which is then crimped between the crimping surfaces of the die halves. For example, the crimping pliers die is used for crimping a workpiece, which is an end sleeve (with or without an insulating collar) having a cable arranged therein. Furthermore, the present invention relates to a crimping pliers comprising such a crimping pliers die. [Background technology]

[0002] EP 0 516 598 discloses a crimping pliers die having two die halves, each of which is fitted to a bearing eye of a pliers jaw of the crimping pliers. TurningThe die halves are pivotally supported on the plier jaws via pins so as to be pivotable about a pivot axis arranged perpendicular to the pivot plane of the plier jaws. The die halves each have a guide rod on one side of the die and a guide recess formed as a guide hole on the other side of one of the dies. The guide rod of the die halves is then slidably introduced in the direction of the crimping axis into the assigned guide hole of the other die halves, thereby forming an anti-rotation device, through which the two die halves are introduced relative to one another over the crimping stroke. In the relative position of the two die halves defined by the anti-rotation device, the two die halves can rotate together about a rotation axis extending coaxially to the crimping axis. Depending on the angle of rotation of the die half unit about this axis of rotation, the longitudinal axis of the die receiver defined by the two dies can then be oriented in a first pivot position, in which the die receiver is oriented in the longitudinal direction of the crimping pliers and extends in the plane of rotation of the pliers jaws, as well as in a second pivot position, in which the die receiver is oriented perpendicular to the plane of rotation of the pliers jaws. In the first pivot position, the workpiece can be introduced into the crimping pliers and its die receiver from the front, whereas in the second pivot position, the workpiece can be introduced laterally into the die receiver.

The object of the invention is therefore to propose a crimping pliers with a correspondingly improved crimping pliers die. [Means for solving the problem]

[0005] The object of the present invention is achieved by the features of the independent claims. Further preferred embodiments of the invention can be read from the dependent claims. Effect of the Invention

[0006] The invention proposes a crimping pliers die with two die halves. Both die halves are guided relative to each other over the crimping stroke by means of a guide. Each die halve has one die half, which forms a crimping surface which directly interacts with the workpiece to apply a crimping force thereto. In the crimping pliers die of the invention, the guide comprises a guide rod which is held in at least one die half. This guide rod is introduced into a guide recess in the other die half. The guide rod and the guide recess can have any cross section, as long as they ensure longitudinal guidance over the crimping stroke. Preferably the guide rod has a (part) circular guide cross section.

[0007] It is also possible to provide two guide rods which are then inserted into the corresponding guide recesses. Here, both guide rods can be provided on one die half and, in turn, both guide recesses are arranged on the other die half. However, it is also possible for each die half to be provided with a guide rod and a guide recess.

[0008] In EP 0 516 598, the die halves are formed with a large crimping surface. This crimping surface is formed in a continuous manner according to EP 0 516 598. The continuous crimping surface of one die half of EP 0 516 598 forms a convex surface, while the other die half of EP 0 516 598 forms a concave surface. In contrast, the invention proposes to use another type of die half, for example corresponding to EP 0 516 598, in the die half unit with guide, that is to say die halves each having a number of ribs. The ribs of the die halves then engage with one another with a varying engagement progression over the crimping stroke. In this case, the crimping surface of the die half is formed by the front faces of the ribs. This type of die does not result in a consistent crimping of the large surface of the workpiece between the die halves, but rather the crimping takes place in a number of spaced apart partial areas in the front area of ​​the spaced apart ribs of the die halves. The use of such die halves has proven to be advantageous in the case of special types of workpieces, in particular for crimping end sleeves of wires by cables. Such die halves with interlocking ribs are known, for example, from the Applicant's tool bearing the designation "CS10-AE22" or from EP-A-3179580, US-A-4283933 and US-A-6151950. Surprisingly, it has been found that the use of such known die halves with interlocking ribs can also be used for crimping pliers dies with guides for the die half units, as is known, for example, from EP-A-0516598.

[0009] In EP 0 516 598, the die half comprises a base plate extending therefrom towards the other die half. In EP 0 516 598, the die plate has guide recesses on one side of the die, and in EP 0 516 598, a guide rod is fixed to the base plate on the other side of the die profile. In a first variant of the invention, this is deviated from by the guide rod being formed by a thickened end region of at least one rib of the die half. This connection of the guide rod to the at least one rib of the die half can be carried out alternatively or cumulatively for the connection to the base plate. However, the formation of the guide rod by a thickened end region of at least one rib results in a particularly compact design. A simplified manufacture is also possible, since the guide rod can be a component which fits into the at least one rib. This reduces the assembly complexity and allows for a wide variety of constructions of the crimping pliers dies. It is also possible that the stiffness is reduced. Instead, the guide rod is connected to the plate-like base body via at least one part of the extension of the rib(s) in the direction of the crimping axis, so that a particularly rigid support can result. As a result, the guide rod is not held freely cantilevered on the base body, which possibly increases the precision of the guide and increases its mechanical strength.

[0010] Alternatively or cumulatively, in a second variant of the invention, the guide recess can be formed by a guide recess area, or a connecting area, arranged in the end region of at least one rib and preferably connecting the end regions of two ribs of one of the dies. In this case, the guide recess area forms at least a cylindrical segment-shaped guide surface and a guide recess defined by the guide surface, which is open at the edge of the cross section, i.e. in the direction of the space between the two ribs. The guide recess area then has a cylindrical segment-shaped guide surface into which the guide rod is inserted. Here, the cylindrical segment has a cylindrical segment angle of 180° or more (preferably 200° or more, 220° or more, 240° or more, 260° or more, 280° or more), which can have the consequence that the cylindrical segment-shaped guide surface can be used to provide a support in orthogonal directions in a plane transverse to the guide axis. By connecting the guide recess area to the two ribs, a very rigid support can be ensured.

[0011] The die halves (and also the other components of the crimping pliers die) can be manufactured using any manufacturing method, for example casting, injection molding and / or material removal or milling manufacturing methods. In a particular proposal of the invention, the die halves are formed as powder injection molded parts. Powder injection molding, also called PIM process (abbreviation of power injection molding) or MIM process (abbreviation of metal injection molding), is the main molding process for manufacturing metal parts. In powder injection molding, fine metal powder is mixed with an organic binder and molded in an injection molding machine. The organic binder is then removed and the part is sintered at high temperatures in a furnace. Optionally, post-processing can be carried out after the manufacturing in the injection molding process(es). The powder injection molding process has been shown to be advantageous for the manufacturing of the die halves and for the generation of complex shapes of multiple ribs and / or guides arranged parallel to one another.

[0012] In a further proposal of the invention, at least one die half has a bearing part, by means of which the die half can be pivotally mounted to the assigned pliers jaw. In this case, the mounting takes place by means of a pivot axis arranged perpendicular to the pivot plane of the pliers jaw. Turning By utilizing the degree of freedom set by the axis, alignment of the die halves with respect to one another at the pliers jaws can be achieved by the guide rod being arranged coaxially with respect to the guide recesses, whereby insertion of the die halves into one another is possible, on the one hand, by the guide rod entering the guide recesses and, optionally, by the engagement of the ribs into one another, on the other hand.

[0013] The bearing part essentially conforms to EP 0 516 598 and is received in the bearing eye of the pliers jaw. Turning The bearing body is designed as a pin. A particularly simple assembly results from the reduction in the necessary parts when the bearing part has a bearing body, due to the further proposal of the invention. The bearing body can in this case have a cylindrical segment-shaped guide surface with a guide diameter. Furthermore, the bearing body has an insertion surface. In the region of the insertion surface, the extension of the bearing body is smaller than the guide diameter. When the bearing body is then to be inserted through the edge opening of the edged bearing eye in the cross section of the pliers jaws, the bearing body of the bearing part rotates so that the bearing body can be inserted through the edge opening into the bearing eye due to its smaller extension in the region of the insertion surface. In that way, when the bearing body is in the bearing eye, the larger guide of the cylindrical segment-shaped guide surface is eliminated. The bearing body rotates so that the guide diameter acts such that slipping out of the edge opening of the bearing body is no longer possible. For this purpose, the edge opening of the bearing eye of the pliers jaw is smaller than the guide diameter and has an extension in the insertion face area that is greater than the extension of the bearing body.

[0014] For the formation of the crimping pliers die, the die half unit may also form the bearing part or have a holder that may hold the bearing part. For this embodiment, the die half rotate It is journalled to the holder via a bearing. rotate The bearing has an axis of rotation oriented parallel to the guide axis of the guide rod and / or the guide recess, whereby the axis of rotation extends parallel or coaxially to the guide axis of the guide. The axis of rotation may coincide with the crimping axis of the crimping pliers. rotate By means of the bearings, it can be ensured that there is simultaneous rotation relative to the pliers jaws of the die half units so that the workpiece can be inserted into the die receptacle in various orientations, for example allowing insertion of the workpiece from the front or from the side.

[0015] It is also possible for a locking or interlocking device to be arranged between the holder and the die half, which can then lock or interlock the die half at a predefined relative rotation angle about the rotation axis between the holder and the die half, whereby the locking or interlocking device can ensure the working position of the crimping pliers die. Here, the locking can be released by the user applying a sufficiently large rotation force about the rotation axis, whereas the locking cannot be released by merely applying a torque about the rotation axis, but rather an unlocking element must be additionally manually actuated.

[0016] In this case, the holder and the die surface can be provided with a guide surface, which is oriented perpendicular to the axis of rotation, into which the holder and the die surface are inserted facing each other during rotation about the axis of rotation. On the other hand, the support of the pressing force between the holder and the die half can also be provided via the guide surface. The guide surface in this case has a recess, into which a locking or interlocking element is arranged which is then pressurized by an applied spring. The other guide surface then comprises a locking or interlocking recess. At a predefined relative rotation angle with respect to the holder of the die half, the locking or interlocking element is arranged (at least partially) in the assigned locking or interlocking recess, whereby the locking or interlocking is provided. In this way, a structurally simple but reliable locking or interlocking can be provided.

[0017] fundamentally rotate The bearings can be optionally formed for rotatable bearing of the carrier against one of the dies. rotate The holder has a bearing projection for forming the bearing. The bearing projection is oriented parallel to the guide axis of the guide rod and / or the guide recess of one of the die units. rotate The die half has an axial fixing element extending through the bearing bore. The material area of ​​the die half can then be clamped between the substrate or carrier and the axial fixing element, whereby the bearing projections are fixed to the die half. rotate The bearing projection is prevented from escaping from the bearing hole. For example, one of the dies has a side slit between the front surface facing the holder and the crimping surface. The end of the bearing projection has a ring groove. rotate When inserted into the bearing bore, the ring groove on the end face of the bearing projection can be accessed via the side slit, and an axial fixing element formed as a fixing ring can be introduced through the side slit and snaps into the ring groove.

[0018] In some embodiments it may be desirable to provide the crimping pliers or the crimping pliers dies with an insertion stop, via which the insertion support of the workpiece into the die receiver is provided. Preferably, how deeply the workpiece can be inserted in the longitudinal direction of the workpiece into the die receiver in the longitudinal direction of the die receiver is set via the insertion stop. In the inventive proposal, the insertion stop is provided in the die half unit, which can also be arranged in or formed integrally with the die half. This can be done, for example, rotate It is advantageous when the die half is rotatably supported relative to the holder via a bearing about an axis of rotation oriented parallel to the crimping axis, When the relative rotation angle between the holder and the die half is changed, in this embodiment the insertion stop is rotated together, Which has the advantage that the insertion stop can be used independently of the relative rotation angle set and used by the user.

[0019] The invention includes embodiments in which only one insertion stop is arranged relative to one of the die half units or die half in a fixed position. The insertion stop may also be configurable. In a special embodiment of the crimping pliers die a stop body, in particular a stop disk, is provided. When a stop disk is referred to below, it may be any other rotatable stop body (or vice versa). The stop body may be a stop body rotate The stop body is journalled on one side of the die so as to be rotatable about the stop body rotation axis via a bearing. The stop body rotation axis is oriented parallel to the longitudinal axis or the receiving axis of the die receiver. The stop body has a number of lead-in stops, which are adapted to different sizes and axial lengths of different workpieces, for example wire end sleeves. The different lead-in stops can thereby set different lead-in depths for the insertion depth of the workpiece into the die receiver. The lead-in stops are distributed (evenly or unevenly) around the circumference and the stop body rotation axis. By rotating the stop body about the stop body rotation axis, different insertion stops can be acted upon, so that by rotating the stop body, the user can adapt the crimping pliers die, i.e. by adjusting the insertion depth, to different workpieces, in particular wire end sleeves of different types or sizes.

[0020] The rotational position of the stop can be fixed by frictional engagement or in another manner. In an embodiment of the crimping pliers die, a stop locking device is provided, which locks the stop to one of the dies at a given rotational angle of the stop, thereby fixing the operating position of the stop.

[0021] There are various possibilities for the embodiment of the stop-retaining or locking device. In the proposed invention, the stop and the die half each have a stop guide surface. The stop guide surface is oriented perpendicular to the stop rotation axis. The stop and the die half are inserted relative to each other during rotation about the stop rotation axis. The stop guide surface then has a recess, into which a spring-loaded stop-retaining or locking element is arranged. The other stop guide surface has a number of stop-retaining or locking recesses, into which the stop-retaining or locking element is arranged at least partially for the purpose of locking or locking, at a defined relative stop rotation angle, in which the insertion stop assigned to the stop rotation angle is arranged in the correct position relative to the die receiver. In this way, the operating position of the stop set by the user is fixed.

[0022] Stop body rotate There are many possibilities for the type of bearing configuration. In a possible embodiment, it is proposed that one of the dies has a stop bearing projection. This stop bearing projection is connected to the stop of the stop. rotate On the side of the stop opposite the die half, the stop bearing projection has an axial fixing element, which may be a fixing ring received in a ring groove of the stop bearing projection. In this configuration, the stop can be axially gripped between the base of the die half and the axial fixing element, thereby providing a fixation of the stop bearing projection against escape from the stop.

[0023] In the crimping pliers die, the die halves can be formed in different ways. The differences can relate on the one hand to the design of the die contour and the crimping surface, but also from this the design criteria of the guides or further elements or die halves can deviate from one another. By way of non-limiting example only, a die half can have two guide rods, which die half does not form a guide recess and thus A die half unit may only have a guide recess, but in a special embodiment of the invention, both die half units, both bearing parts and / or both die halves are formed identically, which reduces the variety of structures, reduces manufacturing costs, ensures more interchangeability and saves stockpiling.

[0024] A further solution of the problem according to the invention shows crimping pliers, in whose pliers jaws a die half unit of a crimping pliers die is held, as explained above.

[0025] Basically the crimping pliers die can be used for any design of crimping pliers, for example in the following respects: -Actuating kinematics, - Equipped with an electronic unit, - integration of sensors for detecting the crimping path and / or the crimping force, - Forced lock, -Possibility for replacement of the crimping pliers dies, -Ratchet drive gear, - allowing various crimping stages by dividing the overall crimping stroke into at least two partial crimping strokes with assigned closing movements of the hand lever and then opening and closing the hand lever again for the next partial crimping stroke, etc.

[0026] In an embodiment of the present invention, at least one die half unit is forced into the crimping pliers. distance Support is provided through compensation elements. Such forces distance The compensating element expediently provides flexibility in the path of the actuation force applied by the user to the hand levers of the crimping pliers to the pliers jaws and the die half units. This flexibility can be utilized so that the range of possible shapes of workpieces that can be crimped with the crimping pliers and their die half units can be expanded. Essentially, when the crimping pliers are designed for crimping workpieces of relatively small shapes, crimping with the crimping pliers and their die half units of relatively large shapes of workpieces results in the required crimping force already occurring before the hand levers are completely closed. Force distance Without the compensating element, the closed position of the hand lever cannot be reached. However, if a force lock is also used in the crimping pliers, it is absolutely necessary that the closed position be reached in order to reopen the crimping pliers. distance When using compensation elements, a stronger actuation force is applied to the crimping pliers. distance This results in a flexible compromise of the compensating element, which allows a complete closing of the hand lever, with the result that a reopening of the hand lever can also be permitted by the positive lock. distance Possible configurations of the compensation element are known, for example, from EP 3012923 B1 or from EP 0732779 B1, EP 0158611 B1, DE 3109289 B1, DE Utility Model 202012102561 B1, DE Utility Model 202009005811 B1, DE 102013100801 B1 and EP 2905848 B1. distance See Compensation Factors.

[0034] In the description of the drawings, the same reference numbers are used in part for components that are identical or similar in terms of shape and / or function, and these components may also be distinguished by additional letters a, b, .... Components with or without these additional letters are then associated and may thereby refer to such component, several components, or all components.

[0035] 1 shows in a spatially exploded view a crimping pliers die 1. The crimping pliers die 1 comprises an upper die half 2 and a lower die half 3, which are made identically, so that the following description thereof relates preferentially to the die half 2, and the same applies to the other die half 3.

[0036] The die half unit 2 has a holder 4 and a die half 5 .

[0037] The holding body comprises a bearing body 7 and a bearing part 6 with stops 8, 9 formed here as webs 10, 11 arranged on either side of the bearing body 7. The bearing body 7 and the bearing part 6 with the webs 10, 11 are arranged on the side of the holding body 4 opposite the die half 5.

[0038] On its side facing the die half 5, the carrier 4 forms a guide surface 12. From the guide surface 12 emerges at least one recess 13, 14, here formed as a blind hole 15, 16. At the base of the recess 14 there is a spring 17, via which a locking element 18, here a locking ball 19, is supported. Depending on the installation situation it is also possible for the spring 17 with the locking element 18 to be arranged in the further recess 13 or for a spring with an assigned locking element to be assigned in both recesses 13, 14.

[0039] The bearing body 7 comprises a cylindrical segment-shaped guide surface 20 and an insertion surface 21 which can be, for example, a flat 22 .

[0040] The die half 5 is provided with a guide surface 23 on its side facing the holder 4. In the assembled state, the guide surface 23 of the die half 5 rests against the guide surface 12 of the holder 4, via which the crimping force between the die half 5 and the holder 4 is also supported. On the other hand, the guide surfaces 12, 23 ensure guiding during the relative rotation of the die half 5 with respect to the holder 4, which will be described below, while the guide surfaces 12, 23 ensure the desired orientation of the die half 5 with respect to the holder 4 (preferably in the direction of the crimping axis 105) independently of this relative rotation.

[0041] From the guide surface 23 of the die half 5 emerge locking recesses 24a, 24b.... The locking recesses 24 are formed as blind or through holes in a base plate 25 of the die half 5. For locking the relative rotation angle between the holder 4 and the die half 5, a locking element 18 is pressed by a spring 17 from the holder 4 into the locking recess 24 of the die half 5 and can penetrate (at least partially) into the locking recess 24, whereby the relative rotation angle between the holder 4 and the die half 5 is fixed.

[0042] From the base plate 26 of the carrier 4 extends a bearing lug 27 which is formed here as an axle journal and which has an annular groove 29 in its end region facing away from the base plate 26. In the assembled state, the bearing lug 27 is fitted to the die half 5 of the die half 5. rotate It has a seat in a bearing bore 30. In the assembled state, the bearing lug 27 extends as far as a side slit 31 in the die half 5. Through the slit 31 the ring groove 29 of the bearing lug 27 is accessible from the outside, so that the design of the fixing element 32 as a fixing ring 33 allows the axial fixing element 32, here a fixing ring 33, to be connected with the bearing lug 27 through the side slit 31, by the fixing ring 33 fitting into the ring groove 29. In this way the bearing lug 27 of the holder 4 prevents the die half 5 from slipping out again.

[0043] The bearing projection 27 of the holder 4 is received by rotate In the bearing hole 30 rotate The bearing 34 is molded. rotate The bearings 34 allow relative rotation of the die half 5 with respect to the holder 4 about a rotation axis 35 which is oriented parallel or coaxially to the crimping axis 105. For various relative rotation angles between the holder 4 and the die half 5 about the rotation axis 35, fixing can be effected by the entry of the locking elements 19 into the locking recesses 24a, 24b, ..., whereby a locking device 36 is formed.

[0044] The die half 5 comprises a plurality of plate-like ribs 37a, 37b, ... which are arranged parallel and at equal intervals with respect to one another. The ribs 37 extend perpendicular to the substrate 25 of the die half 5. The ribs 37 extend parallel to the rotation axis 5 and the crimping axis 105. The spacing between the ribs 37a, 37b, ... is slightly greater than the thickness of the ribs 37a, 37b, .... The ribs 37a, 37b, ... all have the same thickness. The ribs 37a, 37b, ... of both die halves 5 are inserted into one another. , whereby the ribs 37 of the die halves 5 of one die half 2 are arranged in the gaps between the ribs 37 of the die halves 5 of the other die half 3. Preferably, the ribs 37 of the die halves 5 of the die half 2, 3 abut as closely as possible, but with little friction against each other, so that there can be an intermediate or clearance fit here. A relative movement of the ribs 37 is thereby possible in the direction of the crimping axis 105 and the rotation axis 35. In the direction perpendicular to the extension plane of the ribs 37, possibly small play occurs due to the relative movement of the holders 4 of the die halves 2, 3.

[0045] If the view is directed towards the die receiver 38 formed by the die half 5, the ribs 37 are essentially formed corresponding to a right-angled triangle, where the sides defined by the right angles of the triangle are alternately connected to the base plate 25 of the die half 5, which results in the crimping surfaces 39, 40 of adjacent ribs 37 formed by the ribs 37 forming a kind of V-shape or right angle. The crimping surfaces 39, 40 of both die halves 5 of the die half 2, 3 define a square, rectangular or rhombus cross-sectional profile of the die receiver 38 seen in FIG. 2. Here, by the relative movement of the die halves 2, 3 in the direction of the crimping axis 105, the size of the die receiver 38 can be reduced over the crimping stroke, but still the square, rectangular or rhombus cross-sectional profile remains maintained.

[0046] The die (except for the side having the crimping faces 39 , 40 ) has an essentially rectangular parallelepiped external shape due to the formation of a die receptacle 38 , which is open in the gap regions between the ribs 37 .

[0047] The (preferably central) rib 37 is formed by strip-like or plate-like extensions 41 and end portions 42 extending over the rectangular prism-shaped exterior. Thick bulging part Extends with 42. Thick bulging part 42 form a guide rod 43 which joins the rib 37 over an extension 41 over the entire extent of the assigned rib 37 in the direction of the crimping axis 105. Thick bulging part42 is kept the same in the direction of the crimping axis 105 and has in the region of the extension 41 a cross section which is formed by two guide surfaces arranged parallel to one another. Thick bulging part In the region of 42 the cross section is formed part-circular, so that the guide rod 43 forms a guide surface 44 in the form of a cylindrical segment.

[0048] On opposite sides, the two ribs 37, which directly abut or define the ribs 37 forming the guide surfaces 43, form a connection region or guide recess region 45 arranged on the outside of the rectangular parallelepiped shape. The guide recess region 45 comprises two plate- or strip-shaped extensions 46, 47 as well as a guide recess portion 48. The extensions 46, 47 form the guide surfaces arranged parallel to one another, the guide recess portion forming a cylindrical segment-shaped guide surface 49 in the interior. The guide surface 49 forms a guide recess 50 or a (open-edged) guide hole. The guide recess region 45 extends over the entire extension of the assigned rib 37 in the direction of the crimping axis 105 and has a full extension over the constant cross section.

[0049] Due to the shaping of the guide 51, the assembled crimping pliers die 1 receives the guide rod 43 of the die half 5 of one die half unit 2 in the guide recess 50 of the die half 5 of the other die half unit 3 and vice versa. Using the guide 51 it is ensured that: - both die halves 5 of the units 2, 3 are rotated together about the axis of rotation 35, the displacement of the die halves 5 of the die half units 2, 3 across the crimping axis 105 and in the main extension plane of the ribs 37 is limited or interrupted, and / or support for the die halves 5 of the die half units 2, 3 is provided in a direction perpendicular to the main extension of the ribs 37;

[0050] Optionally, at least one die half 5 of the crimping pliers die 1 is used here as a stop plate. The stop body 52 may be formed by a stop body. rotate The die is supported rotatably on the base or rib 37 of the die half 5 via a bearing 53. rotate The bearing 53 has a stop rotation axis 54 oriented perpendicular to the main extension plane of the rib 37. rotate The bearing 53 is molded out of the base or rib 37 of the die half 5 with a stop bearing projection 55 having a stop ring groove 56 on its end face. rotate In the assembled state, the stop bearing projection 55 of the die half 5 is fitted to the stop 52 of the stop rotate 2 and 3. The stop 52 extends through the bearing bore 57. The stop 52 is axially fixed to the die half 5 via an axial stop fastening element 58 (here a stop fastening ring 59, which rests in the stop ring groove 56), where the stop 52 is axially gripped between the stop fastening element 58 and the base or rib 37 of the die half 5.

[0051] The stop bodies 52 are provided with lead-in stops 60a, 60b distributed around the stop body rotation axis 54, which can be brought into the working position at various relative rotation angles of the stop body 52 about the stop body rotation axis 54 relative to the die half 5, in which they respectively set an insertion position in the die receiver 38 for the insertion of the workpiece. Here, the lead-in stops 60a, 60b can be provided with various passage recesses as shown, which can be formed conically, for example, on the side opposite the die half 5, or can also have an elongated cross section with an oblique guide surface deviating from a circular cross section. It is also possible for the individual insertion stops 60 to have various stop positions in terms of the stop body rotation axis 54, which results in that for the various insertion stops 60, the end sleeve of the wire is inserted to various depths in the die receiver 38 in their working positions. The various insertion positions ensure, for example, that the inner end region of the end sleeve of the wire is in a defined position in the die receiver 38, in particular in a defined relative position to the rib 37.

[0052] In the alternatively illustrated embodiment, the crimping pliers die 1 comprises a stop body locking device 61. Here, the die half 5 comprises at its bottom a recess 62 in which a spring 63 and, via the spring 63, a stop body locking element 64 in the form of a locking ball 65 are supported. On the side facing the die half 5, the stop body 52 comprises a number of circumferentially distributed stop body locking recesses 66, in which the stop body locking elements 64 can be locked in the various operating positions of the insertion stop 60.

[0053] Figures 4 and 5 show a crimping pliers 67 (without the front fixed pliers part plate) with the die halves 2, 3 of the crimping pliers die 1 attached to the pliers jaws 68, 69. Figure 5 now shows part IV of the connection area of ​​the crimping pliers die 1 with the pliers jaws 68, 69. The pliers jaws 68, 69 each form one bearing eye 70 which, together with the bearing bodies 7 of the die halves 2, 3, rotateThe bearing 71 is molded with a rotation axis 72, which is oriented perpendicular to the plane of the drawing in Figures 4 and 5 and perpendicular to the swivel plane of the pliers jaws 68, 69. The bearing eye 70 comprises a bearing hole 73 with an edge opening 74, for which the bearing hole 73 is formed in the form of a cylindrical segment with a segment angle of more than 180°, for example between 190° and 240°. The lateral boundaries 75, 76 of the edge opening 74 therefore have a distance that is smaller than the guide diameter of the bearing hole 73. To insert the bearing body 7 of the bearing part 6 into the bearing eye 70, the bearing body 7 of the die half unit 2 (without the further die half unit 3 held therein) is rotated perpendicular to the swivel plane of the pliers jaws 68, 69 relative to the position in Figure 5 so that the bearing body 7 can pass through the edge opening 74 with the insertion surface 21, here the flat 22. When the bearing body 7 is in the bearing eye 70, it is pivoted perpendicularly to the pivoting plane of the pliers jaws 68, 69 so that the insertion surface 21 is located inside the bearing eye 70. The larger guide diameter of the cylindrical segment-like guide surface 20 of the bearing body 7 prevents the bearing body 7 from escaping again from the bearing eye 70 due to this rotation angle and the rotation angle passed during the adjacent crimping stroke. Preferably, the rotation angle of the bearing body 7, by which it can be inserted into and escaped from the bearing eye 70, is determined by the crimping pliers dummy to which this rotation angle is held. 11. It is selected such that this rotation angle is only possible for the crimping pliers 67 which are at least partially disassembled, and cannot be reached for the assembled crimping pliers 67 having the ... assembled therewith.

[0054] 6 shows in a spatially exploded view a possible embodiment of a crimping pliers 67 in which the crimping pliers die 1 can be used. The crimping pliers comprises a fixed pliers part 67.

TurningThe fixed pliers part 77 is pivotally supported by a pin 82. Here, the fixed pin 82 can alternatively be arranged in the region of a first longitudinal extension 83 or a second longitudinal extension 84 of the elastic pliers jaws 81. The first longitudinal extension can, for example, correspond to approximately half the longitudinal extension of the elastic pliers jaws 81, and the second longitudinal extension 84 can, for example, correspond to approximately half the longitudinal extension of the elastic pliers jaws 81. Turning The elastic pliers jaws 81 can be arranged at a distance of one third to one quarter of the distance from the pin 80. The elastic pliers jaws 81 thereby comprise a freely projecting pliers jaw portion 85 in which, in its free end region, the bearing eye 70 is arranged. The elasticity of the material, in particular the stiffness and / or the cross section and the second moment of area of ​​the elastic pliers jaws 81 are selected such that, in the presence of a sufficiently large crimping force, both an elastic bending or escape movement of the elastic pliers jaws 81 and that of the bearing eye 70 can occur. In this way, the force distance A compensation element 86 is provided.

[0055] The movable hand lever 87 is rotate Through bearing 88 Turning The movable pliers jaw 90 is articulated by a pin 89. rotate Through bearing 91 Turning The movable hand lever 87 is pivotally supported by the fixed pliers jaw 77 via a pin 92. rotate Even through bearing 93 Turning A pin 94 connects the pressure lever 95 to the end region of the pressure lever 95. rotate Through bearing 96 Turning The movable pliers jaw 90 is articulated to the fixed pliers part 77 by a pin 97. An opening spring 104 acts between the movable pliers jaw 90 and the resilient pliers jaw 81. The movable hand lever 87, the pressure lever 95 and the articulation of the movable hand lever 87 to the movable pliers jaw 90 form a toggle lever drive 98.

The movable pliers jaw 90 and the elastic pliers jaw 81 each form a bearing eye 70 in the end region of the scissor jaw area, in which the bearing body 7 of the die half units 2, 3 of the crimping pliers die 1 is mounted.

[0056] In Figures 6 and 7 it can be seen that the crimping pliers 87 are formed in a panel construction and that a number of individual panels may be formed.

[0057] The crimping pliers 67 also comprise a force lock 100 in the illustrated embodiment. The force lock 100 prevents the performance of a crimping stroke from being possible with more than one partial crimping stage, after each partial crimping stage opening of the crimping pliers 67 is prevented by the force lock 100. Opening of the crimping pliers 67 is instead only possible due to the force lock 100 when the crimping stroke and therewith all partial crimping stages have been completely performed. In the illustrated embodiment, the force lock 100 comprises an external gearing 101 of the pressure lever 95, a pawl 102 and a pawl spring 103.
