Definitions

  • the invention relates to crimping pliers in which the jaws of the pliers are moved relative to one another by manual actuation of hand levers via a drive mechanism, such as a toggle lever drive.
  • a drive mechanism such as a toggle lever drive.
  • die-half units held on the pliers jaws can be brought closer together via a crimping stroke, whereby a workpiece can be crimped between the die-half units.
  • the workpiece is, for example, a plug with an end region of a cable with at least one electrical conductor arranged therein. Both the mechanical connection between the plug and the cable and the electrical connection of the plug to the at least one electrical conductor are to be ensured by means of the crimping.
  • the crimping pliers according to the invention can be used to produce any desired crimping contour. In particular, a trapezoidal or square crimp is produced using the crimping tool.
  • the invention also relates to a die-half unit intended for a crimping tool. Finally, the invention also relates to a method for assembling a die formed with two die half parts to form a crimping tool.
  • EP 0 516 598 B1 describes that it can be advantageous if a workpiece can be inserted into the die of a crimping tool either from the side or from the front.
  • EP 0 516 598 B1 proposes that the die halves of the die half units be mounted on the associated pliers jaws so that they can rotate about the crimping axis, so that the die halves can be pivoted about the crimping axis in such a way that the receptacle formed by the die halves for the Workpiece is oriented either sideways or frontally.
  • the die half units each have a bearing body, which here consists of a U-shaped insert made of plastic.
  • the side legs of the U-shaped bearing body have half-shell-shaped bearing surfaces on the side facing one another, which together form a bearing eye.
  • a pivot is mounted, which is formed by the die half on the side facing away from the die contour.
  • the U-shaped side legs of the bearing bodies have cylindrical axle stubs that are aligned coaxially with one another.
  • the bearing bodies are inserted into the space between the plates of a pair of pliers.
  • the stub axles enter corresponding bearing bores in the plates of the pliers jaws, whereby the bearing bodies are mounted pivotably about pivot axes which are oriented vertically to the plane of the pliers head, relative to the pliers jaw.
  • the die halves are assembled on the bearing bodies by inserting the pivot pin into the bearing eye of the bearing body.
  • the die half is secured to the bearing body by screwing a screw with a washer into the free end face of the pivot pin, whereby the bearing body is caught between the washer and a base body of the die half in the vicinity of the bearing eye.
  • a rotary bearing by means of which the die half is mounted so as to be rotatable about the crimping axis relative to the bearing body, is provided by receiving the pivot pin in the bearing eye.
  • DE 197 28 685 A1 additionally proposes equipping the rotary bearing, via which the die half is rotatably mounted with respect to the bearing body, with a locking device so that locking of the die halves is possible on the one hand for the frontal alignment and on the other hand for the lateral alignment.
  • the locking device has a spring clip which is held by the bearing body and which interacts with a longitudinal groove of the pivot for locking with a locking lug.
  • WO 2019/105703 A1 and WO 2019/105704 A1 each show the preamble of claim 1 and together disclose die half units pivotable about the crimping axis relative to the pliers jaws.
  • the die halves are not guided relative to one another by receiving guide pins in guide bores. Rather, the die halves have die half plate bodies which are oriented parallel to one another and engage in one another, thus ensuring guidance transversely to the die plate bodies. Additional guidance is provided by guide plates whose surface normals extend parallel to the die plate bodies.
  • the two die halves are designed identically.
  • a base body of the die half has a bore in which a bearing pin of the bearing body is rotatably mounted.
  • the pivot pin of the bearing body is axially secured in the bore of the die half by means of a U-shaped plug-in part which can be inserted through a lateral recess in the die half.
  • the plug-in part In the assembled position, the plug-in part is secured in the direction of the crimping axis in the recess of the die half.
  • Side legs of the U-shaped plug-in part engage in a corresponding groove of the pivot pin, so that the pivot pin is secured axially in the die half.
  • the bottom of the groove of the pivot can be non-circular, so that the rotational position of the die half can be locked around the pivot bearing and around the crimping axis.
  • the plug-in part To disassemble the die half from the bearing body, the plug-in part must be pulled out while the same is resiliently widened, for which purpose the plug-in part must be gripped in the area of the base leg of the U using pliers, or a pointed tool must be used to push out the end faces of the side legs of the U-shaped part Plug part must be applied.
  • the bearing body has a pivot pin oriented transversely to the crimping axis with guide jaws formed at the end.
  • the pivot pin is accommodated in a bearing mount of the pliers jaw, which extends beyond half the circumference of the pivot pin in order to provide a captive mounting of the pivot pin.
  • the crimping tool according to the invention has a die which is used to crimp the workpiece.
  • the die has two die halves units, each attached to an associated Jaw of the crimping tool are stored.
  • At least one die half assembly has a die half and a bearing body.
  • the die half forms a die half contour that interacts with the workpiece during the crimping process.
  • the bearing body is mounted in a bearing seat of the associated pincer jaw, with which a die half bearing is formed.
  • the die half bearing is intended to enable the die half unit to be detachably mounted on the pliers jaw, with which the die half is also to be held captively on the pliers jaw.
  • the die half bearing is used to transfer the crimping force generated by the actuation of the hand lever and possibly increased by the drive mechanism from the jaw of the pliers to the die half unit, in which case the die half can then be pressed against the lateral surface of the workpiece with the crimping force.
  • the die half bearing provides an unlimited or limited degree of pivoting freedom with a pivot axis, the pivot axis being oriented vertical to the plane of the tong head.
  • This pivoting degree of freedom allows the die half unit to be pivoted relative to the pliers jaw for a compensating movement that is required over the crimping stroke of the pliers jaws, since the relative angle of the pliers jaws changes as a result of the pivoting of the pliers jaws.
  • the die half is mounted via a rotary bearing so that it can rotate about a crimping axis relative to the bearing body.
  • the orientation of the die half can be changed as required, so that, for example, the workpiece can be inserted into the die laterally or frontally (or with any other orientation) and/or can be crimped in such an orientation during the crimping process.
  • the crimping pliers can also be configured, for example, in accordance with the embodiments mentioned at the outset.
  • the bearing body of the die half unit can be assembled and disassembled with the bearing mount of the pliers jaw without tools and can therefore be assembled and disassembled solely by hand.
  • the bearing body and the bearing mount are connected to one another via a locking device.
  • the bearing body is not “absolutely” fixed relative to the bearing mount. Rather, this merely restricts or eliminates at least one degree of freedom (in particular the assembly and/or disassembly degree of freedom) between the bearing body and the bearing mount.
  • the locking device preferably ensures the degree of freedom of pivoting of the bearing body in relation to the bearing mount about an axis of rotation which is oriented vertically to the plane of the pliers head.
  • the locking device is a "locking device".
  • a latching device is formed between two components, here the bearing body and the bearing mount.
  • One of the components has a latching element in the form of a latching projection [or a latching recess], while the other component has a counter-latching element with which a latching recess [or a latching projection] is formed.
  • the latching projection is positively accommodated in the latching recess, with the result that locking takes place in the form of a latching.
  • the user applies a force which (in particular as a result of an existing inclined surface) leads to an elastic deformation or elastically supported movement of the snap-in projection and/or the snap-in recess, which means that for the assembly the entry of the snap-in projection into the latching recess and latching in it is made possible and/or the latching projection can exit the latching recess and be released from it for dismantling.
  • a latching device can thus be latched in the direction of assembly or direction of disassembly without further measures by applying sufficient assembly forces or disassembly forces or be unlocked by the form fit is produced or eliminated by means of an elastic deformation.
  • a second embodiment of the locking device is a "locking device".
  • a locking device is formed between two components, here the bearing body and the bearing mount.
  • One of the components has a locking element in the form of a locking projection [or a locking recess], while the other component has a counter-locking element with which a locking recess [or a locking projection] is formed.
  • the locking projection is positively accommodated in the locking recess, with the result that locking takes place in the form of locking.
  • Disassembly and/or assembly of the locking connection (in contrast to the latching device) cannot be carried out solely by the user applying a sufficiently large force in the direction of assembly or direction of disassembly.
  • the locking device is locked or unlocked by a separate manual actuation of the locking element or the counter-locking element, by means of which the locking element or the counter-locking element (at least with a movement component) is moved transversely to the assembly direction or disassembly direction of the components.
  • a transverse surface oriented transversely to the direction of assembly and/or disassembly is preferably effective in the locking device between the locking element and the counter-locking element.
  • the bearing body it is possible within the scope of the invention for the bearing body to be inserted into the bearing receptacle by means of a latching action and for the bearing body to exit from the bearing receptacle to be unlatched, for which purpose the necessary forces must be applied in each case. It is also possible for locking to take place when the bearing body is inserted into the bearing mount and for the exit from the bearing mount to require unlocking, which means that the locking element or the counter-locking element has to be actuated separately.
  • the bearing mount can be a recess.
  • the bearing cross section of the bearing body can then be arranged in this recess.
  • the recess is then delimited jointly by the pliers jaw and a counter-locking element.
  • the bearing body (particularly in the direction of the crimping force) can be supported directly on the pliers jaw.
  • the counter-locking element can be designed as a latching element and/or locking element. According to this proposal, the counter-locking element can be moved between a locking position and a release position (and vice versa). In the locking position, the counter-locking element prevents the bearing body from exiting the recess.
  • the bearing body in the release position of the counter-locking element, the bearing body can emerge from the recess. If the counter-locking element is a latching element, the movement from the locking position to the release position is brought about by elastic movement of the counter-locking element as a result of sufficient removal forces on the bearing body and/or a movement of the counter-locking element from the release position to the locking position takes place through the elastic loading of the counter-locking element. On the other hand, for the formation of the counter-locking element as a locking element, a movement from the locking position to the release position (or vice versa) must take place by separate manual actuation of the locking element.
  • the locking element or the counter-locking element prefferably has an insertion bevel.
  • the insertion bevel is opposite to an insertion direction for the Inserting the bearing body into the bearing seat at an angle (preferably at an angle that is greater than 0° and less than 90°, for example at an angle between 15° and 75°).
  • This inclination of the insertion bevel means that when the bearing body is inserted in the direction of insertion into the bearing receptacle, the bearing body comes to rest against the insertion bevel.
  • the assembly or insertion force is then converted into an actuating force acting on the (counter) locking element, which acts on the (counter) locking element elastically from the locking position in the direction of the release position.
  • the (counter) locking element is designed as a latching element.
  • the (counter) locking element it is also possible for the (counter) locking element to have a locking surface.
  • the locking surface is oriented transversely to the insertion direction for inserting the bearing body into the bearing receptacle or transversely to the removal direction for removing the bearing body from the bearing receptacle. If the bearing body is introduced into the bearing receptacle in the insertion direction with an assembly or insertion force, the bearing body comes to rest on the locking surface, which means that the bearing body cannot enter. Rather, entry can only take place when a separate manual actuation of the counter-locking element takes place. Accordingly, the bearing body cannot be removed from the bearing mount simply by applying a removal force.
  • the counter-locking element can be guided so as to be displaceable relative to the jaw of the pliers (for example in a direction transverse to the crimping axis or inclined relative to it).
  • the counter-locking element can be supported by a spring in relation to the jaw of the pliers, wherein the spring can act on the counter-locking element in the direction of the locking position. If the counter-locking element is guided transversely to the crimping axis opposite the jaw of the pliers and does not have an insertion bevel or removal bevel, the counter-locking element forms a locking element that can only be released by separate manual actuation.
  • the counter-locking element can form a latching element if the locking element is not transverse to the crimping axis with respect to the Pincer jaw is performed, but at an acute angle thereto, and / or the locking element and / or the counter-locking element has an insertion bevel or removal bevel.
  • a further embodiment of the invention is based on the finding that under certain circumstances the die half must be supported during the crimping process on the pliers jaw by means of the crimping force at a force level which is an order of magnitude greater than the force level for securing the die half unit against unwanted removal .
  • the invention proposes that the crimping force be supported by the bearing body (exclusively or largely) in the bearing receptacle on the jaw of the pliers, while a removal force is supported (exclusively or largely) by the counter-locking element.
  • the jaw of the pliers can be correspondingly solid and made of metal, for example, in order to enable the high crimping force to be reliably supported.
  • lower requirements apply with regard to supporting the removal force via the counter-locking element, so that the counter-locking element can be made of plastic, for example, and any guidance of the counter-locking element must also meet lower requirements.
