Description

Technical Field

[0001] This invention relates to a crimping pliers in which the jaws move relative to each other by manually operating a handle via a drive mechanism, such as a crankshaft drive. With the movement of the jaws, the half-die units held on the jaws can be brought closer together by a crimping stroke, thereby crimping a workpiece between the half-die units. The workpiece is, for example, a plug having a cable end region disposed therein, the cable having at least one electrical conductor. The crimping ensures not only a mechanical connection between the plug and the cable, but also an electrical connection between the plug and at least one electrical conductor. The crimping pliers according to the invention can be used to create any crimp profile. In particular, trapezoidal or quadrilateral crimps can be created using the crimping pliers.

[0002] The present invention also relates to a half-mold unit, which is determined for use in crimping clamps. Finally, the present invention also relates to a method for assembling a mold formed of two half-mold parts to form crimping clamps. Background Technology

[0003] Document EP0516598 B1 describes an advantageous method where the workpiece can be selectively introduced into the die of a crimping clamp either from the side or the front. For this purpose, EP0516598 B1 proposes that the half-die unit's half-die is rotatably supported on the configured jaws about a crimping axis, such that the half-die can deflect about the crimping axis so that the receiving portion for the workpiece formed by the half-die is oriented either on the side or the front. To provide rotational freedom of the half-die about the crimping axis, each half-die unit has a bearing body, which is here made of plastic as a U-shaped attachment. The sides of the U-shaped bearing body have semi-shell-shaped bearing surfaces on their mutually facing sides, which together form a bearing eye. A rotating pin is supported in this bearing eye, the rotating pin being formed by the half-die on the side facing away from the die profile. On the outer side, the U-shaped sides of the bearing body have coaxially facing cylindrical short shafts. To assemble the half-die unit on the configured jaws, the sides of the U-shaped bearing body are first pressed together. In this state, the bearing body is inserted into the plate space of the jaw. With the elastic rebound of the bearing body's side, the short shaft enters the corresponding bearing eye of the jaw plate, thereby supporting the bearing body rotatably relative to the jaw about a swing axis, wherein the swing axis is oriented perpendicularly to the jaw head plane. The assembly of the half-die onto the bearing body is achieved by inserting a rotating pin into the bearing eye of the bearing body. Protection of the half-die on the bearing body is achieved by screwing a screw with a washer into the free end side of the rotating pin, thereby supporting the bearing body between the washer and the base of the half-die in the area surrounding the bearing eye. A swivel bearing—by means of which the half-die is rotatably supported relative to the bearing body about the pressing axis—is provided by a receiving portion of the rotating pin in the bearing eye. To ensure that the two half-die deflections about the corresponding swivel bearings and about the pressing axis are achieved at the same swing angle, and thus also ensure the required identical orientation of the die profiles of the half-die, parallel guide pins, according to EP0516598 B1, extend from one half-die toward the other. These guide pins reach the receiving portion of the guide in the corresponding guide hole in the base of the other half-die.

[0004] Reference DE 197 28 685 A1 further proposes equipping the rotary bearing with a locking mechanism, by which the rotary bearing half is rotatably supported relative to the bearing body, thereby enabling locking of the half for orientation both forward and sideways. The locking mechanism here has a spring clip held by the bearing body, which engages with a long slot in the rotary pin for locking with the locking protrusion.

[0005] Documents WO 2019 / 105703 A1 and WO 2019 / 105704 A1 jointly disclose a half-die unit that can deflect relative to the jaws about the crimping axis. Here, the half-die units are not guided relative to each other in guide holes via receptacles for guide pins. Instead, each half-die has half-die bodies oriented parallel to each other, which are staggered together, thereby ensuring guidance transverse to the die plate. Additional guidance is achieved by a guide plate, the surface normal of which extends parallel to the die plate. Both half-die units are designed identically in this configuration. To ensure the rotatability of the half-die about the crimping axis, the base of the half-die has a hole in which the bearing pin of the bearing body is rotatably supported. Axial protection of the bearing pin in the hole of the half-die is achieved by a U-shaped insert that can be guided through a groove on the side of the half-die. In the assembled position, the insert is fixedly positioned in the groove of the half-die along the direction of the crimping axis. The side of the U-shaped insert engages with the corresponding groove of the rotating pin, thereby axially fixing the rotating pin in the half-die. The bottom of the groove of the rotating pin can be constructed to be non-circular, thereby enabling the locking of the rotational position of the half-die around the rotating bearing and around the pressing shaft. To remove the half-die from the bearing body, the insert needs to be pulled out under the elastic expansion of the insert. For this purpose, the insert must be gripped in the area of ​​the bottom edge of the U-shape using pliers, or a pushing force must be applied to the end side of the U-shaped insert using a sharp tool. The bearing body has a sway pin oriented transversely to the pressing shaft outside the half-die, which includes guide claws formed on the end side. The sway pin is received here in a bearing housing of the jaws, which extends beyond the semicircular extension of the sway pin to provide anti-loss fixation of the rotating pin. The reception of the sway pin in the bearing housing ensures the degree of freedom of the half-die unit to swing about the sway axis relative to the configured jaws, the sway axis being oriented perpendicularly to the jaw plane.

[0006] Other prior art is known from document EP 0 888 850 A2. Summary of the Invention

[0007] The object of this invention is to provide a crimping clamp, which is particularly improved in the following aspects:

[0008] - Assembly of semi-mold units or molds; and / or

[0009] - Disassembly of the semi-mold unit or mold; and / or

[0010] - Support of the half-die unit on the jaws of the crimping pliers; and / or

[0011] - Reliability of the connection between the half-die unit and the jaws of the crimping pliers.

[0012] Furthermore, the object of the present invention is to provide:

[0013] - Correspondingly improved half-module units; and

[0014] - A method for assembling a mold with two half-mold units to form a crimping clamp.

[0015] According to the present invention, the objective of the invention is achieved through the features of the invention. Further preferred embodiments according to the invention can be found in the specification and drawings.

[0016] The crimping pliers of the present invention have a die for crimping a workpiece. The die has two die halves, each supported on a jaw of the crimping pliers. Each die halves has a die half and a bearing body. Here, the die halves form a die half profile, which interacts with the workpiece during the crimping process.

[0017] Each bearing housing is supported within a bearing receptacle of the configured jaws, thus forming a half-die bearing. The half-die bearing should allow for the detachable assembly of the half-die unit onto the jaws, thereby ensuring the half-die remains permanently on the configured jaws. Furthermore, the half-die bearing transmits the pressing force generated by the operating handle and potentially amplified by the drive mechanism from the jaws to the half-die unit, which can press the half-die against the side of the workpiece. Additionally, the half-die bearing provides an unrestricted or restricted degree of freedom of oscillation along a pivot axis oriented perpendicularly to the jaw plane. This degree of freedom allows for relative deflection of the half-die unit relative to the jaws for adjustment movements necessary during the jaw's pressing stroke, as the relative angle between the jaws changes due to their deflection.

[0018] Furthermore, each die half is rotatably supported relative to a configured bearing body about a pressing axis via a rotary bearing. This rotational freedom allows the orientation of the die half to be changed as needed, such that the workpiece can be introduced into the die from the side or front (or in any other direction) and / or can be pressed during the pressing process in such an orientation. For this purpose, a pressing clamp can also be designed, for example, according to the embodiment mentioned at the beginning of this document.

[0019] According to the invention, the bearing housing of the half-die unit can be assembled and disassembled with the bearing housing of the jaws without tools and therefore entirely manually. This eliminates the need for connections made by means of threads, riveting, or bolts secured by clasps or spring rings, which must be pried open by the pliers. In this way, it becomes possible to operate the mechanical clamps of the crimping pliers containing the half-die unit with different die profiles, crimping strokes, and so on, because die replacement can be achieved simply and without tools. Such replacement can also be achieved if the half-die unit is worn or if a different type of workpiece needs to be crimped, but this requires the use of a different half-die unit.

[0020] The design according to the present invention—which enables tool-free assembly and disassembly—offers significant advantages over crimping pliers known in the prior art because:

[0021] -According to document EP 0 516 598 B1, in addition to the elastic compression of the bearing housing, replacement also requires the threaded connection between the washer and the rotating pin, which necessitates a screwdriver-type tool; and

[0022] - According to document DE 197 28 685 A1, the locking ring needs to be loosened, which also requires tools.

[0023] According to the present invention, the first half-mold unit of the first variant is connected to the first bearing receiving portion of the first jaw, while the second half-mold unit of the second variant is assembled with the configured second jaw.

[0024] In the first variant, the assembly of the first bearing body and the first bearing housing is achieved by placing the first bearing body in an introduction orientation and inserting it into the first bearing housing in the direction of that orientation. In the introduction orientation of the first bearing body, it is possible for the first bearing body to exit the first bearing housing in the opposite direction of movement. However, according to the invention, immediately following this, in order to continue the assembly, the first bearing body is deflected so that it occupies a protective orientation in the first bearing housing. In this protective orientation, the first bearing body and the first bearing housing form a form fit or a "hook" in the direction of the protective orientation. Therefore, in the direction of the protective orientation, the first bearing body cannot exit the first bearing housing, thereby achieving a reliable assembly. Preferably, the first bearing housing occupies the introduction orientation only in the (partial) assembled state of the crimping clamp, while the first bearing body occupies the protective orientation or an adjacent swinging position in the first bearing housing only during normal operation of the crimping clamp and during the crimping process, where the form fit or hook is still ensured. In short, this assembly is achieved by means of the deflection of the first bearing body relative to the first bearing housing. This deflection enables the first bearing body and the first bearing housing to fit together or become hooked together.

[0025] For the sake of merely providing examples without limiting the invention, the first bearing body may be constructed as a hook, or may have a U-shaped receiving portion open in the insertion orientation. Thus, the hook or U-shaped receiving portion may be positioned in front of a transverse bolt forming the first bearing receiving portion. Consequently, as the first bearing body deflects to a protective orientation, a form fit can be achieved between the hook and the transverse bolt or U-shaped receiving portion in the direction of the protective orientation, which corresponds to the crimping shaft during operation.

[0026] Within the framework of this invention, it is possible that, for the first variant, the first bearing body is deflected from the guide orientation to the protection orientation, causing a shape fit with the side recess of the first bearing housing along the direction of the protection orientation, which ensures that the support or bearing of the first bearing body on the first bearing housing is free from disassembly.

[0027] Within the framework of this invention, for the first variation, the described shape fit is only, or may also be effective, in protecting the first bearing body from being removed from the first bearing housing along the protective orientation.

[0028] Within the framework of this invention, for the first variant, it is preferable that no additional protective element is required, thereby providing a connection only with the first bearing body and the first bearing housing, which simplifies assembly and / or disassembly and also reduces the number of structural components required (although additional protective elements may also be used).

[0029] Within the framework of this invention, for the first variant, the deflection to the guide orientation and / or to the protection orientation may also be elastically deformable or may not require elastic deformation of the structural components involved.

[0030] Within the framework of this invention and for the embodiments described in the accompanying drawings, in the first variation, the first bearing housing is constructed with a groove for the first jaws, into which the first bearing body enters. However, it is also entirely possible, in other corresponding designs, for example, that the first bearing body forms a groove into which a protrusion of the first bearing housing can enter.

[0031] In a proposed first variant of the invention, the first bearing housing has a bearing eye. Here, the cross-section of the bearing eye is not edge-closed. Instead, the bearing eye has an edge opening. This edge opening forms a narrow portion relative to the bearing size of the bearing eye. A first bearing body forms a bearing cross-section, which is rotatably supported in the bearing eye. This bearing cross-section has an insertion extension transverse to the insertion orientation. It also has a protection extension transverse to the protection orientation. The protection extension is larger than the narrow portion of the bearing eye. If the bearing cross-section of the first bearing body is located in the bearing eye of the first bearing housing in the protection orientation, the bearing cross-section, and consequently the first bearing body, cannot exit the bearing eye because the bearing cross-section with the protection extension cannot pass through the narrow portion. The protection extension can here form a shape-fitting conformal with the lateral recess formed by the narrow portion of the bearing eye. In contrast, the insertion extension is smaller than the narrow portion of the bearing eye, thus, if the first bearing body is in the insertion orientation, the first bearing body can be inserted into the bearing eye, allowing the bearing cross-section to pass through the narrow portion of the bearing eye.

[0032] Various possibilities exist for the geometry of the first bearing body and, particularly, the bearing cross-section disposed within the bearing eye, for the first variation of the invention. In the proposed embodiment, the first bearing body has a cylindrical section and a leveling portion to form the bearing cross-section, wherein the leveling portion can be arbitrarily bent, as long as it lies within the side of the cylindrical section continuing through the cylindrical section. In the region of the cylindrical section, the bearing cross-section thus has a protective extension, while in the region of the leveling portion, the bearing cross-section has an introductory extension.

[0033] According to the invention, in the second variation, the second bearing body and the second bearing housing are interconnected by a stop mechanism. The stop mechanism does not achieve "complete" fixation of the second bearing body relative to the bearing housing. Instead, it merely restricts or eliminates at least one degree of freedom (particularly assembly and / or disassembly freedom) between the second bearing body and the second bearing housing. Preferably, this stop mechanism ensures the swing freedom of the second bearing body relative to the second bearing housing about a rotation axis oriented perpendicular to the pliers head plane.

[0034] In the first design of the stopping mechanism, the stopping mechanism is a "locking mechanism". Such a locking mechanism is configured between two structural members, specifically between the second bearing housing and the second bearing receiving portion. One of the structural members has a locking element in the form of a locking protrusion [or locking groove], while the other structural member has a corresponding locking element, which forms a locking groove [or locking protrusion]. In the locked position of the structural member, the locking protrusion is shape-fitted into the locking groove, thereby achieving a locking-type stop. For disassembly and / or assembly of the locking connection, the user applies a force (particularly due to the presence of an inclined plane) that causes elastic deformation or elastic support movement of the locking protrusion and / or locking groove, thereby enabling the locking protrusion to enter and lock into the locking groove for assembly, and / or enabling the locking protrusion to exit and unlock from the locking groove for disassembly. Therefore, without additional measures, the locking mechanism can be locked or unlocked in the assembly or disassembly direction by applying sufficient assembly or disassembly force, which is achieved by forming or eliminating shape fit through elastic deformation.

[0035] In the second design of the stopping mechanism, the stopping mechanism is a "locking mechanism." Such a locking mechanism is configured between two structural members, specifically between the second bearing body and the second bearing housing. One of the structural members has a locking member in the form of a locking protrusion [or locking groove], while the other structural member has a corresponding locking member, which forms a locking groove [or locking protrusion]. In the locked position of the structural member, the locking protrusion is shape-fitted into the locking groove, thereby achieving a locking-type stop. The disassembly and / or assembly of the locked connection can be (unlike a locking mechanism) not achieved solely by the user applying a sufficiently large force along the assembly or disassembly direction. Instead, the locking or unlocking of the locking mechanism is achieved by a separate manual operation of the locking member or corresponding locking member, by means of which the locking member or corresponding locking member (with at least one motion component) moves laterally to the assembly or disassembly direction of the structural member. Preferably, in the case of the locking mechanism, a lateral surface oriented laterally to the assembly and / or disassembly direction between the locking member and the corresponding locking member is effective.

[0036] Within the framework of this invention, it is theoretically possible that the second bearing body is inserted into the second bearing housing by means of locking, and the second bearing body needs to be unlocked to exit the second bearing housing, for which each requires the application of the necessary force. It is also possible that the second bearing body is locked as it is inserted into the second bearing housing, and the second bearing body needs to be unlocked to exit the second bearing housing, thus requiring separate manual operation of the locking element or corresponding locking element. For a particular proposed embodiment of the invention, locking is achieved by a locking mechanism when the second bearing body is inserted into the second bearing housing, so that without the need to operate a separate manual (corresponding) locking element, the second bearing body must simply approach the second bearing housing and be pressed into the second bearing housing with sufficient assembly force until the second bearing body is locked in the second bearing housing. In contrast, with this proposed embodiment, the second bearing body is locked from exiting the second bearing housing, thus requiring the operation of a separate manual (corresponding) locking element for the second bearing body to exit the bearing housing. This ensures simple assembly of the second bearing body in the second bearing housing on the one hand, but on the other hand, reliably ensures that undesirable exit from the second bearing housing does not occur. Instead, the second bearing body can only exit the second bearing housing if the user can manually do so by operating a separate (corresponding) locking element. Furthermore, the proposed solution cannot result in the second bearing body undesirably detaching from the second bearing housing due to misoperation of the crimping pliers or malfunction of the crimping pliers—leading to a pulling force acting on the half-die unit.

[0037] In one embodiment of the invention, the second bearing housing may have a groove. The bearing cross-section of the second bearing body can then be provided in this groove. The groove is thus jointly limited by the second jaws and a corresponding stop. On one hand, this allows the second bearing body to be directly supported on the second jaws (particularly in the direction of the pressing force). The corresponding stop can be configured as a locking and / or latching element. According to this proposed embodiment, the corresponding stop is movable between a stopped position and a released position (and vice versa). In the stopped position, the corresponding stop prevents the second bearing body from exiting the groove. In contrast, in the released position of the corresponding stop, the second bearing body can exit the groove. If the corresponding stop is a locking element, the movement from the stopped position to the released position is caused by the elastic movement of the corresponding stop due to sufficient pull-out force on the second bearing body, and / or by the elastic action of the corresponding stop on the corresponding stop. In contrast, for a corresponding stop constructed as a locking element, the movement from the stop position to the release position (or vice versa) must be achieved through a separate manual operation of the locking element.

[0038] For example, the stop or corresponding stop may have an inlet ramp. The inlet ramp is inclined relative to the inlet direction for the second bearing body to enter the second bearing housing (e.g., at an angle greater than 0° and less than 90°, such as an angle between 15° and 75°). This inclination of the inlet ramp causes the second bearing body to abut against the inlet ramp when it is inserted into the second bearing housing in an inlet orientation. On the inlet ramp, the assembly or inlet force is then converted into an operating force acting on the (corresponding) stop, which elastically moves the (corresponding) stop from the stop position toward the release position. In this case, the (corresponding) stop is thus configured as a locking element.

[0039] However, it is also possible that the (corresponding) stop has a locking surface. In this case, the locking surface is oriented transversely to the insertion direction for inserting the second bearing body into the second bearing housing or transversely to the removal direction for removing the second bearing body from the second bearing housing. If the second bearing body is inserted into the second bearing housing with the insertion orientation and an assembly or insertion force, the second bearing body abuts against the locking surface, thus making it impossible for the second bearing body to enter. More precisely, entry can only be achieved by performing a separate manual operation of the corresponding stop. Accordingly, the second bearing body cannot be removed from the second bearing housing simply by applying a removal force. More precisely, the removal force only causes the second bearing body to press against the locking surface, but does not cause the locking surface to move to eliminate the form fit. Moreover, a separate manual operation of the corresponding stop is required to unlock it in order to remove the bearing body.

[0040] In another embodiment of the invention, the corresponding stop can be movably guided relative to the second jaw (e.g., in a direction transverse to or inclined relative to the crimping shaft).

[0041] Furthermore, the corresponding stop can be supported by a spring relative to the second jaw, wherein the spring can act on the corresponding stop in the direction of the stop position. If the corresponding stop is guided transversely to the crimping shaft relative to the second jaw and does not have an entry ramp or a exit ramp, then the corresponding stop forms a locking element, which can be released by a single manual operation. In contrast, if the stop is not guided transversely to the crimping shaft relative to the second jaw but at an acute angle thereto and / or the stop and / or the corresponding stop has an entry ramp or an exit ramp, then the corresponding stop can form a locking element.

[0042] Another design of the invention is based on the understanding that the support of the second half-die on the second jaws during the crimping process may need to be achieved by means of a crimping force at a force level that is an order of magnitude larger than the force level used to protect the second half-die unit from undesirable removal. Based on this understanding, the invention proposes that the support of the crimping force is achieved (only or as much as possible) by a second bearing body in a second bearing housing on the second jaws, while the support of the removal force is achieved (only or as much as possible) by a corresponding stop. The second jaws can here be correspondingly solid and, for example, made of metal, to achieve reliable support of the high crimping force. In contrast, lower requirements are applied to the support of the removal force via the corresponding stop, such that, for example, the corresponding stop can be made of plastic and the possible guidance of the corresponding stop must meet lower requirements.

[0043] Within the framework of this invention, it is possible that assembly and / or disassembly are carried out in a direction located in the plane of the jaw head, wherein assembly can also be carried out from the inside of the jaws, for example in an assembly direction approximately corresponding to the crimping force acting in operation.

[0044] In principle, the two half-die units of the crimping pliers can be configured differently and can be matched to different required half-die profiles and / or have different connections with the configured jaws. In one proposed embodiment of the invention, the first and second half-die units are structurally identical, thereby preferably achieving symmetrical crimping of the workpiece. This reduces component diversity.

[0045] Within the framework of this invention, the half-die unit can have a bearing body with different coupling sections, wherein a first coupling section can achieve a connection on the first jaw according to a first variation, and a second coupling section can achieve a connection on the second jaw according to another variation. Preferably, the two coupling sections are arranged side-by-side in a view along the swing axis of the half-die bearing, which ensures that the swing axis of the half-die bearing about the half-die unit is the same when the first coupling section is connected to the first bearing housing of the first jaw, as is the swing axis of the half-die bearing when the second coupling section is connected to the second bearing housing of the second jaw.

[0046] Another solution to the objective of this invention is a half-die unit, particularly for use in crimping pliers as described above. Such a half-die unit has a half-die and a bearing body. The bearing body is configured to form a half-die bearing via support in a bearing housing provided to the plier jaws. The half-die unit further has a rotary bearing by which the half-die is rotatably supported relative to the bearing body about the crimping shaft. The bearing body is hereby configured cumulatively according to two variations as follows:

[0047] In the first variant, the bearing body has a bearing cross-section that has a protective extension transverse to the protective orientation and a guide extension transverse to the guide orientation. Here, the protective extension is greater than the guide extension. Preferably, the bearing body here has a cylindrical section whose diameter corresponds to the protective extension. Furthermore, the bearing body then also has a leveling section, in which the bearing body has the guide extension.

[0048] In the second variation, the bearing housing has a stop. This stop allows the bearing housing to form a stopping mechanism with the bearing housing of the jaws. In this case, the bearing housing has a corresponding stop. The stop and the corresponding stop thus constitute a locking or latching mechanism.

[0049] For the semi-mold unit according to the invention, these modifications are cumulatively implemented on the bearing body, whereby the bearing body has two coupling sections, for example, arranged side by side, for coupling with the bearing receiving portion of the jaws. One coupling section thus provides a bearing cross-section for protecting the extension and guiding the extension, while the other coupling section has a stop. The semi-mold unit thus formed can then be connected to the configured jaws not only in a first connected modification but also in a second connected modification.

[0050] Another solution to the objective of this invention proposes a method for assembling a mold having two half-molds as described above to form a crimping clamp. In this method, firstly, a first bearing body of the first half-mold unit is inserted into a first bearing housing disposed in the first clamping jaws in an insert orientation. Immediately thereafter, the first bearing body is deflected to a protective orientation, thus making it impossible for the bearing body to exit along the protective orientation. Next, a second bearing body is inserted into a second bearing housing, and simultaneously, the second bearing body is stopped in the second bearing housing by means of a locking or clamping mechanism. Preferably, the two half-mold units are connected to each other and guided relative to each other in the crimping direction before the method steps are performed, or the connection of the two half-mold units is achieved before the second bearing body is inserted into the second bearing housing. If the second bearing body is stopped in the second bearing housing, the first bearing body cannot be reversed to the insert orientation without eliminating the stop of the second bearing body in the second bearing housing. Therefore, it is only possible to disassemble the two half-mold units (single or together) when the second bearing body is stopped in the second bearing housing, which preferably requires release or unlocking by separate manual operation of the corresponding locking element.

[0051] Preferably, no additional method steps are required for assembling the half-die unit on the configured jaws, in particular no threaded connection, no protective ring assembly, no pressing, and the like.

[0052] Further improvements to the invention are made in other parts of the specification and the accompanying drawings.

[0053] The advantages of the features and combinations of features described in the specification are merely exemplary and may work alternatively or cumulatively, without requiring that each advantage be achieved by the various embodiments according to the invention.

[0075] In the accompanying drawings and descriptions, the same reference numerals are applied in part to structural elements or portions thereof that correspond at least partially to their shape and / or function. These structural elements are distinguished here in part by supplementary letters a, b, ... etc. Thus, reference numerals with or without the supplementary letters a, b, ... may refer to these structural elements, thereby referring to a single structural element, multiple structural elements thus indicated, or all structural elements indicated by reference numerals.

[0076] Figure 1 The crimping clamp 1 is shown in the open position, while the crimping clamp 1 is in... Figure 2 It is shown in a closed state.

[0077] The crimping pliers have a fixed handle 2, which is connected to a fixed first jaw 3. Furthermore, the crimping pliers 1 have a movable handle 4. The movable handle 4 can be operated by applying hand force by the user's hand according to… Figure 1 The open position deflection to according to Figure 2 The closed position is reached, wherein handles 2 and 4 approach each other as the closing motion occurs. Handle 4 is coupled to the moving second jaw 6 via drive mechanism 5. The closing stroke of handles 2 and 4 also achieves the closing motion of the moving jaw 6, during which jaws 3 and 6 move from the open position to the closed position. This motion represents the working stroke during the crimping process, through which the workpiece is crimped.

[0078] The drive mechanism 5 ensures that the movement and force of the handles 2 and 4 are properly transmitted to the jaws 3 and 6. The drive mechanism 5 can be configured in any manner known from existing technology. Preferably, the drive mechanism 5 is a crank-lever mechanism 7.

[0079] In one possible design of the crank-lever mechanism 7, the movable jaw 6 is supported, oscillatingly or deflectably, on the fixed jaw 3 or a fixed jaw body via a sway bearing. The jaw body not only forms the fixed jaw 3 but also includes a fixed handle 2. The movable handle 4 is hinged to the movable jaw 6 via a sway bearing 8. Furthermore, one end region of a pressure lever 10 is hinged to the movable handle 4 at an elbow joint 9. The other end region of the pressure lever 10 is hinged to the fixed handle 2 via a sway bearing or to the fixed jaw body that constitutes the fixed jaw 3 and the fixed handle 2. Between the sway bearing 8 and the elbow joint 9, the fixed handle 2 forms a first crank lever 11, while the pressure lever 10 forms a second crank lever 12.

[0080] Figure 1 and 2 The drawing plane corresponds to the jaw plane 13, in which the handles 2 and 4 deflect relative to each other, drive the movement of the structural components of the driving mechanism 5, and / or realize the movement of the jaws 3 and 6. A crimping force also applies in the jaw plane 13, and a crimping shaft 19 extends from there.

[0081] A mold 14 is held on jaws 3 and 6. Mold 14 has a first half-mold unit 15a and a second half-mold unit 15b. Each half-mold unit 15 has a first and second bearing body 16 and a first and second half-mold 17. The half-mold 17 forms a half-mold profile that limits a mold receiving portion 18. A workpiece can be inserted into the mold receiving portion 18. In the mold receiving portion 18, the workpiece is pressed between the mold profiles of the half-mold 17 during the pressing process. This is achieved by the relative movement of the half-mold 17 along the pressing axis 19.

[0082] The orientation of the crimping shaft 19 changes relative to the jaws 3 and 6 during the crimping process. For this purpose, the bearing housing 16 of the half-die unit 15 and the first and second bearing receptacles 20 of the jaws 3 and 6 form first and second half-die bearings 21. The half-die bearings 21 provide a degree of freedom of oscillation about a swing axis 22 between the bearing housing 16 and the disposed jaws 3 and 6, the swing axis 22 being oriented perpendicularly to the jaw head plane 13.

[0083] Each of the mold halves 17 has a guide protrusion 23 on one side next to the mold receiving portion 18 and a guide groove 24 on the other side next to the mold receiving portion 18. The guide protrusion 23a of half mold 17a is guided and received in the guide groove 24b of the other half mold 17b. Correspondingly, the guide protrusion 23b of half mold 17b is guided and received in the guide groove 24a of half mold 17a. In this way, the half molds 17 are guided parallel to the pressing shaft 19 on both sides of the mold receiving portion 18, thereby ensuring that the half molds 17a and 17b are oriented relative to each other in a conventional manner during the pressing process.

[0084] The connection between the bearing body 16 and the configured half mold 17 is achieved by means of a rotary bearing 25, so that the half mold 17 is rotatable about the pressing shaft 19 relative to the bearing body 16.

[0085] The bearing body 16, due to the half-die bearing 21, has only a oscillating degree of freedom about the oscillating axis 22 relative to the configured jaws 3, 6. The half-die 17, due to the rotating bearing 25, has only a rotational degree of freedom about the pressing axis 19 relative to the bearing body 16. Finally, the two half-die 17s, guided by the guide protrusion 23 and the guide groove 24, have only a translational degree of freedom in the direction of the pressing axis 19. Due to the coupling of the two half-die 17s through this guidance, the two half-die 17s can rotate together about the pressing axis 19.

[0086] Figure 3 The front view of the crimping clamp 1 in the mold 14 region is shown, revealing the comb-like staggered connection of the two mold halves 17. Furthermore, the design of the guide groove 24 with guide holes and the guide protrusion 23 serving as guide rods is also visible.

[0087] Figure 4A locking mechanism 26 is shown, which can lock the rotational position of the mold half 17 relative to the bearing body 16 about the pressing shaft 19. The locking mechanism 26 includes a locking spring 27 and a locking ball 28. The locking spring 27 and the locking ball 28 are housed in grooves or holes in the bearing body 16 oriented parallel to the pressing shaft 19. The locking spring 27 acts on the locking ball 28 toward the end face 29 of the mold half 17. A locking groove 30 is present in the end face 29, in which the locking ball 28 can be locked by the action of the locking spring 27. A plurality of such locking grooves 30 are distributed around the circumference of the pressing shaft 19, thus enabling locking of the mold half 17 at different rotational angles relative to the bearing body 16. Preferably, at least one locking mechanism is implemented when the mold receiving portion 18 is laterally oriented, that is, when the longitudinal axis of the mold receiving portion 18 is perpendicular to the jaw plane 13, and when the front portion of the mold receiving portion 18 is oriented, that is, when the longitudinal axis of the mold receiving portion 18 is oriented in the jaw plane 13.

[0088] Figure 5 A spatial view of half-mold 17b is shown. Here it can be seen that half-mold 17b has multiple pairs of sheet-like and parallel ribs 31a, 31b, ... and 32a, 32b, ... and receiving spaces 33a, 33b, ... and 34a, 34b, ... formed between the ribs 31, 32. If according to... Figure 5 The comb-shaped half-mold 17b is pushed into the corresponding, but oppositely arranged half-mold 17a, so that the rib 31 of half-mold 17a enters the receiving space 34 of half-mold 17b, while the rib 32 of half-mold 17a enters the receiving space 33 of half-mold 17b. Conversely, the ribs 31 and 32 of half-mold 17b can enter the receiving spaces 33 and 34 of half-mold 17a. The mold profile provided by the end sides of the ribs 31 and 32 limits the mold receiving portion 18. During the pressing process, the ribs 31 and 32 continue to enter the receiving spaces 33 and 34, thereby reducing the size of the mold receiving portion 18 and achieving pressing of the workpiece within the mold receiving portion 18. The staggered connection of the parallel ribs 31 and 32 of the two half-molds 17 is achieved such that the ribs 31 and 32 can approach each other with a small gap or no gap along the sliding side. The comb-like staggered connection of ribs 31 and 32 provides guidance along the direction of the crimping axis 19, wherein the guidance prevents relative movement of the half molds 17 relative to each other along the plane normal direction of ribs 31 and 32. Additional guidance between the half molds 17 is achieved by guidance protrusions 23 in guide grooves 24.

[0089] For in Figure 5 In the embodiment shown, the guide protrusion 23 is formed by a thickened portion 35 of the intermediate rib 33d. In the illustrated embodiment, the thickened portion 35 is cylindrical or partially cylindrical.

[0090] For in Figure 5 In the embodiment shown, the guide groove 24 is composed of a hollow cylindrical portion 36 connected to the end regions of ribs 33c and 33d, and accommodates a rib 31d having a thickened portion 35 between ribs 33c and 33d.

[0091] Figure 6 and 7 The bearing body 16 is shown in different parallel sections, that is, according to Figure 6 In the first sub-section, and according to Figure 7 In the second sub-section. According to... Figure 6 and 7 The sub-section on the same bearing body 16 provides alternative coupling or stopping possibilities for connection with the bearing housing 20 of the jaws 3, 6.

[0092] The bearing body 16 has a pin-shaped protrusion 37 based on a support surface 38. In the end region facing away from the support surface 38, the protrusion 37 has a circumferential groove 39. The pin-shaped protrusion 37 can be inserted into and guided within a receiving hole 78 based on the end face 29 of the mold half 17 to form a rotary bearing 25 rotatable about the crimping shaft 19. With the bearing body 16 thus inserted into the mold half 17, the bearing body 16 on the mold half 17 is protected from undesirable displacement by a protective ring or other protective element 77. The protective ring or protective element 77 is received in the circumferential groove 29 of the bearing body 16 and supported on the support surface provided by the mold half 17. The mold half 17 is thus held between the protective element 77 in the circumferential groove 39 and the support surface 38 (see 8 and 9). The contact of the support surface 38 of the bearing body 16 with the mold half 17 ensures good and large-area transmission of the crimping force between the bearing body 16 and the mold half 17.

[0093] In accordance with Figure 6 In the first cross section, the bearing body 16 has a bearing cross section 40. In the bearing cross section 40, the bearing body 16 has a leveling portion 41 and a columnar portion section 42, or columnar portion sections 42 provided on both sides of the leveling portion 41.

[0094] Laterally to the guide orientation 43, the bearing cross-section 40 has a guide extension 44, which is predetermined by the leveling portion 41. In contrast, the bearing cross-section 40 laterally to the protection orientation 45 has a protection extension 46. The protection extension 46 is larger than the guide extension 44. Here, the protection extension 46 may correspond to the diameter of the column section 42. Compared to... Figure 6With the altered protection orientation 45, if the column section 42 is formed in the end region of the leveling portion 41, the protection extension 46 can also be (slightly) smaller than the diameter of the column section 42. The guide orientation is parallel to the leveling portion 41, while the protection orientation 45 is inclined relative to the guide orientation 43 and, for example, can be oriented along the longitudinal axis of the press shaft 19 or the protrusion 37 in the assembled state. Needless to say, other bearing cross-sections 40 are also possible. For example, the leveling portion 41 can also be constructed as an arch, and / or other outer contours of the bearing cross-section 40 can be applied instead of the column section 42, provided that the foregoing applies to the dimensions of the guide extension 44 and the protection extension 46.

[0095] exist Figure 7 As can be seen in the cross-section shown, the bearing body 16 forms the bearing cross-section 47. Furthermore, this bearing cross-section 47 has at least one cylindrical section 48 and a flattened portion 49. Naturally, the protrusion 50 of the bearing cross-section 47 forms a stop 51, which can be configured as a locking element 52 and / or a locking element 53. It is possible that the bearing cross-section 47 is configured as a "hook shape" as shown. The protrusion 50 extends transversely to the longitudinal axis of the protrusion 37 and parallel to the support surface 38 on the side of the bearing cross-section 47 opposite to the protrusion 37, with a transverse surface 54.

[0096] The stop 51 has a transverse surface 54 on the side facing away from the protrusion 37, the transverse surface 54 being oriented transversely to the longitudinal axis of the protrusion 37. Furthermore, the stop 51 has a transverse surface 55 on the side facing the protrusion 37. The transverse surface 55 transitions to a ramp 56 in the usable end region, which in turn transitions to the transverse surface 54 via a rounded protrusion 57. The protrusion 57 forms a side recess 58 in the region of the transverse surface 55. In the region of the side recess 58, a locking or latching groove 59 is configured for locking or latching.

[0097] Figures 10 to 13 The assembly of the bearing body 16a of the semi-mold unit 15a in the area of ​​the bearing cross-section 40 and the bearing receiving portion 20 of the fixed jaw 3 is shown. The bearing receiving portion 20 of the fixed jaw 3 here has a cross-section including a bearing surface with a cylindrical portion shape. The circumferential angle of the cylindrical portion of the bearing surface is here greater than 180° or less than 180°, for example, 110° to 180° or 130° to 170°. The cross-section of the bearing receiving portion 20 has an edge opening 60 at the location away from the cylindrical bearing surface. The edge opening 60 here forms a narrow portion 61 of the bearing receiving portion 20, thereby forming a side recess 62 in the interior of the bearing receiving portion 20 after the narrow portion 61. The bearing receiving portion 20 thus constitutes an edge-opening bearing eye 73.

[0098] The edge opening 60 is slightly larger than the guide extension 44 of the bearing cross-section 40 of the bearing body 16. This makes it possible for the bearing body 16 to be guided into the bearing housing 20 along its guide orientation 43 through the edge opening 60 with movement in the guide orientation 43. To prevent the bearing body 16 from exiting the bearing housing 20 again, the bearing body 16 is positioned relative to the bearing housing 20 according to... Figure 11 The import direction 43 is deflected to according to Figure 13 The protective orientation 45. Therefore, the protective extension 46, which functions as a result, prevents the bearing body 16 from exiting the bearing housing 20 opposite to the protective orientation 45 because the narrow portion 61 is larger than the edge opening 60. For the mold 14 fully assembled on the jaws 3 and 6, the bearing body 16 can no longer occupy the guide orientation 43 during operation of the crimping clamp 1 without further disassembly, thus making it impossible for the bearing body 16 to undesirably exit the bearing housing 20. According to... Figure 12 and 13 In the assembled position, the bearing cross-section 40 of the bearing body 16 is supported by the cylindrical section 42 on the bearing surface of the cylindrical portion of the bearing housing 20 by a pressing force. Thus, the acting pressing force is well and extensively supported between the bearing body 16 and the bearing housing 20 of the jaw 3. In contrast, this reliably supports any force acting in the extraction direction, such that the protective extension 46 is supported by the side recess 62 formed by the narrow portion 61 on the material forming the narrow portion 61 of the jaw 3.

[0099] according to Figure 6 The connection method between the bearing cross section 40 and the bearing housing 20 is also referred to as a "first variation" of the connection or support within the scope of this specification. In this first variation, the connection or support is preferably achieved only between the jaws 3 and the bearing body 16, without the need for additional structural members to form the connection or support.

[0100] from Figures 14 to 17 The second variation of the connection or support can be clearly seen, which is added to the first variation for the illustrated embodiment, that is, for the second half-mold unit 15b to be supported on the moving jaw 6.

[0101] The corresponding stop 63 is movably guided relative to the moving jaw 6 along the stop direction 64. Preferably, the stop direction 64 is oriented transversely to the longitudinal axis of the protrusion 37 or the crimping axis 19. The guidance of the corresponding stop 63 is here ensured by two pins 65, 66, which are held on the jaw 6 and guided in the elongated hole 67 of the corresponding stop 63. For structural space reasons, in the illustrated embodiment, the pins 65, 66 have different diameters, so that the elongated hole 67 guided here has sub-sections with different widths corresponding to the different diameters of the pins 65, 66.

[0102] The corresponding stop 63 has an operating surface 68 on the external part of the crimping clamp 1 that is freely accessible to the user. The user can move the corresponding stop 63 between a stopped position and a released position by manually applying an operating force to the operating surface 68. Preferably, the operation can be achieved by the user applying the tip of their thumb to the operating surface 68, which can even be done with the hand positioned on at least one of the handles 2 and 4.

[0103] With the help of the stop spring 69, the corresponding stop 63 is made to move away from the stop according to Figure 14 and 15 The release state is in accordance with Figure 16 and 17 The stop position is directional. The corresponding stop member 63 has a corresponding stop protrusion 70 in the region of the end face, which is acted upon by the stop spring 69 in the direction of the bearing cross section 47 of the bearing body 16.

[0104] The jaws 6, together with the corresponding stop 63 (here, the corresponding stop protrusion 70), constitute the bearing housing 20. If the corresponding stop 63 is located in accordance with... Figure 14 and 15 The bearing cross-section 47 of the bearing body 16 is released into the bearing housing 20, corresponding to the stop member 63. Figure 14 and 15 The position shown has the cylindrical section 48 and the transverse surface 54 abutting against the cylindrical bearing surface of the bearing housing 20, which is provided by the jaws 6. This contact surface thus ensures reliable and large-area support of the crimping force during the operation of the crimping pliers 1. Naturally, the bearing body 16 can also exit from the bearing housing 20 in the release position corresponding to the stop 63. To prevent the bearing body 16 from exiting in this way, the stop spring 69 causes the corresponding stop 63 to move according to... Figure 16 and 17 The stop position is reached. In the stop position, the corresponding stop protrusion 70 engages with the groove 69. The corresponding stop protrusion 70 extends beyond the side recess 62 of the bearing cross section 47. The plane of the transverse surface 71 of the corresponding stop 63 abuts against the transverse surface 55 of the stop 51 of the bearing body 16. If a pull-out force is applied to the bearing body 16, this pull-out force acts in the direction of the pressing force or parallel to the longitudinal axis of the protrusion 37, and thus the pull-out force is supported by the contact of the transverse surfaces 55, 71 without applying a force component acting in the direction of the release position to the corresponding stop 63. This involves locking.

[0105] As an optional feature, only when manually resisted by the action of the stop spring 69, causing the corresponding stop 63 to move according to... Figure 14 , 15In the released position, the bearing cross section 47 cannot be inserted into the bearing housing 20. For this option, the corresponding stop 63 has a ramp 72. If the corresponding stop 63 is in the stopped position and the bearing body 16 is inserted into the bearing housing 20, the bearing body 16 abuts against the ramp 57 with a rounded protrusion 57. The guiding force applied by the user to the bearing body 16 is converted by the ramp 72 into a force component that acts opposite to the action on the corresponding stop 63 by the stop spring 69. Sufficient guiding force can thus cause the corresponding stop 63 to move automatically from the stopped position to the released position, thereby gradually releasing into the bearing housing 20. If the bearing body 16 reaches its final position in the bearing housing 20, the corresponding stop 63 is reversed and locked into the stopped position by the stop spring 69. In this embodiment, the stop mechanism 74 is configured as a locking mechanism 75 so that the bearing cross section 47 is inserted into the bearing receiving portion 20. The stop mechanism 74 forms a locking mechanism 76 to prevent the bearing cross section 47 from being removed from the bearing receiving portion 20. The locking mechanism 76 can only be released when the corresponding stop member 63 is manually moved from the stop position to the release position.

[0106] If the transverse surfaces 55 and 71 are also constructed as inclined surfaces before modification, the connection between the bearing cross-section 47 and the bearing housing 20 can also be unlocked.

[0107] The connection between the bearing body 16 and the bearing housing 20 of the jaws 6 is also referred to as the "second variation" within the scope of this specification. In the second variation, it is preferable to achieve not only a connection or support between the jaws 6 and the bearing body 16, but also at least one additional structural member in the form of a corresponding stop 63 for forming the connection or support. However, it is also possible, in a modified embodiment, that the corresponding stop 63 is integrally formed by the jaws 6 or the bearing body 16, for example, by the stop protrusion being an integral, elastically supported component of the jaws 6 or the bearing body 16.

[0108] It is entirely possible that, unlike the illustrated embodiment, the connection between the mold 14 and the fixed jaw 3 is achieved through a stop mechanism 74, while the connection with the movable jaw 6 is achieved through a bearing cross section 40 having a flattening portion 41.

[0109] It is possible that the bearing cross section 47 is disposed between the two bearing cross sections 40, thereby enabling symmetrical support in the regions of the two bearing cross sections 40 for the connection according to the first variant (see...). Figure 9 ).
