Description

Technical Field

[0001] The invention relates to a tool, for example for fitting or trimming cables, wherein the tool can be used, for example, to crimp connectors to cables and / or to cut or slit cables and / or to remove insulation from cables for stripping cables. The tool can be embodied as a (stationary) machine tool, which can be driven electrically, pneumatically or hydraulically. However, the tool can also be a hand tool. In this case, the tool can be held by hand, while the actuation force is generated electrically, pneumatically or hydraulically. The tool may also be a manually operated hand tool, wherein the actuation force is generated by one or two hands operating a handle. Background Art

[0002] EP2096725B1 describes a crimping pliers for crimping pressed parts, such as wire connections, pipe connections, fittings, cable boots or the like. EP2096725B1 describes a known pressing tool, in which the pressing occurs between half-dies held on the jaws. In this case, multiple pairs of half-dies can be arranged adjacent to each other on the die body, and these half-die pairs have different cross-sections and / or profiles. Then, the user of the pressing tool can selectively insert the workpiece into one of the half-die pairs and press the workpiece there. In this way, different workpieces should be able to be pressed without modifying or replacing the pressing tool. EP2096725B1 also describes that different tool insertion structures with different profiles and cross-sections can be inserted into the tool actuation unit. Then, the tool insertion structure can be fixed to the jaws of the tool actuation unit by a snap-in connection. Finally, it is described in EP2096725B1 that the jaws of the pipe crimping pliers each include a rotating die, which is rotatably mounted on the relevant jaws around the axis of rotation (see DE19628752A1). A plurality of half molds with different profiles and cross sections are distributed along the circumference of the rotary mold. In order to select a specific half mold pair, the user must turn the rotary mold to a specified rotational position in which the selected specific half mold pair is arranged relative to each other. The rotary mold can be stopped at the rotational position required for the corresponding operation of the specific half mold pair by a spring-loaded sliding body engaged with the rotary mold. In the context of this prior art, EP2092725B1 proposes that the tool insertion structure is formed by two insert halves. The insert halves are guided to each other by guide pins so that they can translate relative to each other in the direction of the machining axis. Each insert half includes a plurality of half molds with different profiles and cross sections and arranged adjacently, wherein the relative half molds of the two insert halves form a half mold pair, through which different types of workpieces can be processed. The two insert halves guided to each other in this way can be respectively slid into the guide grooves of the relevant jaws and can be moved between different operating positions in the guide grooves. Different operating positions can be fastened by latching connections. In each different operating position, the half mold pair is coaxially arranged on the central axis of the tool, thereby producing symmetrical force conditions and good support. The guide grooves as well as the displacement freedom of the tool insertion structure and the insert halves are oriented transversely to the processing axis of the crimping tool and in the jaw plane in which the handle pivots and the relative movement of the jaws takes place.

[0003] EP0468335A2 discloses a crimping pliers, by which a plug is crimped to a cable in two axial sections. In the first axial section, a so-called insulation crimp is produced, in which region the plug is crimped to the insulating sheath of the conductor. In the second axial section, a so-called conductor crimp is produced, by which the plug is crimped to the conductor end of the cable, in which region the insulating sheath of the cable has been removed by stripping. The insulation crimp on one side and the conductor crimp on the other side use different synchronously actuated half-die axial sections. According to EP0468335A2, the half-die axial sections are formed by plates that are at a certain distance from each other and extend parallel to each other. The plate with the half-die axial sections of the fixed jaws can be rotatably mounted on the pliers head so that the half-die axial sections arranged on different edges of the plate can play a role. To this end, the plate is moved out of the side guide under the bias of a spring and then reinserted into the side guide after a rotation of 90° or 180°. EP0468335A2 also proposes that the plate held on the movable jaw can be rotated to different angular positions accordingly so that the axial sections of the half-molds formed on the movable jaw at different edges of the plate can play a role.

[0004] EP2463969B1 discloses a crimping pliers, wherein the two jaws each include a half mold arranged adjacent to each other, which form a half mold pair with different mold geometries. In order to simplify the insertion and alignment of the workpiece in the half mold, the crimping pliers has a locator or "stopper". The stopper is located next to the actual pliers head plane and in front of or behind the half mold. The end area of ​​the workpiece protruding from the pliers head in the stopper area can lean against the stopper formed by the stopper, thereby allowing the position of the workpiece in the half mold to be set. In addition, the end area is accommodated in the recess of the stopper by shape fit. The stopper may only include one such recess. In order to be able to use this recess for different half molds arranged adjacent to each other, the stopper may include a certain degree of displacement freedom, allowing the accommodation portion to be arranged behind the half mold pair to be used. Alternatively, EP2463969B1 proposes to implement the stopper as a rotator, which can rotate around an axis of rotation, and the axis of rotation is perpendicular to the pliers plane where the jaws and the handle move. In this case, the flat end face of the rotator associated with the tongs head comprises a plurality of receptacles having different geometries. In different rotational positions of the rotator, the end region of the workpiece can enter one of the receptacles of the rotator.

[0005] EP3984702A1 discloses a crimping pliers, wherein two half-die units are held on the jaws. Each half-die unit has a half-die with ribs, which can be moved relative to each other in the direction of the crimping axis. The half-dies are fixed to the support of the half-die units so that they can rotate around the crimping axis. According to the rotation of the half-dies around the crimping axis, the workpiece can be inserted into the receiving portion formed by the half-dies in different directions relative to the pliers head, and the workpiece can be crimped in these different directions.

[0006] US3094702A discloses crimping pliers. By using these crimping pliers, two axial sections of a plug can be processed by two pairs of half-dies arranged adjacent to each other and having different half-die profiles, in particular providing conductor crimping on the one hand and insulation crimping on the other hand. The two pairs of half-dies are guided together in the guide groove of the fixed jaw part along parallel crimping axes. The crimping movement of the half-die pair is due to the fact that the end of each half-die is supported on a cam surface, which is implemented as the inner surface of the actuating ring of the movable jaw part. The rotation of the movable jaw part relative to the fixed jaw part causes the relative rotation of the actuating ring, thereby causing the half-die to slide along the cam surface. In this way, the half-die pair is closed under the bias of the return spring, and the two axial sections of the connector are crimped simultaneously. The crimping pliers known from US3094702A have a limiter for assisting the insertion of the connector, and also have a forced locking unit for preventing the opening movement of the jaw part during the crimping stroke, and only allowing the opening movement after the crimping stroke is completed.

[0007] US2004 / 0093999A1 discloses pliers that can be used to strip the insulation of cables in the area of ​​the jaws. On the other hand, the pliers can also be used to crimp connectors. To this end, a barrel die comprising half dies with different half-die profiles is rotatably mounted relative to a fixed part of the pliers. The user can selectively transfer different half dies to a working position by manually rotating the barrel die. In the working position, a plug can be crimped between the half die in the working position and a punch actuated by a movable handle. The drive mechanism of the punch interacts with the corresponding half die that the user transfers to the working position by rotating the barrel die, which is not described in more detail in US2004 / 0093999A1.

[0008] CN116237421A discloses a machine tool for punching out battery casings of lithium-ion batteries. The machine tool has a workbench, and the sheet metal to be processed is placed on rollers. A tool barrel with a horizontally oriented axis of rotation has punching tools at the 12 o'clock position, the 3 o'clock position, the 6 o'clock position and the 9 o'clock position. The punching tool arranged at the 12 o'clock position is used to process the sheet metal. After the punching process using this punching tool, the tool barrel rotates so that the punching tool with the punched-out part of the sheet metal moves to the 6 o'clock position, where the punched-out part can fall due to gravity. The process of removing the punched-out part from the punching tool is assisted by a cam that actuates the punching tool. Four punching tools distributed in the circumference enable the machine tool to operate cyclically.

[0009] Further prior art is known from FR2217830A. Summary of the invention

[0010] The object of the present invention is to provide a multifunctional tool, in particular:

[0011] - achieve simplified operations, and / or

[0012] - No need to use a large number of different tools for machining different workpieces and / or different machining steps.

[0013] Furthermore, the object of the invention is to propose a tool set comprising two sub-sets of these tools, which set is improved in particular with regard to manufacturing, storage and component costs.

[0014] The object of the invention is solved according to the invention having the features of the independent patent claim. Further preferred embodiments of the invention can be found in the dependent claims.

[0015] The invention proposes a tool comprising two processing bodies. The processing bodies can be formed as one part or in multiple parts. To name a few examples, which do not limit the invention, the processing bodies can be half-molds, half-mold holders, peeling knives, peeling knife holders, cutting knives or cutting knife holders.

[0016] The processing bodies together form a receptacle for the workpiece. For example, if the processing bodies are mold halves, the processing bodies together form a mold through which the workpiece is pressed. A receptacle is then formed between the mold halves into which the workpiece can be inserted and pressed.

[0017] The receiving portion includes a longitudinal axis. The workpiece can be inserted into the receiving portion along the longitudinal axis direction and can be removed from the receiving portion along the longitudinal axis direction after pressing. The longitudinal axis of the receiving portion is defined by the opening defined by the processing body for inserting the workpiece and the contour of the processing surface of the processing body. For the above-mentioned half-mold example, the inner surface of the half-mold pressed against the workpiece (especially the plug in which the cable is arranged) defines the longitudinal axis.

[0018] The two processing bodies can be moved between an open position and a closed position (and vice versa). During the movement from the open position into the closed position, the workpiece is processed. Here, the processing bodies are moved relative to each other by a processing stroke along a processing axis, which is oriented radially to the longitudinal axis of the receptacle for the workpiece. Due to this radial orientation, the movement of the processing bodies from the open position into the closed position results in the workpiece being processed between the processing bodies. In the context of the present invention, "processing" refers in particular to pressing, crimping, cutting into or cutting the workpiece.

[0019] The processing bodies contain a common rotational degree of freedom, since they can be rotated together about a rotation axis (at least) from a first rotational position to a second rotational position. The rotation axis is preferably oriented perpendicularly to the tool head plane, the plane of movement of the handle and / or the plane of movement of the tool jaws. Alternatively, the rotation axis can be oriented parallel to the longitudinal axis of the receptacle and at a distance therefrom.

[0020] By means of such a rotation about the axis of rotation between the rotational positions, the machining axis of the machining body can be transferred exclusively from a first relative position into a second relative position and / or from a first orientation into a second orientation.

[0021] According to the invention, in different rotational positions, different pairs of working bodies can be activated and actuated by the tool actuation unit.

[0022] There are various options for providing the rotatability about the axis of rotation and different rotational positions. For example, a certain type of pivot bearing can provide the rotational freedom. The processing body (which can be a component of the tool insertion structure or located in the housing of the tool insertion structure) can also be inserted into the receiving part of the tool actuation unit in different orientations corresponding to the rotational positions and can be fixed therein (for example, basically corresponding to inserting a plate in its guide in different orientations according to EP0468335A2).

[0023] There are different options for the alignment of the machining axis along which the two machining bodies can be moved relative to each other. For one option, the machining axis extends parallel to the axis of rotation. In this case, a change in position can be brought about by rotating the machining body from a first rotational position to a second rotational position. Preferably, however, the machining axis is oriented radially to the axis of rotation. In this case, a rotation of the machining body about the axis of rotation from a first rotational position to a second rotational position results in a change in orientation of the machining axis (i.e. a change in angle).

[0024] It is also possible to rotate a plurality of processing body pairs jointly between different rotational positions.

[0025] The tool has a rotating body, also called a rotator, which is preferably drum-shaped or cylindrical in the first approximation. The rotator can be any rotatable component or rotatable structural unit. The rotator can rotate around an axis of rotation. The rotator includes at least two processing body pairs. In one embodiment, the processing body pair includes processing axes oriented in different directions radially to the axis of rotation. In this case, the sequential transfer of different processing body pairs to the same position and / or orientation can be achieved by rotating the rotator to different rotational positions, wherein the actuating plunger of the tool actuating unit and the corresponding processing body pair can interact in this position and orientation.

[0026] The rotational freedom of the processing body and the rotator can be realized in steps or in a stepless manner.

[0027] In one embodiment, a fixing device is provided. By means of the fixing device, the rotational position of the processing body or the rotator brought into by the user can be fixed. This allows the working position of the processing body or the rotator to be secured, which can be suitable for the operation of the tool or can also be advantageous for storing the tool in a tool box. During operation of the tool, the fixing device can also support part of the forces acting between the workpiece and the processing body to prevent the processing body or the rotator from being accidentally rotated about the rotation axis due to these forces.

[0028] Within the scope of the invention, the fixing device can be designed in various ways. For example, the fixing device can be a threaded connection or a clamping connection.

[0029] In one embodiment, the fixing device is a latching device. In the case of a latching device, latching and / or unlocking is preferably performed by applying a sufficient rotational force to a rotator or a processed body fastened by the latching device. Preferably, the latching device comprises a latching element, which is spring-loaded and engages in a latching recess for latching. The inclination of the contact surface between the latching element and the latching recess, the preload of the spring acting on the latching element and / or the stiffness of the latching spring can be used to set the rotational force when the latching device is released.

[0030] However, the fixing device may also be a locking device. Such a locking device preferably makes it impossible to release the locking device by applying a rotational force or a machining force to the rotator alone. Instead, the movement of a separate locking element is absolutely necessary to unlock the locking device, which must be achieved by a separate manual actuation of the locking element.

[0031] Combinations of latching and locking devices are also possible, wherein the structural elements latch to one another in one direction of movement, while in another direction of movement they lock to one another.

[0032] The tool comprises a tool insertion structure and a tool actuation unit. The tool insertion structure then comprises a rotator with at least two pairs of processing bodies. The tool actuation unit comprises an actuation plunger. The tool actuation unit can move and generate an actuation force for the actuation plunger in a variety of different ways. For example, the tool actuation unit can have a handle to which a user can apply manual force, which is then converted into an actuation force for the actuation plunger in combination with an acceleration ratio or a reduction ratio (using a suitable transmission mechanism). However, the actuation force for the actuation plunger may also be generated by an electric, pneumatic or hydraulic actuator.

[0033] The tool actuation unit comprises a housing, which is preferably arranged in the area of ​​a fixed tool jaw or a movable tool jaw or a tool head. A tool insertion structure (permanently or replaceably and / or directly) can then be inserted into the housing. To name just a few examples, the rotator can be directly inserted into the housing and the outer surface can be rotatably mounted relative to the inner surface of the housing, or the inner surface can be rotatably mounted relative to the bearing journal of the housing. However, the tool insertion structure can also include a housing in which the rotator is rotatably mounted. In this case, the housing is subsequently inserted into the housing. The housing can then be permanently or replaceably connected to the tool jaws of the tool actuation unit.

[0034] The actuation force is transmitted between the tool actuation unit and the tool insertion structure by contact between the actuation surface of the actuation plunger and the actuation surface of one of the processing bodies in the processing body pair, which is activated at a selected rotational position and is preferably a mobile processing body in the processing body pair. If the rotator is in a first rotational position, the first processing body pair establishes contact with the actuation surface of the actuation plunger. If the rotator is rotated to a second rotational position, the processing surface of the first processing body pair is removed from the actuation surface of the actuation plunger, and the corresponding actuation surface of the second processing body pair forms an operational connection with the actuation surface of the actuation plunger. The actuation surfaces can be loosely relative to each other, which makes the rotational movement of the rotator possible. In the case where the actuation force is not generated by the tool actuation unit, the preload of the spring can ensure the basic contact pressure between the actuation surfaces. However, when the tool actuation unit does not generate an actuation force, the actuation surfaces may also be spaced apart from each other by a gap.

[0035] The basic design of the tool actuating unit has a wide range of possibilities, so that all different types of tool actuating units known from the prior art can be used.

[0036] In one embodiment, the tool actuation unit is a crimping machine actuation unit, so that the rotation of at least one processing body pair can be used for a stationary crimping machine.

[0037] For another solution, the tool actuation unit is a manual pliers actuation unit, in particular comprising a handle, by means of which the tool can be manually operated. For example, the tool is then embodied as a crimping pliers, which, depending on the configuration of the processing body, can crimp different workpieces in different rotational positions and / or can provide additional processing operations (in particular cutting and / or slitting for stripping).

[0038] When the tool actuating unit is designed as a manual pliers actuating unit, the following options are preferably provided:

[0039] For the first embodiment, the manual pliers actuation unit has a base body, which integrally forms the handle and the actuation plunger. The movement of the handle brings about the actuation stroke, and the movement of the handle is converted into the movement of the actuation plunger, requiring the traditional manual pliers actuation unit to connect multiple components (especially bars or rods) to each other through a rotary joint to form a transmission mechanism, which is disadvantageous in terms of size, construction workload, component diversity and assembly. For the one-piece design of the base body, the relative movement of at least one handle relative to the actuation plunger on the processing stroke is provided by the inherent elasticity of the base body and the deformation of the base body. Although the component design of the above-mentioned manual pliers actuation unit of the prior art is as hard as possible by using a rotary joint, the elastic member (in this case, an elastic base body) can also be used specifically for this solution, which makes it possible to use elastic materials. For example, the base body can be made of plastic material, especially in an injection molding process or an additive manufacturing process, wherein the plastic can also be reinforced with fibers. Other materials that can be used include biomaterials, growing raw materials, compostable materials and / or recyclable materials. Just to give a non-limiting example, such a manual pliers actuation unit may be embodied as shown and described in DE 20 20 23 000 293 U1. Preferably, the manual pliers actuation unit is free of any pivot bearing.

[0040] For a second embodiment, the manual pliers actuation unit comprises a fixed tool part with a fixed tool jaw and a fixed handle. In addition, the manual pliers actuation unit comprises a movable handle. The manual pliers actuation unit also comprises a movable tool jaw and a pressure rod. In this case, the movable tool jaw is hinged to the fixed tool part via a rotary joint. The movable handle is connected to the movable tool jaw via a rotary joint. The pressure rod is connected to the fixed tool part via a rotary joint (in one end region) and to the movable handle via a rotary joint (in the other end region). In the manual pliers actuation unit, a toggle lever drive is formed by a pressure rod forming a first toggle lever and a part of a movable handle forming a second toggle lever. The rotary joint at which the pressure rod is connected to the movable handle forms a toggle joint in the toggle lever drive. For this embodiment, one tool jaw (particularly a movable tool jaw [or a fixed tool jaw]) forms a receiving portion for a tool insertion structure. Then, the other tool jaw (the fixed tool jaw [or the movable tool jaw]) contains or supports an actuating plunger. Thus, as described above, the proposed measures for providing a rotational degree of freedom of the processing body can be integrated into a basic known manual pliers actuation unit or crimping or pressing pliers with a toggle lever drive as described above. For example, it can be integrated into the crimping or pressing pliers described in DE19802287C1.

[0041] For the third embodiment, the manual pliers actuating unit has a fixed tool part, which includes a C-shaped tool head and a fixed handle. In this case, the C-shaped tool head forms a fixed tool jaw. The manual pliers actuating unit also has a sliding body, which is guided on the tool head so that it can move in translation and form a movable tool jaw. The manual pliers actuating unit also includes a pressure rod and a movable handle. In the manual pliers actuating unit, the pressure rod is connected to the fixed tool part by a rotary joint (in one end area) and to the movable handle by a rotary joint (in the other end area). The movable handle is hinged to the sliding body by a rotary joint. A toggle lever drive is formed by the pressure rod forming the first toggle lever and the part of the movable handle forming the second toggle lever. Then, the rotary joint at which the pressure rod is connected to the movable handle forms an elbow joint in the toggle lever drive device. One tool jaw (movable tool jaw [or fixed tool jaw]) forms a receptacle for a tool insertion arrangement or supports it, while the other tool jaw (fixed tool jaw [or movable tool jaw]) comprises an actuating plunger or supports it. Thus, for example, the proposed measures can also be integrated into crimping pliers with a drive mechanism as shown and described in principle in DE 198 07 737 C2.

[0042] For the fourth embodiment, the manual pliers actuation unit may include an O-shaped tool head forming a fixed tool jaw. The sliding body is guided on the tool head to produce a translational displacement. The sliding body forms a movable tool jaw. Two movable handles are connected to each other by a rotary joint (similar to a pair of scissors). The manual pliers actuation unit has two pull rods for this fourth embodiment. Each pull rod is connected to the relevant handle by a rotary joint in one end region and to the tool head by a rotary joint in the other end region. Then, the pivot pin of the rotary joint connecting the two handles to each other is arranged in the accommodating portion of the sliding body. Then, the actuating force generated by the handle can be transmitted to the sliding body through the contact of the pivot pin with the sliding body. For example, for the fourth embodiment, the proposed measures can be integrated into a crimping pliers described in the public documents DE10056900C1 and EP0468335A2.

[0043] As mentioned above, a fixed or replaceable connection can be used between the tool insertion structure and the receiving part of the tool actuation unit. In principle, the connection options known in the prior art can be used for replaceable components of the tool insertion structure and the receiving part of the tool actuation unit. For one embodiment, the tool jaws include a recess with open edges. Then, the tool insertion structure includes a transverse carrier. In order to support the tool insertion structure on the tool jaws in a replaceable manner, the transverse carrier is arranged in the recess. Then, the tool insertion structure and the transverse carrier can be disassembled by simply removing the tool insertion structure and the transverse carrier from the recess. Additional coupling or connection measures can be used between the tool insertion structure and the receiving part of the tool actuation unit, in particular additional fixing screws and / or further support of the second transverse carrier in the second recess with open edges. The interaction of (at least one) transverse carrier with (at least one) recess is used to provide force transmission and support and / or fastening to prevent displacement and / or rotation. The corresponding support between at least one transverse carrier and at least one recess with open edges can also be used to support the housing of the actuating plunger or tool insertion structure on the tool jaws.

[0044] For the above-described embodiments, the tool jaws may have two parallel and spaced-apart tool jaw plates, which include an open-edged recess or preferably two spaced-apart open-edged recesses facing one side of the tool or jaws. In this case, the tool insertion structure, the actuating plunger or the housing of the tool insertion structure may include a flange, which is arranged in the intermediate space between the tool jaw plates and is therefore guided and supported between the tool jaw plates. The tool insertion structure, the actuating plunger or the housing of the tool insertion structure may then include one or two transverse carriers, by means of which additional support and fixation is provided to prevent displacement or rotation. Preferably, the replaceable connection of the housing of the tool insertion structure, the actuating plunger or the tool insertion structure is provided by transverse screws and recesses in the same manner as described in DE19802287C1 (although it is used for the support of conventional half-molds on the tool jaws).

[0045] In a tool set, the tools can be implemented as described above. In one embodiment, the group of tools includes two subgroups, namely a first subgroup and a second subgroup. Then, the tools in the first subgroup and the second subgroup include different types of tool actuation units. For example, the tools in the first subgroup may include a tool actuation unit implemented as a crimping machine actuation unit, while the tools in the second subgroup may include a tool actuation unit implemented as a manual pliers actuation unit. It is also possible that the tools of different subgroups are implemented as different types of manual pliers actuation units. Then, the tools of different subgroups can be used for different purposes. Although the design of the tool actuation unit is different, the tools of the two subgroups may include the same tool insertion structure. In this way, the types of component parts or components can be reduced, which is advantageous in terms of manufacturing, inventory and supply costs.

[0078] In the following description of the figures, some components and features that correspond or are similar in design and / or function are marked with the same reference numerals. In this case, additional letters a, b, ... may be added for identification. These components and features can then be referenced with or without additional letters, i.e., one component or feature, a plurality of components or features, or all components or features can be referenced.

[0079] Figure 1 A tool 1 is shown with a base body 2 . The base body 2 forms a receptacle 3 for a tool insertion structure 4 .

[0080] The base body 2 forms a tool head 5, which includes the receiving portion 3. A handle 6, 7 extends from the tool head 5. Figure 1 In the embodiment shown, they are oriented approximately parallel to one another (this is not necessarily the case). In the end region facing away from the tool head 5, pressure rods 8, 9 are formed on the handles 6, 7, which extend toward the tool head 5 at an acute angle relative to the associated handle 6, 7. The two pressure rods 8, 9 extend relative to one another in a V-shape in the direction toward the tool head 5 and are firmly connected to one another in the connecting region of the legs of the V, i.e. in the end that is arranged closest to the tool head 5. The connecting region of the pressure rods 8, 9 forms an actuating plunger 10. The actuating plunger 10 comprises an actuating surface 11 on the side facing the tool head 5 and the tool insertion structure 4.

[0081] The tool 1 has a cover 12 or a cap (hereinafter referred to as cover 12), which is screwed onto the basic body 2 in the region of the tool head 5 using a fastening screw 35. The receptacle 3 forms an interior space between the basic body 2 and the cover 12.

[0082] Figure 2 , in which the cover plate 12 is removed. The tool insertion structure 4 has a rotator housing 13, which is arranged in an inner space delimited by the receiving portion 3 and the cover plate. The rotator housing 13 has a cylindrical outer surface 14, which forms a guide portion 15, by which the rotator housing 13 is rotatably guided on a corresponding cylindrical inner surface of the tool head 5 formed by the receiving portion 3, so that the rotator housing 13 is guided to rotate relative to the tool head 5 about a rotation axis 16. Alternatively or additionally, the rotator housing 13 may include a hole 17 forming the guide portion 15. The guide portion 15 can then provide for the rotation of the rotator housing 13 and the tool insertion structure 4 about the rotation axis 16, because the pin 18 formed by the cover plate 12 is guided in the guide portion 15 (see Figure 4 ).

[0083] In the example shown, the tool insertion arrangement 4 has three processing body pairs 19 a , 20 a ; 19 b , 20 b ; and 19 c , 20 c .

[0084] In the embodiment shown, the processing body 19 is embodied as a processing body that is movable in the processing stroke, while the processing body 20 is embodied as a processing body that is fixed in the processing stroke. The movable processing body 19 is movable relative to the fixed processing body 20 along a processing axis 21. The processing bodies 19, 20 are distributed in the circumferential direction around the rotation axis 16 so that they are arranged in the 2 o'clock position, the 6 o'clock position and the 10 o'clock position, respectively. The processing axes 21a, 21b, 21c are oriented radially to the rotation axis 16 and are mutually offset by 120° in the circumferential direction. The movement of the movable processing body 19 causes the loading of at least one spring 22, 23.

[0085] The fixed machining body 20 is permanently mounted on or formed by the rotator housing 13. The movable machining body 19 is guided in the direction of the machining axis 21 by means of guides provided by the rotator housing 13. For the illustrated embodiment, the guides for the movable machining body 19 are implemented as ribs of the rotator housing 13.

[0086] On the side facing away from the fixed processing body 20, the movable processing body 19 has a projection 24, which forms an actuation surface 25 for interacting with the actuation surface 11 of the actuation plunger 10. For this purpose, the rotator housing 13 has an opening 26 in the guide 15, through which the actuation plunger 10 and / or the projection 24 can extend. The rotator housing 13 has blind holes 27 arranged parallel to the rotation axis 16, distributed in the circumferential direction of the rotation axis and located radially inside the processing body 20.

[0087] exist Figure 3 In particular, it can be seen that the latch springs 28 are inserted into the blind holes 27 so that they are supported at one spring base by the bottom of the blind holes 27. The other spring base of the latch spring 28 is biased against the latch element 29, which is implemented as a latching ball 30. In the first, second and third rotational position of the rotator housing 13, the latch element 29 latches in a latching recess 31 (which can be implemented as a blind hole) of the cover plate 12. Here, in the first rotational position (as shown in FIG. Figure 5 ), the processing body pair 19a, 20a is aligned with the processing axis 21a so that the protrusion 24a of the processing body 19a can interact with the actuating plunger 10 of the base body 2. In the second rotational position, one processing body pair 19b, 20b can then be arranged to interact with the actuating plunger 10, while correspondingly in the third rotational position, one processing body pair 19c, 20c can interact with the actuating plunger 10.

[0088] For the embodiment shown, the rotator housing 13 is roughly mushroom-shaped, the mushroom head of the rotator housing 13 forming the outer surface 14 with the guide 15, and the processing bodies 19, 20 are arranged inside the mushroom head with the springs 22, 23 and the projection 24. The mushroom stem of the rotator housing 13 forms an actuation extension 32, which is essentially cylindrical here. The actuation extension 32 extends out of the housing 13 and the base body 2 on the side facing away from the cover plate 12. The actuation extension 32 includes a knurling 33. The user can rotate the actuation extension 33 with his fingers in the area of ​​the knurling 33, which allows the user to change the rotational position. When the latching element 29 engages with the latching recess 31, the user receives a tactile feedback. The mushroom head of the rotator housing 13 is axially clamped between the cover plate 12 and the bottom 34 formed by the base body 2.

[0089] Figure 5 As shown, the processing body pairs 19 and 20 are designed for different types of processing. For example, in the first processing body pair, the processing bodies 19a and 20a are implemented as half-molds 36 and 37, which can be used to crimp the connector to the cable. The processing bodies 19b and 20b in the second processing body pair have cutting knives 38 and 39, respectively, which include straight cutting edges and can be used to cut workpieces or cables. The processing bodies 19c and 20c in the third processing body pair have cutting knives 40 and 41, respectively, whose cutting edges are approximately semicircular, for cutting into the insulation sheath of the cable for stripping.

[0090] The operation of tool 1 is as follows Figures 1 to 5 As shown below:

[0091] Initially, the processing body pair 19a, 20a is located in the region of the opening 26, whereby the processing axes 21a of these processing bodies 19a, 20a are oriented coaxially to the actuation axis of the actuation plunger 10. Initially, a gap 42 is formed between the actuation surface 11 of the actuation plunger 10 and the actuation surface 25a of the projection 24a of the processing body 19a. If the user then applies a manual force to the handles 6, 7 so that the base body 2 is elastically deformed so that the end regions of the handles 6, 7 facing away from the tool head 5 move relative to each other, this leads to a movement of the actuation plunger 10 in the direction of the processing axis 21a. As a result of this movement, the gap 42 is closed and the actuation plunger 10 abuts with the actuation surface 11 against the actuation surface 25a of the projection 24a of the processing body 19a. A further increase in the force exerted by the hand on the handles 6, 7 leads to the actuation plunger 10 applying an actuation force to the processing body 19a via the actuation surfaces 11, 25a. This actuation force in turn moves the machining body 19a in the direction towards the machining body 20a, resulting in the workpiece being machined. Once the machining is completed, the force exerted by the hand on the handles 6, 7 is removed, so that due to the action of the springs 22a, 23a, the machining bodies 19a, 20a are separated again, and the actuation plunger 10 is moved away from the tool head 5 in the direction of the machining axis 31, and the gap 42 is re-established. Then, more workpieces can be machined continuously in a corresponding manner using the machining bodies 19a, 20a.

[0092] On the other hand, if it is necessary to cut the workpiece, the tool insertion structure 4 is rotated so that the protrusion 24b of the processing body 19b is arranged in the effective area of ​​the actuating plunger 10. Figure 5 In the embodiment, it can be realized by rotating 120 ° counterclockwise. If the handles 6 and 7 are manually operated now, the workpiece can be cut between the cutting knives 38 and 39 of the processing bodies 19b and 20b.

[0093] If the cable is to be stripped, the rotator housing 13 is rotated again so that the projection 24c of the machining body 19c is arranged in the effective area of ​​the actuating plunger 10, which can be done by pulling it from the Figure 5 The rotational position shown is achieved by rotating 240° counterclockwise. The cutting stroke of the cutting blades 40, 41 into the insulating sheath of the cable can then also be achieved by actuating the handles 6, 7 and transmitting the actuation force generated in this way from the actuation plunger 10 via the actuation surfaces 11, 25c to the processing body 19c.

[0094] For example, in different rotational positions of the tool insertion structure 4, firstly by Figure 5 The processing bodies 19b and 20b in the cable are cut into required lengths, and then the end regions of the cable are stripped by the processing bodies 19c and 20c. Finally, the connectors are crimped onto the stripped end regions of the cable by the processing bodies 19a and 20a.

[0095] Figures 6 to 9 Another embodiment of a tool 1 is shown. The tool 1 comprises a fixed tool part 43 forming a fixed handle 44 and a fixed tool jaw 45. The tool 1 further comprises a movable handle 46, a pressure bar 47 and a movable tool jaw 48.

[0096] The pressure rod 47 is connected to the fixed tool part 43 in a rotary joint 49 in one end region. In the other end region, the pressure rod 47 is connected to the movable handle 46 via a rotary joint 50. In the region of the fixed tool jaws 45, the fixed tool part 43 is connected to the movable tool jaws 48 via a rotary joint 51. The movable handle 46 is connected to the movable tool jaws 48 via a rotary joint 52. The tool 1 includes a toggle lever drive 53. In the toggle lever drive 53, the rotary joint 50 forms a toggle joint 54. The first toggle lever 55 is formed by the section of the pressure rod 47 between the rotary joints 49, 50. The second toggle lever 56 is formed by the section of the movable handle 46 between the rotary joints 50, 52. Crimping pliers with a drive kinematic mechanism and a toggle lever drive 53 of this type are in principle known from DE19802287C1.

[0097] The fixed tool jaw 45 forms a receiving portion 3 for the tool insertion structure 4. The fixed tool part 43 comprises two parallel and spaced apart tool plates 57, 58. The movable tool jaw 48, the movable handle 46 and the pressure rod 47 are arranged and guided between the tool plates 57, 58. The tool plates 57, 58 each have a bearing lug 59, 60 to form the receiving portion 3.

[0098] Currently, the tool is inserted into the structure 4 as Figures 1 to 5 Here, however, the cover plate 12 is not attached to the fixed tool jaws 45, but to the rotator housing 13, so that the cover plate 12 rotates together with the rotator housing 13 about the rotation axis 16 between rotation positions. The cover plate 12 has three groove-shaped continuous recesses 61a, 61b, 61c extending from the outer surface and extending radially inwards, which are arranged in alignment with the associated processing pairs 19, 20 when the cover plate 12 is mounted on the rotator housing 13. Thus, the receiving portion 62 formed by the processing pair 19, 20 can be accessed, into which the workpiece can be inserted.

[0099] The outer surface of the cover plate 12 in the shape of a cylindrical section forms a guide 15 for guiding the rotation of the tool insertion structure 4 about the rotation axis 16. The outer surface of the cover plate 12 in the shape of a cylindrical section forming the guide 15 is received with an exact fit in the bearing lug 59. In a corresponding manner, the rotator housing 13 can be guided in the bearing lug 60 by means of a shoulder or a guide surface.

[0100] The tool insert structure 4 is axially secured between the tool plates 57 , 58 , since the rotator housing 13 is axially captured between the limits of the bearing lugs 59 , 60 .

[0101] In the illustrated embodiment, the outer surface of the fixed tool jaw 45 is formed on the one hand by the outer surfaces of the tool plates 57 , 58 in the region of the bearing lugs 59 , 60 and between them by the outer surface of the rotator housing 13 .

[0102] For according to Figures 6 to 9 In the embodiment of the movable tool jaw 48, the actuating plunger 10 is not a component of the movable tool jaw 48, but is a separate, removable and replaceable part of the movable handle 46. The actuating plunger insert 63 integrally forms the actuating plunger 10, and the flange 64 forms the base of the actuating plunger 10. Two pin-shaped transverse carriers 65a, 65b extend parallel to each other on both sides of the flange 46. Although in principle it is possible to embody the transverse carriers 65 as a component of the actuating plunger insert 63, they are preferably bolts that are inserted or pressed into holes in the flange 24. In addition, the flange 64 has a hole 66.

[0103] On the upper side of the two parallel tool jaw plates 67a, 67b facing the fixed tool jaw 45, the movable tool jaw 48 has open-edged recesses 68a, 68b, the distance between which corresponds to the distance between the transverse carriers 65a, 65b.

[0104] In order to mount the actuating plunger insert 63 on the movable tool jaw 48, the flange 64 is inserted between the tool jaw plates 67a, 67b. The transverse carrier 65 abuts against the recess 68 of the tool jaw plate 67, so that the actuating plunger insert 63 is supported by the actuating force by the transverse carrier 65 abutting against the recess 68 of the tool jaw plate 67. The support of the transverse carrier 65 in the recess 68 also ensures the desired orientation of the actuating plunger insert 63 and thus the desired orientation of the actuating plunger 10. The actuating plunger insert 63 can be additionally fastened to the movable tool jaw 48 by screwing the movable tool jaw 48 onto the actuating plunger insert 63 by means of a fixing screw 69 which protrudes through a hole 66 of the flange 64. Preferably, the hole 66 is larger in relation to the size of the fixing screw 69, so that the position of the actuating plunger 63 relative to the movable tool jaw 48 is not defined by the fixing screw 69, but by the transverse carrier 65.

[0105] During operation of the tool 1, the actuating plunger 10 extends through the opening 26 of the rotator housing 13 between the limits of the bearing lugs 59, 60 into the interior of the tool insertion structure 4, and then the actuating plunger 10 interacts with its actuating surface 11 in the described manner with the corresponding actuating surface 25 of the corresponding processing body 20. In principle, the support of the actuating plunger insert 63 in the recess 68 of the tool jaw 48 by the transverse carrier 65 corresponds to the connection described in DE 198 02 287 C1. For more details in this regard, reference is made to this publication.

[0106] Figures 10 to 13 Another type of tool 1 is shown, namely a crimping pliers 111:

[0107] In this case, the fixed tool part 43 forms a C-shaped tool head 70 with the fixed tool jaws 45 and the fixed handle 44. For the present embodiment, the sliding body 71 is guided translationally on the fixed tool part 43. The sliding body 71 forms the movable tool jaws 48. In this case, the movable handle 43 is connected to the sliding body 71 via a rotary joint 72 in the end area facing the tool head 70. Here, the rotating pin 73 of the rotary joint 72 can be guided in the bar-shaped hole 74 of the fixed tool part 43 to ensure the translational degree of freedom of movement. The pressure rod 74 is connected to the fixed tool part 43 in the rotary joint 75 and to the movable handle 46 in the rotary joint 76. The toggle lever drive is formed in a corresponding manner as described in the above embodiment.

[0108] For more information on the basic design of such a tool 1, reference is made to EP 2 096 725 B1 or to the crimping pliers sold by the applicant under the label "CS30".

[0109] Also for this embodiment, the fixing tool part 43 also has two tool plates 57, 58 and bearing lugs 59, 60, in which the tool insertion structure 4 is located. In this regard, please refer to Figures 6 to 9 Description of the embodiments in .

[0110] Here too, the tool 1 has a replaceable actuating plunger insert 63 , the embodiment of which has been described above. The transverse carrier 65 of the actuating plunger insert 63 is supported here on a recess 68 formed by two sliding plates 76 a , 76 b of the sliding body 71 .

[0111] Figures 14 to 16 The tool 1 is shown as a crimping pliers 111, wherein the basic structure of the drive mechanism corresponds to Figures 6 to 9In this case, the tool 1 has both a tool insertion structure 4 replaceably mounted in a fixed tool jaw 45 and an actuating plunger insert 63 replaceably mounted on a movable tool jaw 48. Both the movable tool jaw 48 and the fixed tool jaw 45 have parallel plates with recesses 68a, 68b. Accordingly, the actuating plunger insert 63 and the tool insertion structure 4 have a transverse carrier 65, a hole 66 and a flange 64.

[0112] In this way, the tool insertion structure 4 can be introduced with its flange 64 between the tool plates 57, 58 and the tool insertion structure 4 can be supported by a transverse carrier 65 located in a recess 68 of the tool plates 57, 58. Additional fastening is then provided by a fixing screw 69 extending through a hole 66 of the tool insertion structure 4.

[0113] The actuating plunger insert 63 is supported on the movable tool jaw 48 in that the flange 64 is arranged between the plates of the movable tool jaw 48. The transverse carrier 65 of the actuating plunger insert 63 is supported in a recess 68 of the plate. Here, too, additional fastening is provided by a fixing screw 69 which extends through a hole 66 of the actuating plunger insert 63.

[0114] Figures 17 to 20 The tool insertion structure 4 and the actuating plunger insert 63 are shown as separate components. For the present embodiment, the tool insertion structure 4 is not inserted directly into the housing 3 formed by the fixed tool jaws 45. Instead, the tool insertion structure 4 has a housing 78 in which the rotator housing 13 is rotatably mounted. The housing 78 comprises a transverse carrier 65, a flange 64 and a hole 66, so that the previously described support is provided by locating the transverse carrier 65 in the recess 68 of the fixed tool jaws 45. The cover plate 12 of the tool insertion structure 4 is then screwed onto the housing 78. The above applies to the basic design of the tool insertion structure 4 and the actuating plunger insert 63, as well as their assembly with the tool jaws 45, 48. The cover plate 12 is arranged in a correspondingly shaped recess of the housing 78, so that the outer surface of the cover plate 12 is flush with the flange 64, so that the housing 78 can be inserted between the tool plates 57, 58 up to the area of ​​the cover plate 12.

[0115] Fig.21 A tool 1 is shown which is implemented as a crimping pliers 111 and comprises a C-shaped tool head 70, which is generally designed as Figures 10 to 13In the embodiment of the present invention, however, the tool insertion structure 4 is not mounted in the bearing lugs 59, 60 of the fixed tool jaws 45. Instead, for this embodiment, the fixed tool jaws 45 comprise a recess 68 in the area of ​​the tool plates 57, 58. The transverse carrier 65 of the housing 78 of the tool insertion structure 4 can then be supported in the recess 68. In the present embodiment, a replaceable actuating plunger insert 63 and a replaceable tool insertion structure 4 supported by the transverse carrier 65 are used. The design of the actuating plunger insert 63 and the tool insertion structure 4 may be different from the embodiment of the present invention. Figures 14 to 20 The tool insertion structure 4 and the tool insertion structure 63 described in the drawings are designed identically, so they can be used versatility-wise for different types of tools 1 .

[0116] Fig. 22 A further embodiment of a tool 1 embodied as a crimping pliers 111 is shown. In this case, the tool 1 has an O-shaped tool head 79, which consists of two parallel, spaced-apart tool head plates. In this case, the tool 1 has two movable handles 80, 81. The end regions of the handles 80, 81 facing the tool head 79 are directly connected to one another via a swivel joint 82. Furthermore, pull rods 83, 84 are connected to the handles 80, 81 via swivel joints, as shown in FIG. Fig. 22 As shown. The pull rods 83, 84 are connected to the tool head 79 via swivel joints 85, 86. The sliding body 87 is guided for translational movement on the tool head 79. In the embodiment shown, the sliding body 87 integrally forms the actuating plunger 10. On the side facing the handles 80, 81, the sliding body 87 comprises a housing 88, in which a swivel pin 89 of the swivel joint 82 is supported. If the handles 80, 81 are actuated in the direction toward closing, the swivel pin 89 transmits the actuating force via the housing 88 to the sliding body 87 and thus to the actuating plunger 10.

[0117] about Fig. 22 and 23 For the basic design of the tool 1 shown in FIG. 1 , reference may be made, for example, to publications DE 100 56 900 C1 and EP 0 468 335 A2.

[0118] For this embodiment, the tool insertion structure 4 is inserted directly into the tool head 79 and is clamped between the two plates of the tool head 79. The rotational movement of the tool insertion structure 4 can be guided in the inner surface of the support lug of the tool head 79 by the outer surface of the rotator housing 13 and / or the outer surface of the cover plate 12. An additional cover (not shown) can be Fig. 22 and 23 ) is attached to a tool head 79 which covers externally (except for access to the actuating plunger 10 and the correspondingly activated pair of processing bodies 19 , 20 ) the tool insertion structure 4 .

[0119] Fig.24An embodiment is shown in which the tool 1 is embodied as a crimping machine 90. The crimping machine 90 has a fixed tool jaw 45 (which in this case can also be referred to as an anvil) and a movable tool jaw 48 (which in this case can also be referred to as a punch). The crimping machine 90 has a guide unit insert 91 which has two guide parts 92, 93 (see Fig.25 , 26 ). The guide parts 92, 93 are guided relative to each other by guide pins 94, 95, so that the guide parts 92, 93 can only perform translational movements in the direction of the drive axis 96. Displacement sensors and / or sensors for sensing driving forces can be integrated in the crimping machine 90, the tool jaws 45, 48 or the guide parts 92, 93. More information in this regard can be found in the publication EP2698885B1.

[0120] The actuating plunger insert 63 is mounted directly on the guide member 93. The tool insertion structure 4 comprises a housing 78 mounted on the guide member 92.

[0121] The guide parts 92, 93 have T-shaped strip-shaped projections in the area for fastening to the tool jaws 45, 48. By means of these projections, the guide parts 92, 93 can be slid into correspondingly shaped T-shaped slots of the tool jaws 45, 48.

[0122] The housing 78 of the actuating plunger insert 63 and the tool insertion structure 4 has rib-like strip protrusions 97, 98 in the side surface area, which can be inserted vertically into corresponding vertical grooves (not shown in the figure) of the guide parts 92, 93. In addition, the tool insertion structure 4 can be fastened to the guide part 93, and on the other hand, the housing 78 can be fastened to the guide part 92 by an additional connection (especially bolts).

[0123] The actuating projection 32 can comprise longitudinal grooves 99 which extend parallel to the axis of rotation 16 and coaxially to the processing body pair 19 , 20 and by which the receptacles 62 formed by the processing bodies 19 , 20 can be accessed.

[0124] Furthermore, the tool can have a positive locking unit 100. The positive locking unit 100 serves to secure the configuration of the handles 44, 46 and the tool jaws 45, 48 which is reached after a portion of the working stroke in order to prevent an unwanted opening movement during the working stroke even if the actuating force, in particular the manual force exerted by the user on the handles 44, 46, is temporarily removed. Instead, the positive locking unit 100 ensures that the handles 44, 46 and the tool jaws 45, 48 can only be opened when the working stroke is completed. Fig. 9An exemplary design of the forced locking unit 100 is explained. Here, the pressure lever 47 has teeth 101. A blocking pawl 102, which is pivotally hinged to the movable handle 46 and biased by a spring 103, engages with the teeth 101. With the closing movement of the movable handle 46, the pawl 102 slides along the teeth 101 like a ratchet, and the pawl 102 blocks the opening movement. Once the operating stroke is completed, the pawl 102 rotates backward so that the other side of the blocking teeth of the pawl 102 interacts with the teeth 101, thereby allowing the pawl 102 to slide along the teeth 101 in a ratchet manner for opening movement.

[0125] For the embodiment shown, the tool insertion structure 4 is mounted on the fixed tool jaw 45, and the actuating plunger 63 is mounted on the movable tool jaw 48 (if applicable). The opposite assembly, that is, the tool insertion structure 4 is mounted on the movable tool jaw 48 and the actuating plunger insert 63 is mounted on the fixed tool jaw 45, is also possible.
