Description

TECHNICAL AREA OF INVENTION

[0001] The invention relates to a tool, according to the preamble of claim 1, which is used, for example, for cable assembly, wherein the tool can be used, for example, to crimp a connector to the cable and / or to cut or slit the cable and / or to strip the cable. The tool can be designed as a (stationary) machine tool that can be electrically, pneumatically, or hydraulically driven. The tool can also be a hand tool. In this case, the tool can be held by hand while the actuating force is generated electrically, pneumatically, or hydraulically. It is also possible for it to be a manually operated hand tool in which the actuating force is generated by one or two hands operating hand levers. STATE OF THE ART

[0002] EP 2 096 725 B1 describes a crimping tool intended for crimping a component, such as an electrical wire connector, a pipe fitting, a fitting, a cable lug, or similar item. EP 2 096 725 B1 describes known crimping tools in which crimping takes place between die halves held by the jaws of the tool. Several pairs of die halves with different cross-sections and / or contours can be arranged side by side on a single die body. A user of the crimping tool can then select a workpiece and crimp it into any of the pairs of die halves. This allows for crimping of different workpieces without requiring any modifications or replacement of the crimping tool.EP 2 096 725 B1 further describes as known that different tool inserts with different contours and cross-sections can be used in a tool actuation unit. The tool inserts can then be fixed to the jaws of the tool actuation unit via a snap-fit ​​connection. Finally, EP 2 096 725 B1 describes as known that the jaws of a pipe crimping tool each have a rotary die that is rotatably mounted about an axis of rotation on the associated jaw (cf. DE 196 287 52 A1). Several die halves with different contours and cross-sections are arranged around the circumference of the rotary die. To select a specific pair of die halves, the user must move the rotary dies into the corresponding rotational positions in which the selected specific die halves of this pair are opposite each other.In the rotational positions required for the respective operation of the specific die halves of the pair, the turning dies can each be locked by means of spring-loaded slides engaging in the turning dies. Against the background of this prior art, EP 2 092 725 B1 proposes that a tool insert is formed with two insert halves. The insert halves are guided to one another by guide pins in such a way that they are translationally displaceable relative to each other in the direction of a machining axis. Each insert half has several adjacent die halves with different contours and cross-sections, with the opposing die halves of the two insert halves forming pairs of die halves by means of which different types of workpieces can be machined.The two insert halves, guided together in this way, can each be inserted into a guide groove of an associated plier jaw and moved within the guide groove between different operating positions. Each operating position can be secured by a detent mechanism. In each operating position, a pair of die halves is arranged coaxially to a central axis of the tool, resulting in symmetrical force distribution and good support. The guide grooves, and thus the degree of freedom of movement of the tool insert and the insert halves, are oriented transversely to the machining axis of the crimping tool and lie in a plane of the pliers in which the hand levers pivot and the relative movement of the plier jaws occurs.

[0003] EP 0 468 335 A2 discloses a crimping tool for crimping a connector to a cable in two axial sections. In the first axial section, an insulation crimp is created, in which the connector is crimped to the conductor's insulation sheath. In the second axial section, a conductor crimp is produced, by which the connector is crimped to a conductor end of the cable where the cable's insulation sheath has been removed by stripping. Different die halves, actuated simultaneously, are used for the insulation crimp and the conductor crimp. According to EP 0 468 335 A2, the die halves are formed by spaced-apart, parallel plates.Plates with the die-half axial sections of the fixed jaw can be rotatably mounted on the jaw head in such a way that die-half axial sections arranged at different edges of a plate can be activated. For this purpose, the plate is moved out of lateral guides under spring tension and, after being rotated by 90° or 180°, is reinserted into the lateral guides. EP 0 468 335 A2 also proposes that a plate held on a movable jaw can be rotated at different angles in order to activate die-half axial sections formed at different edges of the plate on the movable jaw as well.

[0004] EP 2 463 969 B1 discloses a crimping tool in which the two jaws each have adjacent die halves, forming pairs of die halves with different die geometries. To simplify the insertion and alignment of the workpiece in the die halves, the crimping tool has a positioner or "locator." The locator is located next to the actual plier head plane and in front of or behind the die halves. An end portion of the workpiece protruding from the plier head in the area of ​​the locator can come into contact with a stop formed by the locator, thus defining the axial position of the workpiece in the die halves. Furthermore, the end portion can be positively engaged in a recess of the locator. It is possible that the locator has only one such recess.To enable the use of this recess for the different, adjacent die halves, the locator can have a degree of displacement freedom, allowing the receptacle to be positioned behind the respective pair of die halves to be used. Alternatively, EP 2 463 969 B1 proposes that the locator be designed as a turret rotatable about an axis of rotation oriented vertically to the plane of the jaws in which the jaws and hand levers move. In this case, the flat end face of the turret associated with the jaw head has several receptacles with different geometries. In the different rotational positions of the turret, the end of the workpiece can enter one of the turret's receptacles.

[0005] EP 3 984 702 A1 discloses a tool according to the preamble of claim 1, in particular a crimping tool in which two die half units are held on plier jaws. The die half units each have rib-shaped die halves that can be inserted into one another in the direction of a crimping axis. The die halves are rotatably held about the crimping axis on a bearing body of the die half unit. Depending on the rotation of the die half about the crimping axis, the workpiece can be inserted into the receptacle formed by the die halves in different orientations relative to the plier head, and the workpiece can be crimped in these different orientations.

[0006] US 3,094,702 A discloses a crimping tool by which two axial sections of a connector can be processed by two adjacent pairs of die halves with different die half contours, in particular to ensure a conductor crimp on the one hand and an insulation crimp on the other. The two pairs of die halves are guided together in a guide groove of a fixed plier part along parallel crimping axes. The crimping movement of the die half pairs is effected by the die halves bearing against cam surfaces formed by an inner surface of an actuating ring of the movable plier part.A pivoting of the movable jaw section relative to the fixed jaw section causes a relative rotation of the actuating ring, resulting in a sliding movement of the die halves along the cam surfaces. This movement, contrary to the action of the return springs, closes the pairs of die halves and simultaneously crimps the two axial sections of the connector. The crimping tool known from US 3,094,702 A features a locator to assist in inserting the connector and a locking mechanism that prevents the jaw sections from opening during the crimping stroke, allowing opening only after the crimping stroke has been completed.

[0007] US 2004 / 0093999 A1 discloses a pair of pliers which can be used to strip a cable in the jaw area and to crimp a connector. For this purpose, a die drum is rotatably mounted relative to a fixed part of the pliers. This die drum has die halves with different contours distributed around its circumference. The user can selectively rotate the die drum to move the different die halves into a working position. In this position, a connector can be crimped between the die half in the working position and a die ram, which is actuated by a movable hand lever.The drive mechanism for the die punch, which interacts with the respective die half moved into the working position by the user through rotation of the die drum, is not described in detail in US 2004 / 0093999 A1.

[0008] CN 116 237 421 A discloses a machine tool for punching out the casing of a lithium-ion battery. The machine tool has a workbench on which a sheet metal workpiece rests on rollers. A tool drum, whose axis of rotation is horizontally oriented, has punching tools at 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions. The punching tool located at the 12 o'clock position is used to process the sheet metal. After punching with this tool, the tool drum rotates such that the punching tool, with the punched-out portion of the sheet metal inside, is moved to the 6 o'clock position, where the punched-out portion can fall downwards due to gravity. This removal of the punched-out portion from the punching tool is assisted by a cam that actuates the punching tool.The four punching tools distributed around the circumference enable the machine tool to be operated in cycles.

[0009] Further state of the art is known from FR 2 217 830 A. TASK OF INVENTION

[0010] The present invention is based on the objective of proposing a tool which is designed to be multifunctional and in particular enables simplified operation and / or eliminates the need for a variety of different tools for machining different workpieces and / or for different machining operations.

[0011] Furthermore, the invention aims to propose a tooling insert for tool formation that offers corresponding advantages. Finally, the invention aims to propose a group of tools with two subgroups of these tools, which is improved, particularly with regard to manufacturing, storage, and component costs. SOLUTION

[0012] The object of the invention is achieved according to the invention by the features of the independent claims. Further preferred embodiments of the invention can be found in the dependent claims. DESCRIPTION OF THE INVENTION

[0013] The invention underlying the problem is solved by a tool comprising two machining elements. These machining elements can be designed as single or multiple parts. To name just a few examples that do not limit the invention, the machining elements can be a die half, a die half holder, a stripping knife, a stripping knife holder, a cutting knife, or a cutting knife holder.

[0014] The machining elements together form a fixture for a workpiece. If, for example, the machining elements are die halves, they together form a die with which the workpiece is pressed. The fixture is then formed between the die halves, into which the workpiece can be inserted and in which area the workpiece is pressed.

[0015] The fixture has a longitudinal axis. The workpiece can be inserted into the fixture along this longitudinal axis and, after pressing, can be removed again along the same axis. The longitudinal axis of the fixture is defined by the opening provided by the workpiece insert and by the contour of the workpiece's machining surfaces. In the aforementioned example of the die halves, the inner surfaces of the die halves, which are pressed against the workpiece (in particular, a connector with a cable inside), define the longitudinal axis.

[0016] In the tool according to the invention, the two machining bodies are movable between an open position and a closed position (and vice versa). Machining of the workpiece takes place during the movement from the open position to the closed position. Here, the machining bodies are moved relative to each other along a machining axis via a machining stroke, the machining axis being oriented radially to the longitudinal axis of the workpiece holder. As a result of this radial orientation, the movement of the machining bodies from the open position to the closed position causes the workpiece to be machined between the machining bodies. Within the scope of the invention, "machining" refers in particular to pressing, crimping, cutting, or through-cutting the workpiece.

[0017] According to the invention, it is proposed that the machining elements have a common degree of rotational freedom, in that the machining elements are jointly rotatable about a rotational axis (at least) from a first rotational position to a second rotational position. Preferably, the rotational axis is oriented vertically to the tool head plane, the plane of movement of the hand levers, and / or the plane of movement of the tool jaws. Alternatively, the rotational axis can be oriented parallel to the longitudinal axis of the holder at a distance from this longitudinal axis.

[0018] By means of this rotation around the axis of rotation between the rotation positions, the machining axis of the workpieces can then be selectively transferred from a first position to a second position and / or from a first orientation to a second orientation.

[0019] According to the invention, the different positions and / or orientations of the machining axis of the machining bodies can be used so that, in the first rotational position, the machining bodies are activated, allowing them to be actuated by a tool actuation unit of the tool, while in the second rotational position they are not activated, preventing the tool actuation unit from actuating the machining bodies. It is also possible to achieve different interactions between the tool actuation unit of the tool and the machining bodies in the different rotational positions. For example, it is possible that the machining bodies are driven with different kinematics and gear connections in the different rotational positions.Preferably, different pairs of machining bodies can be activated in the different rotational positions and actuated by the tool actuation unit.

[0020] The invention offers various possibilities for ensuring rotation about the axis of rotation and for different rotational positions. For example, a type of rotary bearing can guarantee the degree of rotational freedom. It is also possible for the machining elements, possibly as part of a tool insert or within a tool insert housing, to be inserted into and secured in a receptacle of a tool actuation unit in different orientations corresponding to the rotational positions (e.g., essentially in accordance with inserting the plates according to EP 0 468 335 A2 in different orientations into their guide).

[0021] The invention also provides for different orientations of the machining axis along which the two machining bodies are movable relative to each other. In one possibility, the machining axis extends parallel to the axis of rotation. In this case, rotating the machining bodies from the first to the second rotational position results in a change of position. Preferably, however, the machining axis is oriented radially to the axis of rotation. In this case, rotating the machining bodies about the axis of rotation from the first to the second rotational position leads to a change in the orientation (i.e., a change in the angle) of the machining axis.

[0022] Within the scope of the invention, only one pair of machining elements can be rotatable, as previously explained. It is also possible for several pairs of machining elements to be rotatable individually or together between different rotational positions. In this case, the pairs of machining elements can also be guided on a common turret housing, which can have any geometry.

[0023] According to the invention, the tool has a rotating body, also referred to as a turret, which is preferably, to a first approximation, drum-like or cylindrical. The turret can be any rotatable component or assembly. The turret is rotatable about the axis of rotation. The turret has at least two pairs of machining elements. In a preferred embodiment of the invention, the pairs of machining elements have machining axes that are oriented radially to the axis of rotation in different directions.In this case, by rotating the turrets into different rotational positions, the different pairs of machining bodies can be successively transferred into the same position and / or orientation, whereby an interaction of an actuating plunger of the tool actuation unit with the respective pair of machining bodies can then be brought about in this position and orientation.

[0024] Within the scope of the invention, the degree of rotational freedom of the machining bodies and, if applicable, the turret can enable rotation in steps or stepless rotation.

[0025] One aspect of the invention includes a locking device. This device allows the user to fix a rotational position of the machining elements or the turret. This secures the working position of the machining elements or the turret, which can be advantageous for operating the tool or for storing the tool, for example, in a toolbox. The locking device can also absorb some of the forces acting between the workpiece and the machining elements during tool operation, thus preventing unwanted rotation of the machining elements or the turret around the axis of rotation caused by these forces.

[0026] There are numerous possibilities for the design of the fixing device within the scope of the invention. For example, the fixing device can be a screw or clamp connection.

[0027] In a particular embodiment of the invention, the fixing device is designed as a detent device. With a detent device, locking and / or unlocking preferably occurs by applying sufficient rotational forces to the turret or the workpieces secured by the detent device. Preferably, the detent device has a detent element that is spring-loaded and engages in a detent recess to lock it. The rotational force required to release the detent device can be determined by the inclination of a contact surface between the detent element and the detent recess, the preload of the spring acting on the detent element, and / or the stiffness of the detent spring.

[0028] It is also possible, however, that the fixing device is designed as a locking device. Such a locking device preferably makes it impossible to release the locking device by applying rotational forces to the turret or by machining forces alone. Rather, unlocking the locking device necessarily requires the movement of a separate locking element, which must be brought about by a separate manual actuation of the locking element.

[0029] Combined latching and locking devices are also possible, in which the components are latched together in one direction of movement, while they are locked together in the other direction of movement.

[0030] In principle, the tool can have any configuration and structure. According to one embodiment of the invention, the tool comprises a tool insert and a tool actuation unit. The tool insert then includes at least one pair of machining elements or the turret. The tool actuation unit includes an actuating plunger. Within the tool actuation unit, movement and the generation of the actuating force for the plunger can occur in a variety of different ways. For example, the tool actuation unit can have hand levers onto which a user can apply manual force, which is then (using a suitable transmission mechanism) transferred to the actuating plunger via reduction or overdrive.It is also possible, however, for the actuating force of the actuating plunger to be generated by means of an electric, pneumatic, or hydraulic actuator. For this embodiment of the invention, the tool actuating unit has a receptacle, which is preferably arranged in the area of ​​a fixed or movable tool jaw or tool head. The tool insert (permanent or replaceable and / or directly) can then be inserted into this receptacle. To name just a few examples that do not limit the invention, the turret can be inserted directly into the receptacle and rotatably mounted with a cylindrical surface against an inner surface of the receptacle or with an inner surface against a bearing journal of the receptacle. It is also possible, however, for the tool insert to have a housing in which the turret is rotatably mounted. In this case, the housing is then inserted into the receptacle.The housing can then be permanently or interchangeably connected to a tool jaw of the tool actuation unit. An actuating force is transmitted between the tool actuation unit and the tool insert via contact between an actuating surface of the actuating plunger and an actuating surface of a machining element, which is activated in the selected rotational position and is preferably the moving machining element of the pair of machining elements. When the turret is in a first rotational position, the first pair of machining elements makes contact with the actuating surface of the actuating plunger.When the turret rotates into its second position, the working surface of the first pair of workpieces moves away from the actuating surface of the plunger, and a corresponding actuating surface of a second pair of workpieces is brought into contact with the actuating surface of the plunger. The actuating surfaces can be loosely in contact with each other, which enables the turret to rotate. In this case, a spring preload can provide a basic contact force between the actuating surfaces without the tool actuating unit generating an actuating force. Alternatively, the actuating surfaces can be separated by a gap without the tool actuating unit applying any actuating force.

[0031] There are many possibilities for the basic design of the tool actuation unit, whereby all different types of tool actuation units known from the prior art can be used within the scope of the invention.

[0032] For one proposal of the invention, the tool actuation unit is a crimping machine actuation unit, so that the inventive rotation of at least one pair of the machining bodies can be used for a stationary crimping machine.

[0033] In another aspect of the invention, the tool actuation unit is a hand-operated pliers actuation unit, which in particular has hand levers by means of which manual actuation of the tool is possible. For example, the tool is then a crimping pliers which, depending on the design of the working body, can crimp different workpieces in different rotational positions and / or perform further processing operations, in particular cutting and / or cutting for stripping.

[0034] For the design of the tool actuation unit as a hand-operated pliers actuation unit, the following possibilities are preferably available within the scope of the invention:

[0035] In a first embodiment, the hand-operated pliers actuation unit has a base body that integrally forms the hand levers and the actuating plunger. Conventional hand-operated pliers actuation units require several components (especially rods or levers) to be connected by pivot bearings to form a transmission mechanism, thus creating the actuating stroke and converting this movement into a movement of the actuating plunger. This is disadvantageous in terms of size, manufacturing complexity, component diversity, and assembly. In the inventive, integral design of the base body ensures the relative movement of at least one hand lever with respect to the actuating plunger over the working stroke by an inherent elasticity of the base body and thus a deformation of the base body.While the aforementioned prior art hand-operated pliers actuating units utilize pivot bearings to achieve the stiffest possible design of the components, this proposed invention allows for the targeted use of elastic components, specifically an elastic base body, thus enabling the use of elastic materials. For example, the base body can be manufactured from a plastic, particularly using injection molding or additive manufacturing processes, and the plastic can also be fiber-reinforced. Other materials that can be used within the scope of the invention include biogenic materials, tools made from renewable resources, compostable materials, and / or recyclable materials. To provide just one example that does not limit the invention, such a hand-operated pliers actuating unit can be designed as depicted and described in DE 20 2023 000 293 U1.Preferably, the hand-operated pliers unit does not have a swivel bearing.

[0036] In a second embodiment, the hand-operated pliers unit comprises a fixed tool part with a fixed jaw and a fixed hand lever. Furthermore, the hand-operated pliers unit includes a movable hand lever. The hand-operated pliers unit also includes a movable jaw and a pressure lever. In this case, the movable jaw is articulated to the fixed tool part via a pivot bearing. The movable hand lever is articulated to the movable jaw via a pivot bearing. The pressure lever is articulated (at one end) to the fixed tool part via a pivot bearing and (at the other end) to the movable hand lever via a pivot bearing. A toggle lever mechanism is formed in the hand-operated pliers unit by the pressure lever forming a first toggle lever, and a section of the movable hand lever forming a second toggle lever.The pivot bearing, with which the pressure lever is articulated to the movable hand lever, forms the toggle joint in the toggle lever mechanism. In this configuration, one tool jaw (in particular the movable tool jaw [or the fixed tool jaw]) serves as the receptacle for the tool insert. The other tool jaw (the fixed tool jaw [or the movable tool jaw]) then has the actuating plunger or supports it. Thus, the measures according to the invention, while ensuring the rotational freedom of the machining elements, can be integrated into fundamentally known hand-operated pliers or crimping pliers that have a toggle lever mechanism as previously described. For example, integration into a crimping or pressing pliers as described in DE 198 022 87 C1 is possible.

[0037] In a third embodiment, the hand-operated pliers actuation unit has a fixed tool part comprising a C-shaped tool head and a fixed hand lever. In this case, the C-shaped tool head forms the fixed tool jaw. The hand-operated pliers actuation unit also has a slide that is translationally displaceable along the tool head and forms a movable tool jaw. The hand-operated pliers actuation unit also includes a pressure lever and a movable hand lever. In the hand-operated pliers actuation unit, the pressure lever is pivotally connected to the fixed tool part at one end and to the movable hand lever at the other end via a pivot bearing. The movable hand lever is pivotally connected to the slide via a pivot bearing.A toggle lever mechanism is formed by the pressure lever forming a first toggle lever, while a section of the movable hand lever forms a second toggle lever. The toggle joint of the toggle lever mechanism is then formed by the pivot bearing with which the pressure lever is articulated to the movable hand lever. One tool jaw (the movable tool jaw [or the fixed tool jaw]) forms the receptacle for or supports the tool insert, while the other tool jaw (the fixed tool jaw [or the movable tool jaw]) has or supports the actuating plunger. This allows, for example, the integration of the measures according to the invention into a crimping tool with a drive mechanism, as is fundamentally illustrated and described in DE 198 077 37 C2.

[0038] In a fourth embodiment, the hand-operated pliers actuation unit can have an O-shaped tool head that forms a fixed tool jaw. A slide is guided on the tool head so as to be translationally displaceable. The slide forms a movable tool jaw. Two movable hand levers are articulated to each other via a pivot bearing (similar to scissors). In this fourth embodiment, the hand-operated pliers actuation unit has two pull tabs. Each pull tab is articulated at one end to an associated hand lever via a pivot bearing, while at the other end it is articulated to the tool head via a pivot bearing. A pivot pin of the pivot bearing, through which the two hand levers are articulated to each other, is then arranged in a receptacle of the slide.The actuating force generated by the hand levers can then be transmitted to the slide via the contact of the pivot pin with the slide's receptacle. For this fourth embodiment, for example, the measures according to the invention can be integrated into a type of crimping tool as described in German publications DE 100 569 00 C1 and EP 0 468 335 A2.

[0039] As mentioned previously, a fixed or interchangeable connection can be made between the tool insert and a receptacle for the tool actuation unit. For an interchangeable mounting of the tool insert to the receptacle for the tool actuation unit, connection methods known from the prior art can generally be used. In one embodiment of the invention, a tool jaw has a recess open at the edge. The tool insert then has a cross member. To support the tool insert interchangeably on the tool jaw, the cross member is arranged in the recess. Disassembly is then possible by simply removing the tool insert and thus the cross member from the recess.It is quite possible that additional coupling or connection measures are used between the tool insert and the mounting of the tool actuation unit, in particular an additional fastening screw and / or further support of a second cross member in a second open-edged recess. The interaction of the (at least one) cross member with the (at least one) recess serves to transmit a force and to provide support and / or to prevent displacement and / or rotation. A corresponding support between at least one cross member and at least one open-edged recess can also be used to support an actuating plunger or a housing of the tool insert on a tool jaw.

[0040] In the embodiments described above, the tool jaw can have two parallel and spaced-apart tool jaw plates, which have an open-edged recess, or preferably two spaced-apart open-edged recesses, on the side facing the tool or gripper jaw. In this case, the tool insert, actuating plunger, or the housing of the tool insert can have a flange that is arranged in the space between the tool jaw plates and is thus guided and supported between the tool jaw plates. The tool insert, the actuating plunger, or the housing of the tool insert can then have one or two cross members, which provide additional support and securing against displacement or rotation.Preferably, the interchangeable connection of the tool insert, the actuating plunger or the housing of the tool insert is then carried out by means of the cross bolts and recesses as described in DE 198 022 87 C1 (albeit for supporting conventional die halves on tool jaws).

[0041] Another solution to the problem underlying the invention is a tool insert which is particularly intended for single or interchangeable insertion into a receptacle of a tool confirmation unit in order to form a tool, as has been explained above.

[0042] The tool insert according to the invention comprises a turret. The turret has a guide that enables rotational movement of the turret about an axis of rotation within the tool. This guide can be, for example, a cylindrical outer or inner guide surface that slides around the axis of rotation in a corresponding inner or outer guide surface of the tool actuation unit. Alternatively, the guide can be formed by a (one- or multi-part) housing of the tool insert, which rotatably mounts the turret in a rotary bearing. The turret used in the tool insert according to the invention has at least two pairs of machining elements. The machining axes of the pairs of machining elements are oriented radially to the axis of rotation in different directions.In this way, it is ensured that by rotating the turret around the axis of rotation in different rotational positions, different specific pairs of machining elements are activated for pressing a workpiece.

[0043] Another solution to the problem underlying the invention is a group of tools designed as described above. This group of tools comprises two subgroups: a first subgroup and a second subgroup. The tools of the first subgroup and the tools of the second subgroup then have different types of tool actuation units. For example, tools of the first subgroup can have tool actuation units designed as crimping machine actuation units, while the tools of the second subgroup can have tool actuation units designed as hand pliers actuation units. It is also possible for the tools of the different subgroups to each have different types of hand pliers actuation units.The tools from different subgroups can then be used for different applications. According to the invention, the tools of the two subgroups have identical tool inserts despite the different designs of the tool actuation units. In this way, the variety of components can be reduced, which is advantageous with regard to manufacturing, storage, and provisioning costs.

[0050] In the following figure description, some components and features that are identical or similar in design and / or function are marked with the same reference symbols. In this case, the additional letter a, b, etc., may be added for differentiation. References to these components and features can then be made with or without the additional letter, in which case they may refer to one component or feature, several components or features, or all components or features.

[0051] Fig. 1Figure 1 shows a tool 1 with a base body 2. The base body 2 forms a receptacle 3 for a tool insert 4.

[0052] The base body 2 forms a tool head 5, which has a receptacle 3. Hand levers 6 and 7 extend from the tool head 5, which are used for the Fig. 1In the illustrated embodiment, the levers 6, 7 are oriented approximately parallel to each other, although this is not strictly necessary. In the end region facing away from the tool head 5, pressure bars 8, 9 are integrally formed on the hand levers 6, 7. These pressure bars extend back towards the tool head 5 at an acute angle to the corresponding hand levers 6, 7. The two pressure bars 8, 9 converge towards the tool head 5 in a V-shape and are rigidly connected to each other at the junction of the legs of the V, i.e., at the end regions closest to the tool head 5. The junction of the pressure bars 8, 9 forms an actuating plunger 10. The actuating plunger 10 has an actuating surface 11 on the side facing the tool head 5 and thus the tool insert 4.

[0053] The tool 1 has a cover 12 which is screwed to the base body 2 in the area of ​​the tool head 5 by means of fastening screws 35. The receptacle 3 forms an interior space between the base body 2 and the cover 12.

[0054] Tool insert 4 is for disassembled cover 12 in Fig. 2The tool insert 4 has a turret housing 13, which is arranged in the interior space bounded by the receptacle 3 and the cover. The turret housing 13 has a cylindrical outer surface 14, which forms a guide 15. The turret housing 13 is rotatably guided on a corresponding cylindrical inner surface of the tool head 5, which is formed by the receptacle 3, such that the turret housing 13 is rotatably guided about an axis of rotation 16 relative to the tool head 5. Alternatively or cumulatively, the turret housing 13 can have a bore 17, which forms a guide 15. The guide 15 can then ensure rotation of the turret housing 13 and thus of the tool insert 4 about the axis of rotation 16 by guiding a pin 18 formed by the cover 12 in the guide 15 (see Figure 1). Fig. 4 ).

[0055] The tool insert 4 has three pairs of machining bodies 19a, 20a; 19b, 20b and 19c, 20c in the illustrated embodiment.

[0056] In the illustrated embodiment, the machining bodies 19 are designed as movable machining bodies over the machining stroke, while the machining bodies 20 are designed as fixed machining bodies over the machining stroke. The movable machining body 19 is displaceable relative to the fixed machining body 20 along a machining axis 21. The machining bodies 19 and 20 are distributed circumferentially around the axis of rotation 16 such that they are arranged in a 2 o'clock position, a 6 o'clock position, and a 10 o'clock position. The machining axes 21a, 21b, and 21c are oriented radially to the axis of rotation 16 and have orientations offset by 120° in the circumferential direction. The displacement of the movable machining bodies 19 is effected by at least one spring 22 or 23.

[0057] The fixed machining body 20 is fixedly mounted to the turret housing 13 or formed directly from it. The movable machining body 19 is guided in the direction of the machining axis 21 by a guide provided by the turret housing 13. In the illustrated embodiment, the guides for the movable machining bodies 19 are formed by ribs of the turret housing 13.

[0058] On the side facing away from the fixed machining body 20, the movable machining bodies 19 have a projection 24 that forms an actuating surface 25, which is intended for interaction with the actuating surface 11 of the actuating plunger 10. For this purpose, the turret housing 13 has an opening 26 in the guide 15 through which the actuating plunger 10 and / or the projection 24 extend. The turret housing 13 has blind bores 27 distributed parallel to the axis of rotation 16 and circumferentially around the axis of rotation, and arranged radially inside the machining bodies 20.

[0059] As especially in Fig. 3As can be seen, detent springs 28 are inserted into the blind bores 27, so that they are supported at one spring base point on the bottom of the blind bore 27. The other spring base point of the detent springs 28 actuates detent elements 29, which here are designed as detent balls 30. The detent elements 29 engage in detent recesses 31 of the cover 12, which can be blind bores, in a first, second, and third rotational position of the turret housing 13. In the first rotational position, which is in Fig. 5As shown, the pair of machining bodies 19a, 20a with the machining axis 21a is aligned such that the extension 24a of the machining body 19a can interact with the actuating plunger 10 of the base body 2. In the second rotational position, the pair of machining bodies 19b, 20b can then be brought into interaction with the actuating plunger 10, while correspondingly in the third rotational position, the pair of machining bodies 19c, 20c can be brought into interaction with the actuating plunger 10.

[0060] In the illustrated embodiment, the turret housing 13 is roughly mushroom-shaped, with a mushroom head forming the cylindrical surface 14 with the guide 15, and the machining elements 19, 20 with the springs 22, 23 and the extension 24 arranged inside the mushroom head. The mushroom stem of the turret housing 13 forms an actuating extension 32, which is essentially cylindrical. The actuating extension 32 extends from the receptacle 13 and the base body 2 on the side facing away from the cover 12. The actuating extension 32 has knurling 33. The user can rotate the actuating extension 32 in the area of ​​the knurling 33 using their fingers, thereby changing the rotational positions. The user receives haptic feedback when the detent elements 29 engage in the detent recesses 31.The mushroom head of the turret housing 13 is axially trapped on one side between the cover 12 and on the other side a base 34 formed by the base body 2.

[0061] In Fig. 5 It can be seen that the pairs of machining bodies 19, 20 are designed for different types of machining. In the first pair, the machining bodies 19a, 20a are designed as die halves 36, 37, which can be used to crimp a connector to a cable. The machining bodies 19b, 20b of a second pair each have cutting edges 38, 39 with straight cutting edges, which can be used to cut through a workpiece or cable. The machining bodies 19c, 20c of a third pair each have a cutting edge 40, 41, whose cutting edges are approximately semicircular and which serve to cut into the insulation sheath of a cable for stripping.

[0062] Operation of tool 1 according to Figs. 1 to 5The process proceeds as follows: First, a pair of machining bodies 19a, 20a are located in the area of ​​the opening 26, whereby the machining axis 21a of these machining bodies 19a, 20a is oriented coaxially to the actuating axis of the actuating plunger 10. Initially, the actuating surface 11 of the actuating plunger 10 forms a gap 42 with the actuating surface 25a of the extension 24a of the machining body 19a. If the user then applies hand forces to the hand levers 6, 7 such that an elastic deformation of the base body 2 occurs, causing the end regions of the hand levers 6, 7 facing away from the tool head 5 to move towards each other, this results in a movement of the actuating plunger 10 in the direction of the machining axis 21a. As a result of this movement, the gap 42 is closed and the actuating plunger 10 comes into contact with the actuating surface 11 against the actuating surface 25a of the extension 24a of the machining body 19a.A further increase in the force applied by hand to the hand levers 6, 7 results in an actuating force being applied from the actuating plunger 10 via the actuating surfaces 11, 25a to the machining body 19a. This actuating force, in turn, causes the machining body 19a to move towards the machining body 20a, thus machining the workpiece. Once machining is complete, the forces exerted by hand on the hand levers 6, 7 are released. As a result of the action of the springs 22a, 23a, the machining bodies 19a, 20a are moved apart again, and the actuating plunger 10 is moved away from the tool head 5 in the direction of the machining axis 31, thus restoring the gap 42. Further workpieces can then be successively machined in a corresponding manner using the machining bodies 19a, 20a.

[0063] If, however, it is necessary to cut through a workpiece, the tool insert 4 is rotated such that the extension 24b of the machining body 19b is arranged in the effective area of ​​the actuating plunger 10, which in the illustrated embodiment is achieved by means of a rotation in Fig. 5 This can be achieved by rotating the hand levers 6 and 7 by 120° counterclockwise. If the hand levers 6 and 7 are now manually actuated, a workpiece can be cut between the cutting edges 38 and 39 of the machining bodies 19b and 20b.

[0064] If a cable is to be stripped, the turret housing 13 is rotated again such that the extension 24c of the processing body 19c is arranged in the effective area of ​​the actuating plunger 10, which is achieved by a rotation of 240° counterclockwise from the Fig. 5The rotational position shown can be achieved. The cutting stroke for cutting the cutting edges 40, 41 into the insulation sheath of the cable can then also be brought about by actuating the hand levers 6, 7 and transmitting an actuating force thus generated from the actuating plunger 10 via the actuating surfaces 11, 25c to the processing body 19c.

[0065] It is possible, for example, that in the different rotational positions of the tool insert 4, the machining bodies 19b, 20b in Fig. 5 First, the cable is cut to the desired length, then an end area of ​​the conductor is stripped using the processing bodies 19c, 20c, and finally the cable is crimped with the stripped end area to a connector using the processing bodies 19a, 20a.

[0066] Figs. 6 to 9Figure 1 shows another embodiment of a tool 1. The tool 1 has a fixed tool part 43, which forms a fixed hand lever 44 and a fixed tool jaw 45. The tool 1 further has a movable hand lever 46, a pressure lever 47 and a movable tool jaw 48.

[0067] The pressure lever 47 is pivotally connected at one end to the fixed tool part 43 via a pivot bearing 49. At the other end, the pressure lever 47 is pivotally connected via a pivot bearing 50 to the movable hand lever 46. The fixed tool part 43 is pivotally connected at the fixed tool jaw 45 via a pivot bearing 51 to the movable tool jaw 48. The movable hand lever 46 is pivotally connected to the movable tool jaw 48 via a pivot bearing 52. The tool 1 has a toggle lever drive 53. In the toggle lever drive 53, the pivot bearing 50 forms the toggle joint 54. A first toggle lever 55 is formed by the pressure lever 47 between the pivot bearings 49 and 50. A second toggle lever 56 is formed by the movable hand lever 46 between the pivot bearings 50 and 52. A crimping tool with such a drive kinematics and a toggle lever drive 53 is fundamentally known from DE 198 02 287 C1.

[0068] The fixed tool jaw 45 forms a receptacle 3 for a tool insert 4. The fixed tool part 43 is formed by two parallel and spaced-apart tool part plates 57, 58. The movable tool jaw 48, the movable hand lever 46, and the pressure lever 47 are arranged and guided between the tool part plates 57, 58. The tool part plates 57, 58 each have a bearing eye 59, 60 to form the receptacle 3.

[0069] Until further notice, tool insert 4 is designed as required for the Figs. 1 to 5As previously explained, here the cover 12 is not attached to the fixed tool jaw 45, but to the turret housing 13, so that the cover 12 is rotated with the turret housing 13 about the axis of rotation 16 between the rotational positions. The cover 12 has three groove-shaped continuous recesses 61a, 61b, 61c extending radially inwards from the cylindrical surface, which, when the cover 12 is mounted on the turret housing 13, are aligned with an associated pair of machining elements 19, 20, so that the receptacle 62 formed by the pair of machining elements 19, 20, into which the workpiece can be inserted, is accessible.

[0070] The cylindrical segment-shaped outer surface of the cover 12 forms a guide 15 for the rotation of the tool insert 4 about the axis of rotation 16. The cylindrical segment-shaped partial outer surfaces of the cover 12 forming the guide 15 fit precisely into the bearing eye 59. Similarly, the turret housing 13 can be guided in the bearing eye 60 by means of a shoulder or a guide surface.

[0071] The tool insert 4 is secured axially between the tool part plates 57, 58 by the turret housing 13 being axially trapped between the limits of the bearing eyes 59, 60.

[0072] In the illustrated embodiment, the cylindrical surface of the fixed tool jaw 45 is formed on the one hand by the cylindrical surface of the tool part plates 57, 58 in the area of ​​the bearing eyes 59, 60 and between these by the cylindrical surface of the turret housing 13.

[0073] For the exemplary embodiment according to Figs. 6 to 9The actuating plunger 10 is not an integral part of the movable tool jaw 48, but is designed separately, detachably, and replaceably from the movable hand lever 46. An actuating plunger insert 63 forms the actuating plunger 10 and a flange 46, which forms a base of the actuating plunger 10, as a single unit. Two pin-like cross members 65a, 65b, oriented parallel to each other, extend from the flange 46 on both sides. While it is possible in principle for the cross members 65 to be formed integrally with the actuating plunger insert 63, they are preferably bolts that are inserted or pressed into bores in the flange 24. Furthermore, the flange 46 has a bore 66.

[0074] The movable tool jaw 48 has, on the upper side of the two parallel tool jaw plates 67a, 67b facing the fixed tool jaw 45, open-edged recesses 68a, 68b, the distance between which corresponds to the distance between the crossbeams 65a, 65b.

[0075] For mounting the actuating plunger insert 63 on the movable tool jaw 48, the flange 64 is guided between the tool jaw plates 67a, 67b. The crossbeams 65 come into contact with the recesses 68 of the tool jaw plates 67, thus supporting the actuating plunger insert 63 with the actuating force via the crossbeams 65 against the recesses 68 of the tool jaw plates 67. The support of the crossbeams 65 in the recesses 68 also ensures the desired orientation of the actuating plunger insert 63 and thus of the actuating plunger 10. The actuating plunger insert 63 can be further secured to the movable tool jaw 48 by screwing the movable tool jaw 48 to the actuating plunger insert 63 by means of a fastening screw 69 that extends through the bore 66 of the flange 64.Preferably, the bore 66 has an interference fit with respect to the fastening screw 69, so that the position of the actuating plunger insert 63 relative to the movable tool jaw 48 is not determined by the fastening screw 69, but by the cross members 65.

[0076] During operation of the tool 1, the actuating plunger 10 extends between the limits of the bearing eyes 59, 60 through the opening 26 of the turret housing 13 into the interior of the tool insert 4, where the actuating plunger 10 then interacts with the corresponding actuating surface 25 of the respective machining body 20 in the manner described. The support of the actuating plunger insert 63 via crossbeams 65 on recesses 68 of a tool jaw 48 corresponds in principle to the connection as described in DE 198 02 287 C1. For further details, please refer to that publication.

[0077] In Figs. 10 to 13Another type of tool 1, configured as crimping pliers 111, is shown: In this case, the fixed tool part 43, together with the fixed tool jaw 45 and the fixed hand lever 44, forms a C-shaped tool head 70. For this embodiment, a slide 71 is translationally guided on the fixed tool part 43. The slide 71 forms the movable tool jaw 48. In this case, the movable hand lever 43 is articulated to the slide 71 at the end region facing the tool head 70 by means of a pivot bearing 72, wherein a pivot pin 73 of the pivot bearing 72 may be guided in an elongated hole 74 of the fixed tool part 43 to ensure the translational degree of freedom. A pressure lever 74 is articulated to the fixed tool part 43 in a pivot bearing 75 and to the movable hand lever 46 in a pivot bearing 76.In the same manner as described for the preceding embodiment, a toggle lever drive 54 is formed in this way.

[0078] Regarding further information on the basic structure of a tool 1 of this type, reference is made by way of example to EP 2 096 725 B1 or crimping pliers which are distributed by the applicant under the designation "CS30".

[0079] In this embodiment as well, the fixed tool part 43 has two tool part plates 57, 58 and bearing eyes 59, 60 in which the tool insert 4 is arranged. Reference is made in this regard to the description of the embodiment, which is set out in Figs. 6 to 9 was described.

[0080] Here too, the tool 1 has a replaceable actuating plunger insert 63, which is designed as previously described. The crossbeams 65 of the actuating plunger insert 63 are supported here by recesses 68 formed by the two slide plates 76a, 76b of the slide 71.

[0081] In Figs. 14 to 16 Figure 1 shows a tool 1 designed as a crimping tool 111, in which the basic structure of the drive mechanism corresponds to the embodiment shown in Figure 1. Figs. 6 to 9As shown, the tool 1 has both a tool insert 4, which is interchangeably mounted on the fixed tool jaw 45, and an actuating plunger insert 63, which is interchangeably attached to the movable tool jaw 48. Both the movable tool jaw 48 and the fixed tool jaw 45 have parallel plates with recesses 68a, 68b. Accordingly, both the actuating plunger insert 63 and the tool insert 4 have cross members 65, a bore 66, and a flange 64.

[0082] Thus, the tool insert 4 with its flange 64 can be inserted between the tool part plates 57, 58, and the tool insert 4 can be supported by the cross members 65 in the recesses 68 of the tool part plates 57, 58. Additional securing is then provided by means of the fastening screw 69, which extends through the bore 66 of the tool insert 4.

[0083] The actuating plunger insert 63 is supported on the movable tool jaw 48 by the flange 64 being positioned between the plates of the movable tool jaw 48. The cross members 65 of the actuating plunger insert 63 are supported in the recesses 68 of the plates. Additional securing is provided by a fastening screw 69, which extends through the bore 66 of the actuating plunger insert 63.

[0084] In Figs. 17 to 20The tool insert 4 and the actuating plunger insert 63 are shown as individual components. In this embodiment, the tool insert 4 is not directly inserted into a receptacle 3 formed by the fixed tool jaw 45. Instead, the tool insert 4 has a housing 78 in which the turret housing 13 is rotatably mounted. The housing 78 has the cross members 65, the flange 64, and the bore 66, which enables the previously described support via the cross members 65 in recesses 68 of the fixed tool jaw 45. The cover 12 of the tool insert 4 is then screwed to the housing 78. The above applies to the basic design of the tool insert 4 and the actuating plunger insert 63 and their assembly on the tool jaws 45, 48.The cover 12 is arranged in a correspondingly shaped recess of the housing 78, so that the outer surface of the cover 12 is flush with the flange 64, in order to allow the housing 78 to be inserted between the tool part plates 57, 58 up to the area of ​​the cover 12.

[0085] Fig. 21 shows an embodiment of a tool 1 designed as crimping pliers 111, which has a C-shaped tool head 70 and is basically designed according to the embodiment in Figs. 10 to 13is designed. However, here the tool insert 4 is not mounted in bearing eyes 59, 60 of the fixed tool jaw 45. Rather, for this embodiment, the fixed tool jaw 45 has recesses 68 in the area of ​​the tool part plates 57, 58. The cross members 65 of the housing 78 of the tool insert 4 can then be supported in the recesses 68. For this embodiment, both an interchangeable actuating plunger insert 63 and an interchangeable tool insert 4 with support via cross members 65 are used. It is possible that the actuating plunger insert 63 and the tool insert 4 are identical in design to the tool insert 4 and the actuating plunger insert 63 that was used for the tool 1, which is in the Figs. 14 to 20 has been described so that these are multifunctional and can be used for different types of tools 1.

[0086] Fig. 22Figure 1 shows another embodiment of the tool 1 in the form of crimping pliers 111. In this case, the tool 1 has an O-shaped tool head 79, which is formed by two parallel, spaced-apart tool head plates. The tool 1 has two movable hand levers 80, 81. The hand levers 80, 81 are directly connected to each other at their end regions facing the tool head 79 via a pivot bearing 82. Furthermore, the hand levers 80, 81 are equipped with... Fig. 22The pull tabs 83, 84 (not shown) are articulated to the tool head 79 via pivot bearings 85, 86. A slide 87 is guided translationally on the tool head 79. In the illustrated embodiment, the slide 87 directly forms the actuating plunger 10. The slide 87 has a receptacle 88 on the side facing the hand levers 80, 81, in which a pivot pin 89 of the pivot bearing 82 is supported. When the hand levers 80, 81 are pulled in the closing direction, the pivot pin 89 transmits an actuating force via the receptacle 88 to the slide 87 and thus to the actuating plunger 10.

[0087] Regarding the basic structure of the in Fig. 22 and 23 For the tool shown in 1, reference is made by way of example to the publications DE 100 56 900 C1 and EP 0 468 335 A2.

[0088] In this embodiment, the tool insert 4 is inserted directly into the tool head 79, which is held between the two plates of the tool head 79. The rotary movement of the tool insert 4 can be guided via the cylindrical surface of the turret housing 13 and / or the cylindrical surface of the cover 12 in an inner surface of a bearing eye of the tool head 79. It is possible that a [missing information - likely a specific component] is attached to the tool head 79. Fig. 22 and 23 an additional cover (not shown) is attached, which covers the tool insert 4 to the outside (except for access to the actuating plunger 10 and to the pair of the respective activated machining bodies 19, 20).

[0089] Fig. 24Figure 1 shows an embodiment in which the tool 1 is designed 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 Figure 1). Fig. 25 , 26 The guide elements 92, 93 are guided relative to each other by guide pins 94, 95, so that the guide elements 92, 93 can only perform a translational movement in the direction of an actuating axis 96. It is possible that a displacement sensor and / or a sensor for sensing the actuating force is integrated into the crimping machine 90, the tool jaws 45, 48, or the guide elements 92, 93. Further information on this can be found in publication EP 2 698 885 B1.

[0090] The actuating plunger insert 63 is mounted directly to the guide part 93. The tool insert 4 has a housing 78 which is mounted to the guide part 92.

[0091] The guide parts 92, 93 have T-shaped elongated extensions in the fastening area on the tool jaws 45, 48, by means of which the guide parts 92, 93 can be inserted into correspondingly shaped T-slots of the tool jaws 45, 48.

[0092] The actuating plunger insert 63 and the housing 78 of the tool insert 4 have rib-shaped, elongated projections 97, 98 on their lateral side surfaces, which can be inserted vertically into corresponding vertically oriented grooves in the guide parts 92, 93 (not shown in the figures). Additionally, the tool insert 4 can be fastened to the guide part 93, and the housing 78 can be fastened to the guide part 92, by means of additional connections, in particular screws.

[0093] It is possible that (as shown in the figures) the actuating extension 32 has longitudinal grooves 99 which extend parallel to the axis of rotation 16 and coaxial to the pairs of machining bodies 19, 20 and through which the receptacles 62 formed by the machining bodies 19, 20 are accessible.

[0094] Furthermore, the tool may be equipped with a positive locking mechanism 100. A positive locking mechanism 100 serves to secure the position of the hand levers 44, 46 and the tool jaws 45, 48 reached after a partial machining stroke against an undesired opening movement during the machining stroke, even if an actuating force, in particular the hand force applied by the user to the hand levers 44, 46, is temporarily removed. A positive locking mechanism 100 ensures that the hand levers 44, 46 and the tool jaws 45, 48 can only open once the machining stroke has been completed. An exemplary embodiment of a positive locking mechanism 100 is described using the following: Fig. 9The pressure lever 47 has a toothed section 101. A pawl 102, which is pivotally mounted on the movable hand lever 46 and actuated by a spring 103, engages the toothed section 101. With the closing movement of the movable hand lever 46, the pawl 102 slides along the toothed section 101 in a ratchet-like manner, while the pawl 102 blocks any opening movement. Once the machining stroke is complete, the pawl 102 pivots so that a different side of the pawl's locking tooth engages with the toothed section 101, allowing the pawl 102 to slide along the toothed section 101 in a ratchet-like manner for the opening movement.
