Description

Extruder

The invention relates to an extruder.

A known extruder of this type is referred to European patent EP 0 379 937 A2, for example, which is used to push a metal blank through a die. For this purpose, an extruder usually includes a die, a blank container, and an extrusion punch. The blank container surrounds and supports the blank during extrusion, so that the blank can only flow out through the die. The extrusion punch can be removed relative to the blank container and the die. Through the extrusion punch, the extrusion force is usually introduced into the extruder through a main cylinder. Preferably, the extruder is composed of a piston Imposed by a cylinder. A frame system is generally used as a pressure frame. This frame has at least one cylindrical beam and a pair of upright beams, which are connected to each other through a pre-compressed tie rod; wherein a mold is installed on the cylindrical beam of the main cylinder and the opposite On the beam. The pull rod usually includes an effective tension element between the cylindrical beam and the opposite beam and an effective pressure member between the cylindrical beam and the opposite beam.

In this situation, there should be a difference between direct and indirect extruders, and direct extruders are used to extrude the extrusion punches longer, face the mold and pass through the blank container during extrusion; and indirect The extruder sets the mold on the die punch during extrusion and during special processes such as static extrusion, and the die punch passes through the blank container. Exemplary extruder embodiments where continuous extruders are less common show an elongated extrusion punch and a die punch. Clearly, especially in In the case of a continuous extruder, the die itself is movable relative to the frame during extrusion. When necessary, the movement of the extrusion punch can be eliminated, for example, when all movements are reversed; similarly, both the extrusion punch and the die can be moved in an axial direction. The same applies to the blank container, especially for the purpose of loading, the blank container is designed to be axially movable relative to the die and / or extrusion punch, and suitably, it can also follow an extrusion Movement, this squeeze movement moves axially relative to the frame.

Therefore, during extrusion, components that are subjected to the load caused by the force and moment caused by the extrusion, such as blank containers, molds or extrusion punches, especially other components may have to be relative to When the frame or other components are moved, they are movably guided by a guide unit. This does not necessarily have to be the case, but it can occur indirectly via the corresponding components, which in turn support these components. Therefore, a container rack is usually installed, which supports the blank container and is guided on the frame. Similarly, the extrusion punch is usually provided on a container rack, which is in turn guided on the frame. It is also possible to provide corresponding mounts or beams in the case of molds or other components and then guide them accordingly.

The guide unit usually includes a guide device, wherein two guide devices are usually installed on both sides of the corresponding component, or three or more guide devices can be installed, which can be plural A guiding device, so that the corresponding torque system can also be resisted in an appropriate way. Such a guide device usually includes a guide element on one side of a component, which is installed on the corresponding component via a guide component carrier provided on the corresponding component; wherein, the The guide element carrier can also be guided integrally with the component. To supplement this, the guiding device will also have a guiding element on the side of the frame, which is guided in a guiding manner on the side of the assembly The upper guide elements interact and are fixed to the frame. In particular, the slider, the sliding pad, and the corresponding bearing are used as a guide element on one side of the module; wherein, the corresponding guide rail is usually used as a guide on one side of the frame. element. Clearly, this specific embodiment can also be configured in the opposite way if necessary.

Furthermore, such a component that is subject to a load during the squeeze introduced by the force and moment caused by the squeeze is usually electrically driven by an electric drive, wherein, depending on the specific embodiment, it is used Either an electric motor or a hydraulic drive. Under this condition, the electric driver is engaged with a driving position on one side of the component, and the driving position is provided on a driving position carrier on the corresponding component, where the driving position is supported if necessary. The fixture can be integrally formed with the cross beam or container rack, or integrally formed with the component to be driven. In particular, for example, an electric drive gear and a rack system that mesh with each other can be used for electric drive. Clearly, multiple drive gear trains can also mesh with the components, which can be moved from different sides, especially in order to avoid excessive tilting moments, which exist during the drive through the electric drive.

The problem proposed by the present invention is to minimize the influence of the moment and the force on the rest of the extruder, which is caused by the squeeze.

The problem raised by the present invention is solved by having the technical features requested by the independent patent application scope. A further effective embodiment may also be its independent patent application scope, which can be found in the attached patent application scope and the following description.

Under this condition, the present invention is based on the basic knowledge that the influence of the torque and force caused by extrusion on the rest of the extruder can be minimized, which can be prevented, whether it can be It can happen through the interaction between the load components themselves, which may occur, in particular, the corresponding fixed components such as the frame may allow a specific gap, but it is possible to maintain the most accurate guidance.

When used in an extruder for a blank extrusion, the specific realization of this basic concept is to allow the impact of the torque and force caused by the extrusion on the rest of the extruder to be minimized, while the blank extrusion The pressing system uses a mold of an embryo container and an extrusion ram. The extrusion punch is movable relative to the container and the mold; during the extrusion, the extrusion is carried by the extrusion station. At least one component of the extruder caused by the applied force and moment is guided movably along a guide unit that includes at least one guide device, each of which A guide element is included on one side of the module, and each guide element on the side of the module is disposed on a guide element carrier on the corresponding module; the guide element carrier is characterized in that: It is connected to the corresponding component separately.

If it is used to push a blank through a die with a blank container and an extrusion punch, the impact of the torque and force caused by the extrusion on the rest of the extruder is also minimized, and The extrusion punch is movable relative to the blank container and the die; wherein, at least one component of the extruder that is loaded by the force and moment caused by the extrusion during extrusion is passed through an electric drive. Electric drive; wherein, the electric drive is engaged with a driving position on one side of the module, and the driving position on the side of the module is provided on a driving position carrier on the corresponding module; The driving position carriers are respectively connected to corresponding components.

The extruder can be a direct or indirect extruder, because for this type of extruder, a relatively large pressure is applied to a specific component of the direct or indirect extruder. in In the case of a hydrostatic press, there is a relatively large pressure on the components, so that the solution described in this case can be used. It is the same, the solution described in this case is also beneficial to use in punching machines or other presses.

Clearly, where appropriate, a plurality of guides or electric drives can also be provided on either side of the load assembly, so that a plurality of guides or electric drives can be installed accordingly, and each of them A guide element on one side of the component or a drive position on the side of the component is shown, each of which is connected to a guide element carrier or a drive position carrier on the corresponding component.

As mentioned above, a container rack supporting the blank container or a cross beam supporting the extrusion punch can be used as a load component. On the other hand, it is clear that the blank container or extrusion punch system can immediately constitute the load assembly. Clearly, if appropriate, a component which is subjected to a load caused by the forces and moments caused by the extrusion during the extrusion and is movably guided along a guide unit is electrically driven by an electric motor, which The system also shows that a guide element carrier or a drive position carrier is connected as a load assembly, respectively. In particular, a possible embodiment in this case is a die or a corresponding die punch or a corresponding support beam or carrier. It is also conceivable that it can be a valve body, a seal, or a pipeline, which affects the extrusion material and is similarly subjected to a load caused by the force and moment caused by the extrusion during the extrusion, and is therefore Configure accordingly.

As mentioned above, sliders, slide pads, or slide rails, and any kind of roller bearing, are likely to be used as guide elements on one side of the assembly. Therefore, the matching guide element on the frame side may be a guide rail or the like, wherein, in this case, the guide element on the component side and the guide element on the frame side may be reversed and interchanged. Instead. Herein, the guide element can be defined as a component of a guide unit or a guide device, which is a movable The methods directly contact each other and receive the guiding force.

It is also applicable to the driving position on one side of the component or the driving position on the side of the frame. It means that the two components of the driver are movable to each other and transmitting force, and the driving position on the component side For example, as a rack or piston, it moves with the moving and load components, and the driving position on one side of the frame is fixedly maintained on the corresponding frame and can be formed as a rack or cylinder. Obviously, the driving position on the module side and the driving position on the frame side can be replaced with each other, so that a rack or a cylindrical system can be installed on the module side, and One of the sides corresponds to a driving gear or a piston.

The guiding element on one side of the assembly and the guiding element on the side of the frame together produce the guiding device. The drive position on one side of the assembly and the drive position on the side of the frame interact with the electric drive accordingly. However, the electric drive also includes a motor. The motor can be electric, pneumatic or hydraulic. It is driven by hydrostatic or hydrodynamic.

The guide element on the component side is provided on a drive element carrier, and the drive position on the component side is provided on a drive position carrier; wherein the guide element carrier or the drive position carrier is It is connected to the corresponding components respectively, which minimizes the effects of torque and force caused by extrusion in the rest of the extruder.

For example, attached plates, bolts, profile carriers and similar structures with different characteristics can be used as guide element carriers or drive position carriers. With. In particular, a drive frame or a guide frame can be used correspondingly, which are respectively connected to corresponding load components.

The connection between the guide element carrier and the driving position carrier is allowed relative to The fixed component has a specific clearance, so the most accurate guidance or the most accurate drive train is possible. Attachment means to maintain a corresponding amount of clearance, in which the operative connection between the guide element carrier and the drive position carrier and the corresponding load assembly can still be based on It is constituted in such a way that a sufficiently accurate and operable connection is maintained in the respective guiding direction or in the respective driving direction.

Preferably, this connection is achieved by a positive fit between a guide element carrier and a component corresponding to a load acting in a desired direction of the guide unit, or by driving A positive cooperation between the position carrier and the corresponding load component acting in the driver direction or the driving direction is achieved.

A corresponding positive fit can be provided by a suitable base, which is provided on the load assembly, or on the guide element carrier, or on the drive position carrier.

On the other hand, the connection can be achieved by erection or a connection that is stronger than a loose positive fit, which may provide sufficient clearance that allows a corresponding load to be removed.

Preferably, the connection system includes a plurality of bases or positive fits, and when proper clearance is maintained, it acts correspondingly from a plurality of sides, and thereby ensures a proper connection, or meets the requirements in each case. A connection with sufficient clearance as required.

It is pointed out here that in this situation, the term "attachment" between the guide element carrier and the driving part carrier means that a guide element carrier or For the setting of the driving part carrier, this method is to guide or drive the corresponding load component, which can respectively ensure the proper clearance and proper flexibility by guiding the element carrier and the driving position carrier.

If necessary, the guide element carrier and the driving position carrier may be integrally formed or provided from the same components. It is pointed out here that the corresponding load components respectively connected to at least one guide element mounted on the component part are used as the guide element carrier and can also be used as the driving position carrier. This all-in-one structure results in a highly compact structure with extremely effective minimization of one of the smallest expenditures, which minimizes the impact of the torque and force introduced by the extrusion in the rest of the extruder.

Although it is conceivable that the load assembly uses only a single guiding device corresponding to its guiding unit for guiding, this means that the single guiding device must exert all the required torque and force on the guiding alone, when When there is an adverse geometric relationship, it results in a long lever stroke, which in turn exerts a considerable load on the guide. Therefore, it is beneficial that the guiding unit includes at least two guiding devices spaced apart from each other, for example, disposed on the load assembly on opposite sides, and in principle leads to the same guiding path. This means that any moment or corresponding applied force will not grow too quickly and safely, and can ensure a more reliable and consistent guidance. Therefore, it is advantageous when each guide device includes a guide element on one side of the module and, in each case, the guide element on one side of the module is provided on one guide of the corresponding module. When the lead element carrier is mounted, its parts are connected to the corresponding components in each case.

Depending on the specific implementation, it is clear that in order to constitute a corresponding guide device to guide as efficiently as possible, a plurality of guide elements on one side of the module may also be mounted on a guide element. With.

In particular, in order to ensure a sufficiently good guidance, three, four or more guiding devices can also be connected to corresponding components; wherein, preferably, the guiding devices are arranged symmetrically to each other, such as rotationally symmetric Or mirror symmetry. It is particularly preferred to correspond to one of the squeeze axes It is symmetrical, so it is relative to the average moving direction of the extruded material through the extruder.

Clearly, depending on the specific needs, the system can also be provided with a plurality of electric drives, each of which is arranged at a distance from each other on the load assembly, wherein it can be a symmetrical arrangement as described above. Depending on the specific needs, in order to ensure corresponding operating safety, as many electric drives as guides are not required. In other cases, a plurality of small devices can be installed in a holistic manner, especially when more power is required in principle, for example, when a large squeeze is applied, so that a large driver can be omitted.

When there are a plurality of electric actuators, it is beneficial for each electric actuator to engage with one of the driving positions on one side of the module, and it is also beneficial in each case that one of the driving positions on one side of the module is set to correspond to One of the driving position carriers on the load assembly; in each case, it is connected to the corresponding load assembly separately.

The guide element carrier and / or the drive position carrier, or the at least one guide element carrier and / or the at least one drive position carrier, are beneficially connected to respective components through at least one damping element. In this case, the damping element can suppress any impact or smash and minimize the impact, and the impact or smash can be caused by the pressing process in the guiding direction or the electric driving direction.

Springs, whether they are scroll or leaf springs, leaf springs, or similar elastic components, may be used as a damping element; among them, if necessary, they can still be equipped with machinery for impact or slamming Friction element that can be converted into thermal energy. The hydraulic damping element is useful in this situation, and the hydraulic damping element has an energy removal effect through the flow between the load assembly and the driving position carrier or the guide element carrier. As such, elastic elements have proven to be highly beneficial as damping elements because they can transmit force and also have An energy removal effect.

When one of the drivers in the moving direction of the corresponding component is effective, it is installed between the guide element carrier and / or the driving position carrier on the one hand, and between the corresponding components on the other hand It is particularly easy to realize a separate attachment of a guide element carrier or a driving position carrier. Although any impact or slam in the effective direction of the driver is further transmitted, other effective impacts or slams or other directions of force cannot be transmitted through this type of driver or the transmission effect is poor.

In particular, a corresponding driver has a base on a component side or a stop on a component side, and a guide element carrier side or a drive position carrier One stop on the side, which acts by a loading method.

Preferably, the drive system interacts with the damping element so that a particularly effective decoupling can be ensured. For this purpose, the drive and the damping element system may be connected in series, for example for this purpose the damping element system may be shown as a corresponding stop or a corresponding abutment. In another embodiment, the damping element is connected in parallel with the drive train.

In order to minimize the impact of the moment and force introduced by the rest of the extruder by extrusion, an extruder is used to push a blank through a mold with a blank container and an extrusion punch. The extrusion punch is movable relative to the blank container and the die. Among them, at least one component of the extruder is electrically driven by an electric drive. The electric drive includes an electric drive gear and a rack that mesh with each other. It is characterized in that the driving gear train is mounted on a driving position carrier in an adjustable way through an eccentric wheel associated with the rack. The eccentric gear train allows the drive gear to be adjusted very accurately, independently of any gaps with respect to the rack, in order to allow any kind of impact or slam without any gaps. In particular, the recoil system can be optimally adjusted to each other.

As a corresponding component, especially a load component, has been described in detail above, and can be driven electrically in a corresponding manner, wherein, preferably, the slamming system at the transition between the load component and the driving position vehicle may be It is intercepted through the separate connection between the driving position carrier and the load assembly, but there is no great gap between the drive gear and the rack, which reacts at the transition of this separate connection.

Therefore, it is advantageous that the eccentricity of the eccentric wheel has an element on a plane that intersects the rack, so that the drive train can be moved up or away from the rack in this way.

Preferably, the driving position carrier is a motor supporting an electric driver, and more preferably an electric motor. Clearly, a hydrodynamic or static motor, but preferably a motor with a rotor, can also be used as a motor. Similarly, a linear motor can be used if it is beneficial.

However, a motor system with a rotor is particularly useful for interacting with the drive gear, so that a very simple structure can be achieved by this.

Between the electric drive and the drive gear, for example, a safety clutch may be provided, which may be provided as an overload release mechanism. In this way, the electric actuator can release any impact or slamming or other force caused by the squeezing. Preferably, such a safety clutch is constituted by the same friction clutch. However, it can also include rupture discs or blasting rods. In particular, a friction clutch or a torsional vibration damper system may also be beneficial to use as a safety clutch, because in this way the system can ensure a corresponding separation in a non-destructive manner.

In particular, the safety clutch is installed between the electric drive and a gearbox, and the gearbox is installed between the electric drive and the driving position, so that excessive force is not transmitted from the electric drive to the gearbox, and the safety clutch is To reduce or relieve the load on the gearbox and protect it.

Clearly, if necessary, in order to obtain the advantages by a corresponding cumulative method, the technical features of the solution as described above or in the scope of the patent application can be combined.

Further advantages, objects, and characteristics of the present invention are assisted by the description of the following embodiments, especially in conjunction with the provided drawings; the drawings include: Figure 1 is a schematic side view of the extruder of the present invention; Fig. 2 is a detailed diagram of a guide unit or an electric drive of the extruder in Fig. 1; Fig. 3 is between the load assembly and the guide element carrier in Fig. 2 or with the drive Schematic diagram of the structure for switching between position carriers; and Fig. 4 is a diagram showing the structure viewed from the driving position below.

The extruder 10 in the figure includes a frame 28. A portion of the frame 28 shows a cylindrical beam 64, a pair of upright beams 66, and a tie rod 68 operatively disposed between the cylindrical beam 64 and the opposite beam 66 in a known manner. The tie rod 68 includes a plurality of tension elements or pressure pieces, and the number of the tie rods 68 can be matched according to a known technical method; each tie rod system may also be an integrally formed structure.

In the case of the extruder 10, a main cylinder 60 is provided on the cylindrical beam 64 by a technique known per se. Through the main cylinder, an extrusion ram 16 can be extruded along an extruder. The shaft 54 moves to a mold 12 which is fixed to the opposite beam 66 for applying a pressing force.

Furthermore, the extruder 10 has a blank container 14, which is used to press the blank during the extrusion process. The material is enclosed and squeezed so that the material can flow out only through the die 12.

For the purpose of extrusion, the extrusion punch 16 is a relatively long design so that it can be inserted into the blank container during extrusion and can push the blank to the mold 12 via the blank container 14.

Therefore, the extruder 10 is operated as a direct extruder, which includes another embodiment of the operation as an indirect extruder, and the extrusion punch 16 is relatively short in design, and The die 12 is set on a die punch. As for more complicated die extruders, such as continuous extruders, the extrusion punches and dies in different embodiments can show a punch shape and provide more complex motion cycles.

For loading purposes and the like, the blank container 14 is axially displaceable to a pressing shaft 54 in a guide unit 20. For this purpose, the blank container 14 is connected to a container rack 72, which has a corresponding guiding device 22, which will be described in detail below.

Similarly, the extrusion punch 16 is fixed to a cross beam 70, and the guide device 22 is partially connected to the cross beam 70; and the guide device also allows guidance along the guide unit 20. Clearly, in different embodiments, different components loaded with the pressing force and the moment can also be provided in a displaceable manner along the guide unit 20 or another guide unit.

In this embodiment, four guiding devices 22 are provided on the cross beam 70 and the container rack 72 respectively, so that the tilt and the like and the structural condition in the presence of any event can be guided through the pull rod 68 lead.

In this embodiment, the cross beam 70 is still connected to the side cylinder 62, and the side cylinder 62 is also supported on the cylinder beam 54 and can be operated in the extrusion direction and the opposite direction. In this way, the cross beam 70 can be guaranteed to move axially along one of the guide units 20.

Obviously, the mold 12, the blank container 14, and the associated container holder 72, And the extrusion punch 16 and the cross beam 70 are equivalent to the load assembly 18, and the load assembly is subjected to the load caused by the force and moment caused by the extrusion during the extrusion. The latter proves to be less critical in the case of the mold 12 because it remains fixed relative to the frame; while the blank container 14 with the container holder 72 and the extrusion punch 16 with the cross beam 70 are displaced along the guide unit 20, so The corresponding load can be transmitted to the guide unit 20 and the related driver.

In this embodiment, the electric drive 32 of the blank container 14 or the container rack 72 is performed by an electric motor 52. The electric motor 52 drives a drive gear 46 through a gearbox 56 and a safety clutch 58; the drive gear 46 is Act as one of the drive positions 34 on one side of the load assembly.

The driving gear 46 is meshed with a rack 48 as a driving position 36 on one side of the frame, and a part of the rack 48 is fixed to the tie rod 68 by a fixing method.

The electric motor 52, the gearbox 56, and the driving gear 46 are fixed to a driving position carrier 38 through an eccentric wheel 50, and the driving position carrier 38 serves as a driving frame.

The drive frame or drive position carrier 38 is further used as a guide element carrier 30, and for this purpose, as a guide element 24 on the side of the assembly, a sliding block is carried, which is part of the corresponding guide device 22 As a guide element 26 on one side of the frame, the guide element 22 also includes a guide rail, and the sliding block interacts with the guide rail.

In this embodiment, each guide device 22 includes two guide elements 24 on one side of the load assembly and a guide element 26 on one side of the frame. The arrangement is perpendicular to each other and can be operated along the guide unit 20. Wherein, each guide element 26 on one side of the frame is provided with two slide rails on the pull rod 68.

The guide element carrier 30 and the driving position carrier 38 are respectively connected to the container rack 72. Therefore, in this embodiment, a damping element 40 can also be installed to the blank container 14. The damping element 40 can be configured as an elastic element 42 and a driver 44. The driver 44 can interact with the damping element 40. It can be achieved by placing the load assembly 18 on the guide element carrier 30 or the driving position carrier 38.

The actuator 44 in this embodiment includes two bases 74 on one side of the module and two bases 76 on the guide element or the driving position carrier side, and each base 74 is a damping element 40 Whereas, the base 76 can be provided by a driver attachment 78, and a part of the driver attachment 78 is disposed on the guide element carrier 30 or the drive position carrier 38. It is clear that in different embodiments, the driver attachment 38 may be integrally formed on the guide element carrier 30 or the driving position carrier 38, and the corresponding base 76 provided is provided on One side of the guide element or one side of the carrier in the driving position. It is also conceivable that in different embodiments, the corresponding damping element 40 may be provided to generate a base on one side of the guide element or one side 76 of the driving position vehicle. Likewise, the base on one side 74 of the module may be provided by a container rack 72, or a blank container 14, or a load module 18.

Clearly and suitably, the actuator 44 is also operable on only one side, which is provided to tend to transmit driving or directing force only in one direction.

Obviously, since the force applied in an axial direction passes through the damping element 40, it is parallel to the squeeze shaft 54 acting on the driver attachment 78 and is effectively absorbed. Forces that occur perpendicular to the same released base are hardly transmitted by the base, and there is only one frictional connection. It further understands that, in order to promote a stronger guidance, the damping element 40 and the corresponding elastic element 42 can also appropriately surround the driver attachment.

The load assembly 18 on the guide element carrier 30 or the driving position carrier 38 The bearing system may also be provided by a damping element, such as a rubber pad or a spring.

In this case, the guide device 22 and its guide element carrier 30, and the drive position carrier 30 or the electric driver 32 are described only with reference to a guide position or a drive position.

As mentioned above, the exemplary embodiment of this case has at least four such guiding devices 22, which are respectively connected to the container holders 72, symmetrical to the pressing direction. Clearly, in different embodiments, more or fewer guidance devices may be provided as appropriate.

Furthermore, in this embodiment, since only the guide element carrier 30 is disposed below the extrusion shaft 54, the main extrusion direction passing through the extruder 10 is also configured as the driving position carrier 38, so Sufficient drive for one of the blank containers 14 in this implementation. Clearly, in various embodiments, all of the guide element carriers 30 are also configured to drive the position carrier 38, and accordingly, an electric driver 32 is provided. It may also be used for one of the guide element carriers 30 in different embodiments.

Furthermore, it is clear that in different embodiments, a driving position carrier 38 can be provided without a guide element 24 on one side of the assembly and thus not a guide element carrier 30. It is only used as an electric drive 32.

In the situation in this embodiment, the cross beam 70 is driven by the main cylinder 60 and the side cylinder 62; in different embodiments, the cross beam 70 can also be guided along the guide unit 20, and It is guided by the electric driver 32, which is above the driving position carrier 38. At this time, the driving position carrier 38 is also the guide element carrier 30. In this embodiment, four guiding devices are installed on the cross beam 70. At this time, the cross beam 70 is not used as the driving position carrier 38, but is the same as the guide device of the blank container 14 or the container rack 72. Guide elements 26 on one side of the frame 22 interact.

Furthermore, it is clear that for other guiding components that are also subject to any pressing force and moment, corresponding guiding devices and electric drives can also be installed.

Furthermore, it is clear that the damping element 40 can be installed instead of the elastic element 42, and the damping element 40 includes a spring, such as a scroll spring or a leaf spring. It is also possible to be a leaf spring. If necessary, in order to enhance a damping effect, an additional friction device may be installed.

In this exemplary embodiment, the eccentricity of the eccentric wheel 50 displays an element that intersects the rack 48 in a plane, as shown in FIG. 4; the plane of its projection constitutes a corresponding plane. In this way, the drive gear 46 can be optimally adjusted in relation to the sides of the rack 48, and preferably, this only occurs during maintenance work, so wear can be offset if necessary. In order to achieve a corresponding adjustment, preferably, in principle, when the corresponding eccentric wheel has been appropriately known, the eccentric gear train is stuck or released.

In the present embodiment, the safety clutch 58 is provided as a friction clutch, and is located between the transmission 56 and the electric motor 52. Such a friction clutch has advantages. The advantage is that it works in a maintenance-free manner in principle, and once a slip has occurred, it does not lose its operational reliability. The gearbox 56 can also be relieved of excessive force, which can be applied by the electric motor 52.

Alternatively, if the gearbox 56 is to be protected from impact and the excessive force of the electric motor 52 is negligible relative to the gearbox, the gearbox 56 and the driving gear 46 or the driving position 34 on the component side may be used. A safety clutch is installed between them.

If necessary, in order to be able to optimize the process in this respect, a sensor can send a corresponding sliding signal. Clearly a blasting rod or disc or a torsional vibration The damper system is good for being used instead of a friction clutch. The latter can also be replaced if necessary.
