Definitions
- the invention relates to a device for shaping, in particular for cold shaping, in this case in particular for cold extrusion, a workpiece, which has a shaping die and a feed device, by means of which a relative movement between the workpiece and the shaping die can be generated, and a method for shaping, in particular one Cold forming, a workpiece in which a Relative movement between a workpiece and a deformation die is generated.
- Such a device and such a method are generally known and therefore do not have to be described in more detail.
- a disadvantage of the known device and the known method is that high feed forces are required to achieve the desired cold deformation of the workpiece.
- the device provided for carrying out the method has a device with which the anvil can be moved back and forth.
- the device has a frequency generating device which interacts with the feed device, by means of which the relative movement between the workpiece and the deformation die generated by the feed device can be modulated such that after a forward stroke in which the workpiece is in the feed direction and / or the deformation die traverses a first stroke, in a subsequent backward stroke a movement of the deformation die and / or the workpiece in a direction opposite to the feed direction can be carried out by a second stroke.
- the relative movement between the workpiece and the deformation die generated by the feed device is modulated such that after a forward stroke in which the workpiece and / or the deformation die passes through a first stroke in the feed direction, a movement takes place in a subsequent reverse stroke the deformation die and / or the workpiece can be carried out in a direction opposite to the feed direction by a second stroke.
- the measures according to the invention advantageously achieve that the deformation, in particular cold working, for. B. one
- a workpiece feed force required to achieve a defined final deformation of the workpiece is significantly lower than with a conventional device. This not only has the effect that the energy required to drive the device according to the invention is reduced and significant energy savings are achieved.
- the lower forces occurring when deforming with the device according to the invention also permit a lighter and therefore less expensive construction of the device according to the invention, as a result of which the production costs are also reduced.
- the "hammer-like" The application of force to the cold-formed workpiece by the intermittent, stroke-like feed movement advantageously allows high-quality cold forming with minimal effort and wear. Another advantage is that the workpiece is subjected to only slight axial forces, so that buckling and deformation, also in the form of bulges, are largely prevented.
- FIG. 1 shows a first exemplary embodiment of a device
- Figure 2 shows a second embodiment of a device.
- the first exemplary embodiment of a device 1 for cold forming, in particular for cold extrusion, of a workpiece 2 shown in FIG. 1 has a deformation die 3 which can be moved relative to the workpiece 2 by a feed device 5.
- the feed device 5 thus generates a relative movement between the deformation die 3 and the workpiece 2 clamped in a clamping unit 7. If the deformation die 3 is moved by the feed device 5 in its feed direction P against the workpiece 2 clamped in the case shown here, this occurs Workpiece 2 into the deformation die 3 and is cold-formed in a manner known per se.
- the movement running in the feed direction P is modified by a frequency generating device 10 such that the deformation die 3 instead of a uniform one in the feed direction P executes a stroke-like movement, in which it is provided that after a forward stroke directed in the feed direction P, in which the deformation die 3 is moved forward by a first stroke, the deformation die 3 in a subsequent reverse stroke through the feed device 5 is withdrawn by a second stroke. In the subsequent forward stroke, the deformation die 3 is moved forward again, specifically beyond the end point of the preceding forward stroke.
- the deformation die 3 has a higher kinetic energy than it does when it hits the area of the workpiece 2 to be machined in the next step
- Continuous application of force is the case, since the return movement of the deformation die 3 prior to its renewed acceleration by the feed device 5 in the feed direction P has the effect that during the feed movement the deformation die 3 moves along the region of the workpiece 2 that was cold-deformed in the previous forward stroke and this region essentially can go through without resistance.
- the retraction of the deformation die 3 before the next step of the cold deformation process has the effect that an improved supply of lubricating oil, which is supplied by a lubricating oil supply device 8 shown schematically in FIG. 1, is improved.
- the frequency generator 10 generates the forward movement of the deformation die 3 in Feed direction P modulating frequency is in the range of about 5 to 30 Hz and is preferably 10 to 20 Hz.
- the second stroke path of the backward movement of the deformation die 3 is essentially only half of the first stroke path provided during the feed.
- the frequency generating device 10 can operate hydraulically, pneumatically or mechanically, although electromagnetic excitation of the frequency modulating the feed movement of the feed device 5 is also conceivable for certain cases.
- the frequency generating device 10 into the feed device 5, so that the feed movement generated by the feed device 5 is directly modulated. This can be done in particular by the fact that the oil supply to a feed cylinder 5 'of the feed device 5 is regulated servo-hydraulically or proportionally hydraulically, so that the cylinder 5' causing the feed of the deformation die 3 oscillates periodically.
- the exemplary embodiment of a device 1 'shown in FIG. 2 essentially corresponds to the device 1 of the first exemplary embodiment, so that the same parts can be provided with the same reference numerals and no longer have to be described in more detail.
- the essential difference between the two exemplary embodiments is that in the device 1 * the deformation die 3 is arranged in a stationary manner, while the workpiece 2 is axially displaceable relative to the deformation die 3. Accordingly, the feed device 5 and the frequency generating device 10 cooperating with it act on the workpiece 2 or on the clamping unit 7 which clamps the workpiece 2.
