Definitions
- this at least two-part tool can also comprise a wiper in a known manner.
- the transmission element is designed as a slide that can be moved and reset transversely to the working direction of the tool. Sliders can be brought into the working position and from this back into the ineffective position in a particularly simple manner.
- Pneumatic or hydraulic working cylinders are particularly suitable as adjustment devices. But electrical displacement is also easily possible. In the case of working cylinders, double-acting versions are expediently used.
- the transmission elements transmit the working stroke of the press bear to the punch or the ram, they must also allow a transverse displacement in the direction of the punch stroke in addition to their adjustment in the working direction.
- the transmission element itself can be displaced in two directions, which are preferably perpendicular to one another, with respect to the device or a device frame.
- the displacement takes place under the press bear or the like.
- the entire transfer element is then displaced in the punching direction by the latter. This means that the longitudinal guide for the displacement of the transmission element into the working position and back again on a device frame or the like must be mounted up and down, so it is not fixed to the device.
- Each machining unit 6 is provided with a lower tool holder 11 for the lower part 12 of an at least two-part machining tool and an upper tool holder 13 for an upper tool part 14. Since all processing units are used for punching in the exemplary embodiment, each processing tool is a punching tool with at least one die 12 and a punch 14. The cross sections of the latter can be found, for example, in FIG. 2. The tool holders for the tool parts and the Be consolidation of the latter are designed in a known manner.
- the tool holder 13 for the punch 14 is located in a plunger 15 which is slidably mounted in the frame 7 in the direction of the double arrow 16. The upper end of the ram protrudes beyond the top of the frame 7 or is connected to a corresponding extension.
