Abstract: A multi-tool is a constituent part of a punch device, in particular of a turret punch press. An upper tool part has a plurality of upper tools which are activatable from a head side via a machine pusher of the punch device for workpiece-machining purposes. A lower tool part has a plurality of lower tools. A workpiece is arrangeable between the upper tool part and the lower tool part. In each case one of the lower tools interacts with an associated upper tool. The number of the upper tools is greater than the number of the lower tools. This results in a multi-tool for extending the possible uses of a punch device.

Abstract: The invention relates to a die for a punching device. The die comprises a die base body and a workpiece support body, which is provided on the die base body, to support a workpiece to be machined as well as a cutting to length mechanism for cutting a workpiece part of the workpiece to length. The cutting to length mechanism has a cutting to length element and a counter-cutting to length element for cutting to length interaction with the cutting to length element by several cutting to length strokes. The cutting to length element and the counter-cutting to length element can be displaced relative to one another between a cutting to length position, in which the cutting to length element and the counter-cutting to length element interact with one another so as to cut to length, and an open position, in which the cutting to length element and the counter-cutting to length element are spaced apart from one another. Furthermore, the die has a guide mechanism to guide the workpiece part.

Abstract: A multiple tool is provided for a punching device. The multiple tool includes a driving mechanism, displaceable in a punching direction, with a driving head for driving the driving mechanism by the punching device and a driving body connected to the driving head. The multiple tool further includes a punching tool magazine, which is connected to the driving mechanism, with a guide body, and a plurality of punching tools guided in the guide body. The punching tools in each case have an effective punching length for punching a workpiece to be machined. The driving body cooperates in each case, during punching use, with one of the punching tools to drive it. The multiple tool also includes a mechanical punching length testing mechanism to test the effective punching length of the punching tools.

Abstract: A punching tool has a safety device prevents a punching die from being undesirably released from a guide housing when the punching tool is gripped at the head. The safety device has a base guide body securely mounted relative to the punching die at least with respect to a gripping force direction acting on the punching die and a counter guide body securely mounted relative to the housing at least with respect to the gripping force direction. The guide bodies are designed to ensure a secure interaction in at least one retaining relative circumferential position while allowing release of the punching die from the guide housing in the gripping force direction in a release relative circumferential position displaced relative to the retaining relative circumferential position in the circumferential direction about the longitudinal axis. As a result, an unwanted release of the punching die from the guide housing is securely prevented.

Abstract: A stamping tool has a stamping punch for forming at least one punched hole in a workpiece. The stamping punch is guided in a guide housing along a stamping displacement movement. The stamping punch has a stamping element and a head element, which is connected with the stamping element by means of a screw connection. A length of the stamping punch between a head front face and a stamping surface, which closes off the stamping element at the front, can be set by means of the screw-in depth of the screw connection. An unlocking body, which is freely accessible from outside of the guide housing can be displaced between a locked position, in which the screw connection is blocked, and a screwing position, in which the screw connection is released. The result is a stamping tool with a simplified length adjustment.
