Abstract
An improved punching tool (1) has a lower tool (3), which is subdivided into a lower tool base plate (7) and a lower-tool operative part (8). The lower tool base plate (7) has a receiving face, with which uniform base areas of a plurality of lower-tool operative parts (8) are associated. The dividing place between the lower-tool operative part (8) and the lower tool base plate (9) is disposed such that all the workpiece-specific designs are present exclusively on the lower-tool operative part (8), while the lower tool base plate (7) is the same, without change, for all workpieces to be machined.
Claims10
A punching tool (1), in particular for green sheets,
- having a lower tool base plate (7), which is arranged to be supported resting on the table of a punching machine and which is embodied workpiece-nonspecifically,
- having a lower-tool operative part (8), which is embodied workpiece-specifically,
- having a linear guide device (4), which is supported by the lower tool base plate (7),
- having an upper tool base plate (34), which is supported movably toward and away from the lower tool base plate (7) by the linear guide device (4) and is embodied workpiece-nonspecifically, and
- having an upper-tool operative part (35), which is embodied workpiece-specifically or is adaptable to different workpieces.
