Punching device for separation of shaped parts, has aligning device aligning punching segments and including actuators for coarse alignment of segments relative to reference point and fine adjustment of coarsely aligned segments

摘要

The device (15) has punching segments (3-6) that are limited to each other with a shaped part cutting die that is arranged in a grid, where the punching segments are independently controllable or regulatable. An aligning device aligns the punching segments and includes actuators (7-14) for coarse alignment of the segments relative to a reference point and fine adjustment of the coarsely aligned segments. The individual segments are automatically adjusted by varying shrinkage of foils (1) by an optical system.
