<p>A trimming tool for trimming drawn parts over their complete periphery and for the simultaneous transverse cutting of the waste strip which has been cut off achieves complete and fragment-free transverse cutting of the waste strip by way of a low-maintenance, reliable tool which does not limit the space for introducing and removing the workpiece. The transverse cutting takes place by rectilinear further motion of a transverse cutter integrated in a fixed location in the upper tool. Its shear edge is freed in ample time by a controlled escape motion of a make-up cutter. The make-up cutter permits a complete and clean trim cut to be carried out on the workpiece and also permits the shear edge of the transverse cutter to extend right up to the trim shear edge. Because of the rectilinear downward motion of the transverse cutter, the waste strip is also sheared off cleanly and without cracks as far as the innermost trim cut edge.</p> |
