Abstract

A swan necked impact punch for perforating sheet materials where the elastic coupling between the tool driving head and the workpiece stripping collar comprises an elastomeric sleeve. Pref. the sleeve has dove tailed anchorages with the driving head and the stripping collar. Pref. the stripping collar has an insert bush for guiding the punch tool. Text suggests that the elastomeric sleeve is a polyurethane rubber and that the driving head and the stripping collar are moulded in a polyamide material. Simpler to make, assemble and align than conventional stripper collar systems using phased stacks of annular dished metal springs.
