Abstract

The vertical reciprocating recoil sprung press punch cuts the end of a lightweight multi-cell box section in prepn. for the mfr. of e.g. window frames. In a single pressing operation the tool removes an end length of an inner web (23) and forms both a hole (24) and a slot (25) in a web (26) beneath. The tool adapts to different sections and has an adjustable stop (17) determining the end length treated. The partial exclusion of waste cuttings may be effected by a matrix support (21) with one side bevelled (22). The bevel (22) permits the recovery of cuttings from one side of the tool. The unit may have a punch (9), a floating matrix and a lower matrix (13). A stop (17) which is fixed by a screw may locate on the secondary matrix (13) by a rib engaging transverse groove (16).
