Abstract

1285298 Punching HOUDAILLE INDUSTRIES Inc 15 Dec 1970 [22 Dec 1969] 59508/70 Heading B3W A punch has a resilient washer-like tip 29 of which the outer periphery 39 is normally spaced from the end face 34 of the punch body 32 but is deflectable towards it by engagement with a workpiece 36. As the diameter of the tip decreases when the tip returns to its normal disposition after punching, it ejects the slug 36a and dispenses with the need for a stripper. Shapes of tip described include frusto-pyramidal or -conical, part cylindrical and undulating. Alternatively a flat tip may be used with a punch body having a convex end face. Several such punches can be mounted close together in a sub press mechanism. The punch is retracted by a spring 27.
