发明名称 Stripping apparatus
摘要 Apparatus, for stripping an article from an axially reciprocable punch, of a kind having a plurality of segments surrounding the punch, each of said segments having a working surface resiliently urged radially inwards towards the punch and engaged with a piston, said piston being supported by fluid means for limited motion in a piston plate, parallel to the axis of the punch, to enable the working surface of the segment to contact the edge of the article before stripping wherein the improvement resides in a fixed guide means to confine a pivot portion of each segment for pivotal movement in a plane radial to the punch, individual biasing means to urge each segment substantially longitudinally towards the punch, and a cam ring having a surface which engages with a heel portion of each segment to guide the working surface thereof substantially parallel to the punch to engage with the article to be stripped. In one embodiment, return springs act against the segments to permit each segment to be lifted by the article during the forward stroke and retract into the patch of the article for stripping during the return stroke. The fluid used to support the pistons may be provided from the lubrication system of the press.
