Abstract
Abstract In this apparatus a plurality of angularly spaced punch assemblies are disposed about a tubular blank-holding means, each punch assembly including: a ram, a ram guide and at least one punch means interconnected with the radially inner end of each ram. An annular member is disposed about all the assemblies and adapted to oscillate in a plane at right angles to the plane of motion of the rams and punch means. Individual cam means are connected to the annular member and each cam has a cam-face disposed angularly with respect to the plane of oscillation of the annular member. Each cam-face is in sliding, interlocked engagement with a ram-face which is disposed at an angle complementary to the angle of said cam-faces. By this arrangement, force from the plane of oscillation of the annular member is converted to force in the plane of movement of the rams and punch means.
