Abstract (en)
An apparatus for flow-forging and sheet-metal rubber-forming a shaped part from a work includes two members (78, 81) spaced from one another which define a pressure zone therebetween. First and second dies (24, 26) disposed between the members (78, 81) clamp the work therebetween. One die (24) includes a plurality of adjoining pressure-transferring elements (28). In a plurality of self-adjustable matching devices (34), each is interposed between the roller conveyor (110) and a pressure-transfer surface (30) of a corresponding pressure-transferring element (28). Each matching device (34) automatically adjusts its position, as it passes through the converging pressure zone. As a gradually and smoothly increasing pressure is applied to the work by the members (78, 81) during the transport of the dies (24, 26) through the pressure zone, any recess flow-forged in the shaped part is smooth and free of any ridges.
