ABSTRACT:
An apparatus for flow-forging and sheet-metal rubber-forming a shaped part from a work includes two members spaced from one another which define a pressure zone therebetween. First and second dies disposed between the members clamp the work therebetween, and a roller conveyor transports one die along a transport direction. The dies are driven to and from the pressure zone, and one die includes a plurality of adjoining pressure-transferring elements. In a plurality of self-adjustable matching devices, each is interposed between the roller conveyor and a pressure-transfer surface of a corresponding pressure-transferring element. Each matching device automatically adjusts its position, as it passes through the converging pressure zone. A longitudinal member of each matching device has a substantially plane surface of a width exceeding at least a center-to-center spacing of two adjoining rollers of the roller conveyor. Substantially each longitudinal member is constrained to pivot about an axis substantially parallel to the plane surface. The pressure-transferring elements, which move in the transport direction, also move from one member towards another, while being transported through the pressure zone. As a gradually and smoothly increasing pressure is applied to the work by the members during the transport of the dies through the pressure zone, any recess flow-forged in the shaped part is smooth and free of any ridges.
