Abstract
The apparatus comprises a metal moulding tool (1) and a ram (5). The apparatus also includes packed steel balls (6) introduceable into a hollow body (7) to be shaped, and plugs (9). The steel balls (6) have only a small cross-section and are tribologically prepared. By applying pressure in the transverse direction of the hollow body (7) with the ram (5), the steel balls (6) are displaced and press the wall of the hollow body (7) into a moulding cavity (3) of the moulding tool (1). In an alternative apparatus, rams (11, Fig. 3) introduced into a tube (7) to be shaped displace the steel balls (6) and press the tube wall (12) into a cavity (3) in the moulding tool. The steel balls are tribologically prepared by oiling, or by dusting with graphite. A mixture of steel balls having differing diameters may be used.
