ABSTRACT:
The invention concerns an impact machine for forming a body with desired shape of a formable working material through impact action in a forming operation, said impact machine comprising a machine stand (6), an upper unit which comprises either a lower impact unit (3), which comprises a counter-impact device, or a stationary anvil, and a central unit between the upper and the lower units. The central unit (4) comprises one or more carriers (30), each of which containing and carrying one or a plurality of identically equal tool units (32), each of which comprising a die (34) with a mould cavity (46) for the working material (90) intended to be formed, said carriers including at least one carrier which is stationary during the forming operation and which contains at least one such tool unit, and that motion devices (7) are provided for indexing the carrier or carriers in a horizontal plane for positioning the tool units in different function stations (1-V), comprising a forming station (II) and at least one more station.
