ABSTRACT:
A multi-stage cold forging machine including a parts forming aid unit, which has a number of aid pins corresponding to that of the forging dies, the pins being adapted to retain a forged blank against a knockout pin slidably housed in the dies, and transfer it from the respective stage to the next. The blank is progressively refined as it is transferred from stage to stage. The aid pins are operated in such a manner as to stand out of the way of the hammers moved by a ram.
