Abstract

The machine for manufactring bolts and the like as disclosed includes a frame, a number of shaping stations, more particularly for upsetting and trimming of blanks, said machine comprising a reciprocable main carriage mounted for reciprocation in the frame and carrying upsetting heads adapted to cooperate with dies mounted in a die plate fixed in the frame of the machine, a reciprocable trimming die adapted to cooperate with a trimming punch attached to the die plate, means for reciprocating the main carriage and trimming die to carry out a series of upsetting and trimming operations with respect to workpieces handled by the machine, the main carriage including means for effecting upsetting operations at each stroke and the trimming die effecting a trimming operation on an upset article at each working stroke, and means for varying the stroke of the trimming die relative to the stroke of the main carriage to start the trimming operation prior to the starting of the upsetting operation.
