Abstract A machine for cold forming workpieces in which workpieces are subjected to a sequence of work operations performed by a bank of co-operating tools and dies, therebeing transfer means for transferring each workpiece through successive work stations in the bank so as to be subjected sequentially to the action of successive co-operating tools and dies. The machine has two such banks operating 180* out of phase and the transfer means of both banks are carried by a common reciprocable slide, the arrangement being such that, in one direction of its reciprocating movement, the common slide moves the transfer means of one bank in a direction which advances the workpieces in that bank to successive work stations while the transfer means of the other bank are returning, and, in the other direction of reciprocating movement of the slide, the transfer means of the other bank advance the workpieces in the other bank while those of the one bank return.
A multi-stage forming machine of the type defined, which machine comprises: first and second banks, each having a plurality of dies, associated toolholders, workpiece-gripping means and transfer means; means for reciprocating the toolholders of said first bank substantially 180* out of phase with the toolholders of said second bank; a reciprocable transfer slide common to the transfer means of both said banks; the arrangement being such that when the said reciprocable transfer slide is moving in one sense the workpiece-gripping means of the said second bank are returning, and when the said common reciprocable transfer slide is moving in the opposite sense the workpiece-gripping means of the said first bank are returning while the workpiece-gripping means of the said second bank are advancing; the said common reciprocable transfer slide comprising first and second members, said first member associated with the said workpiece-gripping means of said first bank and said second member associated with the said workpiece-gripping means of said second bank, said first and second members being linked together for movement in unison by an adjustable linkage which provides for relative adjustment of said first member and said second member in the direction of their reciprocation.
