ABSTRACT:
A progressive stage forging machine is provided for forming an article in stages by means of a plurality of dies and cooperating punches, carried on a ram, wherein more than two forging blows are required to complete the forming of the article. The invention particularly provides a forging machine of the three-blow type having three punches and three cooperating dies, wherein two of the dies are carried on a member to permit alternating changes of position of those two dies, thereby eliminating a transfer mechanism between the two dies and achieving a one hundred percent increase over the production rate of presently available forging machines of the three-blow type.
