Abstract

312,571. Friedman, J. H. Nov. 1, 1928. Upsetting; forging-dies. -In forging articles from the bar by upsetting, the gripping-dies 2 have a cutter 3 which only partly severs the stock, leaving a rounded corner at 4. In a subsequent stage this corner is filled out as by the action of a punch 8, Fig. 4, and on completion of this operation the blade, 7 is further advanced to complete the severance. Porter bars.-The main portion of the stock serves as a porter bar during the successive forging stages.
