Abstract

539,413. Making shell forgings. NICHOLSON, V. R. Nov. 30, 1939, No. 32192/38. [Classes 83 (ii) and 83 (iv)] Billet-piercing.-In the manufacture of shell forgings a billet is provided with an axial bore, has a preliminary drawing hot, and is finished to size by cold drawing. In piercing the billet, the main punch 2 is kept central by a coaxial punch 1 that has a rapid shut stroke reciprocation superposed on the piercing movement. The punches may be hollow for the circulation of cooling fluid.
