Abstract

1,011,893. Forging. ENGLISH STEEL CORPORATION Ltd. Dec. 20, 1963 [Dec. 22, 1962], No. 48534/62. Heading B3H. A large forging such as a crank-shaft or coupling is made by providing a preliminary forged workpiece having a small portion 9, Fig. 5, sandwiched between large portions 11, embracing the small portion between dies 1 and upsetting the large portions against the ends of the dies by repeated applications of the press tools. The dies are split at 4, Fig. 1, and have circular end portions 6 for securing hollow porter bars 14, Fig. 5, which are manipulated by chains 15 from an overhead crane. A single porter bar may be used. Upsetting is performed by repeated blows between upper and lower tools 16, 17 and this causes the small portion 9 to fill the die orifice. A finished crank-shaft may have journal portions 20, Fig. 6 (not shown), extending outwardly from the upset webs.
