Abstract

PURPOSE:To reduce the production cost and to improve productivity by making a partially fabricated item forming a spherical head part and connection hole via cold forging on a metal circular columnar blank and executing other workings by cutting. CONSTITUTION:A small diameter wall part 1'' is formed at one end with the cold working of a short-sized circular columnar metal blank by a die D1 and punch P1, and a truncated conical shape is then worked via a die D2 and punch P2. A partially fabricated item is obtd. by forming a spherical head part 2 and connection hole 4 by a punch P3 and the die D2. An annular recessed groove 7 is respectively subjected to cutting with the working by flat faces 5, 5', a bolt hole 6 and boring bit for the partially fabricated item of after cold forging. The cutting is remarkably contracted by executing a series of cold forgings and the waste of materials is reduced. Consequently the production cost is reduced and productivity is improved.
