Abstract

The process entails successively cold-drawing, re-pressing, tempering and cutting a cylindrical metal piece (3) and may produce push-rods for automobile brake or clutch controls. The finished piece comprises a circular section rod (1) with an enlarged end 2) incorporating a perpendicular circular hole. The process is suitable for economic mass prodn. The original cylindrical piece (3), which may be of phosphated and globulised bar, is first cold drawn on a transfer-press whereby a cylindrical tail (1) is formed. A head (5), which may be cylindrical or spherical is then formed at one or mre posts on the same press. The piece is next tempered to eliminate hammer-hardening, and the head is then flattened (2) in prepn. for formation of the hole by punching or machining. The initial drawing stage may be preceeded by the formation of a bevelled end (4), and may utilise a sliding punch. A sleeve may be forec fitted in the hole.
