Verfahren zur Herstellung eines Gelenkgehäuses mit einem angeformten Schaft

摘要

A blank (R) preferably of wire, has a spherical fatter part (V) on one end and is cold formed. An axial recess (1) with a diameter exceeding that of the internal thread and with a length exceeding the axial length of the threaded part is produced in the shaft of the blank by backward can extrusion. The threaded part is reduced to the diameter (3) of the threaded core by simultaneously forming the casing surface to a key surface (2) The outer and inner shape of the link housing (8) are produced by cold forming to the side of the axial direction of the shaft (9).
