发明名称 METHOD FOR PRODUCING A HOUSING FOR A BALL JOINT
摘要 A process is provided for manufacturing a ball-and-socket joint housing by cold forming from a blank (R), which is preferably produced from a bar or wire material and is prepared for forming. A first axial depression (1) with a diameter (D1) is first prepared by reverse cup extrusion. A second axial depression (2) with a comparatively larger diameter (D2) is subsequently prepared in the axial depression (1) by reverse cup extrusion. A diameter reduction (D3) also of the first axial depression (1) is formed in some sections by the deformation of the material during the second reverse cup extrusion.
