摘要

High-quality manufacturing and reduced material consumption during machining have come to be at the focus of attention in the field of parts production. Hence, cold-forging - also called cold-hammering or swaging - is gaining in importance. Even the most complicated inner contours can be produced in a cost-effective manner and to the highest possible degree of precision by this method. For years, cold-forging has been an essential step in the manufacturing lines of the automotive industry. Precision and accuracy in parts manufacturing are absolutely essential. The valve body and control bush sections must be closed on both sides. In conventional manufacturing processes, this is achieved through the insertion of metal sealing rings, which not only requires additional machining and set-up operations, but also presents the risk of leakages. Compared to the conventional method of manufacturing components for power-assisted steering systems, the GFM cold-forging process offers the following advantages: complicated inner contours are made of a single part; maximum precision of the inner contour; high degree of automation; lower tool wear and minimum tool costs; reducted QC expenses; easy forming also of high-strength materials; minimum machining oversize.
