Verfahren zur Herstellung von hochfesten Schraubenfedern sowie Anlage zur Durchführung des Verfahrens

摘要

The spring manufacturing process starts with spring steel rods, the surface of which is machined. each rod is then cold-wound into a coil spring. The wound coil spring is then austenized by induction heating. It is finally hardened by quenching in an oil bath. During the induction heating, it may be offset in rotation about its longitudinal axis.
