Automobile part, manufacturing method for same and manufacturing device of same

摘要

Provided is a manufacturing apparatus for an automobile part, comprising: a conveying path (20) for transferring an outer joint member (10) which is made of a metal and has an outer surface coated with a coating agent after induction quenching; and high-frequency induction coils (21, 22) arranged along an automobile part transferring direction of the conveying path (20), for simultaneously performing tempering of the outer joint member (10) and baking of the coating agent.

主权项

1. A manufacturing method for an automobile part, comprising:
induction quenching an automobile part made of a metal; applying a coating agent onto an outer surface of the automobile part after the induction quenching; performing tempering of the automobile part and baking of the coating agent simultaneously by high-frequency induction heating for a cycle time; and quenching the automobile part after the high-frequency induction heating for a cycle time, wherein the cycle time of the high-frequency induction heating is synchronized with the cycle time for the quenching by either increasing a length of an induction coil used in the high-frequency induction heating relative to the cycle time for quenching, or increasing a number of impartations of high-frequency induction heating relative to the cycle time for quenching.
