Abstract

The invention relates to a spring thermal processing device. The invention discloses a spiral compressed spring rotary-disc-type planar induction thermal processing device which comprises a rack; a worktable is arranged on the rack; a rotary disc is arranged on the worktable; multiple spring guide pillars are arranged on the rotary disc; the spring guide pillars sequentially pass through a material feeding station, a thermal processing station and a material discharging station along with rotation of the rotary disc; a material feeding mechanism and a thermal processing mechanism are sequentially arranged on the periphery of the rotary disc; the material feeding mechanism corresponds to the material feeding station; and the thermal processing mechanism corresponds to the thermal processingstation. The spiral compressed spring rotary-disc-type planar induction thermal processing device provided by the invention is high in efficiency and good in heating effect; and the technical problems in the prior art that the heating effect of springs is not ideal and efficiency is low are solved.

Description

technical field [0001] The invention relates to a spring heat treatment device, in particular to an induction heating heat treatment device for automobile clutch springs. Background technique [0002] The metal quench hardening process is a standard process used in spring manufacturing. Most of the current springs are formed by cold rolling process, and then subjected to stress relief and tempering process. [0003] There is also a heat treatment process of induction heating after cold coil forming. The induction heating process occurs by inducing an electromagnetic field in the conductor material of the spring. Eddy currents are generated in the conductor material, and the electrical resistance of the conductor material causes Joule heating. If desired, induction heating can be used to heat the steel to its melting point, which is sufficient to austenitize the steel product. [0004] Induction heating heat treatment has the advantages of fast heating speed, grain and st...
