Abstract

The invention discloses an induction heating quenching and tempering system which is used for quenching and tempering heat treatment of car rack blanks or connecting rod rods. The system comprises an adjustable conveying system and an electrical control system which are mutually connected, wherein a feeding mechanism, an induction hardening heating unit, an adjustable spray coil type quenching and cooling mechanism, an induction tempering and heating unit and a discharging structure are sequentially arranged on the adjustable conveying system; the adjustable conveying system is used for advancing and rotating of workpieces connected one after another; the electrical control system is used for controlling the induction heating quenching and tempering system. The system can effectively improve the uniformity and precision of the workpiece heating, and allows the workpiece to be more uniformly cooled and have small, even no, deformation. When the workpiece is subjected to tempering, no deformation is caused during uniform cooling. Due to the adoption of the system, the rigidity difference between the surface and core of the automobile rack blank is small, deformation is small or even can be avoided, and mass and stable continuous production is realized.

Description

technical field [0001] The invention relates to a metal heat treatment system, in particular to an induction heating quenching and tempering system, which is suitable for quenching and tempering heat treatment of medium and high-grade automobile rack blanks and other similar high-demand connecting rod rods. Background technique [0002] Induction heating is mostly used in many fields such as surface quenching of industrial metal parts, metal smelting, bar material diathermy, and tool welding. Diathermic melting effect. The principle of induction heating is that when current flows through the induction coil, an alternating magnetic field is induced in the metal parts passing through it. This magnetic field induces eddy currents in metal parts. When this current flows through the metal parts, it generates resistance heat. Thus, rapid heating of metal parts is realized. [0003] In the prior art, the steering gear of mid-to-high-end cars has been developed from the hydrauli...
