Compared with the prior art, the follow-up intermediate-frequency inductor has benefit effect that 1) powder frequency quenching of same-type multi-specification working pieces can be satisfied; 2) the position of the induction head can be changed along with the change of the lengths of working pieces in quenching procedures, thus, homogeneity of integral surface rigidity and performance of super-long members is realized.

Description

technical field [0001] The invention relates to the field of heat treatment tooling, in particular to a follow-up intermediate frequency sensor for ensuring the uniformity of quenching of super-long special-shaped parts. Background technique [0002] Intermediate frequency quenching is mainly used for surface quenching of industrial metal parts. It is a metal heat treatment method that generates a certain induction current on the surface of the workpiece, rapidly heats the surface of the part, and then rapidly quenches it. When the workpiece is quenched at medium frequency, moving the workpiece or the sensor requires a stable distance between the sensor and the surface of the workpiece. The conventional sensor is installed on the quenching equipment, and the workpiece or sensor moves according to a fixed track to maintain a stable distance from the workpiece. . Ordinary workpieces can basically meet the requirements on conventional intermediate frequency quenching equipment...

AI Technical Summary

Problems solved by technology

For the flat bulb steel over 5 meters, the total length deformation can reach 15mm. For the intermediate frequency quenching of ordinary fixed inductors, there will be a large distance change, or even scratching, which will affect the intermediate frequency quenching quality of the flat bulb steel.

[0004] The conventional method is to correct the workpiece first, and then heat it through the inductor coil, but this solution requires a mechanical transmission mechanism with a complex structure, or it can be realized by a numerically controlled floating mechanism, but the equipment is expensive and the working state is not very stable.
