Abstract

The invention provides a clamping device for a high-frequency heat treatment process. The device comprises a lower positioning assembly and an upper positioning assembly which are arranged in a vertical direction, wherein the lower end of a to-be-treated part in a length direction is placed on the lower positioning assembly, the upper positioning assembly can adjust a fixing position in the vertical direction to clamp the upper end of the part, and an induction coil can move in the vertical direction to penetrate through the two ends of the part. The device has the advantages that the part is supported through the lower positioning assembly, and the upper positioning assembly is matched with the upper end of the part to enable the part to be kept vertical, so that the part does not bear too large pressure, arching deformation of the part is prevented, the part is not subjected to the effect of torsional force or pressure in a circumferential direction, and the torsional deformation of the part is reduced; and the induction coil can penetrate through the whole part, so that the part is integrally quenched, and the whole part can be subjected to heat treatment.

Description

technical field

[0001] The invention relates to the technical field of heat treatment, in particular to a clamping device and method for a high-frequency heat treatment process. Background technique

[0002] As the lightweight goal of automobile manufacturers is getting higher and higher, components with light weight and high strength have become the development trend of the automobile industry. The high-frequency heat treatment process uses a high-frequency induction coil to heat the part to about 900 ° C, and then cools the part with a quenching liquid to eliminate the stress concentration generated during the forming process, improve the overall strength of the part, and the fatigue resistance of the part Require. At present, most of the high-frequency heat treatment is positioned at one end, or the parts are directly placed on the tooling made of high-temperature resistant materials such as ceramics. During the heat treatment process, the parts undergo complex comprehen...
