Abstract

The invention discloses a high-frequency surface quenching machine and relates to a processing and heat treatment device. The high-frequency surface quenching machine comprises a base, a support, a self-rotating motor, a high frequency machine and a water tank, and is characterized in that a lifting lead screw is arranged on the base, a lifting motor is arranged on the lifting lead screw, the lifting motor can control a lifting sliding plate to slide on the lifting lead screw, a material-jacking cylinder and the self-rotating motor are arranged above the lifting sliding plate, the lower end of the material-jacking cylinder is connected with an upper tip, the self-rotating cylinder is connected with a transmission shaft, a small belt wheel is arranged at the bottom end of the transmission shaft, the small belt wheel is connected with a big belt wheel through a belt, a lower tip is arranged above the big belt wheel, and a water spray head and a high-frequency heating coil are arranged between the upper tip and the lower tip. The high-frequency surface quenching machine can solve the problem of non-uniform quenching hardness of the surface of a workpiece of the high-frequency surface quenching machine in the prior art, has low cost and convenient use and can ensure the uniform quenching of the surface of the workpiece.

Description

technical field [0001] The invention relates to a processing heat treatment equipment, in particular to a high-frequency surface quenching machine. Background technique [0002] Shaft parts for molds need to have high hardness and wear resistance but at the same time need to have good toughness. This requires surface quenching to obtain high hardness on the surface, while the inner layer maintains the original low hardness to maintain good toughness. High-frequency quenching machine refers to a heat treatment method that uses high-frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece at a certain depth, while the core basically maintains the structure and performance before treatment, so it can obtain a combination of high strength, high wear resistance and high toughness. And because of local heating, it can significantly reduce quenching deformati...
