Metal laser deep-layer quenching process

Abstract

One kind of metal laser deep layer quenching craft, through must process the area surface spreading alloy extinction coating after the metal, according to processes the area choice certain facula the light beam to carry on laser processing, simultaneously, blows the metal surface laser partial with the certain current capacity gas sphere of action, and with the liquid cooling laser sphere of action periphery, causes the metal hardening level quenching depth to achieve 0.7~~3mm. The invention has solved the metal induction heating time deformation, enhanced the metal skin hardness, simultaneously has solved an ordinary laser quenching hardening depth shallower problem.

Description

technical field

[0001] A metal laser deep quenching process, suitable for surface quenching and hardening of metal materials, especially for parts with complex shapes and parts that do not allow deformation, such as the surface layer of large and medium-sized gears, the inner and outer rings of large bearings, and the processing of tool blades, etc. . Background technique

[0002] The current metal processing usually adopts the method of induction heating and quenching to improve the surface hardness of the metal. Although the depth is relatively deep, it can reach 1-3mm, but the surface will melt during heating, which not only destroys the metal surface finish, but also deforms the workpiece greatly. The production of the induction coil is complicated, especially the part of the inner cavity of the workpiece with complex shapes, which is difficult to harden.

[0003] Laser hardening metal processing technology is also widely used at home and abroa...
