Problems solved by technology

[0005] However, at present, the use of medium frequency induction heating furnaces for heat treatment is basically used in steel mills, round steel and gear industries. There is no such equipment in the forklift fork industry to complete heat treatment. Therefore, we refer to the heat treatment equipment for forks. Improvement to solve the following problems in the heat treatment process of the fork: the heating efficiency of the existing heating furnace for the fork is low, the energy consumption is high, the hardness of the fork after quenching is low and inconsistent, and the angle of the fork is different from that of the fork Inconsistent plane deformation, etc.

Description

technical field [0001] The invention relates to the technical field of fork heat treatment processing, and more particularly, to an intermediate frequency induction heating process for fork processing. Background technique [0002] During the processing of the fork, the straight fork blank needs to be bent to the required right-angle structure fork to form the L-shaped steel member, and the L-shaped steel member needs to be heat treated to improve the load Physical properties of the fork. [0003] In the forklift and fork industry, resistance furnaces and natural gas furnaces are generally used for heat treatment of forks. The above two heating furnaces are used to heat the forks, which require manual handling of the forks, which is labor-intensive. The energy consumption of the fork is high and the efficiency is low. Moreover, after the fork is heated by the above two heating furnaces, the hardness performance of the fork is often uneven, and the surface hardness of the fo...
