Description

Mold Surface Induction Hardening Machine Tool technical field The invention relates to a mold surface induction hardening machine tool for quenching various mold surfaces by utilizing the principle of medium and high frequency induction heating metal surfaces, and belongs to the technical field of metal material surface heat treatment equipment. Background technique Dies used for sheet metal stamping, especially medium and large sheet metal stamping dies, in order to ensure the stamping quality and the service life of the die, the surface of the die must be quenched to increase the hardness of the die surface. In the prior art, two methods are usually used for the heat treatment of the mold surface: ① flame quenching method, the main disadvantage of flame quenching is that the heating time is long, the deformation of the mold is large, and the scale is easy to form on the surface of the mold, which affects the precision of the mold The quality of flame quenching cannot be ...

Problems solved by technology

In the prior art, two methods are usually used for mold surface heat treatment: ① flame quenching method, the main disadvantage of flame quenching is that the heating time is long, the deformation of the mold is large, and oxide scales are easily produced on the surface of the mold, which affects the precision of the mold The quality of flame quenching cannot be guaranteed, and the work efficiency is low and it is difficult to carry out large-scale production; moreover, it is difficult to control the flame quenching temperature, the uniformity of the quenching surface is poor, and problems such as too low hardness and cracking are prone to occur, thereby reducing the precision and service life of the mold

②Using laser heat treatment numerical control equipment for quenching, due to the laser spot itself, the heat treatment process is lengthy, the processing efficiency is low, and the laser quenching depth is generally between 0.05-0.20mm, which cannot meet the process requirements of mold surface heat treatment

Since the laser spot cannot stay on the same part of the workpiece twice, programming and operation are also very troublesome
