Quenching system and method applied to workpiece induction quenching

Abstract

The invention discloses a quenching system and method applied to workpiece induction quenching. The quenching system comprises a sliding component, a quenching bracket, a water receiving tank, an induction coil heating device, a transformer, a quenching liquid water tank, a cooling water tank and a refrigeration industrial air conditioner, wherein the induction coil heating device is electrically connected with the transformer; a quenching liquid spray pipe is arranged on the sliding component; the water receiving tank is arranged below the quenching bracket; a submersible pump is arranged in the water receiving tank; the cooling water tank is mounted in the quenching liquid water tank; and a backflow copper pipe is mounted in a quenching liquid cooling work cavity below the cooling water tank. In the invention, induction quenching heating of a workpiece is realized through the induction coil heating device, the sliding component can perform sliding switch of the workpiece between two step positions of induction heating and quenching cooling, and the operation is more convenient and quicker; and moreover, high-temperature quenching liquid and high-temperature cooling water can be subjected to cooling heat exchange treatment at the same time, a refrigeration industrial air conditioner and a set of cooling system are shared, and therefore, the equipment is compact in structure and convenient to mount on a production line.

Description

technical field [0001] The invention relates to the technical field of quenching of workpieces or parts, in particular to a quenching system and method applied to induction quenching of workpieces. Background technique [0002] Induction heating is the most commonly used surface heating and quenching method. It has the advantages of simple process, small distortion of heated workpieces, high production efficiency, energy saving, less environmental pollution, and easy mechanization and automation of the process. The surface hardening layer is obtained after the workpiece is heated and quenched on the surface, and the core of the part can still maintain the original microstructure and performance, thereby improving the fatigue strength and wear resistance and maintaining the excellent comprehensive performance of the core toughness. [0003] The function of the keyway is to connect the hole parts and the shaft parts so that the torque can be transmitted between them. Therefore...

Problems solved by technology

However, the main part of this type of machine tool and the water circulation system occupy a large area, which is not conducive to on-site installation

At the same time, the heating effect of keyway and other products that require external heating is not good, and special tooling needs to be made for positioning, responsible operation, high energy consumption, uneven hardness and depth of the hardened layer of the product, etc.
