Quenching device for mechanical shaft parts

Abstract

The invention relates to the technical field of metal processing, in particular to a mechanical shaft part quenching device. The mechanical shaft part quenching device comprises a water tank, a workpiece base, high-frequency quenching machines, high-frequency copper coils and a controller, wherein the controller is used for working of the part quenching device, the top of the water tank is opened,and the upper end of the water tank is fixedly provided with the workpiece base; and the workpiece base covers half of the opening of the water tank, the three high-frequency quenching machines are fixedly installed on the upper side surface of the workpiece base, and the diameters of the high-frequency copper coils installed on the high-frequency quenching machines are different. According to the mechanical shaft part quenching device, shaft parts extend into the high-frequency red copper coils for high speed heating by pushing a clamping assembly upwards through an air cylinder, after the temperature rising is completed, the air cylinder is contracted, the shaft parts are put into water for quenching, and the quenching processing for the shaft parts with different diameters can be achieved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a quenching device for mechanical shaft parts. Background technique [0002] The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness and wear resistance of the steel. properties, fatigue strength and toughness, etc., so as to meet the different requirements of various mechanical parts and tools. Quenching can also be used to meet the special physical and chemical properties of some special steel materials such as ferromagnetism and corrosion resistance. [0003] At present, metal shaft parts need high-frequency quenching after processing to improve mechanical properties. Generally, the high-frequency quenching is to directly place the shaft in the high-frequency quenching coil, and the quenchin...

AI Technical Summary

Problems solved by technology

[0003] At present, metal shaft parts need high-frequency quenching after processing to improve mechanical properties. In high-frequency quenching, the shaft is generally placed directly in the high-frequency quenching coil, and the quenching is completed when the coil is connected. However, the existing shafts The specifications and diameters of the parts are various. The existing quenching device can only quench the shaft parts of one diameter in general, which has great limitations. Therefore, a kind of quenching device that can quench the shaft parts of different diameters is proposed. Quenching device for mechanical shaft parts
