Heat treatment quenching device for high chrome alloy wear-resistant steel forging

Abstract

The invention discloses a heat treatment quenching device for a high chrome alloy wear-resistant steel forging, and belongs to the field of quenching. The heat treatment quenching device comprises a base, wherein a quenching box is fixedly arranged at one side of the upper end face of the base; a stirring shaft is fixedly arranged at the two sides of the lower end in the quenching box through bearings; the side face of the stirring shaft is located in a cavity arranged in one side in the quenching box; a motor is fixedly arranged on the side face of the cavity; the shaft end of the motor is fixedly arranged at the end of the stirring shaft; a sealing block is fixedly arranged on the side face of the cavity and located on the periphery of the stirring shaft; the sealing block is rotationally connected to the side face of the stirring shaft in a sleeving mode; a filter screen is slidably connected to the inner side face of the quenching box; and connecting plates are fixedly arranged at the two sides of the upper end face of the filter screen. According to the heat treatment quenching device for the high chrome alloy wear-resistant steel forging, the stirring shaft can be driven to rotate through the motor, so that when materials are quenched, quenching oil flows on the surfaces of the materials, workpieces can be sufficiently quenched, and the quenching effect is improved.

Description

technical field [0001] The invention relates to the field of quenching devices, in particular to a heat treatment quenching device for high chromium alloy wear-resistant steel forging. Background technique [0002] The purpose of quenching is to transform supercooled austenite into martensite or bainite, and obtain martensite or bainite structure to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel, so as to meet the Different use requirements for various mechanical parts and tools. [0003] When the traditional quenching device quenches the material, it usually quenches the material by spraying. The workpiece causes insufficient quenching, the quenching speed is slow, and the quenching effect is poor. Moreover, there is no filtering device on the traditional quenching device, and the debris generated by quenching Or impurities cannot be separated from the quenching oil, and the filtering effect is poor. The quenching oil is us...

[0003] When the traditional quenching device quenches the material, it usually quenches the material by spraying. The workpiece causes insufficient quenching, the quenching speed is slow, and the quenching effect is poor. Moreover, there is no filtering device on the traditional quenching device, and the debris generated by quenching Or the impurities cannot be separated from the quenching oil, and the filtering effect is poor. In the traditional quenching device, the quenching oil is usually sprayed directly on the surface of the workpiece during quenching, which cannot be recycled, and the use effect is poor.
