Embodiment 1

[0010] A method for processing an electrical cabinet body, which includes the following processing steps for the electrical cabinet body:

[0011] 1) Quenching: put the main body of the electrical cabinet separately or as a whole into the quenching liquid for quenching, and the mass percentage of the quenching liquid is 20%;

[0012] 2) Heating: put the above quenched and tempered electrical cabinet body separately or in whole into the heating furnace, heat it to 800°C for the first time, and keep it for 2 hours; heat it again to 850°C, and keep it for 2 hours; finally add Warm to 900°C, place to cool;

[0013] 3) Tempering: After the above-mentioned workpiece is cooled to 500°C, send the processed piece to the tempering furnace, and cool the air to 200°C. At this time, temper the processed piece to 500°C and keep it warm for 2 hours.

Embodiment 2

[0015] A method for processing an electrical cabinet body, which includes the following processing steps for the electrical cabinet body:

[0016] 1) Quenching: put the main body of the electrical cabinet separately or as a whole into the quenching liquid for quenching, and the mass percentage of the quenching liquid is 23%;

[0017] 2) Heating: Put the above quenched and tempered electrical cabinet body separately or in whole into the heating furnace, heat it to 820°C for the first time, and keep it for 3 hours; heat it again to 860°C, and keep it for 3 hours; finally add Temperature to 950°C, place to cool;

[0018] 3) Tempering: After the above processed parts are cooled to 530°C, send the processed parts to the tempering furnace, and cool the air to 230°C, then temper the processed parts to 530°C for 3 hours.

Embodiment 3

[0020] A method for processing an electrical cabinet body, which includes the following processing steps for the electrical cabinet body:

[0021] 1) Quenching: put the main body of the electrical cabinet separately or as a whole into the quenching liquid for quenching, and the mass percentage of the quenching liquid is 25%;

[0022] 2) Heating: put the above quenched and tempered electrical cabinet body separately or in whole into the heating furnace, heat it to 830°C for the first time, and keep it for 4 hours; heat it again to 880°C, and keep it for 4 hours; finally add Warm to 1000°C, place to cool;

[0023] 3) Tempering: After the above-mentioned workpiece is cooled to 550°C, send the processed piece to the tempering furnace, and cool the air to 250°C. At this time, temper the processed piece to 550°C and keep it warm for 4 hours.

Abstract

The invention relates to a machining method for an electrical cabinet body. The machining method for the electrical cabinet body comprises the following steps that (1) the electrical cabinet body is quenched, specifically, the electrical cabinet body is separately or integrally placed in quenching liquid to be quenched, and the mass percent of the quenching liquid is 20%-25%; (2) the electrical cabinet body is heated, specifically, after being quenched and tempered, the electrical cabinet body is separately or integrally placed in a heating furnace to be heated to the temperature of 800-830 DEG C for the first time, and heat preservation is conducted for 2-4 hours; then the electric cabinet body is heated to the temperature of 850-880 DEG C, and heat preservation is conducted for 2-4 hours; and finally, the electrical cabinet body is heated to the temperature of 900-1000 DEG C and stands to be cooled; and (3) the electrical cabinet body is tempered, specifically, after being cooled to the temperature of 500-550 DEG C, the electrical cabinet body is conveyed into a tempering furnace and air-cooled to the temperature of 200-250 DEG C, the electrical cabinet body is tempered to the temperature of 500-550 DEG C at the moment, and heat preservation is conducted for 2-4 hours. According to the machining method for the electrical cabinet body, operation is easy, cleanliness is guaranteed, smoke and odor are avoided, ignition is avoided, and the good structure and performance can be obtained after quenching and tempering; and practice indicates that after quenching in PQL water-based quenching media and tempering, the hardness uniformity, red hardness and service life of a mold are better compared with the hardness uniformity, red hardness and service life of a mold subjected to quenching through quenching oil.

Description

technical field [0001] The invention relates to a method for processing an electric cabinet body. Background technique [0002] In the mold strengthening process, heat treatment is generally used, but the traditional oil quenching medium is easy to cause fire, which brings hidden dangers to safe production. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for processing an electrical cabinet body with simple processing, smoke-free and environment-friendly, good strength and uniform hardness. [0004] The technical scheme of the present invention is: it comprises electrical cabinet body and carries out following processing steps: [0005] 1) Quenching: put the main body of the electrical cabinet into the quenching liquid or the whole body for quenching, and the mass percentage of the quenching liquid is 20-25%; [0006] 2) Heating: Put the above quenched and tempered electric cabinet body separately or in who...
