Processing method for refrigerator bottom plate stamping part

Abstract

The invention discloses a processing method for a refrigerator bottom plate stamping part. The processing method comprises the following steps: after heating a steel billet, rolling the steel billet to form a steel plate, carrying out heat treatment on the steel plate, and finally, cooling the steel plate to the room temperature; carrying out deep stamping formation on the steel plate by using a stamping die to preliminarily prepare the geometrical shape and size of the required refrigerator bottom plate stamping part; carrying out edge cutting, edge folding, punching and bending on the steel plate, pressing the treated steel plate into a die to stamp, then, taking out the steel plate, and bending and indenting the steel plate; and finally, carrying out surface finishing, checking the quality after completing the treatment, and leaving the product from a factory if the quality is qualified. The processing method for the refrigerator bottom plate stamping part, disclosed by the invention has the advantages of simple processing procedures, simplicity in operation, high production and processing efficiencies, high finished product rate and low processing cost so as to be suitable for industrial production. The refrigerator bottom plate stamping part prepared by using the processing method has the characteristics of light and thin material, high strength, good rigidity, smooth surface and high size precision so as to be worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of refrigerator spare parts processing, in particular to a method for processing stamped parts of a refrigerator bottom plate. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20-500 liters. In 1910, the world's first household refrigerator with compression refrigeration came out in the United States; in 1925, Lido Company of Sweden developed a household absorption refrigerator; in 1927, General Electric Company of the United States developed a fully enclosed refrigerator; The air-cooled continuous diffusion absorption refrigerator was put on the market; the new refri...
