Household appliance stamping production process

Abstract

The invention discloses a household appliance stamping production process. The process comprises the following steps that S1, preparing work is carried out; S2, a heat conduction cover is arranged outside an upper mold and a lower mold of a forming mold, and a circulation condensation pipe is arranged outside the heat conduction cover; S3, a lubricant coats the inner surfaces of the upper mold andthe lower mold of the forming mold; S4, materials are injected, the upper mold and the lower mold are closed, pressure maintaining and blanking procedures are carried out, demolding is completed, thenumber of times of the blanking procedures is recorded, when the number of times reaches the limit, the forming and blanking procedures are stopped, a heat conduction cover switch is started, coolingis carried out, after cooling is completed, the forming and blanking procedures are started again, and the record of the number of times of the blanking procedures is reset to be 0; and S5, the subsequent stamping procedure is carried out until the material is conveyed to a discharging area, and the stamping production process is completed. According to the household appliance stamping productionprocess, the heat dissipation is fast in the production process, the abrasion of the mold is small, and the service life of instrument equipment is long; and the product production and instrument usecost is low, the product reproducibility is good, and the percent of pass and the production efficiency are high.

Description

technical field [0001] The invention relates to the technical field of home appliance production, in particular to a home appliance stamping production process. Background technique [0002] Stamping processing is the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force and deformed in the mold, so as to obtain product parts with a certain shape, size and performance. It is the most commonly used forming in the production of home appliances. It mainly includes forming, blanking, bending, shearing, stretching, bulging, spinning and correcting processes. Among them, the forming process is the premise and basis of other processes in stamping production, so the forming process is of great significance to stamping production. However, as the sales of home appliances increase year by year, the production pressure of the stamping production line is increasing. In order to reduce production costs, each process is us...

Problems solved by technology

However, as the sales of home appliances increase year by year, the production pressure of the stamping production line is increasing. In order to reduce production costs, each process is usually placed at the highest load, which also leads to an increase in the frequency of problems in the forming process. For example, the inner surface of the stamping die wears a lot, and the maintenance is not timely, resulting in the molded product not meeting the standard, and even causing the die to be jammed or damaged; the heat generated during the forming process is relatively large, and the heat dissipation rate of the existing production process is relatively slow. Slow and so on
