metal stamping parts are used in different fields, and their demand and demand are also getting higher and higher. with the development trend of science and technology, most of the sheet metal parts processing manufacturers have also completed automatic production. During the entire stamping process, overheating may occur, which can lead to common failures. The text examines the potential hazards that may arise after common faults are triggered by overheating.

1. according to the plastic deformation characteristics of professional sheet metal processing customized metal materials, heat generation in the whole blanking process will cause temperature rise. When the convex and concave dies continue to work under continuous high temperature, the softened raw materials to be produced will stick to the side of the die base and continue to expand, and will only fall off when a ji special offer is achieved. The continuous circulation system will cause the condition of gnawing the mold and accelerate the damage of the mold.

2. cause the side working pressure and continuous high temperature swelling to change the mold gap between the concave and convex molds, resulting in sudden changes in the wound appearance or large triangular burrs, or occurrence of mold gnawing.

3. when carrying out rapid and continuous blanking for metal stamping parts raw materials with large calorific value, low thermal conductivity and large linear expansion coefficient, such as stainless steel plates, if only to avoid heating, refrigeration method can be adopted; if the sheet metal manufacturing co., ltd. causes "shrinkage" during blanking, if the products in the mold are not quickly disposed of, continuous rapid blanking cannot be realized. Liquid lubrication method can be applied, according to the solution to carry out cleaning, refrigeration, lubrication or blowing air compression method.
