Problems solved by technology

Due to the need for contact between the sheet material and the forming flanging mold during the forming flanging process, heating or extrusion increases the friction between the sheet material and the forming flanging mold, resulting in loss of the sheet material after forming the flanging
[0004] In actual production, the material of the forming and flanging mold used in the factory is usually GCr15 steel, which has excellent wear resistance and suitable hardness, but its resistance is average, so after long-term forming and flanging operations, the forming The flanging mold will be deformed due to the influence of extrusion or heating, which will cause the forming size of the sheet to exceed the error range, the rework rate will be high, and the efficiency will be low. Moreover, the deformation of the mold and the frictional resistance between the mold and the sheet will cause It makes it difficult to demould the formed sheet, and even cause the mold to jam, which in turn affects the production efficiency of auto parts
