Transverse die forging machine manufacturers tell you that punching refers to a punching method that uses a die to separate the sheet from the blank with a closed outline. Die refers to the processing method of process equipment for separating, forming or joining precision forged metal, non-metallic sheet or profile by avoiding pressure. Dropping and punching are both punching processes. Blanking refers to punching along the closed contour curve with die stamping, the punched part is the part, and the surrounding is scrap; punching refers to separating the material in the stamping blank with a closed contour to obtain a perforated part. In the stamping method, the part that is punched out is scrap, and the hole formed in the periphery is the finished product.

Transverse die forging machine manufacturers tell you the blanking process of precision forging sheets. Both punch and die have sharp edges, and there is a certain gap between them. When the punch (punch) contacts the sheet and continues to press down, the sheet is squeezed, which first makes the sheet elastically deformed, and when the tensile stress value in the sheet reaches the yield point, plastic deformation occurs; Transverse die forging machine manufacturer It tells you that when the deformation reaches a certain level, the sheet metal located at the edge of the convex and concave die will start to generate micro-cracks along the edge of the convex and concave die due to the strengthening of cold deformation and stress concentration; when the upper and lower cracks expand, the sheet will be broken, complete separation process.
The influence of the casting mold on the fluidity during precision forging is mainly manifested in the resistance and thermal conductivity of the casting mold. All factors that can increase the flow resistance of gold and increase the cooling rate in the mold reduce the fluidity. Transverse die forging machine manufacturers tell you that such as small runner cross section, rough cavity surface and poor air permeability will increase the flow resistance of the molten metal, reduce the flow rate, and thus reduce the fluidity of the molten metal. The casting guide is strong. The faster the heat dissipation of the liquid, the worse the fluidity.
