Problems solved by technology

If high section quality is required, it is necessary to use CNC machine tools to machine the working end face of stamping products to obtain stamping products with high-precision section quality. However, CNC machine tools are also expensive, not only the manufacturing cost is high, but also can only be processed in a single piece , unable to realize automated mass production, low production efficiency, and unable to meet the needs of high production capacity of the factory

Embodiment Construction

[0014] See also Figure 2 to Figure 4 , The stamping die 200 includes an upper die 21 and a lower die 22 . The upper mold 21 has a working surface 211 . The upper mold 21 shapes the section of the workpiece 31 through the working surface 211 . The lower mold 22 has an operating surface 221 and a side 223 vertically connected to the operating surface 221 . The workpiece 31 is fixed on the operation surface 221 and kept fixed with the lower mold 22 . The stamping gap between the upper die 21 and the lower die 22 is zero, that is, the vertical distance between the working surface 211 of the upper die 21 and the side 223 of the lower die 22 is zero, and the working face 211 and the side 223 are on the same plane.

[0015] During the stamping process, the workpiece 31 is fixed on the operation surface 221 of the lower die 22 and partially protrudes from the operation surface 221 toward the side surface 223 . When the upper die 21 moves in the direction of arrow A, the workpiece...

Abstract

A punching die is used for processing a workpiece into a punching product with the section bright area reaching more than 90 percent. The punching die comprises an upper mold and a lower mold; the punching clearance between the upper mold and the lower mold is smaller than one two hundredth of the thickness of the workpiece. A punching shaping method includes the following steps: (1) a low mold is provided and the workpiece is arranged at the lower mold; (2) an upper die is provided and the punching clearance between the upper mold and the lower mold is smaller than one two hundredth of the thickness of the workpiece. The upper mold and the lower mold are matched to carry out punching on the section of the workpiece so as to form the punching product.

Description

technical field [0001] The present invention relates to a stamping die, in particular to a stamping die for forming stamped products with high-precision section quality. The present invention also relates to a stamping method for forming a stamped product with high-precision cross-sectional quality and a product formed by the stamping method. Background technique [0002] The cross-sectional quality of stamped products formed by ordinary stamping dies for stamping materials is generally poor. Such as figure 1 As shown, the section of a stamped product 10 formed by an ordinary stamping die is generally composed of four parts: sagging angle 11, bright band 12, tear band 13 and burr 14, wherein the number of bright bands 12 determines the cross-sectional quality of the stamped product good or bad. Furthermore, the quality of the cross section of the stamping product also affects its appearance to a certain extent. [0003] With the development of society, more and more stam...
