Stamping die with high flatness

Abstract

The invention discloses a stamping die with high flatness. The stamping die comprises a male die and a female die which are matched with each other, the female die is provided with a through hole which is the same as the shape of a product, a support plate is slidably connected in the through hole, the upper surface of the support plate is horizontally arranged, a base is arranged below the femaledie, a plurality of support columns are arranged between the base and the female die, a connecting shaft is vertically arranged on one side, close to the base, of the support plate, the connecting shaft is slidably connected in the base, the length of the support columns is greater than the thickness of the support plate, and the lower surface of the male die is provided with a convex block matched with the through hole. The stamping die has the effect of improving the perpendicularity of the side surface at the edge of the product.

Description

technical field [0001] The invention relates to the field of stamping dies, more specifically, it relates to a stamping die with high flatness. Background technique [0002] The stamping die is mainly used on the stamping machine to stamp the plate, and mainly produces the required complex hardware and metal plates in electronic products. The stamping die is a complete set, including a punch and a die that cooperate with each other. The sheet is placed between the punch and the die. When the punch and the die are closed, the shear force is used to divide the product of a specific shape on the sheet. . [0003] Such as Figure 7 As shown, a stamping die includes a punch 1 and a die 2 arranged up and down, a bump 3 with the same shape as the product is set on the lower surface of the punch 1, and a through hole with the same shape as the product is opened on the die 2 twenty one. The plate is placed between the punch 1 and the die 2, and when the molds are closed, the bump ...

AI Technical Summary

Problems solved by technology

However, for the steel strip 7, there is a certain range of variation in the shear resistance of each point of the steel strip 7, so that when the steel strip 7 is punched and sheared, the outline of the product on the steel strip 7 is not simultaneously drawn. There is a slight time difference in shearing, which causes the side of the product to be inclined instead of vertical, so the precision of the stamped product is usually lower than that of the chip, which makes the stamping process fast, but loses precision
