Description

Blanking, drawing, punching and punching composite mold for electric switch net core

technical field

The utility model relates to a mechanical processing mould, in particular to a blanking, drawing, punching and punching composite mould, which is used for processing electrical switch net cores. the

Background technique

Electrical switch mesh cores are usually punched by molds, and two sets of molds are often used to complete the process twice. One set of molds is a composite die for blanking and deep drawing, and the other set is used for punching. In order to prevent the hole from being deformed, the blanking and deep drawing are carried out first, and finally the hole is punched. The blanking and deep drawing compound mold, the concave-convex mold fixing plate of the upper mold base is fixed to the concave-convex mold vertically downward; the convex mold fixing plate is fixed on the lower mold base, and it is fixed. The die matching the concave and convex dies is fixed with screws. When working, driven by the power mechanism, the upper mold base moves up and down through the guide column and guide sleeve structure arranged between the lower mold base and blanks and draws the sheet metal passing through the mold horizontally. Another pair of punching dies, the punch fixing plate of the upper die base fixes the punch, the lower die base fixes the die matching the punch, and the completed blanking and drawing parts are placed on the die manually , complete a punching. the

The disadvantages of the above-mentioned molds are: two pairs of molds are used to complete the stamping of a workpiece, the number of molds is large, and the stamping equipment is also occupied, and the productivity is low. One punch should be high. the
