Inverse punching and blanking die

Abstract

The invention relates to an inverse punching and blanking die and relates to a stamping die. The inverse punching and blanking die comprises an upper die base, a lower die base, a die handle, a guide sleeve and a guide post, wherein a male and female die is arranged on the upper surface of the lower die base; a punching profile hole is formed in the male and female die; an unloading plate is sleeved on the male and female die and is moveably connected with the lower die base through an unloading screw; a rubber cushion is arranged between the unloading plate and the lower die base; a blanking female die is arranged on the lower surface of the upper die base; a female die hole is formed in the lower surface of the blanking female die; the position of the female die hole corresponds to the male and female die; a punching male die matched with the punching profile hole is arranged in the female die hole; a workpiece jacking device is arranged on the punching male die. Blanking and punching of a workpiece can be finished in one set of die, so that the production efficiency is improved, the workpiece is prevented from being repeatedly positioned, and the product precision is improved.

Description

technical field

[0001] The invention relates to a stamping die, in particular to a flip-chip punching blanking die. Background technique

[0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a material at room temperature to cause separation or plastic deformation to obtain the required parts. Stamping die is an essential process equipment for stamping production, and it is a technology-intensive product, which can perform forming processes such as punching, blanking, bending and deep drawing. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. In the stamping process, it is often necessary to punch the material strip after blanking. To use the existing mold, the workpiece needs to be blanked in the blanking mold first, and then put into the punching mold to punch holes. In this way, there are many processes and low production efficiency. ...
