Abstract

The invention discloses a punching jig. The punching jig comprises a base, a backing plate, a fixing plate, a male die, a stripper plate, a female die, a punching plate and a punching head handle, wherein the backing plate is fixed to the upper portion of the base, the fixing plate is arranged on the upper portion of the backing plate, the male die is arranged in the center of the fixing plate and penetrates through the stripper plate, the stripper plate is connected with the fixing plate in a spaced mode through stripper bolts, the female die is arranged in the center of the punching plate, the punching head handle is fixed to the upper portion of the female die, and the base, the backing plate, the fixing plate, the stripper plate and the male die share the same axis and are fixed through a positioning screw. In this way, through the inverted structure, the punching direction and position accuracy can be guaranteed easily, and the boundary dimension and punching position of a punched part will not be limited by the dies; the stripper plate in a lower die can be used for stripping and can also support a blank, and therefore operation is facilitated.

Description

technical field [0001] The invention relates to a jig, in particular to a punching jig. Background technique [0002] Punching is a commonly used processing technology in the industrial field, which refers to punching various graphics on steel plates, leather, cloth, wood and other materials to meet different processing needs. For the local filling of large parts, the precision and shape of the punching are easily restricted by the mold during punching, and the waste in the mold is difficult to remove, which affects the overall quality of the large part. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a punching jig, which is beneficial to ensure the punching direction and position accuracy through the flip-chip structure. The unloading plate can not only unload the material, but also hold the blank, which is convenient for operation. [0004] In order to solve the above technical problems, a technical sol...
