Abstract

The invention discloses a punching die for a shield, and relates to the technical field of punching die manufacturing. The punching die for the shield comprises an upper die base and a lower die base; the lower end of the upper die base is provided with a punch holder and a first punch; a discharging plate sleeves the lower part of the first punch; a discharging spring is arranged between the discharging plate and the punch holder; the upper end of the lower die base is provided with a workpiece locating block and two supporting shoes; a sliding plate penetrates through each supporting shoe; each sliding plate is provided with a second punch extending to the workpiece locating block; the upper part of each sliding plate is provided with a limiting boss; a reset spring is arranged between each limiting boss and the corresponding supporting shoe; the outer side of each supporting shoe is provided with a baffle; a stamping block of which the upper end is fixedly connected with the upper die base is arranged between each baffle and the corresponding supporting shoe; the outer side of each stamping block is abutted against the corresponding baffle; the inner side of each stamping block is provided with an oblique plane in compression joint with the corresponding limiting boss. Compared with the prior art, the punching die disclosed by the invention has the characteristics that the shield is arranged on the workpiece locating block, punching processing is performed on the shield by the first punch and the second punches simultaneously, the shield can be easily clamped, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of stamping die manufacturing, in particular to a punching die used for a protective cover. Background technique [0002] Such as figure 1 The protective cover shown has a cylinder and a cone connected to the upper end of the cylinder. The upper end of the cone is provided with a cover plate, and a mounting hole is provided on the cover plate. Two limit holes are provided on the wall of the cone cylinder. . Since there is no special punching die for the protective cover, it is difficult to process the installation hole and the limit hole of the protective cover, and the production efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a protective cover punching die to solve the problems of difficulty in mounting and clamping the mounting holes and limit holes of the protective cover and low production efficiency. [0004] In order...
