Abstract

The invention discloses a perforating die for a door guide rail. The perforating die mainly comprises a lower die body, a fixed backer, a movable backer, an upper die body, guide posts, guide holes, punching heads, a left limiting boss and a right limiting boss. The fixed backer and the movable backer are mounted on the top face of the lower die body and close to the left side face. The movable backer is located on the right side of the fixed backer. The three sets of guide holes are formed in the lower die body. Each set of guide holes comprises two guide holes. The left limiting boss and the right limiting boss are fixedly mounted on the top face of the lower die body. The three sets of guide posts are arranged on the bottom face of the upper die body. Each set of guide posts comprises two guide posts. The guide posts on the upper die body are located over the guide holes in the lower die body. The four punching heads are mounted on the bottom face of the upper die body.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a door guide rail punching die. Background technique [0002] At present, the mounting holes of the door guide rails are single punched by a punching machine, which has low processing efficiency, increases the cost of the enterprise, has high labor intensity, and has great potential safety hazards, especially the processing effect is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a door guide rail punching die with a simple structure and low cost, which improves work efficiency and eliminates the hidden danger of missed punching through integral punching by a bending machine. [0004] The technical solution adopted by the present invention to solve the technical problem is: a door guide rail punching die, including a lower die, a fixed backer, a movable backer, an upper die, a guide column, a guide hole, ...
