Abstract

The invention belongs to the technical field of sealing strip processing, and specifically discloses a film continuous punching tool and its punching process, including a frame, on which a punching mechanism and a transmission mechanism are arranged, and the transmission mechanism is used to transmit the film to be punched. The film, the punching mechanism is located above the transmission mechanism, the punching mechanism includes a rotating cylinder connected to the frame, the outer wall of the rotating cylinder is evenly distributed with multiple groups of punching components along the circumference, the punching components include punching parts and shearing parts, punching The hole piece includes a punching nail detachably connected to the outer wall of the drum. The punching nail includes a mounting part for connecting with the drum and a punching part for punching holes. The punching part is in the shape of a ring; the shearing part includes The connecting part for connecting with the outer wall of the drum and the shearing part for cutting the film, the length direction of the connecting part is parallel to the axial direction of the drum, and the shearing part includes several triangular prism-shaped shears distributed along the length direction of the connecting part. Cutting blocks, with spacing between adjacent cutting blocks. By adopting the scheme of the invention, the problem of continuous punching of the film can be solved.

Description

technical field

[0001] The invention belongs to the technical field of sealing strip processing, and in particular relates to a film continuous punching tool and a punching process thereof. Background technique

[0002] At present, the two ends of the sealing strip (car door frame products) need to be connected after the processing is completed, so that the sealing strip forms a ring shape. In order to obtain a better docking effect, a film is usually set at the joint of the sealing strip, and the film is vulcanized Fix with the end of the sealing strip. Because most of the sealing strips are bubble tube products, it is easy to deform when the car door is opened and closed. In order to avoid gas blockage when the sealing strip is deformed, it is necessary to open a through hole on the film that communicates with the inner cavity of the sealing strip.

[0003] In the prior art, punching holes on the film is usually done manually by directly pressing the film through a circul...
