Description

Technical Field

[0001] The utility model relates to the technical field of door and window fitting processing doors, in particular to a hole punching device for door and window sealing strips. Background Art

[0002] In daily life, gaps in doors and windows are common, which greatly reduces the sealing performance of doors and windows and cannot meet the use in daily life. Therefore, door and window sealing strips are needed to block these gaps and increase the sealing performance of doors and windows. Therefore, threaded holes for installing sealing strips will be added to doors and windows during the production process, so corresponding through holes need to be opened on the sealing strips to facilitate the installation of the sealing strips.

[0003] However, in today's factories, sealing strips are produced on an assembly line basis. The sealing strips are sent to the punching equipment through a conveying device for punching. However, due to the production mode problem, the conveying device does not stop during the punching process of the sealing strips. This causes the sealing strips to break during the punching process. This requires workers to pause the production line, repair the broken parts and then continue production. This not only reduces the factory's production efficiency, but also increases the factory's production costs. Utility Model Content

The slider 15 is fixedly connected to the top plate. The slide rail 14 and the slide rail 14 can make the movement of the bottom plate 301 more stable.

[0029] An empty slot 16 is provided on the bottom plate 301 , and the empty slot 16 is located at the exit of the limiting slot 5 . A collecting box 17 is provided below the empty slot 16 , and the collecting box 17 is placed on the ground. The punched waste of the sealing strip falls from the empty slot 16 into the collecting box 17 .

[0030] Working principle of the utility model: the transport device 1 transports the sealing strip to the limit block 302 and passes it through the limit groove 5. The limit groove 5 performs a preliminary limit on the sealing strip. At the same time, the cylinder 305 on the concave bracket 304 drives the punching head 306 to extend from the through groove 4 into the limit groove 5 to punch holes in the sealing strip in the limit groove 5. Since the transport device 1 will not stop, when the punching head 306 punches holes in the sealing strip, it will drive the bottom plate 301 to move under the action of the force, thereby pulling the tension spring 307 to make it move at the same time as the sealing strip. When the cylinder 305 contracts, the bottom plate 301 will rebound quickly under the action of the tension spring 307 to repeat the cycle.
