Description

Technical Field

[0001] The utility model relates to the technical field of production of automobile backrest mounting fixing plates, in particular to a punching machine for producing automobile backrest mounting fixing plates. Background Art

[0002] The car backrest is the supporting part between the seats and is also an important part for passengers to sleep and rest. The main function of the car backrest is to provide a comfortable resting environment for the passengers. When installing the car backrest, there is usually a special fixing plate to assist the installation of the car backrest. When producing the car backrest fixing plate, it is usually necessary to use a punch press with the corresponding mold to stamp the car backrest fixing plate.

[0003] At present, when the automobile backrest mounting fixing plate is produced between the punching machine and the matching mold, when the residual waste is punched out of the plate of the fixing plate, a small amount of residual waste will remain on the bottom mold surface of the punching machine. For this residual waste, workers usually hold a dust blow gun connected to an air source for manual blowing. However, the operation of workers holding a dust blow gun and continuously blowing the fixed plate mold for a long time is relatively boring, which causes some workers to easily forget to blow the mold, resulting in residual material mis-pressing lines when the fixed plate is stamped, affecting the stamping quality of the automobile backrest fixing plate. For this reason, we propose a punching machine for producing automobile backrest mounting fixing plates. Utility Model Content
