[0002] Anti-loosening washers are also known as anti-loosening washers, self-locking washers, self-locking washers, double-stack self-locking anti-loosening washers, etc. Traditional washers are single-piece washers that work independently. This type of washer mainly relies on friction to achieve the anti-loosening effect. The new type of washer is composed of two pieces. Its unique embedded structure changes the traditional washers that mainly rely on friction to achieve anti-loosening. Instead, it adopts the most advanced anti-loosening technology in the world and uses the tension between the two washers to achieve the dual effects of anti-loosening and tightening. Anti-loosening washers are mainly processed by stamping.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN212190846U discloses a molding device for anti-loosening washers, including a workbench, the top of the workbench is fixedly connected with a mold, the top of the mold is provided with a molding groove, the bottom of the inner cavity of the molding groove is provided with a third groove, the bottom of the inner cavity of the third groove is provided with a second mounting groove, the top of the workbench is fixedly connected with support rods all around, the top of the support rod is fixedly connected with a top plate, the left and right ends of the bottom of the top plate are rotatably connected with threaded pipes through bearings, the outer surface of the threaded pipe is sleeved with a first belt pulley, and the inner cavity of the threaded pipe is threadedly connected with a threaded rod. The utility model solves the problem that the punching head of the current anti-loosening washer stamping molding device is fixed with screws, which is inconvenient for people to replace the punching head, through the cooperation of the molding groove, the electromagnet, the jack, the first groove, the second groove, the iron block, the electric telescopic rod, the connecting plate, the plug block, the third groove and the push plate.

[0004] The forming device of the anti-loosening gasket fixes the punch head through the magnetic force of the electromagnet during use, which facilitates the replacement of the punch head.
