[0002] A flange, also called a flange plate or flange, is a part used to connect pipes to each other, and is used to connect the pipe ends; flanges are also used on the inlet and outlet of equipment to connect two pieces of equipment, such as a speed reducer flange.
[0003] When processing flanges, punching is required at the corresponding positions. Punching is often done manually by tightening the screws. This fixing method is not secure and can easily cause the flange to fly out during forging and punching, resulting in processing accidents. Furthermore, the flange position is fixed during punching, and the punching part moves vertically, so punching can only be done at a single position and the flange needs to be constantly adjusted before punching again, resulting in low punching flexibility. Utility Model Content
