Description

Technical Field

[0002] The punching machine is a mechanical equipment that completes the punching by applying a punching die to the material after the raw materials are installed and driven by a power mechanism. The punching machine can perform operations such as sheet processing, stamping, molding, embossing, etc. to force metal into the die. Existing guardrails and railings need to be processed and installed on metal pipes during production. When the existing device is in use, if a longer square pipe is to be punched, the staff needs to clamp one end of the square pipe with a clamping device and then hold the other end with their hands to stabilize it, which increases the labor intensity of the staff. There is an existing square pipe punching machine CN220028389U, which includes a punching machine body, which includes a workbench and a punch. Both sides of the top of the workbench are fixedly connected with electric slide rails, and the inner wall of the electric slide rails is slidably connected with an electric slider, and the tops of the two electric sliders are provided with clamping mechanisms. In the present application, when in use, the square tube is sleeved on the mobile rack, and the sleeve is squeezed against the inner wall of the mobile rack, and then the position of the square tube is adjusted, the position of the square tube to be punched is aligned with the bottom of the punch, and the threaded rod is rotated. The rotation of the threaded rod can make the clamp clamp the square tube, and finally the punching operation can be performed. When the square tube is moved, the electric slide rail can be started. At this time, the electric slider slides in the inner wall of the electric slide rail, so that the square tube can be moved on the mobile rack. Therefore, it can avoid that the staff always hold the square tube by hand, and the labor intensity of the staff is reduced.
