[0002] Punching is one of the most important deformation processes in the production of hot-rolled seamless steel pipes. Therefore, a punching machine is usually used to perform hydraulic drawing and forming on the seamless steel pipe. When punching the seamless steel pipe, a blanking component is usually required to be added to the blanking end of the punching machine to conveniently load the seamless steel pipe raw materials. As shown in a punching machine for seamless steel pipe processing disclosed on the China Patent Network (public announcement number CN221621577U), this type of punching machine uses a feeding device in the form of a conveyor wheel when it is in operation.

By controlling the operation of the brake motor 3, the traction pulley 11 is driven to rotate. By utilizing the traction pulleys 11 arranged on both sides of the brake motor 3 body, the traction pulley 11 is used to tension and traction the transmission belt 4, and the transfer rotation of the transmission belt 4 drives the transmission pulley 10 to rotate, and then drives the transmission screw 8 to rotate. As a power source, it pushes the relative conveying and loading mechanism 6 to move in opposite directions to adapt to the support work of steel pipe materials of different sizes.

The transmission screw 8 is bounded by the center line, and the two sides of the center line are symmetrically provided with positive and negative threads adapted to the two groups of transmission slides 9.
