The main function of the pressing unit is to compress the angle steel to be printed, punched, and sheared to prevent the angle steel from deviating when it is stressed and affect the processing accuracy, and it is also a mechanism to overcome the punching and shearing force.

Punching unit: It consists of three bodies fixed on the machine base, two sets of hydraulic cylinders, two sets of die holders with molds, two sets of driving mechanisms, and two sets of servo units for adjusting the pitch. Each side of the unit can be equipped with two different specifications of punches, each punch is equipped with a cylinder. A cushion block is connected to the cylinder piston rod, and the cushion block is installed between the punch rod and the cylinder pressure head. According to computer instructions, the punch is automatically selected, that is, the corresponding cylinder is selected to push the corresponding pad; the positioning of the quasi-distance is determined by the servo motor driving the die frame through the ball screw drive to move up and down to the required punching quasi-distance. The punching is completed by the power of the punching cylinder through the hydraulic system.

It is composed of workpiece support roller and turning cylinder. Through the button control on the button station, the processed workpiece is turned out and placed on the left or right side.
