The principle of the punching machine is to drive the flywheel through the motor, and through the clutch, the transmission gear drives the crank connecting rod organization to move the slider up and down, and drives the drawing die to form the steel plate. The so-called double action means that the press has two sliders, which are divided into an inner slider and an outer slider. The inner slider drives the punch or die of the mold, and the outer slider drives the blank holder ring on the mold. The main action of the blank holder is to press the edge of the steel plate, and then the inner slide block moves to stretch.

The planning principle is to convert circular motion into linear motion. The main motor generates power to drive the flywheel. The clutch drives the gear, crankshaft (or misaligned gear), connecting rod, etc., to achieve the linear motion of the slider, from the main motor to the connecting rod. The movement of the rod is a circular movement.

Between the connecting rod and the sliding block, there needs to be a transition point for circular motion and linear motion. There are roughly two types of organization in the planning, one is a ball type, and the other is a pin type (cylindrical type). The circular motion is moved through this organization. Converted into linear motion of the slider. The stamping machine applies pressure to the data to deform it plastically to obtain the required shape and accuracy. Therefore, it is necessary to cooperate with a set of molds (upper and lower molds), place the data in between, and apply pressure by the machine to make Its deformation, the reaction force formed by the force applied to the material during processing, is absorbed by the mechanical body of the punching machine.
