The design principle of the stamping press is to convert the circular motion into linear motion. The flywheel is driven by the output of the main motor, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to achieve the linear motion of the slider. The motion from the main motor to the connecting rod is circular motion.

(stamping press)The connecting rod and the sliding block need to have the transition point of circular motion and linear motion. In its design, there are roughly two mechanisms, one is ball type and the other is pin type (cylindrical type). Through this mechanism, the circular motion is converted into the linear motion of the sliding block. The stamping press applies pressure to the material to make it plastic deformation, so as to obtain the required shape and accuracy. Therefore, it must cooperate with a group of molds (divided into upper mold and lower mold), place the material between them, and the machine applies pressure to make it deformation. The reaction force caused by the force applied to the material during processing is absorbed by the mechanical body of the punch press.
