The mechanical press machine working design principle of the mechanical power press is to convert the circular motion into a linear motion, and the main motor outputs the force to drive the flywheel. The clutch drives the gear, the crankshaft (or the eccentric gear), the connecting rod, etc. to achieve the linear motion of the slider. The motion of the motor to the connecting rod is a circular motion. There is a need for a circular motion and a linear motion transfer point between the connecting rod and the slider. The design has roughly two mechanisms, one is a spherical type and the other is a pin type (cylindrical type), and the circular motion is performed via this mechanism to a linear motion of the slider. The presses release the force on the material to plastically deform it to obtain the required shape and precision. Therefore, it is necessary to match a set of molds (dividing the upper mold and the lower mold), placing the material between them, and applying pressure by the machine to make it deformed, the reaction force caused by the force applied to the material during processing is absorbed by the mechanical body of the press.
