A punch is a punching press. In national production, the stamping process saves materials and energy compared with traditional machining, has high efficiency, does not require high technical requirements for operators, and can make products that cannot be achieved by machining through various mold applications. Its uses are getting wider and wider.

Stamping production is mainly for sheets. Through the die, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts can be made, which are widely used in various fields. Such as the switches and sockets we use, cups, cupboards, dishes, computer cases, and even missile aircraft... There are many accessories that can be produced by punching through molds.

The design principle of the punch press is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to operate to achieve the linear motion of the slider, from the main motor to the The movement of the connecting rod is a circular motion.

Between the connecting rod and the slider, there needs to be a transition point for circular motion and linear motion. There are roughly two types of mechanisms in its design, one is a ball type and the other is a pin type (cylindrical type), through which the circular motion is moved. Converted to linear motion of the slider. The punch presses the material to plastically deform it to obtain the required shape and precision. Therefore, a set of molds (upper mold and lower mold) must be matched to place the material in between, and pressure is applied by the machine to deform it. , The reaction force caused by the force applied to the material during processing is absorbed by the punching machine body.

Punch presses are widely used in stamping and forming of electronics, communications, computers, household appliances, furniture, transportation, (automobiles, motorcycles, bicycles) hardware components.
