Stamping production is mainly aimed at sheet metal. Blanking, punching, forming, stretching, trimming, fine punching, shaping, riveting and extruding parts can be made through the die, which is widely used in various fields. For example, we use switch sockets, cups, cabinets, plates, computer cases, and even missile planes ... there are many accessories that can be produced by punching machines through molds.

The design principle of punch is to convert circular motion.

Ordinary punching machine

For linear motion, the output of the main motor drives the flywheel, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to realize the linear motion of the slider, and the motion from the main motor to the connecting rod is circular.

For circular motion and linear motion, there must be a connection point between the connecting rod and the slider. There are two kinds of mechanisms in its design, one is ball type, and the other is pin type (cylindrical type). Through these two mechanisms, the circular motion is transformed into the linear motion of the slider. The punch presses the material to plastically deform it, thus obtaining the required shape and accuracy. Therefore, it is necessary to cooperate with a set of molds (divided into an upper mold and a lower mold) to put the material between them, and the machine exerts pressure to deform it. The reaction force caused by the force applied to the material during machining is absorbed by the main body of the punching machine.
