The principle of the punching machine is to convert the circular motion into linear motion. The main motor drives the flywheel and then drives the gear, crankshaft, connecting rod by clutch. The motion from the main motor to the connecting rod is circular motion.
The transition point for the circular motion and linear motion between the connecting rod and ram is very necessary. There are two main structures, ball type and pin type. This structure will convert the circular motion into linear motion. The punching machine will put the pressure on the material and deform it plastically to obtain the required shape and precision. Therefore, it must work with one set of mold(upper punch and bottom die) to deform the material which is put between the punch and die by exerting force.
Punching machine is widely used in stamping and forming of electronics, communications, computers, household appliances, furniture, vehicles, (automobiles, motorcycles, bicycles) hardware parts.
