Punch is a punch press. In the national production of stamping process than traditional machining materials and energy saving, high efficiency, operator technical requirements are not high and through a variety of machining tooling can make products that cannot be reached by these advantages, thus it is used more widely.

Production is mainly aimed at the plate. Through a die, blanking, piercing, forming, drawing, shaping, fine blanking, plastic, riveting and extrusion and so on, are widely used in various fields. As we switched socket, Cup, cupboards, plates, computer chassis and even missile aircraft ... ... There are so many accessories can punch through the mold production.

Punch the design principle is converting circular motion into linear motion, by the main motor output drive flywheel, clutch gears, crankshaft (or eccentric gear), connecting rods and other works, to reach the linear movement of the slider, the main motor connecting rod motion for circular motion.

Connecting rod and slide between the circle and linear transfer contact, generally, there are two kinds of bodies on its design, a ball, a pin-type (cylinder type), through this body converting circular motion into linear movement of the slider. Punching pressure against material, plastic deformation, and get the desired shape and precision, so you must meet a set of molds (upper and lower), material, machine put pressure on its deformation, machining applied strength of materials as a result of the reaction, and absorbed by the mechanical body punch.
