Punch press, is a stamping press. In national production, the stamping process, due to the advantages of material and energy savings over conventional machining, high efficiency, low operator skill requirements, and products that can not be machined through various die applications, Its use is more and more widespread.
Stamping production is mainly for the plate. Through the mold, can make blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion, and so on, are widely used in various fields. Such as switch sockets, cups, cupboards, dishes, computer cases, and even missile planes ... we have a lot of accessories that can be made in the form of punches.
Punch design principle is the circular motion is converted to linear motion, the main motor output, driven by the flywheel, driven by the clutch gear, crankshaft (or eccentric gear), connecting rod and other operations, to achieve linear motion of the slider, from the main motor to Connecting rod movement for the circular motion
Connecting rod and slider between the need for circular movement and linear movement of the transfer point, the design of roughly two kinds of institutions, one for the ball, one for the pin (cylindrical), the circular motion through this mechanism Converted into a slider linear motion. Punch to exert pressure on the material, so that its plastic deformation, and get the required shape and accuracy, it is necessary to cooperate with a set of molds (points on the mold and the lower mold), the material placed in between, by the machine to exert pressure to deform , Processing force applied to the material caused by the reaction force, absorbed by the punch machine body.
