With a wide range of USES, production efficiency higher characteristic, pressing machine can be widely used in cut off, punch, dropping material, bending, riveting and forming, etc. Craft. Through to the metal die-casting strong pressure on the metal plastic deformation and fracture occurred to processed into parts. Mechanical press work by motor through the triangle driving belt pulleys big (usually concurrently flywheel), after gear pair and clutch drive slider-crank mechanism, make the slider and the punch line to the downside. Mechanical press in forging press after completion of work to the slider uplink, automatic clutch withdraws, and crank shaft automatic device connected, make the slider to stop in up stoper nearby. Crank press machine belongs to the mechanical transmission kind of press, is an important pressure processing equipment, it can carry out all the stamping, die forging process, directly produced semi-finished products or product. Therefore, crank press in car, agricultural machinery, electronics, medical machine, national defense, aerospace and daily necessities, etc. industrial departments to a wide range of applications. With the development of industry, crank press the number and the variety of more and more, more and more high quality requirements, stressful, machinery manufacturing industry in his and other industrial production of the role of the press is getting more and more significant, improve mechanical automati
