| Pressure machinery principles | Usually by motor through friction press driven plate and make the flywheel spinning wheel rim, so the press and the friction press, China's largest friction press for 25 trillion cattle. The press with larger specifications hydraulic system, called the flywheel screw press, hydraulic maximum specification is 125 trillion cattle. Then appeared in the electric motor driven directly, it's structure compact machine, transmission links, because less frequent commutation, the demand is higher, to control electrical motor and need special.
Screw press down dead point of without fixed, forged pieces, the bigger, can be repeated blows singles, even can play and inch. Strike force and deformation of the workpiece, large deformation when force is small, deformation (such as cold strike force). In these areas, it is similar with the hammer. But it's slider speed is low (about 0.5 meters per second, which is only 1/10), force through, so smooth closed frame, the vibration is much smaller than the hammer, don't need a large base. Press with sliding insurance institutions, the maximum force in the nominal pressure within 2 times, in order to protect the equipment safety.
The machine is equipped with a lower top forgings. The screw press both forging hammer, mechanical press of metalforming machinery, universal, can be used for forging, cutting, etc. In addition, the screw press, especially the friction press manufacture simple structure, easy, so widely used. The screw press is productivity and low efficiency.
