The press is a stamping press, and is often used for forming product parts by performing various stamping processes on plates by matching with a group of dies placed on the press, and is widely applied to stamping and forming of electronics, communication, electrical appliances, furniture, vehicles, hardware parts and the like. When the press machine works, the lower pressing block drives the upper die to move relative to the lower die, the rotary motion of the crank is converted into linear motion, and the motor drives the gears, the crank (or the eccentric gear), the connecting rod and the like to operate to convert the rotary motion into the up-and-down reciprocating motion of the sliding block, so that the stamping is realized.
The crank type press is most applied in actual production operation, has long stroke, uniform load borne by a punch press and easy manufacture of a crank mechanism, and is applied to punching, bending, stretching, forging and other almost all press processing. However, most of the existing double-crank type presses are directly connected by a motor, a belt wheel, a driving shaft and a gear, and when the press works, the transmission mechanism and the pressing mechanism are damaged due to overlarge torque on the transmission shaft.
