The design of the drive system of the crank underdrive quick presses

Based on production needs, a main transmission mechanism of underdrive speed press was designed in this paper. The design of the main transmission mechanism is the improvements and alternative of sine institutions slider-crank mechanism made. Underdrive and dual slider mechanism were designed, in order to achieve the presses punching process. The nominal pressure angle and the nominal torque were calculated. A preliminary calculation and design of the crankshaft, bearings, slider of the main drive mechanism. Ensure reliable operation and to provide a basis for the optimization design.
