Abstract Forging machinery occupies a very important position in industrial production. It widely used in machinery, electronics, defense and almost all industrial sectors. However, the crank presses are the majority in forging machinery majority, accounting for more than half of the total market share. Crank press is one of the most commonly used cold stamping equipment. It uses a slider-crank mechanism as a movement mechanism, and relies on the drive system to send the movement and energy of the motor to the working bodies. Applying a force to the work piece through the slider so as to achieve the purpose of forging the work piece. The application, classification, domestic situation and development trend of abroad are introduced at the first of this paper. the overall scheme of the transmission system is determined by comparative analysis in the second chapter. According to the overall design scheme, the design calculations and checking of various components of the transmission system are given in the third part. Chapter IV, the three-dimensional maps of the main parts of transmission are draw out. Finally, the design is summarized and the paper presents the improved future prospects.
