Abstract：

A kind of mechanism structure of servo CNC punching press was designed to realize the precise high-speed stamping of the air conditioner fin. The design of the overall structure of main machine, the bed structure, the transmission system, the closed height adjusting system and the hydraulic system were mainly introduced. The closed nodular cast iron cast structure of overall framework bed was designed based on the analysis of advantages and disadvantages of welding, the features of cast structure and nodular cast iron, and the loading features of framework structure; the transmission system based on servo motor together with gear reinforcement mechanism was designed to meet the requirements of high speed and large force stamping of fin; the height adjusting mechanism combined with servo motor and adjusting screw was designed according to the characteristics of helical transmission; and the hydraulic overload protection system was designed to realize the pressure balance of slider, the buffer and protection of bed, and the lift and change of die. The calculated results show that the bed structure of main machine has high strength and stiffness, and the transmission system, the closed height adjusting system and the hydraulic system are suitable for the press movement in the production of fins.
