Abstract 

Slider-crank Mechanism is the main functional element of the precision press for Al-alloy investment casting with thin walled section. Through the transmission mode like gear, belt and chain, the precision press can transfer power to the functional element and press the thin-walled aluminum sheet into barrel-shaped ones. The mainly researching contents were showed as below: Introduced the classification of press, especially introduced the current situation of research and production for it at home and abroad. Analyzed and introduced general structure of the precision press for Al-alloy investment casting with thin walled section, mainly including the mechanical structure and the design parameters. The reducer in precision press is designed and calculated by using the optimization toolbox in MATLAB, and optimization calculation is done with the volume of gearbox being the objective function. Designed, calculated and checked the other transmission sections(including the open-typed spur gears, bevel gears, belt transmission and chain transmission), connectors(including bonds and bolts) and axle system. Completed the 3-d modeling and assembling of different parts based on ProE Software. Introduced the 3-d modeling into SolidWorks software and made kinematics simulation.

Keywords: precision press, matlab, optimization, modeling based on ProE, kinematics simulati
