Abstract
The press's press mechanism is an important part of the press. And also is the hard core. High-speed precision press in the press process needs to bear their own eccentric crank inertial force, inertial force and the slider up and down the main drive components such as thermal expansion caused by a series problems with high speed. According to the current design of the structure in the country can not effectively solve the core issue of these technologies. Thus it limits the development of the domestic high-speed punching and stamping technology. this project is design to get over the core technology. And to simplify the traditional press's press mechanism. By using Pro ENGINEER,based on the crank-connecting rod mechanism, static conditions by the equivalent substitution method with two quality equivalent to transforming the quality of the connecting rod to the connecting rod and crank pin of the hinge point and install the balance device both under the slide and the both ends of the crank, and using the connecting rod bearing lubrication duct forced circulation cooling system, to ensure to counteract the inertia force and clean up the thermal expansion. than optimize designing the press agencies' every transmission parts. The body use gary cast iron which is good at absorbing the quake and optimize designing the structure, in order to advance the bending rigidity. And by using prestressed rolling guide so that the slider has a sufficiently high guiding precision. The results show that the project design to meet the high-speed precision press's special machine requirements, completely overcome the inertia and thermal expansion. And also further improve the efficiency of stamping. And it will be a solid foundation for the development of high-speed precision press.
