Title The test for a key dynamic performance of high speed press,repeat accuracy of bottom dead center
Abstract
With the development of high speed press and the development of high speed
Press，the dynamic performance of high speed press has been paid more and more attention．The important evaluation standard of dynamic performance is the bottom dead center repeat ability positioning accuracy．Improving the bottom center precision is the problems of all the press industry.In this work, we built a testing system with software and hardware test platform, for bottom dead center repeat accuracy ,a key performance parameters of high speed press. Then this work introduced the function of each part in hardware platform , and document collection and test procedure in LabVIEW for repeat accuracy of bottom dead center. Through the research analysis give high-speed press analysis and experiment about bottom dead center repeat ability positioning accuracy using modern technology．Find out the influence factor of bottom center precision according．And put forward some improvement scheme and measures．For the improvement of
dynamic performance of high-speed press，it has important practical value and significance to accelerate the development to high precision and high speed．
Keywords: High-speed press Repeat accuracy of bottom dead center
