A Novel Method for Best Fit Design of Slide Guide Device in Hydraulic Press

Gao Mengdi;Liu Zhifeng;Huang Haihong;Li Xinyu;Hefei University of Technology;  
Based on the energy loss analyses of the sliding pair in slide guide device of hydraulic press,a mathematical model of overall efficiency loss was established.Based on the principles of minimum overall efficiency loss,the numerical calculation method of optimum match clearance in guide device was proposed.And the maximum allowable eccentric load on wedge clearance conditions was proposed based on the calculated optimum clearance.In order to ensure guide device between the pillars and slide wouldn't fail due to the excessive wear,the wear check method under extreme conditions was proposed.According to wear check method,the best guide length was calculated based on the principle of minimum overall efficiency loss.The case analyzed and verified the correctness of the method,which may provide theoretical and methodological references for the design of optimum match in guide device.
