【Abstract】 In order to solve these problems of traditional steel rod shearing technology like continuous shearing,greasy dirt of ends and low sizing precision,the design scheme of oscillating sizing shear cam mechanism for PC steel rod based on mechanical-electro hydraulic technology was presented. Technical composition of oscillating cam shearing system was explained. By using mechanism theory,the conjugated cam shearing mechanism was presented. The working principle of hydraulic system based on PLC control was researched,and cycle process of shearing mechanism was analyzed. The results show that the designed oscillating sizing shear cam mechanism for PC steel rod has the characteristics of simple structure and high shearing precision,and it can fulfill the requirements of engineering.更多还原
