摘要：
Taking a new type of full-fiber crankshaft forging hydraulic press as the research object, an upsetting-bending stroke coordination control is studied to improve crankshaft forming accuracy. A master-slave proportion integration differentiation (PID) coordination control strategy based on velocity feed-forward is proposed to improve the coordination control accuracy. The structure and working process of the full-fiber crankshaft forging hydraulic press are introduced, and a mathematical model of the upsetting and bending control system are established. The coordination control strategy is verified experimentally. The experimental results show that the maximum tracking error of the coordination control strategy is reduced by 66% compared with the traditional PID controller, and the coordination motion accuracy is improved effectively.
