Design of the Hydraulic System of Lead Plate Coiling Machine

摘要

This paper mainly introduces the process of lead electrolysis, the structure and working principle of lead plate coiling machine and Its' parts, coiling machine components. First of all, rewind section hydraulic system adopts a return to the oil throttle speed control, it is stable and can bear a certain change load, can overcome the stage before the tension fluctuation of the impaction to the rotation speed of hydraulic motor. Secondly, speed and tension control system adopt electro-hydraulic servo valve and proportional relief valve are respectively to the drum speed and output torque control, it has high precision and accurate in speed and tension control. contact coiling section use electro hydraulic servo position control system with close loop control to improve the accuracy of position control. Finally, calculate parameters of each working section of hydraulic control system, verify the hydraulic component model and the rationality of the hydraulic circuit.
