Motor rotor of silicon steel pressure hydraulic press device and Hydraulic system design
Abstract: The design of motor rotor for silicon steel pressure hydraulic press system and hydraulic system mainly to the hydraulic press design and calculate various spare parts and system diagram design analysis . The hydraulic press for three beam four pillars hydraulic press Parts mainly includes hydraulic press main cylinder, the slider, beam, support, filling valve, and tank. Hydraulic press host mainly by the beam, the slider, pole, working platform, guide pin, main cylinder and the top of the cylinder. Through the analysis of hydraulic parameters are calculated, the beams, the slider, table and the guide pin and its main parts design, and can be completed the overall design. The overall design scheme after completing the design of hydraulic cylinder is calculated and checked, motor and pump selection of a series of process. Determine the parameters of hydraulic cylinder after selection of hydraulic components, select the appropriate hydraulic components to ensure the stable operation of the hydraulic system. The last of the hydraulic system performance checking the simple. The design of the hydraulic system main cylinder can realize smoothly fast descending, slow compression, the rolling, discharging, rapid upward. Ejector cylinder can realize on top, ejector bar and steps back.
