毕业设计任务书1000KN. Conditions on the hydraulic cylinder hydraulic cylinder load analysis to determine changes in the hydraulic system developed action plans and the electromagnet order. And the main hydraulic cylinder design to calculate the size of the main cylinder and the flow rate of master cylinder for access and security, travel limit switches to control through the stroke. Calculated according to the technical requirements and design options hydraulic pump, GE series of solenoid valves and other hydraulic components. The hydraulic system pressure loss and temperature rise of checking, hydraulic system design to meet the hydraulic requirements of the order cycle of action, designed to achieve four-column hydraulic press plastic material, forging, stamping, cold extrusion, straightening, bending and other forming processes. The PLC control system, hydraulic system used by a variety of hydraulic pumps and cylinders and valves to achieve energy conversion, regulation and distribution, complete a variety of process action cycle. Hydraulic press using a centralized arrangement, the hydraulic system and control of oil sources outside the regulating device in the host.
The hydraulic machine structure is compact, reliable sensitive action, speed, energy consumption, low noise, stress and travel can be adjusted within the limits prescribed, simple operation.
Keywords: Four-column hydraulic press; hydraulic system; PLC
