Mainframe mainly by the beam、guided、worktable、mobile beams、master cylinder、cylinder head out of components etc. This paper focuses on the hydraulic system design. Through specific parameters and hydraulic mechanic situation analyzes, formulation of a master control program. By contrast, developed hydraulic control system diagram.Hydraulic systems use cartridge valve integrated control system, integrated cartridge valve control system has good sealing, flow capacity, small pressure loss characteristics etc. To solve the master cylinder express entered the shortage of oil supply in the top of the mainframe installed oil tank. Master cylinder for the speed of access restrictions and security through the trip exchanging to control switches.To ensure the quality of the work-piece molding, in the hydraulic system installed packing loop through packing work-piece stability molding; To prevent hydraulic shocks, pressure relief system with a loop to ensure that this equipment can be a safe and stable work. In addition, the paper hydraulic station on the overall layout of the key components of the hydraulic structure、shape、technique for a specific design.By the loss of hydraulic system pressure and temperature checked. Hydraulic system is designed to meet the hydraulic action sequence and cycle requirements can be achieved by forging plastic materials, stamping, cold extrusion, straightening, bending, and other molding processes.
