High-speed forging hydraulic, a new type of forging press equipment developed in 1980s, has been commonly acknowledged as one of the main direction for development of free forging equipment. Up to now, the high-speed forging hydraulic presses of medium and light tonnage made by our company are applied in production, with increasingly improved technology to achieve international advanced.In terms of its structural style, the double struts pull-down style dominates present middle and small-sized press(under 20MN),which features low gravity center, good stability short pipeline and little hydrodynamic shock, while large-sized press(above 25MN)adopts push-down style to reduce the inertia of movable parts, which is easy to control and saves energy.Oil pump direct drive is applied in hydraulic transmission. The system's flow capacity and pressure are controlled by switch valves or proportional to maintain good reliability and low cost. LS designed and manufactured high-speed forging hydraulic press of 5MN-125MN, which fully absorb advanced technology from overseas and is designed optimally by experience. These new units containing comparatively high technology can be applied in cogging of steel ingot and press working of free forging, especially suitable for forging materials with high alloying components and hard deformation.Technical Characteristics1. Has the function of fluctuating with press simultaneously and runs steadily in forging process.2. Have the characteristics of strong rigidity, tight structure and convenientmaintenance, which can adapt to bad working environment.3. Proportional relief valves are used in hydraulic circuits of holding and rotating. The holding force and the rotating torque can be selected according to the size of the forgings.4. Chain wheel and pin tooth are in mesh, which insures the stability and accuracy control of the manipulator.5. Infinite speed variation and accuracy control of claw beam rotating and manipulator travelling can be achieved.6. Automatic condition and linkage condition can be achieved under accurate monitoring by computer.
