Powder molding cold (hot) extrusion metal molding, sheet stretching as well as transverse pressure, bending pressure, penetration and correction plasticity materials such as steel plate, round steel, processing machine simple, stable performance, simple operation.

 

Specification:

250 Ton Hydraulic Presses

250 Ton Hydraulic Presses


Features:

The machine adopts the advanced integrated system of cartridge valve, with compact appearance, light weight, convenient installation and maintenance, high transmission efficiency and good sealing performance. This valve hydraulic cylinder differential connection in the circuit, namely single rod piston cylinder around two cavities are interlinked, so it constitutes the differential connection circuit, hydraulic pump oil directly into the rodless hydraulic cylinder cavity, then two the 3-way magnet valve (solenoid, electricity, hydraulic cylinder to achieve differential connection, the hydraulic pump output pressure oil into the hydraulic cylinder at the same time around the two cavities, but due to the effective area is greater than the rod rodless cavityeffective area, big cavity produce thrust is greater than the small cavity to produce thrust, so the piston downward movement, due to the hydraulic cylinder rod cavity discharge of oil into the hydraulic cylinder of rodless cavity, thus increasing the speed of the piston downward movement,Make the actuator move quickly, the valve leak less, the flow resistance is small, change quickly, the impact is very small and so on.
