400 Ton Hydraulic Presses

Description:

400 Ton Hydraulic Press 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 cavity cavity effective 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.

400 Ton Hydraulic Presses

400 Ton Hydraulic Presses


Features:

1. This series of equipment USES liquid as the medium to transfer energy, adopts the advanced hydraulic circuit of sub-mother cylinder, with low oil temperature, air travel speed above 150MM/ s, and working speed below 25mm/s. The oil cylinder adopts inverted installation, greatly reducing the height of the whole machine.

2. When the equipment is in standby, the noise shall not exceed 85 decibels.

3. Adopting four-column and three-plate structure, the vertical accuracy of the movable plate is controlled by four precision guides, and the parallel precision of the lower working face and any point of the upper working face is below 0.1mm.
