The four-column hydraulic press belongs to the braking device of the control system, which is generally used to control the punching, forging and forming of metal objects, air hammer, lifting, digging and so on. A hydraulic device in a machine works with high pressure liquid. Hydraulic devices are used in machines that need to produce a lot of force over a short distance. Like hydraulic jacks that lift heavy objects off the ground. The hydraulic system has two pistons that move up and down in a circle. A fluid such as oil is filled to the bottom of each piston's circular pad, and the two loops are connected by a pipe. When the piston depresses, the liquid pressure in the whole hydraulic system increases.
Four-column hydraulic press stroke control lift when processing von berg systeme reversing main lines are not as long as through the main directional control valve, the oil return also the first to the valve control, reversing the objects in the block iron and leverage effect, the first to braking valve core on the cone can be gradually turn down hydraulic cylinder oil return channel, to complete a job unit prefabrication, when work platform velocity is very small, only start reversing main lines. When the saving opening is set, no matter how fast the original speed of the working table, the advance braking stroke of the working table remains the same. The pressure offset variable pump has the characteristic that the flow rate decreases with the increase of the working pressure actively. The output flow rate of the hydraulic pump actively compensates the flow required by the leakage when the pressure is maintained, and can adjust the characteristics and use the pressure of the hydraulic cylinder actively with the change of the leakage amount. The pressure is stable and the efficiency is high. It is suitable for the induction of pressure retaining circuit in the oil circuit of clamping equipment or four-column hydraulic press.
