The invention discloses a ten-thousand-ton free forging press main pump buffer unloading control cover plate. The ten-thousand-ton free forging press main pump buffer unloading control cover plate comprises a two-position four-way solenoid valve, a cover plate body, a cartridge valve, a first damping screw and a second damping screw; the cover plate body is provided with three oil ports corresponding to an oil port P, an oil port B and an oil port T of the two-position four-way solenoid valve in a one-to-one manner; during forging pressing, the two-position four-way solenoid valve is powered on to achieve reversing, the P-B oil ports of the two-position four-way solenoid valve are communicated, pilot control oil of the cartridge valve flows through a P-B cavity of the two-position four-waysolenoid valve from X-P channels of the cover plate body to enter a middle cavity of the cover plate body finally, a valve element is pressed and locked through the second damping screw, the cartridge valve is closed, and oil coming from a main pump enters the system to achieve pressing; and after pressing is completed, the two-position four-way solenoid valve is powered off, B-T oil ports of thetwo-position four-way solenoid valve are communicated, guide oil of the valve element of the cartridge valve passes through the B-T oil ports of the two-position four-way solenoid valve and the firstdamping screw to flow back into an oil return box, and the orifice diameter of the first damping screw is smaller than the orifice diameter of the second damping screw.
Description
technical field [0001] The invention is applied to the technical field of the unloading control block of the main pump outlet of the free forging press, and particularly relates to a control cover plate for buffering and unloading of the main pump of the 10,000-ton free forging press. Background technique [0002] With the continuous development of my country's equipment manufacturing capacity, the number of 10,000-ton free forging presses in my country is also increasing. The 10,000-ton open die forging press is fast, and the flow rate of the main pump is large. At the end of forging, especially at the end of the pier roughing process, the main pump is unloaded at high pressure and large flow, and the impact of the pipeline is severe, with loud noises and vibrations, and the welding joints of the pipeline are often cracking, the stability of the equipment is seriously affected. Contents of the invention [0003] The technical problem to be solved by the present invention...
