Pressure oil tank liquid and oil supplementing system and method

Abstract

The invention relates to a pressure oil tank liquid and oil supplementing system and method. An inflation device is connected with a pressure oil tank, the pressure oil tank is provided with an air pressure safety valve and an air pressure measuring deflation device, the pressure oil tank is connected with a die assembly cylinder through a liquid supplementing pipeline switch valve and a liquid supplementing switch valve, the upper portion of a press moving beam is connected with the die assembly cylinder, and the lower portion of the press moving beam is connected with a press return cylinder. According to the pressure oil tank liquid and oil supplementing method, in the rapid descending process of the forging press moving beam, the pressure oil tank is adopted for rapidly supplementing liquid and oil to the die assembly hydraulic cylinder. The pressure oil tank does not need to be placed on the top of a press frame, the height of the press is effectively reduced, the requirements forthe height of production plants are also reduced, meanwhile, a dangerous source that a plant crown block is likely to collide with an oil containing tank on the pressing machine to cause accidents isreduced, the method is adopted for replacing large-flow low-pressure oil pump liquid and oil supplementing, and the equipment energy consumption and the equipment operation cost are reduced.

Description

technical field [0001] The invention relates to a liquid filling and replenishing system for a pressure oil tank, in particular to a method for filling and replenishing a pressure oil tank. Background technique [0002] With the rapid development of my country's industrial level, forging technology, especially die forging and multi-directional die forging technology, has been valued and favored in aviation, aerospace, nuclear power, automobile and other fields due to its high quality, precision, high efficiency, material saving, energy saving and other advantages. As the core equipment of forging technology, the forging press is an important technological action in the working process of the forging press. The quick lowering of the moving beam is a necessary measure to realize the energy saving and high efficiency of the forging press, so that the working process of the forging press saves time. And reduce energy consumption. During the rapid lowering process of the moving be...

Problems solved by technology

For large-scale forging presses, the frame is high, and limited by the height of the factory building, it is impossible to use the upper oil tank filling and oil replenishment scheme, and the high-flow low-pressure oil pump will cause increased energy consumption, equipment costs and operating costs. additional questions
