Abstract

The invention relates to a centering hydraulic system of aluminum ingot tipping equipment, and belongs to the field of hydraulic control equipment. The centering hydraulic system comprises four actuating mechanisms which act synchronously, four oil cylinders which act synchronously and four centering valve groups which act synchronously, wherein each actuating mechanism is driven by one oil cylinder, and each oil cylinder is controlled by one centering valve group. Each centering valve group comprises a proportional reversing valve with a valve element position feedback function, a pressure compensator, a balance valve and a pressure switch. An oil inlet and an oil outlet in one side of each proportional reversing valve with the valve element position feedback function are communicated with an oil tank through pipelines respectively, and two oil outlets in the other side of each proportional reversing valve with the valve element position feedback function are communicated with a rod cavity and a rodless cavity of an oil cylinder through pipelines respectively. The pressure compensators are in series connection with pipelines connected between the oil tank and the proportional reversing valves. The balance valves are in series connection with pipelines connected between the proportional reversing valves and the rod cavity and the rodless cavity of the oil cylinder, and the pressure switches are arranged on pipelines between the balance valves and the rodless cavity of the oil cylinder. The influence of load pressure change is small, the synchronization precision is improved, and the centering effect is ensured.

Description

technical field [0001] The invention belongs to the field of hydraulic control equipment and relates to a centering hydraulic system of aluminum ingot tipping equipment. Background technique [0002] The aluminum ingot tilting equipment is used to turn over the aluminum ingot. In the process of turning over the aluminum ingot, the aluminum ingot needs to be centered. The centering system is used to realize the centering action. The centering system includes four actuators and four oil cylinders, each actuator is driven by an oil cylinder, the piston rods of the four cylinders are extended synchronously, and the corresponding actuators are also extended synchronously, until the four actuators all touch After the aluminum ingot, push the aluminum ingot to the middle position, as the pressure rises and reaches the set value of the pressure switch, it means that the centering action is completed. Traditionally, in order to keep four oil cylinders acting synchronously, synchrono...
