Example Embodiment

[0014] An automatic liquid filling and draining system for a liquid filling tank: at least including a liquid filling tank 11, an oil supply circuit connected to the liquid filling tank 11, an oil discharge circuit connected to the liquid filling tank 11 and a working mechanism for supplying working oil to the working cylinder 3 The oil circuit, the liquid filling tank 11 is connected with a liquid level sensor and a pressure charging circuit. During operation, the pressure charging circuit fills the liquid filling tank 11 with an air pressure of 0.3-0.5MPa, and the liquid level sensor detects the oil level of the liquid filling tank 11. When When the oil level is lower than the low oil level, the electric control unit 5 controls the oil supply circuit to supply oil to the liquid filling tank 11, so that the oil level of the liquid filling tank 11 handles the working oil level range. When it is higher than the high oil level point of the liquid filling tank 11, The operation of...

Abstract

The invention belongs to a forging oil hydraulic press system, in particular to an automatic liquid supplementing and draining system with a liquid filling tank in a fast forging oil hydraulic press system; the automatic liquid supplementing and draining system with the liquid filling tank is characterized by at least comprising the liquid filling tank, an oil supply loop, an oil discharging loop and a working oil line, wherein the oil supply loop and the oil discharging loop are connected with the liquid filling tank, and the working oil line supplies working oil to a working cylinder; the liquid filling tank is connected with a liquid level sensor and a charging loop; when the automatic liquid supplementing and draining system works, the charging loop charges 0.3-0.5 MPa of air pressure into the liquid filling tank, the liquid level sensor detects the oil level of the liquid filling tank; when the oil level is lower than a low oil level, an electric control unit controls the oil supply loop to supply oil to the liquid filling tank; and when the oil level is high than a high oil level of the liquid filling tank, the oil supply loop stops working, and the electric control unit controls the oil discharging loop to work. The automatic liquid supplementing and draining system has the advantages that the oil absorption condition of a main pump device is improved and the pressure impact and vibration of the system are reduced, thereby the working efficiency of the oil hydraulic press is improved.

Description

technical field [0001] The invention belongs to a hydraulic forging press system, in particular to an automatic fluid replenishment and draining system for a liquid filling tank in a rapid forging hydraulic press system. Background technique [0002] The main pump device of the existing forging hydraulic press generally absorbs oil in the oil tank, and the oil is discharged back to the oil tank through the working cylinder and the unloading valve station. During the whole working process, the main pump device naturally absorbs oil from the oil tank, which is prone to air suction, and the vibration is large during operation, which seriously affects the service life of the oil pump; when the unloading valve releases the pressure, the pressure oil is directly discharged back to the oil tank, causing relatively high pressure in the oil tank and the pipeline. Large shock and vibration affect the working efficiency of the press. Contents of the invention [0003] The purpose of...
