Embodiment Construction

[0050] figure 1 It is a schematic structural diagram of a hydraulic accumulator press according to an embodiment of the present invention. The present invention provides a hydraulic accumulator press, which generally includes: an air storage tank 12, an oil tank 13, a hydraulic oil pump 14, an accumulator 1, a press body I and a hydraulic valve assembly II. Among them, the oil tank 13 is used to provide hydraulic oil. The hydraulic oil pump 14 has an oil inlet and an oil outlet, and the oil inlet of the hydraulic oil pump 14 is connected to the oil tank 13 for pumping hydraulic oil. The accumulator 1 is used to store and release energy. The press body 1 is used to provide a pressing place for the workpiece and to press the workpiece. The hydraulic valve assembly II is connected with the air storage tank 12, the press main body I, the hydraulic oil pump 14, the oil tank 13 and the accumulator 1, so as to realize the supply of the hydraulic oil pump 14 to the accumulator 1. ...

Abstract

The invention discloses a hydraulic energy-storing press machine, and relates to the technical field of press machines. The hydraulic energy-storing press machine comprises a gas-storing tank, an oil box, a hydraulic oil pump, an energy-storing device, a press machine main body and a hydraulic valve assembly. Through different combination of the hydraulic valve assembly, the hydraulic oil pump and the energy-storing device, different working modes of the hydraulic energy-storing press machine are achieved, the different working modes comprises a pressing mode, a constant energy forging mode or a limiting forging mode. According to the hydraulic energy-storing press machine, energy is released by using the energy-storing device, pressure releasing speed is fast, according to the test, the speed of forging of the energy-storing device is several tens of times of the pressing speed of the original hydraulic pump, therefore, under the same pressure condition, energy consumption can be remarkably reduced, and pressing speed can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a hydraulic accumulator press. Background technique [0002] Presses are indispensable processing equipment in industrial production. It is a machine that uses liquid as the working medium to transfer energy to realize various processes. [0003] Existing presses include a body, hydraulic pumps and hydraulic valves. The press is pressed by the hydraulic pump to complete the ground pressure braking of the press. Due to the slow pressing speed of the hydraulic pump, the pressing speed of the press is slow, which wastes energy and causes high energy consumption. In addition, the pressure of the existing press is relatively low. To increase the pressure value, it is necessary to increase the number of hydraulic pumps or select a hydraulic pump with a larger and higher power, thereby making the energy consumption higher. SUMMARY OF THE INVENTION [0004] One object of the present...
