Embodiment Construction

[0050] figure 1 It is a structural schematic 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 main body I and a hydraulic valve assembly II. Wherein, 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 with the oil tank 13 for pumping hydraulic oil. The accumulator 1 is used to store and release energy. The press main 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 main body of the press machine I, the hydraulic oil pump 14, the oil tank 13 and the accumulator 1, and is used to realize the transfer of the hydraulic oil...

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 energy storage 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 body, hydraulic pump and hydraulic valve. The press is pressed by the hydraulic pump to complete the pressing action of the press. Due to the slow pressing speed of the hydraulic pump, the pressing speed of the press is relatively slow, thereby wasting energy and causing high energy consumption. In addition, the pressure of the existing press is relatively low. If the pressure value is to be increased, it is necessary to increase the number of hydraulic pumps or select a hydraulic pump with a larger power, which leads to higher energy consumption. Contents of the invention [0004] An object of the presen...
