Title:
HIGH-EFFICIENCY TRANSMISSION FREE FORGING HYDRAULIC MACHINE AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/184098
Kind Code:
A1
Abstract:
The present disclosure relates to a high-efficiency transmission free forging hydraulic machine and an operation method therefor, the machine comprising: a hydraulic cylinder, a hydraulic pump and pressurized energy storage devices. The high-efficiency transmission free forging hydraulic machine is provided with two sets of pressurized energy storage devices between the hydraulic pump and hydraulic cylinder thereof, such that under the action of a control system, the two sets of pressurized energy storage devices may alternately supply isobaric pressure oil or pressurized pressure oil to the hydraulic cylinder of the free forging hydraulic machine. Therefore, when the hydraulic pump is operated at a lower pressure state, the hydraulic cylinder in the free forging hydraulic machine may continuously obtain the isobaric pressure oil or the pressurized pressure oil, thus achieving the objective of residual energy storage and high-efficiency transmission of the hydraulic machine. The high-efficiency transmission free forging hydraulic machine has reasonable resource allocations, a simple setting structure, a good pressurization effect, saves energy and reduces consumption.
