Patent ID: 10850468

Abstract:
A high-speed hydraulic forging press is disclosed. The high-speed hydraulic forging press includes a forging hammer, a movable beam, a main hydraulic cylinder, a single-rod elevation hydraulic cylinder, a plurality of main hydraulic pumps, a high-pressure energy accumulator, an intermediate-pressure energy accumulator, an oil tank, a programmable logic controller and a valve-regulation system. During a rolling process, when a rolling resistance applied to the forging hammer increases to cause pressure in the main hydraulic cylinder to reach a predetermined value, the programmable logic controller controls the valve-regulation system so that the high-pressure energy accumulator stops supplying the hydraulic oil to the main hydraulic cylinder, and that the hydraulic oil in the main hydraulic cylinder is supplied by at least one of the plurality of main hydraulic pumps. The high-speed hydraulic forging press exhibits remarkable advantages including a reasonable resource allocation, a simple structure, low equipment investment, and high energy utilization.
