Forging hydraulic press pump accumulator transmission system and pressure transformation method thereof

Abstract

The invention discloses a forging hydraulic press pump accumulator transmission system and a pressure transformation method thereof. The forging hydraulic press pump accumulator transmission system comprises a group of accumulators formed by a plurality of groups of high pressure fluid containers and high pressure gas tanks, the high pressure fluid containers are connected with a high pressure pump, the high pressure gas tanks are connected with an air compressor, the system further comprises high fluid level controllers and low fluid level controllers, the high fluid level controllers and the low fluid level controllers are arranged on the high pressure fluid containers and provided with transmission modules with communication interfaces, the transmission modules are connected with a programmable logic controller (PLC) in a communication mode, and the controlling for the fluid level in the high pressure fluid containers is achieved. According to the forging hydraulic press pump accumulator transmission system and the pressure transformation method thereof, the system can be widely applied to most forging hydraulic presses, and the defects of forging hydraulic press pump accumulator transmission systems in prior art can be overcome.

Description

technical field [0001] The invention belongs to the technical field of forging hydraulic presses, and in particular relates to a pump accumulator transmission system of a forging hydraulic press and a pressure changing method thereof. Background technique [0002] Hydraulic presses are one of the most widely used material forming equipment and are now widely used in various forging processes. With the continuous improvement of forging requirements, the existing large hydraulic presses generally have the function of variable pressure, so that they can use different maximum pressures for different forging materials and processes to meet various forging needs, such as upsetting forgings , need to use greater forging pressure. [0003] Among the existing hydraulic presses, ordinary hydraulic presses using direct transmission systems can generally achieve pressure transformation directly through oil pumps; and hydraulic presses can only use water pump accumulator power transmiss...
