Abstract

The utility model relates to a rapid pressure-building system for a hydraulic cushion. The rapid pressure-building system for the hydraulic cushion comprises a hydraulic cushion, a displacement sensor, a hydraulic cushion cylinder, a programmable logic controller (PLC), a pressure sensor, a charging valve, a propositional servo valve, an energy accumulator, and a cartridge valve. The hydraulic cushion cylinder is arranged at the bottom of the hydraulic cushion, and the charging valve is connected with a controlled oil pipe of the hydraulic cushion cylinder. The PLC is respectively connected with the displacement sensor, the pressure sensor, the propositional servo valve, the energy accumulator, and the cartridge valve, wherein the displacement sensor is used to detect the position of the hydraulic cushion and the pressure sensor is used to detect the oil pressure in the controlled oil pipe. The cartridge valve, the energy accumulator, and the controlled oil pipe of the hydraulic cushion cylinder are sequentially connected. The rapid pressure-building system for the hydraulic cushion is characterized in that blank holder force is capable of being built for the hydraulic cushion in a short route, and simultaneously the rapid pressure-building system for the hydraulic cushion has the advantages of being highly automated and saving time.

Description

The fast run-up pressing system of a kind of hydraulic die cushion
Technical field
The utility model belongs to the hydraulic press technical field, is specifically related to a kind of fast run-up pressing system of hydraulic die cushion of can be in short stroke setting up the pressure limit for hydraulic die cushion.
Background technology
The pressure stroke of building of hydraulic die cushion is to weigh a good and bad important parameter of hydraulic press performance; At present; Traditional hydraulic die cushion is built pressure and is all had following defective: one, since traditional hydraulic die cushion build the pressure process and all adopt manually-operated workflow; Therefore its automaticity is low, and control accuracy is low, and waste of manpower; Two, build and press stroke big,, therefore build and press stroke ratio bigger because traditional hydraulic die cushion is built the pressure process and adopted manually-operated workflow.
Summary of the invention
The technical problem that the utility model will solve is existing hydraulic die cushion to be built pressing system improve, and proposes the fast run-up pressing system of hydraulic die cushion that a kind of automaticity is high, can be in short stroke set up the pressure limit for hydraulic die cushion.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the fast run-up pressing system of a kind of hydraulic die cushion comprises: hydraulic die cushion, displacement transducer, hydraulic die cushion cylinder, Programmable Logic Controller, pressure sensor, prefill valve, proportional servo valve, accumulator and inserted valve; Said hydraulic die cushion cylinder is installed on the bottom of said hydraulic die cushion; Said prefill valve is connected with the control oil pipe of said hydraulic die cushion cylinder; Said Programmable Logic Controller is connected with pressure sensor, proportional servo valve, accumulator and the inserted valve of oil pressure in the displacement transducer that detects the hydraulic die cushion position, the detection control oil pipe respectively; The control oil pipe of said inserted valve, accumulator and said hydraulic die cushion cylinder is connected successively.
As preferred version, the utility model has also adopted following technical characterictic:
Said inserted valve is a two-way plug-in valve.
Advantage and the good effect that the utlity model has are: one, through adopting Programmable Logic Controller, displacement transducer and pressure sensor, realized hydraulic die cushion is built the intellectuality control of pressing system; Two, through having adopted accumulator, improved the speed that hydraulic die cushion is built pressure, shortened and built the pressure stroke.
