Problems solved by technology

Due to the different pressure values ​​to be achieved in the process of pressing different workpieces, when the pressure is released, the quick forging valve opens the same range regardless of the oil pressure of the main oil pipe, and the quick forging valve The valve cannot adjust the opening degree according to the oil pressure of the main oil pipe, and the hydraulic system cannot adapt to the pressure relief speed of the hydraulic system according to the oil pressure value of the main oil pipe; when the oil pressure of the main oil pipe is very high, if the quick forging valve is fully opened , the pressure relief speed of the hydraulic oil is very fast, which is easy to cause the impact of the hydraulic oil and the vibration of the hydraulic system, which seriously affects the life of the hydraulic control system of the forging hydraulic press, brings danger to the hydraulic press, the workpiece and the operator, and increases the pressure of the hydraulic control system. Future maintenance costs of the system

Abstract

The invention relates to the technical field of C-frame forging hydraulic presses, in particular to a C-frame hydraulic press servo system applicable to forging. The system comprises a servo device, a servo system and a pressure sensor, wherein the servo device is electrically connected with the servo system and the pressure sensor, and the servo system is electrically connected with the pressure sensor. With the C-frame hydraulic press servo system applicable to forging, the servo device and the servo system are arranged, the rapid forging technology of forged pieces is realized, and the forging production efficiency is improved; and the pressure sensor is arranged, pressure compensation in the forging process is realized, and the forging precision is improved.

Description

technical field [0001] The invention relates to the technical field of single-arm forging hydraulic presses, in particular to a single-arm hydraulic press servo system suitable for forging. Background technique [0002] Single-arm hydraulic forging presses are common equipment for small and medium tonnage forging. With the rapid development of the metal rolling industry, the requirements for its working speed and forging precision are getting higher and higher. Due to the different pressure values ​​to be achieved in the process of pressing different workpieces, when the pressure is released, the quick forging valve opens the same range regardless of the oil pressure of the main oil pipe, and the quick forging valve The valve cannot adjust the opening degree according to the oil pressure of the main oil pipe, and the hydraulic system cannot adapt to the pressure relief speed of the hydraulic system according to the oil pressure value of the main oil pipe; when the oil pressu...
