Abstract

The invention discloses a super dead slow speed closed loop control mechanism for a forging hydrodynamic press, which comprises an industrial computer, a principal controller PLC that controls the forging hydrodynamic press and is connected with the industrial computer through an industrial Ethernet. The principal controller PLC is connected with one end of the proportional servovalve unit and one end of the proportional pump unit that is controlled by the principal controller PLC; another end of the proportional servovalve unit and the proportional pump unit is connected with a hydraulic cylinder of the forging hydrodynamic press which is driven by the proportional sevovalve unit and the proportional pump unit. A position sensor which is connected with the principla controller PLC and feeds signals of the position of the hydraulic cylinder back to the principal controller PLC is arranged on the hydraulic cylinder. The position sensor is connected with a position input module inside the principal controller PLC. The proportional servovalve is connected with an anolog variable output module inside the principal controller PLC. The invention comes in simple control structure, stable control effect, high automation, high accuracy, high real time and high reliability, with a control effect of a super dead slow speed and constant strain, realizing freewill adjustment when the speed is between 0.002 to 12mm/s in the isothermal forging art work, and has constant strain control capability when the speed is between 0.002mm/s to 0.03mm/s, and 0.04 to 0.06mm/s.

Description

technical field [0001] The invention belongs to a forging hydraulic machine, in particular to an ultra-micro-speed closed-loop control structure of a forging hydraulic machine with a simple control structure and ultra-low speed and constant strain. Background technique [0002] With the rapid development of the aerospace industry, the demand and processing requirements for aerospace materials such as titanium alloys have been increasing recently, so the demand for hydraulic machines with high control requirements such as ultra-low speed and constant strain for the characteristics of aerospace materials such as titanium alloys is increasing. . However, the hydraulic press with high control requirements such as ultra-low speed and constant strain has become a problem that is difficult to solve at present due to its extremely high control requirements. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention p...
