[CN 202210307118.3] A quantitative control method of precision forging machine elongation with dynamic cooperation
[CN 202210307118.3] Title of a precision forging machine elongation follow-up cooperative quantitative control method: Application number of a precision forging machine elongation follow-up cooperative quantitative control method: CN 202210307118.3 Applicant: Beijing University of Aeronautics and Astronautics Application Date: 2022-3-25 Patent Type: Application for the Invention The present invention relates to the technical field of precision forging machine control system and provides a precision forging machine elongation follow-up cooperative quantitative control method. The method includes: inputting the forging process parameters of the precision forging machine for each forging pass; Calculating the reverse actual compensation displacement and control period of the chucks of the two side manipulators, and controlling the chucks of the two side manipulators to move relative to the middle forging with the reverse actual compensation displacement with the control period; Starting the precision forging machine system, based on the reverse actual compensation displacement and control period of the chuck, the actual compensation displacement of the chuck of the two side manipulators is converted into electrical signal, and input to the chuck displacement proportional valve to drive the chuck electro-hydraulic position servo system to work; until the forging diameter meets the requirements after forging, the current forging pass is ended. The invention avoids the problem that the forging material will be destroyed, easily bent and deformed, and the processing process will be affected by the energy release inside the forging.
