[CN 202210307125.3] A Quantitative Control Method for Rotation Cooperation of Manipulator Chuck of Precision Forging Machine
[CN 202210307125.3] A rotary cooperative quantitative control method for a precision forging machine manipulator chuck Title: A rotary cooperative quantitative control method for a precision forging machine manipulator chuck Application Number: CN 202210307125.3 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 rotary cooperative quantitative control method for a precision forging machine manipulator chuck. For each forging pass, the method includes: inputting the forging process parameters of the precision forging machine for each forging pass; Establishing a two-dimensional rectangular coordinate system, calculating the intermittent time of hammer forging, the requirements of the chuck rotation speed, and selecting the chuck rotation speed; Calculating the expected position function of the sliding sleeve of the worm moving along the axial direction through the hammer position change curve; The electro-hydraulic position servo working system is controlled by the expected position function of the sliding sleeve, the chuck drives the forging to rotate at a set constant speed to match the forging; the operating machines on both sides are matched to feed on the guide rail until the diameter of the forging meets the requirements after forging, and the current forging pass is ended. The invention avoids the rotation and distortion of the forging when it is pressed down by the hammer head, coordinates the completion of the forging process, and makes up for the blank of the quantitative control of the chuck.
