[CN 201710480578.5] Main transmission mechanism and motion planning method of servo mechanical fine blanking press


[CN 201710480578.5] Title of Main Transmission Mechanism and Motion Planning Method of Servo Mechanical Fine Blanking Press: Application Number of Main Transmission Mechanism and Motion Planning Method of Servo Mechanical Fine Blanking Press: CN 201710480578.5 Applicant: Wuhan University of Technology Application Date: 2017-6-22 Patent Type: Application of Invention The present invention proposes a Main Transmission Mechanism and Motion Planning Method of Servo Mechanical Fine Blanking Press, it includes a first crank, a first connecting rod, a second connecting rod, a second crank, a third connecting rod, a slider and a frame. One end of the first crank is hinged with the frame, and the other end is hinged with one end of the first connecting rod. The other end of the first connecting rod is hinged with one end of the second connecting rod and the third connecting rod, and the other end of the second crank is hinged with the frame, the other end of the third connecting rod is hinged with the slider, the slider slides vertically along the guide rail, the first servo motor drives the first crank to rotate around the hinge point, and the second servo motor drives the second crank to rotate around the hinge point. The invention improves the working efficiency of the fine blanking press on the premise of meeting the multiple requirements of the slider stroke, the speed in the nominal stroke and the nominal force in the high-speed fine blanking process.
