Kinematics Analysis of Main Transmission Mechanism of Double Servo Drive Press Based on Rigid-Flexible Coupling

In this paper, the main transmission mechanism of the double servo drive symmetrical toggle press was taken as the object of study. The theoretical derivation of its motion characteristics was carried out. A parametric model was established to analyze its rigid body kinematics. The kinematic performance was improved by rigid-flexible coupling. The research results could provide an important reference for the development of large-tonnage wide-table double servo drive press.
