A dual toggle lever drive mechanism for a mechanical press and Optimization Method

The present invention discloses a mechanical toggle press dual drive mechanism and a method for the optimization, the present invention is to divide the double toggle lever drive mechanism for the upper and lower toggle the toggle lever portion, the first portion of the toggle lever crank, first a connecting rod, and a second body composition toggle, the toggle lever portion at a second crank, a second connecting rod, a first toggle lever, the third wrist, the composition of the slider, on the toggle lever portion in a stroke of the optimization target optimization means, to the lower part of the toggle lever drive torque optimization objective, by decoupling the vertical stroke of the toggle lever portion of the driving torque and iterative optimization, optimized double toggle lever drive mechanism to improve the press performance and adaptive, in ensuring the fuselage structure, the slider stroke to meet the requirements of the working premise, significantly reducing the driving torque of the crank, thereby reducing the capacity and cost of a servo motor. The present invention is simple and convenient to use, dual-drive the toggle mechanism designed reasonable structure, convenient and practical.
