[CN201610949971.X] Dual-drive toggle mechanism for mechanical press and optimization method thereof
[CN201610949971.X] a dual-drive toggle mechanism and optimization method for mechanical press title: a dual-drive toggle mechanism and optimization method for mechanical press application number: CN201610949971.X applicant: Guangdong university of technology application date: 2016-10-26 patent type: invention application the present invention discloses a dual-drive toggle mechanism and optimization method for mechanical press, the invention divides the dual-drive toggle mechanism into an upper toggle part and a lower toggle part. The upper toggle part is composed of a first crank, a first connecting rod, a second toggle and a body, and the lower toggle part is composed of a second crank, The second connecting rod, the first toggle rod, the third toggle rod, and the slider. The upper toggle rod part takes the stroke as the optimization target for the mechanism optimization, through the decoupling iterative optimization of the upper and lower toggle part stroke and driving torque, the optimization of the dual-drive toggle mechanism is realized to improve the performance and adaptability of the press, which can greatly reduce the driving torque of the crank and reduce the capacity and cost of the servo motor under the premise of ensuring the body structure and the slider stroke to meet the working requirements. The invention is simple and convenient to use, and the designed dual-drive toggle mechanism has a reasonable structure, is convenient and practical.
