Embodiment Construction

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0063] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0064] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a dual drive toggle rod mechanism for a servo mechanical press and an optimization method. The technical scheme is that an upper toggle rod part comprises a first crank, a first connecting rod, a second toggle rod and a machine body; mechanism optimization is carried out with the stroke adopted as an optimization target; after mechanism parameters of optimization of the upper toggle rod part are acquired, the mechanism parameters are substituted into the entire dual drive toggle rod mechanism; a lower toggle rod part is optimized with the driving torque adopted as an optimization target; and through decoupling iterative optimization of stroke and driving torque of the upper toggle rod part and the lower toggle rod part, the problem that an optimal solution of the dual drive toggle rod mechanism is hard to acquire through adopting a traditional optimization method can be solved, optimization of the dual drive toggle rod mechanism for the servo mechanical press is achieved, the performance and adaptability of the press are improved, the stroke of the machine body structure and a sliding block can be guaranteed to meet the working requirement, the driving torque of the cranks is greatly reduced, and the capacity and cost of a servo motor are reduced. According to the dual drive toggle rod mechanism, the utilization is simple and convenient, the structure is reasonable, and the mechanism is convenient and practical.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a double-drive toggle mechanism and an optimization method for a servo mechanical press. Background technique [0002] The mechanical press is one of the important mechanical equipment, and the mechanical press is mainly the toggle mechanical press. Because the toggle mechanical press has slow working stroke speed, large force ratio, long holding time of the slider at the bottom dead center, and good body rigidity, it is suitable for metal precision pressing or extrusion molding, and is widely used in machinery, Automotive, instrumentation and other industries. [0003] Due to the relatively fixed movement mode of the slider of the traditional toggle mechanical press, single function of the press, poor process adaptability, and high total energy consumption due to the continuous rotation of the flywheel driven by the motor, it is not suitable for the development of modern ...
