Problems solved by technology

In this scheme, the power of the servo motor is small, but there are problems that the output power of different types of motors cancel each other out, and the slider can only change speed during the downstroke, and cannot pause or even reverse, so it cannot adapt to some servo stamping processes.

Description

technical field [0001] The invention relates to a device in the technical field of forging machinery, in particular to a six-link servo mechanical press driven in parallel by double servo motors. Background technique [0002] The servo mechanical press is a new type of metal forming equipment using servo drive technology. Due to relying on the controllable drive element—servo motor—to provide power, the servo mechanical press not only has the high motion flexibility of the hydraulic press, but also has the high production efficiency of the mechanical press, and also has the advantages of improving product quality, saving energy consumption and reducing working noise. Advantages are an important development direction of forging equipment in the future. [0003] Most of the ordinary mechanical presses are crank presses driven by asynchronous motors. Generally, a large flywheel that stores and releases energy is designed and installed on the high-speed shaft of its transmissi...
