Problems solved by technology
The second-generation mechanical press uses clutches, etc., which consume energy when the flywheel is idling, resulting in serious energy loss
On the one hand, this increases the consumption of friction materials, and at the same time, this part of energy has not been recovered and utilized

The invention discloses a drive and transmission system of a braking energy-saving assistant type closed type multi-point servo press. A double-edge layout is adopted for the drive and transmission system. The drive and transmission system comprises two main servo motors. The main servo motors are connected through a small belt wheel, a belt and a large belt wheel. The large belt wheel is connected with a small gear through a transmission shaft. The small gear is meshed with a large gear. The large gear is connected with a crank shaft. The crank shaft is connected with a sliding block through a connecting rod. The other end of the crank shaft is connected with an inner gear ring of a planet gear. The inner gear ring, the planet wheel and a central wheel form a planet gear transmission mechanism. A braking energy-saving assistant servo motor is connected outside the central wheel. The braking energy-saving assistant servo motor can help to output torque and can also be used as a generator to recover energy. The drive and transmission system can remarkably improve the performance, of energy conservation, servo and precision, of the closed-type multi-point press so as to further improve the bearing capacity and the working efficiency of the closed-type multi-point press.
Description
technical field [0001] The invention belongs to the technical field of forging equipment, and in particular relates to a drive and transmission system of a brake energy-saving and power-assisted closed multi-point servo press. Background technique [0002] Forging equipment is divided into three generations: steam hammer (steam as power), mechanical press (AC asynchronous motor as power), servo press (AC permanent magnet synchronous servo motor as power). [0003] The second-generation mechanical press is the modern mainstream forging equipment, accounting for about 80% of the entire forging equipment. It adopts the mechanical transmission mode of AC asynchronous motor, clutch, brake, gear reduction system and crank slider mechanism. Because the starting current of the AC asynchronous motor is 5 to 7 times the rated current, and the AC asynchronous motor cannot be started and stopped frequently (a dozen or dozens of times per minute), to meet the requirements of starting and...
