Servo press is widely used in machines, automobiles, hardware, coal machinery parts of the forging, used to complete the die forging, precision forging, trimming, calibration and other processes, is a widely used forging and pressing equipment, and its excellent performance of great significance across the ages.
Two, the working principle
Two main motors drive the flywheel, through the main screw to drive the work slide up and down movement, after inputting the start signal, the motor from a standstill state through the pinion gear, large gear drive the work slide to accelerate downward, the motor reaches the pre-set rotational speed of striking the energy requirements, the use of the large gear stored energy to work, so that the forging die workpiece shaping. After the large gear release energy, the work slide in the force rebound at the same time, the motor also started and drive the large gear reversal, so that the work slide quickly back to the pre-set travel position, and then automatically enter the braking state.
Because the slider is affected by the reaction force in the strike during the return trip, the output frequency of the motor only needs about ten percent to make the working slider return to the original position quickly, so the return trip loss is very small. Because the work of the slider back by the motor brake, mechanical brake only in the slider close to the upper stop point only when the work, brake material is not easy to wear, do not need to be replaced often.
