Bending correction of main shaft of shredder

The main shaft of the waste shredder machine is one of its important structures. The influence of the main shaft bending:   1. Affect the service life of the spindle;   2. The blade produces interference cutting, reducing the service life of the blade;   3. Affect the size of the processed materials;   4. Reduce bearing service life;   5. Not easy to assemble;   6. If the speed reducer is directly connected, the service life of the speed reducer will be reduced; the belt drive is used, and the belt is easy to jump, and the service life of the triangle belt is reduced.   Therefore, it is necessary to strictly require the accuracy of the spindle to ensure the service life of the equipment, increase the yield, and meet customer requirements.  Tear shredder correction steps are as follows:   1. Use a press to correct the fourth stage.  2. Use a four-jaw chuck to clamp the fifth section, use the center frame support structure to support the third section, and align the center of the fourth section. Hit the center eye, then hold it with a thimble, remove the center frame, finish the front and third sections of the fine car, and the vacant part of the rough car.  3. Spindle head change processing. Use a four-jaw chuck to clamp the front section, and use the center frame support structure to support the fifth section, and align the center of the fourth section. Hit the center eye, then hold it with a thimble, remove the center frame, the fifth section of the fine car, and the vacant part of the rough car.
