The invention discloses a support device for the driving roller of a plate rolling
machine. The support device comprises a base, a side frame I, a side frame II, driving rollers, a
servo motor, a
leadscrew, and a support device body, wherein a rectangular groove is formed in the base; the lower end of the side frame I is connected to one end of the base through a bolt; the lower end of the side frame II is connected to the other end of the base through a bolt; one ends of the driving rollers are rotatably connected with the side frame I, and the other ends of the driving rollers are rotatablyconnected with the side frame II; the
servo motor is connected with the base through a bolt; one end of the lead screw is rotatably connected with the side frame I, and the other end of the lead screw is rotatably connected with the side frame II; the output shaft of the
servo motor is connected to one end of the lead screw through a
coupling; and the support device body comprises a support seat,a roller stand, a roller, a motor, and a gear II, the bending deformation of the driving rollers during the
barrel roll-forming operation of the plate rolling
machine is effectively avoided, the rollforming operation circular degree of the plate rolling plate is ensured, and the
dynamic balance fluctuation quantity of a circular
barrel after
roll forming is small.
