Further, on the output shaft of described reductor, driving gear is installed, two lower rolls are provided with driven gear of the same size on the end of the first bracket side, and driven gear is engaged in driving gear.
The beneficial effects of the utility model are: 1,, by shortening the length of power transmission shaft, reduced the deformation quantity of power transmission shaft when bearing identical moment, thereby reduced the service life that may and extend power transmission shaft that power transmission shaft damages.
2, make the running of lifting motor both sides power transmission shaft and Worm and worm-wheel gearing more synchronous, eliminated the error existing in the adjustable height of top roll two ends.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 to Figure 3, three rolls plate bending machine of the present utility model, comprises base 1, and the first support 2, the second support 3 and drive motors 4 are installed on base 1; Described the first support 2 and the second support 3 are arranged at base 1 both sides, between the first support 2 and the second support 3, have set up two lower rolls 5; The first support 2 and the second support 3 are provided with bearing block 16 moving up and down, the 16 added top rolls 6 that are provided with in bearing block, described drive motors 4 is arranged at the first support 2 outsides, between drive motors 4 and the first support, 2 are provided with reductor 7, reductor 7 is in transmission connection with drive motors 4, and lower roll 5 drives by reductor 7; On base 1 below top roll 6 middle parts, lifting motor 8 is installed, lifting motor 8 both sides are connected with isometric power transmission shaft 9, below the first support 2 and the second support 3 bottom brackets 16, be provided with hoist trunk 17, hoist trunk 17 between two lower rolls 5, the worm gear 11 that the bottom of hoist trunk 17 is provided with worm screw 10 and coordinates with worm screw 10; Worm screw 10 is in transmission connection with power transmission shaft 9, is provided with worm-wheel shaft 12 in worm gear 11, and worm-wheel shaft 12 lower ends are bearing on base 1, and worm-wheel shaft 12 upper ends are provided with screw thread and adaptation is connected with sleeve 13, and sleeve 13 is fixedly connected with bearing block 16 by hoist trunk 17.Wherein, reductor 7 can drive lower roll 5 in several ways, as chain transmission, band transmission and gear drive etc.When top roll 6 is carried out to lifting, by lifting motor 8, drive the power transmission shaft 9 of its both sides rotate and drive worm-and-wheel gear to bring into operation, worm-wheel shaft 12 rises or declines according to the rotation direction different driving sleeve 13 of motor shaft in lifting motor 8 in hoist trunk 17, thereby realizes the control to bearing block 16 and top roll 6 liftings.Because lifting motor 8 is arranged on top roll 6 below an upper sections, so the power transmission shaft 9 of its both sides has shortened half compared with prior art, thereby significantly reduced the deformation quantity of power transmission shaft 9 when bearing same torque, extended the service life of power transmission shaft 9; And because the power transmission shaft 9 of lifting motor 8 both sides is isometric, so it can realize Complete Synchronization when lifting shaft bearing 16 and top roll 6 in the running, thereby has eliminated the error existing between top roll 6 two ends adjustable heights, has improved roll bending precision.
