Description

Technical Field

[0001] The utility model relates to the technical field of plate rolling machines, and more specifically, to a thin-wall plate rolling machine with adjustable roller diameter. Background Art

[0002] The plate rolling machine is a shaping machine that performs continuous point bending on plates. It has the function of rolling plates of different shapes such as O-shaped, U-shaped, and multi-section R.

[0003] There are usually three rollers on a plate rolling machine, a single one on the top and two side by side on the bottom. When the upper roller rotates, it will move the plate, and the two lower rollers will naturally rotate due to the friction of the plate.

[0004] As the application of roller plate rolling becomes more and more widespread, when two specifications of plate rolling with the same rolling diameter but different wall thickness are required, it is necessary to readjust the spacing between the three rollers on the entire plate rolling machine. Generally, the spacing between the three rollers is adjusted by setting a motor to drive the two rollers below to rise and fall, because the two rollers below are generally not connected to the driving components, and the upper rollers rotate to carry the plate to move friction and drive the rotation of the two rollers below. Therefore, the installation structure and components of the two rollers below are simpler, and it is also more convenient to drive the two rollers below to rise and fall to adjust the spacing between the rollers.

[0005] However, since there are two rollers at the bottom, setting them up as movable and adjustable structures has greater uncertainty. During the lifting and adjustment process, a height difference is likely to occur between the two rollers, affecting the subsequent rolling operations. Utility Model Content

[0007] In a preferred embodiment, a fixing seat is installed in the middle of the base, a double-headed motor is installed on the fixing seat, and a rotating shaft is connected to each of the two ends of the double-headed motor.

[0021] Furthermore, the two ends of the upper roller shaft 3 are connected to the shaft rod 5, the shaft rod 5 is inserted into the sleeve 6 and rotates inside the sleeve 6. The sleeve 6 is located in the lifting hole 7 on the two bracket plates 1, and the sleeve 6 can be driven to move up and down in the lifting hole 7 by the lifting member to achieve the height adjustment of the upper roller shaft 3 to change the spacing between the roller shafts.

[0022] A fixing seat 9 is installed in the middle of the base 4, and a double-headed motor 10 is installed on the fixing seat 9. A rotating shaft 11 is connected to each of the two ends of the double-headed motor 10.

[0023] The rotating shaft 11 extends to both sides and passes through the two bracket plates 1. A first bearing 12 is sleeved at the connection between the rotating shaft 11 and the bracket plate 1. The first bearing 12 is embedded in the bracket plate 1.

[0024] Furthermore, the double-headed motor 10 is a servo motor, which can accurately control the number of revolutions thereof, and drive the rotating shafts 11 at both ends to rotate a certain number of circles and angles.

[0025] The lifting member includes a worm wheel 13 and a worm 14 located inside the protective cover 8, the worm wheel 13 is meshed with the worm 14, the worm 14 extends vertically and is connected to a connecting rod 15 at the top, the connecting rod 15 extends vertically upward and passes through the protective cover 8 to the top of the protective cover 8, a limiting tube 16 is sleeved on the outside of the connecting rod 15, the limiting tube 16 is located inside the protective cover 8, and the limiting tube 16 is fixed to the outer wall of the bracket plate 1;

[0026] The connecting rod 15 rotates in the limiting tube 16 and is installed on the outer wall of the bracket plate 1 through the limiting tube 16. The worm gear 13 is installed at the bottom end of the connecting rod 15 and meshes with the worm gear 13.

[0027] A thread is provided on the outer wall of the connecting rod 15 located above the protective cover 8, and a screw tube 17 matching the thread is sleeved on the top of the connecting rod 15, and the top of the screw tube 17 is fixedly connected to the bottom of the sleeve 6;

[0029] On the basis of the above, when the height of the upper roller shaft 3 needs to be adjusted, the double-headed motor 10 is controlled to work, and the rotating shaft 11 connected at both ends of the double-headed motor 10 rotates in the first bearing 12 on the two bracket plates 1, and drives the worm gear 13 located inside the protective cover 8 to rotate, and the worm gear 13 is engaged with the worm 14 at the bottom end of the connecting rod 15, driving the worm 14 to rotate to realize the rotation of the connecting rod 15 in the sleeve 6, and the top end of the connecting rod 15 is inserted in the screw tube 17, and the screw tube 17 is driven by the thread on the outer wall of the connecting rod 15 to move up and down outside the connecting rod 15, and according to the rotation direction of the connecting rod 15, the lifting and lowering of the sleeve 6 at the top end of the screw in the lifting hole 7 is realized, and the upper roller shaft 3 moves with the lifting and lowering of the sleeve 6 in the lifting hole 7.

[0030] Furthermore, the rotating shafts 11 on both sides are utilized to simultaneously drive the worm gears 13 in the lifting members on both sides to work, so as to realize a method of driving both ends of the upper roller shaft 3 to be lifted and lowered simultaneously, which can realize a stable lifting and lowering adjustment of the upper roller shaft 3. Compared with the method of adjusting the lower roller shaft 2, the lifting and lowering adjustment method of the upper roller shaft 3 is more stable, and the problem of height difference and offset between the roller shafts due to spacing adjustment is reduced.

[0031] The end of the sleeve 6 extends a distance to the outside of the bracket plate 1, and the shaft 5 is longer than the sleeve 6 and extends a distance outward from the end of the sleeve 6;

[0032] Furthermore, the shaft 5 extends outward for a certain distance, and a driving member for driving the shaft 5 can be installed at the end of the shaft 5, so as to drive the shaft 5 to rotate in the sleeve 6 to drive the upper roller 3 to rotate. The driving member forms a whole with the shaft 5 and the upper roller 3, and rises and falls with the lifting and lowering movement of the upper roller 3, thereby simplifying the overall structure of the equipment.
