Description

Technical Field

[0001] The present invention relates to the technical field of plate rolling machines, and particularly relates to a four-star roll plate rolling machine for the production of wind power tower barrel sections. Background Art

[0002] The four-star roll plate rolling machine is a heavy industrial equipment dedicated to rolling thick steel plates into cylindrical workpieces, and is particularly widely used in the manufacture of large structures such as wind power towers and pressure vessels. Its core function is to achieve precise bending and forming of steel plates through the coordinated action of multiple rolls. The four-star roll plate rolling machine is provided with two parts: a correction and conveying device and a roll system layout. The correction and conveying device is used for conveying and position correction of the steel plate raw material, and the roll system layout is used for extruding and bending the steel plate and curling it into a cylinder.

[0003] When the steel plate is curled, the steel plate slides on the correction and conveying device. When the steel plate slides into the curling part, the steel plate is bent by the extrusion of the four rolls, and by driving the steel plate to rotate, the steel plate is bent after passing between the four rolls and gradually forms a cylinder. However, when the steel plate starts to be extruded and bent, the part of the steel plate on the correction and conveying device will warp. When the existing four-star roll plate rolling machine processes the steel plate, the part of the steel plate close to the roll system layout warps and separates from the correction and conveying device. When there are unevenness, inconsistent plasticity or positions where the steel plate slips on the surface of the steel plate, it is easy for the steel plate to shift or partially deflect, which will cause the angle of the part of the steel plate entering the roll system layout to deflect, and then lead to the problem that the two ends of the curled cylindrical workpiece are misaligned. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a four-star roll plate rolling machine for the production of wind power tower barrel sections to solve the problem that the steel plate is prone to shift and tilt during extrusion and curling in the prior art as put forward in the background art.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 to 7, A four-star roll bending and plate rolling machine for the production of wind power tower barrel sections, including a frame 1, on which a roll system layout 2 is provided. A straightening and conveying device is fixedly connected to the frame 1. The straightening and conveying device further includes a first base 3, a second base 4, an arc lifting mechanism, a following straightening frame 6 and a pressing and adjusting mechanism. The first base 3 is fixedly connected to the frame 1. The second base 4 is arranged on the side of the first base 3 away from the frame 1. A straightening assembly is arranged on the side of the second base 4 away from the first base 3. The straightening assembly includes a pushing groove 28 and a pushing block 29. When the steel plate moves towards the roll system layout 2, the pushing block 29 slides in the pushing groove 28 to push the steel plate and correct the position of the steel plate. When the steel plate is rolled into a circle in the roll system layout 2, it separates from the pushing block 29. A driving cylinder or other driving device is arranged in the pushing groove 28 to push the pushing block 29 to move. The straightening assembly is a component for pushing and straightening the steel plate on the existing plate rolling machine. The arc lifting mechanism is rotatably connected to the first base 3 and slidably connected to the second base 4. The arc lifting mechanism is used to lift the warped steel plate. A placing bracket 5 is fixedly connected between the first base 3 and the second base 4. The placing bracket 5 is used to support when the arc lifting mechanism does not lift the warped steel plate. The following straightening frame 6 is slidably arranged on the side of the arc lifting mechanism close to the first base 3. The following straightening frame 6 is used to keep supporting and fixing the steel plate when the steel plate warps. An extension rod is arranged above the side of the following straightening frame 6 close to the steel plate to prevent the height of the warped steel plate from being too high and limit the steel plate. The pressing and adjusting mechanism is fixedly arranged on the first base 3 and is detachably connected to the following straightening frame 6. The pressing and adjusting mechanism is used to drive the following straightening frame 6 to push and straighten the steel plate. A support groove 27 for supporting the third roller 18 is fixedly connected to the placing bracket 5. The placing bracket 5 is used to support the sliding arm 12. When the output end of the first driving cylinder 8 shortens, the sliding arm 12 contacts the placing bracket 5 for support.

[0017] Please refer to Figures 1 to 3 , Preferably, an extrusion track 7 and a first driving cylinder 8 are arranged on the second base 4. The extrusion track 7 is arranged in an arc shape and is arranged on the side of the second base 4 close to the first base 3. The lower end of the extrusion track 7 is fixedly connected to the second base 4. The distance between the upper end of the extrusion track 7 and the first base 3 is less than the distance between the lower end and the first base 3. The first driving cylinder 8 is rotatably connected to the side of the second base 4 close to the first base 3. When the rotating shaft 11 slides upward on the extrusion track 7, it gradually approaches the first lifting frame 9, so that the first lifting frame 9 and the second lifting frame 10 slide towards each other. At this time, the third roller 18 is pushed upward by the extrusion and lifting assembly.

[0018] Please refer to Figures 1 to 5, Further, the arc lifting mechanism includes a first lifting frame 9, a second lifting frame 10 and an extrusion lifting assembly. The first lifting frame 9 is rotatably connected to the first base 3. A rotating shaft 11 is fixedly connected to the second lifting frame 10. The rotating shaft 11 is slidably connected to the extrusion track 7. The side of the rotating shaft 11 away from the extrusion track 7 is rotatably connected to the output end of the first driving cylinder 8. A sliding arm 12 is fixedly connected to the side of the first lifting frame 9 close to the second lifting frame 10. An arm 13 is fixedly connected to the end of the second lifting frame 10 close to the first lifting frame 9. The arm 13 is slidably connected to the sliding arm 12. Both sides of the extrusion lifting assembly are respectively rotatably connected to the first lifting frame 9 and the second lifting frame 10. The extrusion lifting assembly includes a first roller 14, a second roller 15, a first extrusion rod 16, a second extrusion rod 17 and a third roller 18. The first roller 14 is rotatably connected to the side of the first lifting frame 9 close to the sliding arm 12. The second roller 15 is rotatably connected to the side of the second lifting frame 10 close to the arm 13. The first extrusion rod 16 is rotatably connected to the first roller 14. The second extrusion rod 17 is rotatably connected to the second roller 15. Both the first extrusion rod 16 and the second extrusion rod 17 are rotatably connected to the third roller 18. The third roller 18 is arranged between the first roller 14 and the second roller 15. The first lifting frame 9 and the second lifting frame 10 are slidably connected and kept parallel through the arm 13 and the sliding arm 12. When the first lifting frame 9 and the second lifting frame 10 rotate upward under the action of the first driving cylinder 8, the second lifting frame 10 slides towards the first lifting frame 9, and at the same time, the first extrusion rod 16 and the second extrusion rod 17 are pushed to push the third roller 18 away from the arm 13, so that the first roller 14, the second roller 15 and the third roller 18 form an arc to support the warped steel plate.

[0019] Please refer to Figures 3 to 5 , As a further solution of the present application, a sliding frame 19 is fixedly connected to the first lifting frame 9. The following correction frame 6 is slidably arranged on the sliding frame 19. An extrusion wheel 20 is rotatably connected to the side of the following correction frame 6 close to the steel plate. The center of the following correction frame 6 is arranged in a penetrating shape. A pin 21 is rotatably connected to the center of the sliding frame 19. A limiting tooth 22 matched with the pin 21 is arranged on the following correction frame 6. When the pin 21 rotates and is matched with the limiting tooth 22, the following correction frame 6 is fixed on the sliding frame 19. When the first lifting frame 9 rotates, the sliding frame 19 rotates accordingly, so that the following correction frame 6 rotates with the first lifting frame 9 to always keep supporting the steel plate. At the same time, since the steel plate is in an inclined state after warping, the inclined following correction frame 6 can better support the steel plate. After the fixing frame 23 is not in contact with the pin 21, the pin 21 rotates and falls into the limiting tooth 22, so that the following correction frame 6 is fixed and cannot slide. Furthermore, when supporting the steel plate, the following correction frame 6 remains in a fixed state. After the support is completed, the fixing frame 23 contacts and supports the pin 21, then the support pin 21 rotates and separates from the limiting tooth 22, which is convenient for pushing and correcting the steel plate again.

[0020] Please refer to Figures 4 to 7On the basis of the above scheme, the extrusion adjustment mechanism includes a fixed frame 23, a driving cylinder 25 and an L-shaped slide 26. The fixed frame 23 is fixedly connected to the base 3. A push arm 24 capable of contacting the pin 21 is provided on the upper side of the fixed frame 23. The driving cylinder 25 is fixedly installed on the fixed frame 23. The L-shaped slide 26 is slidably connected to the upper side of the fixed frame 23. The L-shaped slide 26 is fixedly connected to the output end of the driving cylinder 25. The L-shaped slide 26 is detachably connected to the follow-up correction frame 6. The follow-up correction frame 6 and the L-shaped slide 26 are both tilted. When the lifting frame 9 is placed toward the bracket 5 rotates, the fixed frame 23 and the L-shaped slide 26 gradually cooperate with the following correction frame 6. By setting the L-shaped slide 26 and the following correction frame 6 in an inclined manner, when the lifting frame 1 9 rotates, the fixed frame 23 and the L-shaped slide 26 will not collide or squeeze with the following correction frame 6 when they dock with each other, and thus avoid interlacing. At the same time, the L-shaped slide 26 can be inserted into the groove on the following correction frame 6. When the output end of the driving cylinder 25 drives the L-shaped slide 26 to slide, it can drive the following correction frame 6 to slide on the fixed frame 23, pushing the steel plate for correction, and jointly pushing the steel plate with the correction assembly on the base 2 4 to correct.

[0021] In this embodiment, a roller is rotatably provided on the base 1 3, and a plurality of rollers are rotatably connected to the base 2 4. The roller has the same diameter as roller 14 and roller 2 15. The diameter of roller 3 18 is slightly smaller than roller 14 and roller 2 15. When roller 3 18 is in the support groove 27, the axis of roller 3 18 is slightly higher than roller 14 through the support of the support groove 27, so that roller 3 18 also supports the steel plate, so that the extrusion rod 16 and the extrusion rod 2 17 remain in an inclined state. When the lifting frame 1 9 and the lifting frame 2 10 slide toward each other, it is convenient to support roller 3 18 upward.

[0022] To sum up, when the four-star roller rolling machine for producing wind turbine tower sections rolls the steel plate, the steel plate is conveyed to the rollers on base 1 3 and base 2 4, and the follow-up correction frame 6 pushed by the output end of the correction component and the drive cylinder 2 25 pushes the steel plate to correct it. When the steel plate enters the roller system layout 2 and is squeezed, the steel plate tilts up. At this time, the output end of the drive cylinder 1 8 extends to push the rotating shaft 11 to slide on the extrusion track 7. At the same time, the lifting frame 2 10 slides toward the lifting frame 1 9, squeezing the extrusion rod 2 17 and the extrusion rod 1 16, and supporting the roller 3 18 upward. The roller 14, roller 2 15 and roller 3 18 form an arc. At the same time, the follow-up correction frame 6 is separated from the fixed frame 23, and the extrusion wheel 20 provides limited support for the steel plate.

[0023] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
