Description

Technical Field

[0001] The present invention relates to the technical field of plate rolling machines, and in particular to a four-star roller round plate rolling machine for producing wind turbine tower sections. Background Art

[0002] The four-star roller circular plate rolling machine is a heavy-duty industrial equipment specially used for rolling thick steel plates into cylindrical workpieces. It is especially widely used in the manufacture of large structures such as wind turbine towers and pressure vessels. Its core function is to achieve precise bending and forming of steel plates through the coordinated action of multiple rollers. The four-star roller circular plate rolling machine is equipped with two parts: a correction conveying device and a roller layout. The correction conveying device is used to convey the steel plate raw materials and correct their position, and the roller layout is used to extrude, bend and curl the steel plates into cylinders.

[0003] When the steel plate is curled, the steel plate slides on the correction conveyor. When the steel plate slides into the curling part, the steel plate is bent by the squeezing of the four rollers, and the steel plate is driven to rotate, so that the steel plate is bent after passing between the four rollers, gradually forming a cylinder. However, when the steel plate begins to be squeezed and bent, the part of the steel plate on the correction conveyor will warp. When the existing four-star roller rolling machine processes the steel plate, the part of the steel plate close to the roller layout is warped and separated from the correction conveyor. When the surface of the steel plate is uneven, the shape is inconsistent, or there is a position where it slips with the roller, it is easy for the steel plate to shift or partially deflect, which will cause the part of the steel plate entering the roller layout to have an angular deflection, which will lead to the problem of misalignment of the two ends of the cylindrical workpiece formed by the curling.

The extrusion adjustment mechanism is fixedly arranged on the base 1 3, and the extrusion adjustment mechanism is detachably connected to the following correction frame 6. The extrusion adjustment mechanism is used to drive the following correction frame 6 to push the steel plate for correction. The placement bracket 5 is fixedly connected with a support groove 27 for supporting the roller three 18. The placement bracket 5 is used to support the sliding arm 12. When the output end of the driving cylinder 1 8 is shortened, the sliding arm 12 contacts the placement bracket 5 for support.

[0025] See also Figures 1 to 3 Preferably, an extrusion track 7 and a drive cylinder 1 8 are provided on the base 2 4. The extrusion track 7 is arranged in an arc shape.

The drive cylinder 1 8 is rotatably connected to the side of the base 2 4 close to the base 1 3. When the rotating shaft 11 is set to slide upward on the extrusion track 7, it gradually approaches the lifting frame 1 9, so that the lifting frame 1 9 and the lifting frame 2 10 slide in opposite directions. At this time, the roller 3 18 is pushed upward by the extrusion lifting assembly.

[0026] See also Figures 1 to 5Furthermore, the arc-shaped lifting mechanism includes a lifting frame 19, a lifting frame 210 and an extrusion lifting assembly. The lifting frame 19 is rotatably connected to the base 13. The lifting frame 210 is fixedly connected with a rotating shaft 11. 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 driving cylinder 18.

When the lifting frame one 9 and the lifting frame two 10 rotate upward under the action of the driving cylinder one 8, the lifting frame two 10 slides toward the lifting frame one 9, and at the same time pushes the squeezing rod one 16 and the squeezing rod two 17 to push the roller three 18 away from the support arm 13, so that the roller one 14, the roller two 15 and the roller three 18 form an arc to support the raised steel plate.

[0027] See also Figures 3 to 5 As a further solution of the present application, a sliding frame 19 is fixedly connected to the lifting frame 9, and the following correction frame 6 is slidingly arranged on the sliding frame 19.

The following correction frame 6 is provided with a limiting tooth 22 that cooperates with the pin 21. When the pin 21 rotates and cooperates with the limiting tooth 22, the following correction frame 6 is fixed to the sliding frame 19. When the lifting frame 9 rotates, the sliding frame 19 rotates with it, so that the following correction frame 6 is fixed to the sliding frame 19. The following correction frame 6 rotates with the lifting frame 9, always maintaining support for the steel plate. At the same time, since the steel plate is in an inclined state after being tilted, the inclined following correction frame 6 can better support the steel plate. After the fixing frame 23 is no longer 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, so that when supporting the steel plate, the following correction frame 6 remains in a fixed state. After the support ends, the fixing frame 23 contacts and supports the pin 21, and the supporting pin 21 rotates and separates from the limiting tooth 22, so that the steel plate can be pushed and corrected again.

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.

[0029] 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.

[0030] 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.
