DETAILED DESCRIPTION

[0027] See also Figures 1 to 4 As shown, the embodiment of the present application provides a steel pipe and flat steel bending device, including a roller 5 and a roller frame 4. The roller 5 is rotatably arranged on the roller frame 4. A connecting member 6 is arranged on the roller 5. The connecting member 6 is a U-shaped structure. Both ends of the connecting member 6 are respectively welded on both sides of the roller 5. A force adding rod 7 is connected to the side of the connecting member 6 away from the roller 5. The force adding rod 7 facilitates the rotation of the roller 5 and plays a labor-saving role. A limiting member 10 is also arranged on the roller 5. The limiting member 10 is arranged opposite to the connecting member 6. A gap is left between the limiting member 10 and the roller 5 for the flat steel or steel pipe to pass through. The limiting member 10 is used to clamp the flat steel or steel pipe, so that when the roller 5 rotates to drive the limiting member 10 to rotate, the steel pipe or flat steel located between the limiting member 10 and the roller 5 can be bent. The roller 5 has an outer edge portion 51 and an inner edge portion 52. The inner edge portion 52 is used to bend the flat steel, and the outer edge portion 51 is used to bend the steel pipe.

[0028] It should be noted that the diameters of the outer edge portion 51 and the inner edge portion 52 are both larger than the diameter of the roller 5, and the diameter of the outer edge portion 51 is larger than the diameter of the inner edge portion 52. The outer edge portion 51 includes two oppositely disposed first cylindrical edges, and the inner edge portion 52 includes two oppositely disposed second cylindrical edges. The inner side surfaces of the first cylindrical edge and the second cylindrical edge are both arc surfaces inclined from the outside to the inside.

[0029] In the above scheme, by providing a roller 5 and a limit piece 10 with an outer edge portion 51 and an inner edge portion 52, and passing the flat steel through the gap so that the flat steel is located in the inner edge portion 52, or passing the steel pipe through the gap so that the steel pipe is located in the outer edge portion 51, the force rod 7 is rotated to rotate the roller 5, thereby bending the flat steel or the steel pipe. Compared with the method of purchasing finished products, the cost is reduced, the efficiency of the processing and bending is improved, and the extension of the construction period is avoided.

[0030] In some possible implementations, see Figure 1 and Figure 2As shown, a square tube 2 is provided at the bottom of the roller frame 4, and a storage plate 3 is fixedly connected to one side of the square tube 2 in the length direction. Two symmetrical first vertical plates 12 are provided on the storage plate 3 along its length direction, and two symmetrical second vertical plates 13 are provided between the two first vertical plates 12 along its length direction. The square tube 2 and the storage plate 3 are horizontally arranged, and the two second vertical plates 13 are matched with the inner edge portion 52, so that when the flat steel is located between the two second vertical plates 13, if the flat steel is pushed, the flat steel will be clamped in the inner edge portion 52, and the two first vertical plates 12 are used to place and position the steel pipe so that the steel pipe is in the center position. If the steel pipe is located between the two first vertical plates 12, if the steel pipe is pushed, the steel pipe will be clamped in the outer edge portion 51.

[0031] In some possible implementations, see Figure 1 and Figure 2 As shown, the height dimension of the second vertical plate 13 is smaller than the height dimension of the first vertical plate 12, so that the steel pipe can be stably clamped between the two first vertical plates 12. The two first vertical plates 12 are arranged corresponding to the inner edge portion 52, and the two second vertical plates 13 are arranged corresponding to the outer edge portion 51.

[0032] In some possible implementations, see Figure 3 and Figure 4 As shown, the two ends of the limit member 10 are fixedly connected to the two sides of the roller 5 respectively, and two limit plates 11 are arranged at the inner bottom of the limit member 10. The two limit plates 11 are arranged opposite to each other, and the two limit plates 11 are arranged corresponding to the inner edge portion 52. The length dimension between the two limit plates 11 is equal to the width dimension of the inner edge portion 52.

[0033] In some possible implementations, see Figure 3 and Figure 4 As shown, a limiting slot 9 is provided on the square tube 2 , and a limiting member 10 is detachably disposed in the limiting slot 9 .

[0034] It should be noted that when the roller 5 rotates clockwise, the rotation of the roller 5 drives the limit member 10 to rotate, so that the limit member 10 is disengaged from the limit slot 9. When the roller 5 rotates counterclockwise, the rotation of the roller 5 drives the limit member 10 to rotate in the opposite direction, so that the limit member 10 is engaged in the limit slot 9.

[0035] In some possible implementation schemes, the roller 5 is connected to the roller frame 4 via a rotating shaft, a torsion spring (not shown in the figure) is sleeved on the rotating shaft, and two ends of the torsion spring are respectively connected to the roller 5 and the roller frame 4.

[0036] It should be noted that after the force-adding rod 7 is rotated to complete the bending of the steel pipe or flat steel, the torsion spring is tightened by force, and the elastic potential energy of the torsion spring increases. After the force-adding rod 7 is released, the roller 5 rotates in the opposite direction under the action of the elastic force of the torsion spring. When the limit member 10 abuts against the limit slot 9, the roller 5 stops rotating, and the force-adding rod 7 is in a vertical state at this time.

[0037] In some possible implementations, see Figure 1 As shown, the steel pipe and flat steel bending device provided in the embodiment of the present application also includes a fixed frame plate 1, which has an installation cavity, and the square tube 2 and the storage plate 3 are arranged in the installation cavity. The fixed frame plate 1 is used to increase the force-bearing area between the square tube 2 and the storage plate 3 and the ground, so that the bending of the steel pipe or flat steel is more stable, and the fixed frame plate 1 is set on the ground by bolts on all sides.

[0038] In some possible implementations, see Figure 1 and Figure 2 As shown, a handle 8 is provided at one end of the force-adding rod 7 away from the connecting piece 6 , and the handle 8 is convenient for the staff to rotate the force-adding rod 7 .

[0039] By providing a roller 5 and a limit piece 10 with an outer edge 51 and an inner edge 52, and passing a flat steel through a gap so that the flat steel is located in the inner edge 52, or passing a steel pipe through the gap so that the steel pipe is located in the outer edge 51, and rotating the force rod 7 to rotate the roller 5, the flat steel or the steel pipe is bent. Compared with the method of purchasing finished products, the cost is reduced, the efficiency of the bending process is improved, and the extension of the construction period is avoided.

[0040] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
