Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of prism tube forming, and more specifically, to a prism tube forming device for scaffolding. Background Art

[0002] A scaffold is a temporary support structure used in building construction to support workers, tools, and materials. It is usually composed of steel pipes, connectors, and scaffold boards. When in use, the scaffold is fixedly connected through connectors, and scaffold boards are placed for workers to step on. The scaffold provides a high-altitude operation platform for workers to ensure construction safety and efficiency.

[0003] At both ends of the steel pipes used in the scaffold, prism tubes can be connected to connect with other steel pipes. The two ends of the prism tube are set as polygons. Through this polygon setting, inserting a polygonal steel pipe into the prism tube can prevent the steel pipe from rotating. At the same time, the polygonal prism tube can also provide a clear card position direction for quick alignment and installation. At the same time, the bearing capacity of the prism tube is relatively high, which can improve the supporting force for the connected steel pipes. A through hole is provided in the center of the prism tube for passing through the steel pipe for fixation. In the existing process of forming and processing the prism tube, a round tube is manually held, and both ends are respectively inserted into the forming device for forming. However, the processing efficiency by manual operation is relatively low, and during processing, sometimes the angle between the through hole in the center of the prism tube and the formed polygon is deviated, so that when installing, the direction of the through hole may be deviated after the prism tube is positioned, causing difficulties in installation and use.

[0008] On one side of the flipping frame away from the docking seat, there is a loading plate. The loading plate is inclined. The arc-shaped rod is C-shaped. The opening direction of the arc-shaped rod faces the flipping frame. The upper part of the opening of the arc-shaped rod is aligned with the loading plate.

[0009] The arc-shaped rod includes a first arc segment, a second arc segment, and a third arc segment. The first arc segment is circular arc-shaped. The second arc segment is fixedly connected to the first arc segment. The third arc segment is circular arc-shaped. The third arc segment is arranged on the side of the loading plate.

The radius of the third arc segment is greater than that of the first arc segment. The rotating shaft is arranged at the center of the circle of the first arc segment.

[0010] The cylindrical frame is provided with positioning bumps. The positioning bumps are detachably connected to the through holes.

[0022] In addition, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0023] Embodiment 1 As Figures 1 to 7 shown, it shows a forming device for a prism tube used in a scaffold in an embodiment of the present disclosure, including a blank 1, a through hole 2 is provided on the blank 1, and further includes a docking seat 3, a driving cylinder 4, an arc-shaped rod and a flipping mechanism. There are two docking seats 3, and a forming device 5 is slidably connected to each of the two docking seats 3. The two forming devices 5 are arranged oppositely. The driving cylinder 4 is fixedly connected to the docking seat 3, and the output end of the driving cylinder 4 is fixedly connected to the forming device 5. There are multiple arc-shaped rods, and the arc-shaped rods are arranged between the two docking seats 3. The arc-shaped rods are in contact with the blank 1, and a runner mechanism is fixedly arranged on the arc-shaped rods. The runner mechanism is used to drive the blank 1 to rotate. The flipping mechanism is arranged between the two docking seats 3, and the arc-shaped rod is sleeved outside the flipping mechanism. The flipping mechanism is used to drive the blank 1 to move between the two forming devices 5. The two forming devices 5 slide on the docking seat 3 through the driving cylinder 4. When the blank 1 is moved between the two forming devices 5 through the flipping mechanism, at this time, the two forming devices 5 slide oppositely, and the blank 1 is sleeved on the expansion assembly 19. The expansion assembly 19 is set as multiple clamping members slidably arranged on the forming device 5. Then, the expansion cone 20 is pushed into the expansion assembly 19, so that the multiple clamping members expand and slide outwards, so that the inner parts of both ends of the blank 1 are subjected to expansion extrusion and become polygonal. When only one end of the blank 1 needs to be processed, only one forming device 5 can be controlled for processing.

[0024] As Figures 1 to 5As shown, the flipping mechanism includes a flipping frame 6, a first motor 7, and a deflection wheel assembly. The flipping frame 6 is arranged between two docking seats 3. The first motor 7 is fixedly installed on the flipping frame 6. The deflection wheel assembly is rotatably connected to the flipping frame 6. The arc-shaped rod is sleeved on the deflection wheel assembly. The deflection wheel assembly is drivingly connected to the output end of the first motor 7. The deflection wheel assembly is used to drive the blank 1 to rotate to a position aligned with the forming device 5. The deflection wheel assembly includes a rotating shaft 8, a cylindrical frame 9, and a shielding frame 10. The rotating shaft 8 is rotatably connected to the flipping frame 6. A plurality of cylindrical frames 9 are arranged in a circle on the rotating shaft 8. The cylindrical frame 9 is arranged in a C shape. The cylindrical frame 9 is detachably connected to the blank 1. The cylindrical frame 9 is composed of a plurality of C-shaped plates. The shielding frame 10 is connected to the plates on both sides. There are a plurality of shielding frames 10. The shielding frame 10 is arranged between two adjacent cylindrical frames 9. The two ends of the shielding frame 10 are respectively connected to the two cylindrical frames 9. A plurality of shielding frames 10 are respectively arranged on both sides of the rotating shaft 8. A plurality of shielding frames 10 are arranged on both sides of the arc-shaped rod. The blank 1 on the loading plate 11 slides to contact the shielding frame 10 under the action of gravity. When the cylindrical frame 9 rotates to be aligned with the loading plate 11, the blank 1 rolls into the cylindrical frame 9. Driven by the rotating mechanism, after the through hole 2 is aligned with the positioning convex block 15, the rotating shaft 8 drives the blank 1 to rotate to be aligned with the forming device 5 and then the rotating shaft 8 stops rotating. At this time, the forming device 5 processes the blank 1. After processing, the output end of the driving cylinder 4 shortens, so that the forming device 5 is separated from the blank 1. At this time, the blank 1 is processed and rolls away from the cylindrical frame 9 at the opening of the arc-shaped rod as the rotating shaft 8 rotates. When the rotating shaft 8 rotates, the shielding frame 10 can support the blank 1 on the loading plate 11 to prevent the blank 1 from rolling downwards.

[0025] As Figures 3 to 5 shown, on the side of the flipping frame 6 away from the docking seat 3, there is a loading plate 11. The loading plate 11 is arranged obliquely. The arc-shaped rod is arranged in a C shape. The opening direction of the arc-shaped rod faces the flipping frame 6. The upper part of the opening of the arc-shaped rod is aligned with the loading plate 11. The blank 1 on the loading plate 11 can roll into the cylindrical frame 9 at the arc section three 14.

[0026] As Figures 4 to 7As shown in the figure, the arc-shaped rod includes arc section one 12, arc section two 13, and arc section three 14. Arc section one 12 is set as a circular arc. Arc section two 13 is fixedly connected to arc section one 12. Arc section three 14 is set as a circular arc. Arc section three 14 is arranged on the side of the loading plate 11. The rotating wheel mechanism is fixedly arranged on arc section two 13. Arc section three 14 and arc section one 12 are concentrically arranged. The radius of arc section three 14 is greater than that of arc section one 12. The rotating shaft 8 is arranged at the center of the circle of arc section one 12. After the blank 1 enters the cylindrical frame 9, the blank 1 contacts arc section three 14. After the through hole 2 is docked with the positioning convex block 15, the blank 1 contacts arc section one 12. After the blank 1 enters the cylindrical frame 9 on the loading plate 11, assuming that the through hole 2 is not aligned with the positioning convex block 15, at this time, as the rotating shaft 8 rotates, arc section three 14 contacts the blank 1 to prevent the blank 1 from leaving the cylindrical frame 9. When the blank 1 rotates to arc section two 13, the rotating wheel mechanism drives the blank 1 to rotate. After the through hole 2 is aligned with the positioning convex block 15, the blank 1 is completely attached to the cylindrical frame 9. At this time, as the rotating shaft 8 rotates, the blank 1 is attached to arc section one 12 to prevent the blank 1 from rotating in the cylindrical frame 9.

[0027] As Figures 3 to 5 shown in the figure, the cylindrical frame 9 is provided with a positioning convex block 15. The positioning convex block 15 is detachably connected to the through hole 2. After the blank 1 enters the cylindrical frame 9, when the through hole 2 is not aligned with the positioning convex block 15, the blank 1 cannot completely enter the cylindrical frame 9 and be attached to it. After the rotating wheel mechanism drives the blank 1 to rotate until the positioning convex block 15 enters the through hole 2, the blank 1 completely enters the cylindrical frame 9. At this time, when the blank 1 is subjected to forming processing, the blank 1 will not rotate, and at the same time, the angle of the blank 1 during forming can be fixed, so that the angle between the polygon and the through hole 2 is fixed.

[0028] As Figures 5 to 7 shown in the figure, the rotating wheel mechanism includes a connecting frame 16, roller wheels 17, and a second motor 18. The connecting frame 16 is fixedly connected to arc section two 13. A plurality of roller wheels 17 are provided. The plurality of roller wheels 17 are rotatably connected to the connecting frame 16. The plurality of roller wheels 17 are drivingly connected. The second motor 18 is fixedly installed on the connecting frame 16. The output end of the second motor 18 is drivingly connected to one of the roller wheels 17. In this embodiment, three roller wheels 17 are provided, and the three roller wheels 17 are drivingly connected to each other in pairs, so that the three roller wheels 17 rotate at the same speed and in the same direction. The second motor 18 drives the roller wheels 17 to rotate. After the blank 1 contacts the roller wheels 17, the roller wheels 17 drive the blank 1 to rotate. After the through hole 2 is aligned with the positioning convex block 15, the roller wheels 17 are separated from the blank 1.

[0029] In some examples, a plurality of blanks 1 are placed on the loading plate 11. The blank 1 contacts the shielding frame 10. The output end of the first motor 7 drives the rotating shaft 8 to rotate. When the cylindrical frame 9 is aligned with the loading frame, the blank 1 rolls into the cylindrical frame 9. When the blank 1 contacts the roller 17, the output end of the second motor 18 drives the roller 17 to rotate. The roller 17 drives the blank 1 to rotate so that the through hole 2 is aligned with the positioning projection 15. The blank 1 continues to rotate and contacts the first arc segment 12. When the blank 1 rotates to be aligned with the expansion assembly 19, the output end of the driving cylinder 4 extends to push the expansion assembly 19 into the blank 1. The expansion cone 20 extends into the expansion assembly 19 to extrude the blank 1. After the forming is completed, the driving cylinder 4 shortens to pull the forming device 5 away from the blank 1. The processed blank 1 rotates with the rotating shaft 8. When the blank 1 separates from the first arc segment 12, it rolls out of the cylindrical frame 9.

[0030] Embodiment II A positioning projection 15 can be arranged in the cylindrical frame 9 to rotate around the cylindrical frame 9. By setting the angle between the positioning projection 15 and the cylindrical frame 9, the angle between the prism tube polygon and the through hole 2 can be adjusted.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not restrictive. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
