[0002] Pipelines are often fixed around the pipe during installation using arc-shaped rods. These fixing rods are mostly made of round metal materials. During the manufacturing process, the middle section usually needs to be bent to meet the angle requirements for installation around the pipe. Traditional bending methods are mostly done manually with tools such as vises and manual levers. This is not only laborious and inaccurate in terms of angle, but also prone to uneven stress during multiple bending processes, making it unsuitable for mass production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a bending device for a pipe fixing rod, comprising: a housing 1; a seat plate 2 is fixedly installed on the top of the housing 1, one end of the seat plate 2 is suspended, and a rectangular first stop block 3 and a semi-circular second stop block 4 are fixedly installed on the top of the seat plate 2 respectively, the straight end of the first stop block 3 and the arc end of the second stop block 4 face each other, and the gap between them is used to place the pipe fixing rod; Two symmetrical movable plates 5 are rotatably connected between the suspended end of the seat plate 2 and the machine box 1 via a rotating shaft. The top of the movable plate 5 is provided with an adjustable bending mechanism along the length direction. The bending mechanism includes a concave wheel 9, which is used to assist in the bending operation of the pipe fixing rod. A mounting plate 10 is fixedly installed on the top of the chassis 1. A second bolt 11 is threadedly connected to the top of the mounting plate 10. One end of the second bolt 11 faces and is directly opposite the gap between the straight end of the first stop 3 and the arc end of the second stop 4, which is used for positioning when the pipe fixing rod is placed. The combination of the chassis 1, base plate 2, first stop 3, second stop 4, moving plate 5 and bending mechanism enables stable placement and precise bending of the pipe fixing rod. The first stop 3 and second stop 4 of the base plate 2 are used for limiting and positioning, while the moving plate 5 drives the bending mechanism to flexibly bend the pipe fixing rod through the rotation of the shaft. The second bolt 11 provides adjustable limiting force to ensure consistent placement.

[0016] More preferably, the rotating shaft end of the movable plate 5 extends into the housing 1 and is fixedly connected to a gear 15. A telescopic cylinder 12 is fixedly provided on the outer wall of the housing 1 corresponding to each movable plate 5. A rack 13 that engages with the gear 15 is fixedly connected to one end of the telescopic shaft of the telescopic cylinder 12. By setting up a structure of gear 15, telescopic cylinder 12, and rack 13, the automatic driving bending of the moving plate 5 is realized. The rotating shaft end of the moving plate 5 is connected to gear 15, and the telescopic shaft of telescopic cylinder 12 pushes rack 13 to mesh with gear 15, thereby driving the moving plate 5 to rotate, realizing the mechanized bending of the pipe fixing rod, improving bending accuracy and operating efficiency, and reducing manual labor intensity.

[0017] In a further preferred embodiment, a sliding sleeve 14 is fixedly provided on the inner wall of the housing 1, and the end of the rack 13 away from the telescopic cylinder 12 slides through the sliding sleeve 14 for linear guidance of the rack 13. The tooth surface of the rack 13 passes through the gear 15 and meshes with the adjacent gear 15. By fixing the sliding sleeve 14 to the inner wall of the housing 1, the end of the rack 13 away from the telescopic cylinder 12 is slidably inserted into the sliding sleeve 14, which provides linear guidance for the movement of the rack 13, prevents the rack 13 from deviating or shaking during transmission, and ensures that the rack 13 and the gear 15 mesh smoothly and reliably, thereby improving the stability of the transmission force and the service life of the equipment when the pipe fixing rod is bent.

[0018] In a further preferred embodiment, the bending mechanism also includes a groove 6 formed on the outer wall of the movable plate 5, and a slider 7 is slidably connected in the groove 6. A concave wheel 9 is rotatably connected to the top of the slider 7, and the pipe fixing rod is engaged by the groove of the concave wheel 9. A bending mechanism is formed by creating a groove 6 on the outer wall of the movable plate 5 and sliding it to connect the slider 7, allowing the concave wheel 9 to rotate and connect to the top of the slider 7. The groove of the concave wheel 9 fits against the outer wall of the pipe fixing rod. By adjusting the position of the concave wheel 9 through the slider 7, the stress on the pipe fixing rod is evenly distributed at the stress point, reducing stress concentration during bending deformation and ensuring a smooth and accurate bending shape.

[0019] More preferably, one end of the movable plate 5 is threadedly connected to a first bolt 8, one end of the first bolt 8 passes through the slide groove 6 and is rotatably connected to the slider 7, which is used to adjust the position of the slider 7 to change the spacing of the concave wheel 9; By threading a first bolt 8 to one end of the movable plate 5 and rotating the end of the first bolt 8 to connect to the slider 7, the position of the slider 7 can be precisely adjusted. The spacing of the concave rollers 9 can be adjusted according to the length of the pipe fixing rod and the bending angle, thereby flexibly changing the bending point position, achieving the effect of multi-specification adaptation and bending radius control, and improving the versatility of the equipment.

[0020] One specific application of this embodiment is: adjusting the second bolt 11 according to the length of the pipe fixing rod, using its end to assist the positioning of the pipe fixing rod, performing batch bending processing, and making the rod body less prone to slippage during bending. The pipe fixing rod to be bent is placed horizontally in the gap between the first stop 3 and the second stop 4, so that its two ends contact the groove of the concave wheel 9 respectively, and at the same time abut against the second bolt 11 for positioning. Then, the telescopic cylinder 12 can be connected to a foot-operated control switch to control the telescopic shaft to push the rack 13 to move, and at the same time drive the gear 15 to rotate. The rotating shaft drives the moving plate 5 to rotate around the shaft. The concave wheel 9 on the moving plate 5 rotates synchronously to apply bending force to the pipe fixing rod. After the bending angle reaches the preset value, the telescopic cylinder 12 is controlled to retract to reset the moving plate 5, and the formed pipe fixing rod can be taken out. Depending on the pipe fixing rod with different bending angles or different lengths, the position of the concave wheel 9 is adjusted by the first bolt 8, and the positioning position is adjusted by the second bolt 11.
