Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-5 This utility model provides a bending device for steel pipe processing, including a support ring 6 and a placement platform 2. A first rotating ring 601 is rotatably connected to the center of one side of the support ring 6. Several evenly distributed second pads 607 are fixedly connected to the upper end of the first rotating ring 601. A second rotating ring 608 is fixedly connected to the upper end of the second pads 607. A protrusion 6010 is fixedly connected to the top of the first rotating ring 601. A second fixing block 609 is rotatably connected to the upper end of the protrusion 6010. A screw 603 is threadedly connected to the inner side of the second fixing block 609. A first fixing block 602 is fixedly connected to the other end of the screw 603. The inner side of the first fixing block 602 is fixedly connected to the support ring 6. Several evenly distributed first pads 606 are fixedly connected to the surface of the support ring 6 at a position outside the first rotating ring 601. A fixing rod 604 is fixedly connected to the surface of the first pads 606. The middle position of the fixing rod 604 is rotatably connected to the inner side of the first rotating ring 601 and the second rotating ring 608. The other end of 604 is rotatably connected to a clamping block 605. During operation, the steel pipe to be bent is first placed inside the support ring 6. The screw 603 is rotated. Since the screw 603 is threadedly connected to the second fixing block 609, and the second fixing block 609 is rotatably connected to the protrusion 6010, and the first fixing block 602 is fixed to the support ring 6, the rotation of the screw 603 will cause the second fixing block 609 to move, thereby pushing the protrusion 6010 to drive the first rotating ring 601 to rotate around the center of the support ring 6. When the first rotating ring 601 rotates, it will drive the second rotating ring 608 to rotate synchronously. During the rotation of the first rotating ring 601 and the second rotating ring 608, they will push the fixed rod 604, causing the fixed rod 604 to rotate around the connection point at the first pad 606. Finally, it will drive the clamping block 605 to move towards the steel pipe, thereby clamping and fixing the steel pipe. This structure can precisely adjust the position of the clamping block 605 through threaded transmission, ensuring stable clamping of steel pipes of different diameters, avoiding deviation of the steel pipe during bending, and improving bending accuracy.

[0018] Furthermore, such as Figure 1 and Figure 2 As shown, a protrusion 6010 is fixedly connected to the top end of the first rotating ring 601, and a second fixing block 609 is rotatably connected to the upper end of the protrusion 6010. A screw 603 is threadedly connected to the inner side of the second fixing block 609, and a first fixing block 602 is fixedly connected to the other end of the screw 603. The inner side of the first fixing block 602 is fixedly connected to the support ring 6. During operation, the screw 603 can drive the first rotating ring 601 to rotate, thereby enabling the clamping device to be tightened better and to be positioned better.

[0019] Furthermore, such as Figure 3As shown, a second fixed column 4 is symmetrically placed at the top center of the placement platform 2. During operation, before bending the steel pipe, the middle part or a specific position of the steel pipe can be placed on the second fixed column 4 according to the bending requirements of the steel pipe. The second fixed column 4 can provide auxiliary support for the steel pipe, prevent the steel pipe from sagging due to its own weight or external force, and ensure that the steel pipe is in a horizontal or preset stable state before bending, thus providing a guarantee for subsequent precise bending. Moreover, the symmetrical placement structure can make the support force balanced and avoid local deformation of the steel pipe.

[0020] Furthermore, such as Figure 1 and Figure 5 As shown, an arc-shaped fixing block 3 is fixedly connected to the upper end of the placement platform 2 at a position away from the support ring 6. A sliding groove 301 is provided on the inner side of the arc-shaped fixing block 3. A toothed plate 302 is fixedly connected to one side of the inner side of the sliding groove 301. A gear 303 that meshes with the toothed plate 302 is slidably connected to the inner side of the sliding groove 301. A first fixing post 304 is fixedly connected to the upper end of the gear 303. During operation, when it is necessary to bend the steel pipe, one end of the steel pipe is clamped and fixed by the clamping block 605 on the support ring 6, and the other end is placed on the first fixing post 304. The first fixed column 304 is mounted on the fixed column 304, and then the drive gear 303 rotates along the toothed plate 302 in the slide groove 301. The rotation of the gear 303 will drive the first fixed column 304 to move along the arc trajectory of the arc-shaped fixed block 3. During the movement of the first fixed column 304, an external force will be applied to the steel pipe, causing the steel pipe to bend along the preset arc trajectory. Through the meshing transmission between the gear 303 and the toothed plate 302, the moving speed and position of the first fixed column 304 can be precisely controlled, thereby achieving precise control of the bending angle of the steel pipe and meeting different bending requirements.

[0021] Furthermore, such as Figure 1 As shown, a device leg 1 is fixedly connected to the bottom corner of the placement platform 2. During operation, the device leg 1 supports the entire placement platform 2, keeping it at a suitable working height, which facilitates the operator to place, clamp, and bend the steel pipe. At the same time, the device leg 1 can isolate the device from the ground, preventing dust, water stains, etc. from corroding the bottom components of the device. The fixed connection at the bottom corner can ensure the overall stability of the device and prevent the device from tipping over during operation.

[0022] Working Principle: First, the entire device is supported in a suitable position by the device legs 1 at the bottom corner of the placement platform 2 to ensure stability. The steel pipe to be bent is placed on the placement platform 2, with one end placed inside the support ring 6 and the other end resting on the first fixed post 304. Simultaneously, the middle of the steel pipe is placed on the second fixed post 4, symmetrically positioned at the top center of the placement platform 2, as needed. The second fixed post 4 provides auxiliary support to the steel pipe, preventing it from sagging. Next, the screw 603 on the support ring 6 is rotated. The screw 603 engages with the second fixed block 609, causing the second fixed block 609 to move. This, in turn, pushes the protrusion 6010, causing the first rotating ring 601 to rotate around the center of the support ring 6. The first rotating ring 601 drives the second rotating ring 608 to rotate synchronously. Both together push the fixed rod 604 to rotate around the first pad 606, ultimately causing the clamping block 605 to clamp one end of the steel pipe. Then, the gear 303 in the sliding groove 301 of the drive arc-shaped fixing block 3 is engaged with the toothed plate 302, which drives the first fixing column 304 to move along the arc-shaped trajectory. The first fixing column 304 applies external force to the steel pipe, causing the steel pipe to bend along the preset trajectory. During this process, the stable support on the placement platform 2 ensures the stability of the clamping and bending process. Through the coordinated work of various components, the steel pipe is accurately and stably bent.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
