Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, specifically a bending device for steel pipe processing. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. According to the cross-sectional shape, they are divided into circular, square, rectangular and irregular steel pipes. Steel pipes are not only used to transport fluids and powdery solids, exchange heat energy, and manufacture mechanical parts and containers, but they are also an economical steel material. Most commonly bent steel pipes are circular steel pipes.

[0003] Currently, according to different bending processes, steel pipe bending can be divided into two methods: cold bending and hot bending. Cold bending can be further divided into several forms according to the way external force is applied: pressure bending, rolling bending, and tension bending. Pressure bending and rolling bending are difficult to control during bending, resulting in unstable bending quality. When bending pipes using ordinary methods, the outer wall of the pipe centerline is thinned by tensile force, while the inner wall is thickened by compressive force, which easily leads to cracking of the outer wall or wrinkling of the inner wall.

[0004] Therefore, this utility model provides a bending device for steel pipe processing. Utility Model Content

[0024] 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.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6 As shown in the figure, a bending device for steel pipe processing according to an embodiment of the present invention includes a workbench 1, a bending box 2 fixedly connected to the side wall of the workbench 1; a transmission gear 3 rotatably connected inside the bending box 2; a U-shaped bending block 4 fixedly connected to the end of the transmission gear 3; a bending clamping block 8 fixedly connected to the top of the U-shaped bending block 4; a first motor 5 fixedly connected to the side wall of the U-shaped bending block 4, and a first screw 6 fixedly connected to the output end of the first motor 5; a movable clamping block 7 threadedly connected to the end of the first screw 6 away from the first motor 5; a clamping head 9 fixedly connected to the side wall of the movable clamping block 7, and the clamping head 9 corresponds to the bending... The dimensions of the clamping block 8 are set as follows: A second motor 12 is fixedly connected inside the workbench 1, and a second screw 11 is fixedly connected to the output end of the second motor 12; the end of the second screw 11 away from the second motor 12 is threadedly connected to a drive rack 10; a support assembly is provided on the top of the workbench 1; during operation, the operator can bend the steel pipe by driving the second motor 12. In the process, the operator can first place the steel pipe to be bent on the top of the workbench 1 and use the support assembly to support the pipe. Then, the end of the pipe is placed in the position of the bending clamping block 8, and the first motor 10 is driven simultaneously. Machine 5 causes the first screw 6 to rotate. As the first screw 6 rotates, the movable clamping block 7, which is restricted by the U-shaped bending block 4 and threadedly connected to the first screw 6, will move horizontally. As the movable clamping block 7 moves closer to the bending clamping block 8, the clamping head 9 will contact the bending clamping block 8 to complete the fixing of the pipe fitting. At this time, the operator can drive the second motor 12 to rotate the second screw 11, thereby causing the active rack 10, which is threadedly connected to the second screw 11 and restricted by the internal space of the worktable 1, to move horizontally. At this time, the... The active rack 10 and the transmission gear 3 are meshed. The transmission gear 3 will rotate along with the movement of the active rack 10. As the transmission gear 3 rotates, the bending clamping block 8 and the clamping head 9 will rotate synchronously to achieve the bending of the pipe. The bending box 2 serves to fix the transmission gear 3 and its connected components. This step fixes the end of the pipe by setting the bending clamping block 8 and the clamping head 9. The bending of the pipe is completed by setting the active rack 10 and the transmission gear 3 in conjunction with the support components. This enhances the stability of the pipe bending equipment and helps to avoid displacement or detachment of the pipe during the bending process.

[0027] like Figures 1 to 5 As shown, the support assembly includes a fixed plate 15; a third motor 16 is fixedly connected to the side wall of the fixed plate 15, and a third screw 17 is fixedly connected to the output end of the third motor 16; a movable support block 18 is threadedly connected to the end of the third screw 17; a limit platform 23 is fixedly connected to the top of the workbench 1, and multiple limit platforms 23 are arranged correspondingly; a threaded tube 19 is provided inside the movable support block 18, and a support head 20 is fixedly connected to the side wall of the threaded tube 19; during operation, the operator can control the horizontal position of the support assembly by driving the third motor 16, thereby providing support force for the pipe and preventing the pipe from falling off during bending. During the process, whenever the third motor 16 is driven, that is, when the third screw 17 rotates, a support head 20 is threadedly connected to the third screw 17. The movable support block 18, which is connected to and restricted by multiple limiting platforms 23, will move. As the movable support block 18 moves, the threaded pipe 19 and the support head 20 set on the side wall of the movable support block 18 will move synchronously. Whenever bending is required, the operator can drive the third motor 16 so that the support head 20 contacts the side wall of the pipe fitting, providing support force for the pipe fitting. The fixing plate 15 serves to fix the third motor 16. This step, by setting up a support assembly composed of the third motor 16, the movable support block 18, the threaded pipe 19, and the support head 20, realizes the mobility of the support assembly, enhances the flexibility and practicality of the bending equipment for steel pipe processing, and helps to avoid the support assembly from hindering the movement of the pipe fitting.

[0028] like Figure 2 As shown, a fourth motor 22 is fixedly connected to the side wall of the movable support block 18, and a fourth screw 21 is fixedly connected to the output end of the fourth motor 22. The end of the fourth screw 21 is threadedly connected to the threaded pipe 19. During operation, after the operator causes the support head 20 to contact the side wall of the pipe, the support head 20 can be moved along with the pipe by driving the fourth motor 22. During the process, since the fourth screw 21 is threadedly connected to the threaded pipe 19, and the threaded pipe 19 and the support head 20 are restricted by the movable support block 18, the threaded pipe 19 and the support head 20 can move along with the rotation of the fourth screw 21. This step, by setting the fourth screw 21 and the fourth motor 22, realizes the mobility of the threaded pipe 19 and the support head 20, further enhancing the flexibility of the equipment, helping to avoid friction damage to the pipe caused by the components, and reducing safety hazards.

[0029] like Figure 6As shown, a limiting block 13 is fixedly connected inside the workbench 1; rollers 14 are rotatably connected inside the limiting block 13, and multiple rollers 14 are arranged in a linear array; a sliding groove is provided on the side wall of the active rack 10, and the sliding groove is set to correspond to the size of the rollers 14; during operation, whenever the active rack 10 moves, the multiple rollers 14 rotatably connected inside the limiting block 13 will contact the sliding grooves on the side wall of the active rack 10. With the movement of the active rack 10, the multiple rollers 14 can convert the sliding friction between the components into rolling friction. At the same time, the multiple rollers 14 can provide lateral support for the active rack 10. This step, by setting the limiting block 13, rollers 14 and the sliding grooves on the side wall of the active rack 10, reduces the friction between the components, enhances the stability of the active rack 10, helps to alleviate component wear, extends the service life of the equipment, and reduces the equipment maintenance requirements.

[0030] like Figures 1 to 3 As shown, a fixing protrusion 24 is fixedly connected to the side wall of the workbench 1, and multiple fixing protrusions 24 are arranged in a corresponding manner; a caster wheel 25 is fixedly connected to the bottom of the multiple fixing protrusions 24; during operation, the operator can move the equipment with the help of the multiple caster wheels 25, wherein the multiple fixing protrusions 24 fixed to the side wall of the workbench 1 serve to fix the caster wheels 25; this step provides convenience for the movement of the equipment by setting the fixing protrusions 24 and the caster wheels 25, enhances the flexibility of the equipment, and helps to solve the problem of inconvenience in moving large equipment.

[0031] like Figure 1 As shown, a guide block 26 is provided on the top of the workbench 1, and the guide block 26 is sized to correspond to the bending clamping block 8, the clamping head 9, and the support head 20. During operation, the operator can place the pipe on the top of the guide block 26 to bring the pipe to the appropriate position. This step simplifies the positioning and operation of the pipe by guiding the pipe with the guide block 26, which helps to solve the problem of pipe offset and enhances the convenience and stability of the equipment.

[0032] like Figures 1 to 6 As shown, the transmission gear 3, U-shaped bending block 4, bending clamping block 8, clamping head 9, support head 20, and active rack 10 are made of stainless steel. During operation, the stainless steel transmission gear 3, U-shaped bending block 4, bending clamping block 8, clamping head 9, support head 20, and active rack 10 can maintain a smooth surface for a long time, keeping the friction between components low and preventing rust from contaminating the pipe fittings. This step maintains the smooth surface of the transmission gear 3, U-shaped bending block 4, bending clamping block 8, clamping head 9, support head 20, and active rack 10 by using stainless steel, preventing iron filings from affecting the friction coefficient between components and contaminating the pipe fittings.

[0033] During operation, the worker can bend the steel pipe by driving the second motor 12. First, the worker places the steel pipe to be bent on top of the workbench 1 and supports it with a support assembly. Then, the end of the pipe is placed in the bending clamping block 8, and simultaneously the first motor 5 is driven, causing the first screw 6 to rotate. As the first screw 6 rotates, the movable clamping block 7, which is restricted by the U-shaped bending block 4 and threadedly connected to the first screw 6, moves horizontally. As the movable clamping block 7 moves closer to the bending clamping block 8, the clamping head 9 contacts the bending clamping block 8 to fix the pipe. At this point, the worker can drive the second motor 12 to rotate the second screw 11. This causes the drive rack 10, which is threadedly connected to the second screw 11 and constrained by the internal space of the worktable 1, to move horizontally. At this time, since the drive rack 10 meshes with the transmission gear 3, the transmission gear 3 will rotate along with the movement of the drive rack 10. As the transmission gear 3 rotates, the bending clamping block 8 and the clamping head 9 will rotate synchronously, achieving the bending of the pipe fitting. The bending box 2 serves to fix the transmission gear 3 and its connected components. The operator can control the horizontal position of the support components by driving the third motor 16, thereby providing support for the pipe fitting and preventing it from falling off during the bending process. During the process, whenever the third motor 16 is driven, i.e., when the third screw 17 rotates, the drive rack 10... The movable support block 18, which is threadedly connected to the 7th threaded section and restricted by multiple limiting platforms 23, will move. As the movable support block 18 moves, the threaded pipe 19 and support head 20, located on the side wall of the movable support block 18, will move synchronously. Whenever bending is required, the operator can drive the third motor 16 to make the support head 20 contact the side wall of the pipe, providing support for the pipe. The fixing plate 15 serves to fix the third motor 16. After the operator makes the support head 20 contact the side wall of the pipe, the fourth motor 22 can be driven to move the support head 20 along with the pipe. During this process, because the fourth screw 21 is threadedly connected to the threaded pipe 19, and the threaded pipe 19 and support head 20 are subject to… The movable support block 18 restricts the movement of the threaded pipe 19 and the support head 20, allowing them to move along with the rotation of the fourth screw 21. Whenever the drive rack 10 moves, multiple rollers 14, rotatably connected inside the limiting block 13, contact the grooves on the side wall of the drive rack 10. With the movement of the drive rack 10, the multiple rollers 14 convert the sliding friction between components into rolling friction. Simultaneously, the multiple rollers 14 provide lateral support for the drive rack 10. The operator can move the equipment using multiple casters 25. Multiple fixing protrusions 24, fixed to the side wall of the worktable 1, serve to fix the casters 25. The operator can place the pipe on top of the guide block 26, thus positioning the pipe appropriately.The transmission gear 3, U-shaped bending block 4, bending clamping block 8, clamping head 9, support head 20, and drive rack 10, all made of stainless steel, maintain a smooth surface over a long period, keeping the friction between components low and preventing rust contamination of the pipe fittings.
