[0002] The pipe bending mechanism is the core component of a pipe bending machine. The clamping die secures the pipe to prevent axial movement, while a servo motor or mechanical transmission device transmits power to the bending mechanism, enabling precise speed and angle control. In the existing technology, CN213591480U describes a pipe bending mechanism for a pipe bending machine, including a worktable. A clamping block is located on one side of the upper end of the worktable, and a fixing block is located at the end of the worktable away from the clamping block. A threaded rod is inserted into a threaded hole in the middle of the fixing block, with a handle at one end of the threaded rod. A second clamping block, corresponding to the clamping block, is located at the top of the threaded rod, with a handle at one end of the threaded rod. A bending wheel is located at the upper end of a support block, with a threaded connection between the lower end of the bending wheel and a connecting rod in the support block. A positioning wheel is located in the middle of the upper end of the worktable, between the clamping block and the bending wheel. A pipe is placed on the worktable, connected to the clamping block, clamping block, positioning wheel, and bending wheel. Beneficial effects: It can bend pipes of different radii, increasing the application range of the pipe bending machine and improving its practicality.

[0003] Existing pipe bending machines have pipe bending mechanisms that are inconvenient for limiting the size of steel pipes when in use because the steel pipes are not the same size. Therefore, a new pipe bending mechanism for pipe bending machines is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem of inconvenient positioning caused by different steel pipe sizes, this utility model proposes a pipe bending mechanism for a pipe bending machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a pipe bending mechanism for a pipe bending machine, including a worktable, a limiting body fixedly connected to the top of the worktable, a DC motor mounted on the side of the limiting body, a double-threaded screw fixedly connected to the output end of the DC motor, the double-threaded screw rotatably connected to the inner wall of the limiting body, an inner slider threadedly connected to the outer wall of the double-threaded screw, a clamping clamp fixedly connected to the top of the inner slider, a first rotating roller rotatably connected to the inner wall of the clamping clamp, an auxiliary frame fixedly connected to the top of the limiting body, an electric push rod mounted on the inner wall of the auxiliary frame, an abutment plate fixedly connected to the output end of the electric push rod, and a second rotating roller rotatably connected to the bottom of the abutment plate.

[0006] Preferably, the bottom of the workbench is slidably connected to a mounting base, the top of the mounting base is fixedly connected to a track block, the inner surface of the track block is slidably connected to a locking block, and a pressing rod is fixedly connected between the locking blocks.

[0007] Preferably, an internal rod is fixedly connected to the side of the pressing rod, and an external rod is slidably connected to the outer wall of the internal rod.

[0008] Preferably, the external rod is fixedly connected to the inner surface of the mounting base, and the mounting base is fixedly connected to a spring via a pressing rod.

[0009] Preferably, the inner surface of the mounting base is provided with fixing holes, and fixing bolts are slidably connected to the inner surface of the mounting base.

[0012] Preferably, a limiting plate is fixedly connected to the top of the workbench, and the limiting plate is made of stainless steel.

[0013] The advantages of this utility model are: This invention uses a DC motor to drive a double-grooved screw to rotate, causing the clamping clamp and the first rotating roller to move and clamp each other, thereby limiting the two sides of the steel pipe. At the same time, the abutment plate descends to limit the top of the steel pipe, achieving the purpose of limiting steel pipes of different sizes and solving the problem of inconvenience in limiting different sizes of steel pipes.

[0014] This utility model, through the separate design of the mounting base and the worktable, allows the worktable to be limited by the use of locking blocks and springs, thus achieving the effect of assisting in fixing the worktable while facilitating its disassembly, solving the problem of inconvenient disassembly of the pipe bending mechanism after installation.

[0018] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a pipe bending mechanism for a pipe bending machine. (Refer to...) Figure 2 and Figure 3A pipe bending mechanism for a pipe bending machine includes a worktable 2. A limiting body 8 is fixedly connected to the top of the worktable 2. A DC motor 9 is mounted on the side of the limiting body 8. A double-threaded screw 10 is fixedly connected to the output end of the DC motor 9. The double-threaded screw 10 is rotatably connected to the inner wall of the limiting body 8. An inner slider 14 is threadedly connected to the outer wall of the double-threaded screw 10. A clamping clamp 15 is fixedly connected to the top of the inner slider 14. A first rotating roller 16 is rotatably connected to the inner wall of the clamping clamp 15. An auxiliary frame 12 is fixedly connected to the top of the limiting body 8. An electric push rod 18 is mounted on the inner wall of the auxiliary frame 12. An abutment plate 19 is fixedly connected to the output end of the electric push rod 18. A second rotating roller 17 is rotatably connected to the bottom of the abutment plate 19. The DC motor 9, in conjunction with the double-threaded screw 10, drives the double-threaded screw 10, which has a mirrored thread along its middle section, to rotate. This allows the inner slider 14 to slide relative to each other within the inner surface of the limiting body 8. Simultaneously, the clamping clamp 15 drives the first rotating roller 16 to abut against both sides of the steel pipe. During this process, the first rotating roller 16 can both clamp and limit the steel pipe without hindering its movement. After the electric push rod 18 is activated, the abutment plate 19 drives the second rotating roller 17 to descend as a whole, allowing the second rotating roller 17 to abut against the top of the steel pipe for limiting. The second rotating roller 17 can perform the same function as the first rotating roller 16.

[0020] Reference Figure 2 and Figure 4 The bottom of the worktable 2 is slidably connected to the mounting base 1, and the top of the mounting base 1 is fixedly connected to the track block 20. The inner surface of the track block 20 is slidably connected to the locking block 21, and the locking blocks 21 are fixedly connected to the pressing rod 22. By setting the locking blocks 21, the locking blocks 21 can be locked onto the top of the worktable 2, thereby playing the role of assisting in fixing the worktable 2 and limiting it inside the mounting base 1. Reference Figure 2 and Figure 4 An internal rod 24 is fixedly connected to the side of the pressing rod 22, and an external rod 23 is slidably connected to the outer wall of the internal rod 24. Through the internal rod 24 and the external rod 23, the pressing rod 22 can be pressed so that the movement of the locking block 21 can drive the internal rod 24 to slide inside the external rod 23. Reference Figure 2 and Figure 4 An external rod 23 is fixedly connected to the inner wall of the mounting base 1. The mounting base 1 is fixedly connected to a spring 25 via a pressing rod 22. The spring 25 is set so that after the pressing rod 22 is released, the locking block 21 can be springed back to the limiting worktable 2 by the spring 25, so that the bending mechanism can move the locking block 21 according to the user's needs. Reference Figure 1 and Figure 2 The inner surface of the mounting base 1 is provided with a fixing hole 11, and a fixing bolt 3 is slidably connected to the inner surface of the mounting base 1. By setting the fixing bolt 3, the pipe bending mechanism can be fixed to the pipe bending machine body by using the fixing bolt 3. Reference Figure 1 and Figure 2 The top of the workbench 2 is fixedly connected to a motor frame 5, and a servo motor 6 is installed on the top of the motor frame 5. Through the motor frame 5, the servo motor 6 can provide the kinetic energy for bending the pipe. Reference Figure 1 and Figure 2 The output end of the servo motor 6 is fixedly connected to the bending wheel 7. The outer wall of the bending wheel 7 is fixedly connected to the limit block 13. Through the setting of the bending wheel 7, the servo motor 6 can make the bending wheel 7 rotate freely after starting, so that the steel pipe can be limited inside the limit block 13 and then the bending wheel 7 can be used to bend the pipe. Reference Figure 1 and Figure 2 The top of the workbench 2 is fixedly connected to a limiting plate 4, which is made of stainless steel. The limiting plate 4 can assist the movement of the pipeline.

[0021] Working principle: A DC motor 9, in conjunction with a double-threaded screw 10, drives the screw 10, which has a mirrored thread along its central portion, to rotate. This causes the inner slider 14 to slide relative to each other within the inner wall of the limiting body 8. Simultaneously, the clamping clamp 15 drives the first rotating roller 16 to abut against both sides of the steel pipe. During this process, the first rotating roller 16 clamps and limits the steel pipe without obstructing its movement. Upon activation of the electric actuator 18, the abutment plate 19 lowers the second rotating roller 17, allowing it to abut against the top of the steel pipe for limiting. The second rotating roller 17 serves the same function as the first rotating roller 16. A locking block 21 engages with the top of the worktable 2, thus assisting in fixing the worktable 2 within the mounting base 1. The internal rod 24 and external rod 23 are configured so that after the pressing rod 22 is pressed, the movement of the locking block 21 can drive the internal rod 24 to slide inside the external rod 23. The spring 25 allows the locking block 21 to spring back to the limiting worktable 2 after the pressing rod 22 is released. This allows the bending mechanism to move the locking block 21 according to the user's needs. The fixing bolt 3 fixes the bending mechanism to the bending machine body. The motor frame 5 provides the bending kinetic energy for the bending. The bending wheel 7 allows the bending wheel 7 to rotate freely after the servo motor 6 is started. This allows the steel pipe to be bent by the bending wheel 7 after being limited inside the limiting block 13. The limiting plate 4 assists in the movement of the pipe.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
