Figure 1-5As shown, the pipe bending machine for the production of thermal pipe bending includes: a processing table 1, a mounting frame 2 is fixedly installed on the top of the processing table 1; a rotating shaft 3, the rotating shaft 3 is rotatably mounted on the mounting frame 2, a bending wheel 4 is fixedly mounted on the rotating shaft 3, for bending the thermal pipe to be bent, a limiting ring is fixedly installed on the bending wheel 4, for limiting the pipe head of the thermal pipe; an adjustable displacement bracket 5, the bracket 5 is set on one side of the bending wheel 4, and a guide wheel 6 is rotatably mounted on the bracket 5, for limiting the thermal pipe to be bent; a removable arc groove plate 20, the arc groove plate 20 It is arranged between the bending wheel 4 and the guide wheel 6, and is used to cushion the thermal pipe; a height-adjustable assembly frame 7, the assembly frame 7 is arranged above the mounting frame 2, and a mounting shaft 8 is rotatably mounted on the assembly frame 7, and a cutting disk 9 is fixedly mounted on the mounting shaft 8, for cutting off the bent thermal pipe; a first motor 10, the first motor 10 is fixedly mounted on the assembly frame 7, and the output shaft of the first motor 10 is fixedly connected to the mounting shaft 8 through a coupling; a driving mechanism for driving the rotating shaft 3 to rotate, and the driving mechanism is arranged on the processing table 1.

[0023] In this embodiment, the processing table 1 serves as the basic support platform of the entire pipe bending machine. The processing table 1 stably supports the subsequent working components and provides a stable operating environment for the entire bending process; the mounting frame 2 is fixedly installed on the top of the processing table 1, providing a stable installation position for the rotating shaft 3 and the bending wheel 4. The design of the mounting frame 2 ensures the stability and accuracy of the bending wheel 4 during the rotation process; the rotating shaft 3 is rotatably mounted through the mounting frame 2, and the bending wheel 4 is fixedly mounted on the rotating shaft 3. The bending wheel 4 is a key component that directly contacts the thermal pipe to be bent and completes the bending action through rotation; automated bending replaces manual operation, which not only improves production efficiency, but also reduces the inconsistency and accuracy problems of pipe bending caused by human factors; the bracket 5 is arranged on one side of the bending wheel 4, and the guide wheel 6 thereon cooperates with the arc groove plate 20 to limit and guide the thermal pipe. The arc groove on the arc groove plate 20 provides a clear bending path for the pipe, ensuring that the pipe can be deformed according to the predetermined curvature and direction during the bending process, which helps to improve the accuracy and consistency of the pipe bending. During the bending process, the pipe will be subjected to a large bending moment and stress. The grooved structure of the arc trough plate provides necessary support for the pipe, preventing excessive deformation or damage during the bending process. The adjustable displacement design of the bracket 5 allows it to accommodate thermal pipes of varying diameters, providing precise positioning, improving bend quality, and reducing scrap. The assembly frame 7 is located above the mounting frame 2 and is mounted with a rotatable mounting shaft 8. The cutting disc 9 is fixedly mounted on the mounting shaft 8. Adjusting the height of the assembly frame 7 ensures that the cutting disc 9 accurately cuts the bent thermal pipe. A first motor 10, serving as the power source, drives the mounting shaft 8 and cutting disc 9 through a coupling to achieve the cutting function. This integrated cutting function reduces production steps, lowering production costs and complexity. The height-adjustable design enhances the adaptability and flexibility of the equipment. As the power source for the cutting disc 9, the stable operation of the first motor 10 ensures accurate and efficient cutting. It is fixedly mounted on the assembly frame 7 for easy maintenance and replacement. A drive mechanism, mounted on the processing table 1, drives the rotating shaft 3 and bending wheel 4. Although the specific structure is not described in detail, its role is crucial and it is a key component for realizing automated bending; automated drive replaces manual or simple mechanical drive, improves production efficiency, and ensures the continuity and stability of the bending action.

[0024] In a further preferred embodiment of the present invention, the driving mechanism includes: a transmission shaft 11 rotatably mounted on the processing table 1; gears 12 fixedly mounted on the transmission shaft 11 and the rotating shaft 3, respectively, and the two gears 12 are meshed with each other; a mounting shell 13 fixed to the bottom of the processing table 1, and a second motor 14 is fixedly mounted in the mounting shell 13; pulleys 15 fixedly mounted on the output shaft of the second motor 14 and the transmission shaft 11, respectively, and the two pulleys 15 are provided with the same timing belt 16.

[0025] In this embodiment, the driving mechanism is designed in detail to drive the rotation of the rotating shaft 3 and the bending wheel 4 through a more precise and efficient transmission method, thereby realizing the automated bending of the thermal pipe; the transmission shaft 11 is rotatably mounted on the processing table 1, serving as an intermediate link in the power transmission. Its design needs to take into account sufficient strength and rigidity to withstand the torque and force during the transmission process. The two gears 12 are fixedly mounted on the transmission shaft 11 and the rotating shaft 3, respectively, and the two gears 12 are meshed. This gear transmission method has the characteristics of accurate transmission ratio and high transmission efficiency, and can ensure that the rotation speed of the rotating shaft 3 is consistent with that of the transmission shaft 11, thereby realizing precise control; the mounting shell 13 is fixed to the bottom of the processing table 1, providing a stable installation environment for the second motor 14. The second motor 14 serves as a driving source and provides power through the rotation of its output shaft; the pulley 15 and the timing belt 16 are fixedly mounted on the output shaft of the second motor 14 and the transmission shaft 11 respectively, and the two pulleys 15 are sleeved with the same timing belt 16; the timing belt 16 transmission realizes the smooth transmission of power from the second motor 14 to the transmission shaft 11, reduces vibration and noise, and improves the reliability and service life of the equipment.

[0026] In a further preferred embodiment of the present invention, a fixing frame 19 is fixedly installed on the top of the mounting frame 2, and an electric hydraulic rod 17 is fixedly installed on the top inner wall of the fixing frame 19. The output rod of the electric hydraulic rod 17 is fixedly connected to the assembly frame 7 for regulating the lifting and lowering of the assembly frame 7.

[0027] In this embodiment, the lifting and adjustment mechanism of the assembly frame 7 is optimized by introducing a combination of an electric hydraulic rod 17 and a fixed frame, achieving more precise and convenient lifting and lowering control. The fixed frame is fixedly mounted on the top of the mounting frame 2 and serves as a support platform for the electric hydraulic rod 17. The electric hydraulic rod 17 is fixedly mounted on the top inner wall of the fixed frame, and its output rod is fixedly connected to the assembly frame 7.

The cylinder 18 is a device that uses compressed air as a power source. By controlling the inlet and outlet of compressed air, the piston in the cylinder performs reciprocating linear motion, thereby driving the output rod to move laterally. When it is necessary to adjust the position of the bracket 5 on the mounting frame 2, the piston in the cylinder moves to one side by controlling the air intake or exhaust of the cylinder 18, thereby pushing the output rod and the bracket 5 to move laterally.

[0030] In a further preferred embodiment of the present invention, support legs are fixedly mounted on the bottom of the processing table 1 , and foot pads are fixedly mounted on the bottom ends of the support legs.

[0031] In this embodiment, the support legs are fixedly mounted on the bottom of the processing table 1. As the primary load-bearing components of the entire pipe bender, the number, layout, and material of the support legs must be appropriately designed based on the weight, operating environment, and stability requirements of the equipment. Foot pads are fixedly mounted on the bottom ends of the support legs and are typically made of wear-resistant and non-slip material. The primary function of the foot pads is to increase the contact area between the support legs and the ground, dissipating the pressure exerted by the equipment on the ground, and improving the stability and non-slip properties of the equipment.

[0032] In a further preferred embodiment of the present invention, a detachable access panel is provided on the mounting shell 13 , and the access panel is fixedly connected to the mounting shell 13 by screws.

[0033] In this embodiment, the structure of the mounting shell 13 is optimized, and a detachable inspection panel is added to greatly facilitate the maintenance and inspection of the equipment.

[0034] In a further preferred embodiment of the present invention, a shielding plate is provided on the mounting frame 2 , and bolts are provided on the shielding plate, and the bolts are threadedly connected to the mounting frame 2 .

[0035] In this embodiment, the shielding plate is a plate attached to the mounting frame 2, and its main function is to provide shielding protection to prevent people from accidentally touching and getting injured when components such as the gear 12 are in operation.

[0036] In summary, by replacing manual operation with automated bending, errors caused by human factors are reduced, and the consistency and accuracy of the bent pipes are improved. At the same time, the integrated cutting function further improves the overall production efficiency. The stable design of key components such as the mounting frame 2, the rotating shaft 3, and the bending wheel 4 ensures stability and accuracy during the bending process; the adjustable displacement design of the bracket 5 and the height-adjustable function of the assembly frame 7 enable the equipment to adapt to thermal pipes of different diameters and processing requirements, thereby improving the adaptability and flexibility of the equipment; the combination of gear 12 transmission and timing belt 16 transmission realizes efficient and smooth transmission of power from the second motor 14 to the rotating shaft 3.
