Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a seamless pipe bending production equipment, including a driving mechanism 1, a supporting mechanism 2 and a bending mechanism 3, the driving mechanism 1 is located at one side of the supporting mechanism 2, the bending mechanism 3 is located at the periphery of the supporting mechanism 2, the driving mechanism 1 includes a first driving frame 11 and a second driving frame 12, the supporting mechanism 2 includes a supporting platform 21, the supporting platform 21 is provided with a first guide wheel 22 and a second guide wheel 23, the bending mechanism 3 includes a fixed platform 31 and a rotating platform 32, the rotating platform 32 is provided with a bending wheel 33, the rotating platform 32 can rotate relative to the fixed platform 31, when the rotating platform 32 rotates, it drives the bending wheel 33 on its upper part to rotate synchronously, and the pipe body 4 is bent by the bending wheel 33.

[0026] Among them, the driving mechanism 1 is used to drive the tube body 4, the supporting mechanism 2 is used for limiting and guiding to prevent the tube body 4 from leaving the platform during bending and to locate the bending position, and the bending mechanism 3 is used to bend the tube body 4 and process it into a bent tube structure to realize the production of seamless bent tubes.

[0027] A guide channel is formed between the first guide wheel 22 and the second guide wheel 23 , a feeding channel is formed between the first drive frame 11 and the second drive frame 12 , and the tube body 4 is placed in the feeding channel and the guide channel.

[0028] Among them, the spacing between the first guide wheel 22 and the second guide wheel 23 is adapted to the diameter of the tube body 4, the spacing between the first drive frame 11 and the second drive frame 12 is adapted to the diameter of the tube body 4, and the multiple groups of rollers 112 of the first drive frame 11 and the second drive frame 12 rotate in opposite directions. The rollers 112 convert the rotational force into a linear driving force, and rely on the linear driving force to drive the tube body 4 to move linearly. The bending position is adjusted by controlling the extended length of the tube body 4 relative to the first guide wheel 22 and the second guide wheel 23.

[0029] A first gear 34 is disposed at the lower end of the rotating platform 32 .

[0030] The fixing platform 31 has a second motor 35 built therein, and an output shaft of the second motor 35 is fixedly connected to a second gear 36 via a coupling, and the second gear 36 is meshed with the first gear 34 for transmission.

[0031] Among them, the rotating table 32 is connected to the fixed table 31 through a bearing, and the rotating table 32 can rotate relative to the fixed table 31.

[0032] Among them, when the second motor 35 works, it drives the second gear 36 to rotate. The second gear 36 drives the first gear 34 to rotate through meshing transmission. The first gear 34 drives the rotating table 32 to rotate relative to the fixed table 31, and the rotating table 32 drives the bending wheel 33 on its upper part to rotate;

[0033] As Figure 6 shown, when the bending wheel 33 rotates, it contacts the pipe body 4 and bends the pipe body 4 to form a bent pipe structure. The bending degree of the pipe body 4 is controlled by the rotation angle of the rotating table 32, which is convenient for adjusting the bending degree of the seamless bent pipe and is suitable for processing and forming straight pipes.

[0034] Among them, both the first driving frame 11 and the second driving frame 12 include a base plate 111. Multiple groups of roller bodies 112 are arranged at the upper end of the base plate 111, and a synchronous pulley base 113 and a first motor 114 are arranged at the lower end of the base plate 111.

[0035] Among them, multiple groups of synchronous pulleys and synchronous belts are built in the synchronous pulley base 113.

[0036] Among them, the synchronous pulleys are installed at the lower ends of the roller bodies 112, and the synchronous belts are arranged between two groups of synchronous pulleys.

[0037] Among them, the output shaft of the first motor 114 is fixed to one group of synchronous pulleys through a coupling.

[0038] Among them, when the first motor 114 works, it drives the synchronous pulley at one end of it. Through the transmission of the synchronous pulley synchronous belt assembly, multiple groups of roller bodies 112 rotate synchronously. The rotation directions of the multiple groups of roller bodies 112 of the first driving frame 11 and the multiple groups of roller bodies 112 of the second driving frame 12 are opposite. When the pipe body 4 is placed between the multiple groups of roller bodies 112 of the first driving frame 11 and the multiple groups of roller bodies 112 of the second driving frame 12, the pipe body 4 can move linearly under the drive of the roller bodies 112.

[0039] Working principle: A pipe body 4 is placed in the feeding channel and the guiding channel. The first motor 114 of the first driving frame 11 and the second driving frame 12 operates to drive the multiple groups of roller bodies 112 of the first driving frame 11 and the multiple groups of roller bodies 112 of the second driving frame 12 to rotate in opposite directions. The roller bodies 112 convert the rotational force into a linear driving force, and rely on this linear driving force to drive the pipe body 4 to move linearly. By controlling the extending length of the pipe body 4 relative to the first guiding wheel 22 and the second guiding wheel 23, the bending position is adjusted. After the bending position is determined, the second motor 35 operates to drive the second gear 36 to rotate. The second gear 36 drives the first gear 34 to rotate through meshing transmission. The first gear 34 drives the rotating table 32 to rotate relative to the fixed table 31. The rotating table 32 drives the bending wheel 33 on its upper part to rotate. When the bending wheel 33 rotates, it contacts the pipe body 4 and bends the pipe body 4 to form a bent pipe structure. The bending degree of the pipe body 4 is controlled by the rotation angle of the rotating table 32. After the bending is completed, the rotating table 32 drives the bending wheel 33 to reset under the drive of the second motor 35, and then the bent pipe is pulled out for discharging.
