Therefore, an internally threaded copper tube annealing device is proposed to address the above problems. Utility Model Content

The device platform 1 is fixedly connected to the tube winding mechanism 2 on the upper side, the device platform 1 is fixedly connected to the heating device 3 on the upper side, the device platform 1 is fixedly connected to the limiting mechanism 4 on the upper side, a bracket 41 is installed on the inner side of the limiting mechanism 4, a roller 42 is rotatably connected to the inner side of the bracket 41, one end of the roller 42 is fixedly connected to a limiting roller 43, a connecting plate 44 is fixedly connected to the upper end of the bracket 41, a motor 45 is fixedly connected to the other side of the connecting plate 44, a rotating shaft 451 is fixedly connected to the end of the main shaft of the motor 45, a first gear 452 is fixedly connected to the outer side of the rotating shaft 451, a fixing plate 5 is fixedly connected to the outer side of the bracket 41, a bearing 51 is fixedly connected to the inner side of the fixing plate 5, a rotating drum 52 is fixedly connected to the inner side of the bearing 51, a second gear 521 is fixedly connected to the outer side of the rotating drum 52, an elastic sheet 522 is fixedly connected to the outer side of the rotating drum 52, and a frosting sheet 523 is fixedly connected to the outer side of the elastic sheet 522.

[0026] As a further implementation of this solution, the first gear 452 is meshed and connected with the second gear 521, and the thickness of the first gear 452 is much greater than the thickness of the second gear 521. This facilitates the first gear 452 to drive the second gear 521 to rotate.

[0027] As a further implementation of the present invention, the end of the rotating drum 52 away from the elastic sheet 522 is in the same vertical plane as the fixed plate 5 , and the diameter of the rotating drum 52 is much larger than the diameter of the internally threaded copper tube, which can prevent the rotation of the rotating drum 52 from affecting the rotation of the limiting roller 43 .

[0028] As a further implementation of the present solution, the vertical cross-section of the elastic sheet 522 is arc-shaped, and the inner arc of the elastic sheet 522 faces the axis of the rotating drum 52, so that the elastic sheet (522) better conforms to the outer contour of the internally threaded copper tube.

[0029] As a further implementation of this scheme, the number of elastic sheets 522 is the same as the number of frosting sheets 523, and the elastic sheets 522 are evenly distributed at the same end of the rotating drum 52 with the axis of the rotating drum 52 as the center of the circle, so that the frosting sheets 523 can evenly grind the impurities attached to the surface of the internal threaded copper tube.

[0030] As a further implementation of this solution, the frosted sheet 523 is arranged on one side of the inner arc of the elastic sheet 522, and the inner and outer arc centers of the frosted sheet 523 are on the same axial line as the rotating drum 52, so that the inner arc contour of the frosted sheet 523 better fits the polished internal threaded copper tube.

[0031] As a further implementation scheme of the present scheme, the elastic sheet 522 is in a bundle shape from one end close to the rotating drum 52 to the direction away from the rotating drum 52, and the length of the elastic sheet 522 is much larger than the length of the frosted sheet 523, which can ensure that the frosted sheet 523 is always tightly attached to the surface of the polished internal threaded copper tube and avoid the frosted sheet 523 hindering the elastic change range of the elastic sheet 522.

[0032] Working process: During use, the equipment is powered on by an external power supply. When the internal threaded copper tube annealing device is used to anneal the internal threaded copper tube, the internal threaded copper tube is output after being heated by the heating device 3 on the device table 1, and then is wound on the rotating wheel on the winding mechanism 2 by the tube winding mechanism 2 through the inner side of the limiting mechanism 4. When the heated internal threaded copper tube is not completely cooled and passes through the limiting mechanism 4, the internal threaded copper tube penetrates the center position of the rotating drum 52 and a plurality of elastic sheets 522. When the internal threaded copper tube is pulled by the tube winding mechanism 2 and slides close to the limiting roller 43, the motor 45 fixedly connected to the upper end t of the bracket 41 through the connecting plate 44 can drive the rotating shaft 451 to rotate, and the rotating shaft 451 can drive the first gear 452 fixedly connected to the outside thereof to rotate, so that the first gear 452 fixed on the outside of the rotating drum 52 can exert a rotational force on the rotating drum 52. The rotating drum 52 is fixedly connected to the center position of the fixed plate 5 through the bearing 51, and the fixed plate 5 is fixed The rotating drum 52 is fixedly connected to the two brackets 41, and the rotating drum 52 can stably rotate on the inner side of the fixed plate 5 under the action of the second gear 521, and then the rotating drum 52 can drive the elastic sheet 522 fixedly connected at its end to rotate, and a plurality of evenly distributed elastic sheets 522 on the outer side of the rotating drum 52 wrap the internally threaded copper tube on the inner side of the rotating drum 52, and the frosted sheet 523 fixedly connected to the inner side of the elastic sheet 522 always clings to the surface of the internally threaded copper tube that runs through the rotating drum 52 under the elastic action of the elastic sheet 522, so that the elastic sheet 522 can be elastically connected to the inner side of the rotating drum 52. The frosting sheet 523 fixedly connected to the elastic sheet 522 rotates with the rotation of the rotating drum 52, and rotates and grinds the internally threaded copper tube sliding on the inner side of the rotating drum 52, so that impurities attached to the surface of the internally threaded copper tube that has not been completely cooled are polished away, and as the frosting sheet 523 wears, the elastic sheet 522 allows the frosting sheet 523 to always be in close contact with the internally threaded copper tube, ensuring that the frosting sheet 523 can always grind the internally threaded copper tube before it is completely worn out, and ensuring that the surface of the internally threaded copper tube after annealing is smooth.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
