[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-4 As shown, a metal pipe flaring device includes a base 1. Two supports 2 are fixedly installed on one side of the upper surface of the base 1. Annular support frames 3 are fixedly installed on the upper surface of each of the two supports 2. A rotating frame 5 is rotatably installed in the two annular support frames 3 through bearings 4. Several connecting sleeves 6 are fixedly installed on the inner wall of the rotating frame 5. Two positioning plates 7 are fixedly installed in each connecting sleeve 6. Sliding columns 8 are slidably arranged on opposite sides of adjacent positioning plates 7. A limit block 9 is fixedly installed at one end of each sliding column 8. A circular plate 10 is fixedly installed at the other end of each sliding column 8. A flaring mold 11 is provided on one side of each circular plate 10.

[0021] An external gear ring 12 is fitted on the surface of the rotating frame 5. A support seat 13 is fixedly installed on one side of the upper surface of the base 1. A motor 14 is fixedly installed on one side of the support seat 13. A crossbar 15 is rotatably installed on the other side of the support seat 13. A gear 16 is fitted on one side of the crossbar 15. The gear 16 meshes with the external gear ring 12.

[0022] The operator pushes the limit block 9, which moves the sliding column 8, causing the sliding column 8 to move the flaring mold 11. After the flaring mold 11 enters the opening of the metal pipe, it can squeeze the metal pipe. When the flaring mold 11 needs to be replaced, the operator controls the rotating frame 5 to rotate, so that the corresponding connecting sleeve 6 and the flaring mold 11 move to the position of the metal pipe opening, avoiding the need for operators to spend more time adjusting and replacing molds, and reducing manpower input.

[0023] In another embodiment of this utility model, a limiting ring 17 is sleeved on the body of the sliding column 8, and an elastic element 18 capable of compression and reset is sleeved on the side of the body of the sliding column 8 near the limiting ring 17.

[0024] The elastic element 18 is a spring.

[0025] By setting the elastic element 18, after the worker pushes the limiting block 9 to flare the metal tube with the flaring mold 11, the spring returns to its original position, allowing the spring to push the limiting ring 17.

[0026] In another embodiment of this utility model, each flaring mold 11 is fixedly installed on one side of the corresponding circular plate 10 by bolts 19.

[0027] By removing bolt 19, workers can disassemble the flaring mold 11, making it convenient for workers to quickly disassemble the worn flaring mold 11.

[0028] In another embodiment of the present invention, a positioning frame 20 is fixedly installed on the other side of the upper surface of the base 1, and a cylinder 21 is fixedly installed between the two sides of the inner wall of the positioning frame 20. The output end of the cylinder 21 passes through the positioning frame 20 and is fixedly installed with a push plate 22.

[0029] The staff started the cylinder 21, which caused its output end to drive the push plate 22 to move, so that the push plate 22 could push the limit block 9.

[0030] Working principle of a metal pipe flaring device:

[0031] In use, the operator pushes the limit block 9, which moves the sliding column 8, causing the sliding column 8 to move the flaring mold 11. After the flaring mold 11 enters the opening of the metal pipe, it can squeeze the metal pipe. When the flaring mold 11 needs to be replaced, the operator controls the rotating frame 5 to rotate, so that the corresponding connecting sleeve 6 and the flaring mold 11 move to the position of the metal pipe opening, avoiding the need for operators to spend more time adjusting and replacing the mold, and reducing manpower input.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
