Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 As shown, the present invention is a stainless steel cold shrinkable tube flaring device, including a workbench 1, a mounting bracket 2 and an outer ring 3. A first rotating rod 8 is provided at the bottom of the workbench 1. Thread teeth 10 are provided on the surface of one end of the first rotating rod 8. A gear 9 is engaged with one side of the thread teeth 10. The upper surface of the gear 9 is connected with a second rotating rod 18. The second rotating rod 18 penetrates the workbench 1 and is connected with a first threaded rod 20. A second bearing 17 is installed on the outer side of the second rotating rod 18. The second bearing 17 is fixedly installed inside the workbench 1. First internally threaded sliders 14 and second internally threaded sliders 19 are engaged with the outer side of the first threaded rod 20. Connecting brackets 16 are movably connected to the surfaces of the first internally threaded sliders 14 and the second internally threaded sliders 19. A plurality of groups of connecting brackets 16 are provided. One end of the connecting bracket 16 is movably connected with a support rod 13. The upper end of the first threaded rod 20 is connected with a top plate 12. The connection between the first threaded rod 20 and the top plate 12 is set to be rotatable.

[0022] During use, the first rotating rod 8 is driven to rotate by the provided crank 7. The rotation of the first rotating rod 8 drives the rotation of the thread teeth 10, thereby driving the rotation of the engaged gear 9 on one side. The rotation of the gear 9 drives the rotation of the second rotating rod 18, and further drives the rotation of the connected first threaded rod 20. The rotation of the first threaded rod 20 enables the first internally threaded slider 14 and the second internally threaded slider 19 installed on its outer side to move towards each other. The movement of the first internally threaded slider 14 and the second internally threaded slider 19 drives the movement of one end of the connecting bracket 16, so that the other end pushes the support rod 13 outwards, thereby preliminarily fixing the pipe fitting. Through the provided adjustable outer support mechanism, it is convenient to fix pipe fittings of different sizes.

[0023] Please refer to Figure 1 The outer ring 3 is fixedly installed on the upper surface of the workbench 1. There are two groups of mounting plates 24 fixedly installed on the upper surface of the outer ring 3. There are clamping plates 25 arranged inside the mounting plates 24. One side of the clamping plate 25 is connected to a second threaded rod 23. The connection between the second threaded rod 23 and the clamping plate 25 is set to be rotatable. The other end of the second threaded rod 23 penetrates through the mounting plate 24 and is connected to a second crank 22. The second threaded rod 23 can rotate inside the mounting plate 24. By driving the second threaded rod 23 to rotate and move towards one end through the second crank 22, the clamping plate 25 is driven to move through the movement of the second threaded rod 23, so as to clamp the outside of the pipe fitting, thereby avoiding the situation of shaking when flaring the pipe fitting.

[0024] Please refer to Figure 3 The bottom of the top plate 12 is connected with sliding rods 15. There are two groups of sliding rods 15. The lower ends of the sliding rods 15 penetrate through the workbench 1 and extend to the lower end. The sliding rods 15 can slide inside the workbench 1. By providing the sliding rods 15, a limiting function can be achieved to prevent the support rod 13 from rotating during the adjustment process.

[0025] Please refer to Figure 2 There are multiple groups of mounting blocks 11 arranged on the outside of the first rotating rod 8. The upper ends of the mounting blocks 11 are fixedly installed at the bottom of the workbench 1. The other end of the first rotating rod 8 penetrates through a group of mounting blocks 11 and is connected to a first crank 7. The first rotating rod 8 can rotate inside the mounting block 11. By rotating the first crank 7, the first rotating rod 8 can be driven to rotate. By the rotation of the first rotating rod 8, the threaded teeth 10 can be driven to rotate. The provided mounting blocks 11 are used for installing and limiting the first rotating rod 8.

[0026] Please refer to Figure 1 Inside the upper end of the mounting frame 2, a hydraulic rod 5 is fixedly installed. The lower end of the hydraulic rod 5 is installed with a flaring die 6. The flaring die 6 can be detachably replaced. By providing the hydraulic rod 5 and the flaring die 6, the pipe fitting can be flared. By providing a detachable flaring die 6, dies of different sizes can be replaced for flaring.

[0027] Please refer to Figure 1 The bottom of the workbench 1 is installed with support feet 4. There are multiple groups of support feet 4. By providing the multiple groups of support feet 4, the function of supporting the device is achieved.

[0028] Working principle: The utility model is a stainless steel cold-shrinking pipe flaring device. First, the pipe to be flared is sleeved on the outside of the anti-slip pad 21, and then the crank 7 is rotated to drive the first rotating rod 8 to rotate. The rotation of the first rotating rod 8 drives the threaded teeth 10 to rotate, thereby driving the engaged gear 9 on one side to rotate. The rotation of the gear 9 drives the second rotating rod 18 to rotate, and further drives the connected first threaded rod 20 to rotate. Through the rotation of the first threaded rod 20, the first internal thread slider 14 and the second internal thread slider 19 installed on its outside can move towards each other. Through the movement of the first internal thread slider 14 and the second internal thread slider 19, one end of the connecting bracket 16 is driven to move, and the other end is pushed outward to push the support rod 13, thereby being able to fix the pipe fitting. Then, by rotating the second crank 22, the second threaded rod 23 is rotated and moved towards one end. The movement of the second threaded rod 23 drives the clamp plate 25 to move, thereby being able to clamp the outside of the pipe fitting. Finally, by starting the hydraulic rod 5, the flaring die 6 is driven to move downward to flare the pipe fitting. By setting the replaceable flaring die 6, pipe fittings of different sizes can be flared.
