As Figure 5 shown, this hanger greatly reduces its contact with the cylindrical product 50, ensures the dipping treatment effect of the cylindrical product 50, and reduces scratches on the cylindrical product 50 caused by the hanger.

[0036] Furthermore, the material used for the cylindrical product 50 is 46 brass.

[0037] As Figure 2 shown, the support frame 10 is an integrally formed structure, and the two legs 15 of the support frame 10 are bent successively from top to bottom to form a first straight part 11, a bending part 12, and a second straight part 13.

[0038] As Figure 2 shown, the bottom end of the second straight part 11 is bent to form a hook 14, and this hook 14 is used to hang the cylindrical product 50.

[0039] Furthermore, the radius of the positioning semi-ring 20 is 50 mm.

[0040] As Figure 1 shown, the positioning semi-ring 20 is welded and fixed to the bending part 12 of the support frame 10.

[0041] As Figure 1 and Figure 3 shown, the first support semi-ring 21 of the positioning semi-ring 20 includes a first connecting part 23 and a support part 22, the other end of the positioning semi-ring 20 is bent to form a second connecting part 24, and the first connecting part 23 of one positioning semi-ring 20 and the second connecting part 24 of the other positioning semi-ring 20 are welded and connected to enhance the connection stability of the two positioning semi-rings 20 on the support frame 10.

[0042] Furthermore, both the first connecting part 23 and the second connecting part 24 of the positioning semi-ring 20 are linear, and the lengths of both the first connecting part 23 and the second connecting part 24 are 3.75 mm.

[0043] Furthermore, the support part 22 is U-shaped.

[0044] Furthermore, the support frame 10, the positioning semi-ring 20, and the connecting rod 30 are all bent from stainless steel wires with a radius of 3 mm.

[0047] The working principle of this application is:

[0048] (1) Assembly of the hanger for dip painting of tubular products:

[0049] S1. As Figure 1 shown, the two positioning half-rings 20 are respectively welded to the bent portion 12 of the support frame 10, and the two positioning half-rings 20 are centrosymmetric, and the center of symmetry is the center of the positioning half-ring 20;

[0050] S2. As Figure 1 and Figure 3 shown, the first connecting portion 23 of one positioning half-ring 20 is welded to the second connecting portion 24 of the other positioning half-ring 20 to improve the stable connection of the two positioning half-rings 20;

[0051] S3. As Figure 1 shown, the connecting rod 30 is welded to the two positioning half-rings 20 to enhance the overall structural stability of the hanger.

[0052] So far, the assembly of the hanger for dip painting of tubular products is completed.

[0053] (2) Usage steps of the hanger for dip painting of tubular products:

[0054] S1. In the initial state, the tubular product 50 is horizontally placed on the workbench;

[0055] S2. The hanger is slowly inserted from the bottom of the tubular product 50 until the hook 14 of the support frame 10 contacts the bottom edge of the tubular product 50, and at the same time, the top of the support frame 10 passes through the tubular product 50;

[0056] S3. Slowly lift the top of the support frame 10 to make the hanger become vertical, and at the same time, the tubular product 50 follows the hanger to become vertical;

[0057] S4. Slowly lift the hanging rack and place it together with the cylindrical product 50 into the dipping tank until the dipping process of the cylindrical product 50 is completed; during the dipping process of the cylindrical product 50, due to the buoyancy of the paint liquid, the cylindrical product 50 shakes, and the inner wall of the cylindrical product 50 inevitably comes into contact with the flexible sleeve 40. Because of the flexible contact, it will not cause damage to the inner surface of the cylindrical product 50;

[0058] S5. As Figure 5 shown, after the dipping is completed, lift the cylindrical product 50 out of the dipping tank, and manually touch up the paint on the contact part at the bottom of the cylindrical product 50 of the hanging hook 14.

[0059] In the use step S3 of the hanging rack for dipping cylindrical products, the first support half-ring 21 of the positioning half-ring 20 and the second support half-ring 31 of the connecting rod 30 prop up and drive the cylindrical product 50 to become vertical; since the flexible sleeve 40 is sleeved on both the first support half-ring 21 and the second support half-ring 31, the flexible sleeve 40 will not scratch the inner surface of the cylindrical product 50 when coming into contact with the inner wall of the cylindrical product 50 during the process of changing from horizontal to vertical, ensuring the processing quality of the cylindrical product 50.

[0060] In the use step S4 of the hanging rack for dipping cylindrical products, the height of the cylindrical product 50 immersed in the dipping tank can be adjusted according to actual needs, improving the flexibility of the dipping process.
