Description

Technical Field

[0001] This utility model relates to the field of brazing rings, specifically a deformation-resistant brazing ring. Background Technology

[0002] Brazing is a method of joining components by using a filler metal with a lower melting point than the base metal, heating the workpiece and filler metal to a temperature higher than the filler metal's melting point but lower than the base metal's melting temperature, and using the liquid filler metal to wet the base metal, fill the joint gap, and diffuse with the base metal. Brazing results in minimal deformation and smooth, aesthetically pleasing joints, making it suitable for welding precision, complex components and components composed of different materials. However, current brazing rings have a lower melting point than the base metal being welded, resulting in poor structural strength. This makes them prone to deformation during transportation due to compression, affecting the quality of the brazing process. Therefore, a deformation-resistant brazing ring is needed.

[0003] Existing brazed rings have poor resistance to deformation during use, and require flux to be applied to the welding area before brazing, resulting in low brazing efficiency. Therefore, there is an urgent need for a brazed ring with good resistance to deformation. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a brazed ring with anti-deformation properties to solve the problems of poor anti-deformation performance and poor efficiency of existing brazed rings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-deformation brazing ring, comprising a brazing filler ring, wherein a first coating is fixedly connected to the outer wall of the brazing filler ring, and a second coating is fixedly connected to the outer wall of the first coating.

[0006] The inside of the brazing ring is provided with a liquid storage tank, and a partition is fixedly connected to the inner wall of the brazing ring.

[0007] Preferably, the first coating is a polymer coating and the second coating is a PVD coating.

[0008] Preferably, the brazing ring and the first coating are in close contact, and the first coating and the second coating are in close contact.

[0009] Preferably, the first coating is sleeved on the outer wall of the brazing ring, and the second coating is sleeved on the outer wall of the first coating.

[0010] Preferably, the liquid storage tank is shaped like an arc, and the partition is embedded in one side of the inner wall of the liquid storage tank.

[0011] Preferably, the liquid storage tank contains M51-F flux, and the partition is made of lead-antimony alloy.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a brazing ring, a first coating, and a second coating. The first coating is fixedly connected to the outer wall of the brazing ring and is made of polymer, which can improve the deformation resistance of the brazing ring. The second coating is fixedly connected to the outer wall of the first coating and is made of PVD. The first coating and the second coating are tightly bonded together, which can improve the wear resistance of the brazing ring and prevent it from deforming under pressure.

[0014] 2. This utility model, through the setting of a brazing ring, a liquid storage tank, and a partition, has a liquid storage tank inside the brazing ring containing M51-F flux. When the brazing ring is heated, the partition, made of lead-antimony alloy, melts first, allowing the M51-F flux to flow out and cover the welding area. This eliminates the step of applying flux to the welding area before brazing, thereby improving the efficiency of brazing. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4A deformation-resistant brazing ring includes a brazing filler ring 1. A first coating 2 is fixedly connected to the outer wall of the brazing filler ring 1, and a second coating 3 is fixedly connected to the outer wall of the first coating 2. The first coating 2 is made of polymer coating, and the second coating 3 is made of PVD coating. The brazing filler ring 1 and the first coating 2 are tightly fitted together, and the first coating 2 and the second coating 3 are tightly fitted together. The first coating 2 is sleeved on the outer wall of the brazing filler ring 1, and the second coating 3 is sleeved on the outer wall of the first coating 2, which can improve the deformation resistance of the brazing ring.

[0023] Please see Figure 1-4 A type of anti-deformation brazing ring, wherein a liquid storage tank 4 is provided inside the brazing ring 1, and a partition 5 is fixedly connected to the inner wall of the brazing ring 1. The liquid storage tank 4 is arc-shaped, and the partition 5 is embedded in one side of the inner wall of the liquid storage tank 4. M51-F flux is placed inside the liquid storage tank 4, and the partition 5 is made of lead-antimony alloy, which can improve the efficiency of brazing.

[0024] Working principle: During use, a first coating 2 is fixedly connected to the outer wall of the brazing ring 1. The first coating 2 is made of polymer coating, which can improve the deformation resistance of the brazing ring. A second coating 3 is fixedly connected to the outer wall of the first coating 2. The second coating 3 is made of PVD coating. The first coating 2 and the second coating 3 are tightly bonded together, which can improve the wear resistance of the brazing ring and prevent it from deforming under pressure. A liquid storage tank 4 is opened inside the brazing ring 1, and M51-F flux is placed inside the liquid storage tank 4. When the brazing ring 1 is heated, since the partition 5 is made of lead-antimony alloy, the partition 5 can melt first, causing the M51-F flux to flow out and cover the welding area. This eliminates the step of applying flux to the welding area before brazing, thereby improving the efficiency of brazing to a certain extent. This completes the use of the device.
