Description

Technical Field

[0001] The utility model relates to the technical field of welding seam cooling, in particular to a ring welding seam cooling tool for inhibiting temperature conduction. Background Art

[0002] In the field of aviation and aerospace pipeline manufacturing, in aluminum alloy pipeline products with compensator structures, the compensator joints are connected by brazing of stainless steel and aluminum alloy. The high-temperature heat conduction during welding of the heterogeneous aluminum alloy weld about 30 mm away will affect the strength of the brazing point. Therefore, the temperature at 30 mm away from the weld must not be higher than 200°C during welding. The conventional cooling measure is to cool by winding copper foil or copper strip. This method often requires a larger contact surface, and the conducted heat accumulates on the copper foil or copper strip, and the heat is not effectively dissipated. This method has slow heat dissipation and slow cooling speed, and cannot meet the requirements of rapid cooling over short distances. Therefore, a device that can achieve rapid cooling within a range of 30 mm and suppress temperature conduction is needed. The utility model proposes a ring weld cooling tooling that suppresses temperature conduction. Utility Model Content

[0020] Example

[0021] like Figure 1-4 As shown, a ring weld cooling tooling for suppressing temperature conduction includes a cavity 1, a cooling cavity 5 is arranged in the cavity 1, a cover plate 2 is arranged at the top opening of the cooling cavity 5, and an air inlet 3 and an air outlet are respectively arranged at both ends of the cover plate 2, and the air inlet 3 and the air outlet are both connected to the cooling cavity 5.

[0022] It is worth mentioning that the cooling is carried out by fitting the part to be cooled through the cavity 1 provided, connecting with the external compressed gas tank through the air inlet 3 provided, introducing compressed air into the cooling cavity 5, and the compressed gas flows through the cooling cavity 5 provided, and the compressed gas enters through the air inlet 3 and is discharged from the exhaust pipe 4 and takes away the heat, and the cooling cavity 5 is sealed by the cover plate 2 provided.

[0023] In some feasible embodiments, the cavity 1 is semicircular. Specifically, two cavities 1 are combined to form a circular ring, which fits the outside of the pipe to be cooled. In particular, when in use, high-temperature tape is used to fix the two cavities 1. The high temperature generated during welding will cause the aluminum alloy pipe to expand due to the heat, so that the two cavities 1 are further clamped and fixed, and are not easy to fall off.

[0024] In some feasible embodiments, the air outlet is provided with an air outlet pipe 4. The air outlet pipe 4 can be extended according to actual conditions to prevent the airflow generated when the compressed air is discharged from the cooling chamber 5 from affecting the welding.

[0025] When in use, the two cavities 1 are clamped together at the position that needs to be cooled and temperature conduction is suppressed, and fixed with a special high-temperature tape. Compressed gas is introduced into the cooling cavity 5 through the compressed gas tank through the air inlet 3, and then welding is performed. During welding, compressed air is continuously introduced into the cooling cavity 5, and the compressed air continuously takes away heat for cooling. After welding is completed, the cavity 1 can be removed after the area around the weld is completely cooled.

[0026] In addition, it should be understood that although this specification is described in accordance with the implementation methods, not every implementation method contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
