Description

Technical Field

[0001] The utility model relates to the technical field of copper welding, in particular to a one-time welding device for special-shaped thin-walled internally cooled copper parts. Background Art

[0002] In the technical field of copper welding, it often involves the situation of welding two copper parts with a large difference in thickness. For example, welding a special-shaped thin-walled copper tube and a copper plate. The wall thickness of the special-shaped thin-walled copper tube is only 1 mm, while the thickness of the copper plate is 6 mm. The welding condition of copper is flame heating. However, the welding area of the special-shaped thin-walled copper tube is large and the heat dissipation is fast, so it cannot be quickly welded to the thick copper plate in time. When the prior art welds these two parts, the welding often fails due to the large temperature difference. During welding, the special-shaped thin-walled copper tube is also prone to deformation due to excessive pressure. In addition, the high temperature during welding easily causes serious deformation of the copper plate, making it impossible to install semiconductor components. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that when the special-shaped thin-walled copper tube is welded after heating, the large welding area and fast heat dissipation cause the tube to quickly lose temperature and cannot be welded to the thick copper plate in time. During welding heating, high temperature and excessive pressure are likely to cause deformation of the tube and the copper plate, resulting in overall welding deformation. The utility model provides a one-time welding device for special-shaped thin-walled internally cooled copper parts.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] The utility model provides a one-time welding device for special-shaped thin-walled internally cooled copper parts. The one-time welding device includes: a welding fixing plate, and a cooling copper plate installed on the welding fixing plate;

[0006] An internal cooling tube is embedded in the cooling copper plate, and a welding pressing plate is installed on the internal cooling tube. The welding pressing plate is used to fix the cooling copper plate, and a side connection internal cooling plate is installed at one end of the cooling copper plate away from the welding pressing plate.

[0007] Preferably, the internal cooling tube includes an outer ring internal cooling tube and an inner ring internal cooling tube;

[0008] The inner ring internal cooling tube is arranged inside the outer ring internal cooling tube, and the outer ring internal cooling tube is embedded in the cooling copper plate.

[0009] Preferably, both ends of the side connection internal cooling plate are provided with closed plugs, and an auxiliary welding agent is coated on the closed plugs.

[0010] Preferably, the welding pressing plate is provided with a boss positioning, and the boss positioning is used to position and press the cooling copper plate.

[0012] The positive and progressive effects of the present utility model are as follows: The present utility model provides a disposable welding device for special-shaped thin-walled internally cooled copper parts. By embedding two special-shaped thin-walled copper tubes to be welded, namely the outer ring internally cooled tube and the inner ring internally cooled tube, on the cooling copper plate, the disposable welding device can ensure maintaining the temperature required for welding during the welding process, so as to ensure that the two special-shaped thin-walled copper tubes will not rapidly lose temperature during the welding process.

[0016] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0017] Embodiment

[0018] As Figure 1-2 shown, this embodiment provides a disposable welding device for special-shaped thin-walled internally cooled copper parts. The disposable welding device includes: a welding fixing plate 5, and a cooling copper plate 1 installed on the welding fixing plate 5; an internally cooled tube is embedded on the cooling copper plate 1, and a welding pressing plate 6 is installed on the internally cooled tube for fixing the cooling copper plate 1; wherein, the internally cooled tube includes an outer ring internally cooled tube 2 and an inner ring internally cooled tube 3; the inner ring internally cooled tube 3 is arranged inside the outer ring internally cooled tube 2, and the outer ring internally cooled tube 2 is embedded on the cooling copper plate 1. Specifically, both the outer ring internally cooled tube 2 and the inner ring internally cooled tube 3 are special-shaped thin-walled copper tubes, and the two are welded to the copper plate respectively through the disposable welding device of this embodiment.

[0019] In this embodiment, a side connection internal cooling plate 4 is installed at one end of the cooling copper plate 1. Both ends of the side connection internal cooling plate 4 are provided with closed plugs, and an auxiliary welding agent is coated on the closed plugs. Specifically, the side connection internal cooling plate 4 is a thick copper plate. Installing the side connection internal cooling plate 4 on the cooling copper plate 1 can maintain the temperature of the copper plate and avoid the serious deformation of the copper plate in a high-temperature environment. Here, the auxiliary welding agent is rosin. Using the auxiliary welding agent rosin can make the welding joint smoother and purer, reduce the welding temperature, shorten the welding time, and significantly improve the welding efficiency and quality.

[0020] In this embodiment, the welding pressing plate 6 is provided with a boss positioning, and the boss positioning is used to position and press the cooling copper plate 1. Specifically, the welding pressing plate 6 is installed at one end away from the side connection internal cooling plate 4, pressing the outer ring internal cooling tube 2 and the inner ring internal cooling tube 3 to prevent deviation and excessive pressure during welding, which may cause deformation of the pipe fittings and affect the welding success rate.

[0021] In this embodiment, the one-time welding device further includes a heating furnace 7, and the heating furnace 7 is used to heat the one-time welding device. Specifically, after assembly, the assembled welding device is placed in the heating furnace 7 and heated to 300 degrees Celsius and kept warm for 30 - 40 minutes to ensure the temperature required for the welding of the special-shaped thin-walled copper tubes, so that the temperature will not drop rapidly during subsequent manual welding, resulting in a large temperature difference from the copper plate and welding failure.

[0022] This embodiment provides a one-time welding device for a special-shaped thin-walled internal cooling copper part. By embedding two special-shaped thin-walled copper tubes to be welded, namely the outer ring internal cooling tube and the inner ring internal cooling tube, on the cooling copper plate, this one-time welding device can ensure that the temperature required for welding is maintained during the welding process, so that the two special-shaped thin-walled copper tubes will not lose temperature rapidly during welding. Placing the copper plate to be welded on the cooling copper plate and connecting it to the two special-shaped thin-walled copper tubes facilitates subsequent welding. Further, the welding pressing plate is used to fix the two special-shaped thin-walled copper tubes and the cooling copper plate to prevent excessive pressure during welding from causing deformation of the pipe fittings. This utility model completes the welding in two steps through this one-time welding device: overall heating and manual welding, achieving small overall welding deformation, high welding success rate, and fast welding speed.

[0023] The working principle of the present utility model is as follows: The cooling copper plate 1 is installed and fixed on the welding fixing plate 5. The outer ring internal cooling pipe 2 and the inner ring internal cooling pipe 3 are sequentially inlaid on the cooling copper plate 1, and then the welding pressing plate 6 is used to press the outer ring internal cooling pipe 2 and the inner ring internal cooling pipe 3. Then, the side connection internal cooling plate 4 is placed at one end of the cooling copper plate 1 away from the welding pressing plate 6, and the plugging heads at both ends of the side connection internal cooling plate 4 are coated with auxiliary welding agent. The assembled welding device is placed in the heating furnace 7 and heated to 300 degrees Celsius and kept warm for 30 - 40 minutes. Prepare the tin welding wire, and quickly weld after the welding device is taken out. The plugging heads at both ends of the side connection internal cooling plate 4, the outer ring internal cooling pipe 2, the inner ring internal cooling pipe 3 and the side connection internal cooling plate 4 are welded simultaneously.

The protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present utility model.
