Description

Technical Field

[0001] This utility model relates to the field of vacuum sealing welding technology of titanium film and titanium alloy flange, specifically to a vacuum sealing welding structure of an ultra-thin titanium film and titanium alloy flange. Background Technology

[0002] Normally, welding of titanium metal and its alloys can be achieved using manual argon arc welding, a method capable of producing high-quality welds. However, when welding very thin titanium films—that is, titanium films no more than 0.2 mm thick—to titanium alloys, a more specialized vacuum brazing technique is typically employed.

[0003] When welding extremely thin titanium films to titanium alloys, the significant difference in thickness between the titanium film and the titanium alloy flange can lead to premature melting of the titanium film and burn-through of the weld when using traditional argon arc welding, resulting in an ineffective weld. Vacuum brazing effectively addresses this issue, producing high-quality welds. However, during vacuum brazing, the titanium film undergoes heating to up to 850 degrees Celsius, which significantly reduces its mechanical strength. Consequently, during the subsequent vacuum sealing process, the titanium film may be unable to withstand the external atmospheric pressure, ultimately leading to rupture. Currently, no solution has been proposed to address these technical problems. Utility Model Content

[0004] To address the problems in related technologies, this utility model proposes a vacuum sealing welding structure for an ultra-thin titanium membrane and a titanium alloy flange, overcoming the aforementioned technical issues in existing technologies. The purpose of this utility model is to solve the sealing problem of welding an ultra-thin titanium membrane to a titanium alloy without reducing the mechanical strength of the titanium membrane, while shortening the welding cycle and reducing welding costs. During the welding process, a titanium alloy pressure ring with a matching thickness is used for the titanium membrane, and continuous argon gas protection is provided inside the welding process. At the same time, by setting up connection mechanism one and connection mechanism two, the stability of the connection between the titanium membrane and the titanium alloy flange and the titanium alloy pressure ring is effectively improved, thereby further enhancing the weld's strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum-sealed welding structure for an ultra-thin titanium film and a titanium alloy flange, comprising a titanium alloy flange, a titanium film disposed on one side of the titanium alloy flange, and a titanium alloy pressure ring disposed on the side of the titanium film away from the titanium alloy flange. The titanium alloy flange and the titanium film are connected by a first connecting mechanism, and the titanium film and the titanium alloy pressure ring are connected by a second connecting mechanism. The first and second connecting mechanisms include a protrusion, a spring, and a locking block. One end of the protrusion is fixedly connected to the titanium film, and a locking groove is formed at the center of the top of the protrusion. The titanium alloy flange and the titanium alloy pressure ring are both provided with grooves that match the protrusion. The top of the groove is connected to a placement groove. One end of the spring is fixedly connected to the inner wall of the placement groove, and the other end of the spring is fixedly connected to the locking block.

[0006] Preferably, sealing rings are provided at both ends of the titanium membrane, and sealing grooves matching the sealing rings are provided on the opposite sides of the titanium alloy flange and the titanium alloy pressure ring.

[0007] Preferably, a sealing gasket is provided inside the sealing groove.

[0008] Preferably, the bottom end of the card block is inclined at an angle of 10° to 40°.

[0009] Preferably, the side of the bump away from the titanium film is inclined, with an inclination angle of 10° to 40°.

[0010] Preferably, both the first connecting mechanism and the second connecting mechanism are provided with several sets.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model is a vacuum sealing welding structure for an ultra-thin titanium film and a titanium alloy flange. By setting a first connection mechanism and a second connection mechanism, the stability of the connection between the titanium film and the titanium alloy flange or titanium alloy pressure ring can be improved. When it is necessary to connect the titanium film to the titanium alloy flange or titanium alloy pressure ring, the protrusion is inserted into the groove, and the locking block moves upward under the action of the spring. When the locking block and the locking groove on the protrusion are at the same horizontal line, the locking block is inserted into the locking groove, and the connection can be realized. This effectively improves the stability of the connection between the titanium film and the titanium alloy flange and the titanium alloy pressure ring, thereby further enhancing the strength of the welding.

[0013] (2) This utility model is a vacuum sealing welding structure of an ultra-thin titanium film and a titanium alloy flange. By setting a titanium alloy flange, a titanium film and a titanium alloy pressure ring, the sealing performance of the ultra-thin titanium film and the titanium alloy welding is solved without reducing the mechanical strength of the titanium film. At the same time, the welding cycle is shortened and the welding cost is reduced. The titanium film adopts a titanium alloy pressure ring with matching thickness during the welding process, and the internal argon gas is continuously protected during the welding process.

The connecting mechanism is divided into two parts: connecting mechanism one and connecting mechanism two, which include a protrusion 4, a spring 5, and a locking block 6. One end of the protrusion 4 is fixedly connected to the titanium film 2. A locking groove 7 is provided at the center of the top of the protrusion 4.

One end of the spring 5 is fixedly connected to the inner wall of the placement groove 8, and the other end of the spring 5 is fixedly connected to the locking block 6. Specifically, when it is necessary to connect the titanium film to the titanium alloy flange 1 or the titanium alloy pressure ring 3, the protrusion 4 is inserted into the groove, and the locking block 6 moves upward under the action of the spring 5. When the locking block 6 and the locking groove on the protrusion 4 are at the same horizontal line, the locking block 6 is inserted into the locking groove, and the connection is achieved.

[0020] Please see Figure 2 As shown, furthermore, sealing rings 9 are provided at both ends of the titanium membrane 2, and sealing grooves matching the sealing rings 9 are provided on the opposite sides of the titanium alloy flange 1 and the titanium alloy pressure ring 3.

[0021] In this embodiment, the sealing ring 9 is inserted into the sealing groove, which effectively improves the overall sealing performance.

[0030] This utility model, by setting up a first connection mechanism and a second connection mechanism, facilitates and improves the stability of the connection between the titanium diaphragm and the titanium alloy flange 1 or the titanium alloy pressure ring 3. When it is necessary to connect the titanium diaphragm to the titanium alloy flange 1 or the titanium alloy pressure ring 3, the protrusion 4 is inserted into the groove, and the locking block 6 moves upward under the action of the spring 5. When the locking block 6 and the locking groove on the protrusion 4 are at the same horizontal line, the locking block 6 is inserted into the locking groove, and the connection can be realized. This effectively improves the stability of the connection between the titanium diaphragm and the titanium alloy flange and the titanium alloy pressure ring respectively, thereby further enhancing the strength of the welding.

At the same time, the welding cycle is shortened and the welding cost is reduced. During the welding process, a titanium alloy pressure ring with matching thickness is used for the titanium membrane, and argon gas is continuously protected inside during the welding process.
