Detailed Description
The utility model provides a glass sintering structure of metal tube, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the attached drawing and the embodiment is lifted the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the utility model provides a glass sintering structure of metal tube shell, refer to fig. 1 to fig. 2 together, it includes metal casing layer 1, metal transition layer 2 arranged in metal casing layer 1, glass lens layer 3 arranged in metal transition layer 2, and glass solder layer 4 arranged between metal transition layer 2 and glass lens layer 3; wherein, the expansion coefficients of the metal transition layer 2 and the glass solder layer 4 are the same or similar. A metal transition layer 2 is added between the metal shell layer 1 and the glass lens layer 3, and the expansion coefficients of the metal transition layer 2 and the glass solder layer 4 are the same or similar; when the glass lens is processed, the metal shell layer 1 and the metal transition layer 2 are welded, then the metal transition layer 2 and the glass lens layer 3 are connected through the glass welding material layer 4, and in the high-temperature sintering process, the glass lens layer 3 which is caused by the fact that the expansion coefficients of the metal shell layer 1 and the glass lens layer 3 have large difference can be effectively prevented from generating cracks to influence the product performance. In this embodiment, it is known to those skilled in the art that the expansion coefficients of the metal transition layer 2 and the glass solder layer 4 are similar, that is, those skilled in the art can determine that the glass material layer does not generate cracks within a certain difference range to affect the product performance according to the difference between the expansion coefficients of the two materials. Furthermore, the metal transition layer 2 and the glass solder layer 4 have the same coefficient of expansion. The implementation is that the glass solder is compactly connected with the metal transition layer 2 and the glass lens layer 3 through high-temperature sintering and solidification, so as to meet the sealing requirement of the connecting surface. And the connection has good stability.
Further, as shown in fig. 1 and fig. 2, a counter bore step 21 for accommodating the glass solder layer 4 is disposed on the metal transition layer 2. By adding the counter bore step 21 for accommodating the glass solder layer 4, the connection area of the glass solder layer 4 and the metal transition layer 2 can be increased, and the connection strength is improved.
The metal shell layer 1 comprises a main body layer 11 and a convex edge layer 12, and the counter bore step 21 and the convex edge layer 12 are respectively located at two ends of the metal transition layer 2. The counter bore step 21 and the convex edge layer 12 are respectively arranged at the two ends of the metal transition layer 2, so that the mutual influence between the sintering connection of the glass solder layer 4 and the metal transition layer 2 and the welding of the metal shell layer 1 and the metal transition layer 2 can be reduced, and the stability of the glass sintering structure of the metal tube shell is ensured.
Further, as shown in fig. 1 and 2, the thickness of the glass solder layer 4 is larger than the counterbore step 21. The thickness of the glass solder layer 4 is limited to be larger than the counter bore step 21, so that the groove at the position where the glass lens layer 3 is connected with the metal transition layer 2 due to the fact that the thickness of the glass solder layer 4 is too small can be prevented, and the connection strength of the glass lens layer 3 and the metal transition layer 2 is guaranteed.
Further, as shown in fig. 1 and 2, the glass solder layer is located inside the metal shell layer. Through setting up glass solder layer 4 in the inboard of metal casing layer 1, can effectual protection metal transition layer 2 and glass lens layer 3 junction not with external contact, improve the stability of the glass sintering structure of metal tube shell.
Further, as shown in fig. 1 and 2, the metal shell layer 1 and the metal transition layer 2 are connected by a brazing layer (not shown). The metal shell layer 1 and the metal transition layer 2 are connected through the copper-silver solder layer, so that the welding stability is high, and the production cost is low.
It should be understood that the application of the present invention is not limited to the above examples, and that modifications and changes can be made by those skilled in the art based on the above description, and all such modifications and changes are intended to fall within the scope of the appended claims.
