Description
Technical Field
The invention relates to the technical field of vacuum electronic devices. And more particularly to a welding die for an anode decoupling post.
Background
The long anode magnetron can generate high frequency power and has wide application in industrial heating and other aspects. The long anode structure in the long anode magnetron is not provided with a die separation belt, and the working frequency cannot be finely adjusted by adjusting the die separation belt like other magnetrons. Therefore, a long anode magnetron has extremely high requirements for the machining accuracy of the anode assembly.
In the conventional long anode magnetron anode assembly, the connection between the anode vane and the anode shell is processed in a split manner, as shown in fig. 1, and the anode vane is fixed with the anode shell by brazing. However, in the split processing mode, when the anode vane and the anode shell are brazed, a die is required to be used for positioning the anode vane so as to ensure the angle dividing precision of the anode vane. The problem that the brazing process exists is that the die is difficult to demold after being baked at high temperature, and because the anode blade made of the common oxygen-free copper material can be softened after being baked at high temperature, the anode blade is easy to deform in the demolding process, and the angle dividing precision cannot be guaranteed. Therefore, the machining mode using split machining cannot ensure machining accuracy.
The long anode magnetron anode assembly further comprises decoupling posts welded on the side end faces of the anode vanes, the decoupling posts functioning as: the coupling between the antenna and the cathode is reduced, the Q value (quality factor) of the resonant cavity is improved, the electron detonation of the cathode is reduced, and the sensitivity of the axial position of the cathode is reduced.
The reason that the connection of the anode vane and the anode shell in the existing long anode magnetron anode assembly adopts split processing is as follows: this way it is easy to weld the decoupling posts on the anode vane. The decoupling posts may be welded to the inside surface of the anode vane prior to brazing the anode vane to the anode casing, wherein the inside is relative to the welded integral anode vane to the anode casing. If the processing mode of the anode shell and the anode vane in the long anode magnetron anode assembly is adopted, although the processing precision between the anode vane and the anode shell can be improved, the decoupling column is not easy to process or the decoupling column is integrally processed, so that the cost of pipe manufacture is greatly increased. In particular, the inner side surface of the anode vane is arc-shaped, and the processing difficulty is increased.
Accordingly, there is a need to provide a welding die for anode decoupling posts that is easy to process and low cost, particularly suitable for long anode magnetrons having anode vanes integrally machined with the anode casing.

Wherein the inner side surface of the anode vane is arc-shaped.

Therefore, the decoupling column is accurately welded on the anode blade with low processing difficulty, low processing cost and high processing precision, and the high processing precision between the anode blade and the anode shell is realized.
The beneficial effects of the invention are as follows:

Further, the long anode magnetron can adopt an integrally processed anode assembly, and the processing precision between the anode vane and the anode shell is improved.

Detailed Description
In order to more clearly illustrate the present invention, the present invention will be further described with reference to preferred embodiments and the accompanying drawings. Like parts in the drawings are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and that this invention is not limited to the details given herein.
As shown in fig. 2 and 3 together, an embodiment of the present invention provides a welding mold for an anode decoupling column, which includes a base 20 and a cylindrical positioning mold 10 provided on the base 20, the diameter of the cylindrical positioning mold 10 being matched with the corresponding diameter of the inner side surface of each anode vane, wherein the inner side surface of the anode vane is arc-shaped. The top surface edge of the cylindrical positioning die 10 is provided with a plurality of positioning grooves 11 for accommodating solder and decoupling columns, each positioning groove 11 corresponds to the position of the decoupling column to be welded on the inner side surface of each anode vane, and each positioning groove 11 corresponds to the position of the decoupling column to be welded on the inner side surface of each anode vane. Since the positioning groove 11 is opened at the top surface edge of the cylindrical positioning die 10 and corresponds to the position of the decoupling column to be welded on the inner side surface of the anode vane, it can be determined that there is also a matching correspondence between the height of the cylindrical positioning die 10 and the height of the inner side surface of each anode vane.
Before the welding die provided by the embodiment is used for welding the decoupling column, the anode blade is brazed to the anode shell or the anode blade and the anode shell are integrally processed to form an anode assembly; then, a cylindrical positioning die 10 is placed into the anode assembly, so that a positioning groove 11 is aligned with the position of a decoupling column to be welded on the inner side surface of the anode blade; then, placing decoupling columns and solder in the positioning grooves 11, and starting welding; and finally, demolding, namely accurately positioning the welding position of the decoupling column after the integrated processing of the anode blade and the anode shell is completed, and welding the decoupling column on the anode blade. In summary, the welding mold provided in this embodiment can realize that the decoupling column is precisely welded on the anode blade with low processing difficulty, low processing cost and high processing precision, so that the integrated processing mode of the anode blade and the anode shell with high processing precision can be popularized and applied.
In particular, the cylindrical positioning die 10 is formed with an axially extending assembly hole 12 in the center, a through hole 13 extending radially along the cylindrical positioning die 10 is formed in the sidewall of the positioning groove 11, and the welding die further includes a positioning post 14 matching with the through hole 13. Wherein, the cylindrical positioning die 10 is centrally formed with an axially extending assembly hole 12, i.e. a hollow cylindrical positioning die 10 is formed. When the welding die with the structure is used for welding the decoupling column, after the decoupling column and the solder are placed in the positioning groove 11, the positioning column 14 is placed in the assembly hole 12, the decoupling column is fastened with the position of the decoupling column to be welded on the inner side surface of the anode blade through the matching of the positioning column 14 and the through hole 13, or the decoupling column is tightly contacted with the position of the decoupling column to be welded on the inner side surface of the anode blade through the matching of the positioning column 14 and the through hole 13, so that the processing precision is higher when welding is performed.
The assembly hole 12 is a through hole or a blind hole, and if the assembly hole is a blind hole, the bottom surface of the blind hole is lower than the bottom surface of the positioning groove 11. The assembly hole 12 is a through hole or a blind hole with the bottom surface lower than the bottom surface of the positioning groove 11, so that the positioning column 14 can be placed into the assembly hole 12 and the positioning column 14 is matched with the through hole 13.
In practice, each through hole 13 corresponds to a position of a decoupling column to be welded on the inside surface of each anode vane. In this way, the processing accuracy can be further improved.
In practice, the positioning column 14 is in threaded fit with the through hole 13, i.e. the through hole 13 is provided as a threaded hole, and the positioning column 14 is provided with threads matching the threaded hole. This structure enables screwing the positioning posts 14 into the through holes 13 to secure the decoupling posts in position with the decoupling posts to be welded on the inside surface of the anode vane. Further, the positioning column 14 is a hexagonal screw, which makes it easier to screw the positioning column 14 into the through hole 13 using a tool such as a wrench.
In specific implementation, the welding mold provided in this embodiment is used for a long anode magnetron in which the anode vane and the anode casing are integrally processed as shown in fig. 4. Wherein, the advantage of positive pole blade and the integrative processing of positive pole shell lies in: the anode vane is not required to be brazed, a die is not required to position the anode vane, the influence of demolding on the angle division precision of the anode vane is not required to be worried, and the coaxial precision between the inner diameter of the anode vane and the anode shell is high. The long anode magnetron with the anode vane and the anode shell integrally processed utilizes the welding die provided by the embodiment to weld the decoupling column on the anode vane, so that the advantages of the welding die provided by the embodiment can be exerted to the greatest extent, the decoupling column is accurately welded on the anode vane with low processing difficulty, low processing cost and high processing precision, and the high processing precision between the anode vane and the anode shell is realized.
