Abstract
Description
Technical Field
[0001] This utility model relates to a molding tooling, specifically a hot wire high-temperature treatment molding tooling. Background Technology
[0002] In the X-ray tube, the hot filament plays a crucial role as a key component of the cathode. Typically spiral-shaped and made of tungsten wire, the hot filament heats up rapidly when an electric current passes through it, releasing free electrons. These electrons are then focused to form an electron beam, a process quite similar to the light-emitting principle of an incandescent lamp. Thus, the hot filament becomes the core element in generating X-rays, and its quality and manufacturing process directly determine the performance and lifespan of the X-ray tube.
[0003] Even after being left to stand for a period of time, hot-wire wound into a spiral shape will still exhibit springback deformation. The current process involves high-frequency heating immediately after winding to achieve rapid heating and shaping. However, this process has significant drawbacks. Due to the lack of specialized tooling, the consistency of the hot-wire is poor, resulting in a wide range of dimensional tolerances, making it difficult to meet the precise requirements of various customers.
[0004] Therefore, to improve the precision and consistency of the hot wire, a high-temperature setting process needs to be added after hot wire forming. This effectively ensures the dimensional accuracy of the hot wire after forming, significantly improving its consistency. In this high-temperature setting process, heat treatment forming fixtures are indispensable. Considering the extremely high operating temperature of the hot wire, the corresponding setting temperature must also be increased. This places stringent requirements on the fixture material. Conventional materials are easily deformed under high temperatures, resulting in a short service life and failing to achieve the desired effect of high-temperature hot wire forming. When selecting high-temperature resistant and non-deformable materials, the challenges of hardness and difficult mold processing are common. Even if high-temperature resistant fixtures are manufactured with great effort, their cost is quite high, and different specifications of fixtures are required, resulting in low versatility.

[0016] Furthermore, the first base plate is made of pure tungsten.

[0051] For different emitters, there are at least three requirements regarding the angle between the pins on both sides of the hot wire:
[0052] Requirement 1: The two pins on both sides of the hot wire are parallel and perpendicular to the wire body;
[0053] Requirement 2: The two pins on both sides of the hot wire need to have a certain angle requirement;
