Description

Technical Field

[0001] The utility model belongs to the technical field of filament production, in particular to automatic forming equipment for an X-ray tube filament. Background Art

[0002] X-ray tubes are vacuum diodes operating at high voltage. They contain two electrodes: a filament for emitting electrons, which serves as the cathode, and a target for receiving electron bombardment, which serves as the anode. Both electrodes are sealed in a high vacuum glass or ceramic shell.

[0003] In the prior art, filaments are made in the following two ways. One is manual winding and forming. However, the head and tail ends of the manual winding need to be lengthened for production. Because the head end needs to be pressed and fixed, the cutting size of the tail end is difficult to control, so the two ends need to be lengthened, and a wire cutting and leading process needs to be added later. The pitch of the manually wound filament is difficult to control and needs to be wound with a mold core. In order to prevent the filament from rebounding after winding, it needs to be heated, and the production efficiency is low. Manual winding cannot solve the problem of center pinning, and a manual bending forming process needs to be added later. The second is winding and forming with special equipment, but the winding tooling mold is relatively complicated and needs to be wound and formed in a customized concave and convex mold core. The consistency requirements for raw materials are relatively high, and a set of molds corresponds to one specification. After the filament is formed, it needs to be shaped at high temperature with a customized mold to meet product requirements. Utility Model Content
