Stamping tool for electronic gun cathode bases

The utility model discloses a stamping tool for electronic gun cathode bases. The stamping tool comprises a base (1), a seat (2), a female die (3), a guide bushing (5) and a male die (6). The female die (3) and the seat (2) are arranged at the top of the base (1) sequentially from top to bottom. The guide bushing (5) encloses the seat (2) and the female die (3) so that the seat (2) and the female die (3) are fixed between the top of the base (1) and the guide bushing (5). The female die (3) and the guide bushing (5) are independently provided with a first through hole and a second through hole, respectively, which axially extend; the first through hole is used for mounting a cathode tube (9) of a cathode base (7). The male die (6) penetrates the first through hole and the second through hole so as to stamp metal powder (10) in the cathode tube (9). The steps of manufacturing the electronic gun cathode base are simple and environment friendly; the manufactured cathode base has excellent repeatability and stability.
