This template needs to be accurately positioned during processing, and the shell size at the riveting position must be smaller than the connecting nut size. The template needs to be made using a hand-operated press, which is labor-intensive, and the consistency of the connecting nut closing is poor, and the closing quality cannot be guaranteed. Therefore, it is necessary to make improvements to the above problems. Utility Model Content

After the connecting nut is closed, the closing size consistency is good, the operability is strong, the operation is simple and convenient, the labor intensity of the operator is reduced, the processing quality is improved, the production cycle is shortened, and the production efficiency is improved. The utility model is suitable for the closing and riveting of various connectors with similar structures such as SMC, BNC, Russian-made connectors and other closing structural components.

[0005] Among them, the outer end of the knife rod is formed with a mounting groove, and the closing wheel is located in the mounting groove. The outer end of the knife rod is fixed with a pin shaft rotatably connected to the closing wheel, and the spinning part of the outer edge of the closing wheel is located outside the mounting groove.

[0006] Furthermore, the closing wheel is an integrated structure consisting of a first equal diameter section, a tapered section and a second equal diameter section, wherein the tapered section is located between the first equal diameter section and the second equal diameter section, and the diameter of the first equal diameter section is greater than the diameter of the second equal diameter section.

[0007] Furthermore, the conical section is used to perform preliminary spinning on the closing position of the connecting nut, and the second equal-diameter section is used to perform final spinning on the closing position of the preliminary spun connecting nut.

[0010] 2. This technical solution adopts a one-piece closing wheel composed of a first equal-diameter section, a conical section and a second equal-diameter section.
