Working Mechanism of the RNF Series 7 Station Nut Former

1. Feeding System: The nut forming process begins with the feeding system, which automatically supplies the raw material, typically in the form of wire or bar, to the machine.


2. Cutoff Station: In the first station, the cutting mechanism cuts the wire or bar into the desired length for forming individual nuts.


3. Heading Station: The cut material is then transferred to the heading station, where it undergoes the initial shaping process. Here, the material is precisely positioned and formed into the basic shape of the nut head.


4. Thread Rolling Station: The partially formed nut then proceeds to the thread rolling station. In this station, the machine uses specialized dies to accurately roll threads onto the nut body, ensuring consistent thread quality and precise pitch.


5. Trimming Station: After thread rolling, the nut enters the trimming station. In this station, any excess material from the forming and thread rolling processes is trimmed off, creating a smooth and finished nut surface.


6. Chamfering Station: Following trimming, the nut moves to the chamfering station. Here, the machine uses cutting tools to create a beveled edge or chamfer on the ends of the nut, improving its functionality and ease of use.


7. Ejection System: Finally, the fully formed nut is ejected from the machine, ready for further processing or packaging.
