Description

Technical Field

[0001] The utility model relates to the technical field of internal support mechanisms, in particular to an internal support mechanism used for thread rolling processing of external threads of nuts. Background Art

[0002] Externally threaded nuts, also known as swivel nuts, refer to nuts with threads on the outside of the nut. This type of nut is often used in situations where it is necessary to easily screw on or disassemble, such as lighting accessories, faucets, etc.

[0003] However, in the existing process of processing external threads on nuts, the nut is generally placed on the outer surface of a fixed rod, and then two sets of rollers are used to feed the nut for external thread processing. In this way, the inside of the nut cannot be supported and clamped, resulting in displacement of the nut when the roller is processing the nut, thereby affecting the processing quality of the nut. In view of the above problems, the inventor proposes an internal support mechanism for nut external thread rolling processing to solve the above problems. Utility Model Content
