Description

Swivel ring and its manufacturing method}

The present invention is a rotating ring and a method of manufacturing the same. To describe this in more detail, a rotating ring in which an outer ring is formed so as to be rotatable on the outside of an inner ring worn on a finger, the minimum area of the inner ring is locally expanded and molded to form an outer ring. It relates to a rotating ring that can rotatably restrain a ring and a method of manufacturing the same.

Typically, the outer ring is rotatably coupled to the inner ring to express a new design, give a religious meaning or a new aesthetic like a rosary ring, or have functionality including acupressure.

In this way, the rotating ring is manufactured by inserting a C-shaped outer ring with an inner diameter slightly larger than the outer circumferential diameter of the inner ring into the inner ring and shrink molding it, then welding the joint of the outer ring, and then polishing. At this time, the welding precision is Accordingly, the quality of the outer ring joint is determined, and a polishing process must be performed to refine the welded part, so the manufacturing process is diversifying.

Accordingly, in the previously disclosed No. 20-0199868, the inner ring is set to a size that allows the flange to fit into the outer ring, and the inner ring is temporarily inserted into the outer ring and expanded in a state where it is loaded on the taper of the inner ring expansion jig. A technology has been previously proposed to enlarge the inner ring and combine it with the outer ring by forcibly inserting the core into the jig and simultaneously spreading the wings given to the tapered part of the enlarging jig in the radial direction. However, due to enlarging the entire section of the inner ring, the outer shape is changed. Due to the deformation, the external design must be corrected through a separate finishing process, and due to the structural characteristics of the diameter expansion jig, which is placed at equal intervals, being spread by the core and pressurizing the inner peripheral surface of the inner ring, the inner peripheral surface of the inner ring that is interviewed by the diameter expansion jig is localized. A step is created by being compressed, and in particular, due to the inclination angle of the enlargement jig, the inner diameter of the inner ring is formed as an inclined hole structure that decreases from one end to the other end, so when the ring is worn, the inner diameter of the narrow side of the inner ring touches the skin. There was a problem that it was uncomfortable to wear due to localized contact.

In addition, in another prior art, Registered Utility Model No. 20-0464250, in manufacturing a double ring by combining two metals of different colors, a first outer ring is formed with an insertable first coupling jaw and a second coupling jaw. A technology comprising a third engaging jaw horizontally coupled to the outer ring and a second outer ring having a coupling groove, and an inner ring rotatably coupled between the first outer ring and the second outer ring. Although this line has been registered, the double ring is divided into three parts including the first and second outer rings and the inner ring, and after welding and joining the first and second outer rings, the welded area must be polished, so the work time is shortened. The delay resulted in a decrease in productivity.
