Description

Swivel ring and its manufacturing method {Swivel ring and its manufacturing method}

The present invention relates to a rotating ring and a method for manufacturing the same. To explain this in more detail, in a rotating ring in which an outer ring is formed to be rotatable on the outside of an inner ring fitted to a finger, the outer ring is formed by locally expanding a minimum area of the inner ring. It relates to a rotating ring capable of rotatably restraining the ring and a manufacturing method thereof.

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

In this way, the rotating ring is manufactured by shrink-molding a C-type outer ring whose inner diameter is slightly larger than the outer circumferential diameter of the inner ring by fitting it to the inner ring, then welding and polishing the joint of the outer ring. At this time, the welding accuracy is high. According to this, the quality of the outer ring joint is determined, and the manufacturing process is diversified because it must undergo a polishing process to trim the welded part.

Accordingly, in the conventionally disclosed No. 20-0199868, the inner ring has a dimension that allows the flange to enter the outer ring, and the inner ring is temporarily inserted into the outer ring while the inner ring is installed in the taper of the diameter expansion jig. A technique of forcibly inserting a core into a hardening jig and spreading the wings given to the taper part of the hardening jig at once in a radial direction to expand the inner ring and combine it with the outer ring has been suggested, but the outer shape is changed due to the expansion of the entire diameter of the inner ring It is deformed and the external design needs to be corrected through a separate finishing process, and the inner circumferential surface of the inner ring interviewed with the expansion jig is In particular, due to the inclination angle of the expansion jig, the inner ring inner diameter is formed in an inclined hole structure in which it is reduced from one end to the other end, so that when the ring is worn, the inner diameter of the inner ring is narrower than the skin. There was a problem that it was inconvenient to wear due to local contact with it.

In addition, in another prior art, Utility Model Registration No. 20-0464250, in manufacturing a double ring by combining two metals of different colors, a first outer ring having an insertable first coupling jaw and a second coupling jaw is formed. A second outer ring having a third coupling jaw and a coupling groove coupled horizontally with the outer ring is formed, and a technology consisting of an inner ring rotatably coupled between the first outer ring and the second outer ring Although this pre-registered bar, the double ring is diversified into three parts including the first and second outer rings and the inner ring, and after welding the first and second outer rings, the welding part must be polished, so the working time is reduced. The delay followed the negative consequences of lowering productivity.

The inner ring 20 is formed by lathe-processing a rod or tubular material, or is provided to be molded using a mold.

In addition, the first and second annular belt portions 21 and 22 are configured to restrain the outer ring 10 from both sides, and at this time, the second annular belt portion 22 is formed in a reduced size compared to the inner diameter of the outer hole 12 Accordingly, it is possible to insert into the outer hole 12.

3. Internal Step (S30)

In the inserting step (S30) according to the present invention, the outer ring 10 and the inner ring 20 are inserted by inserting the end of the inner ring 20 on which the second annular belt portion 22 is disposed into the outer hole 12 is the stage of assembling.

At this time, the outer ring 10 coupled to the inner ring 20 is temporarily assembled in a state in which one end is constrained to the first annular belt portion 21, and the second annular belt portion 22 in the tube expansion step (S40) to be described later It is molded (punched) so that the diameter is expanded, and the other end of the outer ring 10 is provided to be constrained.

4. Expansion step (S40)

In the tube expansion step (S40) according to the present invention, the conical punch 1 is inserted into the inner hole 23 where the second annular belt portion 22 is disposed, so that the outer diameter of the second annular belt portion 22 is the outer hole ( 12) This is a step of locally expanding an end portion of one side of the inner ring 20 so as to expand compared to the inner diameter.

The front end of the conical punch 1 is formed in a size smaller than the inner diameter of the inner hole 23, and the rear end of the conical punch 1 is formed in a size larger than the inner diameter of the inner hole 23.

Accordingly, when the conical punch 1 is press-fitted into the inner hole 23, the inner diameter of the inner hole 23 is expanded and the diameter of the second annular belt portion 22 is expanded compared to the inner diameter of the outer hole 12 to form an outer ring 10 it is imprisoned

At this time, the inner hole 23 is formed as a contraction inclined hole section 23a whose inner diameter is reduced from one end where the first annular belt portion 21 is formed to the other end, as shown in FIG. 2 (a).

And, as shown in FIG. 2(b), the contraction inclined hole section 23a is formed as an expansion inclined hole section 23b by expanding and molding one end region at an inclined angle by the conical punch 1 in the pipe expansion step (S40). do.

In this way, the inner hole 23 is provided so that the inner diameter expands from the center to both ends by the contraction inclined hole section 23a and the expansion inclined hole section 23b, that is, the inner diameter of the central area of the inner hole 23 is It is formed to be smaller than the inner diameter of both end regions, so it is not affected by the direction in which the user inserts the rotating ring, and it is easy to enter the finger and provides a stable and comfortable fit.

4 is a cross-sectional view showing an example in which a protective film is further configured in the method of manufacturing a rotary ring according to the present invention.

When the conical punch 1 is excessively pressed into the inner hole 23 in the tube expansion step (S40) during the manufacturing process of the rotating ring described above, the outer surface of the inner ring 20 and the inner diameter of the outer ring 10 come into contact with each other and rotate. Failure to do so will result in defects.

In order to prevent this, in the inner ring preparation step (S20), a protective film 30 is further formed on the outer surface of the inner ring 20 on the side of the second annular strip 22 to maintain a gap with the outer ring 10 After that, it goes through an inlet step (S30) and an expansion step (S40).

The protective film 30 is formed of a soft synthetic resin material to maintain the gap between the inner ring 20 and the outer ring 10 in the expansion step (S40), and at the same time, due to excessive expansion of the inner ring 20, the outer Damage to the ring 10 can be prevented.

The protective film 30 is removed in the process after the tube expansion step (S40), and the method of removing the protective film 30 is melted by high heat or chemicals, or broken into pieces using a laser, depending on the material of the film. It can be done in a variety of ways depending on the

As described above, the most preferred embodiment of the present invention has been described in the detailed description of the present invention, but various modifications may be made within a range that does not depart from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above embodiments, but the scope of protection should be recognized from the techniques of the claims to be described later and from these techniques to equivalent technical means.
