또한, 외측 금속재의 열간 가공시 외측 금속재가 인장할 수 있을 정도만 열간 가공이 이루어져 내/외측 금속재의 결합시 서로 들러붙지 않음으로써, 외측 금속재로 부터 내측 금속재가 회전 가능하도록 결합할 수 있는 유용한 발명이다.In addition, it is a useful invention that the inner metal material can be rotatably coupled from the outer metal material by performing the hot working only to the extent that the outer metal material can be tensioned during the hot working of the outer metal material, and thus do not stick together when the inner / outer metal material is joined. .

이하, 첨부된 도면을 이용하여 본 발명을 더욱 상세히 살펴보면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

본 발명은 내/ 외측 금속재(10, 20)를 결합하되, 내측 금속재(10)가 외측 금속재(20)의 공간부(S)에서 회전 가능하도록 결합하기 위한 제조방법에 관한 것이다.The present invention relates to a manufacturing method for coupling the inner / outer metal material (10, 20), the inner metal material 10 is rotatable in the space (S) of the outer metal material (20).

우선, 도 2에서 도시한 바와 같이, 일측으로 결합돌기(11)를 형성한 내측 금속재(10)를 제조하고, 상기 내측 금속재(10)가 결합할 수 있는 공간부(S)와 내측 금속재(10)의 결합돌기(11)와 대응하는 결합부(21)를 형성한 외측 금속재(20)를 제작한다.(금속재 제조단계)First, as shown in FIG. 2, the inner metal material 10 having the coupling protrusions 11 formed on one side thereof is manufactured, and the space S and the inner metal material 10 to which the inner metal material 10 can be coupled. The outer metal material 20 in which the engaging protrusion 11 and the coupling part 21 corresponding to the coupling protrusion 11 of FIG.

여기서, 상기 내측 금속재(10)의 결합돌기(11)는 양 측면으로 형성하되, 외측 금속재(20)의 결합부(21)보다 작은 크기로 형성하여, 내/ 외측 금속재(10, 20)가 결합이 완료된 상태에서 외측 금속재(20)의 공간부(S)에서 내측 금속재(10)가 회전할 수 있도록 형성하도록 한다.Herein, the coupling protrusion 11 of the inner metal material 10 is formed on both sides, but is formed to a size smaller than the coupling portion 21 of the outer metal material 20, the inner / outer metal material (10, 20) is coupled In this completed state, the inner metal material 10 may be formed to rotate in the space S of the outer metal material 20.

한편, 상기 외측 금속재(20)의 결합부(21)는 도 2에서와 같이 홀의 형태로 제작하여 내측 금속재(10)가 좌, 우측 방향으로 회전할 수 있도록 구성할 수 있으며, 도 3에서와 같이 외측 금속재(20)의 결합부(21a)를 원주방향으로 ㄷ자 홈 형태로 제작하여, 외측 금속재(20)의 원주 중심을 기준으로 회전할 수 있도록 형성할 수도 있다.On the other hand, the coupling portion 21 of the outer metal material 20 may be manufactured in the form of a hole as shown in Figure 2 so that the inner metal material 10 can be rotated in the left and right directions, as shown in FIG. The coupling portion 21a of the outer metal material 20 may be formed in a U-shaped groove in the circumferential direction, and may be formed to be rotated based on the circumferential center of the outer metal material 20.

그리고 상기와 같이 제작이 완료된 외측 금속재(20)를 열간 가공하여 인장이 이루어지도록 한다.(외측 금속재 인장단계)Then, as described above, the outer metal material 20, which has been manufactured as described above, may be hot worked to obtain tension.

이때, 상기 외측 금속재(20)의 열간 가공은 외측 금속재(20)가 인장이 발생할 수 있을 때까지 열을 가하는 것을 의미하며, 특히, 외측 금속재(10)의 재질에 따라 달라질 수 있는데, 예컨대, 녹는점이 높은 재질일수록 고온의 열로 가공할 수 있는 가공방법을 선택하고, 녹는점이 낮은 재질일수록 저온의 열로 가공할 수 있는 가공방법을 사용자가 선택함이 바람직하다.In this case, the hot working of the outer metal material 20 means that the outer metal material 20 is heated until tension can be generated, and in particular, may vary depending on the material of the outer metal material 10, for example, melting It is preferable that a material having a high point selects a processing method that can be processed with high temperature heat, and a material having a low melting point selects a processing method that can be processed with low temperature heat.

또한, 상기와 같이 외측 금속재(20)가 인장할 수 있는 열로 가공한 외측 금속재(20)의 공간부(S)에 내측 금속재(10)를 배치하도록 하며, 특히, 외측 금속재(20)의 결합부(21) 위치에 내측 금속재(10)의 결합돌기(11)가 결합할 수 있는 위치에 배치하도록 한다.(내측 금속재 배치단계)In addition, as described above, the inner metal material 10 is disposed in the space S of the outer metal material 20 processed by the heat to which the outer metal material 20 can be tensioned, and in particular, a coupling part of the outer metal material 20. At the position 21, the coupling protrusion 11 of the inner metal material 10 may be disposed at the position where the coupling protrusion 11 may be coupled.

그런 후, 열간 가공된 외측 금속재(20)를 냉각(외측 금속재 냉각단계)시켜 장식용 메달(50)을 완성하게 된다.Thereafter, the outer metal material 20 which has been hot worked is cooled (outer metal material cooling step) to complete the decorative medal 50.

여기서, 상기 외측 금속재 냉각단계에서 외측 금속재(20)의 냉각은 공랭식, 수냉식 등 다양한 방법으로 냉각할 수 있겠으나, 외측 금속재(20)의 크랙 등이 발생하지 않도록 공랭식으로 냉각하는 것이 바람직하다.Here, the cooling of the outer metal material 20 in the outer metal material cooling step may be cooled by various methods such as air cooling, water cooling, etc., but it is preferable to cool by air cooling so that cracks of the outer metal material 20 do not occur.

상기와 같이 본 발명은 외측 금속재(20)를 인장이 발생할 정도로만 열간 가공한 후, 외측 금속재(20)의 결합부(21)에 내측 금속재(10)의 결합돌기(11)를 결합시키기 때문에, 내측 금속재(10)의 결합돌기(11)와 내측 금속재(20)의 결합부(21)가 들러붙지 않은 상태에서, 냉각과정을 통해 인장되었던 외측 금속재(20)가 줄어들어 자연스럽게 결합이 이루어져, 외측 금속재(20)에 내측 금속재(10)가 회전 가능하도록 결합이 이루어지게 된다.As described above, according to the present invention, since the outer metal material 20 is hot-worked only to the extent that tension occurs, the coupling protrusion 11 of the inner metal material 10 is coupled to the engaging portion 21 of the outer metal material 20, so that the inner In a state where the coupling protrusion 11 of the metal material 10 and the coupling part 21 of the inner metal material 20 do not stick together, the outer metal material 20 which is tensioned through the cooling process is reduced, thereby naturally bonding, thereby forming the outer metal material ( 20 is coupled to the inner metal material 10 to be rotatable.

또한, 이러한 일련의 과정이 종래에 비해 제조과정이 간단하면서, 각각의 유니트를 제작함에 따른 공수 및 비용/ 인건비 등을 줄일 수 있어, 가격이 낮은 장식용 메달(50)를 공급할 수 있게 된다.In addition, such a series of processes are simpler than the conventional manufacturing process, it is possible to reduce the labor and cost / labor costs, etc. according to the production of each unit, it is possible to supply a low price decorative medal 50.

상술한 실시 예는 본 발명의 실시 예를 기재한 것으로, 본 발명은 이에 한정되지 않고, 본 발명의 기술적 사상이 벗어나지 않는 범위 내에서 다양한 형태로 실시 가능함을 명시한다.The above-described embodiment has described the embodiment of the present invention, and the present invention is not limited thereto, and the present invention can be implemented in various forms without departing from the technical spirit of the present invention.
