Abstract

본 발명은 중심의 코아를 베이스표면 상하에 코아가 삽입될 수 있는 포켓을 형성하여 베이스와 코아를 상호 결합하여 완성되는 다금속 코인에 관한 것으로, 종래의 경우 링의 내경면에 홈이나 돌기를 형성하고 코아의 외경면에 이에 대응되는 돌기나 홈 아니면 평면형태로 제작하여 링의 내측에 코아를 삽입하고 프레스 가공에 의한 링과 코아의 결합 방식을 채택한 관계로 링의 경우 제작시 재료의 소모가 많았다.The present invention relates to a multi-metal coin that is completed by combining the core and the core by forming a pocket in which the core can be inserted above and below the base surface of the center core, and in the conventional case, a groove or a protrusion is formed on the inner diameter surface of the ring. In the case of the ring, the core was made into protrusions, grooves, or flat shapes corresponding to the outer diameter of the core, and the core was inserted into the ring. .

본 발명은 코아와 베이스를 상호 결합하되 판재를 타발하여 제작된 베이스 상하표면에 코아가 삽입될 수 있도록홈의 포켓을 형성시키어 스크랩이 없이 재료의 이용율을 높이면서, 포켓에지부를 코아에지부 두께보다 크게 하고 코아 외주면은 테이퍼와 돌기로 가공되어 프레스 가압시 포켓에지부의 변형이 선형되여 코아외주면 내의 빈틈을 충진 밀착 고정 결합이 용이하며 상하 코아 포켓 중앙면은 베이스와 일체형이므로 견고한 결합을 가능하게 하는데 그 목적이 있다.The present invention is to combine the core and the base, but the core can be inserted into the upper and lower surfaces of the base produced by punching the plate Forming a pocket of the groove to increase the utilization rate of the material without scrap, while the pocket edge portion is larger than the core edge portion thickness, the core outer peripheral surface is processed with taper and protrusion, so that the deformation of the pocket edge portion is linear during press press, so that the inside of the outer core surface Filling the gap is easy to close tight coupling and the top and bottom core pocket is integrated with the base, so the purpose is to enable a solid coupling.

Claims

In the manufacturing method of coins, which punches the core and presses the core on the upper and lower surfaces of the base through the process of punching the core and forming a taper, a protrusion, and an upper edge on the outer circumferential surface, the base and the core are tightly fixed. After making a core pocket on both sides or one side of the base and the core formed through the punching and outer peripheral surface forming process is inserted into the core pocket of the base and press-processed by the fixed metal and the core of the core Manufacturing method.

The method of claim 1, wherein the base core pocket edge portion has a height greater than the core edge portion and is bonded to each other.
