Claims (1)

프레스에 의해 만들어진 원형링(1)이 금형속으로 자동 이송되게 한 공지의 전용단조기로서 슬라이드(4)가 하강하면서 중심펀치(7)이 고정된 펀치 고정판(5)이 스프링(6)을 눌르면서 중심펀치(7)이 원형링(1)의 내부로 삽입되면서 제품의 중심을 맞추고 펀치고정판(5)가 더욱 아래로 내려가면서 중간판(8)을 누르게되고 중간판(8)은 다시 상형(9)을 누르게 되면 상형(9)가 스프링(15)을 눌르면 원형링(1)의 외주면(2)을 압착하게 하여 후렌치(2′)가 형성되게 하고 이때 중심펀치(7)의 경사 압착부(10)이 원형링의 내측에 경사부(11)을 형성하고 중간판(8)와 상형(9)의 내부에서 스프링(6)에 탄발케 된 부시(14)는 스프링의 압착으로 원형링에는 아무런 영향을 주지 않고 내측으 밑부분은 스프링(13)에 지지된 정지핀(12)에 의하여 근소한 라운딩이 지도록된 제품을 도금처리 하는 상관의 제조방법.It is a well-known forging machine in which a circular ring 1 made by a press is automatically transferred into a mold. The punch fixing plate 5 on which the central punch 7 is fixed while the slide 4 descends presses the spring 6. While the center punch (7) is inserted into the inside of the circular ring (1) to center the product and the punch fixing plate (5) is lowered further to press the middle plate (8) and the middle plate (8) again the upper form ( 9) When the upper die 9 presses the spring 15, the outer circumferential surface 2 of the circular ring 1 is compressed to form a trench 2 ', and the inclined crimp portion of the central punch 7 is pressed. 10 is formed in the inclined portion 11 on the inner side of the circular ring and the bush 14, which is firmly attached to the spring 6 in the middle plate 8 and the upper die 9, is pressed on the circular ring. Without any effect, the inner bottom is plated with a product so that a slight rounding is made by the stop pin 12 supported by the spring 13.
