본 발명은 용기 성형시 몸체에 확장팽창율을 크게 할 수 있도록 금속용기의 벌지성형 방법 및 장치에 관한 것이다.The present invention relates to a bulge forming method and apparatus for a metal container so as to increase the expansion expansion ratio in the body when forming the container.

종래의 남비, 주전자, 커피폿트 등의 금속 용기를 성형하기 위해서는 용기몸체 각각의 부위별로 형상을 성형하여 용접연결한후 연마하는 방법으로 용기를 제작하므로서, 여러 단계의 공정을 거쳐야 할뿐만 아니라 작업 시간이 많이 소요되고, 많은 인원이 작업하게 되는 단점이 있어, 이를 해결하기 위한 본원의 선특허출원 제94-32064호에서는 금속본을 유압으로 벌지시켜 용기를 성형하므로써, 용기의 몸체가 일체형으로 형성되므로 부위별로 각각 성형하여 용접할 필요가 없으며, 고품질의 제품을 대량 생산할 수 있는 잇점은 있으나, 이는 용기의 몸체 직경 크기가 고정된 금혀의 크기에 한정되므로 용기의 높이는 동일하게 하고, 몸체의 직경을 크게 확장시키고자 할 경우에는 금속본의 팽창율에 한계가 있어 벌지성형 작업시 터지는 문제점이 있었다.In order to mold metal containers such as pots, kettles, coffee pots, and the like, the containers are manufactured by forming, welding, and polishing the shape of each part of the container body. This takes a lot, there is a disadvantage that a large number of personnel to work, in the prior patent application 94-32064 of the present application for solving this problem by forming a container by hydraulically bulging a metal bone, since the body of the container is formed integrally It does not need to be molded and welded for each part, and there is an advantage to mass production of high quality products. However, since the diameter of the container is limited to the size of the fixed tongue, the height of the container is the same and the diameter of the body is increased. In the case of expansion, there is a problem that the expansion rate of the metal bone is limited, which causes the bulge during the bulge forming operation.

본 발명은 이러한 문제점을 해결하기 위해 안출한 것으로써, 프레스의 받침대 상에 고정되는 금형지지구 저면을 개구시킨 상태로 금형을 삽입하되, 금형은 좌우로 나눠지는 상부 금형과, 상부 금형과 분리되는 하부 금형으로 분할시킨 것으로써, 하부 금형은 프레스 받침대 내에 설치된 3차 실린더의 작동에 따라 상하로 수직 이동되도록 구성하여 금속본 벌지성형 작업시 길이가 같은 금속본을 금형내에 삽입시 하부 금형을 하강시켜 금속본을 삽입시키고, 벌지 작업시에는 프레스 램상의 2차 실린더 가압봉이 금속본 내에 액체를 가압하는 동시에 3차 실린더의 지지봉이 하부 금형을 상승시켜 주므로서 금속본이 상부로 밀리면서 팽창율을 크게 하여 확장되게 한 것으로 본 발명은 용기의 몸체를 길이보다는 용기의 원둘레 직경을 크게 벌지성형할 수 있도록 발명된 것이다.The present invention has been made in order to solve this problem, the mold is inserted in a state in which the bottom of the mold support fixed to the base of the press is opened, the mold is separated from the left and right upper mold and the upper mold As the lower mold is divided into lower molds, the lower mold is configured to move vertically up and down according to the operation of the tertiary cylinder installed in the press pedestal. In the case of bulging operation, the secondary cylinder pressurization rod on the press ram presses the liquid into the metal bone, while the support rod of the tertiary cylinder raises the lower mold while the metal bone pushes upwards to increase the expansion rate. By expanding the present invention, the body of the container can be bulged with a larger diameter around the container than its length. The invention to be.

이하, 첨부 도면에 의거하여 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

상부에 1차 실린더(2)가 고정되고, 하단은 받침대(5)에 고정된 가이드봉(1')상에 1차 실린더(2)의 하강축(2')에 의하여 승하강되는 램(3)을 유착시켜, 램(3)내부에 설치된 2차 실린더(4)의 가압봉(4')이 받침대(5)상의 금형(8)내의 금속본(9)을 가압할 수 있도록 된 프레스에 있어서, 받침대(5)상에 고정되는 금형지지구(7)의 저면을 개구시켜 상부금형(8a)(8b)과 하부금형(8')으로 분할되는 금형(8)을 삽입시키고, 하부금형(8')은 받침대(5)내에 설치된 3차 실린더(6)의 지지봉(6')에 의하여 금형지지구(7)내에서 하부로 승하강될 수 있도록 구성하여 금속본(9)을 금형(8)내에 인입시 3차 실린더(6)의 지지봉(6')이 하부금형(8')을 하부로 수직하강시켜 금속본(9)을 금형(8)내에 위치시킨후 램(3)이 하강되어 2차실린더(4)의 가압봉(4')이 금속본(9)내의 액체(10)를 가압하는 동시에 3차 실린더(6)의 지지봉(6')이 하부금형(8')을 타격 승강시켜 금속본(9)이 상부로 밀리면서 벌지되도록 한 용기의 벌지방법이다. 미설명부호 11은 용기이며, 12는 금속본 및 금형지지구를 고정할 수 있도록 된 지지실린더이다.The primary cylinder (2) is fixed to the upper portion, the lower end of the ram (3) is lowered by the lowering shaft (2 ') of the primary cylinder (2) on the guide rod (1') fixed to the pedestal (5) In the press in which the pressure rod 4 'of the secondary cylinder 4 installed in the ram 3 can press the metal main body 9 in the mold 8 on the pedestal 5, , The bottom of the mold support 7 fixed on the pedestal 5 is opened to insert the mold 8 divided into the upper mold 8a, 8b and the lower mold 8 ', and the lower mold 8 ') Is configured to be lowered in the mold support (7) by the support rod (6') of the tertiary cylinder (6) installed in the pedestal (5) to form the metal bone (9) to the mold (8) When drawing in, the support rod 6 'of the tertiary cylinder 6 lowers the lower mold 8' vertically to position the metal bone 9 in the mold 8, and then the ram 3 is lowered. The pressure rod 4 'of the vehicle cylinder 4 presses the liquid 10 in the metal bone 9 and at the same time By striking the support bar (6 ') have a lower mold (8') of the cylinder (6) lifting the bulge method of the vessel such that the metal while the bulge 9 is a top mm. Reference numeral 11 denotes a container, and 12 denotes a support cylinder for fixing the metal bone and the mold support.

이와같이 실시되는 본 발명은, 먼저 성형하고자 하는 용기(11)의 크기에 알맞도록 금속판을 재단하여형의 금속본(9)을 1차 성형한 다음 유압프레스(1)의 받침대(5)상에는 지지실린더(12)에 고정지지된 금형지지구(7)내에 상부금형(8a)(8b)과 하부금형(8')으로 분리되는 금형(8)을 삽입시킨후 금형(8)내에 금속본(9)을 인입시키되, 받침대(5)내에 설치된 3차 실린더(6)의 지지봉(6')을 하강시켜 하부금형(8')을 하향 이동시킨 다음 금속본(9)을 금형(8)내에 제2도와 같이 위치시켜 내부에 액체(10)를 충만시키면 벌지성형 작업 준비가 완료된다.The present invention is carried out in this way, first by cutting the metal plate to fit the size of the container 11 to be molded The metal mold 9 of the die is first molded, and then the upper mold 8a and 8b and the lower part in the mold support 7 fixed to the support cylinder 12 on the pedestal 5 of the hydraulic press 1. After inserting the metal mold 8 separated into the metal mold 8 ', the metal body 9 is inserted into the metal mold 8, and the supporting rod 6' of the tertiary cylinder 6 installed in the pedestal 5 is lowered. The lower mold 8 'is moved downward, and then the metal bone 9 is placed in the mold 8 as shown in FIG. 2 to fill the liquid 10 therein, thereby preparing for the bulge forming operation.

이렇게 용기(11)를 성형하기 위한 금속본(9)의 벌지 작업 준비가 완료되면 프레스(1)의 작동 스위치를 조작하여 1차 실린더(2)의 하강축(2')을 하강시키면 가이드봉(1')에 유착된 램(3)이 하강되어 받침대(5)상의 금형지지구(7)와 대응되도록 한후 램(3)내부에 2차 실린더(4)의 가압봉(4')을 하강시켜 금속본(9)내의 액체(10)를 가압하는 동시에 받침대(5)의 3차 실린더(6)의 지지봉(6')이 하부금형(8')을 서서히 상승시키면 금속본(9)은 저부에서 부터 상부로 밀리므로 외주면이 상하로 수축되려는 동시에 상부에서 가압봉(4')이 액체(10)를 가압하므로서 금속본(9)은 점차로 확장팽창되어 제3도와 같이 벌지성형되어 용기(11) 모양이 된다.When the bulging operation of the metal bone 9 for forming the container 11 is prepared in this manner, the operation switch of the press 1 is operated to lower the lower shaft 2 'of the primary cylinder 2 so that the guide rod ( 1 ') and the ram 3 is lowered to correspond to the mold support 7 on the pedestal 5, and then the pressure rod 4' of the secondary cylinder 4 is lowered inside the ram 3 When the support rod 6 'of the tertiary cylinder 6 of the pedestal 5 gradually raises the lower mold 8' while pressing the liquid 10 in the metal bone 9, the metal bone 9 is removed from the bottom. Since the outer circumferential surface is to be contracted up and down from the upper side from the upper side, while the pressure rod 4 'presses the liquid 10 from the upper side, the metal bone 9 is gradually expanded and bulged to form a bulge as shown in FIG. Becomes

이때, 금형지지구(7)내에 삽입되는 상부금형(8a)(8b)의 외면과 금형지지구(7)내면은 서로 대응되도록 미세하게 상광하협형으로 경사를 이루고 있으므로 상부금형(8a)(8b)은 금형지지구(7) 상부내에서 하부로 이탈이 발생되지 않고 지지된 상태를 유지하며, 하부금형(8') 외면과 하부금형이 위치하는 금형지지구(7) 하측 내주면은 상부 금형이 삽입된 하단 지점부터 아래로 수직각을 이루고 있어, 금형지지구(7)내에서 하부금형(8')의 승하강 운동이 자유롭게 되도록 한 것이다.At this time, the outer surface of the upper mold (8a) (8b) and the inner surface of the mold support (7) inserted into the mold support (7) is inclined in a fine light and down narrow so as to correspond to each other, the upper mold (8a) (8b) In the upper part of the mold support (7) is maintained without being released to the lower side without the occurrence of the lower mold (8 ') and the lower inner peripheral surface of the lower mold support (7) where the lower mold is located. The vertical angle is made downward from the inserted lower end point, so that the lifting and lowering motion of the lower mold 8 'is freely made in the mold support 7.

또한, 본 발명은 용기(11)의 성형시 하부금형(8')내벽에 무늬모양의 요철을 형성시켜 금속본(9)을 벌지하면 용기(11) 몸체의 하부외면에 무늬 모양을 성형시킬 수 있게 된다.In addition, the present invention can form a pattern on the bottom outer surface of the body of the container 11 by forming a pattern-shaped unevenness on the inner wall of the lower mold 8 'to bulge the metal bone 9 when forming the container 11. Will be.

이와같이 본 발명은 남비, 주전자, 커피폿트 등의 몸체를 크게 확장시켜 원하는 크기의 제품을 얻을 수 있게 됨은 물론 별도의 작업 공정이 필요없이 동일한 생산라인으로 간단용이하게 고품질의 용기를 성형시킬 수 있게 된 것이다.In this way, the present invention can greatly expand the body of the pot, kettle, coffee pot, etc. to obtain a product of a desired size, as well as to easily form a high-quality container in the same production line without the need for a separate work process. will be.
