본 발명은 주전자등 금속 용기의 몸체 성형 및 몸체에 무늬 모양과 각(角)을 성형하는 주전자의 몸체 성형 방법에 관한 것이다.The present invention relates to a body forming method of a metal container such as a kettle and a body shaping method of a kettle for shaping a pattern shape and an angle to a body.

종래의 금속 주전자는 몸체 각각의 부위별로 형상을 성형하여 용접 연결하는 방법으로 하나의 주전자를 완성하였다.In the conventional metal kettle, one kettle was completed by forming a shape for each part of the body by welding.

이렇게 하나의 주전자를 완성하기 위해 여러 단계의 복잡한 공정을 거쳐 용접후 다시 연마함으로서, 연마시 용접 부의에 결함이 나타나는 경우가 종종 발생하여 제품을 사용하지 못하고 버려지므로 재료의 낭비와 성형작업 및 용접에 소요되는 시간이 많은 문제점이 있었다.In order to complete one kettle, after complex welding process, it is polished again after welding. When polishing, defects in welding parts often occur. The time spent was a lot of problems.

본 발명은 이러한 문제점을 해결하기 위해 창안된 것으로써, 주전자 내부에 대응되는 모형을 조립체로 형성하여 주전자 몸체 성형시, 원재료인 금속판을 관으로 형성한후 금속관 내부에 금형을 삽입하여 외면에는 로울러로 로울링하여 몸체를 성형하므로서 연마시 용착 부위의 결함으로 인하여 버려지는 재료의 낭비를 방지하고, 주전자의 성형 공정을 간단 용이하게 할 수 있도록 된 것이다.The present invention has been devised to solve this problem, when forming a model corresponding to the inside of the kettle as an assembly, when forming the kettle body, forming a metal plate as a raw material into a tube and then inserting a mold inside the metal tube into a roller on the outer surface By forming the body by rolling, it is possible to prevent waste of materials that are discarded due to defects in the welded portion during polishing and to simplify the molding process of the kettle.

이하, 첨부 도면에 의거하여 본 발명의 실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[실시예 Ⅰ]Example I

원재료 금속판(1)을 주전자(2)의 크기에 대응되도록 재단하여 상협하광 되도록 금속관(3)을 형성하여 상·하 분리되는 모형을 갖은 금형(5)에 삽입시켜 금속관(3) 외주면을 로울러(6)로 로울링하여 일정한 형태의 형상을 성형후 하단부를 별도의 금형(7)에 삽입 압착하여 주전자의 몸체(2')를 완성한후 저면을 원형금속판(8)으로 용접한 다음 연마하는 것이다.The raw material metal plate 1 is cut to correspond to the size of the kettle 2, and the metal tube 3 is formed so that the upper and lower light beams are inserted into a mold 5 having a model that is separated from the top and the bottom, so that the outer peripheral surface of the metal tube 3 is rolled ( 6) After rolling to form a shape of a certain shape by inserting and pressing the lower end in a separate mold (7) to complete the body (2 ') of the kettle, the bottom surface is welded with a circular metal plate (8) and then polished.

이와 같은 본 발명을 제1도에 의하여 간단히 요약하면, 원재료 금속판(1), 상협하광 금속관(3)형성, 금형(5)삽입, 로울러(6)로 로울링, 금형(7)에 압착, 원형 금속판(8)용접, 연마, 완제품의 공정 단계를 갖게 된다.Briefly summarized according to the present invention according to Figure 1, the raw material metal plate (1), the upper and lower down light metal tube (3) formation, the mold (5) inserting, roller (6) rollers, pressed to the mold (7), circular The metal plate 8 has a process step of welding, polishing and finished products.

[실시예2]Example 2

원재료 금속판(1)을 금속관(3')으로 형성한후 금속관(3')내부에 상·하분리되는 금형(5)을 삽입하여 로울러(6)로 로울링하여 주전자(2)의 상부 몸체(2a)를 형성하고, 원형 금속판(1')을 구형 금형(7')에 가입하여 하부 몸체 (2b)를 성형하여 상부 몸체(2a)와 하부 몸체 (2b)를 용접후 연마하는 구성이다.After forming the raw material metal plate 1 into the metal tube 3 ', a mold 5, which is separated up and down, is inserted into the metal tube 3' and rolled with a roller 6 to form the upper body of the kettle 2 ( 2a), the circular metal plate 1 'is joined to the spherical mold 7', and the lower body 2b is formed to weld and polish the upper body 2a and the lower body 2b after welding.

[실시예3]Example 3

원재료 금속판(1)을 U형 금속관(3)으로 형성하고, 금속관(3) 내부에 조합분리형의 금형(5')을 삽입하여 U형 금속관(3) 외면을 로울러(6)로 로울링하여 일체로 된 몸체(2')를 성형후 연마하여 주전자(2)를 완성하는 것이다.The raw metal plate 1 is formed of a U-shaped metal tube 3, and a combination-type mold 5 'is inserted into the metal tube 3 to roll the outer surface of the U-shaped metal tube 3 with a roller 6. Polishing after molding the body (2 ') to complete the kettle (2).

[실시예4]Example 4

주전자(2) 형태의 몸체 (2')를 성형한후 무늬가 양각으로 형성된 하부 금형(5)에 주전자의 몸체(2')를 삽입한후, 이와 대응되도록 설치되어 있는 무늬가 음각으로 형성되어 었는 상부 프레스 금형(9)으로 압착하여 몸체 (2')에 무늬 모양과 각을 형성할수 있도록 된 구성이다.After molding the body 2 'of the shape of the kettle 2, the body 2' of the kettle is inserted into the lower mold 5 in which the pattern is embossed. The upper press mold 9 is pressed to form a pattern shape and angle on the body 2 '.

이와 같이 본 발명은 원재료 금속판(1)을 굼속관(3)(3') 형성한후 이에 삽입 대응되도록 상·하 분리되는 주전자(2) 형태의 금형(5)(7)에 삽입시켜 로울러(6)로 로울링하므로서 주전자의 몸체(2') 성형이 간단하고, 용접 부위가 제1도와 같이 저면에 대응되는 원형 금속판(8) 또는 제2도와 같이 상부 몸체(2a)와 하부 몸체 (2b)만을 용접하므로서, 연마시 용접 부위의 결함으로 성형된 몸체를 버려야 하는 문제점을 방지함은 물론, 제3도와 같이 원재료 금속판(1)을 U형 금속관(3)으로 형성하여 조합분리형의 금형(5')을 삽입한후 하단부로부터 로울러(6)로 로울링함으로서 주전자 몸체(2')의 성형시 용접을 하지 않고, 일체형으로 성형할수도 있게 된다.Thus, in the present invention, the raw material metal plate 1 is formed by the rollers (3) (3 ') and then inserted into the molds (5) (7) in the form of kettles (2) separated up and down to correspond to the insertion. 6) The molding of the body 2 'of the kettle is simple by rolling, and the upper part 2a and the lower body 2b as shown in FIG. By welding only, it prevents the problem of discarding the molded body due to defects in the welded part during polishing, as well as forming the raw metal plate 1 into the U-shaped metal tube 3 as shown in FIG. By inserting the roller into the roller 6 from the lower end, the kettle body 2 'can be molded in one piece without being welded when forming.

이렇게 된 본발명은 주전자 성형 공정 단계를 대폭 감소화하여 성형 작업을 자동화 시스템으로 전환함에 따라, 인건비를 줄이고, 제품을 대량 생산하여 고품질의 제품을 저렴한 가격에 제공할 수 있게 된 효과를 갖게 되었다.This invention has greatly reduced the kettle molding process step to convert the molding operation to an automated system, thereby reducing labor costs, mass production of products to provide high-quality products at low prices.
