Abstract

Method for manufacturing an aluminum kitchen ware consists of (i) forming a ware body by deep-drawing the aluminium ware material in the conventional metal mould, and (ii) forming an upper rim of the ware body in the metal mould including the protruded round part of which the inner diameter is somewhat smaller than the outer diameter of the formed ware body. In the finished ware, the thickness of the upper rim is equal to that of the bottom face.

본 발명은 주로 알미늄 강판을 소재로하여 프레싱 공정으로

Figure kpo00001
형의 용기체를 압형하여 각종 프라이팬, 남비등 주방용품용 제조함에 있어서 프레싱 금형의 특징적인 설계 구조에 의하여 용기의 상주연 윤곽테가 용기 밑바닥과 동일한 재료 두께를 유지하면서 측면부 상측 외주연에 규칙적인 단입턱을 형성하므로서 용기의 외관미를 일층 개성하여 제품을 보다 고급화 할 수 있도록 한 알미늄 주방용기의 성형 방법에 관한 것이다.The present invention mainly uses aluminum steel sheet as a pressing process
Figure kpo00001
In the manufacturing of various types of frying pans, pots, and other kitchen utensils by pressing the container body, the characteristic design structure of the pressing mold maintains the same material thickness as the bottom of the container while maintaining the same material thickness as the bottom of the container. The present invention relates to a method of forming an aluminum kitchen container, by forming a stepped jaw, to further enhance the product by personalizing the outer appearance of the container.

지금까지 알미늄 강판을 프레싱 공정으로 압형하여 성형하는 각종 주방 용기는 프레싱 과정에서 용기의 벽면부가 단순히 상향으로 절곡되는데 그치는 단순한 수직평면식 외형 구조였으며 이러한 구조는 벽면이 프레싱되는 과정중 그판면의 구께가 프레싱 압력을 받지 않는 바닥면의 두께보다는 다소 얇아진 산태 그대로 시각상 상주연 가장자리가 표면에 나타나 보이기 때문에 실제는 두꺼운 소재 알미늄판을 사용하여 제품화하는 데도 불구하고 완성된 제품은 외관상 얇은 강판제를 사용한 것과 같이 비교적 약하게 보이게 되어 제품의 신뢰성을 저하 시키고 또한 그 외관미도 단조로운 결점이 있었다.Until now, various types of kitchen containers, which are formed by pressing aluminum sheet by pressing process, have simply bent upward in the wall part of the container during the pressing process, and this structure has been a simple vertical plane external structure. Since the edges appear visually on the surface as it is slightly thinner than the thickness of the floor that is not subjected to pressing pressure, the finished product is made of thin steel sheet in appearance despite the fact that it is made of thick aluminum plate. As it looks relatively weak, it lowers the reliability of the product and its appearance is also monotonous.

본 발명은 이러한 종래까지의 알미늄 강판제의 주방 용기가 갖는 결점을 개선하여 일차 성형된 용기체를 벽면 성형을 위한 2차 금형을 사용하여 프레싱 하므로서 용기체의 상주연을 본래의 재료두께로 유지시키는 조건하에서 용기체의 외주연측에 제품의 외관미를 개선할 수 있는 단입부를 동시에 형성시킬 수 있도록 하여 종래의 주방 용기보다 외관상 제품의 신뢰성을 높힐 수 있는 상품 가치를 향상시킬 수 있도록 한것인바, 이하 본 발명의 성형 방법을 공정도를 나타낸 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention improves the shortcomings of the conventional kitchen plate made of aluminum steel sheet to press the primary molded container body by using a secondary mold for wall forming to maintain the circumferential edge of the container body at the original material thickness. Under the conditions, the outer periphery of the container body can be formed at the same time the indentation that can improve the appearance of the product to improve the product value that can enhance the reliability of the product in appearance than conventional kitchen containers, Hereinafter, the molding method of the present invention will be described in detail with reference to the accompanying drawings showing process drawings.

제1도는 본 발명 방법에 의하여 성형된 제품의 외형도로서 용기체(1)의 상주연 윤관테(2)의 재료 두께(a)를 바닥면(4)의 재료두께(a')와 동일한 두께를 유지시키면서 벽면부(1c)의 두께(b)를 약간 압연 및 연신하여 단입부(3)을 부여시키는 것으로, 본 발명은 제2도와 같은 용기(1)를 성형시킴에 목적이 있다.1 is an external view of a product molded by the method of the present invention, the material thickness (a) of the circumferential peripheral rim of the container body (1) is equal to the material thickness (a ') of the bottom surface (4) The present invention aims at forming the container 1 as shown in FIG. 2 by slightly rolling and stretching the thickness b of the wall surface portion 1c while maintaining the shape.

이의 성형방법을 제3도 및 제4도의 나뉘어진 성형 공정에 따라 설명한다.Its molding method will be described according to the divided molding process of FIG. 3 and FIG.

Figure kpo00006
The outer circumferential side outer diameter w of the mold container material 1b and the inner diameter wb of the protruding annular portion 9 of the secondary molding die 8 are correlated with each other as shown in FIG.

즉 2차 성형금형(8)의 도입부(8a)의 내경(wa)은 용기체(1b)의 외경(w)과 동일한 규격으로 하고 돌출환부(9)는 상측 모서리(9a)를 각면으로 형성하여 일정한 돌출 두께(9b)을 가지므로서 돌출환부(9)의 내경(wb)은 용기체(1b)의 상주연 외경보다 약간 협소한 규격으로 된다.That is, the inner diameter wa of the introduction portion 8a of the secondary molding die 8 is the same as the outer diameter w of the container body 1b, and the protruding annular portion 9 forms the upper edge 9a on each side. The inner diameter wb of the protruding annular portion 9 is slightly narrower than the outer peripheral outer diameter of the container body 1b while having a constant protruding thickness 9b.

즉 돌출환부(9)의 돌출두께(9b)를 용기체(1b)의 재료두께(a)의

Figure kpo00007
을 넘지 않도록 적당한 규격으로 설정한다.That is, the protrusion thickness 9b of the protruding annular portion 9 is determined by the material thickness a of the container body 1b.
Figure kpo00007
Set the proper size so as not to exceed.

이러한 규격을 갖는 2차 성형금형(8)에 제4(a)도와 같이 t1 형 용기소재(1b)를 일치하면 용기소재(1b)의 외경이 2차 성형금형(8)의 도입부(8a)와 일치되게 삽입되면서 돌출환부(9)위에 올려놓아진다. 이상태에서 가동금형(7)을 하향으로 이동시켜 프레싱하면 돌출환부(9)의 내경 상부측 모서리(9a)가 용기소재(1b)의 벽면(2b)을 설정된 두께(9b)로 잠식하면서 압연되어 용기소재(1b)와 바닥면(4)은 강제적으로 제4(b)도와 같이 미렬 내려와 상측 가장자리의 윤곽테(2)가 일정한 높이(H)로 형성되는 시점에서 하강을 정지하므로서 2차 성형이 끝난다.When the t1 type container material 1b is matched with the secondary molding mold 8 having such a standard as shown in FIG. 4 (a), the outer diameter of the container material 1b is equal to the introduction portion 8a of the secondary molding mold 8. While being inserted in conformity, it is placed on the protruding annulus 9. In this state, when the movable mold 7 is moved downward and pressed, the inner diameter upper edge 9a of the protruding annular portion 9 is rolled while encroaching the wall surface 2b of the container material 1b to a set thickness 9b. The material 1b and the bottom surface 4 are forcibly lowered as shown in the fourth (b), and the secondary molding is completed by stopping the lowering at the time when the contour frame 2 of the upper edge is formed at a constant height H. .

이어 제4(b)도의 상태에서 가동금형(7)를 상승시켜 용기 소재(1b)를 탈형하면 제2도와 같이 상주연 윤곽테(2)가 바닥면(4)과는 동일한 두께로 유지되면서 백면의 외주연은 단입부(3)가 밖으로 뚜렷하게 나타나 보이는것이다.Subsequently, when the movable mold 7 is raised in the state of FIG. 4 (b) to demold the container material 1b, the upper peripheral edge 2 is maintained at the same thickness as the bottom surface 4 as shown in FIG. The outer periphery of is that the indentation (3) is clearly visible outward.

이와 같이 성형된 용기테(1)는 표면 도장작업과 손잡이부착, 두껑 결합등의 2차 가공처리에 의해 제4(a)도와 같은 완제품이 얻어진는 것으로 이의 완제품은 상주연 가장자리의 두께가 원래의 재료 두께로서 그대로 유지되어 외관상 표면에 뚜렷이 나타나 보이므로서 제품의 견고성이 돋보이고 그로 인해 제품의 신뢰성이 보강되며 특히 벽면의 외주연측에 단입부(3)가 규칙적으로 형성되므로서 외관미가 일측 더 미려하게 되는 것이다.The container frame 1 thus formed has a finished product as shown in Fig. 4a by secondary processing such as surface coating work, handle attachment, and lid coupling, and the finished product has the thickness of the peripheral edge of the original material. It is maintained as a thickness and is clearly visible on the surface, which shows the robustness of the product, thereby reinforcing the reliability of the product. Will be done.

이때 2차 성형 금형(8)의 돌출환부(9)의 상면을 파상형이나 용절부등 적절히 변형을 가하여 설계하면 성형 된 단입부(3)의 외형이 그에 상응하여 파상형이나 요철상으로 성형될 수가 있어 다양한 외관미를 갖는 제품을 얻을 수도 있다.At this time, if the upper surface of the protruding annular portion 9 of the secondary molding die 8 is designed by appropriately deforming a wave shape or a welded portion, the external shape of the molded indentation part 3 can be formed into a wave shape or irregularities accordingly. It is also possible to obtain a product having a variety of appearance taste.

이상과 같이 본 발명은 성형돌출부(9)를 갖는 2차 성형금형(8)을 이용하여 용기체를 프레싱하므로서 주방용기의 사품가치를 일층 더 개선시킨 효과가 있다.As described above, the present invention has the effect of further improving the value of the product of the kitchen container by pressing the container body by using the secondary molding mold 8 having the molding protrusion 9.
