본 발명은 스텐레스스틸제 솔저면에 알미늄주물판을 성형시키는 방법에 관한 것이다.The present invention relates to a method of forming an aluminum casting plate on a stainless steel sole face.

스텐레스스틸은 부식이 되지 않고 표면이 미려하여 가공이 용이할 뿐만 아니라, 경질이어서 음식용기로 많이 이용되고 있으나 한편으로는 열이나 연탄가스 등에 약하고 또 열전도가 빠라 증숙물이 채익기도 전에 밑에 깔려있는 부분은 미리 타버리는 경향이 있어 단일재의 조리용기나 솥으로는 사용이 어려웠으나 근래에 이르러 용기나 솔체의 저면에 구리도금, 알미늄코팅, 또는 알미늄층을 부착하여 상기의 결함을 어느정도 보완시킨 조리용기나 밥솥등이 등장하였다.Stainless steel is not easily corroded and has a beautiful surface, making it easy to process. It is also used as a food container because it is hard. On the other hand, it is weak to heat, briquette gas, and has high thermal conductivity. The part tends to burn out in advance, making it difficult to use as a single cooking vessel or pot, but recently, a cooking vessel that compensates the above defects to some extent by attaching copper plating, aluminum coating, or aluminum layer to the bottom of the container or the sole. Me rice cooker appeared.

그러나 상기와 같이 용기나 솥체저면에 구리도금이나 알미늄코팅을 한다던가 아니면 알미늄층을 접합한 것은 사용중 고열을 반복하여 받음으로써, 도금이나 코팅층등이 스텐레스스틸제인 솔저면과의 열팽창계수가 상이한 관계로 쉽게 박리되어 수명이 매우 짧았던 경향이 있었다.However, copper plating or aluminum coating on the bottom of the container or pot body, or the aluminum layer is bonded, is subjected to repeated high heat during use, so the thermal expansion coefficient of the plating or coating layer is different from that of the stainless steel surface. Easily peeled off tended to have a very short lifespan.

본 발명은 종래 이러한 문제점을 해결하기 위한 것으로서 솔체저면을 형성함에 있어서 스텐레스스틸재 저면을 적당하게 떼어내고 이것에 알미늄판을 형성함으로써 서로 다른 열팽창계수에도 불구하고 결합상태가 오래 지속되도록 한 것이다.The present invention is to solve such a problem in the prior art to form a bottom of the stainless steel material by appropriately peel off and to form an aluminum plate on it so that the bonding state is long lasting despite the different coefficients of thermal expansion.

이의 제작과정을 첨부도면에 의거하여 각 공정법로 상세히 설명하면 다음과 같다.The manufacturing process thereof will be described in detail with each process method based on the accompanying drawings as follows.

제1공정 : 스텐레스스틸재 솔체(1)의 내저면에 돌턱(2)을 형성하고 외저면에는 요입부(3)(4)를 절곡 형성한다. (제1도 참조)First step: A stone jaw 2 is formed on the inner bottom of the stainless steel sole 1, and the recesses 3 and 4 are bent on the outer bottom. (See Figure 1)

제2공정 : 돌턱(2)의 내부에 형성된 솥저면적의 95%정도에 해당되는 절단원판 (1')을 절단제거하여 통공(5)을 천공한다. (제2도 참조)Second step: The through hole 5 is drilled by cutting and removing the cutting disc 1 'corresponding to about 95% of the bottom area of the pot formed inside the stone jaw 2. (See Figure 2)

제3공정 : 통공(5)을 천공한 솥체(1)를 하형틀(6)상에 전도시켜 돌턱(2)이 하형틀(6)의 상면에 잘 밀착되게 재치한 다음(제3도 참조), 그 상부에 주입구(7')가 천공된 상형틀(7)을 설치한다(제4도 참조), 이때 상형틀(7)의 하단연부는 솥에 (1)의 외주연과 밀착되어야 하고 상형틀(7)의 내면과 솥체(1)저면사이에 적당한 간격을 두어야 한다.3rd step: The pot body 1 which drilled the through-hole 5 was inverted on the lower mold 6, and the stone jaw 2 was placed in close contact with the upper surface of the lower mold 6 (see FIG. 3). Install the upper mold 7 with the injection hole 7 'perforated therein (see FIG. 4), wherein the lower edge of the upper mold 7 should be in close contact with the outer periphery of (1) in the pot and Appropriate spacing should be provided between the inner surface of the mold (7) and the bottom of the pot body (1).

제4공정 : 제3공정에서 설치된 상형틀(7)의 주입구(7)에 용융 알미늄(8)을 부어 굳혀서 솥체(1)에 알미늄 주물판(9)을 성형시킨다.4th process: The molten aluminum 8 is poured into the injection hole 7 of the upper mold | type 7 provided in the 3rd process, and it hardens, and the aluminum casting plate 9 is shape | molded in the pot body 1. As shown in FIG.

제5공정 : 제4공정을 거쳐나온 제품의 결합된 부분을 잘다듬고 표면광택처리를 하여 완제품을 만든다.5th process: Finish the finished product by trimming the combined part of the product which went through the 4th process and performing surface gloss treatment.

이상과 같은 제공정을 거쳐 생산되는 본 발명에 의한 스텐레스틸재솥은 알미늄주물판(9)이 솥체의 통공(5)을 관통하고 돌턱(2)과 요입부(3)(4)를 협지한 상태로 성형되어 있어 밀폐도가 완전할 뿐만 아니라 결합력이 강력하고, 또 종래와 같이 서로 상이한 열팽창계수의 영향을 받지 않기 때문에 수명이 장구한 특징을 지닌 것이다.In the stainless steel cooking pot according to the present invention produced through the above-described provision, the aluminum casting plate 9 penetrates the through hole 5 of the pot body and sandwiches the stone jaw 2 and the indentation part 3 and 4. Because it is molded in the form of a seal, it is not only completely sealed but also has a strong bonding force, and is not affected by different thermal expansion coefficients as in the prior art, and thus has a long service life.
