Description
본 발명은 청동유기 칼의 제조방법에 관한 것으로, 더욱 상세하게는 구리와 주석을 합금한 청동에 니켈과 망간을 미량 혼합되게 하여 칼의 칼날 부분에 적당한 경도를 유지한 상태에서 절삭력과 내마모성을 유지하는 주방용 칼을 제조함으로써, 음식물과 접촉되는 칼날을 살균(殺菌), 항균(抗菌), 무독(無毒)의 기능을 할 수 있는 무공해 금속으로 형성하여 위생적인 음식문화를 즐길 수 있도록 한 청동유기칼의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a bronze organic knife, and more particularly, to a method for manufacturing a bronze organic knife, which comprises mixing a nickel and a manganese in a bronze alloy of copper and tin to maintain a cutting force and a wear resistance while maintaining an appropriate hardness Which is made of pollution-free metal that can function as sterilization, antibacterial, and non-toxic by making a kitchen knife that is in contact with food, so that a hygienic food culture can be enjoyed. And a method for producing the same.
일반적으로, 청동유기는 구리 78% 내외에 주석 22% 내외의 중량비로 혼합하여 된 합금으로써 인체에 무해한 특성으로 인하여 오래전부터 식자재인 놋그릇이나 수저를 생산하여 각종 식생활에 적용하였으며 또한 가공이 용이하여 생활도구로 널리 사용되어 왔다.Generally, bronze organic is alloyed with 78% of copper and 22% of tin by weight. It is harmless to human body and it has long been used as food material for brassware and soup. Has been widely used as a tool.
청동유기로 제조된 그릇은 살균효과와 더불어 독성물질에 반응하면서 음식 맛을 살려주는 기능은 물론 상추나 채소를 담아 보관하였을 때 일반 냉장보관보다 오랫동안 싱싱함을 유지하는 기능성을 갖추고 있음이 밝혀졌으며,Bronze organic cookware has a function to maintain freshness for a long period of time compared to general refrigeration storage when stored with lettuce or vegetables, as well as a function to restore food taste in response to toxic substances as well as sterilizing effect.
학계의 보고에 의하면, 놋쇠가 식중독균을 99.9%나 제거한다는 연구결과와 더불어 "200ℓ 들이 수족관에 놋그릇이나 놋수저의 재료인 놋쇠 판(가로×세로 30cm)을 넣은 결과, 40여 시간 뒤 생선에서 비브리오균이 99.9% 제거됐고, 조개류 속 비브리오균도 48시간이 지나자 90%가 사라졌다" 는 실험결과가 알려지면서 전통 놋그릇(청동유기 그릇)에 새삼 관심이 쏠리고 있다.According to a report by the academy, "Brass has removed 99.9% of food poisoning bacteria," and added, "As a result of putting a brass plate (30cm x 30cm) of brassware or brassware into a 200-liter aquarium, 99% of bacteria were eliminated, and 90% of Vibrio bacteria in shellfishes disappeared after 48 hours. "As a result of the experiment, it is said that traditional brassware (bronze organic bowl) is attracting attention.
청동유기 제품은 구리와 주석이 78:22의 비율로 혼합된 합금으로서, 특히 방짜유기의 경우에는 합금의 비율이 다르거나 불순물이 섞일 경우 1차 성형물을 원하는 형상으로 두드리는 과정에 깨어지는 현상이 발생되었고 다른 한편으로는 경도가 약하게 되어 제품이 요구하는 기준에 미달되는 사례 등이 있었다.Bronze organic products are mixed with copper and tin at a ratio of 78:22. Especially, in the case of organic raw materials, when the proportion of the alloy is different or the impurities are mixed, the primary molding is broken in the process of tapping into the desired shape. On the other hand, there were cases where the hardness became weak and the product did not meet the required standards.
상기 청동유기의 합금 특성을 고려하여 양질의 구리와 주석을 정확한 비율로 혼합하여 방짜유기를 제조할 경우, 그릇이나 일반 생활용구 등은 대부분 품질 기준을 만족하였다.Considering the alloying characteristics of the bronze organic material, when the fine copper and the tin were mixed at an exact ratio to prepare the organic material, most of the dishes and the general living equipment satisfied the quality standards.
그러나 상기 조건의 청동유기로 음식물을 다루는 주방용 칼을 제조할 경우에 칼의 경도가 약하였으므로 칼날을 예리하게 가공할 수는 있으나 경도가 약하고 내마모성이 대단히 취약하여 칼날이 쉽게 손상되는 문제점이 있었다.However, in the case of manufacturing a kitchen knife for handling foods by the above-mentioned conditions, since the hardness of the knife is weak, it is possible to sharpen the blade, but the knife is weak and the wear resistance is very weak.
종래의 선출원된 특허등록출원된 것을 살펴보면,As for a patent application filed in the prior art,
10-2015-0095229가 있었으나 이를 구체적으로 살펴보면 구리와 주석을 넣어 청동유기를 만들고 여러 개의 청동유기판을 만들어 이를 겹쳐 압연과 단조를 하여 더욱 단단한 청동유기제품을 만들었다.10-2015-0095229. However, if we look at this in detail, we made copper and tin to make bronze organic and made several bronze organic plates, rolled and forged to make harder bronze organic products.
이와 같은 방법은 칼의 경도를 높일 수는 있으나 여러 개의 청동유기판을 하나의 몸체로 만들기 위해 압연공정, 단조공정을 거쳐야 하는 번거로운 작업공정이 필요하여 제작원가를 높이는 문제점이 있었다.Such a method can increase the hardness of the knife, but it requires a complicated work process requiring a rolling process and a forging process in order to make a plurality of bronze organic plates into a single body, which raises the production cost.
본 발명은 위와 같은 종래의 청동유기로 칼을 제조할 때 칼날의 경도를 높여 칼을 장시간 사용하여도 칼날이 쉽게 마모되지 않도록 하고 제작과정을 단순화하여 제작원가를 줄일 수 있도록 한 것으로, 그 목적은 청동유기를 구성하는 합금의 특성을 유지하면서 이에 내마모성을 부여하여 주방용 칼의 경도를 만족할 수 있는 청동유기칼의 제조방법을 제공하는 것이다.The object of the present invention is to increase the hardness of the blade in manufacturing the conventional bronze organic knife as described above so that the knife is not easily worn even when the knife is used for a long time and the manufacturing process is simplified, The present invention provides a method of manufacturing a bronze organic knife which can satisfy the hardness of a kitchen knife by imparting abrasion resistance thereto while maintaining the characteristics of an alloy constituting bronze organic matter.
이러한 목적을 달성하기 위한 본 발명은, 구리와 주석을 합금한 청동에 니켈과 망간을 미량 혼합되게 칼의 경도를 높이는 모재를 얻고 압연공정과 단조공정을 하여 칼의 형태로 만들며 열처리공정과 연마공정을 거쳐 칼의 제조를 완성함으로써, 칼날의 경도를 높여 칼날의 마모를 줄일 수 있으며 칼을 장시간 사용하여도 칼날이 쉽게 마모되지 않도록 발명한 것이다.In order to accomplish the above object, the present invention provides a base material for increasing the hardness of a knife by mixing a small amount of nickel and manganese into bronze alloyed with copper and tin, rolling and forging to form a knife, The knife is finished to be manufactured. Thus, the hardness of the blade can be increased to reduce the wear of the blade, and the blade is not easily worn even when the knife is used for a long time.
이와 같은 본 발명의 청동유기 칼 및 그의 제조방법은 청동유기에 니켈과 망간을 투입하여 칼날의 경도를 높이도록 하고 제작공정을 단순화하여 제작원가를 줄일 수 있도록 하며 칼날에 묻어나는 세균이 번식을 못하도록 억제하도록 하여 매우 위생적으로 주방용 칼을 제작할 수 있도록 한 것이다.The bronze organic knife of the present invention and the method of manufacturing the same according to the present invention can increase the hardness of the blade by injecting nickel and manganese into the bronze organic material and simplify the manufacturing process to reduce the manufacturing cost and prevent the bacteria So that the kitchen knife can be manufactured very hygienically.
또한 청동유기제품의 고풍스러운 멋을 연출할 수 있어 음식용 식기로 고품격의 멋을 자아낼 수 있도록 한 것이다.In addition, it can produce old-fashioned style of bronze organic products, so that it can produce high-quality fashion with food utensils.
