다중금속 주방용구의 제조방법 및 그의 제조장치{A fabrication method of multi-layer metal bowl and fabrication apparatus thereof} A fabrication method of multi-layer metal bowl and fabrication apparatus

본 발명은 다중금속층을 갖는 주방용구의 제조기술에 관한 것으로, 특히 단일금속으로 주조 또는 성형된 주방용구에 다수의 금속을 선택적으로 용사코팅하여 표면강도, 열전도, 내식성 등의 특성을 강화하고 또한 주방용구의 표면 디자인을 다양한 패턴이나 유형으로 설계할 수 있는 보울형 다중금속 주방용구의 제조방법과 그의 제조장치에 관한것이다.The present invention relates to a manufacturing technique of a kitchen utensil having a multi-metal layer, and in particular, by spraying a plurality of metals selectively on the kitchen utensils cast or molded with a single metal to enhance the characteristics such as surface strength, heat conductivity, corrosion resistance and The present invention relates to a method of manufacturing a bowl-type multimetal kitchen utensil capable of designing a surface design of a tool in various patterns or types, and an apparatus thereof.

대부분의 주방용기는 가공이 용이하고 가격이 저렴하면서 내구성이 보장되는 스테인레스강, 알루미늄, 구리 등의 합금을 이용하여 다층구조로 제작된다. 주방가구에 다중구조의 합금을 이용하는 이유는 단일금속의 취약성을 보강하기 위한 것으로 내마모성, 내화학성, 내부식성 및 미려한 외관을 충족시켜주기 위함이다.Most kitchen containers are manufactured in a multilayer structure using alloys such as stainless steel, aluminum, and copper, which are easy to process, low in cost, and durable. The reason for using multi-structured alloys in kitchen furniture is to reinforce the fragility of single metals to satisfy wear resistance, chemical resistance, corrosion resistance and beautiful appearance.

이러한 다중구조의 주방용구는 그 원자재인 판재에 원하는 특성을 얻기 위한 이종금속을 적층 합금하고 이렇게 합금된 판재를 가공하여 다양한 형상을 갖는조리 및 음식저장용 주방용구를 성형하는 것으로 제작된다.Such multi-layer kitchen utensils are manufactured by laminating and alloying dissimilar metals to obtain desired properties on a plate, which is a raw material, and processing the alloyed plates so as to form cooking and cooking utensils having various shapes.

그런데 다중금속 합금의 주방용구는 성형전 판재의 합금성분에 의해 기본특 성이 결정되어 제작되므로 주방용구의 생산라인에서 제품의 특성을 변경시키는 것은 매우 곤란하여 하나의 생산라인에서 다양한 합금특성의 주방용구를 제작하는 것은 현실적으로 불가능하였다.By the way, the kitchen utensils of multi-metal alloys are produced by determining the basic characteristics by the alloying elements of the plate before molding, so it is very difficult to change the characteristics of the products in the production line of kitchen utensils. It was practically impossible to make a tool.

그러나 위와 같은 선행 발명기술은 합금판재에 의해 성형된 주방용기의 바깥쪽으로 경질의 금속을 다이캐스팅하고 있어 별도의 성형용 금형이 요구되므로 주방용기의 제작단가가 상승하게 되고 공수가 증가되어 생산성이 떨어지는 단점을 가지게 된다.However, the prior art as described above dies hard metal to the outside of the kitchen vessel formed by the alloy plate, so a separate molding die is required, which increases the manufacturing cost of the kitchen vessel and increases the number of times, resulting in lower productivity. Will have

첨부한 도면을 참고로 하여 본 발명을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 적용된 이종금속 용사코팅장치의 개념도로서 직류전원을 이용하여 합금용 와이어의 종단부에서 아크가 일어나 해당 와이어가 용융되게 하고 이렇게 용융된 금속와이어는 노즐을 통해 분사되는 고압에 의해 전방으로 스프레이되게 구성하고 있다.1 is a conceptual view of a dissimilar metal thermal spray coating apparatus applied to the present invention by using a direct current power supply arc to the arc of the alloy wire to melt the wire is melted by the high pressure that the metal wire is sprayed through the nozzle It is configured to be sprayed forward.

이를 구체적으로 살펴보면, 와이어릴(20)로부터 공급되는 와이어(12,13)는 구동장치(10)내의 구동롤러(11)에 의해 각각 도관(14,15)에 안내된다. 이처럼 도관을 따라 안내된 와이어(12,13)는 그 도관(14,15)의 단부에서 노출되게 서로 맞닿게 되는데 이들 도관에는 각각 +,-극성의 직전원케이블(16,17)를 통해 직류전류가 공 급되고 있는 상태이므로 상기 와이어가 맞닿는 부분에서 아크(19)가 일어나게 된다.In detail, the wires 12 and 13 supplied from the wire reel 20 are guided to the conduits 14 and 15 by the driving roller 11 in the driving device 10, respectively. The wires 12 and 13 guided along the conduit are brought into contact with each other so as to be exposed at the ends of the conduits 14 and 15, which are connected to each other by direct current cables 16 and 17 with positive and negative polarity. Since the state is being supplied is the arc 19 occurs in the portion where the wire abuts.

아크의 발생에 의해 와이어는 용융되게 되고 이때 고압노즐(18)을 통한 고압이 상기 용융물을 전방으로 분사하는 것으로 용사가 일어나게 된다.The generation of the arc causes the wire to melt and at this time, the high pressure through the high pressure nozzle 18 causes the spray to spray the melt forward.

이때 와이어(12,13)는 동일금속 또는 이종 금속으로 사용할 수 있으며 이들 와이어의 용융에 따른 용사는 금속 피도체의 표면에 융착되어 합금형태를 만들게 된다.In this case, the wires 12 and 13 may be used as the same metal or dissimilar metal, and the spraying of the wires may be fused to the surface of the metal conductor to form an alloy.

아크를 이용한 용사는 주방용구와 같은 금속피도체 외에 수지물을 대상으로 할 경우 수지물에 표면 금속질감과 금속성질을 부여할 수 있다.The arc spraying agent can impart the surface metal texture and the metallic property to the resin material when the resin object is applied to the metal material other than the metal object such as kitchen utensils.

이러한 수지물 표면의 금속화를 목적으로 하는 금속용사는 기존의 크롬도금보다 간편하고 포토마스크 작업 및 에칭작업을 생략할 수 있어 유해물질 배출문제를 완전히 해결하게 되므로 환경오염을 최소화 할 수 있게 된다.Metal spraying for the purpose of metallization of the resin surface is simpler than the conventional chromium plating and can omit photomasking and etching, thereby completely eliminating the problem of toxic substance emission, thereby minimizing environmental pollution.

As described herein, the thermal spray coating apparatus 21 described above is configured to operate under the control of the controller 23 through the driver 22.

상기 용사코팅장치의 노즐부근에 위치하게될 주방용구(26)는 그 내부에 장착된 회전지그(27)에 의해 회전 가능한 상태로 배치 고정한다.Kitchen utensils 26 to be located near the nozzle of the thermal spray coating device is fixed to the rotatable state by the rotary jig 27 mounted therein.

상기 회전지그(27)는 기어드모터(24)와 결합되어 콘트롤러(23)의 제어에 따라 되고 작동하게 구성한다.The rotary jig 27 is coupled to the geared motor 24 and is configured to operate under the control of the controller 23.

콘트롤러(23)는 주방용구의 표면에 용사를 이용하여 이미지 문양 등을 음각 또는 양각 형태로 형성하거나 균질 두께의 합금층을 만드는 과정이 컴퓨터(25)내의 프로그램 제어값에 따라 실행하게 구성한다,The controller 23 is configured to perform the process of forming an image pattern or the like in an intaglio or embossed form using a thermal spray on the surface of the kitchen utensil or making an alloy layer of homogeneous thickness according to the program control value in the computer 25.

예를 들어 상기 콘트롤러(23)가 컴퓨터(25)로부터 가공대상 주방용구의 표면에 특정의 이미지 패턴을 형성하기 위한 위치제어 데이터 값을 전송받게 되면 상기 기어드모터(24)와 용사코팅장치(21)의 동작을 통제하여 컴퓨터(25)에 수록된 프로그램의 제어값 대로 주방용구의 표면에 선택적으로 용사 코팅을 실행하여 음,양각 형태의 특정 이미지나 패턴을 합금형태로 형성하게 된다.For example, when the controller 23 receives a position control data value for forming a specific image pattern from the computer 25 on the surface of the kitchen utensil to be processed, the geared motor 24 and the thermal spray coating apparatus 21 are provided. By controlling the operation of the computer 25 to selectively apply a spray coating on the surface of the kitchen utensils according to the control value of the program to form a specific image or pattern of the yin, embossed form in the alloy form.
