Description
본 고안은 저항 용접용 전극 장치에 관한 것으로서, 더욱 상세하게는 전극장치의 구조를 변경하여 스포트 용접은 물론 심 용접을 할 수 있도록 한 것이다,The present invention relates to an electrode device for resistance welding, and more particularly, to change the structure of the electrode device to enable spot welding as well as seam welding,
일반적으로 저항용접 기술은 19세기 말 미국의 톰슨에 의해서 발명된 것으로 알려지고 있는데, 이방법은 저항발열에 의한 온도상승을 이용하여 재료를 용융 접합시키는 기술이다. 두 금속을 접촉시켜 그면에 수직으로 압력을 가한 후 강한 전류를 흘리면 접촉부분은 급격히 온도가 올라가 반용융상태로 되며 가해지는 기계적 압력에 의해 두 금속체는 밀착된다. 이때 전류를 끊으면 그 부분이 응고되어 용접이 완료된다.In general, resistance welding technology is known to be invented by Thomson of the United States at the end of the 19th century, this method is a technique of melt bonding the material by using the temperature rise by the heat of resistance. When two metals are brought into contact with each other and a pressure is applied perpendicularly to the surface, a strong current flows, and the contact portion rapidly rises in temperature to form a semi-melt state. At this time, if the current is cut off, the part is solidified and welding is completed.
대표적인 저항용접법으로는 스포트 용접, 심 용접, 프로젝션 용접, 업셋 용접 그리고 프레시버트 용접 등이 있다.Typical resistance welding methods include spot welding, seam welding, projection welding, upset welding and fresh butt welding.
종래의 스포트 용접은 도 1 에 도시된 바와 같이 접합하기 위한 모재(10)(10a)를 적층시킨 후 상기 적층부의 상·하부에 스포트 용접 전극(20)(20a)을 접촉시켜 모재(10)(10a)를 용접하는 것으로서, 자동차, 가전 등 주로 냉연 및 도금강판의 용접에 널리 사용되고 있으며, 빠른 용접속도 및 생산라인의 자동화가 가능하여 다른 용접 프로세스에 비해 특별한 기술없이 용접이 가능한 장점을 가지고 있다,In the conventional spot welding, as shown in FIG. 1, after stacking the base materials 10 and 10a to be joined, the spot welding electrodes 20 and 20a are brought into contact with the upper and lower portions of the laminate to form the base material 10 ( 10a), which is widely used for welding cold rolled and plated steel sheets, such as automobiles, home appliances, etc., and has the advantage that welding can be performed without special technology compared to other welding processes because of fast welding speed and automation of production line.
또한 심 용접은 도 2 에 도시된 바와 같이 모재(10)(10a) 의 적층부 상·하면에 원판형태의 전극(30)(30a)을 이용하여 가압 회전시키면서 연속적으로 스프트 용접을 반복하는 방법이다. 이러한 용접부 형태는 스포트 용접기로서, 피치를 미세하게 하여 고속타점을 행하므로서 기밀, 수밀을 얻을 수 있다.In addition, the seam welding is a method of repeating the welding welding continuously while pressing and rotating by using a disk-shaped electrode 30, 30a on the upper and lower surfaces of the base 10 (10a) as shown in FIG. to be. Such a welded form is a spot welder, which can achieve airtightness and watertight by fine pitching and high-speed strike.
뜨 심 용접시 통전간격(용접간격)을 크게한 경우에는 롤 스포트라고도 한다. 이때는 단순히 강도를 유지하는 성질을 갖게된다.It is also called a roll spot when the gap between welds is increased. In this case, the strength is simply maintained.
심 용접시의 통전은 통상 규칙적인 단순(ON-OFF)을 행하는데 이는 용접부에 적당한 열평형을 얻기 위함이다. 따라서 용접 너깃(용융부)를 생성할 정도의 전류를 통전하여 용융이 판의 표면까지 미치지 않을 정도에서 통전을 정지하고 냉각시간을 주는 방법을 반복한다.The energization during seam welding is usually carried out on a regular basis (ON-OFF) in order to obtain a proper thermal balance of the weld. Therefore, the method is repeated by supplying a current enough to generate a weld nugget (melt) to stop the energization and give a cooling time until the melting does not reach the surface of the plate.
그러나 심 용접법은 전극의 회전방향으로만 용접이 이루어지기 때문에 급작스러운 방향전환이나 반경이 작은 원 등을 용접할 경우에는 제약을 받게되며, 상기 전극이 오염되어 용접불량이 발생되는 등의 문제점이 있었다.However, the seam welding method is limited in the case of welding a sudden change of direction or a circle with a small radius because the welding is made only in the rotational direction of the electrode, there is a problem such that the electrode is contaminated and welding failure occurs. .
본 고안은 상기한 문제점을 해결하기 위해 고안한 것으로서, 전극 장치의 하부에 구형 전극을 설치하여 스포트 용접은 물론 심 용접용 전극으로 사용 할 수 있는 저항 용접용 전극 장치를 제공하는데 그 목적이 있다.The present invention is devised to solve the above problems, and has an object to provide an electrode device for resistance welding that can be used as a spot welding as well as spot welding by installing a spherical electrode in the lower portion of the electrode device.
상기 목적을 달성하기 위한 본 고안 저항 용접용 전극 장치는 모재를 용융시킨 후 이를 가압하여 용접하는 저항 용접용 전극 장치에 있어서, 상기 전극 장치의 하부에 형성된 요입홈과, 상기 요입홈의 내부에 삽입되는 구형의 전극과, 상기 요입홈에 삽입된 전극의 회전을 안내하는 다수의 볼과, 상기 요입홈의 일측에 나사결합되며 이물질 제거날이 형성된 커버로 구성 된것이다.An electrode device for resistance welding according to the present invention for achieving the above object is a resistance welding electrode device for melting a base material and then pressing the welding material, the recess groove formed in the lower portion of the electrode device, and inserted into the recess groove. It is composed of a spherical electrode, a plurality of balls for guiding the rotation of the electrode inserted into the concave groove, the screw is screwed to one side of the concave groove, the cover formed with a foreign material removal blade.
