Description
본 발명은 헤밍실러의 미립화 산화철 비드에 관한 것으로서, 기존의 글래스 비드 또는 세라믹 비드를 배제하고, 대신에 자동차의 조립 라인에서의 스폿 용접시에 생성되는 미립화 산화철을 비드로 하여 헤밍실러에 첨가함으로써, 원재료비를 절감할 수 있으며, 기존의 비드보다 더 우수한 성질을 갖는 헤밍실러의 미립화 산화철 비드에 관한 것이다.The present invention relates to an atomized iron oxide bead of a hemming sealer, by eliminating existing glass beads or ceramic beads, and instead of adding the atomized iron oxide produced during spot welding in an automobile assembly line as a bead to the hemming sealer, Raw material costs can be reduced, and the present invention relates to atomizing iron oxide beads of hemming sealer having better properties than conventional beads.
일반적으로, 자동차의 구성 부분을 크게 나누면 섀시와 보디로 나눌수 있다.In general, the car's components can be divided into two parts: the chassis and the body.
상기 보디는 객실과 적재함 등으로 이루어지고, 사람이나 하물을 싣는 부분이며, 자동차의 외장에 해당하는 것이다.The body is made of a cabin and a loading box, and is a part for carrying a person or baggage, and corresponds to an exterior of a vehicle.
상기 섀시는 자동차에서 보디 부분을 제외한 것을 말하며, 자동차의 골격에 해당하는 섀시 프레임에 엔진등, 주행하는 데 필요한 장치 일체를 장치한 것으로 섀시만으로도 주행할 수 있다.The chassis refers to a vehicle excluding a body part, and the chassis frame corresponding to the skeleton of the vehicle is provided with all the devices necessary for traveling, such as an engine, and can be driven only by the chassis.
상기 보디에는 도어, 본넷, 트렁크 리드 등이 장착되는 바, 이들은 프레스 가공에 의해 제작된다.The body is equipped with a door, a bonnet, a trunk lid and the like, which are produced by press working.
상기 프레스 가공은 레버, 나사, 수압 등을 이용하여 금형등에 재료를 가압하여 일정한 모양으로 성형하며, 재료내에 전단응력을 발생하여 재료를 목적의 형상으로 성형하는 전단가공, 인발, 전단 등에 의하여 얻은 재료를 목적의 모양으로 굽히는 굽힘 가공, 재료를 원주방향으로 압축함과 동시에 반경 방향으로 연신하여 목적의 형상으로 성형하는 드로잉 가공, 상하형이 상호 대응되는 형을 갖는 엠보싱 가공, 상하형이 관계 없는 요철을 각인하는 압입 가공 등이 있다.The press work is a material obtained by shearing, drawing, shearing, etc. by pressing a material into a mold or the like using a lever, a screw, a hydraulic pressure, etc., and forming a predetermined shape by generating a shear stress in the material. Bending to bend to the desired shape, drawing processing to compress the material in the circumferential direction and draw in the desired shape by drawing in the radial direction, embossing process with the upper and lower molds corresponding to each other, irregularities regardless of the upper and lower molds Press-fitting and the like.
프레스 가공 기계에는 수동식과 동력식이 있으며, 수동식은 비교적 형이 작고 간단한 제품을 박판으로 제작할 때 사용하고, 동력식은 크랭크 기구에 의하여 플라이 휠이 가지고 있는 회전 운동에너지의 일부를 1 회 사용하고 잔여의 에너지로 펀치를 상승시키는 프레스로서, 단동식(single action type)과 복동식(double action type)이 있다.There are two types of press processing machines, manual and motorized. Manual type is used to make relatively small and simple products in thin plates. Power type uses one part of the rotational kinetic energy of the flywheel by the crank mechanism. As a press for raising the furnace punch, there are a single action type and a double action type.
한편, 자동차에서의 패널은 일체로 프레스된 외판이나 내판을 말한다.On the other hand, a panel in an automobile refers to an outer plate or an inner plate that is integrally pressed.
즉, 아우터패널이라든가 인너패널 또는 리어 엔드패널이라고 부른다.That is, it is called an outer panel, an inner panel, or a rear end panel.
예를 들면, 도어패널의 인너패널(100)과 아우터패널(200)은 통상 자동화된 조립라인 중에서 자동적이면서도 연속적으로 헤밍작업과 점용접에 의해 결합되어 패널의 기본뼈대를 형성하는데, 도어패널의 선단부를 보면, 아우터패널(200)이 뒤집어 꺾은 상태를 유지하게 되는 바, 이와 같은 것을 헤밍(hemming)이라 하며, 모서리 부위를 헤밍 플랜지라고 한다.For example, the inner panel 100 and the outer panel 200 of the door panel are usually combined automatically and continuously by hemming and spot welding in an automated assembly line to form a basic skeleton of the panel. As shown, the outer panel 200 is kept upside down to be folded, this is called hemming (hemming), the corner portion is called a hemming flange.
즉, 평탄한 패널에 헤밍을 만드는 것을 헤밍 가공이라고 하며, 여기에 쓰이는 공구 및 프레스를 헤밍 툴 및 헤밍 프레스라고 한다.That is, making a hemming on a flat panel is called a hemming process, and the tool and press used here are called a hemming tool and a hemming press.
도 2에 도시된 바와 같이, 헤밍 공정을 거친 패널의 선단부, 즉 인너패널(100)과 아우터패널(200) 사이에는 방청과 강도를 향상시킬 수 있도록 헤밍시일을 하게 되는 바, 헤밍실러(300)를 헤밍부위에 도포한 후, 헤밍부위에 유도가열원을 공급하여 경화시키고, 점용접을 통해 상기 패널(100, 200)을 결합시킨다.As shown in FIG. 2, a hemming seal is provided between the front end portion of the panel, that is, the inner panel 100 and the outer panel 200, to improve rust prevention and strength, as shown in FIG. 2. After the coating on the hemming site, the induction heating source is supplied to the hemming site and cured, and the panels 100 and 200 are bonded through spot welding.
이때, 헤밍부의 접착력 강화를 위해 사용되는 헤밍실러(300)의 접착력, 즉 전단 강도를 보강하기 위해 상기 헤밍실러(300) 내에 글래스(glass)나 세라믹 등의 재료로 된 비드(400)를 첨가한다.At this time, a bead 400 made of a material such as glass or ceramic is added to the hemming sealer 300 to reinforce the adhesive strength, that is, the shear strength, of the hemming sealer 300 used to strengthen the adhesive force of the hemming part. .
헤밍후, 상기 비드(400)가 패널(100, 200)에 박혀 전단력이 상기 패널(100, 200)에 가해졌을때 전단력에 저항하여 부착력을 증가시킨다.After hemming, the bead 400 is embedded in the panels 100 and 200 to increase the adhesion by resisting the shear force when the shear force is applied to the panels 100 and 200.
그런데, 종래의 헤밍실러중에 글래스 비드는 가격이 비싸고, 전단 강도에 대해 약하며, 특히 내충격성에 약하다.By the way, among the conventional hemming sealers, glass beads are expensive, weak in shear strength, and particularly weak in impact resistance.
세라믹 비드는 가격이 저렴한 반면에 상기 비드의 상이 구형, 타원형, 또는 선형으로 되어 있어 패널 전단력에 대한 저항치가 균일하지 않을 수 있는 문제점이 있다.While ceramic beads are inexpensive, the beads may be spherical, elliptical, or linear, resulting in a non-uniform resistance to panel shear force.
따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 기존의 비드를 배제하고, 대신에 자동차의 조립라인에서 수거할 수 있는 미립화 산화철을 헤밍실러의 비드로 이용함으로써, 용이하게 재활용할 수 있어 재료비를 절감할 수 있고, 기존의 비드보다 효과면에서도 우수한 성질을 갖는 헤밍실러의 미립화 산화철 비드를 제공하는데 그 안출의 목적이 있다.Therefore, the present invention has been made in view of the above problems, and by removing the existing beads, instead of using the atomized iron oxide that can be collected in the assembly line of the vehicle as a bead of the hemming sealer, it can be easily recycled. The purpose of the present invention is to provide an atomized iron oxide bead of a hemming sealer which can reduce material costs and has superior properties in terms of effectiveness than conventional beads.

이하, 본 발명의 특징에 대해 설명하면 다음과 같다.Hereinafter, the features of the present invention will be described.
인너 패널(100)과 아우터패널(200) 사이에 방청과 강도를 향상시킬 수 있도록 실링하는 비드(400)를 함유한 헤밍실러(300)에 있어서, 상기 비드(300)의 재료가 스폿 용접시에 생성되는 미립화 산화철(10)인 것을 특징으로 한다.In the hemming sealer 300 containing the bead 400 which seals between the inner panel 100 and the outer panel 200 to improve the rust prevention and strength, the material of the bead 300 is spot welded. It is characterized in that the atomized iron oxide (10) produced.
이하, 첨부도면을 참조하여 본 발명의 구성에 대해 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.
본 발명은 헤밍실러(300)내 함유되는 비드(400)의 성분으로서, 미립화 산화철(10)을 이용하고자 한다.The present invention intends to use the atomized iron oxide 10 as a component of the bead 400 contained in the hemming sealer 300.
상기 미립화 산화철(10)은 철이 용융점 이상의 온도에서 산화된 후 급속 냉각된 조직으로서, 도 1에 도시된 바와 같이, 자동차의 조립 라인상에서의 스폿 용접시에 생기는 불꽃에서 흔히 관찰된다.The atomized iron oxide 10 is a structure that is rapidly cooled after iron is oxidized at a temperature above the melting point, as shown in FIG. 1, which is commonly observed in sparks generated during spot welding on an assembly line of an automobile.
상기 미립화 산화철(10)의 형상은 거의 완전한 구형으로 형상의 균일화가 우수하다.The shape of the atomized iron oxide 10 is almost perfect spherical shape is excellent in uniformity of the shape.
또한, 표면 성분은 산화철이고 내부성분, 또한 철과 산화철이 혼합되어 있는 상태로서 비교적 안정한 물질이다.In addition, the surface component is iron oxide, and the internal component is a relatively stable substance in which iron and iron oxide are mixed.
한편, 도어 패널의 헤밍시에 흔(dent)을 형성하며 패널에 박힐 수 있는 경도를 갖고, 충격 강도에 의한 저항성이 높아 방청과 강도를 향상시킬 수 있다.On the other hand, when hemming the door panel, a dent is formed and has a hardness that can be embedded in the panel, and resistance to impact strength is high, so that rust prevention and strength can be improved.
이상에서와 같이 본 발명에 따른 헤밍실러의 미립화 산화철 비드는 자동차의 조립라인에서 이용되는 스폿 용접에 의해 생성되는 흔한 물질로서 쉽게 재활용할 수 있고, 헤밍실러내 함유시, 충격 강도에 대한 저항성이 높아 방청과 강도를 향상시킬 수 있는 효과가 있다.As described above, the atomized iron oxide bead of the hemming sealer according to the present invention can be easily recycled as a common material produced by spot welding used in the assembly line of an automobile, and when contained in the hemming sealer, has high resistance to impact strength It has the effect of improving rust prevention and strength.
