Abstract
Description
본 발명은 휴대형 탈자 장치에 관한 것으로서, 보다 상세하게는 용접기 또는 자동 용접기의 전원에 의해 발생하는 전류를 이용하여 철판 등의 원하는 부위로 이동시켜 탈자시키는 휴대형 탈자 장치에 관한 것이다.The present invention relates to a portable demagnetization device, and more particularly, to a portable demagnetization device that moves to a desired part, such as an iron plate, using a current generated by the power of a welding machine or an automatic welding machine to demagnetize.
일반적으로, 강재를 제조하는 과정이나 운반, 보관, 가공, 비파괴검사, 용접 등의 과정에서 강한 자기적 쇼크를 받거나 장시간 자기적 분위기 하에 적치될 때 상기 강재에서 자화가 유발된다. 특히, Fe-Ni 합금강은 일반 탄소강에 비하여 쉽게 자화되는 특성이 있다. 이에 따라 금형가공, 프레스가공, 용접 등의 2차 가공 작업시에는 세심한 주의를 하지 않으면 자화 현상이 필연적으로 발생한다. 만약, 이렇게 자화된 강재를 사용할 경우, 자화된 강재의 주변에 산재(散在)된 이물질, 예컨대 금속성 물질이나, 분진 등이 자착되어 제품 생산에 악영향을 끼치고, 또한, 압연롤과 같은 경우 압연되는 제품이 자화된 롤에 자착되는 등의 여러 가지 문제점이 발생하게 된다. 이에 따라, 자화된 강재는 탈자(脫磁)를 시켜주어야 한다.In general, magnetization is induced in the steel material when subjected to strong magnetic shock in the process of manufacturing the steel material or during transport, storage, processing, non-destructive inspection, welding, etc., or when placed under a magnetic atmosphere for a long time. In particular, Fe-Ni alloy steel has a property of being easily magnetized as compared to general carbon steel. Accordingly, in secondary processing such as mold processing, press processing, and welding, magnetization occurs inevitably without careful attention. If the magnetized steel is used in this way, foreign substances scattered around the magnetized steel, such as metallic materials or dust, adhere to itself and adversely affect the production of the product. Various problems, such as being attached to the magnetized roll, occur. Accordingly, the magnetized steel must be stripped.
그러나, 종래의 탈자장치는 탈자 대상물이 중량물이나 특정 장비에 부착되어 있는 경우에는 탈자를 하기 어려운 문제점이 있다.However, the conventional demagnetization device has a problem that it is difficult to demagnetize when the demagnetization object is attached to a heavy object or specific equipment.
본 발명은 상기 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 용접기 또는 자동 용접기의 전원에 의해 발생하는 전류를 이용하고 철판 등의 원하는 부위로 이동시켜 탈자시키는 휴대형 탈자 장치를 제공하는 것이다.The present invention has been devised to solve the above problems, and an object of the present invention is to provide a portable demagnetization device that uses a current generated by a power source of a welding machine or an automatic welding machine and moves to a desired portion such as an iron plate to demagnetize.
상기 목적을 달성하기 위해, 본 발명에 따른 휴대형 탈자 장치는 일측은 용접기의 전원공급부와 접속하고 타측은 부하부와 접속하여 상기 용접기의 전원공급부와 부하부를 전기적으로 연결함으로써, 상기 용접기의 전원공급부와 부하부 사이에 흐르는 전류를 이용하여 탈자하는 탈자수단을 포함하는 것을 특징으로 한다.In order to achieve the above object, the portable stripping apparatus according to the present invention is connected to the power supply of the welding machine by connecting one side to the power supply of the welding machine and the other side to connect to the power supply of the welding machine and the load portion, thereby electrically connecting the power supply of the welding machine. It characterized in that it comprises a demagnetization means to demagnetize using the current flowing between the load.
본 발명에 의하면, 용접기 또는 자동 용접기의 전원을 통해 발생하는 전류를 이용하는 탈자수단을 철판 또는 강재의 원하는 부위로 이동시켜 탈자시킬 수 있음으로써, 용접 현장 등 작업 현장에서 강재 또는 철판 등의 원하는 부위를 용이하게 탈자시킬 수 있다. According to the present invention, by moving the demagnetization means using a current generated through the power of the welding machine or the automatic welding machine to a desired portion of the steel plate or steel, it can be demagnetized, so that the desired site, such as steel or iron plate, in the work site such as a welding site. It can be easily stripped.
도 1은 본 발명의 구성을 개략적으로 나타내는 도면이다.1 is a view schematically showing the configuration of the present invention.
본 발명은 용접기 또는 자동 용접기의 전원 공급부(power supply)의 전원을 부하부에 연결하여 발생하는 전류를 탈자수단에 이용함으로써 철판 또는 강재의 원하는 부위를 탈자시키는 것이다.The present invention is to demagnetize a desired portion of a steel plate or steel by using a current generated by connecting a power source of a power supply of a welding machine or an automatic welding machine to a load portion in a demagnetizing means.
다시 말해, 고정 설치되는 용접기의 전원 공급부와 탈자수단의 일측 접속 단자를 케이블을 통해 연결하고, 탈자수단의 타측 접속 단자는 부하부와 케이블을 통해 연결하여 용접기의 전원 공급부와 부하부를 전기적으로 연결시켜 전류를 발생시키고, 발생되는 전류에 의해 탈자수단에서 전자기력이 발생됨으로써, 이를 이용하여 상기 탈자수단을 철판 또는 강재의 원하는 부위에 접근시켜 탈자 작업을 하는 구조이다.In other words, the power supply of the welding machine to be fixed is fixed, and one connection terminal of the stripping means is connected via a cable, and the other connection terminal of the stripping means is connected via a load and a cable to electrically connect the power supply and load of the welding machine. It is a structure that generates electric current and generates electromagnetic force in the demagnetizing means by the generated current, thereby using the demagnetizing means to approach the desired part of the steel plate or steel to perform demagnetization work.
