Description

전자기 피닝장치{Electromagnetic peening device}
본 발명은, 전자기력을 통해 피가공재에 잔류압축응력을 생성되게 하는 전자기 피닝장치에 관한 것이다.
일반적으로, 피닝(Peening)은 금속 표면을 해머로 때려 표면 강도를 개선하는 기계적인 처리를 말하며, 용접의 경우에는 비드 표면을 두드려서, 응력 완화, 균열 및 변형의 방지를 목적으로 하는 표면처리 방법이다.
이러한, 피닝은 숏 피닝, 레이져 피닝 및 워터젯트 피닝 등이 사용되고 있으며, 그 중에서도 숏 피닝이 가장 널리 사용된다.
여기서, 숏 피닝(Shot peening)은 금속 재료 및 용접이음부의 표면에 숏 볼(Shot ball)이라는 강구를 고속으로 타격하여 피가공물의 외면에 압축응력이 잔류되도록 하는 표면 가공법이다. 또한, 숏 피닝 가공을 하는 품목은 매우 다양한데, 예를 들면, 여러 형상의 기어, 증기나 가스 터빈 부분, 비행기의 착륙 장치 부분, 헬리콥터 프로펠러의 구동축과 날개, 압축기와 고성능 엔진 부품이나 피스톤, 크랭크축, 커넥팅 로드 등의 첨단 기계 분야의 금속재료에 적용된다.
그러나, 숏 피닝 장치는 금속재료 표면의 충분한 강도와 세밀한 처리를 제공하지 못함으로써 정밀 부품에 부적합하며, 금속재료 표면의 손상이 발생하여 후처리가 번거롭고, 표면 강도를 균일하게 증가시키지 못하는 문제점이 있다.
또한, 숏 피닝은 사용재인 강구로 인해 인체에 피해를 주고, 공해를 유발하며, 강구를 강하게 쏘아줄 펌프 등이 필요해 장치의 규모가 크고 이동이 어려운 문제점이 있다.
이같은, 종래의 피닝 장치에 대한 관련 기술은, 대한민국등록실용신안공보 제20-0483229호(2017.04.11)에 제시된다.
본 발명은, 피가공재의 넓은 면적에 대한 표면처리가 가능하면서 표면처리 시 접촉에 의한 표면결함, 마멸, 윤활 등의 문제가 없고 반복적인 작업이 가능함과 더불어 친환경적인 표면처리를 가능하게 하는 전자기 피닝장치를 제공하는데 목적이 있다.

또한, 상기 전원공급부와 커패시터는 병렬상태로 연결 배치하며, 상기 전원공급부와 커패시터 사이에는 충전스위치를 연결 구비하고, 상기 커패시터와 코일 사이에는 방전스위치를 연결 구비할 수 있다.
또한, 상기 본체의 내주면에서 본체의 내측 중심 방향으로 갈수록 폭이 가늘어지게 연장 형성된 테이퍼 형상의 쉐이퍼부와, 상기 쉐이퍼부의 끝단으로부터 본체의 내측 중심 방향으로 동일한 폭을 가지는 상태로 연장 형성되는 응력출력단부를 포함할 수 있다.
본 발명에 따른 일 실시예에 따른 전자기 피닝장치는, 전원공급부에서 커패시터로 전류가 충전된 후, 커패시터에서 본체의 코일로 순간적으로 전류가 인가되게 하면서 자기장을 발생되게 하고, 발생된 자기장이 피가공재에 반대방향의 유도전류를 유발함에 따른 로렌츠 힘이 본체의 내측에 삽입 배치된 피가공재에 잔류압축응력이 생성되도록 표면처리되게 하는 바, 소모성 부품의 사용이 없게 되어 친환경적이며, 피가공재에 대한 표면처리를 넓은 면적에 대해 가능하게 함과 더불어 생성되는 잔류압축응력의 깊이도 조절할 수 있게 한다.
도 1은 본 발명의 일 실시예에 따른 전자기 피닝장치의 개략 구성도이다.
이하 첨부된 도면을 참조로 본 발명의 바람직한 실시예들을 상세히 설명하기로 한다.
도 1은 도 1은 본 발명의 일 실시예에 따른 전자식 피닝장치의 개략 구성도이다. 도 1을 참조하면, 일 실시예의 전자기 피닝장치는, 본체(100), 전원공급부(200), 커패시터(300)를 구비하고 있다.
상기 본체(100)는 이후 설명될 커패시터(300)로부터 전류를 전달받아 자기장을 발생함에 따라 피가공재(10)에 반대방향의 유도전류를 발생시, 야기되는 로렌츠 힘을 통해 피가공재(10)의 피닝을 이루어지게 하는 부분이다. 이러한, 본체(100)는 피가공재(10)을 외측에 감싼 상태로 삽입 배치되게 할 수 있도록 원형의 단면을 가지면서 양단이 개방된 관 구조를 가진다.
그리고, 상기 본체(100)의 외주면에는 커패시터(300)로부터 전류를 전달받아 자기장을 발생시키는 코일(110)을 감김상태로 설치한다. 이같이, 상기 본체(100) 상에서의 코일(110) 감김수 및 본체(100) 외측에서의 코일(110) 감김길이에 따라 피가공재(10)에 대한 잔류압축응력의 깊이 및 면적을 조절할 수 있게 된다.
또한, 상기 본체(100)의 내주면에는 코일(110)에서 발생되는 자기장을 통한 피가공재(10) 표면으로의 로렌츠 힘이 균일하게 집중 전달되면서 피가공재(10)에 균일한 응력분포의 잔류압축응력이 생성되는 표면처리가 이루어지게 하는 응력가압부(120)가 형성된다. 이러한, 응력가압부(120)는 본체(100)의 내주면에서 본체(100)의 내측 중심방향으로 돌출되게 형성되며, 쉐이퍼부(121), 응력출력단부(122)를 포함한다. 이때, 응력가압부(120)는 피가공재(10)를 기준으로 양측에 대향되게 배치하도록 한 쌍이 형성된 것으로 도시하였으나, 이에 한정하지 않음은 물론이다. 여기서, 쉐이퍼부(121)는 자기장을 통해 발생되는 로렌츠 힘을 본체(100)의 내주면에서 피가공재(10) 방향으로 세기를 크게할 수 있도록 본체(100)의 내주면에서 본체(100)의 내측 중심 방향으로 갈수록 폭이 점점 가늘어지도록 테이퍼 형상으로 연장 형성된 부분이다. 응력출력단부(122)는 쉐이퍼부(121)로부터 전달받은 로렌츠 힘을 피가공재(10)에 균일하게 전달되게 할 수 있도록 쉐이퍼부(121)의 내측 끝단으로부터 본체(100)의 내측 중심방향으로 동일한 폭을 가지도록 연장된 부분이다.
상기 전원공급부(200)는 본체(100)의 코일(110)로 전류를 공급하는 부분이다. 이러한, 전원공급부(200)는 본체(100)의 코일(110)과 메인케이블(210)을 통해 연결한다. 여기서, 전원공급부(200)는 직류와 교류 및 펄스를 선택적으로 적용 가능할 수 있으며, 주파수와 폭 및 세기를 조절할 수 있음은 물론이다.
상기 커패시터(300)는 전원공급부(200)로부터 전류를 전달받아 설정된 범위의 전압상태까지 전류를 충전한 후 코일(110)로 전달되게 하는 부분이다. 이러한, 커패시터(300)는 코일(110)을 통해 발생되는 자기장의 세기를 증폭되게 한다. 여기서, 커패시터(300)는 전원공급부(200)와 병렬상태로 코일(110)과 전기공급부(200) 사이에 연결 배치되도록 병렬케이블(220)에 연결 설치한다.
여기서, 상기 전원공급부(200)를 코일(110)과 연결되게 하는 메인케이블(210)에는 충전스위치(400) 및 방전스위치(500)를 연결 구비할 수 있다. 이러한, 충전스위치(400)와 방전스위치(500)는 전원공급부(200)에서 공급되는 전류를 커패시터(300)에 충전된 후, 커패시터(300)에 충전된 전류가 코일(110)로 순차적으로 전달되게 한다. 이때, 충전스위치(400)는 전원공급부(200)와 커패시터(300) 사이에 위치하도록 메인케이블(210)에 연결 배치하고, 방전스위치(500)는 커패시터(300)와 코일(110) 사이에 위치하도록 메인케이블(210)에 연결 배치한다.
더불어, 일 실시예에 따른 전자기 피닝장치에는, 전원공급부(200)의 동작 여부와 충전스위치(400) 및 방전스위치(500)의 온(ON)/오프(OFF) 동작을 제어하는 제어부(도면미도시)를 구비할 수 있다. 이러한, 제어부는 전원공급부(200)와 충전스위치(400) 및 방전스위치(500)와 연결되도록 설치한다. 따라서, 제어부에 따른 코일(110)로의 전류공급방법을 살펴보면, 최초 전원공급부(200)의 동작에 따른 전류가 커패시터(300)로 설정된 범위의 전압상태로 충전될 수 있도록 충전스위치(400)는 온(ON)상태로 유지되게 하고, 방전스위치(500)는 오프(OFF)상태로 유지되게 한다. 이후, 커패시터(300)에 설정된 범위의 전압상태로 전류가 충전완료되면, 충전스위치(400)는 오프(OFF)상태로 유지되게 하고, 방전스위치(500)는 온(ON)상태로 유지되게 하면서 커패시터(300)의 전류가 코일(110)에 인가되게 한다.
이와 같이, 일 실시예에 따른 전자기 피닝장치는, 전원공급부(200)에서 커패시터(300)로 전류가 충전된 후, 커패시터(300)에서 본체(100)의 코일(110)로 순간적으로 전류가 인가되게 하면서 자기장을 발생되게 하고, 발생된 자기장이 피가공재(10)에 반대방향의 유도전류를 유발함에 따른 로렌츠 힘이 본체(100)의 내측에 삽입 배치된 피가공재(10)에 잔류압축응력이 생성되도록 표면처리되게 하는 바, 소모성 부품의 사용이 없게 되어 친환경적이며, 피가공재(10)에 대한 표면처리를 넓은 면적에 대해 가능하게 함과 더불어 생성되는 잔류압축응력의 깊이도 조절할 수 있게 한다.
