Abstract

PURPOSE: A press manufacturing method of a vehicle panel component is provided to produce panel components with the cross sections having a fixed shape through a press process without using a roll foaming machine. CONSTITUTION: A panel is cut in the desired shape of a product through a blanking process. One end of a panel half-finished product cut by the blanking process is bent into the form of the cross section having a fixed shape. The panel half-finished product is consecutively bent into the form of the cross section having a fixed shape. The panel half-finished product bent into the form of the cross section of the fixed shape is formed into the panel half-finished product with the imperfect cross section. Finally, a panel finished product with the complete cross section is made.

자동차 패널부품 프레스 제조방법{THE PRESS PRODUCT METHOD OF CAR PANEL PART}Manufacturing method of automobile panel parts press {TH PRESS PRODUCT METHOD OF CAR PANEL PART}

본 발명은 자동차의 차체에 조립되는 패널부품을 소성가공을 통하여 성형하는 자동차 프레스 제조방법에 관한 것으로 더욱 상세히 설명하면, 자동차의 차체를 형성하는 각종 패널부품들 중 동일한 단면들로 연결된 성형라인을 갖는 패널부품을 생산하기 위하여 구성되는 자동차 패널부품 프레스 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an automobile press for molding a panel component assembled to a vehicle body through plastic processing. In detail, the present invention has a molding line connected to the same cross-section among various panel components forming a vehicle body. The present invention relates to a method for manufacturing automotive panel part presses configured to produce panel parts.

자동차의 몸체에 해당되는 차체는 강판을 소성 변형시켜 성형한 제품인 패널부품들을 조립하여 형성되며, 패널부품들을 원하는 형상이나 크기로 성형하여 제품화하는 방법에는 프레스 가공과 롤포밍 가공 등이 있다. 프레스가공은 프레스금형을 이용하여 강판인 패널을 소성가공하여 원하는 형상으로 성형시키는 가공법이며, 롤포밍은 회전하는 롤 사이로 패널을 통과시켜 원하는 형상으로 성형시키는 가공법이다. The vehicle body corresponding to the body of the vehicle is formed by assembling panel parts, which are products formed by plastically deforming a steel plate, and the method of forming the panel parts into a desired shape or size into products includes press processing and roll forming processing. Press processing is a processing method for plasticizing a panel, which is a steel sheet, using a press mold to form a desired shape, and roll forming is a processing method for forming a desired shape by passing the panel between rotating rolls.

프레스가공은 전단가공, 벤딩가공, 드로잉가공 등으로 구분할 수 있으며, 전단가공은 원자재인 강판을 원하는 형상으로 절단하는 가공으로 블랭킹, 피어싱, 세퍼레이팅, 트리밍 등이 있다. 또한 벤딩가공은 강판을 원하는 형상으로 굽히거나 비틀림 변형을 주는 가공으로 벤딩, 컬링, 트위스팅 등이 있으며, 특히 벤딩가공은 V형과 Ｕ형 및 Ｌ형 굽힘으로 세분화할 수 있다. 그리고 드로잉가공은 강판을 소성변형 구간 내에서 컵과 같은 형상으로 성형하는 가공으로 딥드로잉, 탑드로잉 등이 있다. Press processing can be classified into shear processing, bending processing, drawing processing, and the like. Shear processing is a process of cutting a steel sheet, which is a raw material, into a desired shape, and includes blanking, piercing, separating, and trimming. In addition, bending is a process of bending a steel sheet to a desired shape or giving a torsional deformation, such as bending, curling, and twisting, and in particular, bending may be subdivided into V-type, X-type, and L-type bending. In addition, drawing processing is a process of forming a steel plate into a cup-like shape in a plastic deformation section, and there are deep drawing and top drawing.
