Sheet Metal Forming 판재 성형 Mass Production Sheet Metal Forming 판재 성형 10

Sheet metal forming (판재성형) Sheet metal forming is a processes that shape a piece of sheet metal into the desired part through shearing(전단) and deformation(성형). It is also called pressworking, press forming, or stamping. Sheet metal can be cut, bent, and stretched into a nearly any shape. Material removal processes can create holes and cutouts in any 2D geometric shape. Deformation processes can bend the sheet numerous times to different angles or stretch the sheet to create complex contours. Sheet metal fabrication processes can mostly be placed into two categories - forming and cutting. Forming processes are those in which the applied force causes the material to plastically deform, but not to fail. Such processes are able to bend or stretch the sheet into the desired shape. Cutting processes are those in which the applied force causes the material to fail and separate, allowing the material to be cut or removed. Most cutting processes are performed by applying a great enough shearing force to separate the material, and are therefore sometimes referred to as shearing processes. Other cutting processes remove material by using heat or abrasion, instead of shearing forces.

Automotive Stamp Die (프레스 금형) Process: Drawing → Trimming → Hemming → Punching 자동차의 차체 패널은 드로잉(drawing), 트리밍(trimming), 헤밍(hemming), 펀칭(punching) 등 통상 3~4단계의 프레스 공정을 거쳐서 만들어진다. 트림 다이, 피어스다이 중간공정 또는 최종 프레스 공정에서 제품을 필요형상으로 만들기 위하여 전체 둘레 또는 부분 적으로 스크랩(scrap))부분을 절단하는 가공 틀을 트림 다이(trim die)라 하고 가공재료에 구멍을 뚫는 금형을 피어스 다이(pierce die)라고 한다. 피어싱 가공은 상형다이에 펀치 리테이너 (retainer)와 피어스 펀치 (pierce punch)를 설치하고 하형 다이에 버턴다이(button die)를 설치 하여 가공재료에 구멍을 뚫는 작업이며, 뽑힌 부분이 스크랩이 되고 뚫린 구멍이 제품 역할을 하게 된다. 프레스 기계에 의한 피어싱에 있어서는 동시에 여러 개의 구멍을 뚫을 수 있지만 여기에는 제작 조건도 따른다. 이러한 가공들은 가공면이 기울어졌거나 형상에 따라서는 옆에서 절단해야 할 경우에는 고도의 기술을 필요로 하는 전단(shear)가공의 하나이다. http://www.youtube.com/watch?v=ydoEJnwMlnk

Roll forming Roll forming: Metal strip is bent as it pass through series of rolls. Roll bending: Cylindrical shaped produced from plate. Roll forming, sometimes spelled rollforming, is a metal forming process in which sheet metal is progressively shaped through a series of bending operations. The process is performed on a roll forming line in which the sheet metal stock is fed through a series of roll stations. Each station has a roller, referred to as a roller die, positioned on both sides of the sheet. The shape and size of the roller die may be unique to that station, or several identical roller dies may be used in different positions. The roller dies may be above and below the sheet, along the sides, at an angle, etc. As the sheet is forced through the roller dies in each roll station, it plastically deforms and bends. Each roll station performs one stage in the complete bending of the sheet to form the desired part. The roller dies are lubricated to reduce friction between the die and the sheet, thus reducing the tool wear. Also, lubricant can allow for a higher production rate, which will also depend on the material thickness, number of roll stations, and radius of each bend. The roll forming line can also include other sheet metal fabrication operations before or after the roll forming, such as punching or shearing.
