Method and apparatus for forming sharp styling lines on metal panels |
摘要 |
An apparatus and method for forming a style line with a sharp radius in a metal with lower formability than that of mild steel is disclosed. The apparatus and method use a die set with a means to back a portion of the metal having the style line formed with a material that moves with the surface of the style line as it is formed. In one embodiment an elastic member backs the metal panel, and in another embodiment a fluid medium backs the metal panel where the style line is formed. The apparatus and method achieve sharper radius style lines in metals like aluminum, advanced high strength steel, and ultra-high strength steel than a traditional hard surface die set can achieve. |
