Beschreibung
Zusammenfassung:	The invention discloses an excess-material-free blanking process and die. The die comprises an upper die plate, a lower die plate, a first outward-turning die, a second outward-turning die, a third flattening die and a fourth cutting-off die. Due to the fact that a shell body is separated from a material belt in a side cutting mode, the defect that the four corners of the shell body turn outwards is overcome, and the size precision of a product is high. In addition, waste materials in the blanking process are all connected to the material belt, no excess waste material is generated, and a working table is tidier.
