Abstract
The present invention discloses a method of motor vehicle sheet blanking and a system of the same, wherein the blanking method comprises: firstly, nesting for motor vehicle sheet material, and cutting it into group sheets with a shape and size confirmed by the multi length of the sheet; next, designing a backing die depending on scraps to be cut from the group sheet, and hollowing in areas corresponding to blanking openings in the backing die, in which the dimensions of the blanking openings are greater than that of the actual scraps to be cut; then, placing a group sheet onto the backing die; laser cutting the group sheet based on the shape of motor vehicle sheet, the cut scraps dropping through the blanking openings in the backing die onto a scrap conveyor belt underneath; stacking the cut sheets. The present invention can effectively process scraps cut from sheets and improve the blanking efficiency.
