Abstract
PURPOSE: To smoothly produce many blanks of a fixed shape without forming edge burrs and edge warp by joining the ends of a first lateral blade and a longitudinal blade at a fixed angle between the blades.
CONSTITUTION: A longitudinal blade 5 of a lower die is aligned with the center line of a sheet steel 1. A first lateral blade 6 is joined with the longitudinal blade 5 at one end forming a fixed angle (90°). The first lateral blade 6 extends in the left half of the sheet steel 1 with respect to the center line X. The edge of a second lateral blade 7 is longitudinally separated from the first lateral blade and located in the right half of the sheet steel 1 with respect to the center line X. The length and location of the cutting blades are defined as: F≥C≥A, D≥B and E≥B, where A is the length of blanks, B is the width of blanks, C is the length of the blade 5, D is the length of the blade 6 and E is the length of the blade 7.
