PLATE CATALYST CUTTING METHOD

PURPOSE:To make a cutting line square with a center line of a blanking as well as to aim at improvement in a rate of cutting yield, by setting a cutting position to a sectional circular arc with the center line of a forming line, in case of a cutting process after continuous forming of a bent steel strip-formed product. CONSTITUTION:A circular rail 8 is laid down in the lower part of a cutting body 11 with a cutting blade 3, and a stopper 9 for stopping movement of the cutter 11 is installed in the rail 8. And, when a plate catalyst 4 is fed to the cutting blade 3 from a press die 2, the cutter 11 is arcedly moved in both directions by the stopper 8 and the rail 8 after being adjusted to a bending direction of the plate catalyst 4. With this constitution, a position of the cutting blade 3 is sectorally moved to a center line of the plate catalyst 4 and comes into orthogonality to the center line of the plate catalyst 4. Therefore, the proper form plate catalyst 4 is cut and manufacturable all the time, through large bending at the time of molding this catalyst 4 has occurred.
