Abstract
PURPOSE: To prevent the position deviations of steel plates with themselves during transferring to the next process, in continuous blanking of the steel plates of the same shape from a long-sized steel plate, by forming a plurality of projections holding the adjacent steel plates in the predetermined positions of the steel plates and piercing holes engaging the projections at every predetermined sheet number.
CONSTITUTION: In continuously blanking products 11 of the same shape from a long-sized steel plate 14, an elevatable upper die 1 provided with a jig 3 and a punch 5 and a stationary lower die 2 provided with a product take-out port 4 are used, and a plurality of projections 15 of the same shape as that of the jig 3 are formed in the predetermined positions of the blanked products 11 by the notched parts of the jig 3 to hold the next products 11. Further, holes 17 engaging said projections 15 are pierced in the positions opposing to said projections at every predetermined number. The piercing of said holes 17 is accomplished at every predetermined sheet number by means of the projections 6 of the punch 5 and the recesses 7 of the lower die fitting thereto, with the aid of the function of a punch push-down rod 13 etc. In this way, the products may be lumped by every desired sheet number and the position deviations during transferring is eliminated.
