Abstract

PURPOSE:To hold the blank securely on the table, by holding down the blank fed on the table in a manner to block the blank processing holes penetrating the rotating table vertically through, by means of the blank holding mechanism at its outer edge part. CONSTITUTION:A rotating table 2 holds a blank 57 cut to a specified size, and, while intermittently rotating in the direction of arrow (d), successively feeds it from feed position H of forming press position I, burr-blauking press position J and outside diameter blanking take-out position K. Eight blank processing holes 60 at equal intervals, and a blank holding mechanism 61 free to open and close with respect to each hole 60 are provided on the circumference of the table 2. The mechanism 61 is supported in a manner movable vertically with respect to the table 2, at a position inward in the radial direction of the table 2 from each hole 60, and a rod being pushed up 87 is linked to each mechanism 61 outward in the radial direction of the table 2 by means of pivot pin. By projecting each rod 87 in a manner slidable vertically beneath the table 2, a device to push up the rod 87 when the table 2 stops is elevatable provided, beneath the table 2, corresponding to the position H and outside diameter blanking take-out position K.
