Abstract
1,204,638. Making hollow ware; flanging. J..P. CALCATERRA, J. V. MINIACI, T. A. MoCOY, D. J. CALCATERRA, G. Q. RHINEFRANK, F. D. MUSTO and D. P. BISBEE. 21 May, 1969 [24 Jan., 1969], No. 25978/69. Headings B3A and B3Q. A die-unit for forming an outwardly turned flange on a cylindrical sheet-metal body 5, Fig. 3, e.g. in making a drum or pail, comprises two semi-circular die halves 20, Fig. 2, fixed on a support 2 with a gap 12 therebetween, each half 20 having a flanging trough 22 with an outer stop-wall for the flange provided by a semi-circular band 24 anchored at its ends and yieldable outwardly at a number of separate locations along its length. Except for being in two halves, to provide the gap 12 for feed fingers 7, the die, band 24 and the method of making the drum or pail are substantially the same as those described in Specification 1,195,827, to which reference is made. Blanks 5 are fed along a table 4 and above the die by a chain conveyer 8 carrying the fingers 7, the upper run of the chain being beneath the support 2 while its lower run passes through a hollow frame 6, 11 which guides posts 3 for raising the die and a blank to form a flange when the blank is located beneath an abutment (not shown). Slots 14 in the die-halves and stop-segments 25 receive rails 15 along which the blanks are fed and which eject flanged workpieces, the rails having a pin-and-slot 18, 19 connection with the support 2. Operation.-A blank 5 is fed above the die which is in its low position, Fig. 3, and the parts are timed so that the die is immediately raised to form a flange beneath which the feed fingers 7 may pass. The die is now lowered so that the rails 15 eject the flanged workpiece, which is removed by a feed finger 7.
