Abstract

1303176 Shearing CINCINNATI Inc April 1970 15393/70 Heading B3W A method of shearing sheet stock to produce rectangular parts of different sizes with minimum wastage comprises (a) arranging the parts to be cut in consecutive order as to area, (b) shearing from a sheet of stock a blank large enough to contain a multiple of the largest size of part to be cut leaving at least a first cut-off, (c) shearing the blank into said parts of largestsize, and (d) shearing as many parts of a smaller size as possible from said first cut-off. Preferably a sheet is first sheared lengthwise, along line 44, Fig. 4, and then widthwise along line 50, which produces three cut-offs, 48, 54 and 64 each of which can be cut into parts in similar fashion. A shear used to carry out the method has a blade (18) (Fig. 1, not shown), vertically reciprocable mechanically or hydraulically, an adjustable gauging stop 20 which has probes 22 for aligning one stock, a squaring arm 24 associated with a front gauging stop 28, a scrap discharge and return shoot 29 and a control assembly 110 including a display device for indicating the sheet and parts dimensions, effective gauge length and width, shoot position &c. Operation of the machine may be manual or programme controlled.
