Abstract

1390022 Controlling shearing machines WILKINS & MITCHELL Ltd 10 Feb 1972 [9 Feb 1971] 4299/71 Heading B3W A steel billet of usable quality throughout its length and to be cut into pieces 18-25 of equal length d with one off cut 26 of random length is fed by first means (not shown) against a back stop 10 positioned at a distance d from the shear plane 13, clamped by hold down 14, 15 and sheared by blades 11, 12 successively until a photo-cell 30 detects that the remaining uncut portion is between nd and (n+1) d, n, as shown, being equal to 1. This first shearing cycle is immediately stopped and second cycle starts in which second feed means, a retractable pusher 17 reciprocable along a member 16, is actuated to feed the portion 25, 26 towards the stop 10 until its trailing edge 29 is at a distance nd from the shear plane 13. The off cut 26 is sheared off and the piece 25 is ejected by the next billet. If n=more than 1, i.e. the uncut portion when the photo-cell 30 stops the shearing cycle contains two or more lengths d plus the off cut 26, after the off cut has been sheared, pieces of length d are sheared from the remaining portion as were the lengths 18-24. After each shearing operation in which the stop 10 is involved, the stop is retracted to allow the sheared piece to be discharged. The position of the backstop may be adjusted automatically in dependence on the weight per unit length of the billet which is signalled to the backstop from weighing apparatus.
