Abstract

1367154 Shearing PROMECAM SISSONLEHMANN 9 Nov 1971 [13 Nov 1970] 52028/71 Heading B3W An hydraulic shear comprises a blade holder 8 pivotable about an axis A adjustable by means of an eccentric to adjust the cutting clearence between blade 6 and fixed blade 5, a gauging stop 21 being supported by rails 22 which are pivoted on an eccentric on the blade holder 8, the eccentric being operatively interconnected by means capable of correcting the position of the gauging stop when the blade clearance is modified by angular adjustment of the eccentric associated with the blade holder 8. At axis A a shaft 16 is mounted in eccentrics (15) (Fig. 2, not shown) angularly adjustable by means of integral levers 18 and the rails 22 are mounted on eccentrics 24 freely rotatable on pins 23 carried by the blade holder 8. The eccentrics 15 and 24 are operatively interconnected by means, such as a toothed pinion 25 on each eccentric 15 meshing with a toothed segment 27 on an eccentric 24, or vice versa, able to correct the position of the gauging stop when the cutting clearance is adjusted. The journals 15 are held in their adjusted position by engagement of pins 19 on levers 18 with a selected one of a series of holes in a fixed plate 20 on the shear frame. The correction applied by the gearing 25, 27 may keep the position of the gauging stop constant or move it forward or back in a predetermined ratio to the adjustment in cutting clearance. A further gear may be interposed between pinion 25 and segment 27. The movable blade, which may be the upper one, is actuated by cylinders 12.
