<p>Hydraulic sheet-metal shearing machine comprising a movable apron pivotally mounted about an eccentric axis of rotation of adjustable angular position permitting of modifying at will the initial clearance between the blades. The support of the sheet abutment device is hingedly mounted to the movable apron about an axis shifted in relation to the pivotal axis thereof, and which has likewise an eccentric position. The shafts materializing these two axes are operatively interconnected through means capable of correcting the position of said abutment device when the clearance between the blades is modified by pivoting the eccentric hinge shaft of said movable apron.</p> |
