Abstract
A material shearing apparatus uses a horizontal receiver bar in support of a pair of spaced apart vertical guide rods having retainer blocks fixed in place on them, and a shearing head slidingly engaged with the guide rods so as to move between raised and lowered positions. A camshaft rotates eccentrically in the retainer blocks so as to bear on the shearing head which is thereby moved downwardly against return springs.
Claims9
A material shearing apparatus comprising:
- a rectangular bed adapted for resting on a surface, the bed having a front, left, right and rear sides, and a horizontally oriented top plate, the top plate extensive between the sides;
- and mounted to the bed along the rear side, a shearing assembly including:
- a) a horizontal receiver bar;
- b) a pair of spaced apart vertical guide rods fixed respectively to the receiver bar and extending upwardly therefrom;
- c) a pair of retainer blocks fixed respectively at upper positions on the guide rods;
- d) a shearing head slidingly engaged with the guide rods, the shearing head movable between raised and lowered positions on the guide rods;
- and
- e) a camshaft rotatable eccentrically in the retainer blocks, the camshaft bearing on the shearing head, the head thereby moveable downwardly against a pair of return springs engaged respectively with the guide rods, thereby driving a blade in the shearing head to sever a workpiece lying in contact with the top plate and extending between the blade and the receiver bar.
