ABSTRACT:
A shearing machine is provided. The machine comprises a lower stationary jaw detachably mounted on one end of an arm of a working machine for rotatable and tiltable movement, the lower stationary jaw having attached thereto a plurality of shearing blades, an upper movable jaw having a plurality of shearing blades adapted to be opened and closed in a scissors-like manner relative to the shearing blades of the lower stationary jaw so as to shear an article to be sheared, and a hydraulic cylinder for pivotally moving the upper movable jaw. The forward-end shearing blade of the lower stationary jaw and the forward-end shearing blade of the upper movable jaw are arranged in a staggered or angled manner relative to their respective adjacent shearing blades of the lower and upper jaws, respectively, so that the forward-end shearing blades of the lower and upper jaws, respectively, may be first engaged with each other, when moved in a vertical direction.
