ABSTRACT:
An automatic shear angle adjusting apparatus for a shearing machine comprising a first cylinder having a piston and piston rod unit mounted therein, the piston rod of the first cylinder being fixedly secured to the left end upper surface of an upper cutter, and a second cylinder having a piston and piston rod unit mounted therein, the piston rod of the second cylinder being fixedly secured to the right end upper surface of the upper cutter. A solenoid-operated valve is disposed in a conduit connecting a source of pressurized fluid with a rod end chamber of the first cylinder and a head end chamber of the second cylinder. A detector is arranged for detecting angular deflection of the upper cutter from a predetermined shear angle. Responsive to the detector is a control circuit which actuates the solenoid-operated valve either to connect the rod end chamber of the first cylinder and the head end chamber of the second cylinder to the source of pressurized fluid or to a drainage whereby shear angle is automatically adjusted and kept within a predetermined optimum shear angle.
