Claims
- 1. A shearing machine comprising:
- a mounting bracket mounted to the end of a work vehicle arm;
- a supporting frame;
- means connected between the mounting bracket and the frame for allowing the frame to swivel relative to the bracket;
- upper and lower angled jaws connected to the frame by respective pivots;
- a lining plate attached to an inner side surface of a front recess of said lower angled jaw for slidingly contacting a front side portion of the upper jaw thereby guiding the upper jaw into the recess;
- a plurality of arcuate patching plates flush mounted within outer surfaces of the upper and lower jaws, confronting the supporting frame;
- a plurality of adjusting pins mounted to the supporting frame contacting corresponding patching plates for adjusting lateral play between the upper and lower jaws:
- each jaw portion between transversely aligned patching plates being solid;
- hydraulic means connected to at least one of the jaws for moving the jaws into and out of engagement; and
- means connected between the mounting bracket and the frame for biasing the supporting frame relative to the mounting bracket for preventing swivel rotation therebetween until a twist force, exceeding a predetermined value, is exerted on the supporting frame.
- 2. The machine set forth in claim 1 further comprising a synchronizing pin located equally distant from the pivots and connecting the upper and lower jaws for synchronizing movement of the jaws.
- 3. A shearing machine comprising:
- a mounting bracket mounted to the end of a work vehicle arm:
- a supporting frame;
- means connected between the mounting bracket and the frame for allowing the frame to swivel relative to the bracket;
- upper and lower angled jaws connected to the frame by respective pivots;
- a lining plate attached to an inner side surface of a front end recess of said lower angled jaw for slidingly contacting a front side portion of the upper jaw thereby guiding the upper jaw into the recess;
- a plurality of arcuate patching plates flush mounted within outer surfaces of the upper and lower jaws confronting the supporting frame;
- a plurality of adjusting pins mounted to the supporting frame contacting corresponding patching plates for adjusting lateral play between the upper and lower jaws;
- each jaw portion between transversely aligned patching plates being solid;
- hydraulic means connected to at least one of the jaws for moving the jaws into and out of engagement; and
- means for controlling swivel rotation of the support frame relative to the bracket for presetting the angle of the jaws relative to a workpiece to be sheared.
- 4. The machine set forth in claim 3 further comprising a synchronizing pin located equally distant from the pivots and connecting the upper and lower jaws for synchronizing movement of the jaws.
