ABSTRACT:
The present invention offers a steel-material shearing machine which nips steel materials after self adjusting to an optimum condition and shears all kinds of steel materials. The machine comprises: a supporting frame attached to a mounting bracket so that it can swivel freely; the mounting bracket mounted at the end of the arm of a work machine; a mechanism to hold the supporting frame to the mounting bracket by using a swivel brake mechanism until a swivel force of certain intensity is applied; a lower and upper jaws whose engaging parts are indented on their centers, and which are mounted on the supporting frame by first and second pivots respectively so that they can move freely; a synchronizing pin attached between the upper and lower jaws to operate them with equal angles; fan-shaped patching plates flush mounted on both sides of the upper and lower jaws where they make contact with the supporting frame; adjusting pins with adjustable depth attached on both sides of the supporting frame to press the patching plates; and lining plates attached on the inside of the tip of the lower jaw to guide the tip of the upper jaw.
