<p>PROBLEM TO BE SOLVED: To provide a shearing edge of a thick steel plate shearing machine providing a fine shearing plane.SOLUTION: A shearing edge of a thick steel plate shearing machine shears plate width direction side surface of a thick steel plate for a thick steel plate longer direction. The shearing edge is a rectangular solid shape, and a point edge part of the rectangular solid contacting with a thick steel plate shearing plane at a tip of a thick steel plate conveying direction is cut in a range of 10-300 mm to the longer direction of the thick steel plate, 10-20 mm to the width direction of the thick steel plate, and 10-100 mm to a thickness direction of the thick steel plate.</p> |
