Method of making an earth tilling sweep from disc scrap |
摘要 |
<p>A method of making earth tilling sweeps from disc scrap including a process of cutting a plurality of circular discs side-by-side to form disc cut-outs as well as discs. Each cut-out is formed around an axis which is perpendicular to the plane of the sheet of metal from which the discs are cut. The method herein includes leaving a predetermined width of material between the disc cut-outs and a predetermined width of metal between each respective disc cut-outs on at least one of the side edges. A sweep blank is made by cutting between and through the width of metal between the cut-outs and between the one edge and each one of two adjacent cut-outs. Further cutting of the sweep blank toward its final configuration includes forming attachment openings therein. The sweep blank is then bent into a three-dimensional shape for use in tilling the earth.</p> |
