<p>The sheet is used for cutting of metal parts of rod-type shape of any cross section, for example, round (solid and tube-like), rectangular, square and profile (angular, T-, H- and U-shaped, and others) rod steel material. The sheet has higher bucking strength and reliability. It is formed in a plane like a flat housing with holes, the form of which is made of a straight line (1) getting across the tip of the teeth, a second straight line (2) found under angle theta towards straight line (1) so that the width of the sheet (Bi) grows linearly in a direction opposite to the direction of cutting the sheet. Two arc-like sections (3) of different lengths and two holes (4) for fitting the sheet to the sawing machine are positioned in such a way so that the straight line (5) on which their axes lie should be parallel to the straight line (1) lying at a distance (E) in the direction opposite to the side of the teeth towards a straight line (6) getting at some distance equal to half of the minimum width of the sheet Bmin/2 towards the straight line (1). Sizes theta and E alternate depending on the sprocket (chain) inequalities 0.8 ( tg theta ( and 0.4 ( E ( 0.8 where E means percent (%) of the distance measured between the centres of holes (4). 2 claims, 1 figure</p> |
