FIELD: instrumentation engineering. SUBSTANCE: parallel shears with the upper cut for cutting the fashioned U-shaped profiles has movable upper knife 1 and immovable lower knife 2. Their cutting edges are parallel to the plate perpendicular to the cut plane. Their rakes are equal to zero. The cutting edge of lower knife 2 is identical to the contour of the cross-section of profile 3 to be cut. The cutting angle of movable upper knife 1 is made equal to 90. The ratio of the side rake angle of lower knife 2 to its cutting angle makes up 0.06-0.20. EFFECT: facilitated manufacture. 3 dwg
