METHOD OF MAKING STRIP RECTANGULAR HIGH-ACCURACY SHAPES Russian patent published in 1996 - IPC

Abstract RU 2062671 C1

FIELD: rolled stock production, namely, production of high-accuracy strip profiled blanks in specialized shops of machine engineering plants. SUBSTANCE: method comprises formation of cross section of octahedral blanks while taking into account normalized values of angle α between adjacent inclined faces and width of flat portion of bases D, D1. Such normalization allows to receive due to combination of assembling octahedral blanks to builtup blank and repetitive rolling of builtup blank in edge and four-roll non-adjustable roll grooved passes as series of experimental rolling procedures had shown two types of dimensions of shapes in the same set of rolls. Method provides production of shapes having thickness less than 1.5 mm, enhanced efficiency, decreased number of rolls being used and lowered labor consumption at making edge grooved pass. EFFECT: enlarged manufacturing possibilities, enhanced efficiency. 1 cl, 7 dwg
