METHOD OF MAKING HIGH-ACCURACY MANIFOLD SECTIONS Russian patent published in 1997 - IPC

Abstract RU 2088350 C1

FIELD: plastic metal working, namely production of high-accuracy trapezoidal manifold sections with one symmetry axis of ferrous and non-ferrous metals. SUBSTANCE: method comprises steps of rough and finish shaping. Rough shaping is performed by deforming pairs of initial strips in common rhombic roll grooved pass to rough manifold sections. Finish shaping is performed in common edge closed grooved pass. Composite blank for finish rolling is assembled by abutting rough sections along their large lateral faces with single side arrangement of bases. EFFECT: enhanced efficiency. 2 dwg
