METHOD OF PRODUCTION OF TRAPEZOID SECTIONS Russian patent published in 1997 - IPC

Abstract RU 2092255 C1

FIELD: methods of production of high-precision slip-ring sections including those of small cross-section. SUBSTANCE: method includes assembly of combined blank from strips round in cross-section with high accuracy in axial fixing of combined blank in process of its deformation in common rhombic pass to exclude notches and scores of surface of deformed rough slip-ring sections, increased accuracy in formation of geometric sizes of their cross-section, reduced consumption of guide fitting and labor input on fitting of combined blank into common rhombic pass and mastering production of high-precision slip-slop sections with sectional area less 10 sq.mm. EFFECT: higher quality of high-precision slip-ring sections, cut down cost and extended technological potentialities in production of precision trapezoid sections having one axis of symmetry. 3 dwg
