MILL FOR MAKING DIFFERENT-FLANGE BENT CHANNEL SECTIONS Russian patent published in 1995 - IPC

Abstract RU 2040993 C1

FIELD: metal pressure forming. SUBSTANCE: mill has successively arranged forming stands with upper and lower working rolls. The rolls include cylinder- cone members with different diameters. All lower rolls have two members, their small diameter member has two lateral working surfaces, symmetrical relative to its medial line. Inclination angles of generatrices of large-diameter members in each of first three stands are equal to inclination angles of generatrices of the small-diameter members. EFFECT: lowered labor consumption upon making different-flange channel sections with the same high quality of these sections. 1 cl, 2 dwg
