SHAPE PRODUCTION METHOD Russian patent published in 2002 - IPC

FIELD: manufacture of elongated products by extrusion. SUBSTANCE: method comprises steps of extruding billet from container through die, guiding shape between adjusted rollers of stands, clamping and transporting shape by means of drawing apparatus along table of press; trimming shape, transferring it crosswise onto axle of stretching machine, stretching it, feeding it crosswise on roller table of cutting line, cutting shape by measured length values, straightening cross curvature of shape fed on table of press by realizing correction deformation of shape between adjusted rollers of stands mounted on table of press. Rollers are adjusted in horizontal and(or) in vertical planes simultaneously with process for extruding billet. EFFECT: possibility for realizing correction deformation of shape in horizontal and(or) vertical planes simultaneously with extrusion process. 14 dwg
