METHOD FOR MANUFACTURING GUIDE FOR GLASS LIFTER Russian patent published in 2006 - IPC B21D5/00 B21D11/20 B21D35/00 

FIELD: process for manufacturing of flexible guide for glass lifter used in automobile construction industry.

SUBSTANCE: method involves bending flat blank for creating of U-shaped cross-sectional profile having bottom and vertical walls with bent horizontal strip; providing radial bending thereof. Bending of flat blank is carried out by means of punch in die for thinning of vertical walls in outer cross section by means of skew portions provided on die, said bending process being carried out simultaneously with radial bending and die stamping of slot on horizontal strip on the side of die. Method allows vertical walls to be created, which have thickness of cross-sectional profile equal to nominal thickness of material of flat blank and thickness at the bottom equal to 0.87 the nominal thickness of material of flat blank.

EFFECT: increased efficiency in bending of cross sectional profile, providing transverse stretching of material simultaneously with radial bending in stamp die of simplified construction and on stamping press of simplified operation.
