METHOD FOR MAKING GUIDE OF WINDOW RAISER Russian patent published in 2003 - IPC

FIELD: automobile making industry, namely techniques for making guides of window raiser by bending. SUBSTANCE: method comprises steps of bending = -shaped section and flange by angle equal to 80 degrees relative to vertical line; then bending =-shaped section with vertical webs and flange by angle equal to 90 degrees relative to vertical line and finally radially bending them; performing bending of flange by 80 degrees relative to vertical line by stretching it along punch; realizing bending of flange by 90 degrees relative to vertical line after rotating blank by 180 degrees. EFFECT: shortened cycle of manufacturing guides of window raiser. 4 dwg, 1 ex
