METHOD OF PRODUCTION OF OPEN SLENDER SECTION BY MEANS OF BENDING

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to metalforming and can be used for manufacturing of cold-bent profiles made of strip. Continuously sequentially it is implemented strip bending in the raw of rolling contour gage with constant tension. Roller for creating of bottom sections of each following gage allows increased rolling diameter. Additionally mentioned roller of each rolling contour gage is implemented as driving. ^ EFFECT: it is increased profiles dimensional accuracy. ^ 2 cl, 1 ex
