FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming and may be used for bending elongated billets to preset radius. Proposed machine tool comprises bending rolls, two-dimension laser transducer of displacement downstream of multiple bending rolls, and computer. Computer is connected with said two-dimension laser transducer incorporating length gage to measure the length of billet bent section provided with drive. Note here that said drive may actuate of one of aforesaid bending rolls and allows adjustment of said roll proceeding from measured and preset curvature radii. ^ EFFECT: higher accuracy of bending. ^ 3 cl, 1 dwg |
