Abstract

FIELD: mechanical engineering; plastic metal working. SUBSTANCE: apparatus includes bed 1 carrying cradle 2, pressure beam 6 used for pressing blanks 27 against cradle 2, movable carriage 10 with driving shaping rolls for folding edges of sheet blanks 27, and sheet edge detent for retaining these prior to folding. Cradle 2 has longitudinal groove 3 for folding edges of sheet blanks 27 and enabling shaping rolls to pass along during performance of folding operation. Load-bearing surfaces 4 and 5 of pressure beam 6 are parallel to load-bearing surfaces 7 and 8 of cradle 2. Sheet edge detent is made in the form of strip movable in plane parallel to bed 1 in direction perpendicular to longitudinal axis of cradle 2 and deriving its drive fastened to bed 1. Advance of carriage 10 enables shaping rolls whose axes are disposed at different angles relative to longitudinal axis of pressure beam 6 to start folding edges of sheet blanks 27. EFFECT: greater capacity and reduced inter-operation time required for orienting shaping rolls. 11 dwg
