FIELD: machine engineering, namely forming on flat sheet blanks such as foil or thin-sheet blank portions with angular orientation. ^ SUBSTANCE: machine tool includes cross beam engaging with press for fixing portion of sheet blank subjected to bending. Said cross beam has apron jointly secured to it by means of hinge. One art of said hinge is formed by means of casing having cross section in the form of cylinder section extended by nose limiting together with cylinder sector opening of casing. The last is designed for placing in it by sliding other part of hinge. Said other part is in the form of conchoid-shaped curl having cross section in the form of cylinder section also extended by holding nose. ^ EFFECT: improved design of machine due to using hinge joining cross beam with apron that may be easily mounted and dismounted or made as one piece. ^ 5 cl, 8 dwg |
