BENDING-AND-STRAIGHTENING MACHINE TOOL Russian patent published in 1998 - IPC

FIELD: plastic metal working, in particular, bending and straightening of sheets and sections. SUBSTANCE: machine tool has undercarriage for machine tool motion relative to its base, bed in the form of two frames, cross-pieces located between frames and carrying deforming members. One of deforming members located on the upper cross-piece mounted for reciprocation along cross-piece and reciprocation in vertical plane in direction to lower cross-piece. Motion in vertical plane in direction to lower cross-piece is effected from power drive ensuring smooth regulation of motion value. Cross-pieces are made with cantilevers. Machine tool has also supporting grips one of which is installed stationary, while the other is installed for reciprocation. EFFECT: higher efficiency. 3 cl, 2 dwg
