SHAPE BENDING MACHINE Russian patent published in 1995 - IPC

FIELD: metal treatment by pressure. SUBSTANCE: shape bending machine to produce thin-walled shapes, made from flat sheet billets by restricted bending has placed in manufacturing sequence driven forming stands (for preliminary and final shaping ) with rollers pairs, that have closed shaping clearance, and apparatus for dressing. In the case stand for preliminary shaping, that is capable of movement in vertical and horizontal planes, is provided with overtaking coupling. Apparatus for dressing is capable for rectilinear longitudinal movement. Value of minimum distance between forming stands is given by definite dependance (see original). Dimensions of shape bending machine are significantly less, than dimensions of other known machines, therefore machine has decreased metal consumption. Machine requires less power and production space. Cost of shapes, produced by machine, is low and quality - high. EFFECT: shape bending machine is used in metal treatment by pressure. 2 dwg
