LINE FOR MAKING LATTICED SHAPE Russian patent published in 2004 - IPC

FIELD: realization of inner, outer, heat insulation and spackling works in building while using perforated shapes.

SUBSTANCE: line includes arranged according to manufacturing process order: blank uncoiler; multi-stand shape-bending mill and shearing apparatus. Working stands of multi-stand shape bending mill are mounted in framework and they have common drive unit, lower stationary housings, upper movable housings in which drive shafts with working disc type tools are mounted. First working stand includes discs for forming in blank lengthwise central groove. Discs of second working stand are cutting discs and they are designed for forming notches. Discs of third working stand are in the form of cylinders with straight-line generatrix. Discs of next stands are toothed ones and they are designed for stretching out notches. Number of working stands of mill for stretching notches is equal to that of pairs of notch rows symmetrical relative to lengthwise symmetry axis of blank. Discs of working stands for stretching out notches are designed for forming cross section of latticed shape. Shearing apparatus of line may operate without interruption of motion of ready shape.

EFFECT: enlarged manufacturing possibilities, enhanced efficiency.
