SHAPING MILL Russian patent published in 2004 - IPC

FIELD: plastic metal working, namely working sheet material by means of special profile rolls, possibly in ferrous metallurgy, machine engineering, building for making bent shapes or shaped tube blanks in aggregates for producing welded tubes or powder wire. SUBSTANCE: in base of shaping mill there are grooves normal relative to axis of shaping mill and designed for mounting housings mill stands and lids. Said housings are in the form of U-shaped pairs of jaws with outer and inner lateral guides. Shaping unit with idle rollers are provided with horizontal and (or) vertical crosspieces mounted with possibility of motion along lateral guides of jaws. Idle rollers of shaping unit are mounted in cross pieces with possibility of motion in plane of their axes. Lower horizontal rolls of stands are driven ones. In last stand upper horizontal roll may be driven one. Rotation drives of lower horizontal rolls of stands, except last one, are provided with slides mounted with possibility of axial motion and designed for joining said drives with clutches. Slides are mounted on brackets provided in casings of bearing assemblies. At least one stand has vertical crosspiece mounted in inner lateral guides of jaws and having shaping idle rollers. At shaping complex-profile articles, shaping unit with idle rollers is provided with horizontal and vertical crosspieces mounted with possibility of motion on lateral guides of jaws. On outer lateral guides of jaws of housing of terminal stands there are lateral cross pieces having guiding means with idle rollers. EFFECT: minimum size, low material and energy consumption for making and maintaining shaping mill, enhanced quality of shaped articles. 6 cl, 8 dwg
