STAND OF SHAPE BENDING MILL Russian patent published in 2005 - IPC

FIELD: plastic working of metals.

SUBSTANCE: stand includes housing, shaping aggregate. The last is in the form of two rigidly and mutually joined jaws in which two horizontal shafts-inserts are mounted. On said shafts-inserts shaping rollers joined with drive mechanism are rigidly mounted one over another with possibility of changing inter-axial distance. Shaping aggregate is in the form of stand module whose jaws consist of dismounted frameworks. Horizontal shafts-inserts with shaping rollers are mounted in movable carriages with possibility of their vertical motion. Shaping rollers are mounted in bearing assemblies of movable carriages and they are joined by key joint with said horizontal shafts-inserts. In order to provide possibility for changing inter-axial distance, horizontal shafts-inserts with shaping rollers are mounted in movable carriages whose vertical motion is timed with use of kinematic circuit and adjusted by means of two lead screws. Each of said screw has thread portions with mutually opposite direction of thread. Stand module is arranged on platform mounted in foundation with possibility of inclination in vertical plane by angle up to 30є due to its motion in annular grooves of foundation by means of worm pair. The last includes segment rigidly joined with platform; worm engaged with said segment.

EFFECT: enlarged manufacturing possibilities and increased module quantity of construction.
