APPARATUS FOR CORRUGATING TUBES Russian patent published in 2003 - IPC

Abstract RU 2205715 C2

FIELD: manufacture of corrugated tubes, mainly with helical corrugations. SUBSTANCE: apparatus includes housing; mounted on housing mechanisms for radial motion, rotation and fixing angle of shaping discs and drive units for their radial motion in the form of power cylinders. Apparatus is provided with system for syncronizing radial movements of shaping discs. Said systems includes rigidly joined one with another syncronizing cylinders with rigidly joined pistons; drive unit of cylinders; sets of distributing apparatuses and pipelines for each power cylinder providing at least seven variants of switching working and return cavities of power cylinders, cavities of syncronizing cylinders, of pressure and draining main pipelines. Liquid is used as working fluid of power and syncronizing cylinders. Drive unit for moving piston of syncronizing cylinders is in the form of hydraulic cylinder. Number of power cylinders is equal to that of syncronizing cylinders. Set of distributing apparatuses for each power cylinder includes at least three two-way distributors; one distributor is two-position and two other distributors are three-position ones. Working cavity of each power cylinder is provided with pressure regulator. EFFECT: enhanced quality of corrugated tubes, enlarged manufacturing possibilities, high reliability of apparatus. 8 cl, 7 dwg
