FIELD: plastic metal working, possibly manufacture of elongated tubular shells with small diameter of steel and titanium sheets. SUBSTANCE: roll type bending machine, mainly for winding elongated tubular small-diameter shells from sheet includes upper cross piece mounted in housing and supporting upper roll driven by means of hydraulic motor; table with elastic coating mounted with possibility of motion by means of hydraulic cylinder on rotating rolls mounted in cross pieces. Machine also includes apparatus for synchronizing motion of table with rotation of upper roll in the form of flow splitter, two controlled gate valves mutually connecting hydraulic cylinder and hydraulic motor, and flowrate controller placed at outlet of hydraulic cylinder or hydraulic motor. EFFECT: enhanced quality of parts, increased time period between repairing works. 3 dwg |
