APPARATUS FOR CUTTING TUBES Russian patent published in 2000 - IPC

FIELD: machine engineering, namely plastic metal working, possibly tube cutting equipment. SUBSTANCE: apparatus has cutting head with mechanism for radially moving sliders 2. Said mechanism is in the form of disc springs 4 and two symmetrically arranged axial-action hydraulic cylinders 5. Springs 4 are preliminarily loaded and arranged in sliders 2. Rods 6 of hydraulic cylinders 5 are kinematically joined with sliders 2. At working stroke of rods 6 disc springs 4 transmit motion of sliders with cutting discs 3 and cutting effort. Reverse stroke of sliders is realized only due to rod motion. EFFECT: improved design of mechanism for radially moving sliders of apparatus for cutting tubes, enhanced reliability and simplified structure of cutting head. 2 dwg
