DEVICE FOR CUTTING OF PIPES Russian patent published in 2009 - IPC B23D21/00 

FIELD: technological processes.

SUBSTANCE: invention is related to the field of metal plastic working and may be used in continuous pipe welding and profile-bending machines for cutting of moving rolled metal into specific cut lengths. Device for pipes cutting comprises frame, body installed in it with driving spindle, two hingedly fixed double-arm levers and slider joined to hydraulic cylinder. Slider is installed on guide fixed in spindle. Spindle rotation is carried out from drive. At every end of every double-arm lever there is head fixed with driving saw blade, every of which has rotation drive from electric motor. Other ends of double-arm levers are connected to slider by means of traction rods with spherical heads that interact with spherical step-bearings installed at the ends of these levers. Traction rods with spherical heads may be arranged as both solid and length-adjusted. Controlled rods are made of two parts joined to each other by means of nut.

EFFECT: provision of pipes and different profile billet cutting into specific cut lengths.
