LASER TECHNOLOGICAL COMPLEX FOR TREATMENT OF LARGE-SIZE OBJECTS Russian patent published in 2010 - IPC B23K26/08 B23K26/03 

FIELD: technological processes.

SUBSTANCE: invention relates to laser technological complex for treatment of large-size objects. Complex comprises technological laser, elements of laser radiation transportation, in the form of rotary mirrors, optical-focusing head with mechanism of its displacement along three coordinates and technological table for treated item. Technological table is arranged in the form of two platforms arranged one over another. Upper platform is arranged as movable in plane parallel to lower platform. Mechanism for billet fixation is installed on lower platform. Upper platform is arranged with the possibility to provide for rotation by 90 degrees relative to lower platform and to fix it in this position. Optical-focusing head is arranged in the form of body, in cavity of which there is a unit of fixation of spherical focusing mirror, which is placed on its wall. On opposite parallel wall there is a rotary flat mirror fixed at the distance l=F-(lnd_l/tga+2D_f._m.), where F-focus distance of spherical mirror, mm, d_l - diametre of laser beam, mm, D_f.m. - diametre of flat mirror, mm. Unit of fixation is arranged with the possibility of its rotation by 90°, displacement and fixation in horizontal direction relative to laser beam falling point at flat mirror arranged at the angle of 45°.

EFFECT: invention makes it possible to expand functionality, to increase efficiency of laser complex operation and to improve quality of billets treatment.
