The device for parting rails by combined cut of the present invention has a frame (1) with a rail (6) clamping mechanism (2) arranged therein, cutting units (3, 4), each with independent drive, and a drilling and milling unit (5) with a drive. Cutting disk (31) of the lower cutting unit (3) is positioned perpendicular to the longitudinal vertical plane of the rail (6), while the cutting disk (41) of the upper cutting unit (4) is angularly adjustable relative to the longitudinal vertical plane of the rail (6), After finish of the rail (6) parting, both the cutting disks (31, 41) reach with a gap between their peripheral parts adjoining each other, into a central opening (68) performed in a rail (6) web (63) in the cut region. The drilling and milling unit (5) with a drive is mounted on the frame (1) in slidable manner in the direction parallel to the clamped rail (6). In addition to the central opening (68), openings (64) for bolts of connecting clips are performed in the rail (6) web (63) for connection of the rail (6) parts (6A, 6B). Sharp edge of the cut on the rail (6) side leading for the wheel tire is ground to chamfer (67). |
