<p>Device for laser cutting of draw pipes (4) comprising: a supporting bed (2) having guides (18) and a worm screw moving system (19); a saddle (1), sliding on guides along a first axis, coupled to the worm screw; a rotating system around a second axis, parallel to the first axis, comprising two concentric rings (5, 6), an external ring (5) integral to saddle (1) and an internal ring (6) free to rotate inside the external ring; a focusing head (8) for a laser beam, fixed to a support (20) on said internal ring (6), having a first degree of freedom along the focusing axis of the laser beam and a second degree of freedom that permits it to rotate and maintain the laser beam always perpendicular to the surface of the pipe to be cut. <IMAGE></p> |
