IMPROVEMENT IN CNC MACHINE FOR PIPELINES METAL CUTTING

摘要

Summary: comprising a rotary coupling (2) the end of the working duct consisting of a duct retention device (3) associated with a rotating wheel with rack (4) driven by a motor (5) providing rotation of said duct. The cut metal working duct is accomplished by a cutting tool (6) arranged on the tailstock (7) on a mobile gantry (8) and moved transversely motor spindle (9). Where the porch (8) is mounted on a rail (10) in a base (11) and is still mounted one second gantry (12) additional support for the pipeline. Both the mobile gantry (8) as the gantry (12) are equipped with a central opening (13) for the passage of the duct equipped with self-centering frame (14) which automatically holds the duct. The cutting tool (6) is attached to the movable gantry (8) for quick coupling, comprising a magnetic plate (17) at the base of the cutting tool (6) associated with the magnetic plates (18) fixed to the gantry (8) , one in the front face (19) and the other on the rear face (20), so that the cutting tool (6) can be moved from the front face (19) to the rear face (20).
