STRIP EDGE PREPARATION UNITS
These devices have been designed and manufactured in order to meet the quality requirements of the lines with LASER welding system and in any case to ensure optimum quality of the strip edges if it was specifically required also in other applications.
There are two systems:

  • Device with tools: it works by means of three opposite tools and is pneumatically and hydraulically adjustable and controlled.
  • Device with rolls: this system relies on a series of orientable rolls in contact with the material and adjustable according to the strip width.

NEW BEAD GRINDER WITH FLAP WHEELS
A considerable increase of the use of laser welding has solicited the development of a machine for external bead grinding, which is indicated for a different configuration of the laser welding seam and for the increased production speed. A new equipment has been engineered which, thanks to the use of special flap wheels, permits to eliminate the bead at high speeds without scratching the surface of the tube. The work is done in a completely dry condition, with considerable reduction of maintenance times and costs. Furthermore, the device for the automatic wearing compensation allows to obtain a completely homogeneous removal.

NEW MAGNETIC BEAD ROLLER
This equipment, specifically designed for laser welding Tube Mill, gives the advantage of no mechanical connections between mandrel and any external support: the wire rope moving the mandrel in the traditional hydraulic system can be totally eliminated.
The internal mandrel works thanks to the magnetic field generated by a permanent magnet sliding on rails in an alternate rectilinear motion. This permits also the consequent reduction of the minimum inside-rolling diameter.

NEW FLYING SHEAR CUT OFF
Tube cutting is operated by means of two tools which are hydraulically operated and controlled by the latest electronical technologies.

The whole process is controlled by one hydraulic cylinder which guarantees the perfect synchronization of the cutting cycle and to obtain optimum conditions on the cutting time. In addition the employ of hydraulic systems assures an easy use of the machine and a reduction of maintenance times and costs, compared to the use of mechanical systems.
The movements of the cutting carriage are electronically controlled to guarantee the automatic adaptability to the tube speed.
Moreover an inclination system allows the automatic tool centring on the tube angle in case of production of square and rectangular profiles.
This equipment is offered in two different models covering ranges from 15 to 76 mm O.D. and from 30 to 114 mm O.D., with wall thicknesses from 0.8 mm to 3.5 mm.
