OTO and Abbey mill forming technologies from Fives cater to a wide range of process requirements:
• Small to very large outside diameters: 4 mm – 762 mm
• A wide range of thicknesses: 0.5 – 30 mm
• ERW, laser welding and TIG
The forming section can be delivered with conventional solutions including two rolls stands or semi universal solutions, such as cage forming and TBS, or fully universal solutions. Fives offers many different technologies for changeover and completely automated, software-controlled roll adjustments.
This configuration offers the best control on the tube tolerances and optimum power distribution along the line. It makes conventional forming particularly suitable for greater thicknesses, square and rectangular tubes.
The proper cage forming section follows, consisting of two lateral beams on which assembled rolls form the tube. The system management software ables to calculate recipes and working positions.
Transition Beam System
It minimizes tooling cost and reduces size changeover times. Setups can be easily stored and recalled thanks to a software system that carries out the automatic rolls position adjustments.
It enables you to achieve high precision thanks to the combination of driven breakdown passes and an idle transition section. Roll adjustments are carried out automatically to guarantee the best repeatability.
