High-tech for tube, bars and wire straightening

VIOLI Srl specialises in the design and production of industrial machinery dedicated to the manufacturing of tubes and wires, typically used in the processes of drawing, winding, straightening and cutting. Founded in 1992, Violi Srl offers a range of comprehensive and reliable straightening machines able to process cold and hot metal profiles. The full line includes equipment for straightening tubes or bars made of steel or other metals having a circular, cross or complex profile. The MRT Series for tubes and bars is equipped with straightening groups consisting of hyperbolic pairs of rollers obliquely mounted and having an inclination opposed to each pair. The orientation of the axes, combined with the hyperbolic geometry of the rollers, allows the profile to rotate forwards. All the rollers are mounted on motorised and independent supports flowing within bushings that allow the operator to modify the height and the angle of the system. Acting on the vertical axis, it is possible to adapt the straightening machine to different diameters and to correct the line of the advancement of the profile in order to create a process of metal stressing and to get products perfectly straight. Two motors with inverter and switch to reverse the direction of the motion allow the operator to control and adjust the speed of advancement of the profiles under process. The MRT line includes three models with different capacities: BSA Tube Runner Ltd, a UK-based tube and pipe bevelling equipment manufacturer, has announced the introduction of two new pneumatic tube prepping machines: the BSA Thunderbolt and the BSA Lightning. These rugged, high powered machines can face, internal bevel, external bevel and weld remove on a wide range of materials including stainless steel and other exotic alloys. The Thunderbolt is designed to machine tube and pipe work from 12.5mm to 89mm outside diameter. The Lightning extends this range up to 115mm. Drawing on its vast experience in the production of tube bevelling equipment

MRP60D straightening machine for complex profiles

MRT5 for tubes and bars with diameter from 3 to 11mm; MRT5M for tubes and bars with diameter from 10 to 30mm; and MRT5M50 for tubes and bars with diameter from 25 to 50mm. The range of Violi straightening machines is completed by the MRP Series, a family of products for square or rectangular profiles to process hot or cold drawn bars of different thicknesses and widths. The devices consist of motorised rollers adjustable in height, with decimal display system. Acting on the vertical axis, it is possible to correct the line of the advancement of the profile in order to get perfectly straight products. Simply replacing the traction rollers makes it possible to process almost all profiles included in the working range. Violi Srl – Italy Fax: +39 0575 815903 BSA Tube Runner has engineered these machines to offer several improvements over their previous equivalents. Completely new pneumatic motors are smaller and lighter without sacrificing power or torque and have the added benefit of being quieter in operation. The machines are fitted with a hand wheel feed mechanism, which allows the skilled operator to ‘balance’ his cut to obtain the best possible finish in the minimum time.
