Roundo R1 to R6 bending machines

with spiralfing device Type
The models of ROUNDO  R1 to R6 section bending machines are basic machines with a strong and rigid design. The three bending shafts are journalled in heavy SKF bearings. The top roll is equipped with a slip clutch, compensating for the difference in speed of the inner and outer diameters of the section being bend. Mechanically operated guide rolls, Standard Rolls which facilitate bending of non symmetrical sections, especially angles, are standard equipment. worm gear motor drives all three rolls irrespective Angle leg out. The guide rolls of adjustment position. 

All three rolls are driven irrespective of adjustment position. Is driven by a worm gear motor equipped with magnetic brake. Models and are driven by hydraulic motors, providing infinitely variable rotation speed.

STANDARD EQUIPMENT
Compensating and adjustable slip clutch for the top roll.
Set of standard rolls combined for standard angle leg out and leg in, flat bar on flat and on edge, T, small round bar and square bar.
Complete guide roll assemblies which automatically follow the operation of the hydraulically operated lower rolls, including leg in attachment.
Dial indicators showing the position of the lower rolls.
Hydraulic adjustment of the two lower rolls.
SKF bearings in all journals.
Emergency stop button.
Roll adjustment by hand levers and portable push button control for roll rotation.
Portable push button control for all functions.
SPECIAL ROLLS
Rolls for pipe. Each set of rolls can be designed for one or two different sizes of pipe.
Rolls for round bar.
Rolls for square and rectangular tubing.
Combined rolls for I and U beams the easy way, adjustable for all different sizes covering the capacity of the machine.
Rolls for high production of rings by spiral bending of flat bar, pipe and other profiles.
Rolls for special sections and profiles are designed on request. In some cases the rolls are made of nylon to avoid marking and tearing on easily damaged sections.

OPTIONAL EQUIPMENT
Combined Horizontal Vertical design.
Hydraulic infinitely variable drive on all three rolls.
lnfinitely variable drive via frequency changer.
Portable push button control for all functions.
Digital display showing the positions of the lower rolls.
Microhydraulic adjustment of the lower rolls.
Pushing roll unit for improved bending of thin sectional and angle bars.
Special guide unit for bending I and U beams the hard way.
Spiral bending device for pipes and flat bar.
Half pipe equipment to form and bend a half pipe from a flat strip.
Wide seIection of special rolls.

Capacities and Specifications Type ROUNDO
Wide range of Special Section Bending machines
4 Roll section bending machines type to
ROUNDO also supplies a range of section bending machines with four rolls.
In the 4 Roll section bending machine the sections are pinched between top and lower roll, which are also the driven rolls. This offers the possiblity for prebending with extremely short remaining straight ends.
Perfect machine for vehicle chasis components that requires three dimensional bending.
Machine with hydraulic guide rolls offers total flexibility.
Models available with section modulus capacity 10 500 cm

The world's most powerful section bending machine
Model is designed mainly to bend solid profiles. The capacity of this machine makes it possible to bend flat bar mm the hard way, or square bar mm, both in steel with yield point. Each lower roll can apply a force of up to 1000 Tons.

Beam Bending Machines
This range of machines is specially developed for heavy beam bending, aiming for the highest possible demands of production speed, quality and capacity. With features
like adjustable bending distance and simultaneous movement of pushing and pulling roll, the versatility of these machines is unique. The different ROUNDO models cover up to 15 000 cm section modulus and up to 1100 mm beams over X X axis.

4 Roll Plate Bending Machines
The standard range of 4 roll plate bending machines covers plate thicknesses of 3 100 mm and widths of 1000 8000 mm.

3 Roll Plate Bending Machines
Three Roll Double Pinch plate bending machines.
Available in lengths up to 8000 mm and thickness to 100 mm.

Quick Rolling Machines
Plate bending machines for large production runs of cylinders with cycle times as short as 10 seconds. For plate thicknesses up to 12 mm and widths up to about 2000 mm.

Flanging and Punching Machines For flanging and punching cylinders in the same operation. Cylinder diameters of 350 3000 mm and plate thicknesses up to 8 mm.

Plate straightening Machines straighten plates with thicknesses of 2 40 mm and widths up to 4000 mm. Produced with 5, 7 or 9 rolls depending on tolerance requirement.
