Roundo R4, R5, R6 bending machines

SECTION BENDING MACHINES 
All models of ROUNDO R4,R5, R6 Section Bending Machines are designed and built according to the latest technological experience in this field. Material and components have been throughly tested in all practical bending situations and with a ROUNDO Section Bending
Machine the bending operation will be carried out with a minimum of manual effort. The main frame of the machine is of all steel welded construction, heavily proportioned and welded to a structural steel base, stress relieved and then machined. All three rolls are driven irrespective of adjustment position. To protect and increase the efficiency of the machine and to avoid damages on the workpiece, the central roll is driven via a very effective and reliable slip clutch compensating for the difference between the inside and outside diameter of the bent section. Model is driven by a geared motor equipped with a magnetic brake. Models and are driven by hydraulic motors, by means of which the rotating and adjustment speeds can be varied from creep to maximum speed. The two lower rolls are individually and hydraulically operated by means of a motor driven hydraulic pump. The hydraulic unit is protected against overloading and non return valves eliminate the risk that the lower rolls change their positions during the rolling operation. The drive and method of adjustment as well as the geometry of the ROUNDO Section Bending Machines give them a unique and universal range of capacities with prebending of both leading and trailing edge without the need to remove and turn the section being bent and with a mіnіmum of losses in material.

STANDARD ROLLS
One set of combined bending rolls for flat bar on the flat and on edge, angle leg out and leg in and T bar leg out and leg in, are supplied as standard with the machines.
The rolls are hardened and located on the shafts by means of a single key, thus making it easy to adjust and change over the various special rolls that can be supplied as optional equipment. Guide rolls, partly self adjusting and necessary for bending of asymmetrical sections as well as scales indicatìng the positions of the lower rolls, are standard equipment. The machines can as an option be supplied in a combined horizontal vertical design and can easily be turned 90 to function in the vertical or the horizontal position.

STANDARD EQUIPMENT

Operators manual and service instructions.

ROUNDO Control
Model R4 with optional hydraulic pushing roll and CNC Control capable of storing 60 programs of 50 steps each. Features a teach mode for simple programming, and
can control both roll adjustment and rotation simultaneously, if required. As an option another two axes can be controlled by the CNC. The controI is available for all models.

SPECIAL ROLLS
Rolls for pipes. Each set of rolls can be designed for two different sizes of pipes. Combined rolls for I and U beams the easy way, adjustable for all different sizes covering the capacity of the machine. Rolls and guiding unit for bending of I and U beams the hard way. Rolls for high production of rings by spiral bending of flat bars, pipes and other profiles. Rolls and spiralling device for production of spirals, with a certain pitch and diameter from flat bars and pipes. 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 via low speed hydraulic motor. Bending rolls for pipes. One or two pipe diameters per set. Bending rolls combined for I and U beams the easy way. Bending rolls and guiding unit for bending of I and beams the hard way. Bending rolls for round bar. Spiral bending rolls for production of rings from flat bars or pipes. Spiralling device for production of coils and spirals from pipes or flat bars. Bending rolls for other special sections. Portable push button control for all functIons. Digital display showing the positions of the lower rolls.
