Roundo R1 section bending machine

SECTION BENDING MACHINES R1
All models of ROUNDO Section Bending Machines are designed and built according to the latest technological experience in this field. Material and components have been thoroughly 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. The three bending shafts and all other shafts are journalled in heavy SKF roller and ball bearings. All three rolls are, irrespective of adjustment position, driven by a worm gear motor. The central roll 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 rolled. The two lower rolls are individually and hydraulically adjusted by means of a motor driven hydraulic pump. The hydraulic unit is protected against overloading and non return valves eliminate the possibility of the lower rolls changing position during the bending operation. The drive and method of adjustment of the ROUNDO Section Bending Machines give them a unipue and universal range of capacities with pre bending of both the leading and trailing edges without the need to remove and turn the section being bent and with a minimum of losses in material. As standard the machines are operated by portable push button controls for roll rotation and by hand levers for the adjustment of the lower rolls.

STANDARD ROLLS
Bending rolls for flat bar on the flat and on edge, angle bar leg out and leg in and T bar leg out and leg in, are supplied as standard rolls with the machines. The rolls are through hardened and located on the shafts by means of a single key, thus making it easy to adjust and change over to 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 indicating the position of the lower rolls, are standard equipment.

STANDARD EQUIPMENT
Horizontal bending shafts.
Three roll drive.
Compensating slip clutch for the top roll.
Oпe set of standard rolls for flat bar, angle and
T sections and square bar. Guide rolls for bending of asymmetrical sections. Portable push button control for roll rotation. Scales showing the positions of the lower rolls. Emergency stop palm button. Complete set of adjusting tools. Operator's manual and service instructions.

SPECIAL ROLLS
Special rolls for 1 and U beams, leg out and leg in.
Pipe rolls with one or two dimensions per set of rolls.
Rolls for production of rings by spiral bending of flat bar and pipes as well as other special rolls are available on request. The machines can be equipped with a spiralling device for production of coils and spirals, with different pitches and diameters, from pipes and flat bars.
Special rolls for all types of sections can be supplied.
In some cases the rolls are made of a special material, such as nylon, to avoid marking and tearing on easily damaged sections

OPTIONAL EQUlPMENT
Combined horizontal vertical design.
Bending rolls for pipes. Two pipe diameters per set.
Bending rolls combined for I and U beams.
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. Push button control for all functions. Bending rolls for other special sections.
