B3 - 3-roll plate bending

3-Roll Double Initial Pinch

Capacities ranging from 1.5 metre to 3 metre and 3mm to 70mm.

The Biko B3 three roll double initial pinch bending roll machines, are manufactured with capacities ranging from 1.5m to 3m and 3mm to 70mm, and have been designed to achieve the most versatility in a traditional industry.

With all three rolls independently driven by independent motors and gearboxes, two powerful hydraulic cylinders to each roll and a hydraulically operated drop end bearing for the removal of completed cylinders, the machine has the capabilities to produce high quality rolled parts and as a result of its low competitive cost is the preferred machine of the general fabricator, who needs the assurance of a strong and user friendly machine. General fabricators are the main users of this product.

Within our range the Biko B3 offers the maximum rolling power with the minimum investment cost.

HOW IT WORKS

Introduce the sheet between the rolls
Simultaneously lower roll C and raise roll B. Then using a series ot step raise roll C to torm the pre-bend
Repeat steps 1, 2, and 3 for pre-bending the second edge
Then simultaneously lower roll B and raise roll C
Position the rolls in standard pyramid configuration and close the ferrule.

ACCESSORIES

TOP/CENTRAL SUPPORT:

When rolling thinner material to larger diameters, the rolled part has little inherent strength and has a tendency to collapse, the result an ‘egg’ shaped cylinder. It is normal workshop practice to support the work piece with either a fork truck or overhead crane, which ties up valuable equipment and could create a ‘bottleneck’ in production.

PROFILE DIES

Profile dies can be mounted on to the machined extended roll shafts outside the drop end bearing. These can be adjusted according to the profile shape (T U Flat)

NUMERICAL CONTROLS

Various types of automated controls are available for the bending sequence, from the basic NC with simple NC to the full graphic CNC with auto calculation of the bending programmes.

Accessories available on this machine:

Induction surface hardened rolls;
Cone rolling package;
Profile bending dies;
Digital displays;
Top supports;
Side supports.
