Angle Rolls

Hot Rolling Zirconium Pushes Possibilities

British engineering company Charles Thompson Ltd breaks ground with a scarce source possibly never seen before – a heat exchanger component rolled from an unusually thick (40 mm) flat plate.

Angle Rolls: Industry News

D&S Manufacturing Installs New Angle Roll

The 308HV4 Carell double initial pinch universal roll bending machine is equipped with three driven rolls. The three shafts are each driven with a direct coupled hydraulic motor and planetary speed reducer offering 100 per cent efficient torque delivery. Powered movements on lateral material guides have been added for increased accuracy and efficiency. The double pinch unit allows for reduced operator handling by pre-bending both plate ends without removing the part.
The Carell double pinch angle roll increases their in-house fabrication capabilities and increases roll bending range.

Trilogy Machinery Named Distributor for SweBend

The innovative CNC control called “Seven” from SweBend has gained widespread acceptance and has even been retrofit on older bending rolls manufactured by their competitors so those shops can enjoy the latest technology on their older machines.  
They are now the exclusive North American distributor for SweBend angle and section bending rolls, plate rolls, and specialty machinery.

All Bent Into Shape

The Haeusler ROLLmeister Plate Roll TETRA series from Sterling Fabrication Technology is ideal for medium and large batch production of shell and tube heat exchangers and pressure vessels with a small-to-midsize range of wall thicknesses, as well as economical single shell production. 
Here is some of the newest equipment and tooling used to bend sheet metal and plate steel.

High Bending Force for Thick Plates

Using the CNC control “Seven,” the PB4 machines with four rollers are ideal for high volume series production.
PB plate bending machines from Schwarze-Robitec are ideal for precision bending of up to 200 mm thick plates for energy or offshore applications. 

Unique 4-Roll Plate Bending Machine for Producing Cylindrical and Conical Shells

The supporting yoke clamps the top and bottom rolls and compensates for deflection by applying counter pressure to the rolls. This enables the ability to install a top roll with a smaller diameter, which can then allow bending of smaller inner pipe diameters.  Camber adjustments at the rolls are no longer necessary as bending capacity turns into pre-bending capacity, eliminating the need for predefined production programs. This increases the machine’s flexibility and reduces change-over times for exchange rolls. Companies can now form plates without limitation, from smaller thicknesses to thicknesses of up to 150 mm.
The supporting yoke design on this 4-roll plate bending machine from Graebener-Reika can be hydraulically adjusted to counteract the respective bending forces, enabling processing of a wider variety of material thicknesses for multiple competitive advantages.
