2007

Dynobend, Netherlands, has launched its

latest development: the combi-bending

machine. The complete line of combi-

bending machines consist of the CB12,

CB25, CB40, CB60, CB76 and the CB90.

Equipped with servo drives, this CNC

bending machine combines the advantages

of rolling with variable radii and the popular

mandrel bending technique.

The patented Dynobend bending tools,

which are horizontally divided and vertically

clamped, can be used to bend fixed radii

from approximately 1.2 x D to 3 x D. The

rollers can also be used to roll larger radii.

In combination with the compact bending

head, there is a capability to bend many

different types of products.

All kinds of tools can be used together

with the fixed tools, eg multi-ball mandrel,

wiper die and pressure die. All machines

are equipped with a booster, modem and

network connection. By using the correct

tools, in addition to

tubes it is possible

to bend rectangular

tubes

and

other

profiles. Furthermore,

different types of

materials do not

present a problem.

The machine can

easily be extended

for mass production

by adding a bunker,

loading systems, weld

seam detection, and

unloading

systems.

The bending machine

therefore plays a central role in the production

unit. This enables large savings to be made in

relation to handling and operator costs.

Spinformed hollow tube

technology replaces

end-cone welding

Formitt Metal Labs, a division of Hess

Industries Inc, offers development,

prototyping and production runs that utilise

patented technologies to form tube ends,

while eliminating welding of end-cones.

The division was created specifically to

support product development for a variety

of industries.

The company uses spinforming, flowforming

and assembly technologies to create hollow

tube symmetrical and asymmetrical shapes,

fabrications, and assemblies. The method

accommodates tubing in both ferrous and

non-ferrous metals, including stainless and

high alloy steels.

By eliminating the need to weld end-cones

to a tube, spinforming technology enhances

overall component quality, reliability and

cost. The company’s hollow tube fabricated

assemblies can include the insertion

of filtration elements, heat exchange

components, catalytic elements, or others.

Formitt metal tube spinforming technologies

are currently being used in the automotive,

HVAC, filtration, marine and other

industries.

Latest star in the electronic bending range

Star Bend, Italy, produce electronic bending machines without bending hydraulic

transmission. The range includes thirteen different size configurations, from the simplest

one axis model up to the complete model 6/8 axis CNC, which can bend seven sizes of

tubes from Ø 6x1mm to Ø130x8mm.

This new system, managed

by brushless motors, is

controlled by the latest

generation of digital drivers

and uses the proprietary and

exclusive ‘bending cycles’

management

software

operating in a Windows

environment. This ensures

a line of machines with the

most reliable performance,

purchasing

costs

and

managing costs.

Exclusive

patented

Star

Bend design allows the machine to be entirely modular with the maximum capability

for updates. It is able to interface with any other bending machine, and can interact

with the laser 2 measurement centre laser 2. This interaction is undertaken by remote

workstation or modem with tele assistance.
