Continual innovation of mandrel bending

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

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.

› Star Bend’s latest bending model, the Star 450 CN6

Exclusive 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. patented
