To actively promote the development of solar technology. That was the aim set by members of the Working Group for Environmental Technology (Arbeitskreis für Umwelttechnologie) in Pforzheim when, in 1991, they organized a one-day event with presentations on the use of solar energy. Five solar companies presented their products there as part of a small exhibition. Over the years that followed, interest in solar technology grew and in 1993 the event attracted 25 exhibitors to Pforzheim, a town situated between Stuttgart and Karlsruhe, with 84 companies present in 1995.
These companies made the event Germany’s most important exhibition for solar technology, and gradually organization of the event became more professional. As CEO of the newly founded Solar Promotion GmbH, Markus Elsässer, who was there at the beginning in 1991, raised awareness of the solar exhibition beyond Germany’s borders.
There will be also Tauring Group that will promote, between others, its hydraulic pipe bender.
The exhibition attracts exhibitors and experts from an international audience and focuses on promoting the development of solar technology. The Intersolar Europe Conference also provides market and technology insights and is organised simultaneously.

BENDING WITH BALL MANDREL AND WIPER DIE
When the radius of the bend is smaller and/or the wall is thinner, it becomes necessary to use a
ball mandrel and wiper die. The wiper die is used to prevent wrinkles. The ball mandrel performs like a plug mandrel. The balls are used to keep the tube from collapsing after it leaves the mandrel shank.
Bending issues are enlarged when making tight bends or with thin wall tubing. It becomes more difficult to retain the material during compression.
The pressure is so intense the material is squeezed back past tangent and buckles. This area must be supported so that the material will compress rather than buckle; this is the prime purpose of the wiper die. Note, the wiper die cannot flatten wrinkles after they are formed; it can only prevent them.
Bending thin wall tubing - requirements for the bending of thin wall tubing with tight radius bends of centerline radius equaling the tube outside diameter have become more common in recent years.
To increase the problem, new alloys have been developed that are extremely difficult to bend. The proper bending machine, good tooling, and a trained operator can make all the difference.
To facilitate this type of tube bending, the material to be bent should receive special consideration. To help maintain the consistency of the tubing dimensions and characteristics, the entire material required for a given job should be acquired from one supplier, preferably even from the same lot or heat number. Premium-priced close-tolerance tubing should be considered. It often saves many more times its added cost. It may be necessary on occasion to size certain tubing before bending.
There are many pipe bending machines but only a few are capable of thin wall, 1 x D bending.
Even those machines best suited for this special bending must be in excellent condition and of a size large enough to assure rigidity. The machine must be capable of retracting and advancing the mandrel with the clamp and pressure dies closed. A hydraulically actuated pressure die is desirable. One feature of this system is that it provides identical pressure on the tube regardless of wall variation.
A pressure die boost counteracts the drag of the pressure die, mandrel and wiper die. It pushes the tube into the bending area, preventing excessive wall thin out.
Without a pressure die boost, the thinning that normally can be expected is about three quarters of the elongation of the outer wall. Companies specialized in steel bending automation for a broad array of fabricated products, includes CNC tube benders, tube measuring equipment and complete cellular integrated systems.

TOLEXPO – 15-18 November 2011
A partnership with the Midest and Maintenance Expo to create:
· a communication synergy promoting the sector
· a technological showcase bringing together subcontractors' and equipment manufacturers' know-how
The 4th edition of TOLEXPO, the international show for sheet metal, coil, tube and section
equipment, organized by DBR Event will be held at Paris-Nord Villepinte Exhibition Centre from 15 to
18 November this year. As the economic recovery begins, Tolexpo confirms its position as an
industrial event firmly dedicated to the sector and confirms the success it has achieved, with both
exhibitors and visitors, since its creation in 2005.
6 months before the show opens, Tolexpo already has more than 200 exhibitors, among them both French leaders in the sector and the majority of foreign manufacturers, between them there is also Tauringroup which is a world leader in tube and pipe bending machines.
Almost 11,000 targeted visitors looking for new equipment will discover the products and technical innovations offered by suppliers at the show.
At Tolexpo, visitors will find solutions to all their needs, whether they are looking to renew or modernize their equipment, begin using new technology, improve their productivity, bring their businesses into line with standards and regulations, etc.
For the first time this year, in partnership with the Tolexpo show, Tôlerie magazine is organizing a
competition for students in the various areas which involve sheet metal working.
A Challenge which will bring students together: the Tol&Design Challenge has been created to put the spotlight on the expertise of young people who have chosen the various subjects which involve sheet metal working, and aims to promote these subjects and the production chain itself, by bringing students together to work on an industrial project.
It is also an opportunity for the students to present their expertise to industry professionals by
creating finished products - in this case a chair - using precise specifications.
An initial analysis of the applications shows that students are particularly committed to this project
which is closely connected with the world of work. Teamwork, together with the students' fabulous
motivation, gives them the opportunity to bring their apprenticeships to fruition by carrying a
project through from A to Z.
The organizers of Tolexpo, Midest, the global sub-contracting show and Maintenance Expo, the
maintenance solutions show, are continuing to work together in order to create communication
synergies and boost their industry sectors.
The major objective is to create a technological showcase which will bring the expertise of subcontractors together with that of production equipment manufacturers.

PIPE BENDER
Bending machine is fabricated from 30mm square section tubing to provide a rock solid frame which more than stands up to the rigors of daily use. The frame is designed to give maximum stability, minimising the risks of sideways movement or skidding across floors, making operation as easy and effective as possible. The formers, which are key to creating a perfect bend, are machined cast aluminium. This means they can provide a superior and highly accurate bend as the machined area provides a perfect profile to support the pipe and gives excellent contact and virtually no movement. By comparison, most other brands use non machined die casts. Included with all machines is a dual purpose stabilising and extension bar. It can be used to give extra leverage when performing down-bends, or to give extra stability to up-bends by acting as a counter-lever. For electricians, the bar can also be used as a handy cable reel feed by simply securing it through holes in the vice mount, further adding to its versatility. When not in use the bar can be stored securely out of the way on the side of the machine. Another important development on this range of machines is the new design vice mount. Being more substantial than those of other brands, this vice mount offers added functionality. Perhaps most important is the ability to accept a wide range of vices, including those of other leading manufacturers, thanks to the universal slots. These slots are also designed to allow the vice to be secured either flush with the edge of the mount or even to overhang, in order to provide clearance to make the threading of conduit much easier, no longer making the vice mount an obstacle to the threading equipment. Yet another exclusive feature in this range comes in the form of the hexagonal drive featured on the universal and pipe bending machines. A full range of spares and accessories are available. These all have the advantage of being compatible with the equivalent machines of other leading brands. For ease of transport, a wheel kit is also available which can be attached to the bottom of any machine in the range, as well as those of other brands
In conclusion the company is a leader manufacturer of pipe bender and tube benders and has strong experience by building firm partnerships with its partners and customers around the world. This bending machine allows the pipe bending of sheet metal to form box and pan shapes, and to form bends and creases in sheet metal.
