Cold-formed hollows for automotive application
Cold-forming replaces multi-step manufacturing
processes, while cycle time of
one second sets new standard.
Tube 2020 trade fair will see the unveiling of
AMBA’s new cold-forming machines for hollow
ends. Thanks to their unique operating
principle, these machines guarantee precise
alignment of the hollow ends, while achieving
highest throughput rates.
In order to ensure a perfect, backlash-free
fit of the hollow ends in the receiving mounting
part, the hollow ends have to be manufactured
with paramount precision. It is critical
for the hollow ends to be perfectly aligned in
the axial direction in order to preclude any risk
of the components being distorted during the
assembly process. Until now the hollow ends
used to be shaped by machining, or as weldments
to achieve the desired shape of the
hollow ends. However, with those methods,
production rates of up to 60 items per minute
were not realistic.
In contrast to this, the new RH 08 synchronous
machine from AMBA forms both ends
simultaneously. This operating principle
The hollow sections are fed from a magazine (top), up to 60 pieces per minute leave
the machine ready for installation (Picture: Aachener Maschinenbau GmbH)
ensures that during forming both hollow ends
stay perfectly aligned with each other. With a
cycle time of approximately one second, the
machine achieves an extraordinarily high output.
The hollow sections leave the machine
ready to be installed, requiring no additional
machining.
The first machine of this type – which will
be supplied in the spring of 2020 to a component
manufacturer for the automotive industry
- will be designed with upsetting force of
up to 25 t at either end, enabling the machine
to process steel and stainless steel hollows
with outside diameters of up to 20 mm. The
two forming stations arranged in the axial
direction of the work piece feature fully automatic,
high-precision positioning systems,
which allow for hollows in lengths between
450 and 800 mm to be processed on the
machine.

Premiere of ecoMetals tours on the occasion of the wire and Tube 2020 trade fairs in
Düsseldorf
Sustainable, eco-friendly, energy saving
and innovative: this is how most manufacturing
companies wish to come
across to the public.
However, the road to reach this goal is a
long and winded one, especially for
resource-intensive technology companies
in the wire, cable and tube industries. It
often takes companies years to comply
with the requirements relating to climate
efficiency, sustainability and resource-saving
processes.
All the more reason why Messe Düsseldorf
is now focusing on an ecoMetals
campaign during the leading international
trade fairs wire and Tube: for the
entire duration of the trade fair from 30
March to 3 April 2020 there will be guided
tours – so-called ecoMetals tours –
offered to the stands of exhibitors who
produce in a sustainable manner that
saves resources and cuts emissions.
Exhibitors will inform participants on
the ecoMetals tours personally and in
detail about innovations at their stand.
The guided information tours are free of
charge and will start at the ecoMetals
information counter at the Nord
entrance.

Tube 2020 accompanying programme: Tube Experts Meeting and TubeForum
At the Tube 2020 trade fair, stahlnews.de
will be organizing the Tube Experts
Meeting on the evening of the first day
of the fair, March 30, 2020 (hall 1, room
15 – start at 6 p.m.).
Under the motto “Materials, technologies
and markets – the future of the tube industry“
renowned and recognized industry
leaders have registered their presentations,
amongst others Antonio Marcegaglia,
Chairman and CEO Marcegaglia Group;
Hanns-Jörg Westendorf, CEO Hoberg &
Driesch; Dr. Dirk Bissel, CEO Vallourec Germany.
After the course of presentations
attendees will have ample time to network.
In addition, the TubeForum will be
conducted on Tuesday, March 31,
2020. With the same slogan, the
event will take place also in Hall 1,
Room 15, from 2 to 5 p.m. Selected
exhibitors will give a 30-minutes presentation
about the company and its
products.
