Tailor drawn tubes
from Bültmann
AGAINST the background of increasing requirements for
lower weights in the automotive industry, the TDT technique
becomes more and more important when producing tubes,
according to Bültmann GmbH.
The current methods for the production of these specialist
tubes can only be applied experimentally and are therefore
very labour-intensive.
The increased demands for narrow tolerances can only
be fulfilled by the current techniques with great difficulties.
Furthermore it is not possible to achieve a “steady” process
reliability when basing on today’s technology.
Due to the numerous influencing parameters in TDT
drawing technology the tube drawing process currently
applied will very soon reach its technical limits.
Intensive development work and positive practical
experience enables Bültmann to assist its customers in
combining theory and practice. The patented TDT Production
System from Bültmann in conjunction with the Bültmann
draw bench technology can now be implemented in the tube
production industry.
When developing the TDT tube drawing technology
Bültmann attached greatest importance to the possibility to
use technological components which have already been
used for other applications.
In order to achieve very narrow tolerances, especially
in the transition zone of wall thickness, and to ensure the
necessary process reliability at the same time, a closed
control circuit is indispensable. This process control is
assured by combining sensible and dynamically reacting
drive systems and specially designed measuring devices
and process software.
When harmonizing both components, a precise, reliable
and user-friendly control of the TDT process is possible. In
addition to the necessary drawing equipment Bültmann also
offers a complete process consulting service for the TDT
applications.
