Safe shaping instead of expensive welding

Process integration for spherical head sealing on steel and stainless steel
tubes


In the automotive industry spherical heads are used as sealing and connecting ele
ments for
pressure tubes. Up to now, these sealing elements have been produced mechanically and
subsequently connected with the respective tubes through welding or soldering. This process
is not only cost
-
intensive, but can also result in weak points in th
e welds. Facing this
challenge, transfluid Maschinenbau GmbH has developed an integrated method. Result: Cost
-
efficient and safe forming of spherical head systems directly to the tube.


"There are two different types of spherical heads. Round
-
shaped with a

purely metallic
sealing function, and sealing cones with a 24° cone. These can seal both metallically and/or
be fitted with an O
-
ring", explains Gerd Nöker, CEO of transfluid.

"Our systems represent a new, efficient shaping technology and extend the scop
e to new
rationalisation processes." The new combination machines enable not only material
compression, but the surface can be also processed with high rolling precision.


Essential technical factors

For cost reasons, the wall thickness

of the tubes must
be correspondingly small. To be able to
implement this, transfluid offers the possibility to increase the wall thickness in the area of
forming


for example for stainless pipes of 8 x 1 mm to a wall thickness of 2.6 mm. Very
small tolerance is allowed for

the formed geometry. Our special endforming machines are
therefore equipped with a controlled positioning system allowing for extremely precise
shaping. This is vital especially for the rolling machine. To achieve an optimum result, it is
essential that t
he surface on the spherical head is as smooth as possible. Here, the machine
and tool technology from transfluid enables surface shaping of Rz 0.5 on spherical heads.


The cost saving is enormous: up to 45 percent. To avoid the situation when conventional

methods hamper any further progress, transfluid will consequently continue investigating and
developing new possibilities in process integration also in future.
