Haginger GmbH & Co KG are the
manufacturers of drawing machines for
drawing tube, rod and profiles in copper,
brass, aluminium and super conductors.
For the drawing of super conductors, the
company has developed a new, special
handling system.
In the planning of the company’s drawing
plants, particular attention was paid to
ergonomic and easy working conditions.
The draw operator has a vantage point to
view the separation, plugs and drawing
die and thus control the tubes before they
arrive at the collecting stanchions.
The charging device, usually the loading
drum, is equipped with perfectly operated
drivers. This ensures that the piercing stem
is supported for easy lining of the tubes,
requiring no operator intervention.
The plugs are rotating, and the operator
can thus control the whole surface of the
plug. The piercing stems are supported
directly in front of the die, so there is no
danger of the plug falling into the dies. The
die frame is supplied with a drawing block,
with availability of a second drawing block if
desired. In this case one drawing block can
be supplied with dies, with the second used
for drawing.
A semi-automatic handling system can
be used to manipulate the drawing block.
Meanwhile, the whole working process can
be controlled from the operation desk.
If short drawing lengths are desired, the
drive of the straight drawing machine
is undertaken with hydraulic cylinder
or spindle. If long drawing lengths are
desired, the drive is undertaken with chain
or gear rack. The drive with gear rack has
the important advantage that the push is
dampened because of the big mass of the
gear rack. Therefore, drawing is carried out
with less vibration and noise.
