2.04.04 BENDING OR STRAIGHTENING
This type of machine can bend-straighten in both directions of travel ( refs. A and B in fig.
3A ). The hook die ( ref. 2 in fig. 3A ) can work when both pushed and pulled.
More force is generated when pushing the tool ( ref. A in fig. 3A ) than when pulling it.
• Position the rod that it lies firmly on the base of the head and on the rollers ( ref. 1
in fig. 3A ) and perpendicular to the longitudinal axis of the machine (fig. 3A).
• After correctly positioned the work piece as indicated in fig. 3A, move the double-
acting lever to “ open “ or “ close “ as required;
• press the start button and hold it down until the bending or straightening operation
has been completed;
• Once bending or straightening have been completed, move the piston slightly in
the opposite direction from that required ( always with the help of the double-
acting lever and the start button ) in order to release the material and remove it
from the head.
The following picture (fig. 3A) is only an example
Fig. 3A
The following simplified diagram shows how bending and straightening operations must be
performed.
See Fig. 2C and Fig. 2D.
