Cone (taper) bending
If the machine is equipped with cone bending
equipment, it is very important that such opera-
tions are carried out as follows:
1. Raise the trailing shoe so that it rests against
the lower roll of the machine. Place it in a
suitable position within the working range of
the machine (stop rings on both sides of the
shoe are loosened, the shoe is moved and
the stop rings are tightened again after the
adjustment). NOTE: Always try to work in the
middle of the machine.
2. Set the bending roll machine in its lowest
position, if the small diameter of the cone
is directed against the swing-out side of
the machine. Read the value shown on the
handwheel with dial register (this in order to
obtain parallelism when resetting the ben-
ding roll after finished bending).
3. Pull out the sleeve of the shaft coupling, raise
the bending roll by means of the handwheel.
The worm screw of the stand on the left-
hand side is now disconnected. The screw
in the stand on the right hand side is now
connected and the bending roll is raised to
the required position, dependent upon the
shape of the cone (the trailing shoe is now
placed close to the swing out side).
If the bending should be carried out with the
trailing shoe placed at the stand on the left
hand side, the bending roll must be raised
here and lowered at the right hand side.
4. The machine is now adjusted for the bending
of precut cone pieces (when cone bending
it is adviseable to prebend both ends of the
sheet).
5. When bending, check that there is always
room for the material to move in the
machine.
6. Adjust the lower roll with arbitrary pinching
force (not too hard setting). The sheet must
be able to move between the rolls.
7. Introduce the straight edge of the precut
workpiece between the rolls, with the small
radius turned against the head of the trailing
shoe. Start the machine by means of the
foot switch and let the sheet slide against
the trailing shoe at the same time as it is fed
forward and bent against the bending roll.
NOTE: When cone bending always run
the machine “Forward”. Check that the
bending is carried out as per requirement. If
adjustment of both sides of the bending roll
is necessary, the sleeve of the shaft coupling
must be connected so that both worm screws
of the machine are actuated. Do not forget to
check the setting of the dial register.
8. Run the workpiece through the machine,
then reset the bending roll. Now bend
once more and continue until the cone has
obtained the correct shape.
9. After cone bending reset the machine in its
initial position, so that ordinary cylinders can
be bent.
NOTE! Important when
setting the bending roll
diagonally
Do not set the bending roll diagonally so
much that it has a pinching effect against the
top roll in its raised highest position. This to
avoid overloading of the bending roll, as the
movement of the roll results in a cutting ef-
fect. At worst the top roll can break resulting
in severe injuries.
