Operation
General
•
Your tool is capable of many different types of bending operations. Materials that can be bent
include steel, iron, brass, wrought iron, and aluminium.
•
To determine how to properly set up the tool, you must first determine what type of bend you
want to perform. Round shapes, angles, or spiral operations are each described in the follow-
ing sections. The numbers in brackets refer to the reference number in the exploded view of
the parts.
•
Please note the “spring
-
back properties” of certain materials when performing the bending op-
erations. This assumes that you overbend the material to a certain extent to achieve the de-
sired degree of bending. Different materials have different degrees of spring-back. Perform a
test bend to determine how much “spring
-
back” you need to compensate for.
Note!
The bending machine must be fixed on a safe surface before being used.
Bending round forms
1. Make sure that the mounting plate for dies
(4)
is attached to the mounting plate of spring-
forming die
(32)
of the device. See Fig. 1 to know the positions required for bending round
forms.
2. Make sure that the stop
(2)
is loose.
3. Move the vice unit
(5
–
9, 15)
on the mounting plate holder all the way to the end.
4. Screw the mounting shaft of round-bending die
(28)
on the mounting plate.
5. Set the round-bending die
(29)
on the mounting shaft.
6. Move the bending block assembly
(16, 17, 22
–
24)
to the very end. You might have to loosen
the bending block locking plate
(21)
by loosening the hexagon screws
(20).
Do not secure the
locking plate at this moment.
7. Set the stop against the round-bending die and close the vice so that it clamps the workpiece
against the die.
8. Move the bending block until it touches the workpiece and until its front plate
(16)
is flush with
the vice surface
(8).
Secure the bending block by tightening the two screws.
9. Move the bending block to the left using the handle
(27)
until reaching the desired bending
angle. Consider the “spring
-
back” effect.
10. Should you wish to repeat bends at the same angle, firmly tighten the stop at the spot where
you have finished the bending operation.
