8.2 BENDING
Prepare the station as described in 6.1
Equip the station with a mandrel [1b] and a measuring insert [1a] and enter
the settings as described in item 6.3
Move the rail into the bending space and move the rail to the bumper S2
Press the pedal Q3 to start the bending procedure; after the operation is
complete, the piston rod will return to its starting position.
To repeat the operation, release the pedal and press it again.
NOTES:
The mechanical properties of rails made of copper or aluminum may vary -
different cross sections have different moment of inertia; this may result in different
bending angles. The property is particularly linked to the moment of inertia of a cross
section. In order to perform precise bending, bend a rail by an angle which is smaller
by 5-10° from the target value and measure the angl e with a measuring insert.
Calculate the difference between the desired and the obtained angle. Then bend the
rail again, adding the calculated adjustment value to the target angle.
There is a risk of damaging the piston rod if the bending procedure is started
before the station is properly equipped.
