• Place the inversion pin into the disc holes to set the bending
angle. Considering position 0 as the limit-switch position, the
pin must be placed approximately according to the disc rotation
direction.
• The exact angle can be found after some bending tests, using
the regulation handle for some little angle corrections.
• After the pin insertion, place the iron bar to be bent on the working
plate and start the machine pushing the pedal; in this way the disc turns
and the bar is bent, until the pin touches the limit switch. When the
pedal is released, the disc turns back into the starting position.
• During the bending operation the pedal must always be pushed, since when it is released the machine
stops immediately.
• If the pedal is pushed during the return of the disc, it stops immediately in the position where it is.
8a.4 How to cut a piece (only for combined machines):
All the below-described operations must be executed with the working plate free of any kind of tooling.
• Connect the supply cable as above described.
• Turn the main inverter-switch from the starting position 0 into position 1 or 2.
• Insert a pin at 180° from the point 0.
• Push the reset button: now the light is on.
• When the machine is stopped and the disc is in the starting position, le blades are completely open.
Insert the bars to be bent into the space between the blades under the shear protection, and put
them at the required length. Execute the cutting operation through the remotely-controlled pedal,
keeping it pressed till the end of the cutting operation and automatic disc return
– which is settled
according to the pin position.
Repeat the same operation for each cutting execution.
8b
Use of the machines with the panel 9x9 and the speed variator:
• The panel was designed to allow the operator to execute a bending sequence without stopping and
move the pin. In this way, a lot of time on the production can be saved.
• The speed variator allows the operator to choose the number of bending-disc turns.
