6. FOLDING GROUP REGULATION
Because of continuous use of the press brake it may happen that the machine does not make the same
bending angle on the right side than on the left side.
When this happens it is necessary to scale this part by using a lever on the left of the machine and follo-
wing the steps below:
• Prepare a few metal sheets with dimensions of 100x60x2 mm thickness.
• We removed the left frontal protection to expose the regulation lever.
• We place the die with the 16 "V" which is corresponding to a sheet 2mm thickness..
• We adjust the machine to make a folding operation wider than 90º. 120º is a suitable angle to observe
differences.
• We place a plate at each end of the die, respecting both are at the same distance from the end and the
bending length is the same.
• We make a folding operation with the sheets and compare one another, taking into account which is
which. If we see that the plate on the left is more open than the one at the right, then we must lower the
lever to force the ram down and close the angle. Otherwise it will be necessary to lift the lever to force the
ram up and open the angle.
• We loosen the fixing screw, move the lever, then we press the lever fixing screw and re-check.
• Repeat the above operations after each test as several attempts are often necessary before getting the
optimum position.
• Once the Folding group (Tranche) has been adjusted, fasten the fixation screw to fix the lever and pro-
ceed to the assembly of the cover sheets.
CAUTION
Never move the adjustment lever while the folding group is forcing against the die.
