6.1.1 Tools and dies replacement
General rules to be followed when changing tools and dies.
Make sure there are no profiles or machining residue left in the insertion recesses before proceeding to change
parts .
Move the machine to its end of travel in order to insert the tool into the die and disconnect the air supply, make
sure the cylinder does not have enough energy to move it self, pushing the operating device (pedal and/or valve).
Change the used components being careful to divide equally the backlash/play between the tool and die, check the
condition of all the nuts and bolts and if necessary change any that require it.
Caution before to put in function again the machine, assure that:
all parts substituted and/or the tools used to carry out maintenance must have been removed from the insertion
machine
any safety guards removed or open have been correctly replaced and fixed.
Switch on the air supply again, check for any leaks in the punching machine pneumatic circuit and carry out few
empty cycles.
Repeat the empty cycle test using profile offcuts to check the calibrations.
