Vol. PB-7
BASICSDue to the mandatory safety measures, safer tool mounting methods have become widespread due toimprovements in laser beam safety devices and clamp systems.
For this reason, work accidents have been reduced, but we think that some people still haveexperience such as “The hand slipped and was dangerous.”
Don't think that "The accident at the time of mounting is not important", please review again and try towork safely.

Depending on the type of intermediate plate and clamp, the number of cases where the punch is“front-inserted” and “front-removed” is increasing, but this time we will focus on horizontal insertion
to emphasize safety. Follow the steps below to install the tool.
[FOR 2V DIE]
1. Attach the die holder to the lower table.
When mounting multiple die holders, keep
the distance between the die holders at least
5 mm.
Open 5mm or more

2. Fix so that the die holder step and the V grooveof the die to be used are on the machine side
(rear side).
If an accident occurs and the die breaks,
this is a measure to ensure that it does not
scatter to operators.

3. Loosen the tightening bolts attached to the die
appropriately, insert the die so that it slides infrom the operator side, and adjust it to theapproximate position.

4. Since pressure is required at the time of centering,
temporarily tighten the bolts at a position 3 to 5 mmopen between the intermediate plate and the punch.

[FOR 1V DIE]
1. The die for thin plate (V-width less than 32mm) can be mounted on various types of die holders.
2. The die for thick plate (V-width 32mm or more) is directly mounted on the lower table.
However, it may be necessary to attach a die block holder due to the stroke and open height.
* As a common matter, the lower part of the table and the rear part of the die holder base must notbe loosened as it is a standard for aligning.

Lower table[FOR PUNCH]
1. After attaching the die, place the cutting edge of the punch in the V-groove of the die to be used,and slide it to the desired position.
2. After insertion, tighten the front bracket so that the punch does not drop.
* If the punch and die are fixed by shifting the left and right positions by about 5mm, it will prevent
scratches.
3. At present, the one-touch type has become widespread, and mounting from the front is also possible.
However, heavy punches are mounted by sliding in the procedure 1 instead of inserting them fromthe front for safety reasons.

Holding the underside of the punch
may cause injury if dropped.
When mounting from the front,
be sure to hold both ends of thetool.

(Excluding one-touch type) * For details, follow the procedure in the machine's instruction manual.
1. Operate the machine with the punch and die attached, and apply a pressureof about 1 to 2 tons.
Adjust the amount of pressurization according to the tool length.
Watch out for too much.
2. While pressurized, tighten the bolt completely to fix the punch.
3. Thereafter, the tightening bolts of the die are completely tightened and fixed.
4. Release the punch and die slowly and check that the punch and die are notloose.

* If the edge angle between the punch and the die is different, or if the tip R of the punch is smaller thanthe V bottom R of the die, misalignment may occur.
In the case of such a aligning, it is better to sandwich paper (newspaper) etc. and tighten the die.
