Operation
2.1
What should be remembered when starting work?
a)
Turn eccentric shaft (55) with screw driver.
b)
Check if dipping depth of punch is all right (see point 3.2, i).
3.
Maintenance
3.1
What points should be noted when operating the
profile nibbler?
a)
Always lubricate line of cut with of cut with oil in case of steel sheet and with kerosene in case
of aluminium sheet. If punching and nibbling oil (ordering No. 20198) is used, the punch life
can be increased when nibbling steel sheet.
b)
Check whether punch and die are sharp. Die must also be sharp on its face where it supports
the sheet.
Never nibble with blunt tools!
c)
The nibbler works more smoothly if it is slightly lifted during operation.
3.2
What should be done when the punch is blunt? A
a)
Undo set screw (78) approximately 4 turns.
b)
Withdraw tool head from housing.
c)
PN 4360 unscrew punch (65) from connecting rod pin (63).
PN 4361 unscrew punch (65) with its lower extension (68) from upper extension (74).
d)
Regrind face of punch (65) and bevel at the rear at longitudinal groove.
e)
Be careful that punch does not become shorter than the min. length (61 mm=2.44 in). Shorter
punches are unserviceable.
f)
Dress cutting edge slightly with oil stone.
g)
PN 4360 Screw punch into connecting rod pin.
PN 4361 Screw punch with its lower extension into upper extension.
h)
Slide tool head into housing (dismantle punch guide). Centre and secure with set screw (78).
i)
Turn eccentric shaft (55) with screw driver. At the same time check dipping depth of punch.
Punch should dip approx. 1,0 mm (.02 to .04) into die.
k)
Retighten set screw after a short nibbling distance (78).
PN 4361
B
When changing the punch, take care that punch (65) is firmly screwed into punch extension
(68). The same applies to fastening of punch extension (74) in connecting rod pin (63). Screw
in firmly punch extension (74) by means of an 8 mm fork wrench. See fig. page B.
The fine-pitch thread between the two extensions (68,74) may only be screwed in loosely.
Here the depth of penetration of the punch can be adjusted (compare. 3.2,i).
3.3
What should be done when die is blunt? A+B
a)
Undo screws (72).
b)
Exchange old die for new one.
c)
Check if air gap between punch and die is equal on both sides.
d)
Tighten screws.
3.4
What must be done if air gap is not uniform?
A+B
a)
Undo screws (72).
b)
Align die (70) according to punch (65) so that air gap between punch and die is equal on
both sides.
c)
Screw on die and check air gap.
3.5
How the wearing plate is to be changed?
A+B
a)
Unscrew die (70) and punch guide (71).
b)
Turn punch (65) to top dead centre.
c)
Take out wearing plate sideways.
d)
Insert new wearing plate (73).
e)
Turn punch to bottom dead centre.
f)
Fasten die and punch guide with screw, check air gap (see point 3.4) and tighten screw.
