Minigraf 4
2.2
MAIN COMPONENTS
The main components of the machine are:
-
Frontal clamping device to have perfect junctions.
-
Adjustable tilting fences.
-
Magnetic pressure pads of several types to provide the
proper clamping of any profile
-
Soft moulding clamp device that adjusts the pressure
during the several working phases.
-
Dual function foot pedal for separate control of clamping
and nail insertion
-
Pneumatic opening of the V-nail magazine for very
quick reloading
-
Nail heads sizes 7, 10 and 15 mm.

DIMENSIONS
The overall dimensions are reported on table 2.9-A
2.5
SURROUNDING CONDITIONS
The machine does not need special surrounding conditions.
It has to be installed inside an industrial building, lit, aired
and with a compact and flat floor. The admitted temperatures
go from 5° to 40° C, with an humidity not higher than 50%
at 40° C or 90% at 20° C.
2.6
LIGHTING
Premises lighting must be conformed to the norms in force
in that Country where the machine is installed. It has to
guarantee clear visibility and can’t create dangerous light
reflections.
2.7
VIBRATIONS
In standard conditions conformed to the indication of
machine proper utilization, the vibrations do not create
dangerous conditions
.
The average quadratic weighed level,
according to the acceleration frequency to which arms are
exposed does not exceed 2,5 m/s2.
2.8
NOISE EMISSIONS
The machine is designed and projected for reducing the
noise emission level to its source. In standard working
conditions the Machine noise power level is:
Acoustic Continuous Equivalent weighed
pression A
<70dB
Acoustic Istantaneous weighed
pression
<130dB
The noise levels indicated are emission levels and do not
represent operating levels. In spite of an existing
relationship between emission levels and exposure ones,
this can not be used in a reliable way to define if further
precautions are necessary. The factors determining the
exposure level to which the working force is subjected,
include exposure length, working premises characteristics
and other noise sources (number of machines, closed area,
etc…). Furthermore the allowed exposure levels could
change according to several different Countries. At any
rate, the information provided, will allow the Machine
Operator to achieve a better evaluation of the danger and
risks they are submitted to.
The indicated noise levels are emission
ones measured in standard conditions of
use. In case of any machine modification,
the above mentioned levels could be
changed and should be tested on the same
machine.

WORKING PRINCIPLE
The frame assembling machine Minigraf 4 has been realized
for the production of medium or large sized frames.
The machine is equipped with a V-nail driver mounted on
a movable carriage which can be pneumatically controlled
by the operator.
The frame assembling machine Minigraf 4 can use special
“Pulling Power” V-nails which draw the corners very tight
together.
