Minigraf M3
2. MACHINE DESCRIPTION
2.1
WORKING PRINCIPLE
The benchtop Frame Assembling Machine Minigraf 3 has
been realized to assemble any kind of frame.
The Minigraf 3 being of simple construction and extremely
easy to use, makes it possible to join with absolute precision
any kind of moulding by means of special steel V-nails.
It uses v-nails with the “pulling power” effect in different
sizes.
2.2
MAIN COMPONENTS
The main components constituting the machine are:
Pneumatic clamping device to allow a proper locking of the
mouldings to insert several V-nails in different positions
Magnetic pressure pads of several types, at quick
replacement, to have the proper clamping of any profile
Dual function foot pedal for the separate control of the
clamping and nail insertion
Pneumatic opening of the V-nail magazine for a very quick
reloading
Nail heads sizes 7, 10 and 15 mm.
2.3
MACHINE STRUCTURE
The movement directions during the machine’s working are
the following:
-
X AXIS
Movement of the horizontal clamp
-
Y AXIS
Movement of vertical clamp
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.
2.4
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 permitted temperatures
go from 5° to 40° C, with a humidity level 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 and has to
guarantee a clear visibility and can not 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 are not
representative of 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
building, etc…). Furthermore the allowed exposure levels
could change according to several 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.
