Device for inductively removing the tion from
wires and/or profiles
The present invention concerns a device for and a method of
inductively ing insulation from wires and/or profiles.
For example in wiring a synchronous generator in a wind power
installation and at other locations in a wind power installation the electric
components have to be connected together for example by electric cables.
That is often effected by a bundle of tors consisting of a licity
of electric wires which each have an insulating lacquer layer being used.
The insulating layer or the lacquer layer then has to be removed at the
ends of the wires so that an electric or galvanic connection can be made to
the respective electric components. Hitherto stripping the insulation at the
ends of the wires or profiles is effected mechanically.
As l state of the art attention is ed to DE 1 064 580 B,
DE 10 2008 043 876 A1 and DE 601 28 389 T2.
Therefore an object of the present invention is to provide a device for
and a method of stripping insulation of wires and/or profiles, which permit
rapid stripping of insulation with a uniform y.
That object is attained by a device for inductively stripping insulation
from wires according to claim 1 and by a method of inductively stripping
insulation from wires according to claim 6.
Thus there is provided a device for stripping insulation from wires
and/or profiles having a lacquer or plastic coating. The device has a
receiving portion for receiving the ends of the wires and/or profiles from
which insulation is to be stripped, at least one induction coil in the region of
the ing portion for inductively generating heat to vaporise or
thermally remove the g on the wires or profiles within the receiving
portion and at least one suction removal hose connected to the receiving
portion for sucking away the vaporised or thermally removed coatings of
the wires and/or profiles in the region of the receiving portion.
The coatings on the wires and/or profiles can be vaporised or
thermally removed with the device accordingto the invention and sucked
away by the suction removal hose. Thatmakes it possible to quickly and
easily strip insulation from the wires in an automatic procedure.
In addition in an aspect of the ion there is provided a
compressed air hose which feeds compressed air into the receiving portion
for cooling the heated wire ends and for removing the residues of the
coating in the region of the receiving ‘portionLSurface tensions are
produced by the compressed air at a corresponding re and the
heated ends are cooled. In addition at the same time the residues of the
coating in the region of the receiving portion can be simultaneously blown
away and disposed of through a suction removal hose.
In a r aspect of the present invention a further portion ls
arranged around the outside wall of the receiving portion so that a hollow
chamber is d between the outside wall of the receiving portion and
the portion. In that case the compressed air is urged or blown through that
hollow chamber and through holes in the outside wall of the receiving
portion. The ssed air and any particles and gases t can then
be sucked away by way of the suction removal hose.
The invention also ns a method of stripping insulation from
wires‘ and/or profiles with coatings. The ends of the wires and/or profiles to
be ed are introduced into a receiving portion. Inductive generation of
heat is implemented in the region of the receiving portion by means of at
least one induction coil to vaporise or thermally remove the insulations or
coatings on the wires and/or profiles. The vaporised coatings of the wires in
the region of the receiving portion are sucked away by a suction l
hose.
The present invention also concerns a device for stripping insulation
from wires and/or profiles with a lacquer or plastic coating. The device has
3O a receiving portion for receiving the ends of the wires and/or es to be
stripped of insulation. The device further has at least one induction coil in
the region of the receiving portion for inductively generating heat to
se or thermally remove the coating of the wires and/or profiles within
the receiving portion. The device r has a suction removal hose
connected to the receiving portion for sucking aWay the vaporised or
thermally removed g of the wires and/or profiles in the region of the
receiving portion. The device further has a compressed air hose for feeding
compressed air into the receiving portion for g the heated ends of the
wires- and/or profiles and for removing residues of the coatings in the
region of the receiving portion. The device further has an outside wall of
the receiving portion and a portion arranged therearound, a hollow
chamber being provided between the portion and the outside wall. The
compressed air hose opens into the hollow chamber. Provided in the
outside wall of the receiving portion are holes through which the
compressed air can flow out of the compressed air hose. The device further
has reduction units Which can be introduced into the receiving n to
reduce the inside er of the ing n. '
The ion concerns the notion of provided a device for
inductively stripping insulation from wires and/or profiles, wherein the ends
of the wires, from which insulation is to be stripped, are introduced into the
device and heat is generated inductively (that is to say the copper of the
lines is ively heated) so that the coatings on the wires are vaporised
and the gases or vapours are sucked away. Then or parallel thereto
compressed air can be used for cooling the ed ends of the wires and
for better releasing and removing residues on the surface. According to the
invention the device for stripping insulation from wires and/or profiles can
be used in the area of a wind power installation.
Further configurations of the invention are subject—matter of the
appendant claims.
Advantages and embodiments by way of example of the invention
are described more fully hereinafter with reference to the drawing.

serve to receive the feed cable. The or coil 20 is preferably water-
cooled. The induction coil can be screwed to a hand portion. The induction
coil can be of different sizes in dependence on the wire cross—section.
The length of the introduction portion 20 can be variable so that the
length of the region of the wires, that is to be stripped of insulation, is also
adjustable. In addition a reduction unit can be introduced into the
introduction portion 20. The reduction unit can be for example in the form
of a hollow cylinder, wherein provided in the hollow cylinder are openings
or bores corresponding to openings or bores 4 in the tube 7. That reduction
unit can be d to be replaceable. The thickness of the wall of the

thicknesses can also be processed in the device for, stripping insulation from
3O wires.
Figure 2 shows a mmatic partial view in section of the device
for stripping insulation from wires according to the first embodiment. The
device has an (inside) tube 7, two half—shell portions 6, a (water-cooled)
induction coil 10 and a receiving portion 20 for receiving the ends of the
wires that are to be stripped of insulation. The device further has a first
hose 1 for sucking away fumes, Combustion residues and s which
occur in the operation of inductively stripping insulation frOmthe wires. The
device r has a secondhose 2 serving to feed compressed
air into the
receiving portion 20. The ssed air can be fed into a hollow chamber
3 between the half-shell portion 6 and the tube 7 by
way of openings 2a at
the end of the second hose (compressed air hose) 2. The compressed
can pass from the hollow chamber 3 by way of openings 4 in the tube
into the ing portion 20.

A bundle of wires which are to be stripped of insulation is introduced
into the receiving portion 20 within the tube 7. The length of the ing
portion 20 or the depth of penetration of the end of the wires, that is to be
stripped of insulation, is adjustable. Inductive heat is generated within the
receiving portiOn 20 by means of the induction coil 10 so that the
insulations on the wires or the insulating lacquer can melt or burn away
and vaporise within that portion, that is to say the lacquer or gs on
the wires is thermally removed. The vaporised or thermally removed
insulating material can be sucked away by way of the hose 1. After the
insulation has been stripped off by vaporisation or thermal removal
of the
insulating material compressed air can be introduced into the hollow
chamber 3 by means of the second hose 2 and the openings 2a, the
compressed air then passing through the openings 4 in the tube in the
receiving portion 20 and cooling the heated ends of the wires. The
compressed air can then in turn be sucked away by
way of the first hose 1
and can suck away les of the insulating
material.
The device according to the invention for ing insulation from.
wires can provide a simple, quick and inexpensive possible
way of stripping
insulation from wires. The insulation stripping operation can be effected
automatically and with uniform quality. The wires or profiles to be stripped
of insulation can be used for example in wiring of a synchronous generator,
for example for a wind power installation. Alternatively the device for
stripping insulation‘from wires and/or profiles can also be used for stripping
tion from electric wires or electric profiles in the area of a wind power
installation.
While in the state of the art the insulation stripping ions had
be effected mechanically the insulation on the wires according to the
invention is vaporised or detached by inductive heat (that is to say
thermally removed) and the vaporised or thermally removed les of
the insulations can be suckedaway. Compressed air

The induction coil 10 according to the ion produces a magnetic
field which can heat the copper in the bundle to 800 to 900 degrees
so that
the coating is vaporised or thermally removed.
The time for the heating operation, the suction removal of fumes
vaporised particles and also the cooling operation can be ed
automatically or in partly automated fashion with the device ing to
the ion for stripping insulation from wires.
Subjecting the ends of the wires that are to be stripped of insulation
to compressed air is not only advantageous for g
purposes but as a
result the residues of the insulation or the lacquer es
are also blown

The heating s can. last for e between 5 and
7 seconds,
the blowing operation can last between 15 and 20 seconds. Sucking air
away through the first suction removal hose 1 is preferably always
3O activated so that no toxic vapours can
escape.
In an aspect of the invention there
can be prOvided a sealing cap for
sealing off the opening of the receiving portion when the ends that are to
be stripped of insulation are introduced.

insulation can be set for example in a region of 30 mm to 70 mm (for
example with Setting spacings of 5 mm). A sensor for detecting an
introduced wire can be provided in the region of the receiving portion 20.
Optionally the coil may be activated only after ion of an uced
wire so that it is possible to avoid activation of the coil when a wire is not
introduced. The device can allyvalso have a display unit for displaying
whether the wires are or are not introduced.
The insulation stripping ion (activation of the induction coil)
can be effected manually by actuation of a key or automatically when the
wires to be stripped of insulation have been uced into the receiving
portion.
3O The wires used should have an insulating material or an insulating
lacquer or layer which have a vaporlsation temperature ntially lower
than the g temperature of the wires used.
The device for stripping “insulation from wires and/or profiles
according to the first embodiment can also be used for inductively heating
cable ends, on to which a cable shoe is to be squeezed. The inductively
heated cable end and the cable shoe can then be soldered in the region of
the inductively heated wire end of the cable shoe; The device according
the second embodiment can in that case substantially correspond to the
device of the first embodiment so that the cable end to be heated is
introduced with the cable shoe fixed thereon into the introduction portion
, the induction coil is activated and thus heats the copper in the cable
ends. To e the fixing of the cable shoe to the wire ends
a soldering
operation can be effected, wherein the wire end is heated or warmed up in
such a way that the heat is sufficient to melt the soldering tin so that the
sOldering tin can flow into the inside region of the cable shoe and thus an
improved fixing action can be ed.
In a third embodiment which can be based on the first or second
embodiment the device has two introduction units each having
a respective
induction coil, wherein the first introduction n serves to strip the
insulation from the wires or profiles and the second introduction portion
serves to heat the cable ends to solder a cable shoe to the cable end. As in
the first or second embodiment compressed air can be used to cool the
soldered wire or profile ends. In addition the fumes produced in the
soldering operation (like the thermally removed coatings) can be sucked
away through the above-described hose 1.
