Description
Technical field
The utility model is related to a kind of electrode transmission mechanism of tilting type induction furnace, belongs to metal smelt technical field.
Background technology
The forging type of tilt pouring is the main pouring type of alloy melting.Can casting mechanism can influence finally smooth
Molten metal is poured into ingot mould, the life-span of melting kettle can be also further influenceed, so alloy melting requirement tilt pouring mechanism behaviour
Make convenient and rotation reliability is high.
It is Hard link structure in existing tilt pouring mechanism, between water-cooled cable and the electrode of induction coil.Molten
In sweetening process research process, when operation tilt pouring mechanism is poured into a mould, the frequency converter overload-alarm of the motor that frequently verts,
Found by checking, flexural deformation has occurred in the interior electrode contact of electrode, and also there is loosening drainage external electrode joint.
After the applicant is analyzed it, it is believed that its reason is can not be right after supporting the crawler belt of water-cooled cable aging
In water-cooled cable servomechanism process provide effectively support, along between water-cooled cable and the electrode of inductor be Hard link structure,
Water-cooled cable can follow induction coil to move back and forth under motor effect of verting, so as to cause water-cooled cable outer with induction coil
Junction between electrode can produce the interior electrode contact for loosening leak and water-cooled cable significantly to deform.Due to tilt pouring machine
Structure uses the electrode wire leading method of coaxial configuration and uses interior circulation water system, and water-cooled cable will directly draw once leak
Play cooling capacity to decline, so as to be easy to burn induction coil.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided a kind of electricity of tilting type induction furnace
Pole transmission mechanism, water-cooled cable is fixedly connected and inner and outer electrodes is changed into the form of motor brush, so that no longer
Being rotated by inclining rotary mechanism is influenceed, and can effectively protect water cooling coaxial cable.
The technical solution adopted in the utility model is such：
A kind of electrode transmission mechanism of tilting type induction furnace, including water-cooled cable and its external electrode and interior electrode, also include
Vert motor and rear copper coin and preceding copper coin on insulator foot, and the interior electrode is by one piece of electrode connecting plate of conduction
It is fixed on preceding copper coin, electrode sequentially passes through rear copper coin and preceding copper coin in the induction coil, is fixedly mounted on the preceding copper coin
One graphite contact set is installed, the graphite contact set is socketed in induction coil on electrode in one copper fixed cover, copper fixed cover,
Fixedly mounted on the rear copper coin and a graphite contact set is installed in a copper fixed cover, copper fixed cover, graphite contact set set
It is connected on induction coil dispatch from foreign news agency polar ring, dead ring is installed in induction coil dispatch from foreign news agency polar ring, dead ring is socketed in electricity in induction coil
Extremely go up.
In above-mentioned technical proposal, the external electrode of water-cooled cable is fixedly mounted on rear copper coin and conductive by electrode connecting plate
It is fixedly mounted on preceding copper coin and conductive to sense to induction coil dispatch from foreign news agency polar ring, the interior electrode of water-cooled cable by electrode connecting plate
Electrode in coil is answered, so as to be converted into the conductive structure of motor brush form, when induction coil overturns, water-cooled cable will no longer
Influenceed by pitch motion, be tilting type sense so as to the phenomenon that junction loosens, deforms or occur leak occur never again
Stove is answered to provide effective safety guarantee.
After energization, induction coil can realize 0 ° -100 ° of upset under motor control of verting, and the intermediate frequency in induction coil is handed over
Time-dependent current produces magnetic field, and the metal in magnetic force line cutting crucible produces heat, and smelting metal is heated with this, then pours molten metal
Casting process is realized in the mould for entering lower section.
Because graphite has excellent electric conductivity, preferable intensity, dimensional stability can be kept in high temperature and is led
Conductance hot property, graphite contact set is used as contact conductive layer.And inclining rotary mechanism rotating speed is slow, rotational angle is 90 ° or so,
Therefore selection high purity graphite material makes graphite contact set just can meet service life.In view of graphite material resistance coefficient it is high,
Temperature rise, contact voltage is higher, and the loss of electric energy is larger, therefore the wall thickness of graphite cannula should not be too thick.
Preferably, on preceding copper coin and rear copper coin, in interference fit form between copper fixed cover and graphite contact set
Socket.Graphite contact covers and is not relatively rotated and copper fixed cover between, while in order to avoid copper fixed cover generation after power transmission
Expand and cause gap discharge, therefore use interference fit.
Preferably, on preceding copper coin, being socketed with gap fit form between electrode and graphite contact set in induction coil.
There is relative rotation in graphite contact set and induction coil between electrode, therefore taken full advantage of using gap cooperation between the two
The lubrication of graphite material, weares and teares small, and frictional heat is few.
Preferably, the connection end of the copper fixed cover is thread segment, the thread segment diameter is less than copper fixed cover main body
Diameter, it, to be threadedly coupled, facilitates the replacing of copper fixed cover with preceding copper coin or rear copper coin.Copper fixed cover covers to graphite contact and provides
Fixed and constraint.Under the control of the motor that verts, electrode, dead ring, induction coil dispatch from foreign news agency polar ring are with sensing in induction coil
Coil completes reciprocal flip-flop movement, and other parts are remained stationary.
Preferably, on preceding copper coin or rear copper coin, around the water-cooled copper of interior logical cooling water outside the copper fixed cover.
Because graphite contact set and copper fixed cover are the part in resonant tank, resonant tank current is 10 times of electric power loop electric current
Left and right, when temperature is more than 70 DEG C, contact resistance therebetween increases rapidly, therefore the hair that copper fixed cover and graphite contact cover
Heat is larger, and discharge accident is caused so as to cause contact gap to increase.Therefore, copper is welded to using square water-cooled copper to consolidate
Surely putting carries out water-cooling.
