The present embodiment provides a kind of rubber support vulcanization plants, as shown in Figure 1 comprising die ontology 10 and medium-high frequency electricity
Source 20, medium-high frequency power supply are the power supplys for referring to output 8k-30kHz current signal.The die ontology 10 include upper mold 11, in
Mould 12 and lower die 13, the middle mould 12 have the hollow structure for being suitable for placing rubber support, the setting position of middle 12 inner wall of mould
Holding tank is offered, the channel opening that accommodates is arranged towards the inside of the middle mould and around its inner wall one week；11 He of upper mold
The lower die 13 is respectively arranged at two ports of the middle mould 12 and closely connect with the middle mould 12.In the holding tank
Inside is fixedly installed magnetic conductive groove 2, and magnetic conductive groove 2 is prepared by magnetic conduction ceramic material, and the opening of the magnetic conductive groove 2 is described in
The inside of middle mould 12 is arranged；It further include conducting wire 4, disk, which is set to inside the magnetic conductive groove 2, forms at least one hot-wire coil 3, and two
End is electrically connected after the magnetic conductive groove 2 and the middle mould 12 with medium-high frequency power supply 20；The medium-high frequency power supply 20 includes first
Sub- power supply, the first sub- power supply input the first high-frequency current signal so that the formation pair of the hot-wire coil 3 to the conducting wire 4
The first electromagnetic field that steel plate edge is heated；The magnetic conductive groove 2 and the hot-wire coil 3 are completely covered adhesive layer 5,
The inner wall of surface and the middle mould 12 forms smooth mould inner surface.
The figure of first electromagnetic field is as shown in Fig. 2, since hot-wire coil 3 is arranged in 7 outer circumference direction of steel plate
, therefore after it is acted on steel plate 7, direction of an electric field is along steel plate circumferencial direction, and magnetic direction is to put down perpendicular to where steel plate 7
The direction in face.The distribution situation of the magnetic line of force and electric field line is schematically depicted in figure.First electromagnetic field effect is on steel plate 7
Afterwards, the steel plate edge at 3 position of hot-wire coil can be heated quickly, and the width at the edge probably has 10mm or so.Due to
Steel plate 7 is metal material, if after its edge is rapidly heated, by the heat transfer of metal, center also can be faster
It is heated.
In above scheme, it is powered by being arranged inside die ontology by magnetic conductive groove prepared by magnetic conduction ceramic material to accommodate
Coil, hot-wire coil and external medium-high frequency power electric connection, to obtain high-frequency current to generate the first electromagnetic field to steel plate

The third high-frequency current signal and the first high-frequency current signal have a difference on the frequency, first electromagnetic field with it is described
The superposition of third electromagnetic field is evenly heated different steel plates with realizing.Because of third electromagnetic field and the first electromagnetic field width having the same
Degree and phase only have certain difference on the frequency.As shown in figure 4, after therefore third electromagnetic field is superimposed with the first electromagnetic field, energy
The position of electromagnetic field wave crest is enough adjusted, namely the position of Bmax is enabled to be changed between different layers steel plate 7.
In specific implementation, medium-high frequency power supply 20 can determine its output power and output electric current in real time, according to output work
Rate and output electric current can determine the impedance for the hot-wire coil 3 connecting with the medium-high frequency power supply 20, because of the resistance of hot-wire coil
It is anti-related with the temperature field in space where it, so can conclude that hot-wire coil by way of determining hot-wire coil impedance in real time
Thermo parameters method situation inside corresponding middle mould can determine same layer steel plate not according to the thermo parameters method situation
Temperature conditions, the temperature conditions of different layers steel plate with position, thus can determine the second electromagnetic field and the first electromagnetic field it
Between phase difference how should adjust, also can determine how third electromagnetic field and the difference on the frequency of the first electromagnetic field should adjust.
That is, the medium-high frequency power supply 20 can determine the magnetic reactance of hot-wire coil, root according to output power and output electric current
The temperature field of steel plate is determined according to the magnetic reactance；According to the temperature field adjust second electromagnetic field and first electromagnetic field it
Between phase difference.Inside the processor of the medium-high frequency power supply, a temperature can be stored in advance and adjust threshold value, i.e. each layer of steel
Plate, temperature difference between steel plate edge and steel plate center (such as set no more than the adjusting threshold value and adjust threshold value and take the photograph as 70
Family name's degree), when the temperature difference between steel plate edge and steel plate center is smaller, can control between the second electromagnetic field and the first electromagnetic field
Phase difference it is smaller, predominantly steel plate edge is heated.When steel plate edge and the temperature difference at steel plate center are Celsius close to 70
When spending, increase the phase difference of the second electromagnetic field and the first electromagnetic field, main execution quickening heat is from steel plate edge into steel plate
The operation of heart transition.
In addition, the medium-high frequency power supply 20 determines the magnetic reactance of hot-wire coil according to output power and output electric current, according to institute
State the temperature field that magnetic reactance determines steel plate；It is adjusted between the third electromagnetic field and first electromagnetic field according to the temperature field
Difference on the frequency.That is, determining that the temperature of which layer steel plate is lower according to the distribution situation in temperature field, then adjusting at electromagnetic field peak value
Reach its temperature as early as possible with other layer of steel plate in this layer of steel plate position to improve the heating speed to this layer of steel plate
Balance.
