More than.Since radio-frequency induction coil does not contact the danger so as to avoid short circuit, electric leakage with the tire inner mold of equipment tool, really reach
To energy conservation, securely and reliably；Shielding material makes will not being incuded by high frequency magnetic field for other non-heated target ferrimagnets generate heat.
According to actual needs, operator by the human-computer interaction interface of PLC control system set heating target temperature and
Heating time simultaneously generates temperature curve, the PLC main control chip temperature sensor internal automatically according to heater (i.e. heating chassis)
The variable of the temperature signal exported combines the temperature curve of setting to calculate instantaneous heating power and real-time delivery to digital intelligent
Energy high frequency induction power supply, instructs the real-time working power of each group radio-frequency induction coil and the current temperature of Real-time Feedback is controlled to PLC
System processed, temperature controlling range can be accurate to ± 1 DEG C.Also according to inside digital intelligent high frequency induction power supply temperature control module and
The signal of internal sensor feedback is, it can be achieved that the security functions such as dry combustion method protection, overcurrent protection, overheating protection.
Timing, temperature curve control can be realized by PLC control system 10, pass through 20 energy of digital intelligent high frequency induction power supply
Realize self-test, overcurrent protection, overheating protection.Induction heating can pass through temperature sensor according to the Current Temperatures of heated object
The temperature signal (analog signal) of feedback is managed through PLC main control chip, adjusts phase shift, arteries and veins by digital intelligent high frequency induction power supply 20
It rushes the parameters such as duty ratio and comes adjust automatically output power or frequency, realize heating temperature profile control.Feel since tire inner mold has
Should generate heat, power density it is big, thermal response is fast, i.e., plus i.e. heat, moment can reach required temperature, and be able to maintain the temperature of die surface
Degree is accurately controlled within ± 1 DEG C.
Digital intelligent high frequency induction power supply and PLC control system are programmed by sequencing and are utilized by human-computer interaction interface
Conversion of the circuit to input voltage and electric current, control output Current Voltage, and sensor is combined, realize the linkage control of circuit,
So that full-automatic accurate control may be implemented in heating process, device intelligence, manipulation safety and degree of power conservation are increased substantially.
In conclusion high-frequency induction heating chassis and the intelligent high frequency induction system of tyre vulcanization provided by the invention, change
Traditional heating method using steam heat radiation, heat transmitting is become, has been loaded using high-frequency electromagnetic induction and actively heated, than tradition
Heating method reduces the heat transfer process of multiple key, reduces the loss of energy, and tire inner mold tool is made to reach institute rapidly
It needs temperature and tire is heated, cooperate common completion tire with internal model under conditions of not changing original mechanism and process flow
Vulcanization.And intelligent control is realized using digital intelligent high frequency induction power supply and PLC control system, so that heating process can be with
Realize full-automatic accurate control, device intelligence, manipulation safety and degree of power conservation increase substantially；And the thermal efficiency and energy conservation
Effect is all obviously improved, and the quality of product is also greatly guaranteed.Heating process is without any exhaust gas useless solid discharge, the flames of anger, work
