For above-mentioned purpose, the utility model provides a kind of curved tempering to become the control system of arc, it comprises: become arc motor, frequency converter, contactor and PLC controller, wherein: described frequency converter couples mutually by described contactor and a power supply, described frequency converter connects described PLC controller and described change arc motor, described PLC controller is issued described frequency converter speed and torque signals, make the described change arc of described transducer drive motor, described change arc motor is used for that curved tempering is become arc and controls.
In the better embodiment, described PLC controller and described frequency converter carry out Profibus DP communication.
In the better embodiment, also comprise an isolating switch, it is connected with described contactor and described power supply, for the protection of described frequency converter.
In the better embodiment, also comprise an electromotor brake, it links to each other with described frequency converter, is used for described motor is braked.
In the better embodiment, also comprise a reactor, an end of described reactor connects described contactor, and the described other end that carries out reactor connects described frequency converter.
Compared with prior art, thereby the utility model reaches the execution of steady constant speed by the repeatedly switching of two kinds of patterns, and physical construction has been protected in the cooperation of Negotiation speed and moment, has realized even running.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not paying the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, become the composition of the control system block diagram of arc for a kind of curved tempering of the utility model, the control system 1 that curved tempering of the present utility model becomes arc comprises: become arc motor 11, frequency converter 12, contactor 13 and PLC controller 14, wherein: described frequency converter 12 couples mutually by described contactor 13 and a power supply 15, make described contactor 13 adhesives by an outer button, described power supply 15 is used for described frequency converter 12 power supplies, described frequency converter 13 connects described PLC controller 14 and described change arc motor 11, described PLC controller 14 carries out Profibus DP communication with frequency converter 13, issue described frequency converter 12 speed and torque signals by the Control on Communication word, make described frequency converter 13 drive described change arc motor 11, described change arc motor 11 is used for that curved tempering is become arc and controls, the control of PLC controller 14 also has a feedback signal (being the X7317 and 4314 on Fig. 4) simultaneously to frequency converter 13, when frequency converter 13 reaches threshold when becoming arc, frequency converter 13 inner output relay actions, the normal closed conducting of making war, thereby frequency converter 13 feedback signals are turned back to 14 inputs of PLC controller, cease and desist order thereby PLC controller 14 sends frequency converter 13.
As shown in Figure 2, control system one embodiment that becomes arc for a kind of curved tempering of the utility model forms schematic diagram, and the utility model also comprises an isolating switch 16, and it links to each other with described contactor 13 with described power supply 15, is used for frequency converter 12 is protected.
As shown in Figure 3, another embodiment of control system that becomes arc for a kind of curved tempering of the utility model forms schematic diagram, and the utility model also comprises an electromotor brake 17, and it links to each other with described frequency converter 12, is used for described change arc motor 11 is braked.Also comprise a reactor 18, a described end that carries out reactor 18 is connected with described contactor 13, and the described other end that carries out reactor 18 connects described frequency converter 12, is used for described frequency converter 12 is protected.
As shown in Figure 4, become the control system one embodiment circuit diagram of arc for a kind of curved tempering of the utility model, as shown in the figure, described PLC controller 14 selects S7 300PLC, described frequency converter 12 to select SIEMENS G120 frequency converter, described isolating switch 16 to select QF0402, described contactor 13 to select KM2105, electromotor brake 17 to select DCT0402 and described reactor 18 to select FT0402 in the present embodiment.Its concrete principle of work is as follows:
