Description
Technical field
The utility model relates to the control circuit of electric welding machine, especially about the improved control circuit of a kind of steel cord bonding machine.
Background technology
The control circuit system of electric welding machine is an important component part of electric welding machine work, and the Circuits System of existing electric welding machine is controlled through circuit and to be changed output voltage values when the control secondary voltage, thereby reaches best welding purpose.But; Existing control circuit system mainly is that the fixedly winding through transformer obtains several fixing output voltages; And regulate these several fixing voltages of control by hand switch and export, for example, the control circuit of existing electric welding machine is 6 fixing output voltages being regulated welding machine by 6 gear switch; As everyone knows, fixing voltage output is difficult to realize satisfied welding effect for welding under unlike material, the condition.In practical operation,, and be prone to cause poor welding quality and be welded into the low shortcoming of power often because of fixing shifting switch is difficult to regulate suitable voltage output accurately.Especially when welding the product of monofilament, steel cord, the welding machine of existing level regulation voltage is operating difficulties, the product poor welding quality of voltage-regulation not only, and the productivity ratio of operation is lower.
The utility model content
The purpose of the utility model is defective and the deficiency that exists in the existing welding of electric welding machine to monofilament, steel cord for overcoming, and on the basis of existing electric welding machine structure, its control circuit is carried out the improvement of step-less adjustment output voltage.For realizing this purpose; The technical scheme that adopts is: the improved control circuit of a kind of steel cord bonding machine; Comprise power supply, transformer, power circuit breaker; It is characterized in that in the loop of power circuit breaker and transformer, being connected variable-frequency governor, Programmable Logic Controller, simulation solid-state relay respectively, Programmable Logic Controller expansion back connects the simulation solid-state relay, and the output of simulation solid-state relay connects the electric hammer contactor; The shunt that variable-frequency governor connects transformer is connected with regulating relay and module relay, the output link block relay of simulation solid-state relay.
Press the electric welding machine that this programme is implemented, utilize the output characteristics of variable-frequency governor to come the control transformer primary voltage, realize the stepless modulation of secondary voltage.Programmable Logic Controller can be worked out action, specification, voltage, time, tempering voltage, tempering time, a burning voltage, polishing time, electric hammer voltage supervisor that welding is used the time through computer in advance; And pass back to Programmable Logic Controller, control and regulate job parameter by it.The utility model has not only been realized accurately stable stepless voltage regulation of electric welding machine, and the relevant operating parameter of storage operation easily, helps improving welding quality and productivity ratio, is a kind of useful improvement design.
Description of drawings
Fig. 1 is the control circuit sketch map of a kind of embodiment of the utility model;
Fig. 2 is the control circuit block diagram of a kind of embodiment of the utility model.
The specific embodiment
Further specify with regard to this embodiment in conjunction with accompanying drawing.This embodiment is connected variable-frequency governor (selecting S1100-2T1-5G for use) 1, Programmable Logic Controller (selecting VBO-20MT for use) 2, simulation solid-state relay (selecting SSR-25LAH for use) 3 respectively in the loop of power circuit breaker K1 and transformer 5; Programmable Logic Controller 2 expansion backs connect simulation solid-state relay 3; 3 outputs of simulation solid-state relay connect electric hammer contactor J1; The shunt that variable-frequency governor 1 connects transformer 5 is connected with regulating relay R1 and module relay R 2, the output link block relay R 2 of simulation solid-state relay 3.Wherein, Variable-frequency governor is the vitals of The whole control circuit, and variable-frequency governor is through the characteristic of its individual event output, the primary voltage of control transformer; Reach the stepless control of secondary voltage; It is exactly to change the speed that voltage instantaneous produces that variable-frequency governor also has a characteristic, and the voltage generation time is short during owing to welding, needed voltage and the requirement of time when helping reaching to welding.Action, welding specification, weldingvoltage, weld interval, tempering voltage, tempering time, a burning voltage, polishing time, electric hammer voltage supervisor that Programmable Logic Controller can the time be used welding; Upload to Programmable Logic Controller after working out in advance through computer, control, regulate parameter by it again.The simulation solid-state relay is to regulate two parts that burn a voltage and regulation voltage through Programmable Logic Controller to form.Dc source 4 is parts that the AC power of each device of confession changes dc source into.
