The utility model introduces the programmable controller (PLC) to perform the program logic control in the control ling circuit of the machine, and the self-protection function and the control function through analyzing. The utility model has the advantages that the automation degree is high, the operation is simple; various movement control is accurate, the control precision is high, and the control precision of the welding time parameter reaches 0.01s; therefore, the timing precision and the operation reliability of the copper aluminum tube to the butt welding machine is greatly enhanced, and when the welding material specification is replaced, the former reliable welding parameter is only required to be adjusted out, the massive debugging is omitted, the material is saved and the time is saved, and the production cost is reduced.
Description
Technical field:
The utility model relates to a kind of welding equipment, particularly a kind of copper aluminum pipe butt welding machine.
Background technology:
The performance of copper aluminum pipe butt welding machine in the market can not satisfy well large-scale production the stability condition that must satisfy, former control system adopts time relay control welding parameter, because performance indications such as control accuracy, stability, reliability are lower, after the work a period of time of being everlasting, welding effect changes, even substandard products appear, must readjust welding parameter.Particularly when product specification changes, a large amount of test welds need be carried out, just optimal parameter can be found out.Both waste a large amount of copper aluminum pipe raw material, increased the adjustment time again, thereby caused production cost to increase.
Summary of the invention:
The purpose of this utility model is the deficiency that exists in the above-mentioned technology; a kind of new copper aluminum pipe butt welding machine is provided; the utility model is introduced programmable controller (PLC) and is carried out programmed logic control in the control circuit of this machine; and, worked out the relevant PLC control program by analyzing self-protection function and control function.This machine automaticity height, simple to operate; Each moves precise control, the control accuracy height, and weld interval, the parameter control accuracy reached 0.001s; Convenient and swift and the real-time demonstration of parameter adjustment weld interval; Through the many index check, product qualification rate reaching is more than 99%.Thereby improved the timing accuracy and the functional reliability of copper aluminum pipe butt welding machine greatly, and when changing the welding material specification, only need access welding parameter reliably both can, remove a large amount of debugging from, material-saving saves time, and has reduced production cost.
The purpose of this utility model is achieved in that and comprises IGCT, circuits for triggering plate, PLC Programmable Logic Controller, electrode, welding coil is characterized in that the welding coil is connected with IGCT, IGCT is connected with the circuits for triggering plate, and the circuits for triggering plate is connected with the PLC Programmable Logic Controller.The adjusting of copper Al pipe butt welding electric current is carried out AC voltage adjusting by two IGCT reverse parallel connections and is realized.Welding process is controlled by Programmable Logic Controller PLC.When copper pipe with after aluminum pipe contacts, PLC sends enabled instruction for the circuits for triggering plate, the circuits for triggering buttress sends pulse according to current setting value, makes the IGCT conducting, begins welding.When the travel switch closure, the expression copper pipe advances and puts in place, and PLC sends cut-offing instruction for the circuits for triggering plate, thereby makes the IGCT closure, and welding finishes.
The utility model has the advantages that, the automaticity height, simple to operate; Each moves precise control, the control accuracy height, and weld interval, the parameter control accuracy reached 0.001s; Convenient and swift and the real-time demonstration of parameter adjustment weld interval; Through the many index check, product qualification rate reaching is more than 99%.Thereby improved the timing accuracy and the functional reliability of copper aluminum pipe butt welding machine greatly, and when changing the welding material specification, only need access welding parameter reliably both can, remove a large amount of debugging from, material-saving saves time, and has reduced production cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a fundamental diagram of the present utility model
Fig. 3 is a working plan of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing present embodiment is described further
As shown in Figure 1, copper Al pipe butt welding electric current is regulated and to be carried out AC voltage adjusting by two IGCT reverse parallel connections and realize.Welding process is controlled by Programmable Logic Controller PLC.When copper pipe with after aluminum pipe contacts, PLC sends enabled instruction for the circuits for triggering plate, the circuits for triggering buttress sends pulse according to current setting value, makes the IGCT conducting, begins welding.When the travel switch closure, the expression copper pipe advances and puts in place, and PLC sends cut-offing instruction for the circuits for triggering plate, thereby makes the IGCT closure, and welding finishes.
As shown in Figure 2, aluminum pipe, copper pipe place left and right two anchor clamps appropriate locations respectively, and promptly aluminum pipe right-hand member, copper pipe left end and after spacer contacts slightly start working cycles.This is a sequence logical control works fine system with 6 states.
(1) send electricity separately to magnetic valve PQ1, compressed air enters two clamping cylinders through PQ1.The piston of two cylinders moves downward simultaneously and compresses the copper aluminum pipe respectively.Meanwhile compressed air also enters positioning cylinder through PQ1, makes the spacer withdrawal, welds ready.
(2) continue to send electricity to magnetic valve PQ1, keep the impaction state of copper aluminum pipe; PQ2 send electricity to magnetic valve, and compressed air enters propulsion cylinder through PQ2, makes it promote the laterally inserted aluminum pipe of copper pipe.
(3) PQ1, PQ2 are continued energising, the moment behind copper pipe contact aluminum pipe is connected welding circuit.The copper aluminum pipe begins welding process, and this moment, copper pipe continued to insert to aluminum pipe.
(4) copper pipe is welding in the propelling of aluminum pipe.When propelling puts in place, cut off welding current, propulsion cylinder stops to advance, but clamping cylinder still compresses the copper aluminum pipe, and keeps a period of time.
(5) magnetic valve PQ1 outage, the clamping cylinder homing is put, and spacer stretches out and ejects the copper aluminum pipe that welds, and simultaneously, next group copper aluminum pipe is positioned.
(6) magnetic valve PQ2 outage, propulsion cylinder is return.
As shown in Figure 3, the course of work is start back standby, with the foot-operated programmable switch that starts, compresses the copper aluminum pipe, advances copper pipe, the energising welding, and the outage cooling is unclamped the copper aluminum pipe and is return original position, shutdown.As then standby of continuous welding, repeat workflow.
