PLC in girth welding device applications


Machine and started welding two specified damper girth welding is completed, automatically open the screen door,franklin and marshall, manually remove the shock absorber system to complete a holding operation 1: pieces of period, restored to its original position.

The components of the work under the control of the PLC, and its working principle shown in Figure 3. Walk 3 Footswitch gun pneumatic operating principle in the control process, PLC according to external signals given by the set time control solenoid valves, operating equipment and welding equipment parts, so as to achieve into the gun, the gun back, open, closed, operation of the workpiece,fitch abercrombie, welding and other working conditions. PLC control of the plane is divided into two kinds of manual and automatic. PLC based on manual input conditions when the decision of the valve working condition; automatic status, PLC according to the external switch state to complete the task requires 4PLC hardware control section. Han Yi PLC hardware control in part by the PLC (OMRON production),franklin marshall milano, input and output signals. Input from a variety of buttons, proximity switches, photoelectric coupler etc.; output signal from the solenoid valve, relay,abercrombie paris, and various status indicators, of which all limit switches are close to completion, PLC external wiring diagram in Figure 4. 5PLC some ridicule software system program design is based on the logical flow chart to design the vertical ∞ &]} I ∞ house moss ≥ v! good a king] Ju Lin Hou Zhiyong and other research and design: PLC in girth welding device in the application of section 8 A period piece running gun KB gun K2T automatic welding instruction manual instructions instructions instructions starting place instructions to close the gun back into the gun to open IJCOM/-X0-YOX1. . . . . . . . . . . . / --C0M2YIX2---/--COM3x3 Suck Y2X4Y3X5-once Y4X6 --- / a Y5X7--/-----/--Y6X8--/--Y7X9x10----x children ---- - District One Y8x12 mine Y9xI3 a X [4Y10x15YIIX16 Figure 4PLC module external wiring diagram using internationally accepted language to implement the trapezoidal ring. There are a wealth of PLC timers,ed hardy tøj, counters and interrupt subroutine, calls and other logic functions. In the device software, the spindle running in the use of optical coupling grating chip count signal acquisition time, by counting the rings to complete the cycle of welding or seam welding section. In order to weld the weld appearance, with a lone post-op closing arc features in the software design with a call to the specified subroutine to complete this process. This will be introduced this part of software design. Read out from the ladder program execution SBSO0 delay TIM002 first action, the internal relay is energized, welder to work (starting with 0.5s of the small current arc process). While the motor input signal 01002 was electric, operation, optical grating coupler by sampling the input signal 00000, start counting. Counter CNT006 set different parameters of the cycle of girth welding or soldering section to improve the accuracy of the welding arc, the weld seam is more in line with requirements. When the arc welder when received. Once again to perform SBSO0 subroutine calls SBN00 action f0.5s complete collection of small current arc welding). This small current before and after the second use of welding, weld the natural beauty and reliable. Ladder shown in Figure 5. 6 Conclusion girth welding wide range of applications, especially in the car's shock absorber,ed hardy suomessa, wheel,ralph lauren skjorter, motorcycle muffler, and tricycles and other ring parts can be used to complete the girth welding automatic welding, the use of PLC control of girth welding device functional, reliable, simple and convenient. After a long period of use, PLC control girth safe and reliable hardware and software devices, thereby increasing the girth welding of the level of automation. References: [1] Jian-Qiang Wu.
