等离子填丝-注射设备的控制系统设计
|
摘要
根据等离子填丝-注射制备复合板材的工艺特点,设计了以DVP-40EH00T3型可编程逻辑控制器(PLC)为控制核心,以DOP-B07SS411型触摸屏为人机接口的等离子填丝-注射控制系统,阐述了等离子填丝-注射设备组成、控制系统的硬件设计和控制系统的运动设计。研究结果表明:等离子双枪试验中,填不锈钢焊丝,并分别注射B_4C、WC、镍包石墨粉末、镍包MoS_2,制备的复合板材基本成形。显著消除了焊道搭接,且双枪制备的两个区域接头熔合良好,证明了等离子填丝-注射设备的PLC控制系统是稳定可靠的,满足工艺需求。
The control system of plasma filler wire-injection equipment was designed and developed according to the technological characteristics of composite plate producing process. The control system used programmable logic controller( PLC) of DVP-40EH00T3 as the control core,and used touch screen of DOP-B07SS411 as human-computer interface. The plasma filler wire-injection equipment composition,hardware design and motion design of the control system were expounded. The results show that the composite plates,prepared by filling stainless steel welding wire and injecting B_4C,WC,nickel-coated MoS_2 and nickel-coated graphite powder respectively during two plasma torches test,are basically formed. The weld bead lap is significantly eliminated,and two regions of the joints prepared by two plasma torches fuse well. It is proved that the design of PLC control system of plasma filler wire-injection equipment is reliable and meets the process requirements.
