Automobile Vehicle Bridge Welding Equipment Of Axle Tube And Transitional Flange For PLC Control And Welding Procedure

Along with the rapid development of automobile,the automobile bridge is increasingly demanded highly quality and reliable welding.Reliable welding quality,high degree of automation of welding equipment sedans cars of car manufacturers become palanquin developments in the field of welding trend.PLC technology with the development of computers and microelectronics technology has formed an automatic control technology.It has entered a mature stage,and will be towarded large-scale, high-speed,high-performance direction.Foreign manufacturers have already had a number of production lines of PLC products.PLC had been widely used in metallurgy,chemical, machinery manufacturing,and other industrial sectors in the mid-1980s in our country,.This paper is mainly devoted to the current number of the car rear axle,which is low automatic welding equipment,the low level of accuracy,and high efficiency is not the issue.Through deeply analysis of CO₂ automatic welder,a girth welding automation equipment of the car rear axle based on PLC autocontrol technology is developed.By PLC controlling gun movement,the welding process automation is realized.Through Siemens S7-200 Series PLC hardware and software research and analysis,the welding process PLC control welding procedures is designed.CO₂ girth welding production lines of the car rear axle is achieved real-time control.And circuit diagram is drawn,the appropriate components are chosen,the appropriate welding process is formulated,appropriate welding parameters are confirmed.System Operation show that welder has features of high accuracy,security and smart response speed,high automation,and achieve purposes of lower labor intensity,improving welding quality and production efficiency,lowed scrap rates,convenient operation,easy maintenance,in particular to improve the working conditions of workers and improve production efficiency has obvious practical significancePLC control technology is used to control the bridge girth welding production process, which the production line overcomed the traditional logic control susceptible to environmental interference,short life expectancy,the high failure rate and maintenance difficulties,and other defects,improved the economic efficiency.When the welding process change,the only change control procedures can meet better performance.Through the design of the hardware and software protection link greatly enhancing the bridge girth CO₂ gas welding production line job stability,reliability and adaptability,economy and the resistance of all kinds of interference,which will have a high prospect of the market.
