Design And Research Of The Automatic Welding Machine Of Two Angle Steel Butt Into Square

Automatic welding technology can improve the welding quality and efficiency, reduce labor costs, and improve the working environment, so it has been widely used in the welding field. One company requires two angle steel butt into square, and the welding process is automatic. According to the requirements of the enterprise, this paper designs an automatic welding machine to realize two angle steel butt into square.First, according to the automatic welding technology agreement of two angle steel butt into square. The welding way, the welding method and the welding parameters are determined. This article uses the melting gas to protect the(MAG) welding craft extremely, and the welding torch walks.Next, according to the automatic welding technology agreement, an automatic welding machine of two angle steel butt into square is designed. Its essential organization includes: The welding shifts machine, the welding operation machine, sliding platform vehicle, the rotary driving device and the weld supporting institution and so on. Three-dimensional model of key parts are established by using modeling software. The corresponding part drawing and assembly drawing are draw by using two-dimensional software.Then, Transmission shaft, the essential spare part of the welding shifts machine, is analyzed by using the finite element analysis software. When motor starts, shaft the stress and strain values of the transmission shaft are obtained The safety factor of the shaft is calculated, and its strength is checked.Finally, the thermal energy coupling analysis is carried out on the butt welding process. The distribution of temperature field of the weld process is simulated under the different welding parameter by using the ANSYS programming language. With stress field analysis of the temperature field of body load, the distribution of the stress field under different welding parameters are obtained.
