Abstract

This article designed an automated production lines of the C-shaped steel’s specical welding equipment.The purpose is to improve the welding quality and productivity,also to reduce labor costs and labor intensity. On the premise of understanding the structure and working principle of the welding equipment’s loading or unloading and school-shaped bodies, This design has completed the overall scheme design.Production lines is pied into four pars,which are loading and unloading system,transport system,fid system and school-shaped bodies.Then combined with the welding parameters,I completed the loading and unloading’s mechanical design, analyzed the institutions ,working principle, the relevant size parameters,and checked the key components ,which Conform to the structural characteristics of the C-shaped steel and vertical welding mode. Then combined with the analysis of the deformation of the workpiece during the welding process, I completed the design of the school-shaped bodies,which meet with the vertical welding mode of the C-shaped steel. Finally, combined the optimization objectives of the welding equipment,I optimized the key components of the loading or unloading bodies and school shaped bodies. In addition, This design used pro/e software to design the virtual prototype,which included feature modeling of the part and virtual assembly of the institutions to make it easy for readers to understand the structure and principle of the design.
