Development And Application On Flexible Manufacture Cell Of Group Welding Tools For End Wall Of Railway Freight Wagon

Among the products of many varieties of the freight wagons, wagon end wall structure is different. The past, use a rigid welding equipment, replacement of a species need to be replaced or adjusted in a set of welding equipment, there is preparation cycle is too long, and equipment utilization is low, the problem of higher production costs. Through the topics, the aim is to adapt to many varieties, small batch, fast-paced changes in the market demand to achieve rapid conversions between different models, reducing manufacturing costs, to achieve flexible goals of welding equipment to the freight wagons end wall, and for freight welding large parts flexible process equipment used to provide theoretical and practical guidance.The topic of flexible welding systems for the automotive, marine, engineering machinery, etc. widely used and its application in freight wagons manufacturing industry behind the status quo, compared to the freight wagons end wall structure family of products and production processes, analysis of the current welding system performance features and technical difficulties, the flexible welding equipment, the possibility of a study, while the flexible side wall of the economic benefits of welding units were analyzed. First of all, using modern design methods, right-side wall, welding equipment, the functionality of decomposition, developed a flexible welding equipment, design, then layout and structural design; Secondly, the use of group technology principles and Modular design theory to study the flexible welding equipment, a number of key technologies, in-depth analysis of flexible process equipment configuration and combination of their component modules, structural features, made of flexible welding cell structure of the program and to carry out the Flexible and standardized design.Through the research projects, broke through the end wall of flexible welding equipment, a number of key technologies, innovative manufacturing process developed a end wall, end wall facing the process of group and the end wall of welders bit flexible welding unit designed and implemented into a group of technology, information technology and mechanical and electrical integration, modular realization of serialization, standardization, modularity. Practical application and comprehensive evaluation shows that end wall of flexible welding unit according to the products change needs to quickly reconstruct, reliable performance, shorten production preparation cycle of freight wagons, reduce duplication of manufacturing processes and equipment to prepare the workload, improve productivity and reduce manufacturing costs. The technology has reached domestic leading level in the same industry.
