摘　　要：随着铁路货车行业高速、重载的设计需求,减少车体钢结构焊接量已经是发展趋势。车体钢结构部分的地板、侧板等关键金属板材制件趋于少拼接和无拼接设计。长大金属板材制件的下料方案和质量控制已经成为铁路货车制造企业的关注焦点。对出口澳大利亚力拓40t轴重力拓矿石车地板长边取直工艺进行研究,通过设计金属板材长边冲剪模具,可以实现地板长边取直制件质量和生产效率的提升。With the design requirements of high speed and heavy load in railway freight wagon industry,reduced the welding quantity of body steel structure has been the trend of development.The floor and side sheet metal parts and other key parts of the car body steel structure is developing in the direction of less splicing and no splicing design.Feeding scheme and quality control of long metal plate parts has become the focus of the railway freight wagon manufacturing enterprises.Reaserch on the floor long edge straight process of Rio Tinto 40t axis gravity extension ore vehicle exported to Australia,through the design of sheet metal punching die could improve the quality and production efficiency of the long side of the floor.
