DEFORM￠402mm5052铝管挤压工艺设计+文献综述 随着科学技术的不断进步和现代化经济的高速发展，铝合金型材正向着大型化和整体化、薄壁扁宽化、尺寸高精度化、形状复杂化、外形轮廓美观化的方向发展。品种规格不断增多，应用范围不断拓展，已由20世纪50、60年代民用建筑型材为主体，扩展到了航天航空、汽车船舶、交通运输、电力电子、石油化工、机械制造、家用电器等各行各业和人们日常生活各个方面。近年来，大型铝合金型材的发展尤其引人注目，为了适应这种市场需求趋势，各国都在加速建设重型挤压机或大型型材挤压生产线。 据不完全统计，目前每年全世界大型铝合金型材的用量大约在30万吨以上，规格品种达5000种以上。对大型铝型材进行科学的分类，有利于合理地选择生产工艺和设备，正确地设计与制造工模具，迅速地处理挤压车间的生产技术问题和管理问题。按照用途或使用特性，大型铝合金型材可分为通用型材和专用型材。除条形、T字形、工字形、槽形等几种常见的通用型材外，绝大多数为专用型材。 5052铝管用途主要用于要求高的可塑性和良好的焊接性，在液体或气体介质中工作的低载荷零件，如邮箱，汽油或润滑油导管，各种液体容器和其他用深拉制作的小负荷零件：线材用来做铆钉。也常用于交通车辆、船舶的钣金件，仪表、街灯支架与铆钉、五金制品、电器外壳等。随着使用部门对产品的精度、形状、表面光洁度等各种质量指标提出了新的要求，面向用户保证供应符合各种质量要求的轻合金产品，采用挤压加工技术生产比其它压力加工方法（如轧制、锻造等）有更大的优越性和可靠性。 According to incomplete statistics , at present the world each year a large amount of aluminum profiles of approximately 30 million metric tons, more than 5,000 varieties of specifications . For large aluminum scientific classification , was conducive to rational selection of production technology and equipment , proper design and manufacture of tooling and rapid processing extrusion plant production technology and management issues . In accordance with the purpose or use of properties, large aluminum materials can be pided into general profiles and special profiles . In addition to bars , T -shaped , -shaped , grooved , such as several common generic profiles , the vast majority of special profiles . 5052 aluminum Mainly used for high plasticity and good weldability , in a liquid or gaseous medium, low work load parts, such as mailboxes, gasoline or oil ducts, containers and other types of liquids produced by deep drawing of the small load parts: wire used to make rivets. Also commonly used in transport vehicles, vessels, sheet metal parts, instruments , lights bracket and rivets, metal products, electrical appliances , such as Shell . With the use of the accuracy of the product pision , shape, surface finish , and other quality indicators put forward new requirements, a variety of user-oriented quality assura
