【摘要】 扁挤压筒是挤压大型、扁宽、薄壁、复杂空心和实心型材必不可少的重要工具，也是大型扁宽薄壁型材生产的关 键技术之一。扁挤压筒的设计和制造属高新技术范畴，在我国尚属空白，国外也在研制之中。在充分分析世界各国的有 关资料之后，结合我国的具体情况，利用我国现有的８０ＭＮ挤压机上的Φ６５０ｍｍ圆挤压筒的外套和中套，对扁挤压筒 内套的结构设计、材料选择、强度计算以及加工制造工艺和装配工艺进行了系统的研究，改装成了６７０ｍｍ×２７０ｍｍ ×１６００ｍｍ扁挤压筒，经试挤获得了良好的效果，为我国研制扁挤压筒积累了经验。更多还原

【Abstract】 Flat container is the most imporant tool for extruding big, wide, thin-wall, comples and hollow profiles, and also is one key processes of producing big, wide and thin-walled extruded profiles. Now this technology is still on trial and test all over the world. This article analyses the current situation of our country and systematically researches the design, material selection, strengty calculation, manufacture and assemble processed. Use the internal and outer coats of the existting Φ650 mm round container in extrusion press and refit it into a 670 mm × 270 mm × l600 mm flat container. The result of test extrusion is good, providing many value experience for the development of flat container in China.更多还原
