摘要薄壁不锈钢管是我国近年发展起来的高档次新颖建筑材料,应用广泛,同时以卡压式连接为主的施工工艺也得到广泛应用。卡压式连接顾名思义就是采用外力把管材与管件卡压变形，然后靠内部的橡胶圈来起到密封作用，从而使连接部位不漏水。设计主要结合现有的设计理念，在符合设计要求的前提下，设计时不锈钢管的卡压装置机架整体上主要采用了钢板焊接闭式结构，这种结构制造方便无需大型加工设备，并且，选材主要使用了45号钢等常用材料，使用钢板焊接的加工工艺，因而，生产工艺性较好，一般机械厂均能制造。设计中主要使用了CAD、Pro/E等工程制图软件，使用了Pro/E软件进行三维仿真。49496

Abstract Thin-walled stainless steel tube is a novel construction materials in China in recent years developed high-grade，Wide range of applications，Pressure connected to the card-based construction technology has also been widely.The entrapment connection definition is the use of external force to the pipe and pipe fittings compression deformation, and then rely on the internal rubber ring to play a role in sealing, so that the joints watertight.Designed primarily with the existing design concept, under the premise that meet the design requirements, design stainless steel tube compression device on the rack as a whole, the main steel plate welded closed structure, this structure and the convenience of no large-scale processing equipment andthe selection is mainly used 45 steel and other commonly used materials, the use of steel welding processes, and therefore, the production technology is better, the general machinery plant can manufacture. The design is mainly used in engineering graphics software such as CAD,Pro/E ,Pro/E software for 3D simulation.
