【摘要】 本文基于企业的实际课题,目的是帮助企业独立完成实际设计项目,解决企业产品设计所面临的主要问题：(1)目前该产品的国内设计大多处于模仿国外同类产品阶段；(2)该产品目前只考虑生产因素,没有考虑用户的具体要求,所以产品不能够全面的满足用户的需求；(3)卷圆部分不能对成型管的直径进行调节,所以一台机器只能生产一种规格；本文正是基于以上问题考虑,运用系统分析设计方法—概念设计法对该产品作了全面设计。金属螺旋波纹管,特别是不锈钢制波纹管,能够自由伸缩、弯曲,具有洁净美观,防火耐腐,密封性能好,安装方便等优异性能,可广泛用于家用电器产品、船舶、工程机械,中央空调等设备中,是替代塑料软管和镀锌板制通风管的新型产品,可见金属螺旋波纹管已经得到了广泛地应用,设计适合国内消费者需求的金属螺旋波纹管成型机已经成了亟待解决的问题。本文的螺旋波纹管是经过两道工序,压合成型和咬口卷圆,为了完成这两项基本要求,本文运用概念设计来提出几种可行方案,并对几种可行性方案进行分析评价,得出最优方案。设计方面运用了Auto CAD和pro-e等设计软件对所设计的金属螺旋咬口机进行整体设计和三维数字化建模,利用pro-e进行运动学仿真,在不断地分析调整中得出最优方案,从而达到企业所规定的设计要求。更多还原

【Abstract】 Basing on the practical task, the paper’s purpose is to help the company complete the issue independently and solve the problem in the product designing, such as:(1)The domestic design of this product mostly locates in the stage of imitating similar products from abroad.(2)The product so far focuses on the factors of production without considering the user’s specific demand which can’t satisfy the requirement comprehensively.(3)The reel part can’t regulate the diameter of the pipe which causes one machine can just produce one type of the pipe. The paper put forward a newly method of systems analysis and design—conceptual designing method.Metal spiral corrugated pipe, especially stainless steel corrugated pipe, with the excellent performance of free expansion and bending, clean appearance, fireproofing, rotproofness, good seal ability and easy installation,which can be widely used in household electric appliances, ships, engineering machinery and central air-conditioning equipment, is a new widely used product replacing the plastic hose and galvanized vent pipe. So, the metal spiral corrugated pipe’s design for domestic using has become a problem. The designing of spiral corrugated pipe has two processes, pressing molding and bite roll round, in order to complete the two basic requirements, this paper presents some feasible design concept, compares several feasible scheme, obtain the optimal scheme. The whole design using design software such as Auto CAD and pro-e to form 3D model, adopting pro-e for motion simulation, obtain the optimal scheme through constantly analysis and adjustment, so as to achieve the enterprise ’s design requirements.更多还原
