摘　　要：针对风力发电机组预应力墩基础工程设计施工中对整装式大尺寸金属波纹筒产品的需求,为对应的可移动式波纹筒自动生产线配套设计了一种新型整装式大尺寸波纹筒成型装置。分析了波纹筒成型装置的工作原理和主要功能,设计了波纹板成型和卷筒成型装置等关键核心部件;研究并设计复杂异性截面波纹板冷弯成型、筒体自动螺旋拼接压制成型等关键技术工艺;分析了成型装置在波纹筒生产试验中出现的波纹板成型时阻力过大、用于锁边的波形出现起皱现象、用于锁边的波形外形尺寸不一致、卷筒成型时波纹筒出现偏心、锁边成型后有干涉现象等主要技术和生产工艺问题,提出了处理方案并解决了试生产中的问题。研制的样机投入工程现场生产试验,验证结果表明所设计的装置达到了设计性能指标要求。The self-contained king-size corrugated metal pipe is necessary for the foundation engineering design and construction of the prestress pier of wind driven generators.To match the automatic production line of mobile corrugated pipes which serves for on-site production,a new forming unit for self-contained king-size corrugated metal pipes is designed.First,the operating principles and main functions of the forming unit of corrugated pipes are analyzed,and the critical components including the forming parts of corrugated plates and rollers are designed.Besides,the following core techniques are put forward,such as the cold roll forming of corrugated pipes with complex and special sections,and the automatic spiraling,splicing and pressing of the pipe.Then,the following problems of the forming unit encountered in the corrugated pipe pilot production are analyzed and corresponding solutions are proposed:excessive resistance occurs during the forming of corrugated pipes;the seaming part of the corrugated pipe wrinkles;the seaming parts have different shapes and dimensions;the corrugated pipe has a degree of eccentricity during the roll forming;Interference phenomenon occurs after the seaming of the corrugated pipe.Finally,the prototype of the forming unit is verified through the on-site production test and all the performance indices meet the designing requirements.
