板式箱型弯扭构件外形扁平,宽高比大于2,内部设置多道纵横向加劲肋,具有与矩形箱型弯扭构件不同的构造特征,因此其制作技术也不相同,本文对该类构件的成型原理、深化设计方法、制作工艺及测量方法进行了详细介绍.弯扭零件的展开方法是其详图设计时的一个关键内容,常见的方法有近似三角平面展开法、专业软件展开法和AUTOCAD专用模块展开法等,这些方法各有其特点.另外,弯扭零件成型过程中的回弹问题一直是该类构件制作中的一个关键问题,其回弹率与钢板的材质、厚度、宽度、下压量、压力及扭曲度等多种因素有关.文中介绍的研究成果已成功应用于大连国际会议中心的建设任务,对类似构件的制作具有较好的参考价值.
The box-type box-type torsion torsion member is flat in shape and has an aspect ratio of more than 2, and a plurality of longitudinal and transverse stiffeners are arranged in the interior, which have different structural features from those of the rectangular box-type torsion torsion member. Therefore, the manufacturing techniques thereof are also different. The forming principle, the deepening of the design method, the production process and the measurement method are introduced in detail.The bending and torsion parts expansion method is a key part of its detailed design, the common method is approximate triangle plane expansion method, professional software expansion method and AUTOCAD special module expansion method, each of these methods have their own characteristics.In addition, the bending process of springback parts forming process has been a key issue in the production of such components, the rebound rate and the plate material, thickness, width , The amount of depression, the pressure and the degree of distortion, etc. The research results presented in this paper have been successfully applied to the construction of Dalian International Convention Center and have good reference value for the production of similar components.
