    薄壁鋼管成型鼓包解決方法淺析

    Initial Discussion Concerning Solution of Bulging Phenomenon Occurring in Light-wall Steel Tube Formation Process

    • 摘要: 薄壁鋼管在各行業(yè)中的應(yīng)用非常廣泛。在生產(chǎn)薄壁鋼管時(shí)遇到的一個(gè)共性問(wèn)題是成型鼓包。引起鼓包最根本的原因是帶鋼邊緣延伸超出了該材料的彈性極限范圍。從變形原理入手,分析了產(chǎn)生鼓包的原因,著重從原料、工藝布局和軋輥孔型設(shè)計(jì)等方面提出了解決鼓包的一些方法。

       

      Abstract: Light-wall steel tubes are widely used in many fields.A common problem as encountered with in manufacturing of such tubes is bulging of the material during formation process.The root cause of this undesirable phenomenon is that the extension of the strip edge area is out of the elasticity limit of the material.In the paper the cause for the said bulging is analyzed with the deformation theory.Also proposed are certain solutions for the problem,involving the material,process arrangement and roll groove design,etc.
