不銹鋼管件的旋壓工藝
發布時間:2019-04-15  瀏覽:
   隨著旋壓技術的發展,旋壓工藝逐步代替傳統工藝來生產不銹鋼管件。西方發達國家就此項技術對我國采取技術封鎖。因此,我們的研究目標是實現對不銹鋼管件的極限減薄旋壓,將不銹鋼管件直徑增大到800mm。并且研制生產相應規格管件的強力旋壓設備,實現大直徑不銹鋼管件生產技術的國產化。

    不銹鋼管件主要用于航空航天和兵器工業,而金屬旋壓工藝最重要的一個優點是能制作整體無縫的回轉體空心件,根本消除了與焊縫有關的不連續性、強度降低、脆裂和拉應力集中等弊端?;谝陨狭δ軈?,設計了強力旋壓機的本體結構。著重對旋壓機的旋輪座部件結構進行了方案比較并確定最終方案;對軸向進給系統和徑向進給系統進行了設計;對主軸部件結構的傳動部件進行運動學分析;對新設計的卸料裝置進行了具體介紹。最后,采用有限元軟件ABAQUS對旋壓機的機身和活動橫梁進行了強度、剛度分析,針對設計不合理的地方提出了改進措施。
