    Visualization Solution and Data Analysis of Skew Rolling Pass Parameters

    • 摘要: 詳細(xì)介紹了一種基于三維CAD設(shè)計軟件的斜軋孔型參數(shù)的可視化求解方法，并以桶形輥穿孔機(jī)、錐形輥穿孔機(jī)和斜軋擴(kuò)管機(jī)3種斜軋機(jī)型為例，介紹了孔型開度值、軋輥與軋件接觸點(diǎn)處的速度矢量的求解步驟和求解過程，以及計算結(jié)果的驗(yàn)證方法；采用大量數(shù)據(jù)分析討論了實(shí)際生產(chǎn)中軋機(jī)調(diào)整、軋輥返修對孔型開度值的影響。認(rèn)為可視化求解法適用于所有斜軋機(jī)型的孔型參數(shù)分析，可為工具的設(shè)計提供更加準(zhǔn)確的數(shù)據(jù)支持。

       

      Abstract: Elaborated in the paper is a three-dimensional CAD-based visualization solution for skew rolling pass parameters.Taking the three types of skew rolling mills(barrel type piercer, cone type piercer and rotary expanding mill)as examples, the solving steps and processes which are related to roll gap values, and velocity vector of the contact point between roll and workpiece are described.Also described is the verification method for the calculation result.Based on massive data, effects by rolling mill adjustment and reworked roll on pass gap value are analyzed and discussed.It is concluded that the visualization solution method is suitable for pass parameter analyses of different types of skew-rolling mills, and is capable of providing more accurate data to support design of the operational tools.
