    穿孔頂頭輾軋段錐角的計(jì)算及合理設(shè)計(jì)

    CALCULATION AND RATIONAL DESIGN OF PIERCING PLUG ROLLING TAPER

    • 摘要: 根據(jù)穿孔時(shí)軋輥的布置特點(diǎn),導(dǎo)出了空間變形區(qū)模型條件下的穿孔頂頭輾軋段錐角的計(jì)算公式,比較了不同送進(jìn)角時(shí)按照目前所采用的三種計(jì)算方法所計(jì)算的穿孔頂頭輾乳段錐角的差異,給出了合理確定穿孔頂頭輾軋段錐角的頂頭位置參數(shù)。

       

      Abstract: Bascd on the roll arrangement for piercing, the calculation formula for piercing plug rolling taper is deduced with a space deformation-zone model, Calculated with the three current calculation methods, different tapers due to different feeding angles are given, also the plug position parameters ensuring a rational taper.
