    JCO成型寬模不重疊折彎技術(shù)

    Wide-die/Non-overlap Bending Technique for JCO Forming Process

    • 摘要: 介紹一種不預(yù)彎、免擴(kuò)徑的JCO寬模不重疊折彎技術(shù)。該技術(shù)通過(guò)采用寬模和大步長(zhǎng)，實(shí)現(xiàn)了直縫埋弧焊管的不重疊折彎成型。分析認(rèn)為：足夠的折彎力和滿(mǎn)足管筒弧形設(shè)計(jì)要求的上模半徑R，是實(shí)現(xiàn)寬模不重疊折彎的兩個(gè)重要條件；采用上模半徑R滿(mǎn)足管筒弧形設(shè)計(jì)要求的模具，通過(guò)調(diào)整下模開(kāi)口距離和上模下壓量，實(shí)現(xiàn)寬模不重疊折彎，是提高管筒成型質(zhì)量和效率的有效措施。

       

      Abstract: Elaborated here in the essay is a wide-die/non-overlap technique for JCO forming that is free of prebending and expanding,The said technique has brought about the formation of the LSAW pipe without subjecting to the overlap bending operation step owing to adopting the wide-die and the large stride length as well.The analysis result leads to such a conclusion that both sufficient bending force and the radius R of the upper die that meets the design requirement for the curvature of the cylindrical blank tube act as the two critical preconditions for pipe formation with the wide-die/non-overlap bending process.Quality of blank tube formation and the manufacture efficiency shall be improved by means of such measures as using die with the upper part’s radius R meeting the design requirement for the cylindrical blank tube,and adjusting the opening distance of the lower die,and the screwdown amount of the upper die so as to obtain the purpose of wide-die/non-overlap bending.
