空彎是通過(guò)外輥與管坯外壁的單向接觸形成彎矩使帶料彎折，空彎會(huì)使彎折線產(chǎn)生壓縮，壓縮效應(yīng)使彎折線縱向伸長(zhǎng)，彎折處金屬出現(xiàn)堆積變厚，這就是空彎的壓縮/增厚效應(yīng)。 </p> <p> （1)空彎的優(yōu)點(diǎn)是可以在無(wú)法進(jìn)行實(shí)彎時(shí)進(jìn)行邊長(zhǎng)的彎折，比如方矩管的上邊/側(cè)邊同步彎折和精整?？諒澾€可以彎折R<0.2t的內(nèi)角而不致管壁發(fā)生斷裂。 </p> <p> （2)空彎的缺點(diǎn)是享鑫方矩管在上邊/側(cè)邊同步空彎時(shí)，由于上輥和下輥同時(shí)產(chǎn)生壓力，成型力容易超越臨界點(diǎn)，造成邊部失穩(wěn)內(nèi)凹，并且也會(huì)影響到機(jī)組穩(wěn)定運(yùn)行和成型質(zhì)量，貴州鍍鋅矩管型號(hào)規(guī)格表，貴州鍍鋅矩管型號(hào)規(guī)格表，貴州鍍鋅矩管型號(hào)規(guī)格表。這也是方矩管和圓管空彎成型時(shí)不同的特點(diǎn)。專業(yè)供應(yīng)無(wú)縫矩管，他家價(jià)格低廉！快咨詢。貴州鍍鋅矩管型號(hào)規(guī)格表</p><div

1.計(jì)算壓應(yīng)力，就是豎向壓力作用在方矩形鋼管的橫截面上所產(chǎn)生的壓應(yīng)力。這個(gè)比較簡(jiǎn)單，就是壓力（單位N）除以方矩形鋼管橫截面面積（單位m平方）。只要壓應(yīng)力小于材料的許用應(yīng)力即可。 </p> <p> 2.方矩形鋼管受壓，要計(jì)算穩(wěn)定性。穩(wěn)定性的計(jì)算較為復(fù)雜。要看連接的方式是兩端固接還是一端固接另一端鉸接。估計(jì)你不只使用1跟立柱，所以可以簡(jiǎn)單計(jì)算成兩端固接。臨界壓力簡(jiǎn)單計(jì)算：P=(4*n*Pi^2*E*I)/[(L/2)^2]。n立柱的數(shù)量，pi^2就是拍的2次方，E彈性模量，I慣性矩，L立柱長(zhǎng)度。
