style="font-size:20px;">三通管件是近代工業(yè)上應(yīng)用量大、面廣的一種常見的管道聯(lián)接件,在輸送中、高壓液體或氣體的過程中會有局部渦流出現(xiàn),對管件的性能有較大的影響。過去采用傳統(tǒng)制造方法生產(chǎn)三通管件存在較多嚴(yán)重缺點(diǎn),所以現(xiàn)在多采用優(yōu)質(zhì)無縫鋼管成形三通管。</span></p> <p align="left"> <span style="font-size:20px;">內(nèi)高壓工藝和翻邊工藝生產(chǎn)無縫三通管件。 對于內(nèi)高壓工藝,首先運(yùn)用DYNAFORM軟件進(jìn)行模擬,分析研究了工藝參數(shù)(內(nèi)壓,軸向進(jìn)給力和徑向背壓力)的加載路徑對三通管內(nèi)高壓成形的影響,通過研究發(fā)現(xiàn):(1)足夠的進(jìn)給量是獲得一定支管高度的必要條件,但是進(jìn)給量過大的話,會造成壁厚的嚴(yán)重增加;(2)內(nèi)壓和背壓力的影響方式相反,內(nèi)壓過大或背壓力過小都會造成支管頂部過度減薄甚至是破裂,相反的話,支管高度太小,背壓力阻礙了主管的生長。</span></p> <p align="left"> <span style="font-size:20px;">對不同尺寸的三通管內(nèi)高壓工藝參數(shù)的匹配關(guān)系進(jìn)行了預(yù)測和優(yōu)化,可以成形出較好質(zhì)量的三通管?，F(xiàn)有的企業(yè)生產(chǎn)大口徑三通管要通過多道次翻邊工藝,稱為多級翻邊擴(kuò)孔工藝。冷擠<a href="http://">三通機(jī)</a>的管件機(jī)械系列生產(chǎn)效率高，生產(chǎn)出來的三通管件外形美觀，質(zhì)量標(biāo)準(zhǔn)多為達(dá)標(biāo)。</span></p> <div id="5pnvjhp" class="float_c news-page fs_14"> <div id="vp5l7fr" class="f_l">
