style="text-indent:25px">封頭毛坯是如何制作的？1.封頭毛坯尺寸(計算公式)：P=1.2(PN+δ+2h)。2.劃下料線時,先劃十字中心線,再劃坯料線及人孔開孔線,人孔之長短軸要與十字中心線重合且長軸必須與鋼板軋制方向垂直(軋制方向通常為鋼板長度方向)。3.下料時,封頭毛坯外圓可用手工切割，易采用定心切割,推薦采用仿形切割。4.封頭毛坯的拼接：封頭毛坯應(yīng)盡量采用整塊鋼板制成。若需拼接時,允許由兩塊鋼板按GB/T25198-2010標(biāo)準(zhǔn)和GB/T25198-2010標(biāo)準(zhǔn)、施工圖樣進行。焊接后，內(nèi)表面拼接焊縫以及影響成形質(zhì)量的外表面拼接焊縫,在成形前應(yīng)將焊縫余高打磨至與母材齊平,鏟平長度為離圓坯外邊緣300～350mm。5.當(dāng)壓制有孔封頭時，中間開的小孔應(yīng)光滑平整，鋸齒形的氣割邊緣應(yīng)修磨光滑，以免壓孔翻邊時出現(xiàn)開裂現(xiàn)象。6.毛坯必須按〈規(guī)定〉進行材質(zhì)標(biāo)記移植,標(biāo)記必須清晰正確。加熱爐周圍的障礙物必須清理,加熱爐內(nèi)的雜物應(yīng)清理,裝爐前,應(yīng)把坯料上的雜物清理干凈。檢查送料工具,保證運轉(zhuǎn)正常，安全裝爐。封頭長期使用后變化小、磨損的燒損小。</p><div

style="text-indent:25px">封頭是石油化工、原子能到食品制藥諸多行業(yè)壓力容器設(shè)備中不可缺少的重要部件。1、封頭是壓力容器上的端蓋，是壓力容器的一個主要承壓部件。所起的作用是密封作用。一是做成了罐形壓力容器的上下底，二是管道到頭了，不準(zhǔn)備再向前延伸了，那就用一個封頭在把管子用焊接的形式密封住。和封頭的作用差不多的的產(chǎn)品有盲板和管帽，不過那兩種產(chǎn)品是可以拆卸的。而封頭焊好了之后是不可以再拆卸的。與之配套的管件有壓力容器、管道、法蘭盤、彎頭等產(chǎn)品。2、封頭的品質(zhì)直接關(guān)系到壓力容器的長期安全可靠運行。封頭一般是采用厚板沖壓成形，由于材料在成形過程中各部分的應(yīng)力應(yīng)變狀態(tài)不同。浙江干燥設(shè)備封頭制造廠</p><p style="text-indent:25px">封頭的功能是非常強大的，適用于多種場合。浙江干燥設(shè)備封頭制造廠</p><p style="text-indent:25px">現(xiàn)在，封頭廠的我就來跟大家講一講封頭加工需要注意的一些要點吧！首先，封頭一般是采用厚板沖壓成形，由于材料在成形過程中各部分的應(yīng)力應(yīng)變狀態(tài)不同，使得沖壓成形后的封頭各部分的壁厚也不相同，因此，封頭成形不能忽視壁厚變化。影響封頭壁厚變化的主要因素有成形材料的力學(xué)性能、變形程度以及沖壓模具結(jié)構(gòu)。材料強度越低，壁厚減薄量越大；變形程度越大以及模具間隙和凹模圓角越小，則壁厚減薄量越大；模具潤滑狀況不佳，減薄量增大。其次，封頭沖壓成形模具間隙不能過小。在封頭拉深成形過程中，其直邊急劇增厚，尤其是直邊長度在lOOmm以上時，增厚更為嚴(yán)重，其增厚率可達10%以上。因此封頭成形模具間隙不能過小，應(yīng)大于料厚的10%，否則，材料無法通過模具間隙，工件底部嚴(yán)重變薄甚至拉破，但模具間隙過大、凹模圓角過大，將降低壓邊效果，又會在封頭上部產(chǎn)生褶皺。因此，封頭沖壓成形模具的間隙要合理選擇。末尾，瓜瓣類厚板成形不能忽視冷校形。瓜瓣類厚板零件，一般采用熱沖壓成形。由于熱壓收縮率難以控制，故在設(shè)計模具時一般不予考慮，而是在成形后進行冷校形，以保證其形狀和尺寸的精度要求，所以瓜瓣類厚板成形不能忽視冷校形。浙江干燥設(shè)備封頭制造廠</p><p
