style="text-indent:25px">如何防止球形封頭變形？球形封頭中，根據(jù)壓機(jī)立柱間距和壓模尺寸及鋼板尺寸，選定頂圓需拼焊的板寬和拼焊塊數(shù)。盡可能采用壓鼓。直徑7.5m球形封頂圓取直徑6.2m，3塊板拼焊后壓鼓，然后車環(huán)縫坡口；直徑6.5m球形封頭頂圓取直徑5.36m，2塊板拼焊后壓鼓，然后車環(huán)縫坡口。直徑12m球形封頭頂圓取直徑lOm，直徑較大，由5塊板拼接，先分別壓形，然后切割研配向心、徑向縱縫坡口。為了防止自由變形，先制2個(gè)圓胎，檢測(cè)研配都可在此胎上進(jìn)行。球形封頭是以球殼的球冠部分所形成的封頭，有半球形封頭和無(wú)折邊球性封頭兩類。它在同樣容積下表面積較小，相同承壓條件下需要的厚度較薄，從節(jié)省材料和強(qiáng)度上看，是較合理的。另外，球形封頭具有鍛打精良，表面光滑，耐酸耐堿耐高溫，外形美觀，質(zhì)感性能強(qiáng)等特點(diǎn)。此類封頭為一塊深度比較淺的球面體(球冠)。其結(jié)構(gòu)見(jiàn)圖。它結(jié)構(gòu)簡(jiǎn)單，深度淺，易加_百一制造，成本低。但它與筒體連接處存在著明顯的形狀突變，導(dǎo)致產(chǎn)生比較高的局部應(yīng)力，故受力狀況極差，所以這類封頭一般只能用于直徑比較小，壓力較低的容器。</p><p style="text-indent:25px">現(xiàn)在，封頭廠的我就來(lái)跟大家講一講封頭加工需要注意的一些要點(diǎn)吧！首先，封頭一般是采用厚板沖壓成形，由于材料在成形過(guò)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(qiáng)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(rùn)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(guò)小。在封頭拉深成形過(guò)程中，其直邊急劇增厚，尤其是直邊長(zhǎng)度在lOOmm以上時(shí)，增厚更為嚴(yán)重，其增厚率可達(dá)10%以上。因此封頭成形模具間隙不能過(guò)小，應(yīng)大于料厚的10%，否則，材料無(wú)法通過(guò)模具間隙，工件底部嚴(yán)重變薄甚至拉破，但模具間隙過(guò)大、凹模圓角過(guò)大，將降低壓邊效果，又會(huì)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(jì)模具時(shí)一般不予考慮，而是在成形后進(jìn)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。封頭部分遇到轉(zhuǎn)動(dòng)封頭卡死，無(wú)反饋力時(shí)，可將潤(rùn)滑油加入部分轉(zhuǎn)動(dòng)表面處理。</p><div
