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(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(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(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。封頭整體的結(jié)構(gòu)不是很復(fù)雜，所以維護(hù)起來是比較方便的。江蘇拱形封頭生產(chǎn)廠家直銷</p><p
