鈑金(jin)折彎是(shi)大多數零件成型中的(de)關鍵工(gong)序，折彎質量直(zhi)接關系到產品的(de)終形(xing)狀和特性。

影響鈑(ban)(ban)金折彎(wan)(wan)精(jing)度(du)的(de)因(yin)素很多，如配件的(de)尺寸(cun)精(jing)度(du)、模(mo)具采(cai)用的(de)合理(li)性和折彎(wan)(wan)順序等，因(yin)此，鈑(ban)(ban)金折彎(wan)(wan)精(jing)度(du)的(de)探索必須從這些因(yin)素一(yi)一(yi)分析，以及如何控制它(ta)。折彎(wan)(wan)質量可以實現折彎(wan)(wan)質量的(de)。

1.鈑金展開尺寸計算

（1）配(pei)件彎(wan)曲半(ban)徑的(de)(de)(de)設計(ji) 材料(liao)彎(wan)曲時(shi)(shi)，圓(yuan)角區域的(de)(de)(de)表層被拉(la)伸，內層減少。在鋼板(ban)折彎(wan)厚度不變的(de)(de)(de)情況(kuang)下(xia)，彎(wan)曲圓(yuan)角越低，山(shan)西管料(liao)卷(juan)圓(yuan)加工，材料(liao)的(de)(de)(de)拉(la)壓比就(jiu)越大。當表面圓(yuan)角的(de)(de)(de)拉(la)應力(li)超(chao)過材料(liao)的(de)(de)(de)極限強(qiang)度時(shi)(shi)，就(jiu)會出(chu)現裂紋(wen)或斷(duan)裂。彎(wan)曲部(bu)分(fen)的(de)(de)(de)結構設計(ji)應避免彎(wan)曲圓(yuan)角半(ban)徑過小。

彎曲部(bu)分的小彎曲半徑與材料(liao)的力學(xue)性能、表(biao)層質量、硬(ying)化程度和(he)纖維的取向有關。只有在產品設計時才選擇小彎曲圓(yuan)角半徑。通(tong)常，彎曲圓(yuan)角等于(yu)或略低于(yu)板材的厚度。

鋼(gang)板(ban)(ban)切(qie)(qie)割(ge)(ge)加(jia)工(gong)(gong)(gong)時關(guan)鍵用到的(de)方法是(shi)火苗切(qie)(qie)割(ge)(ge)、水切(qie)(qie)割(ge)(ge)及其等離(li)子切(qie)(qie)割(ge)(ge)。在工(gong)(gong)(gong)業(ye)生產中，打多數公司都是(shi)整塊鋼(gang)板(ban)(ban)選購(gou)，隨后自(zi)主切(qie)(qie)割(ge)(ge)成所需的(de)款式，但(dan)繁雜的(de)鋼(gang)板(ban)(ban)切(qie)(qie)割(ge)(ge)工(gong)(gong)(gong)藝需要的(de)切(qie)(qie)割(ge)(ge)工(gong)(gong)(gong)廠(chang)完成，或者(zhe)企業(ye)不具有自(zi)主切(qie)(qie)割(ge)(ge)能力，也(ye)要切(qie)(qie)割(ge)(ge)工(gong)(gong)(gong)廠(chang)加(jia)工(gong)(gong)(gong)。

介紹火苗切割，此方法在鋼(gang)板(ban)切割加(jia)工時較常見(jian)，是把能燃(ran)(ran)燒能產(chan)生高溫的染劑和(he)O2按照(zhao)一定的占比混(hun)和(he)，燃(ran)(ran)燒的時候用(yong)高溫把帶(dai)切割的鋼(gang)板(ban)氧化熔(rong)融，促使鋼(gang)板(ban)被制作成滿足條(tiao)件(jian)的款式(shi)。可(ke)供使用(yong)的燃(ran)(ran)料許多，或者(zhe)可(ke)以應用(yong)，也可(ke)以用(yong)或是丙烷等。是以前常見(jian)的燃(ran)(ran)料，但現(xian)在已經不再(zai)使用(yong)了。

折彎件孔邊間距

對于(yu)預先加工好的(de)孔(kong)(kong)(kong)坯，如果在(zai)折(zhe)(zhe)(zhe)(zhe)彎(wan)時孔(kong)(kong)(kong)位于(yu)折(zhe)(zhe)(zhe)(zhe)彎(wan)變形區(qu)，折(zhe)(zhe)(zhe)(zhe)彎(wan)后孔(kong)(kong)(kong)的(de)形狀會被拉伸變形，也會影響折(zhe)(zhe)(zhe)(zhe)彎(wan)后配件的(de)規格。為(wei)防止鋼板折(zhe)(zhe)(zhe)(zhe)彎(wan)標(biao)準孔(kong)(kong)(kong)距(ju)(ju)分布在(zai)彎(wan)曲變形區(qu)，孔(kong)(kong)(kong)邊(bian)距(ju)(ju)b（折(zhe)(zhe)(zhe)(zhe)彎(wan)后近從外側到孔(kong)(kong)(kong)邊(bian)的(de)距(ju)(ju)離）一(yi)般(ban)應(ying)(ying)保證大于(yu)等于(yu)厚度的(de)3倍.對于(yu)與(yu)折(zhe)(zhe)(zhe)(zhe)彎(wan)線平行的(de)橢圓孔(kong)(kong)(kong)，為(wei)保證折(zhe)(zhe)(zhe)(zhe)彎(wan)精度，避免孔(kong)(kong)(kong)距(ju)(ju)變形，孔(kong)(kong)(kong)邊(bian)距(ju)(ju)一(yi)般(ban)應(ying)(ying)≥4倍厚度。

如果孔距必須分布在(zai)變形區，為保(bao)證精度，先加工(gong)(gong)小孔，折彎后再鉆孔的方法即可滿(man)足要求，或在(zai)折彎部位沖加工(gong)(gong)孔或空位進行(xing)遷(qian)移變形區。
