style="text-indent:25px">鈑金零件的工程師和鈑金材料的銷售商為保證終折彎成型后零件所期望的尺寸，會利用各種不同的算法來計算展開狀態(tài)下備料的實際長度。其中常用的方法就是簡單的“掐指規(guī)則”，即基于各自經(jīng)驗的算法。通常這些規(guī)則要考慮到材料的類型與厚度，折彎的半徑和角度，機床的類型和步進速度等等?？偨Y(jié)起來，如今被采納的較為流行的鈑金折彎算法主要有兩種，一種是基于折彎補償?shù)乃惴?，另一種是基于折彎扣除的算法。為了更好地理解在鈑金設(shè)計的計算過程中的一些基本概念，先了解以下幾點：1、折彎補償和折彎扣除兩種算法的定義，它們各自與實際鈑金幾何體的對應(yīng)關(guān)系；2、折彎扣除如何與折彎補償相對應(yīng)，采用折彎扣除算法的用戶如何方便地將其數(shù)據(jù)轉(zhuǎn)換到折彎補償算法；3、K因子的定義，實際中如何利用K因子，包括用于不同材料類型時K因子值的適用范圍。</p><p style="text-indent:25px">鋁板和銅板一般表面是不允許有劃傷的，有壓痕的。還有一點是比較特別的。折彎容易有裂紋。紫銅板一般不會有裂紋，黃銅板較差，鋁板很多型號折彎很容易出現(xiàn)裂紋。這就需要鈑金折彎師傅根據(jù)不同情況，采用不同折彎方法。熱軋鋼板是折彎中，怕折的材料，也是難折的材料。熱軋鋼板也就是SPHC，因其在軋制過程中，表面會生成一層很硬的四氧化三鐵。內(nèi)部材料力學(xué)性能延伸率也不是很好，在折彎過程中很容易出現(xiàn)裂紋。這個不是大的問題，大的問題是：熱軋鋼板如果買到便宜的材料，質(zhì)量不穩(wěn)定，內(nèi)部力學(xué)性能不一致，同一張板材材料厚度不一致。折彎角度忽大忽小，同一折彎角度不一致，調(diào)整合適后，在制作下一鈑金件，角度與前面的又不一致。充滿了不確定因素，所以，列為鈑金折彎難折的材料。我們在大街上常見的汽車鋼板機身，就是通過鈑金加工工藝制成的。</p><div
