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(diǎn)是比較特別的。折彎容易有裂紋。紫銅板一般不會(huì)有裂紋，黃銅板較差，鋁板很多型號(hào)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(guò)程中，表面會(huì)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(guò)程中很容易出現(xiàn)裂紋。這個(gè)不是大的問(wèn)題，大的問(wèn)題是：熱軋鋼板如果買(mǎi)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(mǎn)了不確定因素，所以，列為鈑金折彎難折的材料。連云港鈑金加工哪家比較便宜常用的鈑金材料有不銹鋼、鍍鋅鋼板、馬口鐵、銅、鋁、鐵等。</p><div

style="text-indent:25px">鈑金彎曲件的小彎曲圓角半徑與材料的力學(xué)性能、表面質(zhì)量、硬化程度及纖維方向等因素有關(guān)。小彎曲圓角半徑只有在產(chǎn)品設(shè)計(jì)需要時(shí)才采用，一般情況下采用彎曲內(nèi)圓角等于或略小于板料厚度。產(chǎn)品要保證準(zhǔn)確的折彎尺寸，確定板料的展開(kāi)長(zhǎng)度是首要因素。由于折彎時(shí)板料外層受到拉伸變長(zhǎng)，內(nèi)層受到壓縮變短，只有中性層的長(zhǎng)度不變，在理論上中性層的長(zhǎng)度就等于料長(zhǎng)。而實(shí)際上同樣厚度的板料，由于材質(zhì)和硬度的不同，在折彎時(shí)硬度大的材料拉伸變形較小，中性層就靠外；硬度小的材料拉伸變形大，中性層就靠?jī)?nèi)，所以在計(jì)算展開(kāi)料長(zhǎng)時(shí)就需要折彎系數(shù)來(lái)補(bǔ)正。</p><p

style="text-indent:25px">鈑金常見(jiàn)的幾種表面處理方式為：拉絲、噴砂、噴漆、烤漆、噴粉、拋光、電鍍、陽(yáng)極氧化、絲印。由于某些鈑金材料表面不具備防銹防腐蝕的能力，所以進(jìn)行有效的表面處理是十分必要的。對(duì)鈑金件進(jìn)行表面處理可以提高產(chǎn)品在惡劣環(huán)境下的使用壽命，或者為了達(dá)到特定的表面效果或功能。所謂拉絲就是通過(guò)研磨材料對(duì)金屬表面進(jìn)行來(lái)回機(jī)械相對(duì)運(yùn)動(dòng)和化學(xué)腐蝕使工件表面光得到一層粗細(xì)分布均勻的宏觀(guān)指紋表面，主要作用是美化外觀(guān)。一般都是不銹鋼、鋁板、銅板等金屬板材，考慮用拉絲的表面處理方式。另外拉絲也叫擦紋，可分為手工拉絲和機(jī)械拉絲。鈑金折彎是大多數(shù)零部件成形的一道關(guān)鍵工序，折彎質(zhì)量的好壞直接影響產(chǎn)品的終形狀與性能。青浦區(qū)鈑金加工</p><p
