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)分布均勻的宏觀指紋表面，主要作用是美化外觀。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。</p><p style="text-indent:25px">預(yù)先加工好孔的毛坯料，在彎曲時(shí)如果孔位于彎曲變形區(qū)內(nèi)，那么孔的形狀在折彎后會(huì)拉伸變形，同時(shí)也會(huì)影響折彎后配件尺寸。為了避免孔位分布在折彎變形區(qū)內(nèi)，一般應(yīng)保證孔邊距離b（折彎后外邊至孔邊的近距離）≥3倍板厚。對(duì)于平行于彎曲線的橢圓形孔，為保證折彎精度和防止孔位變形，孔邊距離一般應(yīng)≥4倍板厚。如果孔位必須分布在變形區(qū)內(nèi)，則為了保證精度，一般采用先加工小孔，待折彎后再擴(kuò)孔的方法達(dá)到要求，也可在折彎位置沖工藝孔或缺口來(lái)轉(zhuǎn)移變形區(qū)。鈑金具有重量輕、強(qiáng)度高、導(dǎo)電（能夠用于電磁屏蔽）、成本低、大規(guī)模量產(chǎn)性能好等特點(diǎn)。</p><div
