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)計需要時才采用，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，確定板料的展開長度是首要因素。由于折彎時板料外層受到拉伸變長，內(nèi)層受到壓縮變短，只有中性層的長度不變，在理論上中性層的長度就等于料長。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，中性層就靠內(nèi)，所以在計算展開料長時就需要折彎系數(shù)來補(bǔ)正。青浦區(qū)鈑金加工廠商鈑金圖紙到手后，根據(jù)展開圖及批量的不同選擇不同落料方式，其中有激光，數(shù)控沖床，剪板，模具等方式。</p><div

style="text-indent:25px">預(yù)先加工好孔的毛坯料，在彎曲時如果孔位于彎曲變形區(qū)內(nèi)，那么孔的形狀在折彎后會拉伸變形，同時也會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轉(zhuǎn)移變形區(qū)。</p><p style="text-indent:25px">鈑金件產(chǎn)品是由片材加工而成的，在沒有加工之前，原材料是平整的，所以，在設(shè)計鈑金件時，所有折彎及斜面都要能展開在同一個平面上，相互之間不能有干涉。鈑金件厚度從0.03?4.00mm各種規(guī)格都有，但厚度越大越難加工，就越需要大的加工設(shè)備，不良率也隨之增加。厚度應(yīng)根據(jù)產(chǎn)品實(shí)際的功能來選擇，在滿足強(qiáng)度及功能的前提下，越薄越好，對于大部分產(chǎn)品，鈑金件厚度應(yīng)控制在1.00mm以下。鈑金件產(chǎn)品要符合加工工藝，要易于制造，不符合加工工藝的產(chǎn)品是制造不出來的，就是不合格的設(shè)計。鈑金的表面處理主要是二大方式：噴塑（噴粉）和噴油。大件通常用噴塑，小件可以用噴油。</p><div
