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，確定板料的展開長度是首要因素。由于折彎時(shí)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(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，中性層就靠內(nèi)，寶山區(qū)鈑金加工廠家哪家好，寶山區(qū)鈑金加工廠家哪家好，所以在計(jì)算展開料長時(shí)就需要折彎系數(shù)來補(bǔ)正，寶山區(qū)鈑金加工廠家哪家好。正常鈑金折彎時(shí)，鈑金材料和折彎下模有滑動摩擦，會形成折痕。寶山區(qū)鈑金加工廠家哪家好</p><div

style="text-indent:25px">鈑金加工一般用到的材料有冷軋板（SPCC）、熱軋板（SHCC）、鍍鋅板（SECC、SGCC），銅（CU）黃銅、紫銅、鈹銅，鋁板（6061、5052、1010、1060、6063、硬鋁等），不銹鋼（鏡面、拉絲面、霧面），根據(jù)產(chǎn)品作用不同，選用材料不同，一般需從產(chǎn)品其用途及成本上來考慮。1．冷軋板SPCC，主要用電鍍和烤漆件，成本低，易成型，材料厚度≤3.2mm。2．熱軋板SHCC，材料T≥3.0mm ,也是用電鍍,烤漆件，成本低，但難成型，主要用平板件。3．鍍鋅板SECC、SGCC。SECC電解板分N料、P料，N料主要不作表面處理，成本高，P料用于噴涂件。4．銅；主要用導(dǎo)電作用料件，其表面處理是鍍鎳、鍍鉻，或不作處理，成本高。5．鋁板；一般用表面鉻酸鹽（J11-A），氧化（導(dǎo)電氧化，化學(xué)氧化），成本高，有鍍銀，鍍鎳。6．鋁型材；截面結(jié)構(gòu)復(fù)雜的料件，大量用于各種插箱中。表面處理同鋁板。7．不銹鋼；主要用不作任何表面處理，成本高。鈑金件在滿足強(qiáng)度及功能的前提下，越薄越好。</p><div
