凸、凹模的形狀、配合間隙和圓角半徑不僅對(duì)沖壓件成形有較大的影響,而且對(duì)于模具的磨損及壽命也影響很大。如模具的配合間隙直接影響沖裁件質(zhì)量和模具壽命。精度要求較高的,宜選較小的間隙值；反之則可適當(dāng)加大間隙,以提高模具壽命。人為的拉線線割,線割間隙處理不對(duì),沒(méi)作清角及線割的變質(zhì)層影響。 </p> <p> 沖模刃口多采用線切割加工。由于線切割加工的熱效應(yīng)和電解作用，廣州沖壓精密五金模具,使模具加工表面產(chǎn)生一定厚度的變質(zhì)層,造成表面硬度降低，廣州沖壓精密五金模具,出現(xiàn)顯微裂紋等,致使線切割加工的沖模易發(fā)生早期磨損,直接影響模具沖裁間隙的保持及刃口容易崩刃,縮短模具使用壽命。因此，廣州沖壓精密五金模具,在線切割加工中應(yīng)選擇合理的電規(guī)準(zhǔn),盡量減少變質(zhì)層深度。

沖壓生產(chǎn)中**常用的材料是金屬材料（包括黑色金屬和有色金屬），但有時(shí)也用非金屬材料。其中黑色金屬主要有普通碳素結(jié)構(gòu)鋼、質(zhì)量碳素結(jié)構(gòu)鋼、合金結(jié)構(gòu)鋼、碳素工具鋼、不銹鋼、電工硅鋼等；有色金屬主要有純銅、黃銅、青銅、鋁等；非金屬材料有紙板、層壓板、橡膠板、塑料板、纖維板和云母等。 </p> <p> <br /> </p> <p> 沖壓用金屬材料的供應(yīng)狀態(tài)一般是各種規(guī)格的板料和帶料。板料可用于工程模的生產(chǎn)，帶料（卷料）用于連續(xù)模的生產(chǎn)，也可以用于工程模的生產(chǎn)。板料的尺寸較大，可用于大型零件的沖壓，也可以將板料按排樣尺寸剪裁成條料后用于中小型零件的沖壓；帶料（又稱(chēng)卷料）有各種規(guī)格的寬度，展開(kāi)長(zhǎng)度可達(dá)幾十米，成卷狀供應(yīng)，適應(yīng)于連續(xù)模大批量生產(chǎn)的自動(dòng)送料。
