Snake). </p> <p> <br /> </p> <p> 彎刀（Cabriole)的調(diào)整有三種，一種是不讓它出現(xiàn)，在它出現(xiàn)的地方強壓。二是在出現(xiàn)后馬上反向強壓，三是在料條快出模具時強壓調(diào)整，讓它變形抵消彎刀。 </p> <p> <br /> </p> <p> 1. 是否是由于排樣是單載體所致,如是的話, 可在偏向的那側(cè)加一擋料塊, 也可先用加強壓料板之壓力來一試。 </p> <p> <br /> </p> <p> 2. 檢查和調(diào)整一下送料機。 </p> <p> <br /> </p> <p> 3. 檢查一下彎曲部分公母模的R角是否大小一樣,兩邊受力是否均衡(如果是U型彎曲的話)。 </p> <p> <br /> </p> <p> 4. 總之造成此現(xiàn)象的原因主要是"力"的問題 </p> <p> <br /> </p> <p> 在端子模中,尤其是汽車方面端子模中,多次折彎也是引發(fā)系帶變形的主要原因.局部強壓、調(diào)整機構(gòu)、合理的折彎工步及結(jié)構(gòu)都是不可少的。 </p> <p> <br /> </p><div style="width:100%;text-align:

凸、凹模的形狀、配合間隙和圓角半徑不僅對沖壓件成形有較大的影響,而且對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,沒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,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,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,在線切割加工中應(yīng)選擇合理的電規(guī)準,盡量減少變質(zhì)層深度。 </p> <p> <br
