style="text-indent:25px">引伸凹模之設(shè)計:引伸凹模角隅部形狀及逃角形狀是非常重要的設(shè)計事項，有關(guān)角隅部及逃角之形狀及特征如下：引伸凹模R角值大時較易引伸加工，但亦產(chǎn)生引伸產(chǎn)品表面產(chǎn)生皺摺現(xiàn)象，引伸制品側(cè)壁厚度大于板厚。引伸厚板件及頂出困難之場合，凹模R值要取小，約為板厚之1-2倍，一般上圓筒及方筒引伸凹模之大多引伸部作成直段狀，為防止燒著發(fā)生、潤滑油油膜之破壞及減少頂出力等目的，直段部下方宜有逃部(階段形或推拔形)設(shè)計。特別是引縮加工之場合，此直段部有必要盡量少。</p><p style="text-indent:25px">模具工作過程中，在循環(huán)應(yīng)力的長期作用下，往往導(dǎo)致疲勞斷裂。其形式有小能量多次沖擊疲勞斷裂、拉伸疲勞斷裂接觸疲勞斷裂及彎曲疲勞斷裂。模具的疲勞斷裂性能主要取決于其強(qiáng)度、韌性、硬度、以及材料中夾雜物的含量。當(dāng)模具的工作溫度較高進(jìn)，會使硬度和強(qiáng)度下降，導(dǎo)致模具早期磨損或產(chǎn)生塑性變形而失效。因此，模具材料應(yīng)具有較高的抗回火穩(wěn)定性，以保證模具在工作溫度下，具有較高的硬度和強(qiáng)度。有些模具在工作過程中處于反復(fù)加熱和冷卻的狀態(tài)，使型腔表面受拉、壓力變應(yīng)力的作用，引起表面龜裂和剝落，增大摩擦力，阻礙塑性變形，降低了尺寸精度，從而導(dǎo)致模具失效。冷熱疲勞是熱作模具失效的主要形式之一，幫這類模具應(yīng)具有較高的耐冷熱疲勞性能。模具制造熱處理的，磨削工藝不當(dāng)。</p><div
