style="text-indent:25px">坯料在模具型腔中塑性變性時(shí)，沿型腔表面既流動(dòng)又滑動(dòng)，使型腔表面與坯料間產(chǎn)生劇烈的摩擦，從而導(dǎo)致模具因磨損而失效。所以材料的耐磨性是模具較基本、較重要的性能之一。硬度是影響耐磨性的主要因素。一般情況下，模具零件的硬度越高，磨損量越小，耐磨性也越好。另外，耐磨性還與材料中碳化物的種類(lèi)、數(shù)量、形態(tài)、大小及分布有關(guān)。模具的工作條件大多十分惡劣，有些常承受較大的沖擊負(fù)荷，從而導(dǎo)致脆性斷裂。為防止模具零件在工作時(shí)突然脆斷，模具要具有較高的強(qiáng)度和韌性。模具的韌性主要取決于材料的含碳量、晶粒度及組織狀態(tài)。正確制定模具制造淬火加熱工藝規(guī)范，嚴(yán)格控制淬火加熱溫度和保溫時(shí)間。上海倒車(chē)鏡模具制造哪家好</p><p
