實踐證明,模具的熱加工質(zhì)量對模具的性能與使用壽命影響甚大。從模具失效原因的分析統(tǒng)計可知,因熱處理不當(dāng)所引發(fā)模具失效“***”約占40％以上。模具工作零件的淬火變形與開裂,使用過程的早期斷裂,均與摸具的熱加工工藝有關(guān)。 </p> <p> <br /> </p> <p> 這是模具工作零件制造過程中的重要環(huán)節(jié)。對于高合金工具鋼的模具,通常對材料碳化物分布等金相組織提出技術(shù)要求。此外,還應(yīng)嚴(yán)格控制鍛造溫度范圍,制定正確的加熱規(guī)范,采用正確的鍛造力法,以及鍛后緩冷或及時退火等。 </p> <p> <br />

style="text-indent:25px">不同材質(zhì)的模具壽命往往不同。為此,對于沖模工作零件材料提出兩項基本要求:①材料的使用性能應(yīng)具有高硬度(58~64HRC)和**度,并具有高的耐磨性和足夠的韌性,熱處理變形小,有一定的熱硬性；②工藝性能良好。沖模工作零件加工制造過程一般較為復(fù)雜．因而必須具有對各種加工工藝的適應(yīng)性,如可鍛性、可切削加工性、淬硬性、淬透性、淬火裂紋敏感性和磨削加工性等。通常根據(jù)沖壓件的材料特性、生產(chǎn)批量、精度要求等,選擇性能優(yōu)良的模具材料,同時兼顧其工藝性和經(jīng)濟(jì)性。</p><p> a. 模具朝小型化 </p> <p> <br /> </p> <p> 由于線割放電加工（WEDM）技術(shù)之發(fā)展使其加工精度及表面品質(zhì)得以提高，因此利用WEDM方式進(jìn)行母模塊或壓料板入塊之加工漸有替代研磨加工之可能，如此可減少沖壓工程站數(shù)（空站之設(shè)計可減少）而使模具尺寸大幅縮小。為配合高速沖床之規(guī)格，多腳數(shù)導(dǎo)線架（100 pins以上）之沖切模具尺寸達(dá)1200 mm以上長度，故其沖壓生產(chǎn)方式必須采沖床串行布置型。 </p> <p> <br /> </p> <p> b. 模具組件朝小型化及高精度化 </p> <p> <br /> </p> <p> 以多腳數(shù)導(dǎo)線架用導(dǎo)腳沖切沖頭為例，其形狀、尺寸之動向朝外形尺寸縮小、刃部長度減短、沖頭厚度更薄發(fā)展，而其精度動向朝高精密、低加工面粗度進(jìn)展。為了達(dá)到如此高精度（尺寸公差±2 μm以下）及低表面粗度（0.3 μm Ra以下）之要求，使用高精度研磨設(shè)備及低表面粗度之線割放電加工機(jī)是必要的。 </p> <p> <br /> 正常情況下，其運用壽命是切削絲錐的3～20倍。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣州本地精密五金模具加工,精密五金模具"

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，精密五金模具材料應(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。更高的出產(chǎn)功率。正是由于有了更長的運用壽命，更快的加工速度，運用揉捏絲錐能下降更換絲錐和待機(jī)的時刻，然后進(jìn)步出產(chǎn)功率。
