當(dāng)今高強(qiáng)鋼、超高強(qiáng)鋼很好的實現(xiàn)了車輛的輕量化，提高了車輛的碰撞強(qiáng)度和安全性能，因此成為車用鋼材的重要發(fā)展方向。但隨著板料強(qiáng)度的提高，傳統(tǒng)的冷沖壓工藝在成型過程中容易產(chǎn)生破裂現(xiàn)象，無法滿足高強(qiáng)度鋼板的加工工藝要求。在無法滿足成型條件的情況下，國際上逐漸研究超高強(qiáng)度鋼板的熱沖壓成形技術(shù)。該技術(shù)是綜合了成形、傳熱以及組織相變的一種新工藝，主要是利用高溫奧氏體狀態(tài)下，板料的塑性增加，屈服強(qiáng)度降低的特點，通過模具進(jìn)行成形的工藝。但是熱成型需要對工藝條件、金屬相變、CAE分析技術(shù)進(jìn)行深入研究，該技術(shù)被國外廠商壟斷，國內(nèi)發(fā)展緩慢。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 由于熱作模具鋼工作條件的特點，因此會帶來以下方面的問題： </p> <p> （1）模腔表層金屬產(chǎn)生熱疲勞（龜裂）。熱作模具的工作特點是具有間歇性．每次使熱態(tài)金屬成形后都要用水、油、空氣等介質(zhì)冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復(fù)受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復(fù)的熱脹冷縮，即反復(fù)承受拉壓應(yīng)力作用．其結(jié)果引起模腔表面出現(xiàn)龜裂，稱為熱疲勞現(xiàn)象，由此，對熱模具鋼提出了第二個基本使用性能要求．即具有高的熱疲勞抗力。一般說來，影響鋼的熱疲勞抗力的因素主要有：①鋼的導(dǎo)熱性。鋼的導(dǎo)熱性高，可使模具表層金屬受熱程度降低，從而減小鋼的熱疲勞傾向性。一般認(rèn)為鋼的導(dǎo)熱性與合碳量有關(guān)，含碳量高時導(dǎo)熱性低，所以熱作模具鋼不宜采用高碳鋼。在生產(chǎn)中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會導(dǎo)致鋼的硬度和強(qiáng)度下降．也是不利的。②鋼的臨界點影響。通常鋼的臨界點（Acl）越高．鋼的熱疲勞傾向性越低。因此．一般通過加入合金元素Cr、W、Si、引來提高鋼的臨界點。從而提高鋼的熱疲勞抗。

淬透性主要取決于鋼的化學(xué)成分和淬火前的原始組織狀態(tài)；淬硬性則主要取決于鋼中的含碳量。對于大部分的冷作模具鋼，淬硬性往往是主要的考慮因素之一。對于熱作模具鋼和塑料模具鋼，一般模具尺寸較大，尤其是制造大型模具，其淬透性更為重要。另外，對于形狀復(fù)雜容易產(chǎn)生熱處理變形的各種模具，為了減少淬火變形，往往盡可能采用冷卻能力較弱的淬火介質(zhì)，如空冷、油冷或鹽浴冷卻，為了得到要求的硬度和淬硬層深度，就需要采用淬透性較好的模具鋼。 [2] </p> <p> 淬火溫度和熱處理變形 </p> <p> 為了便于生產(chǎn)，要求模具鋼淬火溫度范圍盡可能放寬一些，特別是當(dāng)模具采用火焰加熱局部淬火時，由于難于準(zhǔn)確地測量和控制溫度，就要求模具鋼有更寬的淬火溫度范圍。 </p> <p> 模具在熱處理時，尤其是在淬火過程中，要產(chǎn)生體積變化、形狀翹曲、畸變等，為保證模具質(zhì)量，要求模具鋼的熱處理變形小，特別是對于形狀復(fù)雜的精密模具，淬火后難以修整，對于熱處理變形程度的要求更為苛刻，應(yīng)該選用微變形模具鋼制造 </p> <p> <br /> </p> <p> <br />

決定模具使用壽命重要的因素往往是模具材料的耐磨性。模具在工作中承受相當(dāng)大的壓應(yīng)力和摩擦力，要求模具能夠在強(qiáng)烈摩擦下仍保持其尺寸精度。模具的磨損主要是機(jī)械磨損、氧化磨損和熔融磨損三種類型。為了改善模具鋼的耐磨性，就要既保持模具鋼具有高的硬度，又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。對于重載、高速磨損條件下服役的模具，要求模具鋼表面能形成薄而致密粘附性好的氧化膜，保持潤滑作用，減少模具和工件之間產(chǎn)生粘咬、焊合等熔融磨損，又能減少模具表面進(jìn)行氧化造成氧化磨損。所以模具的工作條件對鋼的磨損有較大的影響。 </p> <p> 耐磨性可用模擬的試驗方法，測出相對的耐磨指數(shù)，作為表征不同化學(xué)成分及組織狀態(tài)下的耐磨性水平的參數(shù)。以呈現(xiàn)規(guī)定毛刺高度前的壽命，反映各種鋼種的耐磨水平；試驗是以Cr12MoV鋼為基準(zhǔn)進(jìn)行對比。 </p> <p> <br /> </p> <p> <br /> 蚌埠模具鋼定制</p><p
