冷軋模具鋼包括冷沖模、拉絲模、拉延模、壓印模、搓絲模、滾絲板、冷鐓模和冷擠壓模等。冷作模具用鋼，安徽SKD61模具鋼，按其所制造具的工作條件，應(yīng)具有高的硬度、強(qiáng)度、耐磨性、足夠的韌性，以及高的淬透性、淬硬性和其他工藝性能。用于這類用途的合金工具用鋼一般屬于高碳合金鋼，碳質(zhì)量分?jǐn)?shù)在0.80%以上，鉻是這類鋼的重要合金元素，其質(zhì)量分?jǐn)?shù)通常不大于5%。但對(duì)于一些耐磨性要求很高，淬火后變形很小模具用鋼，鉻質(zhì)量分?jǐn)?shù)可達(dá)13%，并且為了形成大量碳化物，鋼中碳質(zhì)量分?jǐn)?shù)也很高，安徽SKD61模具鋼，可達(dá)2.0%~2.3%。冷作模具鋼的碳含量較高，其組織大部分屬于過共析鋼或萊氏體鋼。常用的鋼類有高碳低合金鋼、高碳高鉻鋼、鉻鉬鋼、中碳鉻鎢釧鋼等，安徽SKD61模具鋼。

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(duì)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(duì)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(duì)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(shí)，由于難于準(zhǔn)確地測(cè)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(shí)，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(duì)于形狀復(fù)雜的精密模具，淬火后難以修整，對(duì)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 />

熱作模具鋼在工作時(shí)承受著很大的沖擊力，模腔和高溫金屬接觸，反復(fù)地加熱和冷卻，其使用條件極其惡劣。為了滿足熱作模具的使用要求，熱作模具鋼應(yīng)具備下列基本特性： </p> <p> (1)高的熱穩(wěn)定性。熱穩(wěn)定性是指鋼材在高溫下可長(zhǎng)時(shí)間保持其常溫力學(xué)性能的能力。熱作模具工作時(shí)，接觸的是熾熱的金屬，甚至是液態(tài)金屬，所以模具表面溫度很高，一般為400～700℃。這就要求熱作模具鋼在高溫下不發(fā)生熱化，具有高的熱穩(wěn)定性，否則模具就會(huì)發(fā)生塑性變形，造成堆塌而失效。 </p> <p> <br /> </p> <p> (2)優(yōu)良的耐熱疲勞性，熱作模具的工作特點(diǎn)是反復(fù)受熱受冷，模具一時(shí)受熱膨脹，一時(shí)又冷卻收縮，形成很大的熱應(yīng)力，而且這種熱應(yīng)力是方向相反，交替產(chǎn)生的。在反復(fù)熱應(yīng)力作用下，模具表面會(huì)形成網(wǎng)狀裂紋(龜裂)，這種現(xiàn)象稱為熱疲勞，模具因熱疲勞而過早地?cái)嗔眩菬嶙髂＞呤У闹饕蛑?。所以熱作模具鋼必須要有良好的熱疲勞性?</p> <p> (3)較高的高溫強(qiáng)度和良好的韌性。熱作模具，尤其是熱鍛模，工作時(shí)承受很大的沖擊力，而且沖擊頻率很高，如果模具沒有高的強(qiáng)度和良好的韌性，就容易開裂。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼在服役條件下除了承受載荷的周期性變化之外，還受到高溫及周期性的急冷急熱的作用，因此，評(píng)價(jià)熱作模具鋼的斷裂抗力應(yīng)重視材料的熱機(jī)械疲勞斷裂性能。熱機(jī)械疲勞是一種綜合性能的指標(biāo)，它包括熱疲勞性能、機(jī)械疲勞裂紋擴(kuò)展速率和斷裂韌性三個(gè)方面。 </p> <p> 熱疲勞性能反映材料在熱疲勞裂紋萌生之前的工作壽命，抗熱疲勞性能高的材料，萌生熱疲勞裂紋的熱循環(huán)次數(shù)較多；機(jī)械疲勞裂紋擴(kuò)展速率反映材料在熱疲勞裂紋萌生之后，在鍛壓力的作用下裂紋向內(nèi)部擴(kuò)展時(shí)，每一應(yīng)力循環(huán)的擴(kuò)展量；斷裂韌性反映材料對(duì)已存在的裂紋發(fā)生失穩(wěn)擴(kuò)展的抗力。斷裂韌性高的材料，其中的裂紋如要發(fā)生失穩(wěn)擴(kuò)展，必須在裂紋前端具有足夠高的應(yīng)力強(qiáng)度因子，也就是必須有較大的裂紋長(zhǎng)度。在應(yīng)力恒定的前提下，在一種模具中已經(jīng)存在一條疲勞裂紋，如果模具材料的斷裂韌性值較高，則裂紋必須擴(kuò)展得更深，才能發(fā)生失穩(wěn)擴(kuò)展。 </p> <p> 也就是說，抗熱疲勞性能決定了疲勞裂紋萌生前的那部分壽命；而裂紋擴(kuò)展速率和斷裂韌性，可以決定當(dāng)裂紋萌生后發(fā)生亞臨界擴(kuò)展的那部分壽命。因此，熱作模具如要獲得高的壽命，模具材料應(yīng)具備高的抗熱疲勞性能、低的裂紋擴(kuò)展速率和高的斷裂韌性值。 </p> <p> <br /> </p> <p> <br />

模具鋼深冷處理工藝是怎樣的？深冷處理的作用性非常大，近期有很多客戶來咨詢模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類的問題，天成模具小編在這里為大家詳細(xì)解答下，模具鋼深冷處理工藝是怎樣的。模具鋼深冷處理一般在零下196℃進(jìn)行。DC53模具鋼板材深冷正常的處理工藝如下：一般在淬火和回火工序之間進(jìn)行，也能在淬火回火之后進(jìn)行深冷處理。但是有一種情況要注意，如果在淬火、回火后鋼中仍保留有殘余奧氏體，則在深冷處理后仍需要再進(jìn)行一次回火。深冷處理能提高鋼的耐磨性和抗回火穩(wěn)定性。深冷處理不僅用于冷作模具，也可用于熱作模具和硬質(zhì)合金。

<br /> </p> <p> 模具鋼廠在生產(chǎn)模具鋼時(shí)，需要根據(jù)不同的模具來使用合適的鋼材。其中塑膠模具鋼的使用較為頻繁。一般情況下塑膠模具在制造過程中，需要花費(fèi)極多成本進(jìn)行加工和拋光，因此模具鋼廠在選用模具的材料時(shí)，應(yīng)當(dāng)在保證模具使用性能要求的基礎(chǔ)上，盡量的提高模具鋼的可加工性。那么，塑膠模具鋼如何選材呢？1、根據(jù)塑膠制品的種類選用 </p> <p> 不同的塑膠制品的質(zhì)量和加工方法不同，因此模具鋼廠可以根據(jù)塑料制品的質(zhì)量和加工方法的不同來選用適合的模具鋼，使得模具鋼在保證成本的同事，又具備可加工性。2、根據(jù)塑膠制品的大小和精度選用 </p> <p> 不同的塑膠制品的大小，精度等不盡相同，模具鋼廠可以根據(jù)塑膠制品不同的尺寸和精度的要求來進(jìn)行模具鋼的選用，對(duì)一些精度高，生產(chǎn)量大的塑膠制品，可以使用預(yù)硬化鋼材，可以有效的防止熱處理時(shí)模具鋼出現(xiàn)變形的可能。3、根據(jù)塑膠制品的復(fù)雜程度選用 </p> <p> 塑膠制品有些結(jié)構(gòu)比較簡(jiǎn)單，有些則相對(duì)較為復(fù)雜，那些相對(duì)復(fù)雜一些的塑膠制品，其加工工藝也會(huì)相對(duì)復(fù)雜一些，國(guó)內(nèi)**的模具鋼廠一般可以提前預(yù)見到產(chǎn)品需要經(jīng)歷的復(fù)雜程度，因此可以根據(jù)難易程度，選用具有易切削、熱處理時(shí)不易變形、耐磨性高等特質(zhì)的模具鋼來生產(chǎn)。
