<br /> </p> <p> 在工作過(guò)程中，模具承受著沖擊載荷，為了減少在使用過(guò)程中的折斷、崩刃等形式的損壞，要求模具鋼具有一定的韌性。 </p> <p> 模具鋼的化學(xué)成分，晶粒度，純凈度，碳化物和夾雜物等的數(shù)量，聊城NAK80模具鋼、形貌、尺寸大小及分布情況，聊城NAK80模具鋼，以及模具鋼的熱處理制度和熱處理后得到的金相組織等因素都對(duì)鋼的韌性帶來(lái)很大的影響。特別是鋼的純凈度和熱加工變形情況對(duì)于其橫向韌性的影響更為明顯。鋼的韌性、強(qiáng)度和耐磨性往往是相互矛盾的。因此，要合理地選擇鋼的化學(xué)成分并且采用合理的精煉、熱加工和熱處理工藝，以使模具材料的耐磨性、強(qiáng)度和韌性達(dá)到配合。 </p> <p> 沖擊韌性系表特征材料在一次沖擊過(guò)程中試樣在整個(gè)斷裂過(guò)程中吸收的總能量。但是很多工具是在不同工作條件下疲勞斷裂的，因此，常規(guī)的沖擊韌性不能反映模具鋼的斷裂性能，聊城NAK80模具鋼。小能量多次沖擊斷裂功或多次斷裂壽命和疲勞壽命等試驗(yàn)技術(shù)正在被采用。 </p> <p> <br /> </p> <p> <br />

</p> <p> 密度是物質(zhì)的特性之一，每種物質(zhì)都有一定的密度，不同物質(zhì)的密度一般是不同。因此我們可以利用密度來(lái)鑒別物質(zhì)。所以我們可以根據(jù)密度公式ρ=M/V，計(jì)算出任意一種模具鋼的密度。 </p> <p> 根據(jù)密度公式：ρ=m/v，也就是說(shuō)決定模具鋼質(zhì)量和體積的因素決定了模具鋼密度。那么從微觀的角度來(lái)講的話，就是分子量和分子間隙共同決定物質(zhì)的密度。體積、大小、質(zhì)量、壓強(qiáng)、壓力和溫度影響物質(zhì)密度，雖然物質(zhì)密度物質(zhì)的本身屬性，它是一定的，但是物質(zhì)有各種狀態(tài)，當(dāng)物質(zhì)形成態(tài)的轉(zhuǎn)化的時(shí)候，密度才會(huì)變化。比如水，升溫可導(dǎo)致水的氣化，密度變小，加壓又可以使水蒸氣從新凝結(jié)為液態(tài)水，密度變大。

模具鋼材特性有哪些？總的來(lái)說(shuō)，模具鋼材是使用特殊煉鋼技術(shù)和嚴(yán)密質(zhì)量控制后得到的高純度以及組織極其微細(xì)的熱作模具鋼材料，它比一般傳統(tǒng)煉制的H13模具鋼材各項(xiàng)適用參數(shù)性能更佳，主要特征為高低溫均有良好的耐磨性、優(yōu)良的韌性和延展性、穩(wěn)定的機(jī)加工性和拋光性、優(yōu)良的高溫強(qiáng)度和抗熱疲勞性、良好的淬透性和微熱處理變形性。熱作模具鋼材主要運(yùn)用在： </p> <p> 1.塑膠模具（注塑模具與壓塑傳遞模建議使用硬度50-52HRC）； </p> <p> 2.擠壓模具（模仁建議使用硬度45-50HRC；模托、模座、襯套、滑塊、頂桿建議40-48HRC）； </p> <p> 3.厚鋼板冷沖（廢鋼剪切、熱剪切建議使用硬度45-52HRC）； </p> <p> 4.模具套環(huán)（如陶瓷硬質(zhì)合金模建議使用硬度45-50HRC）； </p> <p> 5.耐磨損零件（建議使用硬度50-52HRC）； </p> <p> 6.壓鑄模、鍛模等； </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 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，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(lèi)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(lèi)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，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(guò)共析鋼或萊氏體鋼。常用的鋼類(lèi)有高碳低合金鋼、高碳高鉻鋼、鉻鉬鋼、中碳鉻鎢釧鋼等。

src="https://tyunfile.71360.com/UploadFile/wxtdmj/637438965354906173/2337394.png"></div><p> 強(qiáng)度性能： </p> <p> （1）硬度硬度是模具鋼的主要技術(shù)指標(biāo)，模具在高應(yīng)力的作用下欲保持其形狀尺寸不變，必須具有足夠高的硬度。冷作模具鋼在室溫條件下一般硬度保持在HRC60左右，熱作模具鋼根據(jù)其工作條件，一般要求保持在HRC40~55范圍。對(duì)于同一鋼種而言，在一定的硬度值范圍內(nèi)，硬度與變形抗力成正比；但具有同一硬度值而成分及組織不同的鋼種之間，其塑性變形抗力可能有明顯的差別。 </p> <p> （2）紅硬性在高溫狀態(tài)下工作的熱作模具，要求保持其組織和性能的穩(wěn)定，從而保持足夠高的硬度，這種性能稱為紅硬性。碳素工具鋼、低合金工具鋼通常能在180~250℃的溫度范圍內(nèi)保持這種性能，鉻鉬熱作模具鋼一般在550~600℃的溫度范圍內(nèi)保持這種性能。鋼的紅硬性主要取決于鋼的化學(xué)成分和熱處理工藝。 </p> <p> <br />

</p> <p> <br /> </p> <p> <br /> </p> <p> 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(guò)早地?cái)嗔?，是熱作模具失效的主要原因之一。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(méi)有高的強(qiáng)度和良好的韌性，就容易開(kāi)裂。 </p> <p> <br /> </p> <p> <br /> 聊城NAK80模具鋼</p><p
