Description

一种抗裂易散热拉伸模材料
技术领域:
本发明涉及拉伸成型领域,具体讲是一种抗裂易散热拉伸模材料。
背景技术:
目前,利用拉伸模具进行拉伸成型的拉伸材料一般采用CR12mov或者QT300等一些常见金属材料,拉伸模散热和硬度无法满足深拉伸模具要求,从而容易在拉伸过程中出现破裂问题。
发明内容:
本发明所要解决的技术问题是,提供一种散热效果好,强度和韧性足的抗裂易散热拉伸模材料。
本发明的技术解决方案是,提供一种抗裂易散热拉伸模材料,拉伸模材料的成分具有以下质量百分比含量:96-98.2%的Fe,0.30-0.5%的Si,0.35%-0.5%的Mn,0.47-0.55%的Cu,0.46-0.55%的Cr,0.21-0.3%的Mo。硅是改善流动性能的主要成分,另外,硅可以改善抗拉强度,但由于结晶析出的硅易形成硬点而使延伸率降低,因此硅的含量应该以合理的区间设置,本发明平衡了硅的优缺点,进而使得其含量的控制实现了抗拉伸性能的提升,但同时,又减少了其副作用的产生。铜含量超过0.35%可以明显增强度,并且铜具有良好的导热性。钼则可以改善耐热性和韧性,并且具有较好耐腐蚀性,对于拉伸产品的后期使用非常有好处。
作为优选的技术方案,还包括0.03-0.08%的Ti。适量的钛可用于提高合金的机械性能。
作为优选的技术方案,还包括0.08-0.02%的Ni。镍和铜一样,有增加抗拉强度和导热性的倾向,可通过加入镍来改善高温强度耐热性,但对于量的把控很重要,其含量不宜高于0.02%。
作为优选的技术方案,还包括球化剂1.4-1.8%。球化剂中含有镁,如果镁的含量过高,就会使流动性变差而对拉伸造成副作用,故选用合适的球化剂很重要。
作为优选的技术方案,拉伸模材料的成分具有以下质量百分比含量:66%的18#生铁,1.6%的球化剂Z-2,30%的废钢CR12mov,0.55%的75#硅铁,0.8%的65#锰铁,0.8%的铬铁,0.5%的钼铁,0.6%的电解铜,废钢为CR12mov,铬铁中含有67%~71%的Cr,钼铁牌号为FeMo70。
本发明相比于现有技术具有以下优点:通过上述拉伸膜材料能解决深拉伸过程中不破裂,产生的热量能及时散热,表面拉伸走料顺畅,使产品表面平整光滑。
具体实施方式:
下面结合具体实施方式对本发明作进一步说明:
实施例
一种抗裂易散热拉伸模材料,拉伸模材料的成分具有以下质量百分比含量:97.3%的Fe,0.35%的Si,0.35%的Mn,0.5%的Cu,0.46%的Cr,0.23%的Mo,0.05%的Ti,0.01%的Ni,余量为C。
实施例2
为方便采购和加工,拉伸模材料的成分具有以下质量百分比含量:66%的18#生铁,1.6%的球化剂Z-2,30%的废钢CR12mov,0.55%的75#硅铁,0.8%的65#锰铁,0.8%的铬铁,0.5%的钼铁,0.6%的电解铜,废钢为CR12mov,铬铁中含有67%~71%的Cr,钼铁牌号为FeMo70。
其中,硅是改善流动性能的主要成分,另外,硅可以改善抗拉强度,但由于结晶析出的硅易形成硬点而使延伸率降低,因此硅的含量应该以合理的区间设置,本发明平衡了硅的优缺点,进而使得其含量的控制实现了抗拉伸性能的提升,但同时,又减少了其副作用的产生。铜含量超过0.35%可以明显增强度,并且铜具有良好的导热性。钼则可以改善耐热性和韧性,并且具有较好耐腐蚀性,对于拉伸产品的后期使用非常有好处。而且,适量的钛可用于提高合金的机械性能。另外,镍和铜一样,有增加抗拉强度和导热性的倾向,可通过加入镍来改善高温强度耐热性。
本发明采用合金铸铁的材质通过对比,以前用QT300进行铸造,在拉伸中拉伸原材料发热情况严重,导致拉伸过程中破裂,且材料硬度达不到2.5mm厚度酸洗板拉伸的要求,在材质中增加铬和铜等其他元素的比例来达到深拉伸的要求。并且,通过上述拉伸膜材料能解决深拉伸过程中不破裂,产生的热量能及时散热,表面拉伸走料顺畅,使产品表面平整光滑。
以上仅就本发明较佳的实施例作了说明,但不能理解为是对权利要求的限制。
