Description

一种高耐磨锤上模锻上模的制造方法
技术领域
本发明属于机械制造技术领域,更具体地说,涉及一种锤上模锻上模的制造方法。
背景技术
   利用金属在外力作用下所产生的塑性变形,来获得一定形状、尺寸和力学性能的原材料、毛坯或零件的生产方法,称为压力加工。而压力加工中的模锻,应用较为广泛,其具有以下特点:(1)模锻中的模膛能够引导金属的流动,可以加工形状复杂的锻件;(2)锻件内部的锻造流线比较完整,合理地利用流线组织,可提高零件的力学性能和使用寿命;(3)可以得到表面比较光洁、尺寸精度较高的锻件,即能够减小加工余量,节约加工时间;(4)操作简单、生产效率高,容易实现机械化。在通过锤上模锻进行压力加工时,金属在模膛中流动,以使得其充满整个模膛,因此其对于上模耐磨性要求较高,长时间的加工,其上模极容易磨损,不仅降低了上模的使用寿命,而且降低了模锻的精度。
发明内容
针对现有锤上模锻上模因长时间的挤压、摩擦而造成加工精度降低、寿命短的问题,本发明提供一种高耐磨锤上模锻上模的制造方法,通过改变锤头的毛坯组分,并进行真空渗碳处理,来提高其耐磨性,进而提高其加工精度,增加其使用寿命。
为解决上述问题,本发明采用如下的技术方案。
一种高耐磨锤上模锻上模的制造方法,包括以下步骤:
(1)上模材料的准备:
上模毛坯组分的质量百分比为:C:0.75-1.25%、Cr:10.20-13.55%、Mn:0.65-0.80 %、Si:0.15-0.25 %、P:≦0.03%,其余为Fe;
(2)毛坯的锻造:
将坯料放在高频感应加热炉中加热到始锻温度,再将加热的坯料放入模锻中进行锻造;
(3)上模的清洗:
将工件清洗,并放入真空渗碳炉;
(4)上模的升温及均热:
将真空渗碳炉抽真空至40Pa后开始升温,加热到850-890℃,保温20分钟;
(5)上模真空渗碳的渗碳期:
渗碳剂采用乙炔,纯度大于98%,渗碳气流量为使炉压的增加速度为40Pa/s,直到炉内气压为2.8-3.2×104Pa,渗碳时间为240-270分钟;
(6)上模真空渗碳的扩散期:
扩散期的真空度为20-26Pa,扩散时间为160-180分钟;
(7)上模真空渗碳后的热处理:
渗碳完成后,零件在炉内冷却到540-560℃,并通过液氮快速冷却,然后出炉,其后在-50--70℃温度下保温5小时,冷处理后进行140-170℃保温4小时的回火处理。
优选的,所述的步骤(1)中,上模毛坯组分的质量百分比为:C:0.95%、Cr:12.50%、Mn:0.70 %、Si:0.20 %、P:≦0.03%,其余为Fe。
优选的,所述的步骤(5)中,炉内气压为3.00×104Pa,渗碳时间为250分钟。
相比于现有技术,本发明的有益效果为:
(1)本发明通过改变上模的毛坯组分,并通过真空渗碳处理来提高上模的耐磨性,使得锤上模锻的加工精度得到提高,上模的寿命也得到了增加。
(2)本发明方法简单,成本低,加工容易。
