Description
技术领域
本发明属于金属加工工艺技术领域,涉及一种金属正负极生产工艺。
背景技术
粉末冶金是制取金属粉末或用金属粉末(或金属粉末与非金属粉末的混合物)作为原料,经过成形和烧结,制造金属材料、复合材料以及各种类型制品的工艺技术;其中通过粉末冶金生产金属正负极是目前市面上较为普遍的加工方法;
但是目前市面上由粉末冶金工艺生产的金属正负极大多具有材料密度低、材质不均匀、机械性能低、不易成型薄壁、复杂结构件的缺点
发明内容
为了实现上述目的,本发明采用了以下技术方案:
一种金属正负极生产工艺,包括以下步骤:
S1:开模,对成型模具的型腔进行清洗,并将模具安装于注塑成型设备内部;
S2:注塑成型,将金属粉末及有机胶粘剂混合得到混合料并投入至注射机中,由注射机将混合料加热至一定的温度以相应的速度及压力注射至模具的型腔内;而后在模具内部冷却定型成金属正负极坯料;
S3:催化脱脂,将金属正负极坯料投入至催化脱脂设备中,通过催化脱脂设备将金属正负极坯料中的树脂,粘合剂,石蜡,硬质酸等杂质去除;
S4:高温烧结,将催化脱脂后的金属正负极坯料投入至高温烧结炉中,通过高温烧结炉将金属正负极坯料中的金属粉末在高温的烧结条件下发生相互流动、扩散、熔解、再结晶的物理化学反应,使金属正负极坯料进一步致密,消除其中的孔隙;
S5:电镀,将高温烧结后的金属正负极坯料投入至电镀设备中,通过电镀设备在金属正负极坯料的表面利用电解作用在其表面附着一层金属膜;完成加工得到金属正负极。
作为本发明进一步的方案:还包括:S4.5:整形抛光,将高温烧结后的金属正负极坯料进行整形打磨加工,将其打磨至规定的结构尺寸;而后对其表面进行抛光加工为电镀加工做预处理。
本发明的有益效果:该加工工艺适合应用于大批量生产小型、精密复杂及具有特殊要求的金属加工件;尤其适合针对金属正负极进行加工生产;
该工艺成型的金属正负极相较于传统的常规粉末冶金工艺成型的金属正负极,其加工工艺更少,在加工的过程中可实现少切屑甚至无切削的效果,整体的加工经济效益更高;
且该工艺成型的金属正负极有效的解决传统的常规粉末冶金工艺成型的金属正负极材料密度低、材质不均匀、机械性能低、不易成型薄壁、复杂结构件的缺点。
