拆电极又叫放电加工,在设计中一般叫拆铜公。铜公是紫铜,紫铜加工出来形状跟产品一样,放收缩之后用电脉冲对型芯或者型腔进行再加工,当然再加工也是有条件的,要么是电脑锣加工不到的地方(由于刀跟加工中心的设备或者客观原因上的问题),也有的就是产品的技术要求,比如是模具的生产周期要长一点,这样模具的温度要高一点,那么刀具很难加工或者不能加工的情况下就用铜公进行再加工,以便达到模具所需的要求。一般情况下:电脑锣是粗加工还需要用电脑加工出来的铜公再来放电,有的地方不能一次性加出来的铜公就必需拆了,所以就有了拆铜公。

论文题目:石墨电极生产工艺的研究
摘要
石墨电极,主要以石油焦、针状焦为原料,煤沥青作结合剂,经煅烧、配料、混捏、压型、焙烧、石墨化、机加工而制成,是在电弧炉中以电弧形式释放电能对炉料进行加热熔化的导体,以及在石墨电极生产过程中影响石墨电极质量的因素,并对如何提高石墨电极的质量提出了建议,指出了原材料质量的重要性,提出了添加炭纤维改善电极强度;改进电极接头形状,e5a48de588b减少接头故障提高电极寿命。
