Description
技术领域
本发明涉及一种合金钢组合物,尤其涉及一种可用于塑料加工模具表面、以及降低金属屑粘附的耐腐蚀合金钢组合物。
背景技术
塑料制品加工过程中,模具是重要的工具,其用于注塑、吹塑、挤出、压铸或锻压成型、冶炼、冲压等方法得到所需产品,素有“工业之母”的称号。模具是精密工具,形状复杂,承受坯料的胀力,对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求,模具生产的发展水平是机械制造水平的重要标志之一。
金属加工中应用到的切刀等刀具,在切、削、铣等过程中,会产生大量的金属屑,尤其是铝合金切割时,铝屑漂浮在空中。目前主要的解决方案是配置有吸尘功能或者防护罩的功能装置,把吸尘器加在切割机设备上,通过吸尘器的功解决该问题,但是不是所有的设备都能匹配吸尘器,也就是说,有的设备上面无法安装吸尘器,就要对这台设备增加相应的排序以及吸屑的功能。
加工过程中产生金属屑牢固的附着于刀具表面,一方面导致刀具表面磨损严重,另一方面会降低加工产品表面性能。这已经成为金属加工行业面临的普遍问题。为此,如何解决刀具对金属屑的吸附,是急需解决的问题。
