Description

一种锡合金冷镦工艺润滑剂组合物
技术领域
本发明一种锡合金冷镦工艺润滑剂组合物属于金属加工润滑剂领域。
背景技术
金属锡柔软,易弯曲,熔点231.89℃,沸点2260℃。有三种同素异形体:白锡为四方晶系,密度7.28克/厘米&sup3,硬度2,延展性好;灰锡为金刚石形立方晶系,密度5.75克/厘米³脆锡为正交晶系,密度6.54克/厘米&sup3。锡是人类使用的最古老的金属之一,随着锡的工业用途不断拓展,锡的开采、选矿、冶炼和加工得到了快速发展,逐步形成了门类齐全的锡产业。古老的锡仍然是现代工业不可缺少的关键稀有金属,号称“工业味精”,广泛应用于电子、信息、电器、化工、冶金、建材、机械、食品包装等行业。
冷镦加工是利用模具在常温下对金属棒料镦粗(常为局部镦粗)成形的锻造方法。冷镦是另一种形式的镦锻工艺。更具金属型变理论,在常温下对金属坯料施加一定的压力,使之在模腔产生变形。按规定的形状和尺寸成形。冷镦工艺广泛应用于中小零件以及各种类型的标准件。
冷镦工艺的主要特征是无切削加工,材料利用率高,利用率达80~90%,且金属材料流线不会被切断,因此成品强度比切削加工或铸造成型零件强度更高,在一定的批量生产条件下,冷镦加工成本要比其它加工成本低得多,适用于通常需要切削件以及紧固件等形状对称的产品加工。产品的尺寸精度、重量精度及力学性能等都能达到较高的要求。
