Description

一种钨合金冷镦工艺润滑剂组合物
技术领域
本发明一种钨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
钨合金是以钨为基加入其他元素组成的合金。在金属中，钨的熔点最高，高温强度和抗蠕变性能以及导热、导电和电子发射性能都好，比重大，除大量用于制造硬质合金和作合金添加剂外，钨及其合金广泛用于电子、电光源工业，也在航天、铸造、武器等部门中用于制作火箭喷管、压铸模具、穿甲弹芯、触点、发热体和隔热屏等。
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。
