Description

一种金合金旋压加工工艺润滑剂组合物
技术领域
本发明一种金合金旋压加工工艺润滑剂组合物领域属于金属加工润滑剂领域。
背景技术
金合金是以金为主要组分与其他元素组成的贵金属材料。为了适应各种工业应用，须进一步改善纯金的性能，如提高强度和耐磨性，改变电学性能等，往往在金中添加其他元素构成金合金。合金元素的加入使金的电阻率显著增加，其中铁的作用较明显，银、铜和钯的作用较弱。在使金强化的合金元素中，钴和镍的强化作用较显著。由于加入合金元素的种类、数量和配比不同，金合金的性能会有很大差异。通常，铅、锑、铋、碲等元素被认为是金合金中的有害元素，它们使合金脆化，应控制其含量。工业中应用的金合金品种很多，其中应用较多的是金银合金、金铜合金、金镍合金和金钯合金。其他重要的金合金还有金铬合金、金铂合金、金锆合金和金钛合金以及金硅合金、金锗合金、金锡合金和金锑合金等。
旋压技术起源于古代制陶工艺。它是一种综合了锻造、挤压、拉件、弯曲、环轧、横轧和滚挤等工艺特点的少无切削加工的先进工艺。通常将金属简坯、平板毛坯或预制坯用尾顶顶紧在旋压机模上，由主轴带动芯棒和坯料旋转；同时旋压轮从毛坯一侧将材料挤压在旋转的芯模上，使材料产生逐点连续的塑性变形，从而获得各种母线形状的空心旋转体零件。根据旋压加工过程中的毛坯厚度变化情况，把旋压工艺分为普通旋压和强力旋压两种，即普通旋压和强力旋压。
普通旋压简称普旋。普旋过程中毛坯的厚度基本保持不变，成形主要依靠坯料沿圆周的收缩及沿半径方向上伴长不变形来实现。其主要特征是在成形过程中，可以明显看出坯料外径的变化。普通旋压的基本方式有：拉深旋压(拉旋)、缩径旋压(缩旋)和扩径旋压(扩旋)等三种。
