Description

一种金属挤压攻丝液
技术领域
本发明属于润滑材料领域，具体涉及一种金属挤压攻丝液。
背景技术
金属挤压攻丝是用特定的丝锥压入金属套管内在内壁形成螺纹，制成管线固定连接件。其特点是冷挤压变形加工，压力和摩擦力都非常大，要求润滑剂能够在变形区内仍然能够形成坚固的油膜起润滑作用，使攻丝顺利地进行，因此要求攻丝剂具有极强的极压抗磨性能。
根据金属挤压攻丝加工的特点，要求其挤压攻丝的工件为无屑挤压攻丝，金属挤压攻丝后的工件要求极压润滑满足要求的同时表面清洁、安全和环保等。随着紧固件行业的发展，无屑攻丝工艺加工时，传统的攻丝油存在的闪点低(35～110℃)的缺点，基本为易燃和可燃型产品；清洗性能不好，加工出来工件表面大量的油泥附着物；冷却性差，攻丝加工时会出现一定的油雾；极压性不好，无屑攻丝时攻丝油由于过润滑极压性不够，导致效率低。攻丝油不能兑水使用，损耗大，使用成本高，对环境不友好。市场上常见的全合成水溶性产品多为磨削加工产品，该产品其极压性和润滑性一般，只能满足普通的磨削和车削等轻负荷的加工。
因此，需要开发一种金属挤压攻丝液，该攻丝液环保且攻丝效率高。
