摘要： The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article.A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers. After applicaiton, the lubricant and coolant are separated, the lubricant filtered to remove debris, stored, and then reinjected to provide lubrication for the process.
摘要翻译：本发明包括用于润滑和冷却工件，模具或熨烫环的装置和方法，以及在工件与这种模具或熨烫环之间的界面处冲压和冲压成型工件到中空的封闭端圆柱形制品中的装置和方法。将润滑剂液相注入冷却剂液相以在施加到金属 - 工具界面之前形成“分散体”。将润滑剂作为分散体提供在冷却剂液相而不是乳液中提供了几个优点。可以改变润滑剂的量和润滑剂注入的时间以控制润滑性，从而控制摩擦。本发明通过在熨烫模具上具有较高的润滑性（低摩擦）和较低的冲压表面上的润滑性（高摩擦），可以实现熨烫过程中的差动摩擦。对于用于生产封闭端中空体容器的特定金属成型工艺，可以控制润滑和冷却。在应用之后，润滑剂和冷却剂被分离，润滑剂被过滤以除去碎屑，储存，然后再注入以提供该过程的润滑。
