    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.
