Abstract: An extrusion die in a container wherein a plate is recessed in the die and is positioned between a billet to be extruded and the face of the die. On at least one of the adjacent faces of the die and plate there is a knurled surface. The region formed between the plate and the die forms a passageway for lubricant to the extrusion die so that the lubricant may aid in the extrusion of a billet. There is a passageway in the die for the introduction of lubricant to the area between the plate and the die. The knurled surface has 10 to 50 grooves per inch, and the grooves have a depth of 0.0005 to 0.02 inches. A seal may be used to seal the passageway from the interior of the container. The die and plate may be of the same metal. The lubricant conduit in the die may have an enlarged cross-section prior to joining the passageway region between the plate and the die.
Abstract translation: 在容器中的挤出模具,其中板在模具中凹陷并且位于待挤出的坯料和模具的表面之间。 在模具和板的相邻面中的至少一个具有滚花表面。 在板和模具之间形成的区域形成用于挤出模头的润滑剂的通道,使得润滑剂可以有助于挤出坯料。 在模具中有一个通道,用于将润滑剂引入板和模具之间的区域。 滚花表面每英寸有10至50个凹槽,凹槽的深度为0.0005至0.02英寸。 密封件可用于将通道从容器的内部密封。 模具和板可以是相同的金属。 模具中的润滑剂导管可以在接合板和模具之间的通道区域之前具有扩大的横截面。
