Forming die for isostatic pressing formed graphite barrel material and machining method for isostatic pressing formed barrel-shaped graphite
The invention discloses a forming die for an isostatic pressing formed graphite barrel material and a machining method for isostatic pressing formed barrel-shaped graphite, and relates to the technical field of isostatic pressing formed graphite machining. The die comprises a die steel barrel, a plastic bag, an inner core barrel, a base, a supporting ring and a vacuumizing pipe, wherein the diameter of the inner core barrel is less than the diameter of the die steel barrel and the diameter of the plastic bag, the plastic bag and the inner core barrel are installed on the base, the base is arranged at the bottom of the lower end of the die steel barrel in a sleeving mode, the plastic bag is laid in a gap between the inner core barrel and the die steel barrel, the vacuumizing pipe communicates with the interior of the plastic bag, and the supporting ring is installed at an opening in the inner side of the plastic bag in a sealed mode for vacuumizing. The method comprises a plurality of steps. The forming die for the isostatic pressing formed graphite barrel material and the machining method for the isostatic pressing formed barrel-shaped graphite have the advantages that the large-diameter barrel material can be produced in batches, the interior of a green body is optimized to be free of structural defects, the quality is good, and the isotropy degree is high.
本发明公开了一种等静压石墨筒料成型模具及等静压筒形石墨加工方法，涉及等静压石墨加工技术领域，本发明包括一种等静压石墨筒料成型模具和一种等静压筒形石墨加工方法，所述模具包括模具钢桶、胶袋、内部芯桶、底座、支撑环以及抽真空管，所述内部芯桶的直径小于模具钢桶和胶袋的直径，所述胶袋和内部芯桶安装在所述底座上，所述底座套装在模具钢桶下端底部，所述胶袋敷设在内部芯桶和模具钢桶之间的间隙内，所述抽真空管与胶袋的内部连通，所述支撑环密封安装在胶袋的内侧开口处封口进行抽真空；所述方法包括多个步骤，本发明具有能够批量生产出大直径的筒料,优化生坯内部无结构缺陷、质性好，各向同性度高等优点。
