[0001] This utility model relates to the field of production technology of isostatic graphite workpieces, and in particular to a device for simultaneous internal and external processing of ultrafine powder isostatic graphite tubes. Background Technology
[0002] In the production process of ultrafine powder isostatic graphite workpieces, asphalt is often used as a binder for aggregates. Therefore, asphalt residue and other impurities from aggregates often appear on the surface of ultrafine powder isostatic graphite workpieces, which need to be cleaned.
[0003] Impurities on the surface of ultrafine powder isostatically pressed graphite workpieces can be removed by scraping with a scraper. However, the pipe structure contains an inner wall and an outer wall, requiring separate scraping of impurities on the inner and outer walls. This process is cumbersome, and the inner wall space is small, making the operation inflexible. Therefore, improvements are needed. Utility Model Content

[0011] The front of the casing is provided with a door panel, and the door panel is provided with a transparent observation window.

A second spring is provided on the second screw rod between the second blade holder and the second cantilever, and a second nut is provided on the second screw rod above the second cantilever.
[0015] The beneficial effects of this utility model are as follows: A device for synchronously processing the inner and outer surfaces of ultrafine powder isostatic graphite tubes places the ultrafine powder isostatic graphite tubes into the machine housing, and supports and drives the rotation of the ultrafine powder isostatic graphite tubes through rollers, thereby improving the level of automation.
