Problems solved by technology
[0004] The device used in the above tungsten alloy powder granulation method is relatively simple. The disadvantage is that due to the inhomogeneity of the applied force, direction and speed during manual operation, the uniformity of the particle size is affected, resulting in the quality of the sintered density of the alloy. ; Secondly, the manual granulation method is labor-intensive and the productivity is low

The invention relates to a hyperbaric tungsten alloy powder granulator, which comprises a mesh sieve and a granulating groove, wherein the lower end of the granulating groove is provided with a discharging opening. The hyperbaric tungsten alloy powder granulator is characterized in that the mesh sieve is arranged in the granulating groove and the granulating groove is fixedly arranged on a machine frame; and an extruding scraper for extruding and scraping alloy powders on the mesh sieve to cause the powders to drop into the granulating groove is arranged above the mesh sieve, and the extruding scraper is connected with a driving mechanism which drives the extruding scraper to rotate. As the extruding scraper is controlled by the mechanical driving mechanism, the labor intensity is reducedand the production efficiency is improved, and the granularity and the distribution thereof of the alloy powders can are controlled to improve the evenness of the alloy powders.
Description
technical field [0001] The invention relates to an alloy powder granulation machine, in particular to a high specific gravity tungsten alloy powder granulation device. Background technique [0002] High-density tungsten alloy is an alloy based on tungsten and composed of several additive elements and a binder phase; it is usually produced by mixing, pressing and sintering by powder metallurgy. Among them, the sintering density is an important factor affecting the quality of the alloy in the powder metallurgy process, and the sintering density is closely related to the particle size and particle size distribution of the alloy powder. The alloy particle size and particle size distribution depend on the operational factors in the granulation process of the alloy powder, including manual and mechanical. [0003] At present, the alloy powder granulation device adopts a structure in which a mesh screen and an alloy powder granulation tank are combined; that is, the alloy powder g...
