Description

【Technical field】 [0001] The invention belongs to the technical field of metallurgy, and in particular relates to energy-saving powder metallurgy. 【Background technique】 [0002] The powder metallurgy process mainly includes three steps. First, the main constituent materials are decomposed into powders composed of many fine particles; size of the compact; finally, the compact is sintered. [0003] Since the main material of powder metallurgy is metal powder, and the raw material is decomposed into powder, the pulverizer needs to continuously crush the raw material, causing huge power consumption and noise pollution. In the process of powder loading into the mold cavity, a single mold cavity The amount of powder required is the same, but the amount of powder injected into the mold cavity is often abnormal in the mass production of blanks. Too much powder is wasted as usual and the abnormality of the press is too small. The compact is not dense enough, and even contains gaps....
