Problems solved by technology
[0002] In powder metallurgy, the metal powder and auxiliary powder are evenly mixed and then fired. If the large particle metal powder is not removed, the quality of the molded workpiece will be affected, and the metal powder and auxiliary powder are not mixed uniformly. The different proportions of metal powder and auxiliary powder will lead to different strengths of various parts of the molded workpiece, which will affect the service life of the workpiece

The invention discloses powder uniform mixing equipment for powder metallurgy. The equipment comprises a main body machine rack; a device cavity is formed inside the main body machine rack; a worm isrotationally connected between the front inner side wall and the rear inner side wall of the device cavity; a swing box is rotationally connected with the worm; a worm gear cavity is formed inside theswing box; a swing connecting rod is rotatably connected with the interior of the worm gear cavity in a left-right penetrated mode; and the section, inside the worm gear cavity, of the swing connecting rod is fixedly connected with a worm gear. According to the powder uniform mixing equipment for powder metallurgy, metal powder is directly screened, and small-particle metal powder and auxiliary powder flowing out intermittently are mixed, so that uniform mixing of the metal powder and the auxiliary powder is guaranteed; then the mixed powder is uniformly sprayed into a mold through a slidingspray head swinging in a reciprocating mode, so that the hollowness inside a metallurgical product is reduced, and the percent of pass of the metallurgical product is increased; and the large-particlemetal powder is reused after being ground, so that the utilization rate of the metal powder is increased.
Description
technical field [0001] The invention relates to the related field of metallurgical technology, in particular to a device for evenly mixing powders for powder metallurgy. Background technique [0002] In powder metallurgy, the metal powder and auxiliary powder are evenly mixed and then fired. If the large particle metal powder is not removed, the quality of the molded workpiece will be affected, and the metal powder and auxiliary powder are not mixed uniformly. The different proportions of metal powder and auxiliary powder will lead to different strengths of various parts of the molded workpiece, which will affect the service life of the workpiece. [0003] A device for evenly mixing powders for powder metallurgy described in the present invention can solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned problems, a kind of equipment for powder metallurgy uniform mixing powder is designed in this example, and a kind of equipment...
