Metal powder grinding device

Abstract

The invention discloses a metal powder grinding device which comprises a shell (1) and a grinding block (2) arranged in the shell (1). The grinding block (2) comprises an upper grinding block (21), amiddle grinding block (22) and a lower grinding block (23), the middle grinding block (22) is fixedly arranged in the middle of the shell (1), a fixedly-connected first driving motor (3) is arranged at of the upper end of the shell (1) to correspond to the upper grinding block (21), and a driving shaft of the first driving motor (3) is fixedly connected with the upper grinding block (21). A seconddriving motor (4) is arranged at the lower end of the shell (1) to correspond to the lower grinding block (23), and a driving shaft of the second driving motor (4) is fixedly connected with the lowergrinding block (23); the middle grinding block (22) respectively corresponds to the upper grinding block (21) and the lower grinding block (23) to form the communicated grinding channels (5). The grinding device has the advantages that the grinding channels are adjustable, the grinding efficiency is improved, the grinding quality of the metal powder is guaranteed, and the service life of the grinding device is prolonged.

Description

technical field [0001] The invention belongs to the field of metal powder processing, and in particular relates to a metal powder grinding device. Background technique [0002] Metal powder refers to a group of metal particles with a size less than 1mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties, and is the main raw material for powder metallurgy. With the development trend of superalloys, the degree of alloying of superalloys is getting higher and higher, that is, the materials that make up superalloys have developed from 3 to 5 types to 3 to 15 or even more. In this case, the traditional Deformed superalloys and cast superalloys have been difficult to meet the requirements of use, so iron-based powder metallurgy, cobalt-based powder metallurgy, and nickel-based powder metallurgy have been developed. [0003] Powder metallurgy needs to grind the metal into powder, usually using a grinder to grind the metal. ...

AI Technical Summary

Problems solved by technology

Most of the existing grinding machines use a pair of grinding blocks to grind metal. If the grinding surface of the grinding block is partially damaged, it will easily affect the grinding quality of the metal powder.

At the same time, when the grinder is used for a period of time, the grinding accuracy will decrease, and the grinder cannot adjust the grinding channel between the grinding blocks, thereby reducing the service life of the grinder
