Embodiment Construction

[0032] attached figure 1 As an embodiment of the present invention, this embodiment is specifically described in conjunction with the accompanying drawings, including a silo 1, a grinding roller 2, a fixed roller 3, blades 4 and a pressure plate 5.

[0033] Wherein, the silo 1 is a cylindrical structure with an open upper end, a rotating shaft is arranged at the central axis, and a fixed roller 3 is arranged coaxially with it outside the rotating shaft. The fixed roller 3 is also a cylindrical structure, which can be hollow or solid. Structure, preferably a solid structure, the fixed roller 3 is located inside the silo 1, the lower end surface of the fixed roller 3 is coplanar with the upper surface of the bottom surface of the silo 1, and the upper end surface is fixed with a blade 4, and the blade 4 is fixed on the central axis of the silo. The number of heart ring arrays can be selected according to needs, and three blades 4 are selected in this embodiment.

Abstract

A grinding device for powder metallurgy comprises a storage bin, an extruding device and a stirring device, wherein the storage bin is used for containing metallurgic powder, the extruding device is arranged in the storage bin and used for rolling the metallurgic powder, the stirring device is arranged in the storage bin and used for stirring the metallurgic powder, and a vertical extruding device for flaking the metallurgic powder is arranged in a horizontal type and is combined with the stirring device, so that the occupied space is reduced; and moreover, once feeding can be realized, repeated rolling is carried out for formation, so that the structure of the device is simplified, and the flaking rate is increased.

Description

technical field [0001] The invention relates to a grinding device and method, in particular to a grinding device and a grinding method used in powder metallurgy. Background technique [0002] Powder metallurgy is to produce metal or use metal powder as raw material, after forming and sintering, to manufacture metal materials, composites and various types of products. It is widely used in machining tools and metal abrasive tools and other industries. At the same time, flake powder is required as a raw material. In the existing device for preparing flake powder, roller type, air cooling, rotation and other pressing processes are generally used, and a certain rolling force is formed by the rotating roller body to form a flake. powder. However, this kind of flake powder grinding device has complex structure, many processes, low efficiency, high power consumption, high cost, large floor space, and large one-time investment, resulting in high cost.
