Powder material homogenizing device for metal metallurgy

Abstract

The invention discloses a powder material homogenizing device for metal metallurgy. The powder material homogenizing device comprises a bottom plate, a homogenizing barrel arranged on the bottom plate, a rotating mechanism arranged above the homogenizing barrel, a moving mechanism connected to the rotating mechanism and a mixing mechanism connected to the moving mechanism. The rotating mechanism is connected with a driving part, and the bottom of the homogenizing barrel is fixed and communicated with a discharging pipe with a sealing cover; a motor is powered on to drive the rotating mechanismto move, the rotating mechanism drives the cams on the two sides to rotate through a gear set, and the moving mechanism is driven to move transversely while rotating under the action of the cams anda rotating wheel. The moving mechanism moves transversely in a reciprocating mode, the vertically-arranged mixing piece is driven by the connecting rod to rotate while moving up and down along a stabilizing piece, metal powder materials in the homogenizing barrel are evenly mixed, and compared with a mixing piece rotating at a fixed position, dead-corner-free mixing can be achieved.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a homogenizing device for powder materials used in metallurgy. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. The powder metallurgy method has similarities with the production of ceramics, and both belong to the powder sintering technology. [0003] The production process of powder includes steps such as powder preparation and powder mixing. Plasticizers such as motor oil, rubber or paraffin are usually added to improve the formability and plasticity of the powder. [0004] However, most of the current existing mixing devices mix the materials evenly by rotating the stirring blades at fixed positions, but there are gaps between two adj...

Problems solved by technology

[0004] However, most of the existing mixing devices at present mix the materials evenly by rotating the stirring blades at fixed positions, but there are gaps between two adjacent stirring blades, and the materials existing in the gaps cannot be mixed effectively.
