Discharge device for preparing electronic device alloy powder

Abstract

The invention discloses a discharge device for preparing electronic device alloy powder, and relates to the field of alloy powder preparation. In the discharging device, a through groove is formed inthe middle of one surface of a mounting frame, and a discharge bucket is installed in the through groove; a sealing cover is installed above the discharge bucket, and a motor is arranged at the axis of the upper surface of the sealing cover; a stirring rod is installed on a rotating shaft of the motor, and a discharge hopper is fixedly installed at the bottom of the discharge bucket; and a filterscreen mounting seat is arranged on the lower surface of the discharge hopper, and a discharge opening is formed in the bottom surface of the filter screen mounting seat. The discharge device performsstorage and discharge through the cooperation of the discharge bucket and the discharge hopper; hydraulic cylinders drive the upper and lower shaking of the discharge bucket and the motor drives thestirring rod to stir the alloy powder; the powder in the discharge bucket can be uniformly discharged, and clogging is avoided; and a filter screen is arranged at the discharge opening to screen out metal blocks with excessive particle sizes to improve the discharge quality.

Description

technical field [0001] The invention belongs to the field of alloy powder preparation, in particular to a discharge device for the preparation of electronic device alloy powder. Background technique [0002] Metal powder formed by partial or complete alloying of two or more components. Alloy powders are mainly classified by composition into iron alloy powders, copper alloy powders, nickel alloy powders, cobalt alloy powders, aluminum alloy powders, titanium alloy powders and precious metal alloy powders. [0003] Cemented carbide consists of two parts: a hard matrix and a bonding metal. Cemented carbide is an excellent tool material, mainly used in cutting tools, metal forming tools, surface wear-resistant materials and high rigidity structural components. The hard matrix is ​​made of refractory metal compounds, mainly tungsten carbide and titanium carbide, as well as tantalum carbide, niobium carbide and vanadium carbide, etc., to ensure that the alloy has high hardness a...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing powder material feeding device generally includes a lowering hopper and a lowering bucket. , under the action of its own gravity, the powder material flows into the pouring barrel from the discharge port at the lower end of the lower hopper, and then flows out from the lower end of the lower barrel, so as to realize the conveying of the powder material. In the existing powder material discharging device During the feeding process, due to the relatively poor fluidity of the powder materials, and under the action of gravity, the powder materials are easy to squeeze together, so the powder materials are easy to accumulate and bridge in the discharge hopper, thus forming a "hollow bridge". A blanking dead zone is generated, resulting in poor flow of materials, and even material blockage, which affects the normal operation of blanking
