Volumetric weighing and distributing device and distributing method thereof

Abstract

The invention discloses a volumetric weighing and distributing device and a distributing method thereof, and belongs to the technical field of powder metallurgy. A distributing mechanism is arranged on a working platform, a dry pressing forming die is arranged below the distributing mechanism, a weighing device is arranged above the distributing mechanism, a feeding vibration disc is arranged above the weighing device, and an ejection mechanism is arranged on the lower surface of the working platform and located below the material distributing mechanism; and the weighing device comprises a mini air cylinder, a weighing hopper, a weight sensor, a cantilever beam, a stand column, a weighing hopper bin gate and an ejector rod, the distributing mechanism comprises a distributing hopper, a distributing motor, a crank, a sliding block and a distributing guide rail, and the ejection mechanism comprises a shell, a lifting stepping sliding table, a protruding block, an ejection reset spring, aconnecting plate, a clamping jaw, a ball screw, a sliding base and an ejection plate. According to the volumetric weighing and distributing device and the distributing method thereof, powder materialswith different densities are measured in two aspects of weight and volume, so that the weight of the powder materials filled in the distributing device is accurate, guarantee is provided for subsequent powder sintering, and the quality of finished products is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a volumetric weighing and distributing device and a distributing method thereof. Background technique [0002] Powder metallurgy is the process technology of producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after pressing 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. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials.

Problems solved by technology

[0003] Before the powder is compacted, it is often necessary to evenly arrange the powder material in the molding mold. In the prior art, due to the different density of the powder material, even if the weight of the powder material meets the preset value, the mold cavity In fact, it is not filled with powder materials, which eventually leads to the raw material content in the finished product being less than the set value, which affects the quality of the finished product after sintering
