Abstract

The invention discloses a powder metallurgical particle vibration grading device. The powder metallurgical particle vibration grading device comprises a vibration table and is characterized in that a vibration block is arranged on the vibration table, a slope is connected to the vibration block, side plates arranged in a bilateral symmetry manner are connected to the slope, a storage platform is connected to the upper end of the slope, a surrounding plate connected with the side plates is arranged on the platform, each side plate is divided into an upper segment and a lower segment from top to bottom along the slope, the upper segments of the two side plates are close to each other downwards and gradually along the slope, the lower segment of each side plate is sequentially and at least provided with two stages of screening areas from top to bottom along the slope, the two side plates in each stage of screening area are parallel, the distance between two parallel side plates in the upper stage of screening area is smaller than the distance between the two parallel side plates in the lower stage of screening area, and the two side plates between the two stages of screening areas are gradually away from each other along the slope from top to bottom, a layering plate is connected between two parallel side plates in each stage, and the distance between the layering plate on the upper stage and the slope is larger than the distance between the layering plate on the lower stage and the slope; the side, located at the lower end of the slope, of each layering plate before the tail stage is connected with a vertical plate, and the layering plates are connected with a discharging sliding way; the device is small, exquisite and free of hole blockage.

Description

technical field [0001] The invention relates to a powder metallurgy experiment or production particle classification tool, in particular to a powder metallurgy particle vibration classification device. Background technique [0002] my country is a big industrial country. With the advancement of science and technology, my country's manufacturing industry is booming, the economy is becoming stronger and stronger, new technologies and materials are constantly emerging, and powder metallurgy materials are one of them. Powder metallurgy can make porous, semi-dense or fully dense parts, such as oil bearings, gears and other parts, which are widely used in various industries without cutting. It has unique chemical composition and mechanical and physical properties. Iron powder is widely used because of its low cost and strong practicability, which cannot be obtained by metal processing methods. The existing production process of iron powder powder products is generally to prepare ...

AI Technical Summary

Problems solved by technology

The existing production process of iron powder powder products is generally to prepare powder particles with appropriate particle size, then press them into shape, and then sinter to form parts with fixed shapes. The density and product performance after sintering are directly related to the size of powder particles. , Different products have different requirements, and powder particles of different particle sizes need to be uniformly mixed in different proportions to achieve the desired effect. Therefore, it is very important to sieve iron powder particles, especially in small batch production or experiments. The most important thing is that the existing sieving is mainly through sieve screening. Due to the small size of the iron powder powder required to be prepared, the production of the sieve is difficult, the cost is high, and it is easy to block the screen and difficult to clean. Currently, more suitable for this need Practical tools are still lacking, which still needs to be solved by technology
