Description

Technical Field

[0001] The invention relates to the field of design of powder removal devices for metallurgical parts, and in particular to a powder removal device for forming powder metallurgical parts. Background Art

[0002] Powder metallurgy is a process that uses metal powder or a mixture of metal and non-metal powder to manufacture parts through pressing and sintering. In the production process of powder metallurgy parts, due to the processes of molding, demoulding, sintering, etc., some loose powder particles may remain on the surface of the parts, which is called "floating powder". The floating powder not only affects the appearance quality of the parts, but also may affect its performance, such as causing friction or dimensional instability during assembly. After the powder metallurgy is pressed and formed, a layer of floating powder will always be attached to the entire surface. Sintering directly will seriously affect the product quality. Therefore, the floating powder needs to be removed after pressing and forming. However, the process of removing the floating powder should not use a special process, which takes too much time. The longer the time, the less likely the floating powder will fall off, which will form surface quality defects. Usually, the floating powder needs to be blown and brushed during the automatic transportation process after pressing and forming. However, due to the tight time of the process, the floating powder blowing and brushing often leads to the problem of incomplete coverage, which will cause dead corners and affect product quality. To this end, a powder removal device for powder metallurgy parts is proposed. Summary of the invention
