Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal powder manufacturing, in particular to an ultrasonic atomization tin powder spraying machine. BACKGROUND

[0002] Metal powder refers to a group of metal particles with a size of less than one millimeter, including single metal powder, alloy powder and some refractory compound powder with metallic properties, which is the main raw material for powder metallurgy, and tin powder is also a kind of metal powder. The atomization manufacturing method of tin powder usually has gas atomization method, rotating disc centrifugal atomization method and ultrasonic atomization method. The tin powder manufactured by ultrasonic atomization method has the advantages of high purity, low oxygen content, good sphericity and uniform particle size distribution, which can meet the use requirements of some high-performance tin powder. The ultrasonic atomization method uses an ultrasonic power generator to excite an ultrasonic transducer, so that the ultrasonic tool head loaded by the transducer vibrates. The molten tin metal is atomized by ultrasonic vibration, and then the tin metal particles in the form of mist drop are cooled and solidified in the air and fall into the powder collecting cylinder, and the collected tin metal powder is obtained.

[0003] When tin powder is processed by ultrasonic atomization, the tin powder particles need to fly a certain distance in the air to cool down completely before becoming tin powder with uniform particle size. If the tin powder collides with other parts, it will deform and affect the sphericity. If the tin powder is allowed to cool in a free and scattered manner, not only will it increase the difficulty of collecting the tin powder, but also it will affect the production efficiency of the tin powder. Therefore, the ultrasonic wave can only operate at a small power, otherwise the cooling speed of the tin powder will not keep up with the discharging speed, resulting in adhesion between the tin powder, which will reduce the sphericity of the tin powder. Therefore, we propose an ultrasonic atomization tin powder spraying machine.
