Embodiment Construction

[0021] Put the clean air outlet 1 in the container of the vibrating finishing machine equipped with different grinding media, the vibration frequency is 35-40Hz, the vertical amplitude is 6.0-6.25mm, and the horizontal amplitude is 6.75-7.0mm. After different processing times, The surface roughness of the clean air outlet (including its internal passage 11 ) and the roughness of the internal passage were tested. Different examples were obtained, see Table 1. There is no stainless steel flying saucer in the grinding media in Examples 1-3, and stainless steel flying saucers are included in the grinding media in other embodiments. see image 3 , 4 , the central portion of the flying saucer has a central ball 2 with an outer diameter L of 3-5 mm, and the periphery of the central ball 2 has an outwardly protruding annular band 3 with a substantially triangular cross-section, and the raised height H of the annular band is 20 of the outer diameter L of the central ball. -30%. See...

Abstract

The invention provides a surface treatment method of a cleaning air inlet. The method has the advantages of uniformity in surface treatment and high efficiency, the surface roughness after treatment is within Ra0.6, and the surface roughness of an internal channel is within Ra0.4. The method comprises the steps of: placing a cleaning air inlet in a vibrating finishing machine, and grinding the surface of the cleaning air inlet by using a grinding medium, wherein the vibrating frequency of the finishing machine is 35-40Hz, the vertical amplitude is 6.0-6.25mm, and the horizontal amplitude is 6.75-7.0mm.

Description

technical field [0001] The invention relates to a surface treatment method for cleaning an air inlet. Background technique [0002] The clean air inlet is a key component of spinning. Its main function is to mechanically crush the cotton in the working chamber composed of the clean air inlet and the substrate to form a fine mixture of high-quality cotton yarn and impurities. Then, under the action of the air flow formed by the wind speed tube and the diversion block, the qualified high-quality cotton yarn and impurities are shunted out through the internal channel of the clean air inlet, and the high-quality cotton yarn is twisted into cotton thread through the follow-up mechanism. Therefore, the internal channel of this product has high requirements on surface quality, and there should be no burrs or rough areas caused by any process or operation, so as to avoid the cotton yarn sticking to block the channel and causing equipment shutdown. [0003] The original cleaning air...
