Description

Technical Field

[0001] The utility model belongs to the field of oil removal devices, and in particular relates to an improved oil blowing device. Background Art

[0002] In the process of mechanical processing, a large amount of cutting oil is usually used to reduce friction, dissipate heat and improve cutting efficiency. However, with the completion of processing, a large amount of oil stains will remain on the surface of the product. These oil stains will not only affect the appearance quality of the product, but also have an adverse effect on the subsequent processing, such as affecting the coating, corroding the metal, etc. Therefore, removing the oil stains on the surface of the product is an important process after mechanical processing.

[0003] Traditional degreasing devices usually use a single-hole blowing method, that is, blowing the product surface through a single blowing hole to remove the surface oil. However, this method has obvious shortcomings. First, due to the limited number of blowing holes, it is impossible to fully cover the product surface, resulting in the inability to effectively remove the oil in some areas. Secondly, in order to cover the product surface as much as possible, the single-hole blowing has a large diameter and a low initial velocity of the airflow, which cannot completely remove some oil stains with strong adhesion.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0025] Reference Figures 1 to 4 ,refer to Figures 1 to 4 , an improved oil blowing device, comprising an oil blowing body, a left connecting piece 3 and a right connecting piece 4. A through hole 5 for the product to pass through is provided in the middle of the oil blowing body, an annular air passage 6 coaxial with the through hole 5 is provided in the oil blowing body, and an annular air groove 7 connected with the through hole 5 is provided on the side of the annular air passage 6 facing the through hole 5. An air inlet 8 connected with the annular air passage 6 is provided on the side of the oil blowing body. The left connecting piece 3 and the right connecting piece 4 are respectively assembled on the left and right end surfaces of the oil blowing body, and the through hole 5 passes through the left connecting piece 3 and the right connecting piece 4. The annular air groove 7 can perform 360° air blowing without dead angles on the product located in the through hole 5, can effectively remove the cutting oil on the product, reduce the impact on subsequent processing, and is conducive to improving the quality of the product.

[0026] In order to facilitate production and manufacturing, the oil blowing body is designed to be assembled in parts, and includes an air disc 1 and a cover plate 2. An annular groove is provided on one end face of the air disc 1. After the cover plate 2 is assembled with the air disc 1, the annular groove and the cover plate 2 cooperate to form an annular air channel 6; the annular groove divides the end face of the air disc 1 into an outer annular surface and an inner annular surface. After the outer annular surface and the cover plate 2 are assembled, an annular air groove 7 is formed between the inner annular surface and the cover plate 2.

[0027] In the present invention, the ratio of the width a of the annular air groove 7 to the width b of the annular groove is 1 / 20 to 1 / 10, so that when the airflow enters the annular air groove 7 from the annular air passage 6, the initial velocity of the airflow is greatly increased due to the reduction of the aperture, so as to ensure the oil blowing effect. Preferably, the ratio of the width a of the annular air groove 7 to the width b of the annular groove is 1 / 14, and this ratio setting can take into account both the oil blowing effect and the noise reduction.

[0028] Furthermore, the annular air groove 7 is biased toward one end face of the oil blowing body, and the end face is provided with a first flare 9 at the through hole 5, and the outlet of the annular air groove 7 is located on the inclined surface of the first flare 9. The first flare 9 is located on the left end face of the oil blowing body, and the left connecting member 3 is provided with a plurality of leakage grooves 11 arranged around the through hole 5, and the leakage grooves 11 connect the through hole 5 and the external environment. The end face of the left connecting member 3 used for assembly with the oil blowing body is provided with a second flare 10 at the through hole 5, and the second flare 10 and the first flare 9 are arranged oppositely. The function of this design is to collect the blown cutting oil. The blown cutting oil droplets will cover the surfaces of the first flare 9 and the second flare 10, and then gather and drip from the leakage groove 11, so as to avoid the blown cutting oil from being re-attached to the product due to air flow disturbance, and the dripping cutting oil can be recycled after being collected, which is conducive to reducing the waste of cutting oil and reducing the processing cost.

[0029] Preferably, the oil blowing body, the left connecting piece 3 and the right connecting piece 4 are made of aluminum alloy, which can effectively prevent corrosion. Among them, the material of the gas disk 1 can be 6061-O material, which has higher strength and can effectively resist the impact of high-speed airflow.

[0030] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
