Example Embodiment

[0009] The embodiment of the present invention: the hyperbolic nozzle of the sandblasting machine includes an air inlet 1 and a sand inlet 2. A hyperbolic nozzle 3 is provided directly below the air valve of the air inlet 1; the inner cavity of the hyperbolic nozzle 3 is longitudinally The cross-section is a hyperbolic structure. The diameter of the top end of the inner cavity of the hyperbolic nozzle 3 is 5mm, the diameter of the bottom end is 12mm, and the length is 12mm; the hyperbolic curve is shown in formula I:

[0010] (X / 2.5) 2 +(Y / 57) 2 = 1 (I).

[0011] Due to the structure of the above-mentioned embodiment, compared with the existing straight nozzle nozzle, under the same compressed air power, the sandblasting effect is increased by 2-3 times.

Abstract

The invention discloses a hyperbolic nozzle of a sand blasting machine. The hyperbolic nozzle comprises an air inlet and a sand inlet. A hyperbolic spout is arranged under an air valve of the air inlet. The longitudinal section of an inner cavity of the hyperbolic spout is of a hyperbolic structure, the diameter of the top end of the inner cavity of the hyperbolic spout ranges from 4 mm to 6 mm, the diameter of the bottom end of the inner cavity ranges from 10 mm to 15 mm, and the length ranges from 110 mm to 130 mm. The spout part of the nozzle is improved, the inner cavity of the spout is of the specific hyperbolic structure, energy of compressed air can be effectively used for accelerating sand through the structure, accelerating efficiency can be effectively improved on the premise of not improving power of the compressed air, and the effects of saving energy and improving efficiency are achieved. The hyperbolic nozzle is simple in structure, low in cost and ideal in use effect.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a hyperbolic nozzle of a sandblasting machine. Background technique [0002] The nozzle of the sandblasting machine is an important part related to the processing quality of the sandblasting machine. The nozzle part of the existing sandblasting machine nozzle mainly adopts a straight pipe structure. Although the resistance of this structure is small, the effect of sandblasting is not very ideal due to the low acceleration efficiency. Usually, it is necessary to use a relatively high pressure compression Air is used to ensure the power of sandblasting. Contents of the invention [0003] The purpose of the present invention is to provide a hyperbolic nozzle of a sandblasting machine, which can effectively improve the sandblasting efficiency of the nozzle, save energy and improve efficiency, so as to overcome the shortcomings of the prior art. [0004] The present invention is achieved li...
