Description

Water jet nozzle structure capable of prolonging service life

The present invention relates to a "waterjet nozzle structure that can prolong the service life", and relates to a structural technician in which a multi-angle change is compounded inside a nozzle in a waterjet cutting device.

Due to the advancement of technology, the development of sophisticated waterjet cutting technology has been widely used. The principle of waterjet cutting technology is to pressurize water through an ultra-high pressure supercharger, causing the pressure of the water to be pressurized to at least tens of thousands of pounds, and then let the high-pressure water be ejected through a small nozzle having a diameter of only about 0.004 inches, so that each can be produced. The ultra-high pressure high-speed water column of about 3,000 inches in seconds can be used for cutting various materials. In practice, the industry may add high-hardness fine abrasives to water as needed to increase its cutting ability.

Cutting with a water jet has the following advantages:

First, the cutting with a water knife, the cutting surface is quite flat and smooth, so no need to process the smoothing.

Second, the water knife is used for cutting, and almost no heat is generated during the operation, so that unintended changes in the physical properties of the material to be cut can be avoided.

Third, the water knife is used for cutting, and almost no dust is generated during the operation.

Fourth, it can be combined with computer control for high-precision cutting.

In the existing waterjet equipment, the quite critical nozzle structure is made of diamond material. Because the nozzle needs to withstand the impact and pressure of the ultra-high pressure water column, only the diamond material with high hardness is most suitable. Referring to the first figure, the nozzle 1 is opened in the body 10, and the nozzle 1 includes a water inlet 11 and a water outlet 12 with a pipe body 13 therebetween. In the conventional structure, the advance The end edge of the nozzle 11 is formed with a non-arc-shaped ring portion 14, and the ring portion 14 has a sharp or square angle. The structure of the ring portion 14 has been extended for many years, and no other industry has been researched and improved. The conventional nozzle 1 structure has a limited service life and is susceptible to damage when the water flow is sucked back. The creators of this case believe that with the development of science and technology and the growth of knowledge, the structure of various products should have progress. After searching the domestic and foreign patent databases, the creators found that the nozzle structure used in the waterjet equipment has no better and more ideal predecessor. Through continuous experimentation and exploration, the creator discovered that the conventional nozzle structure and the non-arc angle of the ring side at the inlet (ie, the ring portion 14) are not ideal designs, which would limit the service life of the nozzle.

In view of this, the creator has carried out numerous experiments and researches on the structure of the nozzle, constantly changing the structural design, and finally found that the structure is more ideal than the conventional one, so the present case arises.

The main purpose of the novel "water jet nozzle structure for prolonging service life" is to improve the nozzle structure in the water jet cutting device, and the improvement objective is to achieve an extended service life and improve structural stability.

In order to achieve the above object, the specific content of the present invention is: designing a nozzle structure, which is formed between the bodies, and includes a water inlet and a water outlet, which are provided with an arc-shaped torus and a first ring. The surface and the second torus, wherein the arcuate torus has a special lead angle and a truncated angle relationship with the first torus. Therefore, the composite structure design of the present case can not only increase the stability of the structure, but also effectively extend the service life of the nozzle.

With regard to the novel "water jet nozzle structure which can prolong the service life" and the effects thereof, the preferred embodiment of the present invention will be described in detail below.

Referring to the second figure, in the present invention, the structure of the water jet nozzle which can extend the service life, the nozzle 2 is disposed between the bodies 20, and the nozzle 2 includes a water inlet 21 and a water outlet 22; The water nozzle 21 ends to the water outlet 22 end, and the inner edge thereof is provided with a composite inner wall body 3, which is arranged in sequence: an arcuate annular surface 31, a first annular surface 32 and a second annular surface 34.

The arcuate annular surface 31 has a cross-sectional angle structure; and the first annular surface 32 is connected under the arcuate annular surface 31; the angle of inclination of the arcuate annular surface 31 and the first annular surface 32 is oriented toward The nozzle 21 is inclined.

The second annular surface 34 is disposed under the first annular surface 32 and adjacent to the water outlet 22, and the inclined angle of the second annular surface 34 is inclined toward the water outlet 22 end, and the second annular surface 34 and the second annular surface 34 At the junction of a toroid 32, there is a divider ring 33.

Please cooperate with the third figure, the arcuate annulus 31 and the first annulus 32 may have a special relationship. The length of the arcuate annulus 31 together with the length of the first toroidal surface 32 can be A in the horizontal direction of the drawing; and the length of the arcuate torus 31 together with the length of the first toroid 32 is The vertical distance of the line view can be B; if the horizontal straight line spacing between the separation rings 33 is C, the creator defines a formula as: (A+B)÷C=constant. With the aforementioned formula defined by the creator, the values of A, B, and C can be optimally changed as needed. value.

According to the structure of the conventional annular portion 14 of the first figure, the arcuate annulus 31 and the first toroidal surface 32 of the present embodiment are smooth and round. When the water column passes, it is obviously not damaged, and naturally it is better than the conventional ring portion 14 of the first figure; therefore, the case can effectively extend the service life of the nozzle 2.

Although the case only changes the shape and structure of the inner wall surface of the nozzle, the effect caused by the change is not expected. Therefore, the case should be considered as not easy to complete, and it is progressive.

In summary, the novel "waterjet nozzle structure that can prolong the service life" is indeed utilized in the industry, has not been seen in publications or publicly used before the application, and is not a technology known to the public. Furthermore, this case effectively solves the long-standing problems in the prior art and achieves the long-term needs of relevant users and consumers. It is proved that the new model cannot be easily completed. The case is in full compliance with the requirements of "industry useability", "novelty" and "progressiveness" as stipulated in the Patent Law. The patents are submitted in accordance with the law, and the Bureau is invited to conduct a detailed investigation and to approve the patent as soon as possible to protect the wisdom of the applicant. Property rights, encourage innovation.

The present invention is described by the foregoing embodiments, but it is to be understood that the form and details may be varied without departing from the spirit of the invention, and will be understood by those skilled in the art. The preferred embodiment of the present invention is only one of the ways in which the present invention can be implemented in a specific manner, but is not limited thereto, and should be defined in the scope of the appended patent application.
