Abstract

The utility model discloses a copper nozzle for laser cutting equipment, which comprises a main body part, wherein a cavity for airflow circulation is arranged in the main body part, and a curved surface for enhancing the airflow velocity is arranged in the cavity; because the setting of curved surface can have a pressurization process to original gas flow, and then increases its gas flow rate, the same venthole then can use littleer atmospheric pressure to play the effect of economizeing gas, the increase of gas flow rate also makes the aperture of the gas outlet of main part can reduce so make the cutting hole attenuate again simultaneously, promotes cutting accuracy, so that the quality of product obtains improving. Therefore, the utility model is worthy of popularization and application.

Description

Copper nozzle for laser cutting equipment

Technical Field

The utility model relates to the technical field of laser cutting equipment, in particular to a copper nozzle for laser cutting equipment.

Background

As shown in figure 1, in the cutting process of the existing copper nozzle, because the air flow is gentle, iron slag sometimes passes through the air outlet and is reflected to the inside of the copper nozzle, so that the cutting precision, the cutting effect and the service life of the copper nozzle are influenced, and the service life of the existing copper nozzle is about 2 days under the common condition.

In addition, the iron slag is reflected back into the copper nozzle by the reverse airflow, and the lower protective lens is damaged. And current copper mouth air current is mild, often has reverse air current to flow back through the venthole among the cutting process and gets into the nozzle the inside, influences new gas flow direction to influence cutting effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a copper nozzle for laser cutting equipment, which solves the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a copper mouth that laser cutting equipment used which characterized in that: the air flow-enhancing device comprises a main body part, wherein a cavity for air flow circulation is formed in the main body part, and a curved surface for enhancing the air flow speed is arranged in the cavity.

As a preferred technical scheme of the utility model: the curved surface is arranged at the upper end of the cavity.

As a preferred technical scheme of the utility model: the radius of the curved surface is 4-5 mm.

As a preferred technical scheme of the utility model: the radius of the curved surface is 4.69 mm.

By adopting the technical scheme, the utility model has the beneficial effects that: 1. the curved surface can be used for pressurizing the original gas flow, so that the gas flow rate is increased, the same gas outlet can use smaller gas pressure, the gas-saving effect is achieved, and the aperture of the gas outlet of the main body part can be reduced due to the increase of the gas flow rate, so that the cutting hole is thinned, the cutting precision is improved, and the quality of a product is improved;

2. because utilize the curved surface to realize the enhancement of air current velocity of flow, so make impurity be difficult to get into the copper mouth inside, also can stabilize the flow direction of air current simultaneously, so make the life of the device improve 40% -50%, for the life-span of current copper mouth two days, the life of the device can prolong to four to five days.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model. In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "upper surface", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 2, an embodiment of the present invention: the utility model provides a copper mouth that laser cutting equipment was used, includes main part 1, just main part 1's inside is used for the cavity 3 of air current circulation, just the inside of cavity 3 is equipped with the curved surface 2 that is used for strengthening the air current velocity of flow.

The curved surface 2 can be used for pressurizing the original gas flow, so that the gas flow rate is increased, smaller gas pressure can be used for the same gas outlet, the gas-saving effect is achieved, and meanwhile, the aperture of the gas outlet of the main body part 1 can be reduced due to the increase of the gas flow rate, so that the cutting hole becomes thin, the cutting precision is improved, and the quality of a product is improved;

simultaneously owing to utilize curved surface 2 to realize the enhancement of air current velocity of flow, so make impurity be difficult to get into the copper mouth inside, also can stabilize the flow direction of air current simultaneously, so make the life of the device improve 40% -50%, for the life-span of current copper mouth two days, the life of the device can prolong to four to five days.

Further, the curved surface 2 is arranged at the upper end of the cavity 3.

Furthermore, the radius of the curved surface 2 is 4-5 mm.

Specifically, the radius of the curved surface 2 is 4.69 mm.

In summary, the diameter of the air outlet of the existing copper nozzle is usually 1.2 mm, and the device has the function of enhancing the flow rate of the air flow, so that the diameter of the air outlet of the device can be reduced to 1.0 mm, and the energy-saving effect is achieved.

Under the same high-precision cutting condition before improvement, if a plate with the diameter of more than 0.5 is cut, a copper nozzle with the diameter of 1.5 is used for cutting, but the cutting lines become thick due to the increase of the diameter of the hole, so that the section is influenced, and if a cutting nozzle with the diameter of 1.2 is used, the cutting is unstable due to the smooth flow rate of gas, so that the slag adhering phenomenon is caused; after improvement, the copper nozzle with the aperture of 1.2 can achieve the cutting effect due to the fact that the gas flow rate is increased.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
