Description

Technical Field

[0001] The utility model relates to the technical field of welding and cutting nozzles, in particular to a welding and cutting nozzle with an anti-overheating mechanism. Background Art

[0002] The welding and cutting nozzle, also known as a cutting nozzle or a welding torch nozzle, is a component installed at the head of a welding torch or a cutting torch. The welding and cutting nozzle is a key component in welding and cutting equipment and plays an important role in the welding and cutting processes. The welding and cutting nozzle is usually made of materials such as metal or ceramic that are resistant to high temperatures and corrosion.

[0003] During long-term use, the cutting nozzle is continuously irradiated by a high-temperature heat source, resulting in the accumulation of heat on the cutting nozzle. If the heat cannot be dissipated in time, the temperature of the cutting nozzle will gradually increase. An overheated cutting nozzle will not only cause uneven heat distribution during the cutting process, thereby affecting the stability of the cutting nozzle, but also pose certain safety hazards and is not conducive to the safe production of workers. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a welding and cutting nozzle with an anti-overheating mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A welding and cutting nozzle with an anti-overheating mechanism includes a cutting torch, a cutting nozzle, and a nut. The cutting nozzle is installed on the cutting torch through the nut. Multiple heat dissipation pipes are fixedly arranged on the nut, and all the heat dissipation pipes are located outside the cutting nozzle. A micro air pump is fixedly arranged on the nut. The output end of the micro air pump is provided with an air delivery pipe, and the other end of the air delivery pipe is communicated with an air ring, and all the heat dissipation pipes are communicated with the air ring.

[0007] In addition, preferably, multiple support columns are fixedly arranged on the nut corresponding to the heat dissipation pipes, and all the support columns are fixedly connected to one end of the heat dissipation pipes.

[0008] In addition, preferably, the other ends of the heat dissipation pipes are fixedly connected to the air ring. An air cavity is formed inside the air ring, and the air cavity is communicated with the air delivery pipe and the heat dissipation pipes.

[0009] In addition, preferably, a support ring is connected to the side wall of the heat dissipation pipe, and both the support ring and the air ring are sleeved on the cutting nozzle.

[0010] In addition, preferably, six heat dissipation pipes are arranged in an "annular" array, and multiple heat dissipation pores are formed on the side of the heat dissipation pipes facing the cutting nozzle.

[0011] In addition, a preferred structure is that the cutting nozzle is inserted into the cutting torch by means of a thread, and a nut is sleeved on the outside of the connection between the cutting torch and the cutting nozzle by means of a thread.

[0012] The beneficial effects of the present utility model are as follows: through the arrangement of the air ring and the support ring, the synchronous installation of the heat dissipation pipeline can be realized when the nut is installed. Through the arrangement of the micro air pump, the heat dissipation pipeline and the heat dissipation pores, the temperature reduction of the cutting nozzle can be realized, so as to avoid the gradual increase of the temperature of the cutting nozzle during use, thereby improving the stability and safety of the cutting nozzle during use.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figures 1-4 , a welding and cutting nozzle with an anti-overheating mechanism includes a cutting torch 1, a cutting nozzle 2 and a nut 3. The cutting nozzle 2 is installed on the cutting torch 1 through the nut 3. A plurality of heat dissipation pipelines 5 are fixedly arranged on the nut 3, and all the heat dissipation pipelines 5 are located outside the cutting nozzle 2. A micro air pump 4 is fixedly arranged on the nut 3. The output end of the micro air pump 4 is provided with an air delivery pipeline 41, and the other end of the air delivery pipeline 41 is communicated with an air ring 42, and all the heat dissipation pipelines 5 are communicated with the air ring 42.

[0020] Among them, the cutting nozzle 2 is installed on the cutting torch 1 through a nut 3, and the connection between the cutting nozzle 2 and the cutting torch 1 is mainly realized by means of thread fitting. The design of the thread enables the two to be gradually and tightly combined during rotation to form a reliable seal. The function of the nut 3 is not only to fix the cutting nozzle 2 on the cutting torch 1, but more importantly, to enhance the sealing performance between the cutting nozzle 2 and the cutting torch 1 through its tightening force. This is the prior art, so it will not be elaborated in this utility model.

[0021] Among them, a plurality of support columns 6 are fixedly arranged on the nut 3 corresponding to the heat dissipation pipes 5, and the support columns 6 are fixedly connected to one end of the heat dissipation pipes 5. Through the arrangement of the support columns 6, the fixation of the heat dissipation pipes 5 can be realized.

[0022] Among them, the other ends of the heat dissipation pipes 5 are fixedly connected to the gas ring 42. An air cavity is opened inside the gas ring 42, and the air cavity is communicated with the air delivery pipe 41 and the heat dissipation pipes 5. Through the arrangement of the gas ring 42, the gas output by the micro air pump 4 can be transmitted into the heat dissipation pipes 5, so that the heat dissipation of the cutting nozzle 2 can be realized through the heat dissipation pipes 5.

[0023] Among them, a support ring 61 is connected to the side wall of the heat dissipation pipe 5, and both the support ring 61 and the gas ring 42 are sleeved on the cutting nozzle 2. Through the sleeving of the support ring 61 and the gas ring 42, the stability of the heat dissipation pipe 5 outside the cutting nozzle 2 can be improved.

[0024] Among them, six heat dissipation pipes 5 are arranged in an "annular" array, and a plurality of heat dissipation holes 51 are opened on the surface of the heat dissipation pipes 5 facing the cutting nozzle 2. The heat dissipation pipes 5 are not tightly connected to the outer wall of the cutting nozzle 2, so the gas can be sprayed onto the outer wall of the cutting nozzle 2 through the heat dissipation holes 51, thereby increasing the air flow speed outside the cutting nozzle 2 to realize the heat dissipation of the outer wall of the cutting nozzle 2.

[0025] The cutting nozzle 2 is inserted into the cutting torch 1 through threads, and the nut 3 is sleeved on the outside of the connection between the cutting torch 1 and the cutting nozzle 2 through threads.

[0026] In this embodiment, when the user installs the cutting nozzle 2 on the cutting torch 1, the cutting nozzle 2 needs to be inserted into the cutting torch 1 through threads, and then the nut 3 only needs to be installed on the connection between the cutting torch 1 and the cutting nozzle 2 through threads, so as to realize the installation of the cutting nozzle 2. This is the prior art, so it will not be elaborated.

[0027] Furthermore, since both the support ring 61 and the gas ring 42 are fixedly connected to the nut 3, during the installation of the nut 3, both the support ring 61 and the gas ring 42 move synchronously with the nut 3. After the nut 3 is installed, both the support ring 61 and the gas ring 42 are properly sleeved on the outside of the cutting nozzle 2, so that the heat dissipation pipes 5 are also located outside the cutting nozzle 2.

[0028] Further, a battery is provided inside the micro air pump 4. The micro air pump 4 can supply air into the air delivery pipe 41. The air flow flows into the air ring 42 through the air delivery pipe 41, and then flows into each heat dissipation pipe 5 through the air ring 42. Finally, the air flow blows to the outer wall of the cutting nozzle 2 from the heat dissipation holes 51 in the heat dissipation pipe 5, thereby realizing the cooling of the outer wall of the cutting nozzle 2 to prevent the temperature of the cutting nozzle 2 from gradually rising. It should be noted that the micro air pump 4 is a prior art, so it will not be elaborated here.

[0029] In the present utility model, through the arrangements of the air ring 42 and the support ring 61, the synchronous installation of the heat dissipation pipes 5 can be realized when the nut 3 is installed. Through the arrangements of the micro air pump 4, the heat dissipation pipes 5 and the heat dissipation holes 51, the cooling of the cutting nozzle 2 can be realized to avoid the temperature of the cutting nozzle 2 from gradually rising during use, thereby improving the stability and safety of the cutting nozzle 2 during use.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
