It can be used for pipelines, thermal equipment, machinery, oil and gas drilling, containers, chemical industry, and other special applications.

[0003] When processing round tubes, processes such as cutting and grinding are required. During these processes, in order to improve lubrication and reduce temperature, the surface of the round tube workpiece is often sprayed with oil. However, current oil spraying equipment often sprays oil directly through an air valve, which results in a large amount of oil being used, uneven oil distribution, and splashing, affecting the processing of round tubes.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a multi-station oil spraying device for round tube processing. By setting an air blowing valve and an oil spraying valve, when the device is in use, oil is sent to the air blowing nozzle at the front end of the oil spraying valve through the air blowing valve. Then, the oil sent into the air blowing nozzle is sprayed out through the oil spraying valve to form a mist of oil.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a multi-station oil spraying device for round tube processing, including a rectangular device box 1, a mounting bracket 2 is horizontally fixedly connected to the rear part of the lower surface of the inner cavity of the device box 1 along its length direction, a plurality of air blowing valves 3 are fixedly connected to the upper surface of the mounting bracket 2 along its length direction, a front mounting strip 4 and a rear mounting strip 5 are fixedly connected to the front part of the lower surface of the inner cavity of the device box 1 along its length direction, and a plurality of oil spraying valves 6 are fixedly connected between the front mounting strip 4 and the rear mounting strip 5 along their respective length directions;

[0020] The front mounting strip 4 has a plurality of through holes 7 that are transversely opened on its front end surface, each corresponding to a plurality of fuel injection valves 6. The outlets of the plurality of fuel injection valves 6 extend into the interior of the through holes 7, and fuel injectors 10 are transversely fixedly connected to the front ends of the plurality of through holes 7.

[0021] The upper surface of the front mounting strip 4 is vertically fixedly connected with multiple air nozzles 9, which correspond to multiple through holes 7 respectively. The top of each of the multiple through holes 7 is vertically provided with a connecting hole 8 that communicates with the air nozzle 9.

[0022] In this embodiment, when the device is in use, oil is supplied to the air nozzle 9 at the front end of the oil injection valve 6 through the air blowing valve 3, and then the oil supplied to the air nozzle 9 is sprayed out through the oil injection valve 6 to form a mist of oil. In this way, the amount of oil used can be controlled while ensuring the coverage area of ​​the sprayed oil and the uniformity of the sprayed oil, thereby improving the efficiency of round tube processing.

[0023] The middle part of the inner cavity of the through hole 7 narrows inward, and the entire through hole 7 has a structure that is thick at both ends and thin in the middle. The connecting hole 8 is connected to the thinner part in the middle of the through hole 7. When the gas sprayed from the fuel injection valve 6 passes through the thinner part in the middle of the through hole 7, it will be accelerated under the action of pressure. When it passes through the thinner part, it will spread outward. The oil entering this part from the air nozzle 9 will be dispersed by the air in this moving state to form a mist of oil that is sprayed outward.

[0024] Furthermore, the multiple fuel injection valves 6 correspond to the multiple air blowing valves 3 respectively.

[0025] In this embodiment, the multiple fuel injection valves 6 and the multiple air blowing valves 3 correspond to each other and can realize independent operation of multiple stations.

[0026] Furthermore, a plurality of junction boxes 12 are provided on one side of the lower surface of the inner cavity of the device box 1.

[0027] In this embodiment, the junction box 12 is used to protect the connection lines in the device.

[0028] Furthermore, the front surface of the device box 1 is provided with a plurality of oil injection holes 11 that are coaxial with and correspond to a plurality of oil injectors 10.

[0029] In this embodiment, the oil sprayed from the injector 10 will be sprayed outward through the injection hole 11.

[0030] Furthermore, a rubber sealing ring is fixedly connected to the outer surface of the outlet end of the fuel injection valve 6, and the outer surface of the rubber sealing ring is interference-fitted with the inner surface of the through hole 7.

[0031] In this embodiment, the sealing effect between the fuel injection valve 6 and the through hole 7 can be ensured by using a rubber sealing ring, thereby ensuring the fuel injection stability of the device.

[0032] The working principle and usage process of this utility model are as follows: After the utility model is installed, when the device is in use, oil is supplied to the air nozzle 9 at the front end of the oil injection valve 6 through the air blowing valve 3. Then, the oil supplied to the air nozzle 9 is sprayed out through the oil injection valve 6 to form a mist of oil. In this way, the amount of oil used can be controlled while ensuring the coverage area of ​​the sprayed oil and the uniformity of the sprayed oil, thereby improving the efficiency of round tube processing.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
