Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology, and more specifically relates to a heat treatment mechanism for high-pressure oil pipes. Background Technology

[0002] High-pressure oil pipes are widely used in modern industry, especially in the automotive, aerospace, and engineering machinery sectors. These pipes typically require heat treatment processes to improve their mechanical properties and corrosion resistance. Solution brightening heat treatment is a commonly used method that combines the characteristics of solution treatment and brightening treatment, enabling the improvement of material properties while maintaining a bright surface.

[0003] When traditional heat treatment furnaces process slender oil pipes, there is often a problem of poor gas flow inside the pipe holes, which leads to an excessively long residence time of the internal atmosphere and affects the quality of heat treatment, such as localized oxidation and uneven temperature distribution on the inner wall of the hole. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat treatment mechanism for high-pressure oil pipes, which includes an inlet pipe and an outlet pipe to ensure uniform flow of protective gas within the oil pipe, thereby improving the quality of heat treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment mechanism for high-pressure oil pipes, comprising a furnace body, a support frame for placing oil pipes is provided inside the furnace body, an inlet pipe and an outlet pipe are respectively provided at both ends of the support frame, and the inlet pipe and the outlet pipe are slidably connected to the support frame, an inlet nozzle corresponding to one port of the oil pipe is provided on the inlet pipe, and an air suction sleeve corresponding to the other port of the oil pipe is provided on the outlet pipe, the inlet nozzle moves with the inlet pipe and extends into the port of the oil pipe, the air suction sleeve moves with the outlet pipe and is fitted onto the port of the oil pipe, an atmosphere circulation device is provided on the furnace body, an atmosphere outlet and an atmosphere suction port are provided on the furnace body, the atmosphere outlet and the atmosphere suction port are connected to the atmosphere circulation device, when the inlet nozzle extends into the port of the oil pipe, the other end of the inlet pipe faces the atmosphere outlet, and when the air suction sleeve is fitted onto the port of the oil pipe, the other end of the outlet pipe faces the atmosphere suction port.

[0006] Furthermore, a conical shroud is provided on the other end of both the air inlet pipe and the air outlet pipe.

[0007] Furthermore, a fixed guide rod is provided on the furnace body, and clamping blocks are provided on both the air inlet pipe and the air outlet pipe. The guide rod passes through the clamping blocks, allowing the clamping blocks to slide on the guide rod.

[0008] Furthermore, the support frame is provided with guide rails corresponding to the air inlet pipe and the air outlet pipe at both ends, and a slider is provided on the guide rail, with the air inlet pipe and the air outlet pipe connected to the slider.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by setting an air inlet pipe to receive a portion of the fresh gas discharged into the furnace body from the atmosphere outlet and guiding it into the oil pipe, and then the air outlet pipe is connected to the atmosphere suction port to generate suction, so as to discharge the gas in the oil pipe in time, thereby achieving uniform flow of gas in the oil pipe and improving the quality of heat treatment.

[0014] Reference Figure 1 The present invention will be further described below.

[0015] A heat treatment mechanism for high-pressure oil pipes includes a furnace body 1. A support frame 3 for placing oil pipes 2 is provided inside the furnace body 1. An inlet pipe 4 and an outlet pipe 5 are respectively provided at both ends of the support frame 3, and both the inlet pipe 4 and the outlet pipe 5 are slidably connected to the support frame 3. An inlet nozzle 6 corresponding to one opening of the oil pipe 2 is provided on the inlet pipe 4, and an air suction sleeve 7 corresponding to the other opening of the oil pipe 2 is provided on the outlet pipe 5. The inlet nozzle 6 extends as the inlet pipe 4 moves. Inside the inlet of oil pipe 2, the suction sleeve 7 moves with the outlet pipe 5 and is fitted onto the inlet of oil pipe 2. An atmosphere circulation device is provided on the furnace body 1. An atmosphere outlet 8 and an atmosphere suction port 9 are provided on the furnace body 1. The atmosphere outlet 8 and the atmosphere suction port 9 are connected to the atmosphere circulation device. When the air inlet nozzle 6 extends into the inlet of oil pipe 2, the other end of the air inlet pipe 4 faces the atmosphere outlet 8. When the suction sleeve 7 is fitted onto the inlet of oil pipe 2, the other end of the outlet pipe 5 faces the atmosphere suction port 9.

[0016] like Figure 1 As shown, after the oil pipe 2 is fixedly placed on the support frame 3, both the inlet pipe 4 and the outlet pipe 5 move towards the oil pipe 2. The inlet nozzle 6 on the inlet pipe 4 extends into the oil pipe 2, and the suction sleeve 7 on the outlet pipe 5 is fitted onto the opening of the oil pipe 2. At the same time, the other end of the inlet pipe 4 faces the atmosphere outlet 8, and the other end of the outlet pipe 5 faces the atmosphere suction port 9. After the solution bright heat treatment begins, the protective gas enters the furnace body 1 from the atmosphere outlet 8 and simultaneously enters the inlet pipe 4. It is then injected into the oil pipe 2 through the inlet pipe 4. The outlet pipe 5 at the other end of the oil pipe 2 absorbs the gas in the oil pipe 2. After passing through the outlet pipe 5, it is sucked out by the atmosphere suction port 9 and enters the atmosphere circulation device. This ensures that the inside of the slender oil pipe 2 can be filled with fresh atmosphere in a timely manner, avoiding poor gas flow inside the oil pipe 2 and causing the internal atmosphere to remain for too long, which would affect the quality of the heat treatment.

[0017] Specifically, the atmosphere circulation device includes a filtration mechanism, a heating mechanism, and a pressurization mechanism. The filtration mechanism filters out dust and impurities in the atmosphere, the heating mechanism heats the atmosphere to ensure the stability of the internal temperature of the furnace body 1 after it enters the furnace body 1, and the pressurization mechanism increases the flow rate and pressure of the gas to ensure the stability of the atmosphere pressure inside the furnace body 1.

[0018] like Figure 1 As shown in this example, preferably, a conical cover 10 is provided on the other end of the air inlet pipe 4 and the other end of the air outlet pipe 5.

[0019] like Figure 1 As shown in this example, preferably, the furnace body 1 is provided with a fixed guide rod 11, and the air inlet pipe 4 and the air outlet pipe 5 are both provided with clamping blocks 12. The guide rod 11 passes through the clamping blocks 12, so that the clamping blocks 12 slide on the guide rod 11.

[0020] like Figure 1As shown in this example, preferably, the support frame 3 is provided with guide rails 13 at both ends corresponding to the air inlet pipe 4 and the air outlet pipe 5, and a slider 14 is provided on the guide rail 13, and the air inlet pipe 4 and the air outlet pipe 5 are connected to the slider 14.

[0021] like Figure 1 As shown, specifically, the support frame 3 is provided with a plurality of support blocks 15 for supporting and fixing the oil pipe 2.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
