Description

Technical Field

[0001] This utility model belongs to the field of heat treatment cooling technology, and in particular relates to a misaligned layered cooling device for heat treatment of axles. Background Technology

[0002] In the manufacturing process of axles, the heat treatment and cooling process has a crucial impact on the performance of the axles. As a key component that bears the weight of the vehicle and the impact forces during operation, the uniformity of its internal structure, hardness, and toughness directly affect the safety and service life of the vehicle.

[0003] Traditional cooling systems have a single cooling path, making it difficult for the cooling medium to fully cover the axle surface. Especially for long axles, relying on cooling from only one side or in one direction will create a temperature gradient along the length of the axle, affecting the final heat treatment quality. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A staggered layered cooling device for axle heat treatment includes a cooling box. A fan is fixedly fitted on the inner ring of the top of the cooling box, and a stepped frame is fixedly installed inside the bottom. Several air guide pipes are installed on both the left and right sides. An air collecting hood and an air blowing hood are fixedly connected to both ends of the air guide pipes. The air collecting hood and the air blowing hood are respectively set on two adjacent steps of the stepped frame. The air guide pipes on both sides are staggered so that the air collecting hood on the left side is aligned with the air blowing hood on the right side.

[0006] As a preferred embodiment of the above technical solution, each step of the stepped frame is provided with a U-shaped air guide groove, and the air collecting hood and the air blowing hood are both adapted to the size of the U-shaped air guide groove.

[0007] As a preferred embodiment of the above technical solution, each step of the stepped frame is fixedly equipped with a C-shaped bracket, which is located above the U-shaped air guide duct.

[0008] As a preferred embodiment of the above technical solution, a second air guide pipe is fixedly installed on one side of the cooling box, and a second air collecting hood and a second air blowing hood are fixedly installed at both ends of the second air guide pipe. The second air collecting hood is located at the bottom of the stepped frame and aligned with the first air blowing hood, and the second air blowing hood is located at the top of the stepped frame and aligned with the first air collecting hood.

[0009] As a preferred embodiment of the above technical solution, both the first air duct and the second air duct are equipped with a one-way valve and a cooling coil.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses staggered air guide pipes on the left and right sides to align the left air collecting hood and the right air blowing hood, forming a cross airflow that covers the surface of the axle; combined with the segmented support structure of the stepped frame, the cooling medium can fully cover all sections of the axle, effectively eliminating temperature gradients, ensuring the uniformity of the internal structure of the axle, and improving key performance indicators such as hardness and toughness after heat treatment.

[0012] 2. The U-shaped air guide groove of the stepped frame of this utility model is compatible with the air collection hood and the air blowing hood, which can guide the airflow in a directional manner, avoid dispersion, and enhance the cooling intensity of the corresponding area of ​​the axle.

[0013] The C-shaped bracket supports the axle while reducing the contact area, minimizing obstruction to airflow, and ensuring that the cooling medium reaches the axle surface directly.

[0014] The vertical airflow circulation formed by the second air duct guides the cooling airflow from the bottom to the top, balances the cooling intensity of the upper and lower layers, constructs a three-dimensional cooling network, and further improves the overall cooling efficiency.

[0015] The cooling coils inside the air duct can pre-cool the airflow, and the one-way valve ensures the directional transmission of airflow, making the cooling process more stable and efficient, ultimately improving the heat treatment quality of the axle and extending the safety and service life of the vehicle.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the axle heat treatment staggered layered cooling device includes a cooling box 10. A fan 20 is fixedly sleeved on the inner ring of the top of the cooling box 10, and a stepped frame 11 is fixedly installed inside the bottom. Several air guide pipes 30 are installed on both the left and right sides. The two ends of the air guide pipes 30 are respectively fixedly connected to an air collecting hood 31 and an air blowing hood 32. The air collecting hood 31 and the air blowing hood 32 are respectively set on two adjacent steps of the stepped frame 11. The air guide pipes 30 on both sides are staggered so that the air collecting hood 31 on the left side is aligned with the air blowing hood 32 on the right side.

[0024] It should be noted that the cooling box 10, as the carrier of the overall cooling space, provides a closed environment for axle cooling, reducing the interference of external factors on the cooling process; the fan 20 is installed at the top, which can accelerate the air circulation in the cooling box 10, supplement cold air or enhance airflow circulation, and improve the overall cooling efficiency; the stepped rack 11 adopts a stepped structure, supporting the axle in sections along the length direction, creating conditions for layered cooling and avoiding the problem of uneven cooling caused by traditional flat placement; the air guide duct 30 is responsible for airflow transmission, the air collector hood 31 collects the cooling airflow, and the air blower hood 32 guides the airflow to the axle surface. The staggered arrangement of the air guide ducts 30 on both sides aligns the left air collector hood with the right air blower hood, forming cross airflow, ensuring that each section of the axle can be fully cooled, and eliminating the temperature gradient caused by cooling in one direction.

[0025] like Figure 1 As shown, each step of the stepped frame 11 is provided with a U-shaped air guide slot 12, and the air collecting hood 31 and the air blowing hood 32 are both adapted to the size of the U-shaped air guide slot 12.

[0026] Specifically, the U-shaped air guide slot 12 is adapted to the air collection shroud 31 and the air blowing shroud 32, which can guide the cooling airflow along a fixed path to avoid airflow dispersion and enhance the cooling of the corresponding position of the axle; at the same time, the U-shaped structure fits the arc surface of the axle, making the airflow closer to the axle and improving the cooling effect.

[0027] like Figure 1 and Figure 2 Each step of the stepped frame 11 is fixedly installed with a C-shaped bracket 13, which is located above the U-shaped air guide duct 12.

[0028] Specifically, the C-shaped bracket 13 is used to stably support the axle and prevent the axle from directly contacting the stepped bracket 11, which would affect the airflow of cooling. The C-shaped structure is adapted to the shape of the axle, which can not only ensure that the axle is placed stably, but also reduce the contact area with the axle and reduce the obstruction to cooling.

[0029] like Figure 1 and Figure 3As shown, a second air guide pipe 40 is fixedly installed on one side of the cooling box 10. At both ends of the second air guide pipe 40, a second air collecting hood 41 and a second air blowing hood 42 are fixedly installed respectively. The second air collecting hood 41 is located at the bottom of the stepped frame 11 and is aligned with the first air blowing hood 32. The second air blowing hood 42 is located at the top of the stepped frame 11 and is aligned with the first air collecting hood 31.

[0030] Specifically, the second air duct 40, the second air collector hood 41, and the second air blower hood 42 form a longitudinal airflow circulation channel, guiding the cooling airflow from the bottom of the stepped frame 11 to the top, supplementing the cooling airflow at the top, and balancing the cooling intensity of the upper and lower layers; together with the lateral cross airflow of the first air duct 30, a three-dimensional cooling network is constructed, covering the entire length of the axle.

[0031] like Figure 1 and Figure 3 As shown, both air duct 1 30 and air duct 2 40 are equipped with one-way valves and cooling coils.

[0032] It should be noted that the one-way valve prevents airflow from flowing in the reverse direction within the air duct, ensuring that the airflow is directionally transmitted along the designed path, thus ensuring the stability of the cooling direction and intensity; the cooling coil pre-cools the airflow within the air duct, reducing the airflow temperature and enhancing the cooling capacity of the airflow blowing onto the axle surface, further improving the cooling effect.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
