A sample baking separator for determining the bake hardening value of steel

Abstract

This utility model relates to the field of metal material testing technology and discloses a sample baking separation device for determining the bake hardening value of steel. It includes a small frame, a large frame, and hooks. Both the small and large frames are cubic structures formed by a first steel wire. A base plate is mounted on the bottom surface of the large frame, and the small frames are placed inside the large frame with parallel width directions. The hook rod is mounted on one side of the small frame in the thickness direction. This device, through the cubic structure of the small and large frames, places multiple samples in independent spaces. The small frames can separate a single sample or a group of samples, while the large frame accommodates multiple small frames, avoiding direct contact or stacking of samples. This physical separation allows for more uniform circulation of hot air around each sample, reducing local temperature differences caused by mutual obstruction, ensuring consistent baking conditions, and laying the foundation for the accuracy of subsequent hardening value determination.

Description

Technical Field

[0001] This utility model relates to the field of metal material testing technology, and in particular to a sample baking separation device for determining the baking hardening value of steel. Background Technology

[0002] In the production and application of metallic materials, especially steel, bake hardening performance is one of the important indicators for measuring material quality, directly affecting the stability and reliability of the material during subsequent processing and use. For materials such as cold-rolled bake hardening high-strength steel, accurately measuring its bake hardening value can provide crucial information for optimizing production processes, controlling product quality, and adapting to application scenarios.

[0003] Currently, ensuring uniform heating and preventing mutual interference among multiple samples during the baking process, thereby guaranteeing the stability and consistency of test results, is a problem that needs to be solved in current testing work. Existing technologies lack specialized devices for separating samples during the baking process, which can lead to differences in baking effects due to factors such as contact, stacking, or uneven heating. This negatively impacts subsequent test results and limits the overall accuracy of bake-hardening value determination. Utility Model Content

[0004] In view of this, the present invention provides a sample baking separation device for determining the baking hardening value of steel.

[0005] Therefore, the present invention provides the following technical solution: A sample baking separation device for determining the baking hardening value of steel includes a small frame, a large frame, and a hook. The small frame and the large frame are both cubic structures formed by a first steel wire. A base plate is installed on the bottom surface of the large frame, and the small frame is placed inside the large frame. The width directions of the two frames are kept parallel. The rod of the hook is installed on the small frame, and the hook is located on one side of the thickness direction of the small frame.

[0006] Furthermore, a closed second steel wire is installed around the outer perimeter of the small frame, and the hook's rod is simultaneously fixed to two opposing second steel wires in the thickness direction of the small frame.

[0007] Furthermore, it also includes a support frame, which is a cubic structure formed by a third steel wire, with ceramic tubes installed parallel to each other on the plane of the third steel wire at the top, and gaps between adjacent ceramic tubes.

[0008] Furthermore, it also includes a fourth steel wire, on which the ceramic tube is rotatably mounted, and the two ends of the fourth steel wire are respectively mounted on two opposing third steel wires on the upper surface of the support frame.

[0009] Furthermore, the area of ​​the plane formed by the third steel wire on the upper surface of the support frame is greater than the area of ​​the lower surface of the base plate.

[0010] Furthermore, the base plate is a copper plate or an aluminum plate.

[0011] Advantages and positive effects of this utility model: The device employs a cubic structure design with small and large frames, placing multiple samples in independent spaces. The small frames can separate individual or groups of samples, while the large frames accommodate multiple small frames, avoiding direct contact or stacking between samples. This physical separation ensures more uniform hot airflow circulation around each sample, reducing localized temperature differences caused by sample shading, thus guaranteeing consistent baking conditions and laying the foundation for accurate subsequent hardening value determination.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] This invention provides a sample baking separation device for determining the bake hardening value of steel, such as... Figures 1-2 As shown, the structure includes a small frame 3, a large frame 2, and a hook 8. Both the small frame 3 and the large frame 2 are cubic structures formed by the first steel wire 7. A base plate 1 is installed on the bottom surface of the large frame 2. The base plate 1 is made of a metal plate with good thermal conductivity, such as copper or aluminum. The small frame 3 is placed inside the large frame 2, and the two are parallel in the width direction. The rod of the hook 8 is installed on the small frame 3, and the hook 8 is located on one side of the thickness direction of the small frame 3. A closed second steel wire 9 is installed around the outer perimeter of the small frame 3, and the rod of the hook 8 is simultaneously fixed to two opposite second steel wires 9 in the thickness direction of the small frame 3.

[0022] like Figures 3-4 As shown, in two adjacent small frames 3, the hook of the hook 8 of one small frame 3 is attached to the second wire 9 of the other small frame 3 near that side. Alternatively, in two adjacent small frames 3, the hook of the hook 8 of one small frame 3 is attached to the second wire 9 of the other small frame 3 away from that side.

[0023] like Figures 5-6 As shown, the system also includes a support frame 6, which is a cubic structure formed by third steel wires 10. Ceramic tubes 5 are installed parallel to each other on the plane of the third steel wires 10 at the top, with gaps between adjacent ceramic tubes 5. It also includes a fourth steel wire 4, on which the ceramic tubes 5 are rotatably mounted. The two ends of the fourth steel wire 4 are respectively mounted on two opposing third steel wires 10 on the upper surface of the support frame 6. The area of ​​the plane formed by the third steel wires 10 on the upper surface of the support frame 6 is larger than the area of ​​the lower surface of the base plate 1. The large frame 2, the small frame 3, and the support frame 6 are all formed by steel wires, resulting in a larger heating area for the sample within the baking oven and achieving a better heating effect.

[0024] Working principle: First, place the support frame 6 into the baking oven and wait for the oven to heat up. Then, place multiple samples into the small frame 3, and finally place the small frame 3 into the large frame 2. Figure 3 As shown, in the first installation method between the small frames 3, the hook 8 on the left side of the small frame 3 between two adjacent small frames 3 is hooked onto the second steel wire 9 on the left side of the small frame 3 on the right side, and so on, until the second steel wire 9 on the right side of the rightmost small frame 3 is hooked onto the first steel wire 7 of the large frame 2, thus achieving the fit between each small frame 3 and the large frame 2. This installation method results in a larger gap between adjacent small frames 3, leading to better heating of the sample. Figure 4 As shown, in the second installation method between the small frames 3, the hook 8 on the left side of the small frame 3 between two adjacent small frames 3 is hooked onto the second steel wire 9 on the right side of the small frame 3 on the right side, and so on, until the second steel wire 9 on the right side of the rightmost small frame 3 is hooked onto the first steel wire 7 of the large frame 2, so as to achieve the cooperation between each small frame 3 and the large frame 2. In this installation method, the gap between adjacent small frames 3 is slightly smaller, but more small frames 3 can be placed in the large frame 2, so as to heat more samples at the same time and improve efficiency.

[0025] Once the oven temperature reaches the required level, the large frame 2 containing the small frame 3 is placed on the ceramic tube 5 supporting the frame 6 via the base plate 1 and pushed into the oven. The sample 11 is then easily pushed into the oven for baking via the rotatable ceramic tube 5.

[0026] This specific implementation method, through optimized design of the structure and connection relationship of each component, effectively realizes the separate placement of steel samples during the baking process, ensuring the consistency of baking conditions and laying a solid foundation for the accuracy of subsequent hardening value determination.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
