Abstract
Description
Technical Field
[0001] This application relates to the field of welding processing technology, and in particular to a wear-resistant strip welding structure. Background Technology
[0002] In existing technologies, large-area welding creates a significant heat-affected zone on the substrate, which may alter the substrate's microstructure and properties. This is especially problematic for heat-sensitive materials, potentially leading to a decrease in overall substrate hardness or the formation of cracks. Furthermore, the heat generated during welding makes components prone to warping, bending, and other deformations, particularly thin plates or long workpieces. Severe deformation can negatively impact the workpiece's performance.
[0003] At the same time, after large-area welding, high stress will remain inside the component. This stress will become a fatigue source for the component, which will reduce the service life of the component during long-term use and eventually cause the component to fail.
[0004] Furthermore, the method of applying a large-area wear-resistant layer by welding is relatively expensive in terms of both material and processing costs, especially when using expensive alloy materials as the wear-resistant layer, which further increases the overall cost burden. In addition, the large-area welding method is time-consuming and has low production efficiency. It also faces the problem that once the wear-resistant layer is worn or damaged, the repair work is complicated and may even require the entire component to be scrapped and remade. Utility Model Content
[0005] This application provides a wear-resistant belt welded structure to solve the existing technical problems caused by large-area welding of wear-resistant layers, such as large heat-affected zone, severe deformation, high residual stress, high cost, low production efficiency, and difficult repair operations.
[0006] In a first aspect, this application provides a wear-resistant tape welding structure, comprising: a substrate and a wear-resistant tape disposed on the substrate, wherein a portion of the outer surface of the substrate is configured as a welding position, and the wear-resistant tape is welded to the welding position in a strip-like structure.
[0007] Furthermore, the wear-resistant strip adopts several annular structures that are arranged around the welding position of the substrate, and the annular structures surround the outer periphery of the substrate.
[0008] Furthermore, the wear-resistant strip adopts several parallel and equidistant spiral structures arranged on the welding positions of the substrate, with adjacent spiral structures surrounding the outer periphery of the substrate.
[0009] Furthermore, the substrate is provided with a plurality of cavities, and the wear-resistant strip is disposed around the perimeter of the cavities.
[0010] Furthermore, the substrate is provided with a plurality of cavities, and the wear-resistant strip is disposed on the side of the cavities.
[0011] The technical solutions provided in this application have the following advantages compared with the prior art:
[0012] 1. Small heat-affected zone: Because the wear-resistant strip is only set in a specific area, the heat impact on the substrate is effectively reduced through the strip structure of the wear-resistant strip, thus avoiding changes to the overall microstructure and properties of the substrate;
[0013] 2. Controllable deformation: Compared with large-area welding, the heat applied to the strip structure wear-resistant strip is more concentrated and less, which greatly reduces the possibility of overall deformation of the substrate. It is especially suitable for substrates with complex shapes or high dimensional accuracy requirements.
[0014] 3. Low residual stress: The strip structure reduces the residual stress generated during welding, thus lowering the risk of fatigue cracks in the components during use;
[0015] 4. High material utilization rate: Only the parts that need to be strengthened are treated, which can save expensive alloy materials and reduce production costs;
[0016] 5. High processing efficiency: The strip-shaped wear-resistant belt can usually be processed quickly by automated equipment, which can effectively improve the overall production efficiency and reduce the error caused by manual intervention.
[0017] 6. Easy to repair: If a certain strip of wear-resistant tape is worn or damaged, only that part needs to be repaired or replaced, without replacing or reprocessing the entire base material component;
[0018] 7. High flexibility: Wear-resistant belts of different widths, spacings and shapes can be designed according to actual needs to adapt to different working conditions and load conditions. Attached Figure Description

[0031] To address the problems of existing technologies, such as large heat-affected zones, severe deformation, high residual stress, high cost, low production efficiency, and difficult repair operations caused by large-area welding of wear-resistant layers, this application provides a wear-resistant strip welding structure that enables processing of the wear-resistant strip only in specific areas, reducing the thermal impact on the substrate and effectively avoiding changes to the overall microstructure and properties of the substrate.
[0032] Please refer to Figure 1 The present application provides a wear-resistant strip welding structure, including: a substrate 1 and a wear-resistant strip 2 disposed on the substrate 1. A portion of the outer surface of the substrate 1 is configured as a welding position 11, and the wear-resistant strip 2 is welded to the welding position 11 in a strip structure.
[0033] By using only specific areas of the substrate 1 requiring reinforcement as welding points 11, and welding the wear-resistant strip 2 to these points while leaving other areas of the substrate 1 untouched, the wear-resistant strip 2 is placed only at the welding points 11. This effectively reduces the thermal impact on the overall substrate 1, ensuring its microstructure and performance. Compared to the large-area welding method used in existing technologies, the strip-shaped wear-resistant strip 2 requires fewer welding points, resulting in lower heat generation during welding and shorter welding time. Furthermore, it allows for more concentrated heat generation, significantly improving welding efficiency and reducing the risk of overall deformation of the substrate 1 due to heat. This effectively controls the overall deformation of the substrate 1, making it particularly suitable for components with complex shapes and high dimensional accuracy requirements. Meanwhile, since the wear-resistant belt 2 is welded only in certain areas, welding materials can be saved, effectively reducing production costs. In addition, when repairing, only the wear-resistant belt 2 needs to be repaired or replaced, without needing to treat the entire substrate 1, effectively reducing production and maintenance costs, thus better meeting the needs of effective cost control.
[0034] Wear-resistant strips 2 with different widths, spacings, and shapes can be used to meet different working conditions and load conditions, depending on the specific requirements. The following embodiments illustrate different wear-resistant strips 2:
[0035] I. In the first embodiment provided in this application, please refer to Figure 1 The wear-resistant band 2 comprises several annular structures arranged around the welding positions 11 of the substrate 1, with the annular structures surrounding the outer periphery of the substrate 1. In this embodiment, wear-resistant bands 2 of the same width can be used, and the wear-resistant bands 2 are evenly spaced at the welding positions 11 of the substrate 1 to improve the wear resistance at the corresponding positions of the welding positions 11. Since the wear-resistant band 2 is welded only to the parts that need to be reinforced, the heat generated during the welding process is concentrated in the area of the welding position 11, preventing other parts of the substrate 1 from being affected by heat and thus avoiding overall deformation of the substrate 1, which would prevent the substrate 1 from failing to meet the normal working conditions of the component.
[0036] In this embodiment, a wear-resistant band 2 with a narrower annular structure is used. Each set of wear-resistant bands 2 wraps around the radial direction of the substrate 1, thereby effectively reducing the welding area between each set of wear-resistant bands 2 and the substrate 1, reducing the overall welding amount, and concentrating the heat and stress generated by welding on the wear-resistant bands 2. The small area of the wear-resistant bands 2 also results in relatively small deformation of the welding position 11 of the substrate 1 corresponding to the wear-resistant bands 2, thus ensuring that the stability of the overall structure is not affected.
[0037] II. In the first embodiment provided in this application, please refer to Figure 2 The wear-resistant band 2 comprises several parallel, equidistant spiral structures arranged on the welding positions 11 of the substrate 1, with adjacent spiral structures surrounding the outer periphery of the substrate 1. In this embodiment, wear-resistant bands 2 of the same width can be used, and the wear-resistant bands 2 are arranged at equal intervals on the welding positions 11 of the substrate 1 to form a spiral structure, thereby improving the wear resistance at the corresponding positions of the welding positions 11. Since the wear-resistant band 2 is welded only to the parts that need to be reinforced, the heat generated during the welding process is concentrated in the area of the welding position 11, preventing other parts of the substrate 1 from being affected by heat and thus avoiding overall deformation of the substrate 1, which would prevent the substrate 1 from failing to meet the normal working conditions of the component.
[0038] In this embodiment, a wear-resistant belt 2 with a certain width and annular structure is used. Each set of wear-resistant belts 2 is inclined at a certain angle to the axial direction of the substrate 1 to form a spiral structure. This effectively reduces the welding area between each set of wear-resistant belts 2 and the substrate 1, reduces the overall welding amount, and concentrates the heat and stress generated by welding onto the wear-resistant belts 2. Through the spiral distribution of wear-resistant belts 2, the deformation of the substrate 1 caused by heat or stress is applied to the spiral structure, effectively dispersing the effects of deformation and stress, thus ensuring that the stability of the overall structure is not affected.
[0039] III. In the first embodiment provided in this application, please refer to Figure 3 The substrate 1 has a plurality of cavities 3, and the wear-resistant strip 2 is disposed around the perimeter of the cavities 3. In this embodiment, the wear-resistant strip 2 with a certain width is disposed around the perimeter of the cavities 3, thereby providing high structural strength to the outer perimeter of the cavities 3. At the same time, the area heated during the welding process can be concentrated on the outer perimeter of the cavities 3, thereby avoiding the impact of heat on the structure and performance of the cavities 3. This ensures that the assembly state between the cavities 3 on the substrate 1 and other structures is not affected, and guarantees the normal assembly function of the cavities 3.
[0040] IV. In the first embodiment provided in this application, please refer to Figure 4 The substrate 1 has a plurality of cavities 3, and the wear-resistant strip 2 is disposed beside the cavities 3. In this embodiment, wear-resistant strips 2 with the same width can be equidistantly disposed beside the cavities 3 at equal intervals, thereby concentrating heat and stress in the non-cavity 3 locations. This avoids the service life problems caused by deformation of the substrate 1 due to heat or stress occurring in the cavity 3 area, effectively ensuring the stability of the assembly state between the cavity 3 and other structures, and ensuring that the normal assembly and use functions of the cavity 3 are not affected.
[0041] In this application, by setting the wear-resistant strip 2 only in a specific area, the thermal impact on the substrate 1 is effectively reduced through the strip-shaped wear-resistant strip 2, avoiding changes to the overall microstructure and properties of the substrate 1. Compared with large-area welding, the heat applied to the strip-shaped wear-resistant strip 2 is more concentrated and less, thereby significantly reducing the possibility of overall deformation of the substrate 1. This is particularly suitable for substrate 1 workpieces with complex shapes or high dimensional accuracy requirements. Furthermore, the strip-shaped treatment reduces residual stress generated during welding, lowering the risk of fatigue cracks in the component during use. The strip-shaped wear-resistant strip 2 can usually be processed quickly by automated equipment, effectively improving overall production efficiency while reducing errors caused by manual intervention. Moreover, because only the areas requiring reinforcement are treated, expensive alloy materials can be saved, reducing production and subsequent maintenance costs.
