Description

Technical Field

[0001] The present invention relates to the technical field of composite material preparation, and more specifically, to a tin-based Babbitt alloy composite material and a preparation method thereof. Background Art

[0002] Tin-based Babbitt alloys are well-known for their low friction coefficient, excellent wear resistance and embeddability. They are widely used in the field of low-speed heavy-duty sliding bearings, with the properties of reducing friction resistance and wear, and to a certain extent accommodating foreign impurities or hard particles, thus maintaining the good operating state of the bearings. However, with the continuous improvement of the performance requirements of mechanical equipment in modern industry, the limitations of traditional tin-based Babbitt alloys under high-speed and high-load conditions have gradually emerged. Specifically, under high-speed conditions, the heat generated by friction accumulates rapidly, resulting in a sharp increase in the alloy temperature. This not only reduces its mechanical properties, but may also cause the alloy to soften, deform or even fail.

[0003] In order to overcome the performance bottleneck of traditional tin-based Babbitt alloys under high-speed and high-load conditions, in recent years, researchers have mixed reinforcing fibers with excellent mechanical properties, thermal stability, thermal conductivity and self-lubricating properties with tin-based Babbitt alloys to prepare composite materials.

[0004] However, there are at least one of the following problems in the related technologies: the preparation of tin-based Babbitt alloy composite materials in the prior art. Due to the large density difference between the reinforcing fibers and the tin-based Babbitt alloy, problems such as delamination between the reinforcing fibers and the tin-based Babbitt alloy exist in ordinary casting processes and cold metal transfer additive manufacturing processes, and it is difficult to achieve uniform distribution of the reinforcing fibers in the tin-based Babbitt alloy. Summary of the Invention

[0005] The technical problem solved by the present invention is the preparation of tin-based Babbitt alloy composite materials in the prior art. Due to the large density difference between the reinforcing fibers and the tin-based Babbitt alloy, problems such as delamination between the reinforcing fibers and the tin-based Babbitt alloy exist in ordinary casting processes and cold metal transfer additive manufacturing processes, and it is difficult to achieve uniform distribution of the reinforcing fibers in the tin-based Babbitt alloy.

[0006] To solve the above technical problems, the present invention provides a preparation method of a tin-based Babbitt alloy composite material, and the preparation method includes:

[0007] Weaving long fiber filaments on the surface of tin-based Babbitt alloy filaments to obtain tin-based Babbitt alloy fiber materials;

[0008] Performing shaping treatment on the tin-based Babbitt alloy fiber materials;

[0009] Performing hot extrusion treatment on the tin-based Babbitt alloy fiber materials after the shaping treatment to obtain composite pipes;

[0010] Cut the composite pipe along the rotation axis to obtain the first composite plate;

[0011] Perform hot rolling on the first composite plate to obtain the second composite plate;

[0012] Roll multiple second composite plates to obtain the tin-based Babbitt alloy composite material.

[0013] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By sequentially performing sizing treatment, hot extrusion treatment, hot rolling treatment, and rolling treatment on the tin-based Babbitt alloy fiber material, the tin-based Babbitt alloy composite material is obtained, realizing the uniform dispersion of long fiber filaments in the tin-based Babbitt alloy filaments. And the bonding force between the long fiber filaments and the tin-based Babbitt alloy filaments during the rolling process is improved. At the same time, long fiber filaments are woven on the surface of the tin-based Babbitt alloy filaments. Since the friction coefficient of the long fiber filaments is small, it is beneficial to reduce the cold start friction force of the sliding bearing made of the tin-based Babbitt alloy composite material and reduce the friction coefficient of the tin-based Babbitt alloy composite material.

[0014] In an example of the present invention, the preparation method further includes: winding the tin-based Babbitt alloy fiber material around the outer wall of the sizing die in a spiral winding manner so that the shape of the tin-based Babbitt alloy fiber material is spring-shaped; wherein, the shape of the sizing die is cylindrical.

[0015] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By winding the tin-based Babbitt alloy fiber material around the outer wall of the cylindrical sizing die in a spiral winding manner to form a spring-shaped structure, the stress is effectively dispersed and the local stress concentration is reduced, thereby improving the fatigue resistance and fracture resistance of the tin-based Babbitt alloy composite material.

[0016] In an example of the present invention, the hot extrusion treatment includes: putting the sized tin-based Babbitt alloy fiber material into an extrusion die for hot extrusion treatment.

[0017] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By putting the sized tin-based Babbitt alloy fiber material into an extrusion die for hot extrusion treatment, the plastic deformation ability of the tin-based Babbitt alloy composite material is improved, enabling the tin-based Babbitt alloy fiber materials to be fully combined and retaining the regularly arranged fiber distribution structure.

[0018] In an example of the present invention, the extrusion temperature of the hot extrusion treatment is 180°C to 210°C.

[0019] Compared with the prior art, the technical effects achieved by adopting this technical solution: By controlling the extrusion temperature range of the hot extrusion treatment to be 180°C to 210°C, hot extruding the tin-based Babbitt alloy fiber material at 180°C to 210°C is beneficial to reducing the critical deformation pressure of the tin-based Babbitt alloy composite material, and realizing the preparation of the tin-based Babbitt alloy composite material at low pressure.

[0020] In an example of the present invention, the extrusion speed of the hot extrusion treatment is 2 mm / min to 4 mm / min.

[0021] Compared with the prior art, the technical effects achieved by adopting this technical solution: By controlling the extrusion speed of the hot extrusion treatment to be 2 mm / min to 4 mm / min, it is possible to avoid excessive deformation of the tin-based Babbitt alloy fiber material during the hot extrusion process, prevent the generation of internal cracks in the tin-based Babbitt alloy fiber material, thereby ensuring the exhaust effect of the tin-based Babbitt alloy fiber material during the hot extrusion process and ensuring the density of the tin-based Babbitt alloy fiber material.

[0022] In an example of the present invention, the number of rolling passes of the hot rolling treatment is 3 to 6 times; and / or the single rolling reduction of the hot rolling treatment is 5% to 7%.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution: By performing multi-pass rolling on the first composite plate, micro-cracks and surface pores inside the first composite plate can be gradually eliminated, the density of the first composite plate can be improved, thereby enhancing the mechanical properties and wear resistance of the first composite plate; controlling the number of rolling passes of the hot rolling treatment to be 3 to 6 times, so that the internal structure of the first composite plate is more uniform and the surface has no defects, avoiding the phenomena of local stress concentration and uneven performance.

[0024] Furthermore, by controlling the single rolling reduction of the hot rolling treatment to be 5% to 7%, the stress distribution inside the first composite plate can be better controlled, residual stress can be reduced, and the dimensional stability and anti-deformation ability of the first composite plate are improved.

[0025] In an example of the present invention, the single rolling quantity of the rolling treatment is defined as n, where n satisfies the relational expression: 2 ≤ n ≤ 4; where, n is an integer.

[0026] Compared with the prior art, the technical effects achieved by adopting this technical solution: By controlling the single rolling quantity of the rolling treatment to be 2 to 4, it is possible to avoid excessive single rolling reduction due to too many layers, reduce the rolling pressure on the intermediate second composite plate, so that multiple second composite plates can be fully combined and are not easily delaminated.

[0027] In one example of the present invention, the rolling rate of the rolling process is 5 mm / min to 10 mm / min; and / or the rolling temperature of the rolling process is 180°C to 210°C.

[0028] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By controlling the rolling rate of the rolling process to be 5 mm / min to 10 mm / min, this solution ensures uniform plastic deformation of multiple second composite plates during rolling, avoiding internal stress concentration caused by excessive deformation, thereby improving the strength and toughness of the tin-based babbit alloy composite material.

[0029] Furthermore, by controlling the rolling temperature of the rolling process to be 180°C to 210°C, this solution is beneficial to reducing the rolling pressure, enhancing the plastic deformation ability of the tin-based babbit alloy composite material, reducing defects such as pores and microcracks inside the tin-based babbit alloy composite material, and further improving the density of the tin-based babbit alloy composite material.

[0030] In one example of the present invention, the long fiber filaments include one or more of carbon fiber filaments and glass fiber filaments.

[0031] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: On the one hand, due to the extremely low thermal expansion coefficient of carbon fiber, adding carbon fiber filaments to the tin-based babbit alloy composite material can reduce the friction coefficient, thermal expansion coefficient, enhance the wear resistance, and improve the heat conduction ability of the tin-based babbit alloy composite material, thereby improving the dimensional stability of the tin-based babbit alloy composite material in a high-temperature environment. On the other hand, glass fiber filaments have good low friction coefficient and chemical stability. Adding glass fiber filaments to the tin-based babbit alloy composite material can reduce the friction coefficient of the tin-based babbit alloy composite material and improve the corrosion resistance.

[0032] On the other hand, the present invention also provides a tin-based babbit alloy composite material, which is made by using the preparation method in any of the above technical solutions. The tin-based babbit alloy composite material includes: 1 to 6 parts by mass of long fiber filaments, and the balance is tin-based babbit alloy filaments.

Moreover, the bonding force between the long fiber filaments and the tin-based Babbitt alloy filaments during the rolling process is improved. At the same time, long fiber filaments are woven on the surface of the tin-based Babbitt alloy filaments. Since the friction coefficient of the long fiber filaments is small, it is beneficial to reduce the cold start friction force of the sliding bearing made of the tin-based Babbitt alloy composite material, and reduce the friction coefficient of the tin-based Babbitt alloy composite material;

[0036] (2) By controlling the extrusion temperature range of the hot extrusion treatment to be 180°C to 210°C, performing hot extrusion treatment on the tin-based Babbitt alloy fiber material at 180°C to 210°C is beneficial to reducing the critical deformation pressure of the tin-based Babbitt alloy composite material, realizing the preparation of the tin-based Babbitt alloy composite material at low pressure, thereby improving the plastic deformation ability of the tin-based Babbitt alloy composite material, enabling the tin-based Babbitt alloy fiber materials to be fully combined, and retaining the regularly arranged fiber distribution structure;

[0047] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0048] As Figure 1 shown, the present invention provides a preparation method of a tin-based Babbitt alloy composite material, and the preparation method includes:

[0049] S100: Weave long fiber filaments on the surface of the tin-based Babbitt alloy wire 100 to obtain the tin-based Babbitt alloy fiber material 200;

[0051] S300: Perform hot extrusion treatment on the shaped tin-based Babbitt alloy fiber material 200 to obtain a composite pipe;

[0052] S400: Cut the composite pipe along the rotation axis to obtain the first composite plate 300;

[0053] S500: Perform hot rolling treatment on the first composite plate 300 to obtain a second composite plate;

[0054] S600: Roll a plurality of second composite plates to obtain a tin-based Babbitt alloy composite material.

[0055] Specifically, in this solution, a tin-based Babbitt alloy composite material is obtained by successively performing sizing treatment, hot extrusion treatment, hot rolling treatment, and rolling treatment on the tin-based Babbitt alloy fiber material 200, realizing the uniform dispersion of long fiber filaments in the tin-based Babbitt alloy wire 100, and obtaining the tin-based Babbitt alloy composite material. Moreover, the bonding force between the long fiber filaments and the tin-based Babbitt alloy wire 100 during the rolling process is improved. At the same time, long fiber filaments are woven on the surface of the tin-based Babbitt alloy wire 100. Since the friction coefficient of the long fiber filaments is small, it is beneficial to reduce the cold start friction resistance of the sliding bearing made of the tin-based Babbitt alloy composite material and reduce the friction coefficient of the tin-based Babbitt alloy composite material.

[0056] Furthermore, the preparation method further includes: winding the tin-based Babbitt alloy fiber material 200 around the outer wall of the sizing die 400 in a spiral winding manner so that the shape of the tin-based Babbitt alloy fiber material 200 is spring-shaped; wherein, the sizing die 400 is cylindrical.

[0057] Specifically, in this solution, by winding the tin-based Babbitt alloy fiber material 200 around the outer wall of the cylindrical sizing die 400 in a spiral winding manner to form a spring-shaped structure, the stress is effectively dispersed, and local stress concentration is reduced, thereby improving the fatigue resistance and fracture resistance of the tin-based Babbitt alloy composite material.

[0058] Furthermore, the hot extrusion treatment includes: putting the sized tin-based Babbitt alloy fiber material 200 into the extrusion die 500 for hot extrusion treatment.

[0059] Specifically, in this solution, by putting the sized tin-based Babbitt alloy fiber material 200 into the extrusion die 500 for hot extrusion treatment, the plastic deformation ability of the tin-based Babbitt alloy composite material is improved, enabling the tin-based Babbitt alloy fiber materials 200 to be fully combined and retaining a regularly arranged fiber distribution structure.

[0060] As Figure 5 shown, the extrusion die 500 includes an extrusion cylinder 510, an extrusion mandrel 520, an extrusion rod 540, and a heater 550. A receiving space 530 for accommodating the tin-based Babbitt alloy fiber material 200 is provided between the extrusion mandrel 520 and the extrusion cylinder 510. An extrusion rod 540 for extruding the tin-based Babbitt alloy fiber material 200 is provided at the top of the receiving space 530. The heater 550 is disposed around the outside of the extrusion cylinder 510 to heat the extrusion cylinder 510 during the hot extrusion treatment process. Further, the extrusion rod 540 is annular.

[0061] Furthermore, the extrusion temperature of the hot extrusion treatment is 180°C to 210°C.

[0062] Specifically, in this solution, the extrusion temperature range of the hot extrusion treatment is controlled to be 180°C to 210°C. Performing hot extrusion treatment on the tin-based Babbitt alloy fiber material 200 at 180°C to 210°C is beneficial to reducing the critical deformation pressure of the tin-based Babbitt alloy composite material, and realizing the preparation of the tin-based Babbitt alloy composite material at low pressure.

[0063] Furthermore, the extrusion speed of the hot extrusion treatment is 2 mm / min to 4 mm / min.

[0064] Specifically, in this solution, the extrusion speed of the hot extrusion treatment is controlled to be 2 mm / min to 4 mm / min to avoid excessive deformation of the tin-based Babbitt alloy fiber material 200 during the hot extrusion process, prevent the generation of internal cracks in the tin-based Babbitt alloy fiber material 200, thereby ensuring the exhaust effect of the tin-based Babbitt alloy fiber material 200 during the hot extrusion process and ensuring the density of the tin-based Babbitt alloy fiber material 200.

[0065] Further, the number of rolling passes of the hot rolling treatment is 3 to 6 times; and / or the single rolling reduction of the hot rolling treatment is 5% to 7%.

[0066] Specifically, in this solution, the first composite plate 300 is rolled in multiple passes to gradually eliminate the microcracks and surface pores inside the first composite plate 300, improve the density of the first composite plate 300, thereby enhancing the mechanical properties and wear resistance of the first composite plate 300; controlling the number of rolling passes of the hot rolling treatment to be 3 to 6 times, so that the internal structure of the first composite plate 300 is more uniform and the surface has no defects, avoiding the phenomena of local stress concentration and uneven performance.

[0067] More specifically, controlling the single rolling reduction of the hot rolling treatment to be 5% to 7% can better control the stress distribution inside the first composite plate 300, reduce the residual stress, and improve the dimensional stability and deformation resistance of the first composite plate 300.

[0068] Further, the single rolling quantity of the rolling treatment is defined as n, where n satisfies the relationship: 2 ≤ n ≤ 4; where, n is an integer.

[0069] Specifically, in this solution, the single rolling quantity of the rolling treatment is controlled to be 2 to 4 to avoid excessive single rolling reduction caused by too many layers, reducing the rolling pressure on the intermediate second composite plate, so that multiple second composite plates can be fully combined and are not easily delaminated.

[0070] Further, the rolling rate of the rolling treatment is 5 mm / min to 10 mm / min; and / or the rolling temperature of the rolling treatment is 180°C to 210°C.

[0071] Specifically, in this solution, the rolling rate of the controlled rolling process is 5 mm / min to 10 mm / min to ensure uniform plastic deformation of multiple second composite plates during rolling, avoid internal stress concentration caused by excessive deformation, and thus improve the strength and toughness of the tin-based Babbitt alloy composite material.

[0072] More specifically, in this solution, the rolling temperature of the controlled rolling process is 180°C to 210°C, which is beneficial to reducing the rolling pressure, enhancing the plastic deformation ability of the tin-based Babbitt alloy composite material, reducing defects such as pores and microcracks inside the tin-based Babbitt alloy composite material, and thus further improving the density and uniformity of the tin-based Babbitt alloy composite material.

[0073] Furthermore, the long fiber filaments include one or more of carbon fiber filaments and glass fiber filaments.

[0074] Specifically, on the one hand, due to the extremely low thermal expansion coefficient of carbon fiber, adding carbon fiber filaments to the tin-based Babbitt alloy composite material can reduce the friction coefficient, thermal expansion coefficient of the tin-based Babbitt alloy composite material, enhance the wear resistance, and improve the heat conduction ability, thereby improving the dimensional stability of the tin-based Babbitt alloy composite material in a high-temperature environment. On the other hand, glass fiber filaments have good low friction coefficient and chemical stability. Adding glass fiber filaments to the tin-based Babbitt alloy composite material can reduce the friction coefficient of the tin-based Babbitt alloy composite material and improve the corrosion resistance.

[0075] On the other hand, the present invention also provides a tin-based Babbitt alloy composite material, which is made by using the preparation method in any of the above technical solutions. The tin-based Babbitt alloy composite material includes: 1 to 6 parts by mass of long fiber filaments, and the balance is 100 parts by mass of tin-based Babbitt alloy filaments.
