Description
Technical Field
[0001] This invention belongs to the technical field of metal rubber materials and vibration damping devices, specifically relating to a layered composite metal rubber with adjustable mechanical properties and its preparation method. Background Technology
[0002] Metal rubber, as an all-metal elastic porous damping material, combines the strength and weather resistance of metal with the elasticity and damping properties of rubber. It has wide applications in vibration reduction, vibration isolation, and sealing in aerospace, precision instruments and other fields.
[0003] Currently, the preparation process of metal rubber is mainly divided into two technical routes: spiral winding method and metal wire mesh method (metal wire mesh rubber). Among them, the metal wire mesh method directly uses metal wire mesh (mesh belt) as raw material, and forms it through winding and stamping. The process flow is short and the production efficiency is high, so it has been widely used.
[0004] However, existing metal wire mesh rubber products are all manufactured using a single process parameter (i.e., the same type of wire mesh with fixed material, wire diameter, mesh count, and width). The mechanical properties of the material (such as stiffness and damping) are essentially fixed once the wire mesh parameters and molding density are determined, lacking the means to actively and flexibly control them during the manufacturing process. When engineering applications require different stiffness and damping for vibration damping components, it is often necessary to redesign the wire mesh parameters or molds, making it difficult to achieve "design on demand, multiple uses from one type."
[0005] Therefore, how to introduce new performance regulation dimensions on the basis of the metal wire mesh rubber technology route to achieve active and precise adjustment of mechanical properties is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0006] The purpose of this invention is to provide a layered composite metal rubber with adjustable mechanical properties and its preparation method. By layering and winding metal wire mesh with different process parameters and adjusting the length (weight) ratio, the mechanical properties can be actively adjusted, which effectively solves the technical defects of existing metal wire mesh rubber that use a single process parameter mesh belt and have difficult mechanical properties that are difficult to actively control.
[0007] Technical solution to achieve the purpose of this invention: In a first aspect, the present invention provides a layered composite metal rubber with adjustable mechanical properties. The metal rubber is formed by layering and pressing at least two metal wire meshes with different process parameters. It has a macroscopic layered composite structure with metal wire mesh layers of different process parameters distributed along the thickness direction. The mechanical properties of the metal rubber are actively controlled by adjusting the winding length ratio of the metal wire meshes with different process parameters.
[0008] Furthermore, the metal wire meshes with different process parameters are distinguished by at least one of the following dimensions: material, wire diameter, mesh count, and wire mesh width.
[0009] Furthermore, the mechanical properties include stiffness, which can be continuously or steppedly adjusted within a predetermined range by adjusting the length ratio.
[0010] Secondly, the present invention provides a method for preparing a layered composite metal rubber with adjustable mechanical properties, comprising: winding a first metal wire mesh around a mandrel to form a first wire mesh layer, and then winding a second metal wire mesh around the outside of the first wire mesh layer to form a second wire mesh layer; forming a composite blank with a layered structure; and cold-pressing the composite blank to obtain an integrated layered composite metal rubber; wherein the first metal wire mesh and the second metal wire mesh are metal wire meshes with different process parameters, and their length ratio is adjusted by controlling the winding length of the first metal wire mesh and the second metal wire mesh.
[0011] Furthermore, the first and second metal wire meshes differ in at least one dimension: material, wire diameter, mesh count, and width.
[0012] Furthermore, the length ratio of the first metal wire mesh to the second metal wire mesh is predetermined based on the target mechanical properties.
[0013] Furthermore, the cold pressing is performed at room temperature, and the specific pressure and holding time are determined by those skilled in the art through conventional experimental methods based on the dimensions and density requirements of the target product. The beneficial technical effects of this invention are as follows: (1) It opens up a new dimension for the performance control of metal wire mesh rubber. Existing metal wire mesh rubber all use mesh belts with single process parameters, and mechanical properties can only be achieved by adjusting density or macroscopic dimensions of the sample. This invention introduces "mesh with multiple process parameters" into the field of metal wire mesh rubber for the first time. By simply adjusting the winding length ratio of different meshes, the stiffness, damping and other mechanical properties of the product can be actively and accurately controlled within a large range, realizing "one type, multiple uses, and design on demand".
[0014] (2) The control method is simple and the cost is extremely low. There is no need to change the mold, replace the equipment, or add new process steps. Only by adding a "belt changing" operation and controlling the winding length in the winding stage, the performance can be greatly adjusted. This technical solution is very easy to promote and implement on existing production lines.
[0015] (3) The product structure is unique. The product of this invention has a clear macroscopic layered composite structure, which is fundamentally different from the traditional single-parameter metal wire mesh rubber (uniform winding structure). This unique layered structure itself brings a new mechanical response mechanism to the material.
[0016] (4) Strong applicability. The core concept of this invention is to layer and composite wire meshes with different process parameters and adjust the length ratio. It is applicable to parameter differences in multiple dimensions such as material, wire diameter, mesh count, and width. The combination of wire meshes can be flexibly selected according to engineering needs, and it has a wide range of industrial application value. Attached Figure Description

[0018] In the diagram, 1 is the mandrel, 2 is the first metal wire mesh, and 3 is the second metal wire mesh. Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0020] The core concept of this invention lies in combining two or more metal wire meshes with different process parameters (different materials, wire diameters, mesh counts, widths, etc.) through layered winding, and precisely controlling the winding length (i.e., weight) ratio of each wire mesh, thereby achieving active control over the mechanical properties of the final product. Specifically: This invention provides a layered composite metal rubber with adjustable mechanical properties, which is formed by layering and pressing at least two metal wire meshes with different process parameters. It has a macroscopic layered composite structure with metal wire mesh layers with different process parameters distributed along the thickness direction. The mechanical properties of the metal rubber can be actively controlled by adjusting the winding length ratio (i.e., weight ratio) of the metal wire meshes with different process parameters.
[0021] The differences between metal wire meshes with different process parameters are selected from at least one of the following dimensions: material, wire diameter, mesh count, and wire width.
[0022] Mechanical properties include stiffness, which can be continuously or steppedly adjusted within a predetermined range by adjusting the length ratio (weight ratio).
[0023] This invention also provides a method for preparing a layered composite metal rubber with adjustable mechanical properties, specifically including the following steps: Step S1: Layered winding. Fix one end of the first wire mesh to the mandrel, rotate the mandrel to wind it to a predetermined number of layers or thickness to form the first wire mesh layer; then fix the end of the second wire mesh to the outside of the first wire mesh layer, continue to rotate the mandrel to wind it to a predetermined number of layers or thickness to form the second wire mesh layer; in this way, various wire meshes with different process parameters can be wound sequentially to obtain a composite blank with a layered structure; Step S2: Proportional Control. During the winding process, the length ratio between different wire meshes is precisely set by controlling the winding length (or number of turns, layers) of each wire mesh. Since the linear density (weight per unit length) of each wire mesh is a known constant, this length ratio directly corresponds to the weight ratio. Step S3: Cold pressing. The composite blank is removed from the mandrel and placed in a mold for cold pressing at room temperature, so that the mesh layers are tightly interlocked to form an integrated layered composite metal mesh rubber. The specific pressure and holding time of cold pressing are related to the external dimensions, density requirements of the target product, as well as the mesh material and specifications. Those skilled in the art can determine appropriate molding parameters according to actual needs, combined with conventional process knowledge and conventional experiments in the field.
[0024] The first and second wire meshes differ in at least one of the following dimensions: material, wire diameter, mesh count, and width.
[0025] Example 1: Composite of wire mesh with different materials (304 stainless steel mesh belt and beryllium bronze mesh belt, length ratio 1:1) Step S1: Raw material preparation First metal wire mesh: The material is 304 austenitic stainless steel, the wire diameter is 0.15 mm, the weave count is 100 mesh (i.e., 100 mesh openings per inch), and the wire mesh width is 50 mm.
[0026] Second metal wire mesh: material is C17200 beryllium bronze, wire diameter is 0.15 mm, weave count is 100 mesh, and wire mesh width is 50 mm.
[0027] Cut the two types of wire mesh to the required lengths according to the preset length ratio and set them aside.
[0028] Step S2: Layered winding like Figure 1 As shown, a first metal wire mesh (304 stainless steel) of length L1 is wound around a mandrel. After the first metal wire mesh is wound, a second metal wire mesh (beryllium bronze) of length L2 is wound around the outside of the first metal wire mesh (as shown). Figure 2 As shown). At this point, the length ratio of the two wire meshes is L1:L2 = 1:1, completing the preparation of the metal wire mesh rubber composite blank (as shown). Figure 3 (As shown).
[0029] Step S3: Cold pressing The composite blank obtained by layered winding is removed from the mandrel and placed in a mold. It is then cold-pressed at room temperature to tightly integrate the two layers of wire mesh, resulting in an integrated layered composite metal-rubber, such as... Figure 4 As shown. The specific molding pressure and holding time are determined based on the size and density requirements of the sample, and conventional cold pressing process conditions in this field can be used.
[0030] Step S4: Product performance: Tested, the stiffness and damping performance of this sample are between those of pure stainless steel wire mesh rubber and pure beryllium bronze wire mesh rubber.
[0031] Example 2: Composite of wire mesh with different materials (304 stainless steel mesh belt and beryllium bronze mesh belt, length ratio 2:1) Step S1: Raw material preparation Same as Example 1.
[0032] Step S2: Layered winding like Figure 1 As shown, a first metal wire mesh (304 stainless steel) of length L1 is wound around a mandrel. A second metal wire mesh (beryllium bronze) of length L2 is wound around the outside of the first metal wire mesh (as shown). Figure 2 (As shown). At this time, the length ratio of the two types of wire mesh is L1:L2 = 2:1.
[0033] Step S3: Cold pressing: Same as in Example 1.
[0034] Step S4: Product performance: Tests showed that the stiffness of this sample was higher than that of the sample in Example 1, while the damping was lower than that of the sample in Example 1.
[0035] Example 3: Composite of wire mesh with different materials (304 stainless steel mesh belt and beryllium bronze mesh belt, length ratio 1:2) Step S1: Raw material preparation Same as Example 1.
[0036] Step S2: Layered winding like Figure 1 As shown, a first metal wire mesh (304 stainless steel) of length L1 is wound around a mandrel. A second metal wire mesh (beryllium bronze) of length L2 is wound around the outside of the first metal wire mesh (as shown). Figure 2 (As shown). At this time, the length ratio of the two types of wire mesh is L1:L2 = 1:2.
[0037] Step S3: Cold pressing: Same as in Example 1.
[0038] Step S4: Product performance: Tests showed that the stiffness of this sample was lower than that of the sample in Example 1, while the damping was higher than that of the sample in Example 1.
[0039] Comparative analysis of Examples 1-3 Examples 1-3 above demonstrate that, while keeping other process conditions constant, the stiffness and damping performance of the final product can be actively controlled simply by changing the winding length ratio of the two types of wire mesh. As the proportion of stainless steel mesh (a material with higher stiffness) increases, the product stiffness increases and the damping decreases; conversely, as the proportion of beryllium bronze mesh (a material with higher damping) increases, the product stiffness decreases and the damping increases. By adjusting the length ratio, continuous adjustment can be achieved within the performance range of both pure stainless steel and pure beryllium bronze products.
[0040] Example 4: Composite wire mesh of the same material but different wire diameters (304 stainless steel, fine wire to coarse wire, length ratio 1:1) Step S1: Raw material preparation First metal wire mesh: The material is 304 austenitic stainless steel, the wire diameter is 0.15 mm, the weave count is 100 mesh, and the wire mesh width is 50 mm.
[0041] The second type of wire mesh is made of 304 austenitic stainless steel, with a wire diameter of 0.3 mm, a weave count of 60 meshes, and a mesh width of 50 mm. Cut the two types of wire mesh to the required lengths according to the preset length ratio.
[0042] Step S2: Layered winding like Figure 1 As shown, a first metal wire mesh of length L1 (0.15 mm diameter) is wound around a mandrel. After the first metal wire mesh is wound, a second metal wire mesh of length L2 (0.3 mm diameter) is wound around the outside of the first metal wire mesh (as shown). Figure 2 (As shown). At this point, the length ratio of the two wire meshes is L1:L2 = 1:1, completing the preparation of the metal wire mesh rubber composite blank.
[0043] Step S3: Cold pressing: Same as in Example 1.
[0044] Step S4: Product performance: Tests showed that the stiffness and damping performance of this sample were between those of pure fine wire mesh rubber and pure coarse wire mesh rubber.
[0045] Example 5: Composite wire mesh of the same material but different wire diameters (304 stainless steel, fine wire to coarse wire, length ratio 2:1) Step S1: Raw material preparation Same as Example 4.
[0046] Step S2: Layered winding like Figure 1As shown, a first metal wire mesh of length L1 (0.15 mm diameter) is wound around a mandrel. After the first metal wire mesh is wound, a second metal wire mesh of length L2 (0.3 mm diameter) is wound around the outside of the first metal wire mesh (as shown). Figure 2 (As shown). At this time, the length ratio of the two types of wire mesh is L1:L2 = 2:1.
[0047] Step S3: Cold pressing: Same as in Example 1.
[0048] Step S4: Product performance: Tests showed that the stiffness of this sample was lower than that of the sample in Example 4, while the damping was higher.
[0049] Example 6: Composite wire mesh of the same material but different wire diameters (304 stainless steel, fine wire to coarse wire, length ratio 1:2) Step S1: Raw material preparation Same as Example 4.
[0050] Step S2: Layered winding like Figure 1 As shown, a first metal wire mesh of length L1 (0.15 mm diameter) is wound around a mandrel. After the first metal wire mesh is wound, a second metal wire mesh of length L2 (0.3 mm diameter) is wound around the outside of the first metal wire mesh (as shown). Figure 2 (As shown). At this time, the length ratio of the two types of wire mesh is L1:L2 = 1:2.
[0051] Step S3: Cold pressing Same as Example 1.
[0052] Step S4: Product Performance Tests showed that the stiffness of this sample was higher than that of the sample in Example 4, while the damping was lower.
[0053] Comparative analysis of Examples 4-6 Examples 4-6 above show that a higher proportion of coarse wire mesh (larger wire diameter) results in higher product stiffness; a higher proportion of fine wire mesh results in better product damping performance. By adjusting the winding length ratio of different wire diameter meshes, continuous control of stiffness and damping performance can be achieved.
[0054] The above examples demonstrate that regardless of differences in material, wire diameter, or other dimensions between the two types of wire mesh, the mechanical properties of the metal wire mesh rubber can be actively controlled by employing the "layered winding + controlled length ratio" preparation method. The basic principle of control is that changing the winding length ratio (i.e., weight ratio) of different wire meshes continuously alters the stiffness, damping, and other mechanical properties of the final product, and the trend of change is clearly correlated with the mechanical characteristics of each wire mesh itself (such as the elastic modulus of the material and the single-filament stiffness determined by the wire diameter).
[0055] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. All contents not described in detail in the present invention can be derived from existing technologies.
