Description

Technical Field

[0001] This utility model relates to the field of polishing rod technology, and in particular to a polishing rod that avoids tearing and damage during abrasion. Background Technology

[0002] With the widespread application of precision manufacturing and fine surface treatment processes, polishing rods, as important tools for surface finishing and improving the smoothness of industrial products, have been widely used in various fields such as hardware, plastics, wood, and ceramics. Especially when manually or mechanically assisted grinding workpieces with complex shapes or sharp edges, polishing rods have become an indispensable key component due to their flexibility and polishing efficiency.

[0003] In existing technologies, traditional polishing rods typically consist of a core rod structure covered with an outer abrasive layer. The inner layer generally uses foam, rubber, or EVA material as a cushioning support, while the outer layer is made of fiber cloth or flocked abrasive, used to achieve flexible contact with the workpiece and fine surface treatment. Its working principle involves applying force by hand or in conjunction with a rotating device, causing the outer abrasive layer of the polishing rod to generate uniform friction with the surface to be processed, thereby achieving the effect of grinding and polishing.

[0004] However, existing polishing rods often suffer from problems such as tearing, breakage, or peeling of the abrasive layer during use, especially in edge grinding or high-frequency use, due to weak interlayer adhesion, insufficient elastic support, or lack of tensile reinforcement. This not only reduces the polishing effect but also seriously affects the product's service life and work efficiency. Therefore, how to improve the structural strength and tear resistance of polishing rods has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polishing rod that avoids tearing and damage during abrasion, aiming to improve the problem that traditional polishing rods are prone to tearing and damage during polishing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polishing rod that avoids tearing and damage during abrasion, comprising a polishing rod body, a silicone ring fixedly connected to the outer wall of the polishing rod body, an abrasion ring fixedly connected to the outer wall of the silicone ring, a central support layer disposed inside the polishing rod body, a buffer elastic layer fixedly connected to the outer wall of the central support layer, a fiber reinforcement layer fixedly connected to the outer wall of the buffer elastic layer, and an adhesion stabilizing layer fixedly connected to the outer wall of the fiber reinforcement layer.

[0007] As a further description of the above technical solution:

[0008] The polishing rod body is composed of a central support layer, a buffer elastic layer, a fiber reinforcement layer, and an adhesion stabilizing layer.

[0009] As a further description of the above technical solution:

[0010] The central support layer is used to provide overall rigidity and deformation resistance.

[0011] As a further description of the above technical solution:

[0012] The buffer elastic layer is used to reduce the pulling force on the external abrasion ring.

[0013] As a further description of the above technical solution:

[0014] The length of the silicone ring is 12±0.1mm, and the length of the abrasion ring is 10±0.1mm.

[0015] As a further description of the above technical solution:

[0016] The diameter of the abrasion ring is 7.75±0.1mm.

[0017] As a further description of the above technical solution:

[0018] The diameter of the silicone ring is 6±0.1mm.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, the central support layer is the main load-bearing structure, the buffer elastic layer plays a role in unloading and buffering, the fiber reinforcement layer prevents the surface abrasive from cracking due to stretching, and the adhesion stabilizing layer is viscoelastic polyurethane, which is used to firmly bond the outer abrasive layer with the lower structure, thereby achieving the effect of preventing the abrasive from tearing and breaking.

[0026] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a polishing rod that prevents abrasion tearing and damage. The rod includes a polishing rod body 1, which serves as the overall support structure, fixing and bearing the functional layers and ensuring force transmission and stability during polishing. A silicone ring 2 is fixedly connected to the outer wall of the polishing rod body 1. The silicone ring 2 acts as a connecting buffer medium, possessing a certain degree of flexibility to effectively alleviate localized stress concentration caused by uneven force application during polishing, thereby preventing tearing at the interface between the abrasion ring 3 and the polishing rod body 1. An abrasion ring 3 is fixedly connected to the outer wall of the silicone ring 2, and the abrasion ring 3 is used for direct contact with the workpiece surface. The polishing rod, through contact and friction, achieves grinding and polishing. Its material must possess good wear resistance and adaptability to ensure stable performance under different surface treatment requirements. The polishing rod body 1 has a central support layer 4 inside. This central support layer 4 serves as the core load-bearing component, providing the necessary structural rigidity and bending resistance to maintain its shape stability during high-frequency reciprocating motion or edge operations, preventing deformation or breakage. A buffer elastic layer 5 is fixedly connected to the outer wall of the central support layer 4. The buffer elastic layer 5 provides flexible support, absorbing external impacts and periodic stress fluctuations, reducing stress on the external abrasive ring 3. The tensile force helps extend the service life of the abrasion ring 3 and reduce the risk of breakage. A fiber reinforcement layer 6 is fixedly connected to the outer wall of the buffer elastic layer 5. The fiber reinforcement layer 6 has good tensile and shear resistance, effectively preventing surface layer tearing or structural instability under stress on the polishing rod, enhancing the overall mechanical integrity of the rod. An adhesion stabilizing layer 7 is fixedly connected to the outer wall of the fiber reinforcement layer 6. As a transitional bonding structure, the adhesion stabilizing layer 7 uses high-adhesion materials such as viscoelastic polyurethane to ensure that the abrasion ring 3 remains tightly bonded to the underlying structure under repeated stress, preventing interface delamination or slippage. The body 1 is composed of a central support layer 4, a buffer elastic layer 5, a fiber reinforcement layer 6, and an adhesion stabilizing layer 7. The above structural layers work together to achieve an organic unity of structural strength, impact buffering, and surface tear resistance, thereby improving the overall durability and reliability of the polishing rod. The central support layer 4 is used to provide overall rigidity and deformation resistance, and the buffer elastic layer 5 is used to reduce the pulling force on the external abrasion ring 3. The length of the silicone ring 2 is 12±0.1mm, the length of the abrasion ring 3 is 10±0.1mm, the diameter of the abrasion ring 3 is 7.75±0.1mm, and the diameter of the silicone ring 2 is 6±0.1mm.

[0028] Working principle: When using this polishing rod that prevents abrasion tearing and damage, the polishing rod body 1 is composed of a central support layer 4, a buffer elastic layer 5, a fiber reinforcement layer 6, and an adhesion stabilizing layer 7. The central support layer 4 is made of stainless steel and serves as the main load-bearing structure of the polishing rod, providing overall rigidity and deformation resistance to prevent internal structural collapse due to local overload, which could induce tearing of the outer layer. The buffer elastic layer 5 is an elastic material that absorbs impact loads from the outside during polishing, reducing the pulling force on the outer abrasion layer and providing a buffering effect. The fiber reinforcement layer 6 is made of woven aramid fiber, which enhances tear resistance and limits the deformation of the elastic layer under high-frequency vibration and deformation, preventing the surface abrasion from cracking due to stretching. The adhesion stabilizing layer 7 is made of viscoelastic polyurethane, which is used to firmly bond the outer abrasion layer to the underlying structure, preventing edge tearing and damage caused by interlayer delamination or peeling. The silicone ring 2 is used to reduce buffering, and the abrasion ring 3 polishes the workpiece, achieving the effect of preventing abrasion tearing and damage.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
