Description

Technical Field

[0001] This utility model relates to the field of diamond wire saws, and in particular to a diamond wire saw with a diamond-assisted cutting structure. Background Technology

[0002] A diamond wire saw is a highly specialized cutting tool widely used in stone processing, concrete cutting, ceramics and glass processing, and other fields. A diamond wire saw is a flexible, strip-shaped tool composed of multiple strands of high-strength steel wire rope, with a series of diamond beads evenly strung along this rope at specific intervals. Its unique design and working principle combine the superhardness of diamond with the convenience of flexible rope, enabling it to perform efficient and precise cutting operations on various hard materials.

[0003] Chinese Patent Application No. 201320845340.5 discloses a diamond wire saw with a porous structure of beads. It consists of beads, steel wire rope, and bead fixing sleeve. The outer surface of the beads has multiple small holes, and low-hardness pore-forming particles are fixed inside the metal matrix of the beads.

[0004] Existing diamond wire saws have the following disadvantages:

[0005] It is difficult to guarantee that the cutting ability of several diamond beads on a diamond wire saw is completely consistent. Often, due to the rapid wear of a few beads, when the diamond beads wear down from the working layer to the base, the exposed wire rope wears and forms a weak point, which causes the risk of rope breakage and shortens the service life of the wire saw. The working layer of the other beads is not fully utilized, resulting in waste. Utility Model Content

[0006] Therefore, there is a need to provide a diamond wire saw with a diamond-assisted cutting structure to solve the problem of exposed steel wire rope wear and the risk of rope breakage when the diamond beads wear from the working layer to the base.

[0007] To achieve the above objectives, this embodiment provides a diamond wire saw with a diamond-assisted cutting structure, comprising:

[0008] Wire rope;

[0009] Multiple diamond beads, wherein the multiple diamond beads are spaced apart and looped onto the steel wire rope; and

[0010] Multiple diamond-assisted cutting structures are spaced apart on the steel wire rope, with one diamond-assisted cutting structure between two adjacent diamond beads. Each diamond-assisted cutting structure includes a support member and diamond abrasive grains arranged on the outer wall of the support member. In the radial direction of the steel wire rope, the diamond abrasive grains located on the outer wall of the support member are located outside the matrix of the diamond beads.

[0011] Furthermore, the support member is a spring; or:

[0012] The support member is ring-shaped.

[0013] Furthermore, the spring is a metal helical spring, the outer wall of the metal helical spring is coated with brazing material, and diamond abrasive grains are sprinkled on the surface of the brazing material. The diamond abrasive grains are fixed to the metal helical spring by brazing.

[0014] Furthermore, the diamond abrasive grains are 30 mesh to 60 mesh.

[0015] Furthermore, the metal helical spring is a square wire metal helical spring, and the cross-section of the wire in the square wire metal helical spring is rectangular.

[0016] Furthermore, the square wire metal helical spring has an inner diameter of 5.1mm to 5.8mm, an outer diameter of 7.1mm to 7.8mm, a rectangular cross-section with a length and width of 1mm to 1.3mm, a length of 14mm to 15mm, and 8 to 10 coils.

[0017] Furthermore, the outer diameter of the bead fixing sleeve is 8mm to 10mm;

[0018] The inner diameter of the matrix of the diamond beads is 5.1 mm and the outer diameter is 7 mm. The inner diameter of the working layer of the diamond beads is 7 mm and the outer diameter is 11.6 to 12.0 mm.

[0019] The diameter of the steel wire rope is 4.8mm to 4.9mm.

[0020] Furthermore, the brazing filler extends from one end of the metal helical spring to the other end, crossing the interval between two adjacent turns of the metal helical spring.

[0021] Furthermore, it also includes:

[0022] Multiple bead fixing sleeves, one of the bead fixing sleeves is fitted onto one of the diamond auxiliary cutting structures and supports two adjacent diamond beads.

[0023] Furthermore, the outer diameter of the bead fixing sleeve is 8mm to 10mm.

[0024] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0025] When a diamond wire saw is in operation, the working layer on the diamond beads first contacts the object being cut, generating a cutting action. With continued use, the wear of the diamond beads gradually increases. When the wear of the diamond beads reaches a certain level, specifically the diamond auxiliary cutting structure, the diamond abrasive grains on the auxiliary cutting structure also begin to participate in the cutting process. These additional diamond abrasive grains can continue to provide effective cutting force, thus compensating for the reduced cutting efficiency caused by bead wear. Furthermore, when too many beads on the wire saw are lost due to abnormal wear, the diamond abrasive grains on the auxiliary cutting structure can also provide some protection, preventing the wire rope from being directly exposed and damaged, thereby extending the overall service life of the wire saw.

[0045] Please see Figures 1 to 4 This embodiment provides a diamond wire saw with a diamond-assisted cutting structure 3, comprising:

[0046] Wire rope 1;

[0047] Multiple diamond beads 2 are spaced apart and looped onto the steel wire rope 1; and

[0048] Multiple diamond-assisted cutting structures 3 are spaced apart on the wire rope 1. There is one diamond-assisted cutting structure 3 between two adjacent diamond beads 2. The diamond-assisted cutting structure 3 includes a support member 31 and diamond abrasive grains 32 arranged on the outer wall of the support member 31. In the radial direction of the wire rope 1, the diamond abrasive grains 32 located on the outer wall of the support member 31 are located outside the base 21 of the diamond beads 2 to ensure that during use, the diamond abrasive grains 32 can contact the object to be cut before the base 21 and perform cutting.

[0049] It is worth mentioning that the diamond bead 2 includes a columnar substrate 21 and a working layer 22 disposed on the outer wall of the substrate 21. The working layer 22 includes a matrix 221 and diamond abrasive grains 222 mixed in the matrix 221, with the structure as follows: Figure 2 and Figure 3 As shown.

[0050] When a diamond wire saw is in operation, the working layer 22 on the diamond beads 2 first contacts the object being cut and generates a cutting action. With continued use, the wear of the diamond beads 2 gradually increases. When the wear of the diamond beads 2 reaches a certain level, i.e., when it wears down to the position of the diamond auxiliary cutting structure 3, the diamond abrasive grains 32 set on the diamond auxiliary cutting structure 3 also begin to participate in the cutting process. These additional diamond abrasive grains 32 can continue to provide effective cutting force, thereby compensating for the reduced cutting efficiency due to bead wear. Furthermore, when too many beads on the wire saw are lost due to abnormal wear, the diamond abrasive grains 32 on the diamond auxiliary cutting structure 3 can also provide some protection, preventing the wire rope 1 from being directly exposed and damaged, thus extending the overall service life of the wire saw.

[0051] Please see Figure 1 and Figure 4 In this embodiment, the support member 31 is a spring. The spring not only provides sufficient support strength to fix the diamond abrasive grains 32, but also, due to its elastic properties, can adapt to a certain degree of bending deformation during the cutting process.

[0052] In some embodiments, the support 31 is annular, allowing the diamond abrasive grains 32 to be evenly distributed.

[0053] Please see Figure 1 and Figure 4 In this embodiment, the spring is a metal helical spring. The outer wall of the metal helical spring is coated with brazing filler 33, and diamond abrasive grains 32 are sprinkled on the surface of the brazing filler 33. The diamond abrasive grains 32 are fixed to the metal helical spring by brazing. During the heating process, the brazing filler 33 melts and encapsulates the diamond abrasive grains 32, and a strong bond is formed after cooling.

[0054] In some embodiments, the diamond abrasive grains 32 are welded to the metal helical spring to form a fixed connection.

[0055] In this embodiment, the diamond abrasive grains 32 are 30-60 mesh. Optionally, the diamond abrasive grains 32 are 30-35 mesh. Larger diamond abrasive grains 32 provide stronger cutting force and are suitable for cutting materials with higher hardness or rougher surfaces. Optionally, the diamond abrasive grains 32 are 35-40 mesh. Although smaller diamond abrasive grains 32 have slightly less cutting force than the former, they have advantages in cutting accuracy and surface finish, and are suitable for applications requiring high-quality cut surfaces.

[0056] Thus, by selecting the appropriate abrasive grain size, optimal cutting efficiency and precision can be achieved for different cutting objects and requirements. For example, larger abrasive grains are suitable for quickly removing large amounts of material, while smaller abrasive grains are more suitable for fine machining.

[0057] Please see Figure 2 In this embodiment, the metal helical spring is a square wire metal helical spring, and the cross-section of the wire in the square wire metal helical spring is rectangular. Because the cross-section of the wire in the square wire metal helical spring is rectangular, it has a larger surface area than a spring with a circular cross-section, and has more surface area that can be used to fix the diamond abrasive grains 32.

[0058] Please see Figure 1 In this embodiment, the square wire metal helical spring has an inner diameter of 5.1mm to 5.8mm, an outer diameter of 7.1mm to 7.8mm, a rectangular cross-section with a length and width of 1mm to 1.3mm, a length of 14mm to 15mm, and 8 to 10 coils (preferably 9). The outer diameter of the bead fixing sleeve 4 is 8mm to 10mm. The inner diameter of the base 21 of the diamond bead 2 is 5.1mm, the outer diameter is 7mm, and the inner diameter of the working layer 22 of the diamond bead 2 is 7mm, the outer diameter is 11.6mm. The diameter of the wire rope 1 is 4.8mm to 4.9mm. During the cutting process, when the overall diameter of a bead is reduced to 8mm to 8.2mm, the diamond on the surface of the support member 31 on both sides of the bead begins to participate in the cutting work, which improves the cutting ability, avoids the wire rope 1 from being exposed, and extends the working time of the wire saw.

[0059] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the brazing filler 33 extends from one end of the metal helical spring to the other, crossing the gap 311 between adjacent turns of the metal helical spring. The brazing filler 33 almost covers the entire outer wall of the metal helical spring and crosses the gap 311 between adjacent turns, which can provide a larger contact area, thereby making the diamond abrasive grains 32 more firmly fixed to the spring surface and reducing the risk of abrasive grains falling off during use.

[0060] Please see Figure 1 In this embodiment, the diamond wire saw further includes:

[0061] Multiple bead fixing sleeves 4 are provided. One bead fixing sleeve 4 is fitted onto a diamond auxiliary cutting structure 3 and supports two adjacent diamond beads 2.

[0062] The use of the bead fixing sleeve 4 enhances the stability of the diamond beads 2 on the wire rope 1, reducing bead displacement caused by vibration or external forces during the cutting process. By maintaining a consistent distance between adjacent diamond beads 2, it ensures that each bead functions uniformly during the cutting process, avoiding uneven cutting caused by changes in distance, thereby improving cutting accuracy.

[0063] Please see Figure 1 In this embodiment, the outer diameter of the bead fixing sleeve 4 is 8mm to 10mm.

[0064] The manufacturing process of a diamond wire saw is as follows:

[0065] Preparation of diamond-assisted cutting structure 3: Nickel-based brazing filler 33 is applied to the outer surface of the metal helical spring, and 30 / 35 and 35 / 40 mesh diamonds are sprinkled on the surface of the filler. After fixing, it is placed in a vacuum brazing furnace and brazing is completed at 1020℃.

[0066] Assembly: The prepared diamond auxiliary cutting structure 3 and diamond beads 2 are alternately threaded onto the steel wire rope 1, and then placed into the injection mold for injection molding to form the bead fixing sleeve 4 with an outer diameter of 8-10mm.

[0067] Sharpening: Use a silicon carbide grinding wheel to sharpen the diamond bead 2 to complete the production of the diamond wire saw.

[0068] This application has the following beneficial effects:

[0069] 1. By setting up the diamond-assisted cutting structure 3, it not only supports the beads and prevents the beads from shifting and causing the steel wire rope 1 to be exposed and worn, but also participates in the cutting work after the working layer 22 of the beads is worn to a certain extent, thereby improving the overall cutting ability.

[0070] 2. It increases the service life of the wire saw and reduces the risk of rope breakage due to inconsistent wear of the beads.

[0071] 3. The diamond abrasive grains 32 of the beaded and diamond-assisted cutting structure 3 are fully utilized, reducing resource waste.

[0072] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
