Description

Technical Field

[0001] This utility model relates to the field of hot cutting blade technology, specifically to a green ceramic hot cutting blade and a hot cutting machine. Background Technology

[0002] The production process of ceramic substrates includes casting, cutting, punching, filling and printing, stacking, static pressing, cutting and sintering, etc. Among them, the cutting of ceramic substrates usually uses a hot cutting blade to cut the raw ceramic into blocks.

[0003] Publication No. CN217666824U describes an easy-to-install hot-cutting blade. When materials need to be cut, the heating coil is first activated by an external controller. The heating coil heats the heat pipe, which then transfers heat to the blade body, thereby heating the blade body. Once the temperature reaches a certain value, the material can be cut.

[0004] However, in the existing technology, if the blade is too thin, it will not be strong enough, which will result in uneven and wavy cut edges. To reduce the defect of wavy cut edges, the blade is usually made thicker. However, when cutting green ceramic with cavities, an excessively thick blade will easily squeeze the cavity structure, causing severe deformation of the cavity structure and reducing product quality. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a hot cutting blade and hot cutting machine for green ceramics. This solves the problem that in the prior art, if the blade is too thin, it will easily cause uneven cutting edges and wavy shapes. In order to alleviate the defect of wavy cutting edges, the blade is usually made thicker. However, when cutting green ceramics with cavities, the blade that is too thick will easily squeeze the cavity structure, resulting in serious deformation of the cavity structure and reducing the quality of the product.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a green ceramic hot cutting blade, including a clamping section and a cutting section connected together. The clamping section is used to fix the blade holder, and its thickness is greater than that of the cutting section. It also has a rounded corner transition with the cutting section on at least one side in its thickness direction. The cutting section is used to cut materials.

[0008] The clamping section and the cutting section are flush on one side in their thickness direction and transition with a rounded corner on the other side.

[0009] The cutting section includes a plurality of sharpening segments connected sequentially in a direction away from the clamping section, and the sharpening angle of the plurality of sharpening segments increases sequentially in a direction away from the clamping section.

[0010] In some embodiments, there are two cutting segments, and the clamping segment is connected to the two cutting segments in sequence, and at least on one side in the thickness direction, it has a rounded transition with the adjacent cutting segment.

[0011] The cutting angle of the cutting segment adjacent to the clamping section is α1, satisfying 1°≤α1≤2°, and the cutting angle of the cutting segment away from the clamping section is α2, satisfying 18°≤α2≤22°.

[0012] In some embodiments, the end of the cutting section away from the clamping section is tapered.

[0013] In some embodiments, the thickness of the clamping section is B1, satisfying 0.4 mm ≤ B1 ≤ 0.5 mm.

[0014] In some embodiments, the thickness of the cut segment is B2, satisfying 0.1 mm ≤ B2 ≤ 0.2 mm.

[0015] In some embodiments, the clamping section and the cutting section are integrally formed.

[0016] In some embodiments, the green ceramic hot cutting blade further includes a positioning flange disposed on the clamping section for insertion into a positioning hole located on the blade holder.

[0017] Secondly, this utility model also provides a hot cutting machine, which includes the green ceramic hot cutting blade as described in any of the above claims.

[0018] Compared with existing technologies, when using the green ceramic hot-cutting blade provided by this utility model, a relatively thicker clamping section is fixed on the blade holder, and the material is cut through a relatively thinner cutting section. Therefore, when the cutting section is set thinner, the rounded transition between the thinner cutting section and the thicker clamping section improves the connection strength between them and reduces the stress shear area. This ensures that the thinner cutting section still has sufficient strength to cut green ceramic, mitigating the defect of wavy, uneven edges when cutting green ceramic and making the cutting section less prone to breakage from the clamping section, thus guaranteeing blade quality. Furthermore, the thinner cutting section is less likely to compress the cavity structure when cutting green ceramic, preventing severe deformation of the green ceramic cavity structure and improving product quality.

[0019] Meanwhile, only one side of the clamping section and the cutting section is set with a rounded corner transition, and the other sides of the clamping section and the cutting section are set flush. This ensures the connection strength between the clamping section and the cutting section, while also effectively eliminating the shear stress area caused by the thickness difference between the clamping section and the cutting section. This ensures the connection strength between the two, makes them less prone to breakage, facilitates molding, and reduces mold opening costs.

[0020] Furthermore, the cutting angle of the cutting section far from the clamping section is set to be larger, while the cutting angle of the cutting section close to the clamping section is set to be smaller. This allows the cutting section with a larger cutting angle to break through the surface of the green porcelain, and then the cutting section with a smaller cutting angle to continue cutting the green porcelain. This ensures both the strength of the cutting section when cutting materials and the sharpness of the cutting section, extends the service life of the blade, and facilitates cutting.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the problem that thin blades in existing technologies can easily lead to uneven, wavy cuts, blades are typically made thicker to mitigate this defect. However, when cutting green ceramic with cavities, excessively thick blades can easily compress the cavity structure, causing severe deformation and reducing product quality. This invention provides a green ceramic hot-cutting blade that can reduce the uneven, wavy cuts that occur when cutting green ceramic, and is less likely to compress the cavity structure, thus preventing severe deformation of the green ceramic cavity structure. It also makes the cutting section less prone to breakage from the clamping section, ensuring blade quality.

[0030] It should be noted that the green ceramic hot cutting blade described in this utility model is used in, but not limited to, hot cutting machines. For ease of explanation, this utility model only uses the application of the green ceramic hot cutting blade in a hot cutting machine as an example. The principle of the green ceramic hot cutting blade in other types of equipment is essentially the same as that in the hot cutting machine, and will not be described in detail here.

[0031] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a green ceramic hot-cutting blade in one embodiment of the present invention. The green ceramic hot-cutting blade includes a clamping section 1 and a cutting section 2 connected together. The clamping section 1 is used to fix the blade holder, and its thickness is greater than that of the cutting section 2. It transitions to the cutting section 2 with a rounded corner 3 on at least one side in its thickness direction. The cutting section 2 is used to cut materials. Specifically, the end of the cutting section 2 away from the clamping section 1 cuts the material. The clamping section 1 and the cutting section 2 are flush on one side in their thickness direction and transition to each other with a rounded corner 3 on the other side. The cutting section 2 includes a plurality of sharpening segments 21 connected sequentially in the direction away from the clamping section 1. The sharpening angle of the plurality of sharpening segments 21 increases sequentially in the direction away from the clamping section 1.

[0032] When using the green ceramic hot-cutting blade provided by this utility model, the relatively thick clamping section 1 is fixed on the blade holder, and the material is cut through the relatively thin cutting section 2. Therefore, when the cutting section 2 is made thinner, the connection between the thinner cutting section 2 and the thicker clamping section 1 is achieved through a rounded corner 3. This improves the connection strength between the cutting section 2 and the clamping section 1 and reduces the stress shear area between them. This ensures that the thinner cutting section 2 still has sufficient strength to cut green ceramic, mitigating the defect of wavy, uneven edges when cutting green ceramic and making it less prone to breakage from the clamping section 1, thus guaranteeing blade quality. Furthermore, the thinner cutting section 2 is less likely to compress the cavity structure when cutting green ceramic, preventing severe deformation of the green ceramic cavity structure and improving product quality.

[0033] Meanwhile, only one side of the clamping section 1 and the cutting section 2 is set with a rounded corner 3 for transition, and the other sides of the clamping section 1 and the cutting section 2 are set flush. This ensures the connection strength between the clamping section 1 and the cutting section 2, while also effectively eliminating the shear stress area caused by the thickness difference between the clamping section 1 and the cutting section 2. This ensures the connection strength between the two, makes them less prone to breakage, facilitates molding, and reduces mold opening costs.

[0034] Furthermore, the cutting angle of the cutting section 21, which is far from the clamping section 1, is set to be larger, while the cutting angle of the cutting section 21, which is close to the clamping section 1, is set to be smaller. This allows the cutting section 21 with a larger cutting angle to break through the surface of the green porcelain, and then the cutting section 21 with a smaller cutting angle to continue cutting the green porcelain. This ensures both the strength and sharpness of the cutting section 2 when cutting materials, extends the service life of the blade, and facilitates cutting.

[0035] It should be understood that the transition fillet 3 refers to a smooth transition at the point of difference in thickness between the clamping section 1 and the cutting section 2, forming an arc-shaped concave surface. For ease of description, the portion corresponding to the transition fillet 3 between the clamping section 1 and the cutting section 2 is defined as the transition section 4.

[0036] Furthermore, it should be understood that the cutting edge angle is the angle formed by the grinding surfaces on both sides of the cutting edge, which directly affects the sharpness and durability of the tool. Generally speaking, the larger the cutting edge angle, the higher the strength of the cutting edge segment 21, and the lower the sharpness; while the smaller the cutting edge angle, the lower the strength of the cutting edge segment 21, and the higher the sharpness.

[0037] It should be noted that the number of the cutting edge 21 is not limited and can be set to two, three, four or other numbers.

[0038] Specifically, in one embodiment, please refer to Figure 4 There are two cutting sections 21. The clamping section 1 is connected to the two cutting sections 21 in sequence, and the clamping section 1 is at least one side of the clamping section 1 with the adjacent cutting section 21 at a rounded corner 3. The cutting angle of the cutting section 21 adjacent to the clamping section 1 is α1, which satisfies 1°≤α1≤2°. The cutting angle of the cutting section 21 away from the clamping section 1 is α2, which satisfies 18°≤α2≤22°.

[0039] In this embodiment, the cutting section 2 consists of two sharpened sections 21, and the clamping section 1 forms a transition fillet 3 directly with the adjacent sharpened section 21. This minimizes the number of sharpened sections 21, thereby reducing the sharpening process and saving costs, while also ensuring the cutting strength and sharpness of the cutting section 2. Preferably, in this embodiment, the sharpening angle of the sharpened section 21 adjacent to the clamping section 1 is set to 1.5°, and the sharpening angle of the sharpened section 21 farther from the clamping section 1 is set to 20°.

[0040] In one embodiment, the end of the cutting segment 2 away from the clamping segment 1 is tapered.

[0041] In this embodiment, all the multiple cutting segments 21 are set in a conical shape, and the tips of the cutting segments 21 are all located at the end furthest from the clamping segment 1, further improving the ability of the cutting segment 2 to break the material. It should be understood that the sum of the heights of the multiple cutting segments 21 should be greater than the thickness of the material, that is, the height H1 of the cutting segment 2 should be greater than the thickness of the material. And the length L of the clamping segment 1 should be greater than or equal to the outer length of the material.

[0042] In one embodiment, please refer to Figure 5 The thickness of clamping section 1 is B1, which satisfies 0.4 mm ≤ B1 ≤ 0.5 mm. The thickness of cutting section 2 is B2, which satisfies 0.1 mm ≤ B2 ≤ 0.2 mm.

[0043] In this embodiment, the thickness of clamping section 1 is controlled between 0.4 and 0.5 mm to ensure the strength of the blade during hot cutting. At the same time, the thickness of cutting section 2 is controlled between 0.1 and 0.2 mm to ensure that the cavity structure of the heated green ceramic product is not subjected to excessive compression during cutting.

[0044] It should be noted that, in this embodiment, since the cutting section 21 is tapered, in order to reduce the adverse effects of the cutting section 21 on the green porcelain cavity, the size of the end of the cutting section 2 near the transition section 4 is controlled at 0.1 to 0.2 mm.

[0045] In one embodiment, the clamping section 1 and the cutting section 2 are integrally arranged.

[0046] In this embodiment, to improve the blade strength, the clamping section 1 and the cutting section 2 are integrally formed, further enhancing the connection strength. Specifically, multiple cutting sections 21 are also integrally formed.

[0047] In one embodiment, the green ceramic hot cutting blade also includes a positioning flange (not shown), which is provided in the clamping section 1 for insertion into a positioning hole located in the blade holder.

[0048] In this embodiment, the positioning flange and the positioning hole on the tool holder allow the cutting tool to be quickly positioned on the tool holder, improving assembly convenience. At the same time, it avoids reducing the strength of the clamping section 1 by creating a positioning hole. It should be noted that the positioning flange and the clamping section 1 are integrally formed.

[0049] Furthermore, this utility model also provides a hot cutting machine, which includes the green ceramic hot cutting blade as described above. It should be noted that the detailed structure of the green ceramic hot cutting blade of the hot cutting machine can be referred to the above-described embodiments of the green ceramic hot cutting blade, and will not be repeated here. Since the above-described green ceramic hot cutting blade is used in the hot cutting machine of this utility model, the embodiments of the hot cutting machine of this utility model include all the technical solutions of all the embodiments of the above-described green ceramic hot cutting blade, and the achieved technical effects are also completely the same, and will not be repeated here.

[0050] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0051] In this design, the relatively thicker clamping section 1 is fixed to the blade holder, and the material is cut by the relatively thinner cutting section 2. Therefore, when the cutting section 2 is made thinner, the connection between the thinner cutting section 2 and the thicker clamping section 1 is improved by a rounded corner 3, reducing the stress shear area between them. This ensures that the thinner cutting section 2 still has sufficient strength to cut green porcelain, mitigating the defect of wavy, uneven edges when cutting green porcelain, and making it less prone to breakage from the clamping section 1, thus ensuring blade quality. Furthermore, the thinner cutting section 2 is less likely to compress the cavity structure when cutting green porcelain, preventing severe deformation of the green porcelain cavity structure and improving product quality.

[0052] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
