Description

Technical Field

[0001] This utility model relates to the field of daily consumables technology, and in particular to a cutting machine cutting board. Background Technology

[0002] Cutting machines are widely used in daily production, and their accompanying cutting boards, as one of the key consumables, play a vital role in supporting and positioning workpieces. Currently, most cutting machine cutting boards on the market are of one-piece structure and are usually made of engineering plastics such as nylon. Although nylon is a low-cost material, its material properties are unstable. Especially under the condition of continuous high-speed rotation of the saw blade, the kerf on the cutting board is prone to widening rapidly due to wear, resulting in a significant reduction in the cutting board's service life.

[0003] Furthermore, in actual use, only specific areas of the existing cutting board (such as near the saw kerf) experience major wear, while the entire board remains intact. However, because it is a single piece, once a part is damaged, the entire cutting board needs to be replaced, resulting in material waste and increased operating costs. At the same time, frequent replacements of the entire cutting board not only increase the company's material expenses but also affect the continuity and efficiency of the production line.

[0004] Therefore, there is an urgent need in this field for a cutting board solution that is structurally sound, has a long service life, is easy to replace, and is less expensive, in order to solve the above-mentioned problems in the prior art. Summary of the Invention

[0005] The purpose of this utility model is to provide a cutting board for a cutting machine to achieve at least one of the following objectives: 1) Ensure the rationality and stability of the modified structure; 2) To address the issue of cutting boards having a shortened lifespan due to unstable materials; 3) To solve the problem of having to replace the entire cutting board every time you change it; 4) The design and invention of the cutting board should allow for replacement of only the small board without changing the frame.

[0006] To achieve the above objectives, the following technical solution is adopted: A cutting board includes a bottom frame, a bakelite board, and assembly bolts; wherein, the bottom frame is provided with a mounting groove, the mounting groove is provided with a plurality of first threaded holes, the mounting groove is provided with a hollow in the middle, the bakelite board is provided with a plurality of second threaded holes, the number of the second threaded holes being the same as the number of the first threaded holes, and the bakelite board is detachably assembled to the bottom frame by means of the assembly bolts engaging with the first threaded holes and the second threaded holes.

[0007] Preferably, in the above-mentioned cutting machine anvil, the bakelite board includes a first plate and a second plate. The first plate is provided with a plurality of second threaded holes. The second plate is fixedly disposed at one end of the first plate. When the bakelite board is assembled to the bottom frame by means of the assembly bolts and the first and second threaded holes, the second plate fills the hollow.

[0008] Preferably, in the above-mentioned cutting machine cutting board, the material of the bottom frame is selected from aluminum alloy, stainless steel, carbon steel and engineering composite materials.

[0009] Preferably, in the above-mentioned cutting machine anvil, both the first threaded hole and the second threaded hole are provided with metal tooth sleeves.

[0010] Preferably, in the above-mentioned cutting machine anvil, the number of the first threaded hole and the second threaded hole are both set to 6.

[0011] Preferably, in the above-mentioned cutting machine anvil, the geometric center of the hollowed-out part overlaps with the geometric center of the mounting groove.

[0012] Preferably, in the above-mentioned cutting machine cutting board, the area ratio of the second plate to the area of ​​the bottom frame is 1:3 to 1:6.

[0013] Preferably, in the above-mentioned cutting machine anvil, the bottom frame is also provided with mounting holes.

[0014] The beneficial effects of this utility model are: This invention employs a split structure where the bottom frame and bakelite board are detachably connected. By utilizing assembly bolts that engage with the first threaded hole on the frame and the second threaded hole on the small plate, it enables rapid, localized replacement of worn parts of the cutting board, significantly extending the overall lifespan of the cutting board and drastically reducing material costs. Simultaneously, the excellent wear resistance of the bakelite board extends its lifespan several times compared to traditional nylon cutting boards, while the reusable frame structure maximizes material utilization and reduces waste. Ultimately, while ensuring the structural stability and applicability of the cutting board, it comprehensively achieves multiple beneficial effects: cost savings, increased replacement efficiency, and improved product quality.

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] This utility model embodiment provides a cutting machine cutting board, such as Figures 1 to 4 As shown, the cutting board includes a bottom frame 1, a bakelite board 2, and assembly bolts 3. The bottom frame 1 is provided with a mounting groove 101, and the mounting groove 101 is provided with a plurality of first threaded holes 102. The mounting groove 101 has a hollow 103 in the middle. The bakelite board 2 is provided with a plurality of second threaded holes 201, the number of second threaded holes 201 being the same as the number of first threaded holes 102. The bakelite board 2 is detachably assembled to the bottom frame 1 by means of the assembly bolts 3 and the first threaded holes 102 and second threaded holes 201.

[0023] Specifically, the bottom frame 1 serves as the main support structure, and its shape matches the workbench of the cutting machine to ensure the overall installation applicability and stability of the modified cutting board. The mounting groove 101 supports and positions the bakelite board 2, ensuring that it will not shift during use. The cutout 103 is located in the middle of the mounting groove 101, providing space for the saw blade of the cutting machine to pass through, while avoiding accidental wear of the saw blade by the frame material, thus concentrating the effective working area of ​​the cutting board on the bakelite board 2. The first threaded hole 102 preferably has a metal thread sleeve embedded in it. This design can effectively improve the wear resistance and peel resistance of the threads, significantly extending the service life of the frame under frequent disassembly and assembly.

[0024] The bakelite board 2, as a vulnerable component directly bearing the cutting operation, is made of stable bakelite material. This material has characteristics such as high mechanical strength, good wear resistance, and low water absorption, and its service life can be increased several times compared to traditional nylon cutting boards. The second threaded hole 201 corresponds one-to-one with the first threaded hole 102 on the bottom frame 1, together forming a connection channel for mating with the assembly bolt 3.

[0025] The assembly bolts 3, acting as connectors, pass sequentially through the second threaded holes 201 on the bakelite board 2 and are finally screwed into the first threaded hole 102 of the bottom frame 1, thereby firmly pressing and fixing the bakelite board 2 into the mounting groove 101 of the bottom frame 1. This detachable connection method forms the core of the modular design: when the bakelite board 2 needs to be replaced due to wear and widening of the saw kerf in its middle caused by long-term use, only the assembly bolts 3 need to be removed to remove the old bakelite board 2 from the frame and replace it with a new board, without having to replace the entire cutting board assembly. This principle enables precise replacement of consumables, maximizes the effective use area of ​​materials, greatly reduces long-term operating costs, simplifies the maintenance process, and improves replacement efficiency.

[0026] In some embodiments, such as Figure 3 As shown, the bakelite board 2 includes a first plate 202 and a second plate 203. The first plate 202 has a plurality of second threaded holes 201. The second plate 203 is fixedly disposed at one end of the first plate 202. Figure 4 As shown, when the bakelite board 2 is assembled to the bottom frame 1 by the assembly bolts 3 in conjunction with the first threaded hole 102 and the second threaded hole 201, the second plate 203 fills the hollow 103.

[0027] When the bakelite board 2 is assembled to the bottom frame 1 via the assembly bolts 3 and the first threaded hole 102 and the second threaded hole 201, the second plate 203 completely fills the hollow 103 in the middle of the mounting groove 101. The core principle of this design is that the second plate 203 constitutes the core load-bearing area of ​​the cutting board's working surface, directly bearing the impact and wear of cutting operations. Its structure, filling the hollow 103, ensures the overall flatness and continuity of the support strength of the cutting board's working surface, effectively preventing workpiece instability or cutting vibration caused by the hollow 103 of the frame. When this core load-bearing area (i.e., the second plate 203) wears down due to long-term use and needs replacement, the operator does not need to replace the entire cutting machine cutting board; they only need to remove and replace the first plate 202 and the second plate 203 as a single vulnerable module from the frame. Compared to replacing the entire cutting board, this still significantly saves on consumable costs and simplifies maintenance.

[0028] In some embodiments, the bottom frame 1 serves as the load-bearing foundation of the entire cutting board. Its material can be selected based on specific cost, working environment, and strength requirements, such as aluminum alloy, stainless steel, carbon steel, or engineering composite materials. When aluminum alloy is used, lightweight design and excellent corrosion resistance are achieved. Stainless steel is particularly suitable for humid conditions or environments with high hygiene requirements, offering optimal rust resistance. Carbon steel can meet basic strength requirements and provide some rust resistance through surface galvanizing or powder coating, making it the most economical option. Engineering composite materials (such as nylon-reinforced glass fiber) achieve overall lightweight design and excellent electrical insulation properties.

[0029] In some embodiments, metal threaded sleeves are provided inside both the first threaded hole 102 and the second threaded hole 201. These metal threaded sleeves serve as thread reinforcement elements, and their core function is to solve the problem of thread wear and stripping caused by frequent disassembly and assembly of the bolts 3. Specifically, when operators repeatedly tighten and loosen the assembly bolts 3 to replace the bakelite board 2, significant friction and mechanical stress are generated between the bolts and the threaded holes. If the first threaded hole 102 is directly machined on the substrate of the bottom frame 1 (such as aluminum alloy, engineering plastic, etc.), or the second threaded hole 201 is directly opened on the bakelite board 2, the hardness of the substrate material may not be sufficient to withstand this stress for a long time, easily leading to thread damage and causing the entire connection structure to fail. By pre-installing metal threaded sleeves inside both, all tightening force and wear are concentrated on the high-strength metal liner, effectively protecting the body threads of the bottom frame 1 and the bakelite board 2, greatly improving the durability and reliability of the entire detachable connection structure, and ensuring the stable execution of the modular replacement scheme under long-term use.

[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, the number of the first threaded hole 102 and the second threaded hole 201 is both set to six. This configuration is an optimized choice after comprehensively considering connection stability, ease of assembly and disassembly, and structural strength. Its working principle is that the six connection points can form a symmetrical and uniform force distribution around the periphery of the mounting groove 101. When tightened by the assembly bolts 3, this configuration ensures that the entire bottom surface of the bakelite board 2, especially its core working area, is smoothly and firmly pressed into the mounting groove 101 of the bottom frame 1, effectively preventing local warping or vibration caused by uneven tightening force or too few connection points. At the same time, while providing sufficient clamping force, the six threaded holes do not excessively increase the number of steps required for assembly and disassembly, maintaining the necessary convenience when replacing vulnerable parts, thus achieving the best balance between structural reliability and maintenance efficiency.

[0031] It should be noted that the setting of six first threaded holes 102 and two threaded holes 201 is merely illustrative and not a limitation on the scope of protection of this utility model. In other embodiments of this utility model, the specific number of the first threaded holes and the second threaded holes can be adaptively adjusted according to the actual size, shape, and stress requirements of the bottom frame 1 and the bakelite board 2. For example, they can be set to four, eight, or any other arbitrary number. As long as the connection strength and sealing requirements required to stably fix the bakelite board 2 to the bottom frame 1 are met, they should be considered to fall within the scope of protection of this utility model. The specific selection of the number is a conventional design change that can be made by those skilled in the art after comprehensively considering factors such as the load on the cutting board, material characteristics, and production costs.

[0032] In some embodiments, such as Figure 2 As shown, the geometric center of the hollow 103 overlaps with the geometric center of the mounting groove 101. The principle behind this centered layout is that it ensures that after the bakelite board 2 is installed to the bottom frame 1, its core working area can achieve symmetrical support relative to the entire anvil structure. When cutting is performed in the central area of ​​the anvil, this symmetrical structure allows the force to be evenly transmitted to the surrounding area through the bottom frame 1, effectively avoiding additional bending moments or torques that may be generated due to eccentric force distribution. This significantly improves the overall stability and structural strength of the anvil under cyclic impact loads, while also helping to reduce vibration and noise. It is understood that the overlap between the center of the hollow 103 and the center of the mounting groove 101 is only a preferred embodiment. In certain specific application scenarios, depending on the actual working position of the saw blade or to optimize material distribution, the hollow 103 can also be arranged eccentrically relative to the mounting groove 101. Such equivalent transformations or adaptive adjustments based on the central symmetry structure are reasonable extensions of the technical solution of this utility model.

[0033] In some embodiments, such as Figure 4As shown, the area ratio of the second plate 203 to the area of ​​the bottom frame 1 is 1:3 to 1:6. This specific area ratio range is an optimized design that has been proven in practice. Its working principle is as follows: this ratio ensures that the second plate 203, as the core vulnerable area directly bearing cutting wear, has sufficient working area to cover the main cutting operation range; at the same time, this design precisely limits the proportion of the vulnerable area in the entire anvil structure, so that the volume and material cost of the replaceable bakelite board 2 (including the first plate 202 and the second plate 203) are controlled at a level far lower than that of the overall frame. When the area ratio is greater than 1:3, the vulnerable module size is too large, and the cost-saving effect will be weakened; when the area ratio is less than 1:6, it may lead to insufficient core working area, affecting normal use. Therefore, the ratio range of 1:3 to 1:6 maximizes the reduction of consumable costs and the improvement of material utilization while ensuring functionality, which is one of the key manifestations of the economic benefits of this solution. It is understood that this area ratio range is only a preferred example, and those skilled in the art can make adaptive adjustments around this ratio range according to the needs of actual cutting conditions.

[0034] In some embodiments, such as Figure 2 As shown, the bottom frame 1 is also provided with mounting holes 104. These mounting holes 104 are typically countersunk or through holes, serving as connection points to secure the entire cutting machine anvil assembly to the cutting machine's worktable. By using dedicated mounting bolts that pass through the mounting holes 104 and engage with pre-drilled threaded holes on the cutting machine's worktable, the bottom frame 1 can be firmly locked in the correct position on the worktable. This ensures that the anvil will not shift due to cutting vibration or external impact during operation, guaranteeing the accuracy and safety of the cutting operation. The number, position, and size of the mounting holes 104 are designed to match the interface specifications of the actual cutting machine, and are typically symmetrically arranged along the frame edges to maintain balanced force. This structural feature enables the anvil assembly of this invention to be quickly adapted and reliably installed with various models of cutting machines.

[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
