Description

Technical Field

[0001] The utility model relates to an alloy blade, in particular to an alloy blade with a multi-angle composite chip-breaking platform, belonging to the technical field of milling cutters. Background Technique

[0002] In the field of metal cutting machining, as a key component, the performance of an alloy blade has a crucial impact on machining quality, efficiency and cost.

[0003] In the prior art, for the alloy blade disclosed in the publication number CN208034884U, by adopting a wear-resistant alloy head as the cutting edge of the blade, its wear resistance is improved, so as to extend the service life and reduce the use cost. And in the utility model, the alloy head is only arranged at the edge part, and the usage amount of the wear-resistant alloy material is less, and the manufacturing cost is lower. In the utility model, the "乛" - shaped end face of the alloy head is in close contact with and welded to the main body of the cutter head, and the lower end face of the alloy head is welded to the blade matrix, ensuring the firm connection of the overall structure of the alloy head, the cutter head main body and the blade matrix. However, in the prior art, the cutter teeth of the alloy blade adopt an integral forming structure. Although this structure can ensure certain strength and cutting performance during the initial use, there are obvious defects. Once the cutter teeth are worn due to long-term friction with the workpiece and bearing the cutting force during the cutting process, since the cutter teeth are inseparable from the blade body, it is impossible to replace a single worn cutter tooth targeted, and only the whole alloy blade can be discarded, resulting in waste of resources and a significant increase in machining cost. At the same time, during the cutting process, the chips cannot be effectively broken and discharged smoothly, and will be wound around the tool and the workpiece, not only affecting the machining surface quality, causing problems such as surface scratches and increased roughness. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-angle composite chip-breaking platform alloy blade for solving the problems that the cutter teeth of the blade are not convenient to replace and the waste chip treatment effect in the machining process is poor.

[0005] The utility model realizes the above purpose through the following technical solutions: a multi-angle composite chip-breaking platform alloy blade, including a blade body; a plurality of mounting components are arranged on the outer peripheral surface of the blade body; the mounting component includes a first connection hole, a long rod bolt, a cutter tooth, a mounting groove and a second connection hole. The mounting grooves are arranged in a circular array on the outer peripheral surface of the blade body, the first connection holes are opened on the surface of the blade body, two second connection holes are opened on the surface of the cutter tooth, the first connection hole is in threaded connection with the long rod bolt, the second connection hole is in sliding connection with the long rod bolt, and the cutter tooth is fixedly connected to the mounting groove through the long rod bolt;

[0006] A chip-breaking component is arranged on one side of each cutter tooth, and the chip-breaking component includes a first chip-breaking platform and a second chip-breaking platform, and both the first chip-breaking platform and the second chip-breaking platform are arranged on the cutting edge of the cutter tooth.

[0007] As a further improvement of this utility model, a mounting hole is provided on the surface of the blade body at the center position.

[0008] As a further improvement of this utility model: each mounting slot is fixedly connected with a positioning block, and one side surface of each cutting tooth is provided with a matching positioning groove. The cutting tooth is installed in the mounting slot through the cooperation of the positioning groove and the positioning block.

[0009] As a further improvement of this utility model, a cutting edge is provided at the front end face of the cutting edge of the blade.

[0010] As a further embodiment of this utility model: a first chip-breaking groove is provided between the cutting edge and the second chip-breaking platform on the cutting edge of the cutting tooth, and a second chip-breaking groove is provided between the second chip-breaking platform and the first chip-breaking platform on the cutting edge of the cutting tooth.

[0011] As a further improvement of this utility model, a chip removal groove is provided on one side of the tooth surface located on the first chip breaking stage.

[0012] As a further improvement of this utility model: the surfaces of the first chip breaker and the second chip breaker are respectively provided with a number of bending structures, and the bending structures cooperate with each other to form multiple chip breaker edges with different angles.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of an installation component, allows for convenient installation. First, the cutting teeth are placed in the installation groove, with the second connecting hole on the cutting teeth roughly aligned with the first connecting hole on the blade body. Next, a long bolt is passed through the second connecting hole of the cutting teeth and threaded into the first connecting hole of the blade body. During this process, because the second connecting hole and the long bolt are slidably connected, the position of the cutting teeth can be flexibly adjusted until the optimal installation state is achieved. Finally, the long bolt is tightened, thus securely installing the cutting teeth onto the blade body. This makes the installation and removal of the cutting teeth relatively convenient. When the cutting teeth become worn or damaged, they can be easily replaced by unscrewing the long bolt without replacing the entire blade body, reducing operating costs.

[0015] 2. This utility model is equipped with a chip-breaking component. During the cutting process, when the chips flow out, they first come into contact with the first chip-breaking stage. The first chip-breaking stage applies an initial bending force to the chips, causing them to begin to undergo plastic deformation and initially change their flow direction. Then, the chips continue to move to the second chip-breaking stage. Based on the action of the first chip-breaking stage, the second chip-breaking stage further compresses and bends the chips. By utilizing the different angles, heights, or shapes of the two stages, a composite chip-breaking effect is formed, making the chips easier to break under this dual action. This effectively avoids the generation of continuous long chips. It not only prevents chips from wrapping around the tool or workpiece, avoiding scratches on the machined surface and affecting machining accuracy and surface quality, but also reduces cutting force fluctuations caused by chip accumulation, reduces tool wear, and extends tool life, thereby significantly improving the stability and efficiency of cutting.

[0016] 3. This utility model, by setting a positioning block and a positioning groove, allows for quick initial positioning during installation. Simply align the positioning groove of the cutting tooth with the positioning block in the mounting groove and gently push it in. No repeated adjustments are needed, making the operation simple and efficient. This ensures consistent positioning of the cutting teeth each time, guaranteeing the positional accuracy of the cutting edge of each tooth during batch tooth replacements. This maintains the stability of the overall cutting performance of the blade, thereby improving machining accuracy, reducing machining errors, and producing products with more precise dimensions and more stable quality. Simultaneously, the tight fit between the positioning block and the positioning groove acts like double insurance for the cutting teeth, strengthening the stability of the tooth installation. During cutting, the cutting teeth can withstand greater cutting forces without displacement or wobbling, effectively preventing cutting abnormalities caused by loose teeth, reducing the risk of tool damage, extending the service life of the cutting teeth and the blade body, reducing production costs, and improving processing efficiency and economic benefits.

[0017] 4. This utility model, by setting a first chip breaker groove and a second chip breaker groove, ensures that when the tool performs cutting operations, the chips generated by the cut material first come into contact with the first chip breaker groove. Due to the special geometry of the first chip breaker groove, it applies a force to the chips, causing them to begin curling and deforming at this stage. As the chips continue to move forward and reach the second chip breaker groove, the second chip breaker groove further bends and compresses the chips, intensifying the deformation, and then the chips enter the second chip breaker groove. The second chip breaker further alters the flow direction and deformation pattern of the chips. Through its synergistic effect with the second and first chip breaker stages, the chips undergo repeated deformation under multiple forces, ultimately breaking into smaller segments more easily. This design, with chip breaker channels strategically positioned between the cutting edge, the first chip breaker stage, and the second chip breaker stage, effectively addresses the machining requirements of different materials and cutting parameters. It significantly improves chip breaking performance, prevents chips from entangled in the workpiece and tool, ensures stable and efficient machining, enhances machining accuracy and surface quality, reduces tool wear, and extends tool life.

[0018] 5. By incorporating a chip removal groove, this invention utilizes the centrifugal force generated by the rotating tool to quickly guide broken chips away from the machining area during cutting. This prevents chip accumulation in the machining area and avoids secondary chipping of the workpiece, thereby ensuring the quality of the machined surface, reducing surface roughness, and improving machining accuracy. Simultaneously, timely chip removal reduces wear on the tool's cutting edge, preventing abnormal increases in cutting force due to chip blockage. This extends the service life of the cutting teeth and even the entire alloy insert, improving machining efficiency and stability, and reducing processing costs.

[0019] 6. The surfaces of the first and second chip breaker stages of this utility model are respectively provided with several bending structures. The chip breaker edges at different angles can apply forces to the chips from multiple directions, making the chips easier to break under complex forces, effectively meeting the chip breaking requirements under various materials and cutting parameters.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0031] like Figures 1 to 9 As shown, a multi-angle composite chip breaker alloy blade includes a blade body 1. Several mounting components are provided on the outer circumferential surface of the blade body 1. Each mounting component includes a first connecting hole 3, a long bolt 4, a cutting tooth 5, a mounting groove 6, and a second connecting hole 8. The mounting groove 6 is arranged in a circular array on the outer circumferential surface of the blade body 1. The first connecting hole 3 is located on the surface of the blade body 1. Two second connecting holes 8 are located on the surface of the cutting tooth 5. The first connecting hole 3 is threadedly connected to the long bolt 4, and the second connecting hole 8 is slidably connected to the long bolt 4. The cutting tooth 5 is fixedly connected to the mounting groove 6 via the long bolt 4. During installation, the cutting tooth 5 is first placed in the mounting groove 6, so that the second connecting hole 8 on the cutting tooth 5 is approximately aligned with the first connecting hole 3 on the blade body 1. Then, the long bolt 4 is passed through the second connecting hole 8 of the cutting tooth 5 and threadedly connected to the first connecting hole 3 of the blade body 1. During this process, since the second connecting hole 8 and the long rod bolt 4 are slidably connected, the position of the cutting tooth 5 can be flexibly adjusted until the optimal installation state is achieved. Finally, the long rod bolt 4 is tightened to securely install the cutting tooth 5 on the blade body 1, making the installation and removal of the cutting tooth 5 more convenient. When the cutting tooth 5 is worn or damaged, it can be easily replaced by unscrewing the long rod bolt 4 without replacing the entire blade body 1, thus reducing the cost of use.

[0032] Each cutting tooth 5 is provided with a chip breaker assembly on one side, which includes a first chip breaker 13 and a second chip breaker 14. Both the first chip breaker 13 and the second chip breaker 14 are located on the cutting edge of the cutting tooth 5. During the cutting process, when the chip flows out, it first contacts the first chip breaker 13. The first chip breaker 13 applies an initial bending force to the chip, causing the chip to begin to undergo plastic deformation and initially change its flow direction. Then, the chip continues to move to the second chip breaker 14. Based on the action of the first chip breaker 13, the second chip breaker 14 further squeezes and bends the chip. By using the different angles, heights, or shapes of the two, a composite chip breaker effect is formed, making the chip easier to break under this dual action. This effectively avoids the generation of continuous long chips. It not only prevents chips from wrapping around the tool or workpiece, avoiding scratches on the machined surface and affecting machining accuracy and surface quality, but also reduces cutting force fluctuations caused by chip accumulation, reduces tool wear, and extends tool life, thereby significantly improving the stability and efficiency of the cutting process. Example 2

[0033] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] Furthermore, a mounting hole 2 is provided on the surface of the blade body 1 at the center position. Through the mounting hole 2, the alloy blade can be accurately and securely installed on the tool holder or tool disc, etc., using special fastening bolts or other connecting parts.

[0035] Furthermore, each mounting slot 6 is fixedly connected to a positioning block 7, and one side surface of each cutting tooth 5 is provided with a matching positioning groove 9. The cutting tooth 5 is installed in the mounting slot 6 through the cooperation of the positioning groove 9 and the positioning block 7. During installation, the positioning groove 9 of the cutting tooth 5 is aligned with the positioning block 7 in the mounting slot 6, and gently pushed in to quickly complete the initial positioning without repeated adjustments. The operation is simple and efficient, ensuring that the installation position of the cutting tooth 5 is highly consistent each time. When replacing cutting teeth 5 in batches, the positional accuracy of the cutting edge of each cutting tooth 5 can be guaranteed, maintaining the stability of the overall cutting performance of the blade, thereby improving machining accuracy, reducing machining errors, and producing products with more precise dimensions and more stable quality. At the same time, the positioning block 7 and the positioning groove 9 fit tightly, like double insurance for the cutting tooth 5, strengthening the stability of the installation of the cutting tooth 5. During cutting, the cutting tooth 5 can withstand greater cutting forces without displacement or shaking, effectively avoiding cutting abnormalities caused by loosening of the cutting tooth 5, reducing the risk of tool damage, extending the service life of the cutting tooth 5 and the blade body 1, reducing production costs, and improving machining efficiency and economic benefits.

[0036] Furthermore, a cutting edge 15 is provided at the front end face of the cutting edge of the cutting tooth 5 for milling the workpiece. Example 3

[0037] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0038] Furthermore, a first chip breaker groove 10 is provided between the cutting edge 15 and the second chip breaker 14 on the cutting edge of the cutting tooth 5, and a second chip breaker groove 11 is provided between the second chip breaker 14 and the first chip breaker 13 on the cutting edge of the cutting tooth 5. When the tool performs cutting operations, the chips generated by the material being cut flow out and first come into contact with the first chip breaker groove 10. Due to the special geometry of the first chip breaker groove 10, it applies a force to the chips, causing the chips to begin to curl and deform at this stage. As the chips continue to move forward, when they reach the second chip breaker groove 14, based on the deformation that occurred at the first chip breaker groove 10, the second chip breaker groove 14 continues to bend and compress the chips, allowing them to curl and deform. The deformation of the chips intensifies, and then the chips enter the second chip breaker groove 11. The second chip breaker groove 11 further changes the flow direction and deformation mode of the chips. Through its synergistic effect with the second chip breaker stage 14 and the first chip breaker stage 13, the chips are repeatedly deformed under the action of multiple forces, making them easier to break into small segments. This design of rationally arranging chip breaker grooves between the cutting edge 15, the first chip breaker stage 13 and the second chip breaker stage 14 can effectively cope with the processing requirements of different materials and different cutting parameters, significantly improve the chip breaking effect, prevent chips from entangled in the workpiece and tool, ensure stable and efficient cutting processing, improve processing accuracy and surface quality, reduce tool wear and extend tool life.

[0039] Furthermore, a chip removal groove 12 is provided on one side of the surface of the cutting tooth 5 on the first chip breaking stage 13. During cutting, the chip removal groove 12 can quickly guide the broken chips away from the machining area by means of the centrifugal force generated by the rotation of the cutting tool, avoiding the accumulation of chips in the machining area and preventing the chips from cutting the workpiece again. This ensures the quality of the machined surface, reduces surface roughness, and improves machining accuracy. At the same time, timely chip removal can reduce the wear of chips on the cutting edge of the cutting tool, avoid abnormal increase in cutting force due to chip blockage, and thus extend the service life of the cutting tooth 5 and even the entire alloy insert, improve the efficiency and stability of cutting, and reduce machining costs.

[0040] Furthermore, the surfaces of the first chip breaker 13 and the second chip breaker 14 are respectively provided with several bending structures. The bending structures cooperate with each other to form multiple chip breaker edges at different angles. The chip breaker edges at different angles can apply forces to the chips from multiple directions, making the chips easier to break under the action of complex forces, effectively meeting the chip breaking requirements under various materials and cutting parameters.

[0041] Working principle: When using this type of alloy insert for milling, first, place the insert body 1 stably on the operating table. Its outer circumference has a circular array of mounting slots 6. Pick up the cutting tooth 5, align the positioning slot 9 of the cutting tooth 5 with the positioning block 7 in the mounting slot 6, and gently push it in to achieve precise positioning. This places the cutting tooth 5 into the mounting slot 6, making the two second connecting holes 8 on the cutting tooth 5 approximately aligned with the first connecting hole 3 on the insert body 1. Then, insert a long bolt 4 through the second connecting hole 8 of the cutting tooth 5. Because the two are slidably connected, the position of the cutting tooth 5 can be flexibly adjusted to the optimal state. Finally, use a tool to tighten the long bolt 4, ensuring a tight threaded connection with the first connecting hole 3, thus completing the fixing process.

[0042] In use, the alloy insert is securely mounted on the tool holder or tool head via the mounting hole 2 at the center of the insert body 1 using specialized fastening bolts or other connectors. The machining equipment is started, and the cutting edge 15 on the cutting edge face of the cutting tooth 5 begins milling the workpiece. The chips generated during cutting first contact the first chip breaker groove 10 and begin to curl and deform under its special geometry. Then, the chips reach the second chip breaker stage 14, where they are further bent and compressed on top of the previous deformation, intensifying the deformation. Subsequently, the chips enter the second chip breaker groove 11, where their flow direction and deformation mode are changed again, working in conjunction with the second chip breaker stage 14 and the first chip breaker stage 13. During this process, the bending structure on the surface of the chip breaker stage forms multi-angle chip-breaking edges, applying force to the chips from multiple directions, making them easier to break. Finally, the chip removal groove 12, using the centrifugal force of the rotating tool, quickly guides the broken chips away from the machining area.

[0043] When the wear of the cutting tooth 5 affects the machining process, use a tool to unscrew the long bolt 4. Due to the connection characteristics, the worn cutting tooth 5 can be easily removed. After removing the cutting tooth 5, repeat the above installation steps to complete the replacement.

[0044] This utility model features a convenient and precise cutting tooth 5, ensuring accurate cutting edge positioning during batch replacements and maintaining stable cutting performance. Since only the cutting tooth 5 needs to be replaced, it significantly reduces operating costs. Simultaneously, the chip breaker groove and chip breaker platform work together, with multi-angle chip breaker edges, to significantly improve chip breaking effect, prevent chip entanglement, ensure stable and efficient machining, reduce tool wear, and extend tool life. The chip removal groove 12 quickly removes chips, avoiding chip accumulation and secondary cutting, ensuring surface quality, improving machining accuracy, reducing cutting edge wear, and enhancing machining efficiency and stability.
