Description

Technical Field

[0001] This utility model relates to the field of alloy cutting tool technology, specifically an alloy cutting tool with an anti-chipping structure. Background Technology

[0002] A blade is a part of a knife, weapon, or machine whose edge is designed to pierce, cut, or scrape the surface of a material. Blades can be made of materials such as flint, metal (usually steel), ceramic, or others. Blades are one of the oldest tools of humankind and have been used in combat, food preparation, and other purposes. Alloy blades are a type of blade used on mechanical equipment, made by melting various metals together, and are characterized by high hardness and long service life.

[0003] A three-flute end mill for machining aluminum alloys is disclosed in publication number CN216096612U. It includes a shank, with one end extending into a cutter head. The cutter head has three spiral cutting edges rotating in the same direction at its front end. These three spiral cutting edges are evenly arranged around the axis of the shank. The core thickness of the cutter head is 42% of its outer diameter. The first tooth clearance angle of the spiral cutting edges is 13°–17°, and the second tooth clearance angle is 31°–35°. By modifying the groove design of the cutter head and increasing the first tooth clearance angle, while simultaneously modifying the core thickness to 42% of the cutter head's outer diameter, the sharpness of the tool is increased. This improves the milling efficiency of the three-flute end mill on aluminum alloys and enhances the chip removal effect, making chip removal smoother. By improving the milling efficiency and timely chip removal of aluminum alloys, it also reduces wear on the tool and workpiece caused by high temperatures due to untimely chip removal during rapid milling, prevents chipping, increases tool life, and ensures the machining accuracy of the workpiece.

[0004] Currently, alloy cutting tools are widely used in various cutting and milling operations. To improve cutting efficiency, the cutting edge is usually sharpened to a higher level, and the tool thickness is minimized. The aim is to enhance sharpness by reducing the contact area with the material. However, while this design improves cutting efficiency to some extent, it also brings significant side effects, namely, a significant reduction in the service life of the alloy cutting tool. When the cutting edge encounters a material with high hardness, or during prolonged use, alloy cutting tools are prone to chipping, including edge breakage and curling. These issues directly affect the accuracy of cutting and milling operations, resulting in burrs on the machined material surface and deviations from the expected milling results, thereby increasing material waste and defect rate. When the aforementioned three-flute end mill for aluminum alloy machining was improved, the chip removal structure was optimized to successfully avoid wear and chipping caused by high heat generated by friction on the cutting edge. Nevertheless, the reinforcement effect of the cutting edge is still not satisfactory. Therefore, when the cutting edge contacts the material, curling and breakage still occur.

[0005] Therefore, those skilled in the art have provided an alloy cutting tool with an anti-chipping structure to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide an alloy cutting tool with an anti-chipping structure to solve the problem of chipping that occurs in existing alloy cutting tools during use, as mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An alloy cutting tool with a chip-resistant structure includes: a cutting shaft, a cutting head fixedly connected to one end of the cutting shaft, a chip removal groove fixedly formed on the surface of the cutting head, a stepped cutting edge fixedly formed on the outer edge of the chip removal groove, a reinforced cutting edge mounted on the surface of the stepped cutting edge, a streamlined cutting edge formed on the surface of the reinforced cutting edge, and a fixing screw threadedly connected to the middle of the surface of the reinforced cutting edge.

[0009] As a further improvement of this utility model: a conical surface is provided at the middle of the top of the cutter head, and the cross-sectional structure of the conical surface is conical.

[0010] As a further improvement of this utility model: the stepped cutting edge and the chip removal groove are integrated, and the stepped cutting edge is distributed in a stepped shape along the outer edge of the chip removal groove.

[0011] As a further improvement of this utility model, the reinforced blade and the stepped blade edge are configured in a one-to-one correspondence.

[0012] As a further improvement of this utility model, the reinforced blade is fixedly connected to the stepped blade edge by fixing screws.

[0013] As a further improvement of this utility model, the chip removal grooves are distributed in a ring about the symmetrical center line of the cutter head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] A stepped cutting edge is designed at the outermost edge of the chip evacuation groove. This stepped edge design helps to disperse the load during the cutting process, thereby effectively reducing the concentration of local stress. This design not only helps to suppress vibration and tool chatter, but also significantly improves the machining quality of the tool tip surface. The stepped structure promotes rapid material volume breakage by increasing the number of free surfaces, which is beneficial for reducing cutting forces and energy consumption. In addition, the designed chip evacuation groove effectively avoids the accumulation of waste chips, thus maintaining a smooth machining process. A reinforced cutting edge is also specially installed on the surface of the stepped cutting edge. The purpose of reinforcing the cutting edge is to increase the thickness and hardness of the stepped cutting edge, thereby improving the overall strength of the chip groove cutting edge. This reinforcement measure can effectively prevent chipping and rolling of the cutting edge during milling. To further improve the performance of the cutting edge, the surface of the reinforced cutting edge is designed to be streamlined. This design not only reduces the frictional resistance between the cutting head and the workpiece, making the cutting process smoother, but also reduces energy consumption. The streamlined cutting edge design can also guide the chips to flow in a specific direction, effectively avoiding secondary tool jamming caused by chip accumulation, and further improving the strength and durability of the cutting head.

[0022] 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.

[0023] Please see Figures 1-5 This utility model embodiment provides an alloy cutting tool with an anti-chipping structure, including: a cutting shaft 1, a cutting head 2 fixedly connected to one end of the cutting shaft 1, and a conical surface 7 provided in the middle of the top of the cutting head 2, the cross-sectional structure of the conical surface 7 being conical;

[0024] Specifically, the design of the cutter head 2 adopts a conical surface 7 structure. This structure uses the concave conical surface 7 to adjust the tilt angle of the top of the cutter head 2. The purpose of this design is to prevent the obtuse angle of the cutter head 2 from being too small and to maintain a large sharpness. In this way, the wear and chipping of the cutter head 2 caused by excessive sharpness during use are effectively reduced, thereby extending the service life of the tool.

[0025] The surface of the cutter head 2 is fixedly provided with a chip removal groove 3, the outer edge of the chip removal groove 3 is fixedly provided with a stepped cutting edge 8, a reinforced cutting edge 4 is installed on the surface of the stepped cutting edge 8, the surface of the reinforced cutting edge 4 is provided with a streamlined cutting edge 6, and a fixing screw 5 is threadedly connected to the middle of the surface of the reinforced cutting edge 4.

[0026] The stepped cutting edge 8 and the chip removal groove 3 are integrated, and the stepped cutting edge 8 is distributed in a stepped shape along the outer edge of the chip removal groove 3. The reinforced cutting edge 4 is set one-to-one with each step of the stepped cutting edge 8. The reinforced cutting edge 4 is fixedly connected to the stepped cutting edge 8 by fixing screws 5. The chip removal groove 3 is distributed in a ring about the symmetrical center line of the cutter head 2.

[0027] Specifically, the combination of the chip removal groove 3 and the stepped cutting edge 8 allows the chip removal groove 3 to be arranged in a spiral pattern on the surface of the cutter head 2. This arrangement effectively utilizes the chip removal groove 3 for chip removal. The stepped cutting edge 8 employs a unique stepped structure design. This design, through the use of a stepped structure, effectively disperses the load generated during cutting, thereby reducing the concentration of local stress. The stepped structure design does more than just this; it also greatly promotes the rapid breakage of material volume by increasing the number of free surfaces. This not only helps reduce cutting forces but also reduces energy consumption in actual milling operations. During the process, waste chips are smoothly discharged from the chip removal groove 3 and the stepped cutting edge 8. In order to further enhance the strength of the stepped cutting edge 8, a reinforced cutting edge 4 is fixedly installed on the stepped cutting edge 8 by fixing screws 5. The addition of the reinforced cutting edge 4 will increase the thickness of the cutting edge during the milling process of the cutter head 2, effectively preventing chipping and rolling. In addition, the surface of the reinforced cutting edge 4 is also provided with a streamlined cutting edge 6. When the cutter head 2 is used, this streamlined structure can guide the waste chips to be smoothly discharged along the streamlined structure. At the same time, the streamlined cutting edge 6 can better fit the spiral design of the chip removal groove 3, which makes them more efficient and smooth when working with the cutter head 2 to achieve milling.

[0028] The working principle of this utility model is as follows:

[0029] When using this invention, the workpiece to be processed is placed under the cutting tool, the machine tool is started, and the cutting shaft 1 drives the cutting head 2 to rotate. When the cutting head 2 contacts the workpiece surface, the stepped cutting edge 8 first performs preliminary cutting. Due to the stepped structure design of the stepped cutting edge 8, the load generated during the cutting process can be effectively dispersed, reducing the concentration of local stress. At the same time, the chip removal groove 3 allows the waste chips generated during the cutting process to be discharged smoothly, avoiding the accumulation of waste chips from affecting the cutting effect. As the cutting progresses, the reinforced cutting edge 4 begins to play its role. Its increased cutting edge thickness effectively prevents chipping and rolling, ensuring the stability and accuracy of the cutting. Meanwhile, the streamlined cutting edge 6 design further enhances the waste chip discharge effect, making the cutting process more efficient and smooth. Throughout the cutting process, the wear of the cutting tool is greatly reduced, and its service life is significantly extended.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
