Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, and in particular to a wear-resistant tool with an extended side cutting edge for side cutting. Background Technology

[0002] In modern machining, the performance and quality of cutting tools play a crucial role in improving production efficiency, ensuring machining accuracy, and reducing costs. With the increasing demands for precision and quality in industrial production, and the widespread application of various new materials, traditional cutting tools are gradually revealing some limitations in certain specific machining tasks.

[0003] 1. Tool holder: Used to connect with the machine tool spindle, transmit torque and withstand cutting force;

[0004] 2. Blade: This is the main body of the knife, usually made of high-strength and high-hardness materials;

[0005] 3. Extended edge: Located on the side edge of the blade, it is specially designed and processed to increase the length of the cutting edge, thereby improving cutting efficiency.

[0006] For example, a Chinese patent discloses a side-cutting, extended-edge, wear-resistant, and vibration-damping cutting tool (patent number: CN216729747U). This tool utilizes a circumferentially unequal-division circumferential cutting edge and a radially unequal helical angle circumferential cutting edge. This design eliminates or reduces resonance generated during rapid cutting of the workpiece. It enhances the overall strength and rigidity of the tool during high-speed rotary cutting, prevents spindle wobbling during cutting, thereby improving wear resistance and significantly improving the surface roughness of the machined parts.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, after prolonged use of the device, the tool will overheat, which will lead to a decrease in the hardness of the tool material, making it more prone to wear and deformation, thereby shortening the tool's service life, dulling the cutting edge of the tool, and reducing cutting efficiency and machining accuracy. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a side-cutting extended-edge wear-resistant tool, which solves the technical problem that prolonged use of the device can lead to tool overheating, resulting in a decrease in the hardness of the tool material, making it more prone to wear and deformation, thus shortening the tool's service life, dulling the cutting edge, and reducing cutting efficiency and machining accuracy.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A side-cutting extended-blade wear-resistant tool includes a tool holder. The top of the tool holder is provided with a turning mechanism for heat dissipation. The turning mechanism includes a tool body, a titanium nitride coating, heat dissipation holes, and heat dissipation grooves. The tool body is fixedly installed on the top of the tool holder. The titanium nitride coating is applied to the surface of the tool body. The heat dissipation holes are formed inside the tool body, and the heat dissipation grooves are formed inside the tool body.

[0011] Preferably, the blade is fixedly installed on the side wall of the blade body.

[0012] Preferably, the blade surface is provided with an aluminum oxide coating.

[0013] Preferably, a drill bit is fixedly installed on the top of the cutter body, and a handle is fixedly installed on the bottom of the cutter holder.

[0014] Preferably, a reinforcing rib is fixedly installed inside the handle, and a rubber column is fixedly installed inside the reinforcing rib.

[0015] Preferably, a base is fixedly installed at the bottom of the handle, and a discharge groove is provided on the side wall of the blade body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During prolonged use, the friction of the cutting tool will generate a significant amount of heat. The combination of heat dissipation grooves and holes increases the contact area between the air and the cutting tool, improving its heat dissipation efficiency. Furthermore, the sidewalls of the cutting tool are coated with titanium nitride. Due to its high hardness, titanium nitride can withstand friction and wear during cutting, reducing scratches and deformation on the tool surface. It is also resistant to chemical reactions with other substances at high temperatures, maintaining its structural and performance stability. Additionally, its relatively low coefficient of friction helps reduce heat generation during cutting, decreasing friction and wear between the cutting tool and the workpiece, thereby increasing the tool's service life.

[0018] II. When in use, the high-speed rotating drill bit will first enter the workpiece, and the cutting edge will process the workpiece. The surface of the cutting edge is coated with an alumina coating. The alumina coating has a high melting point and good chemical stability, which can maintain structural stability at high temperatures and is not easily decomposed or oxidized. It has high hardness, which can effectively resist wear, and low thermal conductivity, which can reduce heat transfer and play a heat insulation role, thus maintaining performance in high-temperature environments. It also has good anti-adhesive wear ability, reducing adhesion and wear with workpiece materials. In addition, the inside of the tool holder is equipped with reinforcing ribs to increase the rigidity of the internal structure of the tool holder. The rubber column will greatly absorb the resonance generated during the operation of the device, thereby helping to increase the service life of the device. Attached Figure Description

[0025] This application provides a side-cutting, extended-edge, wear-resistant cutting tool, effectively solving the problem that prolonged use of the device leads to tool overheating, resulting in a decrease in the hardness of the tool material, making it more prone to wear and deformation, thus shortening the tool's service life, dulling the cutting edge, and reducing cutting efficiency and machining accuracy. During prolonged use, the friction of the tool body generates a large amount of heat. The combination of heat dissipation grooves and holes increases the contact area between air and the tool body, improving heat dissipation efficiency. Furthermore, the sidewall of the tool body is coated with titanium nitride. Due to its high hardness, titanium nitride can withstand friction and wear during cutting, reducing scratches and deformation on the tool surface. It is also resistant to chemical reactions with other substances at high temperatures, maintaining its structural and performance stability. A relatively low coefficient of friction helps reduce heat generation during cutting, decreasing friction and wear between the tool body and the workpiece, thus increasing the tool's lifespan. Upon initial use, the high-speed rotating drill bit first penetrates the workpiece, and the cutting edge processes it. The cutting edge surface is coated with an alumina layer, which has a high melting point and good chemical stability, maintaining structural stability at high temperatures and resisting decomposition or oxidation. Its high hardness effectively resists wear, and its low thermal conductivity reduces heat transfer, providing insulation and maintaining performance in high-temperature environments. It also possesses excellent anti-adhesive wear capabilities, reducing adhesion and wear to the workpiece material. Furthermore, reinforcing ribs inside the tool holder increase the rigidity of the internal structure, and rubber pillars significantly absorb resonance generated during operation, further extending the tool's lifespan.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that prolonged use of the device leads to overheating of the tool, resulting in a decrease in the hardness of the tool material, making it more prone to wear and deformation, thereby shortening the tool's service life, dulling the cutting edge, and reducing cutting efficiency and machining accuracy. The overall concept is as follows: A side-cutting extended-edge wear-resistant tool includes a tool holder 11. The top of the tool holder 11 is provided with a turning mechanism for easy heat dissipation. The turning mechanism includes a tool body 12, a titanium nitride coating 13, heat dissipation holes 16, and heat dissipation grooves 24. The tool body 12 is fixedly installed on the top of the tool holder 11. The titanium nitride coating 13 is applied to the surface of the tool body 12. The heat dissipation holes 16 are opened inside the tool body 12, and the heat dissipation grooves 24 are opened on the tool body 12. 2. Internally, during prolonged use, friction of the cutting tool 12 will generate a large amount of heat. The cooperation between the heat dissipation groove 24 and the heat dissipation hole 16 increases the contact area between the air and the cutting tool 12, thereby improving the heat dissipation efficiency of the cutting tool 12. Furthermore, the side wall of the cutting tool 12 is provided with a titanium nitride coating 13. Due to its high hardness, the titanium nitride coating 13 can withstand friction and wear during the cutting process, reducing scratches and deformation on the surface of the cutting tool 12. In high-temperature environments, it is not prone to chemical reactions with other substances, thus maintaining its structural and performance stability. Moreover, the surface has a relatively low coefficient of friction, which helps to reduce heat generation during the cutting process and reduce friction and wear between the cutting tool 12 and the workpiece, thereby increasing the service life of the cutting tool 12.

[0028] A cutting edge 14 is fixedly installed on the side wall of the cutter body 12. The surface of the cutting edge 14 is coated with an alumina coating 15. A drill bit 17 is fixedly installed on the top of the cutter body 12. A handle 18 is fixedly installed on the bottom of the cutter holder 11. A reinforcing rib 19 is fixedly installed inside the handle 18. A rubber column 21 is fixedly installed inside the reinforcing rib 19. A base 22 is fixedly installed on the bottom of the handle 18. When the device is put into use, the high-speed rotating drill bit 17 will first enter the workpiece. The cutting edge 14 will process the workpiece. The surface of the cutting edge 14 is coated with an alumina coating 15. The alumina coating 15 has a high melting point and good chemical stability, which can maintain structural stability at high temperatures and is not easily decomposed or oxidized. It has high hardness, which can effectively resist wear. It also has low thermal conductivity, which can reduce heat transfer and play a heat insulation role, thereby maintaining performance in high-temperature environments. It also has good anti-adhesive wear ability, reducing adhesion and wear with workpiece materials. The reinforcing rib 19 is set inside the handle 18 to increase the rigidity of the internal structure of the handle 18. The rubber column 21 will greatly absorb the resonance generated during the operation of the device, thereby helping to increase the service life of the device.

[0029] The side wall of the cutter body 12 is provided with a discharge groove 23, which helps to smoothly discharge the chips generated during the cutting process, prevents chip blockage, and avoids affecting the machining accuracy and tool life.

[0030] To address the problems existing in the prior art, this utility model provides a side-cutting, extended-blade, wear-resistant cutting tool. During prolonged use, the tool body 12 generates significant heat due to friction. The cooperation between the heat dissipation grooves 24 and 16 increases the contact area between the air and the tool body 12, improving its heat dissipation efficiency. Furthermore, the sidewall of the tool body 12 is coated with a titanium nitride coating 13. Due to its high hardness, the titanium nitride coating 13 can withstand friction and wear during cutting, reducing scratches and deformation on the surface of the tool body 12. It is also resistant to chemical reactions with other substances at high temperatures, maintaining its structural and performance stability. Additionally, its relatively low coefficient of friction helps reduce heat generation during cutting and decreases friction between the tool body 12 and the workpiece. Friction and wear between the parts increase the service life of the cutter body 12. When it is first used, the high-speed rotating drill bit 17 will first enter the workpiece, and the cutting edge 14 will process the workpiece. The surface of the cutting edge 14 is coated with an alumina coating 15. The alumina coating 15 has a high melting point and good chemical stability, which can maintain structural stability at high temperature and is not easily decomposed or oxidized. It has high hardness, which can effectively resist wear, and low thermal conductivity, which can reduce heat transfer and play a heat insulation role, thus maintaining performance in high temperature environment. It also has good anti-adhesive wear ability, reducing adhesion and wear with workpiece material. In addition, the tool holder 18 is provided with reinforcing ribs 19 to increase the rigidity of the internal structure of the tool holder 18. The rubber column 21 will greatly absorb the resonance generated during the operation of the device, thereby helping to increase the service life of the device.

[0044] Working principle:

[0045] Firstly, during prolonged use, the friction of the cutting tool 12 will generate a large amount of heat. The cooperation between the heat dissipation groove 24 and the heat dissipation hole 16 increases the contact area between the air and the cutting tool 12, thereby improving the heat dissipation efficiency of the cutting tool 12. Furthermore, the side wall of the cutting tool 12 is provided with a titanium nitride coating 13. Due to its high hardness, the titanium nitride coating 13 can withstand the friction and wear during the cutting process, reducing scratches and deformation on the surface of the cutting tool 12. In high-temperature environments, it is not prone to chemical reactions with other substances, thus maintaining its structural and performance stability. Moreover, the surface has a relatively low coefficient of friction, which helps to reduce the heat generation during the cutting process and reduce the friction and wear between the cutting tool 12 and the workpiece, thereby increasing the service life of the cutting tool 12.

[0046] In the second step, when the device is first used, the high-speed rotating drill bit 17 will first enter the workpiece, and the cutting edge 14 will process the workpiece. The surface of the cutting edge 14 is coated with an alumina coating 15. The alumina coating 15 has a high melting point and good chemical stability, which can maintain structural stability at high temperatures and is not easily decomposed or oxidized. It has high hardness, which can effectively resist wear, and low thermal conductivity, which can reduce heat transfer and play a heat insulation role, thereby maintaining performance in high-temperature environments. It also has good anti-adhesive wear ability, reducing adhesion and wear with workpiece materials. In addition, the tool holder 18 is equipped with reinforcing ribs 19 to increase the rigidity of the internal structure of the tool holder 18. The rubber column 21 will greatly absorb the resonance generated during the operation of the device, thereby helping to increase the service life of the device.
