Description

Technical Field

[0001] This application belongs to the technical field of milling cutters, and particularly relates to a V-shaped milling cutter. Background Art

[0002] The original design intention of the V-shaped milling cutter is to meet specific processing requirements, especially in the processing of workpieces that need to form V-shaped grooves or similar shapes. With the continuous development of the manufacturing industry, the requirements for processing accuracy, efficiency, and surface quality are increasing day by day. As an efficient and precise processing tool, the V-shaped milling cutter has gradually gained favor in the market. The V-shaped milling cutter is usually made of cemented carbide or other high-performance materials, with excellent wear resistance and cutting performance. Its cutter body is V-shaped, and the cutting edges are precisely designed according to processing requirements to ensure processing accuracy and surface quality. However, some existing V-shaped cutters still have problems such as unreasonable structural design and easy damage to the cutter head after long-term use. Utility Model Content

[0003] The purpose of this application is to provide a V-shaped milling cutter that can solve the above problems.

[0004] The purpose of this application is to provide a V-shaped milling cutter, including:

[0005] A shank part, which is a cylinder;

[0006] A cutter body part;

[0007] A blade part, which is arranged on the cutter body part and includes a first blade and a second blade. The first blade and the second blade form a V-shaped cutting edge;

[0008] Wherein, the cutter body part and the blade part are made of alloy materials, and the first blade and the second blade are centrosymmetric about the axis of the cutter body part.

[0009] Using the above V-shaped milling cutter, both the cutter body part and the blade part are made of alloy materials, with excellent hardness, wear resistance, and corrosion resistance. They can maintain the sharpness and integrity of the cutting edge during long-term and high-intensity cutting processes, thereby effectively extending the service life of the tool, reducing the replacement frequency, and lowering the production cost. The centrosymmetric design of the first blade and the second blade about the axis of the cutter body part not only ensures the accuracy and consistency of the V-shaped cutting edge but also makes the cutting force more evenly distributed on the blade, reducing the stress concentration phenomenon and the risk of blade damage due to uneven force. At the same time, the centrosymmetric design also helps to improve the balance of the tool, reduce vibration during the cutting process, and improve processing accuracy and surface quality. At the same time, the design of the V-shaped cutting edge enables the tool to accurately and quickly machine V-shaped grooves or other similar shapes to meet high-precision processing requirements.

[0010] Further, the cutter body part includes:

[0011] Arc segment;

[0012] Straight segment;

[0013] Among them, the straight segment is connected to the tool shank part, one end of the arc segment is connected to the straight segment, and the other end extends along the axis from the outside to the inside in a curved shape towards the top of the tool body part and makes a smooth transition.

[0014] The arc segment is located at the top of the tool body part. One end of it is smoothly connected to the straight segment, and the other end extends along the axis from the outside to the inside in a curved shape until the top of the tool body part, and a smooth transition is achieved here. The curve design helps to disperse the impact force generated during cutting, reduce stress concentration, and thus improve the durability of the tool. The straight segment is directly connected to the tool shank part, which is used to transmit the cutting force and torque, ensuring that the blade can cut the workpiece stably and efficiently. It also provides an installation platform for the blade, enabling the blade to be firmly fixed on the tool body part and preventing loosening or falling off during cutting.

[0015] Furthermore: A fillet is provided between the straight segment and the tool shank part.

[0016] The design of the fillet can effectively disperse the stress concentration that may occur at the connection between the straight segment and the tool shank part. During the cutting process, the tool will be subjected to the cutting force and reaction force from the workpiece, and these forces may cause stress concentration at the connection, leading to tool damage. The fillet can smoothly transition these two parts, reduce the phenomenon of stress concentration, and thus improve the durability of the tool. It can also increase the strength of the connection to a certain extent. By optimizing the size and shape of the fillet, the connection can be made more solid, resisting various impacts and vibrations generated during cutting and maintaining the overall stability of the tool.

[0017] Furthermore, the angle of the V-shaped cutting edge formed by the first blade and the second blade is 90°V, and there is a gap between the two blades.

[0018] The V-shaped angle of the V-shaped cutting edge is 90°, that is, the included angle between the two blades is 90°. This means that the first blade and the second blade form a right angle at the intersection. When it is necessary to machine a right-angled or nearly right-angled V-shaped groove, the 90° V-shaped angle can ensure that the shape of the machined groove is accurate and consistent, meeting the requirements of high-precision machining. During the cutting process, the chips need to be effectively discharged to avoid accumulation at the cutting edge, which will affect the cutting effect and tool life. The gap provides a smooth discharge channel for the chips, helping to reduce the cutting resistance and cutting heat, and improving the cutting efficiency. The gap can also reduce the direct contact and friction between the two blades during cutting, thereby reducing wear and heat generation. This is very beneficial for maintaining the sharpness of the tool and extending its service life. In addition, in some cases, by adjusting the size of the gap between the blades, fine-tuning of the cutting force, cutting depth, and machining accuracy can be achieved.

[0019] Furthermore, a discharge groove is provided on the tool body portion. The discharge groove is located on one side of the blade, and there are two discharge grooves.

[0020] The discharge groove is located on one side of the blade. Its main function is to collect and discharge the chips generated during the cutting process. By timely removing the chips from the cutting area, it is possible to avoid chip accumulation on the blade, thereby reducing the cutting resistance and cutting heat, and preventing overheating and accelerated wear of the tool.

[0021] The beneficial effects of this application are as follows:

[0022] 1. Both the tool body portion and the blade portion are made of alloy materials, having excellent hardness, wear resistance, and corrosion resistance. They can maintain the sharpness and integrity of the cutting edge during long-term and high-intensity cutting processes, thereby effectively extending the service life of the tool, reducing the replacement frequency, and lowering the production cost;

[0023] 2. The first blade and the second blade are symmetrically designed about the axis center of the tool body portion. This not only ensures the accuracy and consistency of the V-shaped cutting edge but also makes the cutting force more evenly distributed on the blade, reducing the stress concentration phenomenon and lowering the risk of blade damage due to uneven force;

[0024] 3. The design of the V-shaped cutting edge enables the tool to accurately and quickly machine V-shaped grooves or other similar shapes, meeting the requirements of high-precision machining. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will combine the accompanying drawings to elaborate in detail on the V-shaped milling cutter provided by the embodiments of this application through specific embodiments and their application scenarios.

[0033] Embodiment 1:

[0034] As Figures 1 to 4 shown, the embodiment of this application provides a V-shaped milling cutter, including:

[0035] A shank portion 100, which is a cylinder;

[0036] A cutter body portion 200;

[0037] A blade portion 300, which is arranged on the cutter body portion 200 and includes a first blade 310 and a second blade 320, and the first blade 310 and the second blade 320 form a V-shaped cutting edge;

[0038] Among them, the cutter body portion 200 and the blade portion 300 are made of alloy materials, and the first blade 310 and the second blade 320 are centrosymmetric about the axis of the cutter body portion 200.

[0039] In some implementation manners of the embodiment of this application, as Figure 1 shown, using the above-mentioned V-shaped milling cutter, both the cutter body portion 200 and the blade portion 300 are made of alloy materials, having excellent hardness, wear resistance and corrosion resistance, and can maintain the sharpness and integrity of the cutting edge during long-term and high-intensity cutting processes, thereby effectively extending the service life of the tool, reducing the replacement frequency, and lowering the production cost. The centrosymmetric design of the first blade 310 and the second blade 320 about the axis of the cutter body portion 200 not only ensures the accuracy and consistency of the V-shaped cutting edge, but also makes the cutting force more evenly distributed on the blade, reduces the stress concentration phenomenon, and reduces the risk of blade damage due to uneven force. At the same time, the centrosymmetric design also helps to improve the balance of the tool, reduce vibration during the cutting process, and improve the machining accuracy and surface quality. At the same time, the design of the V-shaped cutting edge enables the tool to accurately and quickly machine V-shaped grooves or other similar shapes to meet the requirements of high-precision machining.

[0040] Example 2:

[0041] The embodiment of the present application provides a V-shaped milling cutter. In addition to including the above technical features, the V-shaped milling cutter of the embodiment of the present application further includes the following technical features.

[0042] As Figures 1 to 4 shown, the tool body part 200 includes:

[0043] Arc segment 210;

[0044] Straight segment 220;

[0045] Among them, the straight segment 220 is connected to the tool shank part 100. One end of the arc segment 210 is connected to the straight segment 220, and the other end extends along the axis from the outside to the inside in a curve shape towards the top of the tool body part 200 and makes a smooth transition.

[0046] In the embodiment of the present application, the arc segment 210 is located at the top of the tool body part 200. One end of it is smoothly connected to the straight segment 220, and the other end extends along the axis from the outside to the inside in a curve shape until the top of the tool body part 200, and a smooth transition is achieved here. The curve design helps to disperse the impact force generated during the cutting process, reduce stress concentration, and thus improve the durability of the tool. The straight segment 220 is directly connected to the tool shank part 100, which is used to transmit the cutting force and torque, ensuring that the cutting blade can cut the workpiece stably and efficiently. It also provides an installation platform for the cutting blade, enabling the cutting blade to be firmly fixed on the tool body part 200, avoiding loosening or falling off during the cutting process.

[0047] Moreover, a fillet 400 is provided between the straight segment 220 and the tool shank part 100.

[0048] In some embodiments of the present application, the design of the fillet 400 can effectively disperse the stress concentration that may occur at the connection between the straight segment 220 and the tool shank part 100. During the cutting process, the tool will be subjected to the cutting force and reaction force from the workpiece, and these forces may cause stress concentration at the connection, resulting in tool damage. The fillet 400 can smoothly transition these two parts, reduce the phenomenon of stress concentration, and thus improve the durability of the tool. It can also increase the strength of the connection to a certain extent. By optimizing the size and shape of the fillet 400, the connection can be made more solid, resisting various impacts and vibrations generated during the cutting process and maintaining the overall stability of the tool.

[0049] Example 3:

[0050] The embodiment of the present application provides a V-shaped milling cutter. In addition to including the above technical features, the V-shaped milling cutter of the embodiment of the present application further includes the following technical features.

[0051] As Figure 4As shown, the angle of the V-shaped cutting edge formed by the first blade 310 and the second blade 320 is 90°V, and there is a gap between the two blades.

[0052] In the embodiment of the present application, the V-shaped angle of the V-shaped cutting edge is 90°, that is, the included angle between the two blades is 90°. This means that the first blade 310 and the second blade 320 form a right angle at the intersection. When a V-shaped groove with a right angle or close to a right angle needs to be machined, the 90° V-shaped angle can ensure that the shape of the machined groove opening is accurate and consistent, meeting the requirements of high-precision machining. During the cutting process, chips need to be effectively discharged to avoid accumulation at the cutting edge, which affects the cutting effect and tool life. The gap provides a smooth discharge channel for the chips, helping to reduce cutting resistance and cutting heat, and improving cutting efficiency. The gap can also reduce the direct contact and friction between the two blades during the cutting process, thereby reducing wear and heat generation. This is very beneficial for maintaining the sharpness of the tool and extending its service life. In addition, in some cases, by adjusting the size of the gap between the blades, fine adjustment of the cutting force, cutting depth, and machining accuracy can be achieved.

[0056] In the embodiment of the present application, the chip discharge groove 500 is located on one side of the blade, and its main function is to collect and discharge the chips generated during the cutting process. By timely removing the chips from the cutting area, chip accumulation on the blade can be avoided, thereby reducing cutting resistance and cutting heat, and preventing overheating and increased wear of the tool.
