Description

Technical Field

[0001] This utility model relates to the field of milling cutters, specifically a high-efficiency, vibration-resistant tungsten carbide milling cutter. Background Technology

[0002] In the field of machining, tungsten carbide end mills are widely used due to their high hardness, wear resistance, and good cutting performance. However, during high-speed cutting, tungsten carbide end mills are often subjected to significant vibrations, which not only affect machining accuracy but may also accelerate tool wear and shorten their service life. Furthermore, tungsten carbide end mills generate a large amount of heat during use; if this heat is not dissipated in time, it will further affect the tool's performance and stability.

[0003] Traditional tungsten carbide end mill designs often focus on improving cutting performance, while neglecting vibration resistance and heat dissipation. For example, the method of fixing the end mill to the fixture may be relatively simple, lacking effective vibration damping measures; at the same time, the heat dissipation design of the end mill shank is often overlooked, leading to heat accumulation and affecting the tool's continuous operation capability. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency, vibration-resistant tungsten carbide end mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency vibration-resistant tungsten carbide end mill, comprising a tungsten carbide end mill body, a silicone sleeve fitted at the top of the tungsten carbide end mill body, a silicone strip integrally formed on the bottom surface of the silicone sleeve, the bottom end of the silicone strip integrally formed on the surface of the silicone ring, and the silicone ring fitted on the shaft of the tungsten carbide end mill body.

[0006] Preferably, the top surface of the tungsten carbide end mill body is provided with a reserved groove, the reserved groove is an annular groove, and a silicone sleeve is fitted and fixed in the reserved groove, the height of the silicone sleeve being greater than the height of the reserved groove.

[0007] Preferably, the top surface of the tungsten carbide end mill body is provided with an insert groove in the center, and a plug is inserted and fixed inside the insert groove. The plug is integrally formed on the bottom surface of the top plate of the silicone sleeve.

[0008] Preferably, the top surface of the silicone sleeve has a centrally formed protrusion, which is an arc-shaped protrusion.

[0009] Preferably, the bottom surface of the reserved slot is provided with a side groove. The tungsten carbide end mill body includes a rod and a cutter body integrally formed at the bottom end of the rod. The side groove penetrates the bottom surface of the rod. Multiple side grooves are provided, and the multiple side grooves are arranged at equal distances and of equal size with the rod of the tungsten carbide end mill body as the central axis.

[0010] Preferably, the silicone strip and the side groove correspond one-to-one, the silicone strip is inserted into the side groove, the thickness of the silicone strip is greater than the depth of the side groove, and a notch is opened on the side of the silicone strip that protrudes from the outside of the side groove, the height of the notch is equal to the height of the silicone strip.

[0011] Preferably, the surface of the notched groove is provided with through holes, and there are multiple through holes, which are arranged vertically with equal spacing and size.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention proposes a high-efficiency, vibration-resistant tungsten carbide end mill. A silicone sleeve with a protrusion is fitted onto the top of the end mill body. When the end mill is inserted into a fixture, the silicone sleeve and protrusion effectively clamp the end mill between the end mill and the fixture, providing excellent vibration damping. This design significantly reduces vibration during cutting, improving machining accuracy and tool life. A groove is cut into the shank of the tungsten carbide end mill body, and a silicone strip is installed. The notches and through-holes on the surface of the silicone strip increase the heat dissipation area, promoting heat dissipation. Furthermore, the protruding design of the silicone strip from the groove allows workers to easily grasp the silicone strip when disassembling the end mill, preventing burns to their fingers.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-7 This utility model provides a technical solution: a high-efficiency, vibration-resistant tungsten carbide end mill, comprising a tungsten carbide end mill body 1, a silicone sleeve 4 fitted onto the top end of the tungsten carbide end mill body 1, and a pre-reserved groove 2 formed on the top surface of the tungsten carbide end mill body 1. The pre-reserved groove 2 is an annular groove, and the silicone sleeve 4 is fitted and fixed in the pre-reserved groove 2. The height of the silicone sleeve 4 is greater than the height of the pre-reserved groove 2. After the silicone sleeve 4 is fitted and fixed onto the top end of the tungsten carbide end mill body 1, when the top end of the tungsten carbide end mill body 1 is inserted into a tool holder, and when the holder is locked, the silicone sleeve 4 is clamped onto the tungsten carbide end mill body. Between the body 1 and the fixture, the silicone sleeve 4 provides a vibration damping structure between the fixture and the tungsten carbide end mill body 1; the top surface of the tungsten carbide end mill body 1 has a centrally located insert groove 3, and a plug 5 is inserted and fixed inside the insert groove 3. The plug 5 is integrally formed on the bottom surface of the top plate of the silicone sleeve 4; the top surface of the silicone sleeve 4 has an integrally formed protrusion 6, which is an arc-shaped protrusion; when the top of the tungsten carbide end mill body 1 is inserted into the fixture, the protrusion 6 presses tightly against the surface of the fixture, thus achieving vibration damping between the fixture and the tungsten carbide end mill body 1 at the top of the tungsten carbide end mill body 1.

[0025] The bottom surface of the silicone sleeve 4 is integrally formed with a silicone strip 8. The bottom end of the silicone strip 8 is integrally formed on the surface of the silicone ring 9. The silicone ring 9 is fitted onto the rod of the tungsten carbide end mill body 1. The bottom surface of the pre-reserved groove 2 is provided with a side groove 7. The tungsten carbide end mill body 1 includes a rod and a cutter body integrally formed at the bottom end of the rod. The side groove 7 penetrates the bottom surface of the rod. There are multiple side grooves 7, which are arranged at equal distances and of equal size with the rod of the tungsten carbide end mill body 1 as the central axis. The silicone strip 8 and the side groove 7 correspond one-to-one. The silicone strip 8 is inserted into the side groove 7. The thickness of the silicone strip 8 is greater than the depth of the side groove 7. The side of the silicone strip 8 that protrudes from the outside of the side groove 7 is provided with a notch 10. The height of the notch 10 is equal to the height of the silicone strip 8. The surface of the notch 10 is provided with a through hole 11. There are multiple through holes 11, which are arranged vertically at equal distances and of equal size.

[0026] The reason for opening the side groove 7 on the shank of the tungsten carbide end mill body 1 is to increase the heat dissipation area of ​​the shank. When the silicone strip 8 is installed inside the side groove 7, the notch 10 and through hole 11 on the surface of the silicone strip 8 facilitate the dissipation of the heat absorbed by the silicone strip 8. Furthermore, the silicone strip 8 protrudes from the side groove 7. When the tungsten carbide end mill body 1 is removed from the fixture after use, the fingers can be pinched on the silicone strip 8 on both sides of the tungsten carbide end mill body 1 to prevent the tungsten carbide end mill body 1 from burning the hands of the workers after use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
