Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutters, in particular to a durable cutter made of superhard material. Background Art
[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. Most cutting tools are machine-made, but there are also hand-made ones. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "cutting tools" is generally understood as metal cutting tools. Cutting tools for cutting wood are called woodworking tools. There is also a special type of cutting tools used for geological exploration, well drilling, and mine drilling, called mining tools.
[0003] A cutting tool as disclosed in the publication number CN108472735B, the patent relates to a cutting tool, the cutting tool comprises a tool holder body (14; 14') having a shank (12; 12') and a head (13; 13'). The head has a blade seat (15; 15'), wherein a cutting blade (20; 20') is detachably mounted by a locking member (18; 18'). The seat comprises at least one bottom surface (16; 16'), and the cutting blade is placed on the at least one bottom surface. A coolant delivery member (29; 29') is formed integrally with the tool holder body. A normal line (N; N') of the at least one bottom surface (16; 16') intersects with the coolant delivery member, so that the coolant delivery member at least partially covers the cutting blade. When observed in a side view, the coolant delivery member (29; 29') is separated from the locking member (18; 18') and the cutting blade (20; 20'), but the cutting blade in the above patent is an ordinary tool. Ordinary tools may lack sufficient balance between hardness and toughness, resulting in the tool being easily worn, blunted or even broken during long-term or high-intensity cutting operations. At the same time, its coating technology may also be relatively simple and unable to effectively resist the high temperature, high pressure and corrosive environment generated during the cutting process, thereby accelerating the tool wear process; secondly, the durability of ordinary tools is relatively limited, and they are often unable to withstand long-term continuous operation or high-load cutting tasks, and need to be frequently replaced, which not only increases the downtime in the production process, reduces production efficiency, but also increases production costs.
[0004] Therefore, there is an urgent need for a durable cutting tool made of superhard material to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a durable cutting tool made of superhard material, which has the advantage of long service life and solves the problems raised by the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a durable cutting tool made of superhard material, comprising a cutting tool, wherein the cutting tool comprises a material component and a coating structure, wherein the material component comprises a silicon carbide material layer, nickel metal material layers are arranged on both sides of the silicon carbide material layer, cobalt metal material layers are arranged on the opposite sides of the two nickel metal material layers, and aluminum oxide material layers are arranged on the opposite sides of the two cobalt metal material layers.
[0007] The coating structure comprises a potassium coating located on one side of the aluminum oxide material layer, and nitrogen coatings are arranged on opposite sides of the two potassium coatings. The number of the coating structures is two.
[0008] A plurality of reinforcing components are embedded inside the material component.
[0009] Furthermore, as a preferred embodiment of the present invention, the reinforcing component includes an aluminum oxide ceramic material layer and a silicon nitride ceramic material layer, and the aluminum oxide ceramic material layer and the silicon nitride ceramic material layer are cross-arranged.
[0010] Furthermore, as a preferred embodiment of the present invention, a plurality of bumps are provided on one side of the potassium coating, and a placement groove adapted to the bumps is provided on one side of the nitrogen coating.
[0011] Furthermore, as a preferred embodiment of the present invention, a front surface of the tool is provided with through holes, and the number of the through holes is several.
[0012] Furthermore, as a preferred embodiment of the present invention, two mounting plates are fixedly connected to the top of the tool, and a fixing bolt is provided through one side of the mounting plate.
[0013] Beneficial effects. The technical solution of the present application has the following technical effects: the utility model has the advantage of long service life. In actual use, under the action of the material components, the structural strength of the tool is enhanced, so that the tool can maintain its shape and performance when subjected to a large cutting force, and effectively resist deformation or damage caused by external forces; and under the action of the alumina oxide material layer, the corrosion resistance of the tool is enhanced, so that the tool can maintain good cutting performance in a humid or corrosive environment. In addition, the alumina oxide material layer also indirectly promotes the long-term maintenance of the tool sharpness, because it reduces the edge passivation caused by corrosion, ensuring a smooth cutting process; secondly, under the action of the coating structure, it effectively isolates heat and reduces the temperature fluctuation of the tool substrate, thereby maintaining the stability of the physical properties of the tool material and avoiding adverse effects such as hardness loss and strength reduction caused by excessively high temperatures. Therefore, even under extremely high temperature conditions, the tool can maintain stable cutting performance, ensuring continuous improvement in processing quality and production efficiency.

[0021] As attached Figure 1 To Attachment Figure 3As shown: This embodiment provides a durable cutting tool made of superhard material, including a cutting tool 1. The cutting tool 1 includes a material component 11 and a coating structure 12. The material component 11 includes a silicon carbide material layer 111. Nickel metal material layers 112 are arranged on both sides of the silicon carbide material layer 111. Cobalt metal material layers 113 are arranged on the opposite sides of the two nickel metal material layers 112. Aluminum oxide material layers 114 are arranged on the opposite sides of the two cobalt metal material layers 113.
[0022] The coating structure 12 includes a potassium coating 121 located on one side of the aluminum oxide material layer 114 . A nitrogen coating 122 is disposed on the opposite sides of the two potassium coatings 121 . The number of coating structures 12 is two.
[0023] A plurality of reinforcing components 13 are embedded in the material component 11 .
[0024] Specifically, the reinforcing component 13 includes an aluminum oxide ceramic material layer 131 and a silicon nitride ceramic material layer 132 , and the aluminum oxide ceramic material layer 131 and the silicon nitride ceramic material layer 132 are cross-arranged.
[0025] In this embodiment: by setting the reinforcing component 13, the aluminum oxide ceramic material layer 131 and the silicon nitride ceramic material layer 132 have good thermal stability, which enhances the structural strength of the tool 1 and also helps the tool 1 maintain stable cutting performance in a high temperature environment and reduce performance degradation caused by temperature changes.
[0026] Specifically, a plurality of bumps 2 are disposed on one side of the potassium coating 121 , and a placement groove 3 adapted to the bumps 2 is opened on one side of the nitrogen coating 122 .
[0027] In this embodiment: by using the bump 2 and the placement groove 3 in combination, the contact area between the potassium coating 121 and the nitrogen coating 122 can be significantly increased, thereby enhancing the bonding force between the potassium coating 121 and the nitrogen coating 122. This locking method helps prevent the potassium coating 121 and the nitrogen coating 122 from peeling off or falling off during use, thereby improving the stability and durability of the potassium coating 121 and the nitrogen coating 122.
[0028] Specifically, the front surface of the tool 1 is provided with a plurality of through holes 4 .
[0029] In this embodiment, the provision of the through hole 4 not only reduces the material cost of the tool 1 , but also helps to reduce the vibration of the tool 1 during the cutting process and improve the cutting stability.
[0030] Specifically, two mounting plates 5 are fixedly connected to the top of the tool 1 , and a fixing bolt is provided through one side of the mounting plate 5 .
[0031] In this embodiment, the mounting plate 5 and the fixing bolts 6 are used in combination to provide a connection method between the tool 1 and other objects, thereby improving the stability of the tool 1.
[0032] The working principle and use process of the utility model are as follows: first, the silicon carbide material layer 111 has extremely high hardness and can effectively resist wear during the cutting process, so that the wear resistance of the tool 1 is improved; under the action of the nickel metal material layer 112 and the nickel metal material layer 112, the structural strength of the tool 1 is enhanced, so that the tool 1 can still maintain its shape and performance when subjected to a large cutting force, thereby improving the processing efficiency and precision; under the action of the aluminum oxide material layer 114, the corrosion resistance of the tool 1 is enhanced. When the tool 1 works in a humid or corrosive environment, this feature can protect the tool 1 from environmental damage and maintain its good cutting performance; the potassium coating 121 and the nitrogen coating 122 are protective coatings that can further reduce the friction and wear between the tool 1 and the workpiece, while preventing the surface of the tool 1 from being oxidized or corroded, thereby improving the overall performance and service life of the tool 1; finally, by embedding the reinforcing component 13 in the interior of the material component 11, the tool 1 is provided with enhanced structural strength, which helps the tool 1 to maintain stable cutting performance in a high temperature environment and reduce the performance degradation caused by temperature changes, thereby achieving the purpose of facilitating the extension of the service life of the tool 1.
