[0001] This utility model relates to the field of hobbing technology, specifically to a wedge-shaped toothed cutter ring structure. Background Technology

[0002] In engineering fields such as tunnel excavation and mining, cutting tools face extremely severe wear challenges. As a key tool component, the improved wear resistance of wedge-shaped toothed cutter rings is crucial for the efficient operation of the entire project. This is especially true when dealing with high-hardness, highly abrasive formations and sandstone interlayers, where tool wear is rapid, complex geological conditions lead to short service life, and severely impact project efficiency and cost. Therefore, a wedge-shaped toothed cutter ring structure is proposed. Utility Model Content

[0005] In some embodiments, the base of the blade is an alloy steel metal material.

[0006] In some embodiments, the wear-resistant layer is a composite material made of alloy steel metal material mixed with ceramic particles or carbide particles.

[0007] In some embodiments, an annular groove is formed on the blade body.

[0008] In some embodiments, each of the wedge-shaped alloy cutting teeth is provided with a strip groove, and each strip groove is filled with a wear-resistant layer material.

[0009] In some embodiments, a connecting groove is provided between the plurality of strip grooves.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This invention enhances the wear resistance of the blade ring layer and improves the service life of the blade by setting grooves between each wedge-shaped alloy cutting tooth and filling the grooves with wear-resistant material. At the same time, it connects the grooves with the wear-resistant layer, improves the integrity of the wear-resistant layer, strengthens the bonding strength between the wear-resistant layer and the blade, and prevents the blade from falling off during use.

[0016] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] See Figure 1-3A wedge-shaped toothed blade ring structure includes a blade body 1, a bearing 2 disposed in the middle of the blade body 1, a blade ring layer 3 disposed on the outer ring of the blade body 1, a wear-resistant layer disposed on the surface of the blade ring layer 3, and the blade ring layer 3 including a plurality of annular arrays of wedge-shaped alloy blades 31. Grooves 32 are disposed between the plurality of wedge-shaped alloy blades 31, and each groove 32 is filled with wear-resistant layer material, and the groove 32 is connected to the wear-resistant layer. This invention, by providing grooves 32 between each wedge-shaped alloy blade 31 and filling the grooves 32 with wear-resistant layer material, not only enhances the wear resistance of the blade ring layer 3 and improves the service life of the blade body 1, but also improves the integrity of the wear-resistant layer by connecting the grooves 32 to the wear-resistant layer, strengthens the bonding strength between the wear-resistant layer and the blade body 1, and prevents the blade body 1 from falling off during use.

[0020] In some embodiments, the base of the blade body 1 is an alloy steel metal material. The alloy steel metal matrix material, which has high strength and high toughness, is selected as the base of the blade body 1. It can be a chromium-nickel quenched and tempered steel, but is not limited to this, to improve the strength of the blade body 1.

[0021] In some embodiments, the wear-resistant layer is a composite material consisting of alloy steel metal material mixed with ceramic particles or carbide particles. The ceramic particles or carbide particles possess high hardness and high wear resistance, and can be tungsten carbide or titanium carbide, but are not limited to these.

[0022] In some embodiments, an annular groove 4 is formed on the blade body 1. The operator fills the annular groove 4 on the blade body 1 with wear-resistant material, which enables the wear-resistant layer to connect with the blade body 1. This not only enhances the connection strength between the wear-resistant layer and the blade body 1 and prevents the wear-resistant layer from falling off during use, but also improves the overall strength of the blade body 1.

[0023] In some embodiments, each of the wedge-shaped alloy cutting teeth 31 is provided with a strip-shaped groove 33, and each strip-shaped groove 33 is filled with a wear-resistant layer material. This can enhance the strength of the wedge-shaped alloy cutting teeth 31, improve the wear resistance of the wedge-shaped alloy cutting teeth 31, and allow the cutting body 1 to better withstand the cutting force and friction from the rock strata during use.

[0024] In some embodiments, a connecting groove 5 is provided between the plurality of strip grooves 33. An operator can spray wear-resistant material into the connecting groove 5, thereby connecting the wear-resistant materials in the plurality of strip grooves 33 together to form a whole, which not only enhances the overall strength of the blade ring layer 3, but also improves the integrity of the wedge alloy blade teeth 31 and enhances the bonding strength between the wear-resistant material and the blade body 1.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
