Description

Technical Field

[0001] This utility model relates to the field of auger drill technology, and in particular to an alloy auger drill bit. Background Technology

[0002] As is well known, a swivel drill is a type of drill bit, mainly used for drilling holes in wood. Drilling generates a large amount of debris. Although our company has an improved tungsten carbide swivel drill bit disclosed in Chinese Utility Model Patent No. CN221809426U, which describes an integrally formed drill rod and shank, with a helical cutting edge along the length of the drill rod and a cutter head welded to the top of the helical cutting edge, and a center drill bit integrally formed with the drill rod, although the cutter head is made of alloy material, inaccurate installation of the cutter head on the top of the helical cutting edge leads to deviations during subsequent welding. This results in deviations on both sides of the top face of the helical cutting edge, hindering rapid manufacturing and the production of products that meet requirements. Utility Model Content

[0043] 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 the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0044] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9, Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 An alloy-supported drill bit includes a drill shank 1 and a drill rod 2 mounted on the drill shank 1. A spiral cutting blade 3 is mounted on the drill rod 2, a positioning drill 4 is mounted on the spiral cutting blade 3, and a deep-cutting cutting blade 5 is mounted on the spiral cutting blade 3. The deep-cutting cutting blade 5 and the spiral cutting blade 3 are quickly positioned and connected via a positioning structure, which helps to avoid deviations in the installation of the deep-cutting cutting blade 5 on the spiral cutting blade 3. This prevents the final product from failing to meet requirements during subsequent processing and manufacturing. Furthermore, the deep-cutting cutting blade 5 and the spiral cutting blade 3 are welded together, greatly improving the structural robustness. The deep-cutting cutting blade 5 is made of alloy material, which has better wear resistance and can significantly extend its service life.

[0045] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the spiral cutting tool 3 includes spiral cutting edges 31 evenly spaced on the drill rod 2, with spiral cutting grooves 32 provided between adjacent spiral cutting edges 31. This arrangement not only facilitates drilling deep holes but also improves chip removal. The spiral cutting edges 31 and the drill rod 2 are integrally formed, greatly improving the structural robustness. In this embodiment, the spiral cutting edges 31 are three-edged, which is not only reasonably arranged and simple in structure, but also easy to manufacture, and also facilitates better cutting and drilling.

[0046] like Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the spiral cutting edge 31 has evenly spaced serrations 311, which helps to improve the efficiency of cutting and drilling, and also helps to improve the heat dissipation effect.

[0047] Example 3: This can be explained based on Example 2, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the anti-drilling cutter 5 includes an anti-drilling cutting edge disposed on the upper end face of the helical cutting edge 31. The anti-drilling cutting edge includes a cutting body 51 disposed on the upper end face of the helical cutting edge 31. An inclined cutting edge 52 is disposed on one side of the cutting body 51. The cutting body 51 and the inclined cutting edge 52 are integrally formed, resulting in a robust structure with enhanced strength and significantly improved service life. Furthermore, the two sides of the cutting body 51 are concave arc-shaped, which facilitates better cutting and chip removal. Through the above-described technical solution of the anti-drilling cutter 5, the anti-drilling cutter 5 is designed to cut wood fibers, making the side of the hole smoother and the cutting edge sharper, thereby improving drilling efficiency.

[0048] Example 4: This can be explained based on Example 3, such as... Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the positioning structure includes a protrusion arranged on the upper end face of the spiral cutting edge 31 or the side of the positioning drill 4, and a groove arranged on the lower end face or side of the deep cutting edge. The groove and the protrusion cooperate to realize the quick positioning and installation of the deep cutting tool 5 on the upper end face of the spiral cutting edge 31. This is more conducive to the prevention of deviations in the installation of the deep cutting tool and the production of products that do not meet the requirements due to inaccurate welding in the subsequent process, and is more conducive to meeting production requirements.

[0049] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17and Figure 18 As shown, the positioning drill 4 uses a triangular pyramid or a cone with external threads. This type of setting is diverse and offers a wide range of choices, which is more conducive to meeting the user's needs.

[0050] Example 6: This can be described based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the drill shank 1 can be hexagonal prism or cylindrical, offering a variety of types and a wide range of choices. Further, the hexagonal prism-shaped drill shank 1 has at least one positioning groove 11, while in this embodiment, one or two positioning grooves 11 are used, which facilitates connection to external equipment. The cylindrical drill shank 1 has paired strip-shaped grooves 12 and ball-shaped grooves 13, a design that further facilitates connection to external components to meet different requirements.

[0051] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0052] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
