Description

Technical Field

[0001] This utility model relates to the field of hole reaming drill bit technology, specifically to an embedded metallurgical hole reaming drill bit. Background Technology

[0002] In the metallurgical industry, the treatment of the blast furnace taphole is a crucial step in ensuring smooth production. Specifically, the taphole needs to be opened each time iron is tapped to ensure the smooth flow of molten metal. Currently, this task is typically accomplished using reaming drills. To improve reaming efficiency and effectiveness, existing reaming drills have multiple cutting edges made of cemented carbide on their surface. These cutting edges are designed to increase the drill's cutting power and wear resistance, thereby more effectively reaming the taphole.

[0003] However, with prolonged use, these carbide cutting tools inevitably experience wear or breakage. On one hand, the harsh environment at the blast furnace taphole, with its extremely high temperatures and presence of various corrosive substances, accelerates the wear rate of the cutting tools. On the other hand, long-term, high-intensity use also causes the cutting tools to gradually lose their original sharpness, affecting the reaming effect. More importantly, in current market designs, the cutting tool is often fixedly connected to the drill bit body. Once the cutting tool is damaged, the entire drill bit needs to be replaced, which not only reduces the effective service life of the entire drill bit but also significantly increases its operating costs. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an embedded metallurgical drilling reamer bit to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An embedded metallurgical reaming drill bit includes a drill bit body, a plurality of embedding slots on the surface of the drill bit body, an alloy cutting head slidably installed inside the embedding slots, a transmission slot inside the drill bit body, a loading and unloading mechanism between the transmission slot and the embedding slots, a cutting edge on the surface of the drill bit body, and a chip removal groove on one side of the cutting edge.

[0007] Furthermore, in order to enable the free loading and unloading of the alloy cutting head on the drill bit body, the loading and unloading mechanism includes a transmission rod that is slidably installed inside the transmission groove, a limit rod that is fixedly connected to one side of the transmission rod, a shrinkage groove that is opened on one side of the transmission groove, the limit rod that is slidably installed in the shrinkage groove, a limit groove that is opened on one side of the surface of the alloy cutting head, and one end of the limit rod that cooperates with the limit groove.

[0008] Furthermore, in order to achieve a cooling effect during the reaming of the drill bit body, a water injection channel is opened at one end of the drill bit body, a water inlet is opened at one end of the transmission rod, a drain outlet is opened at the other end, and cooling holes are opened on the surface of the drill bit body, which are connected to the shrinkage groove.

[0009] Furthermore, in order to enable one end of the limiting rod to automatically slide out of the limiting groove when no force is applied, magnetic blocks are fixedly connected to one side of both the limiting rod and the shrinkage groove.

[0010] Furthermore, in order to achieve a fixed connection between the drill bit body and the transmission device during drilling, a connecting ring is fixedly connected to one end of the drill bit body, and a positioning hole is opened on the surface of the connecting ring.

[0011] Furthermore, in order to enable the drill bit body to squeeze the transmission rod after installation, an adjustment groove is opened at one end of the drill bit body, and a squeezing cap is slidably installed inside the adjustment groove.

[0012] Furthermore, in order to facilitate the removal of the alloy cutting tip from the mounting slot, the surface of the alloy cutting tip is provided with a loading and unloading groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The loading and unloading mechanism allows for free loading and unloading of the alloy cutting heads within the slot, enabling quick and easy replacement. When some alloy cutting heads are worn or damaged, the entire drill bit does not need to be replaced; only the damaged cutting head portion needs to be replaced for continued use, significantly shortening maintenance time and improving work efficiency. Since only the damaged alloy cutting head needs to be replaced instead of the entire drill bit body, this greatly reduces equipment maintenance and replacement costs and effectively extends the overall service life of the drill bit.

[0015] 2. Through the interconnection between the water injection channel, the transmission groove, and the drain outlet, when the drill bit body is undergoing hole reaming, cooling water is injected into the water injection channel, and the cooling water is discharged on the side of the alloy cutter head to quickly cool the drill bit body, effectively reducing the temperature of the drill bit body during processing, preventing damage to the drill bit body caused by high temperatures during drilling, and further improving the service life of the drill bit body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, an embedded metallurgical drill bit for reaming is provided.

[0026] Example 1:

[0027] like Figures 1-5As shown, an embedded metallurgical reaming drill bit according to an embodiment of the present invention includes a conical drill bit body 1 made of cemented carbide. The surface of the drill bit body 1 has a plurality of embedding slots 2, and an alloy cutting head 3 is slidably mounted inside each embedding slot 2. The drill bit body 1 has two pairs of transmission slots 4 inside, and a loading / unloading mechanism 5 is provided between the transmission slots 4 and the embedding slots 2 to allow for free loading and unloading of the alloy cutting head 3. The surface of the drill bit body 1 has a spiral cutting edge 6 for cutting and drilling when the drill bit body 1 rotates. A chip removal groove 7 is provided on one side of the cutting edge 6 to facilitate the removal of chips generated during drilling. The loading / unloading mechanism 5... The device includes a hollow metal transmission rod 501 that is slidably installed inside the transmission groove 4. A pair of limiting rods 502 are fixedly connected to one side of the transmission rod 501. A shrinkage groove 503 is opened on one side of the transmission groove 4 corresponding to the loading and unloading groove 17. The limiting rods 502 are slidably installed in the shrinkage groove 503. A limiting groove 504 is opened on one side of the surface of the alloy cutter head 3. One end of the limiting rod 502 cooperates with the limiting groove 504. When the alloy cutter head 3 is installed in the inlay groove 2, by pushing the transmission rod 501, the transmission rod 501 can drive one end of the limiting rod 502 to cooperate in the limiting groove 504, thereby stably limiting the installed alloy cutter head 3.

[0028] like Figures 1-5 As shown, a water injection channel 8 is opened at one end of the drill bit body 1, and one end of the water injection channel 8 is connected to each of the transmission grooves 4. A water inlet 9 is opened at one end of the transmission rod 501, and a drain outlet 10 is opened at the other end. Cooling holes 11 are opened on the surface of the drill bit body 1, and the cooling holes 11 are connected to the shrinkage groove 503. By injecting cooling water into the water injection channel 8, the cooling water can enter the shrinkage groove 503 through the hollow transmission rod 501 and be discharged through the drain outlet 10 when the drill bit body 1 is drilling. The surface of the drill bit body 1 is cooled. Magnetic blocks 12 are fixedly connected to one side of the limiting rod 502 and the shrinkage groove 503. The two magnetic blocks 12 are oriented in opposite directions and attract each other. When the transmission rod 501 is pushed and one end of the limiting rod 502 is installed in the limiting groove 504, the two magnetic blocks 12 are attracted to each other. When the transmission rod 501 is not pushed, the magnetic blocks 12 attract each other and can drive the limiting rod 502 to slide out of the limiting groove 504, realizing the automatic reset of the limiting rod 502; a connecting ring 13 is fixedly connected to one end of the drill bit body 1, and a positioning hole 14 is opened on the surface of the connecting ring 13 to facilitate the fixed installation of the drill bit body 1 on the transmission device during drilling; an adjustment groove 15 is opened at one end of the drill bit body 1, and a compression cover 16 is slidably installed inside the adjustment groove 15. When the drill bit body 1 is fixedly installed at the end of the transmission device through the connecting ring 13 and the positioning hole 14, the compression cover 16 can be compressed, thereby pushing the transmission rod 501 to move towards one end of the transmission groove 4; a loading and unloading groove 17 is opened on the surface of the alloy cutter head 3 to facilitate the removal of the alloy cutter head 3 from the inlay groove 2 when disassembling the alloy cutter head 3.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the alloy cutter head 3 is installed in the inlay groove 2. By pushing the extrusion cover 16, the extrusion cover 16 can push the transmission rod 501 to move upward in the transmission groove 4. After the transmission rod 501 moves, it drives one end of the limiting rod 502 to be installed in the limiting groove 504, thereby stably limiting the installed alloy cutter head 3. Conversely, the alloy cutter head 3 can be disassembled. When the drill body 1 is fixedly installed at one end of the drilling transmission device through the connecting ring 13 and the positioning hole 14, the extrusion cover 16 can be fixed on one side of the drill body 1. Therefore, after the drill body 1 is installed, each alloy cutter head 3 will be stably limited in the inlay groove 2, ensuring the stability of drilling.
