[0002] Fused bricks have extremely high refractory temperatures and can withstand physical and chemical changes and mechanical effects in high temperature environments for a long time. Special-shaped fused bricks usually refer to fused bricks with non-standard shapes or specific geometric forms. In the construction of glass kilns, various special-shaped fused bricks are an indispensable part of each glass kiln.

[0003] Some special-shaped fused bricks have special-shaped brick holes, such as conical holes. In the prior art, such fused bricks with conical holes are directly cast and then the inside of the conical holes are cleaned by manual electric tools. The disadvantages of this method include: 1) There will be more surface cracks inside the conical holes, and the cracks may even directly cause the fused bricks to break; 2) Manual cleaning of the inner surface of the conical holes can only be used to simply clean the dust and impurities on the inner surface of the conical holes.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] like Figures 1 to 3 As shown, the present invention provides a diamond drill bit, comprising a drill bit body 2;

[0035] The cross-sectional area of ​​the drill body 2 gradually decreases from the proximal end to the distal end. The drill body 2 includes a plurality of long teeth 3 and a plurality of short teeth 4. The plurality of long teeth 3 and the plurality of short teeth 4 are alternately distributed along the circumference of the drill body 2. The outer side surfaces of the plurality of long teeth 3 and the plurality of short teeth 4 match each other. Generally speaking, the drill body 2 as a whole has a central axis. The outer side surfaces of the plurality of long teeth 3 and the plurality of short teeth 4 need to match each other. For example, the drill body 2 can be rotated circumferentially along the central axis, and the circumferential outer grinding surfaces formed by the plurality of long teeth 3 can basically overlap, and the plurality of short teeth 4 can be rotated circumferentially. The circumferential outer grinding surfaces formed by each of the teeth may substantially overlap, and the circumferential outer grinding surfaces formed by the plurality of short teeth 4 may also be substantially included in the circumferential outer grinding surfaces formed by the plurality of long teeth 3; the extension direction of the plurality of long teeth 3 matches the axial direction of the drill body 2, and the extension direction of the plurality of short teeth 4 matches the axial direction of the drill body 2. For example, each long tooth 3 and / or each short tooth 4 may substantially extend in a straight line, and the extension direction of each long tooth 3 and / or each short tooth 4 may intersect with the axis of the drill body 2, and may also substantially intersect at the same point;

[0036] The long teeth 3 and short teeth 4 are arranged alternately in the circumferential direction, which can evenly disperse the pressure and wear during the drilling process, thereby extending the service life of the drill bit and improving the drilling speed and accuracy; the long teeth 3 and short teeth 4 are arranged alternately in the circumferential direction, which can also produce a stronger cutting action and improve the surface finish of the tapered hole obtained by processing. The long teeth can produce initial cutting and provide deeper cutting force, while the short teeth help to break the material and remove debris, and refine the surface. This combination can improve the material removal efficiency; in addition, the long teeth 3 and short teeth 4 are arranged alternately in the circumferential direction, which can also help reduce vibration during cutting or grinding, which can not only improve the stability of grinding, but also reduce the risk of damage to the workpiece to be processed or the diamond drill bit itself.

[0037] The plurality of long teeth 3 and the plurality of short teeth 4 each include a grinding portion located on an outer side thereof, and the outer sides of the grinding portions of the plurality of long teeth 3 and the grinding portions of the plurality of short teeth 4 are coated with a diamond coating;

[0038] The plurality of long teeth 3 and the plurality of short teeth 4 are alternately distributed along the circumference of the drill body 2, and the plurality of long teeth 3 and the plurality of short teeth 4 include a grinding portion located on the outer side thereof, so that the drill bit not only has a cutting function, but also can perform a grinding operation. When the diamond drill bit is used to process a tapered hole in an electric fused brick, the inner surface of the processed tapered hole can be ensured to be smooth and clean without cracks and other surface defects;

[0039] The grinding parts of the multiple long teeth 3 and the grinding parts of the multiple short teeth 4 are coated with diamond coatings on the outside, which can not only improve the wear resistance of the diamond drill bit and the service life of the diamond drill bit, but also, if the diamond coating is worn during use, the diamond coating can be re-plated on the grinding parts of the long teeth 3 and the grinding parts of the short teeth 4 by means of re-plating.

[0040] like Figure 1 As shown, in some embodiments of the present invention, the diamond drill bit further comprises a connecting portion 1, and the drill body 2 can be fixedly connected to the end of the connecting portion 1, more specifically, the connecting portion 1 can be connected to the proximal end of the drill body 2. The existence of the connecting portion 1 allows the diamond drill bit to be mounted on a corresponding grinding mechanism.

[0041] like Figure 1As shown, in some embodiments of the present invention, the plurality of long teeth 3 and the plurality of short teeth 4 can be connected to the drill bit body 2 by welding, the plurality of long teeth 3 can also be connected to the drill bit body 2 to form an integrated structure, and the plurality of short teeth 4 can also be connected to the drill bit body 2 to form an integrated structure. The above-mentioned integrated structure generally refers to that the long teeth 3 and / or the short teeth 4 are integrated with the drill bit body 2, and there is no obvious other connection method (for example, welding, etc.) between them. A plurality of long teeth 3 and a plurality of short teeth 4 can be evenly distributed along the circumference of the drill bit body 2, and this arrangement has the following advantages: first, this design can disperse the wear of the diamond drill bit during the drilling process, thereby extending the service life of the diamond drill bit; second, this design helps to dissipate the heat generated during the drilling process more quickly, thereby preventing damage to the drill bit or performance degradation caused by overheating; third, this design helps the diamond drill bit to maintain a stable cutting force during the drilling process, thereby avoiding the adverse effects of fluctuations in the cutting force on the drilling quality; fourth, by adopting the arrangement in which the long teeth and the short teeth are evenly distributed along the circumference of the drill bit body 2, a certain space is formed between adjacent long teeth 3 and short teeth 4, so that during the drilling process, the debris generated during the drilling can be stored and discharged through the space, thereby preventing the debris from affecting the drilling accuracy of the long teeth 3 and short teeth 4 on the diamond drill bit, while also reducing the drilling resistance and drilling energy consumption, thereby improving the drilling efficiency. The number of the long teeth 3 and the number of the short teeth 4 can be the same. Specifically, the number of the long teeth 3 and the number of the short teeth 4 can both be selected from 5 to 10.

[0042] like Figure 1 As shown, in some embodiments of the present invention, the drill body 2 is a cone-shaped structure, more specifically, the drill body 2 can be a truncated cone-shaped structure, and the axial length of the drill body 2 can be approximately 160 to 300 mm; the outer diameter of the distal end of the drill body 2 is 40 to 120 mm, and the outer diameter of the proximal end of the drill body 2 is 65 to 400 mm; when the diamond drill bit is processed and manufactured, the specifications of the drill body 2 can be designed according to the size of the tapered hole to be processed.

[0043] like Figure 1 As shown, in some embodiments of the present invention, the ratio of the axial length of the drill body 2 to the axial length of the portion thereof including the plurality of short teeth 4 may be (1.50-2.50):1, or may be approximately 1:(1.60-2.30), or may be approximately 1:(1.80-2.10), or may be approximately 1:(1.90-2.10); when the diamond drill bit is processed and manufactured, the ratio is reasonably set according to the size of the tapered hole to be processed;

[0044] like Figure 1 and Figure 3As shown, in some embodiments of the present invention, a plurality of long teeth 3 may extend from the proximal end of the drill body 2 to the distal end of the drill body 2, the plurality of long teeth 3 may extend substantially in a straight line, the lengths of the plurality of long teeth 3 may be substantially the same, and the angle between the outer side surface of the long teeth 3 and the axial direction of the drill body 2 may be approximately 5 to 45°;

[0045] The plurality of short teeth 4 may extend from the proximal end of the drill body 2 to the distal end of the drill body 2, the plurality of short teeth 4 may extend substantially in a straight line, the lengths of the plurality of short teeth 4 may be substantially the same, and the angle between the outer side surface of the short teeth 4 and the axial direction of the drill body 2 may be approximately 5 to 45°; similarly, when the diamond drill bit is processed and manufactured, the specifications of the long teeth 3 and the short teeth 4 may be designed according to the size of the tapered hole to be processed;

[0046] The multiple long teeth 3 and the multiple short teeth 4 can all extend basically in a straight line, and the lengths of the multiple long teeth 3 can be basically the same, and the lengths of the multiple short teeth 4 can be basically the same, thereby ensuring uniform distribution of cutting force and stability of the diamond drill bit, and further ensuring that the aperture size of the drilled hole is more precise and the hole wall is smoother, that is, the accuracy and surface finish of the drilled hole can be guaranteed to meet the use requirements of special glass kilns.

[0047] like Figures 1 to 3 As shown, in some embodiments of the present invention, the length ratio of the short teeth 4 to the long teeth 3 may be approximately 1:1.50-2.50, or approximately 1:1.70-2.30, or approximately 1:1.90-2.10. More specifically, the length ratio of the short teeth 4 to the long teeth 3 may be approximately 1:2. The lengths of the short teeth 4 and the long teeth 3 generally refer to their dimensions in the extending direction from the proximal end to the distal end. When comparing the length ratios of the short teeth 4 and the long teeth 3, they are generally described by the overall lengths of the short teeth 4 and the long teeth 3 (for example, the average length of a plurality of short teeth 4, and the average length of a plurality of long teeth 3).

[0048] In the process of using the diamond drill bit to drill conical holes on the fused brick, since the multiple long teeth 3 can extend from the proximal end of the drill bit body 2 to the distal end of the drill bit body 2, and the multiple short teeth 4 can extend from the proximal end of the drill bit body 2 to the distal end of the drill bit body 2, in the early stage of drilling, the long teeth 3 are in direct contact with the fused brick, and the short teeth 4 are not in direct contact with the fused brick. In the later stage of drilling, both the long teeth 3 and the short teeth 4 are in direct contact with the fused brick. Since the cross-sectional area of ​​the drill bit body 2 gradually decreases from the proximal end to the distal end, the density of the grinding bits (i.e., the multiple long teeth 3) on the drill bit body 2 in the early stage of drilling and the density of the grinding bits (i.e., the long teeth 3 and the short teeth 4) on the drill bit body 2 in the later stage of drilling can be basically consistent, thereby ensuring the consistency of the core of the drilled hole at different stages of drilling, and further ensuring that the core of the drilled hole has higher precision and better surface finish.

[0049] The proximal and distal ends of a single short tooth 4 (corresponding to the proximal and distal ends of the drill body 2) may have substantially the same width, and the proximal and distal ends of a single long tooth 3 (corresponding to the proximal and distal ends of the drill body 2) may have substantially the same width. Further, a single short tooth 4 may have substantially the same width from its proximal end to its distal end (i.e., the width of each position of a single short tooth 4 in its extension direction may be substantially the same), and a single long tooth 3 may have substantially the same width from its proximal end to its distal end (i.e., the width of each position of a single long tooth 3 in its extension direction may be substantially the same). The width of a short tooth 4 and a long tooth 3 at a specific position generally refers to the size of the line segment corresponding to the outer side surface of the tooth on the cross section perpendicular to the axis of the drill body 2 at that position. Multiple long teeth 3 may also have substantially the same width, and multiple short teeth 4 may also have substantially the same width. When describing the width of a single short tooth 4, it may be described in terms of the overall width of the single short tooth 4 (for example, it may be the average width of the single short tooth 4 in its extension direction). When describing the width of a single long tooth 3, it may be described as the overall width of the single long tooth 3 (for example, it may be the average width of the single long tooth 3 in its extension direction);

[0050] Since the plurality of long teeth 3 may have substantially the same width, and the plurality of short teeth 4 may have substantially the same width, the diamond drill bit may maintain better cutting performance and stability, thereby making the diamond drill bit suitable for different cutting scenarios.

[0051] The ratio of the width of the multiple short teeth 4 to the width of the multiple long teeth 3 may be approximately 1:0.90-1.10, or approximately 1:0.95-1.05. More specifically, the ratio of the width of the short teeth 4 to the width of the long teeth 3 may be approximately 1:1. When comparing the width ratios of the short teeth 4 and the long teeth 3, they are usually described by the overall width of the multiple short teeth 4 and / or the multiple long teeth 3 (for example, it may be the average width of the multiple short teeth 4, or the average width of the multiple long teeth 3);

[0052] Since the ratio of the width of the short teeth 4 to the width of the long teeth 3 can be approximately 1:1, that is, the width of the short teeth 4 can be substantially the same as the width of the long teeth 3, this design has the following two advantages: first, it ensures that the density of the grinding bits (i.e., the plurality of long teeth 3) on the drill bit body 2 in the early stage of drilling is substantially consistent with the density of the grinding bits (i.e., the long teeth 3 and the short teeth 4) on the drill bit body 2 in the later stage of drilling, thereby ensuring the consistency of the hole cores drilled in the early stage of drilling and in the later stage of drilling, that is, ensuring the smoothness of the hole cores of the drilled tapered holes; second, it ensures that when manufacturing the diamond drill bit, it is conducive to the layout of the long teeth 3 and the short teeth 4, thereby facilitating the mass production of the diamond drill bit, and since the diamond drill bit can be processed and manufactured according to the specifications of different tapered holes, therefore, setting the ratio of the width of the short teeth 4 to the width of the long teeth 3 to 1:1 can facilitate the processing and manufacturing of diamond drill bits of various specifications;

[0053] Specifically, the width of the plurality of long teeth 3 may be approximately 3 to 15 mm, and the width of the plurality of short teeth 4 may be approximately 3 to 15 mm.

[0054] like Figures 1 to 3 As shown, in some embodiments of the present invention, the drill body 2 may include a central axis portion 5, which may be used to carry the above-mentioned multiple long teeth 3 and multiple short teeth 4, and may rotate circumferentially, thereby driving the multiple long teeth 3 and multiple short teeth 4 to rotate circumferentially to form a circumferential outer grinding surface. The axis of the central axis portion 5 may be substantially consistent with the axis of the drill body 2, for example, the drill body 2 may be coaxial with the central axis portion 5. The height of the long teeth 3 matches the height of the short teeth 4, so that the outer side surfaces of the long teeth 3 and the short teeth 4 match. Specifically, the height of the multiple long teeth 3 may be approximately 5 to 30 mm, and the height of the multiple short teeth 4 may be approximately 5 to 30 mm.

[0055] The middle axis 5 may be a truncated cone structure, the outer side surfaces of the plurality of long teeth 3 may be parallel to the outer side surface of the middle axis 5, and the outer side surfaces of the plurality of short teeth 4 may be parallel to the outer side surface of the middle axis 5. Correspondingly, the proximal and distal ends of a single short tooth 4 (corresponding to the proximal and distal ends of the drill body 2) may have substantially the same height, and the proximal and distal ends of a single long tooth 3 (corresponding to the proximal and distal ends of the drill body 2) may have substantially the same height. Further, a single short tooth 4 may have substantially the same height from its proximal end to its distal end, and a single long tooth 3 may have substantially the same height from its proximal end to its distal end. In the process of drilling with the diamond drill bit, the stability of the drill bit is ensured, and the smoothness and beauty of the inner core of the processed tapered hole can be ensured. The height of a specific position of a short tooth 4 and a long tooth 3 generally refers to the size of the position in the radial direction relative to the axis of the drill body 2. A plurality of long teeth 3 may also have substantially the same height, and a plurality of short teeth 4 may also have substantially the same height. When describing the height of a single short tooth 4, it may be described by the overall height of the single short tooth 4 (for example, it may be the average height of the single short tooth 4 in its extending direction). When describing the height of a single long tooth 3, it may be described by the overall height of the single long tooth 3 (for example, it may be the average height of the single long tooth 3 in its extending direction).

[0056] The long teeth 3 extend from the proximal end of the drill body 2 to the distal end of the drill body 2, and the short teeth 4 extend from the proximal end of the drill body 2 to the distal end of the drill body 2, and the long teeth 3 and the short teeth 4 are distributed alternately, which can ensure the flatness of the processed tapered hole; since the height of the long teeth 3 matches the height of the short teeth 4, the concentricity of the processed hole core can be further guaranteed.

[0057] The present invention also provides a processing platform, comprising a platform body and a grinding mechanism, wherein the grinding mechanism comprises the above-mentioned diamond drill bit;

[0058] A grinding station for grinding fused bricks can be provided on the platform body. During the process of processing conical holes in fused bricks, the fused bricks are usually placed at the grinding station, and the grinding mechanism drives the diamond drill bit to operate, so that the fused bricks placed on the grinding station can be processed to form conical holes. The processed conical holes have no cracks or other surface defects inside, and the inside of the conical holes is smooth and clean, which can meet the quality requirements of special glass kilns for fused bricks with conical holes.

[0059] The operation process of machining a conical hole on an electric fused brick by using the diamond drill bit provided by the present invention can be as follows:

[0060] S1: Determine the size of the tapered hole to be processed, and then use a straight drill bit to drill a through hole on the electric fused brick. The diameter of the through hole should be slightly smaller than the diameter of the end with a smaller cross-sectional area on the tapered hole to be processed;

[0061] S2: Install the connecting part 1 of the diamond drill bit provided by the present invention onto the grinding mechanism, place the fused brick on the grinding station of the platform body, and the grinding mechanism drives the diamond drill bit to operate, drilling the through hole on the fused brick into a conical hole.
