Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drill bit structure of an alloy Y-shaped glass drill. Background Art

[0002] In the fields of building material installation and home decoration, drilling holes in ceramic tiles is a common and crucial task. Traditional drilling nail designs, especially the widely used cross-shaped drill bit, have demonstrated excellent versatility in a variety of materials. With its four symmetrically distributed cutting edges, the cross-shaped drill bit is able to effectively drill holes in a variety of materials, including some relatively hard surfaces. However, when it comes to certain hard and brittle materials such as ceramic tiles, the user experience of traditional cross-shaped drill bits needs to be improved.

[0003] During the drilling process, traditional cross-shaped drill bits may suffer from low cutting efficiency due to the dispersion of the cutting edge. At the same time, due to the uneven distribution of cutting force, cracks or breakages are easily generated on the surface of the tile, affecting the drilling quality and aesthetics. In addition, the chip removal channel design of the cross-shaped drill bit may not be efficient enough for tile drilling operations, especially when encountering small ceramic fragments. Poor chip removal may cause blockage of the drill hole, further affecting the operation efficiency and the service life of the drill bit. Therefore, in order to improve the drilling efficiency, this device proposes a drill bit structure of an alloy Y-shaped glass drill. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a drill bit structure of an alloy Y-shaped glass drill.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A drill bit structure for an alloy Y-shaped glass drill includes a main rod, a connecting portion is provided at the bottom end of the main rod, and the connecting portion is installed on a drilling device. The top end of the main rod is provided with a drilling portion, and the drilling portion includes three cutting blades. The three cutting blades are arranged in a ring array along the axis of the main rod, so that the drilling portion is arranged in a "Y" shape.

[0007] The above technical solution further includes: the cutting edge side of the cutting blade is arc-shaped.

[0008] Furthermore, the cutting edge side of the cutting blade is arc-shaped, and a plurality of notches are provided on the arc-shaped side wall.

[0009] Furthermore, the inner side of the notch is arc-shaped.

[0010] Furthermore, three spiral grooves are provided on the side wall of the main body rod, and the three spiral grooves are arranged in a circular array along the axis of the main body rod.

[0011] Furthermore, the top of the main rod between two adjacent cutting blades is polished to form a polished surface.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the present invention, the drill head is composed of three cutting blades arranged in a "Y" shape, which realizes the concentration of cutting force and the improvement of sharpness. The design of the "Y"-shaped drill bit optimizes the chip removal channel, making the chip removal process smoother. In the tile drilling operation, even if small ceramic fragments are encountered, the "Y"-shaped drill bit can quickly discharge them, avoiding the problem of drilling blockage caused by poor chip removal.

[0014] 2. In the present invention, the "Y"-shaped drill bit reduces friction and heat accumulation during the cutting process, reduces the wear rate of the drill bit, and thus enhances the durability of the drill bit. This means that under the same operating conditions, the "Y"-shaped drill bit can continue to operate efficiently for a longer period of time, reduces the frequency of drill bit replacement, and reduces operating costs.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] Refer to the attached Figure 1 and 3The present invention proposes a drill bit structure of an alloy Y-shaped glass drill, which includes a main rod 10. The bottom end of the main rod 10 is provided with a connecting portion 20, and the connecting portion 20 is installed on the drilling equipment; wherein, the present device does not improve the part of the connecting portion 20, and its connection method with the drilling equipment is the existing technology, which will not be repeated here.

[0024] The top of the main rod 10 is provided with a drilling portion, which includes three cutting blades 31. The three cutting blades 31 are arranged in a circular array along the axis of the main rod 10, so that the drilling portion is arranged in a "Y" shape. The provision of three cutting blades 31 optimizes the chip removal channel, making the chip removal process smoother. During the tile drilling operation, even if small ceramic fragments are encountered, the "Y"-shaped drill bit can quickly discharge them, avoiding the problem of drilling blockage caused by poor chip removal.

[0025] The blade side of the cutting blade 31 is in an arc shape; wherein, the connection between the tops of the three cutting blades 31 is tapered, and the three cutting blades 31 form a whole, so that the drilling work can be carried out efficiently and stably.

[0026] Three spiral grooves 11 are provided on the side wall of the main rod 10 , and the three spiral grooves 11 are arranged in a circular array along the axis of the main rod 10 ; wherein, the spiral grooves 11 can facilitate chip removal and improve the fluency of drilling.

[0027] The top of the main rod 10 is located between two adjacent cutting blades 31 and is polished to form a polished surface 12; wherein, the cutting blade 31 is welded to the top of the main rod 10. In order to avoid the phenomenon of damaging tiles during drilling due to the outer diameter of the main rod 10 being too large, the excess part of the main rod 10 between the two cutting blades 31 is polished here to further improve the smoothness of drilling.

[0028] In this embodiment, when using the device, first connect the connecting portion 20 of the device to the drilling equipment, and with the cooperation of the cutting blade 31 of the drilling portion, the surface of the tool such as the tile can be drilled;

[0029] The drill head of this device is composed of three cutting blades arranged in a "Y" shape, which achieves the concentration of cutting force and the improvement of sharpness.

[0030] Example 2

[0031] like Figure 2 As shown, based on the first embodiment, the cutting edge side of the cutting insert 31 is arc-shaped, and a plurality of notches 41 are opened on the arc-shaped side wall, and the inner side of the notches 41 is arc-shaped.

[0032] In this embodiment, a notch 41 is provided on the outer wall of the cutting blade 31, so that the outer wall of the cutting blade 31 is serrated, which reduces the resistance caused by wind resistance and friction, and at the same time improves the sharpness of the cutting surface, so that the drilling work can be carried out efficiently and stably.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
