Description

Technical Field

[0001] This utility model relates to the field of cutting wheel technology, and in particular to a cutting cutting wheel. Background Technology

[0002] In glass cutting, a cutting wheel is typically used to create cutting lines on the glass surface, inducing beneficial linear microcracks. These microcracks then separate when they reach a certain size, allowing them to propagate in two directions: transverse and longitudinal. Generally, cracks caused by transverse forces are called transverse cracks, and those caused by longitudinal forces are called longitudinal cracks. In glass cutting, smaller transverse cracks result in higher glass cutting strength, while deeper longitudinal cracks indicate better cutting wheel penetration. Current technology generally uses circular cutting wheels, which not only have poor penetration but are also prone to slippage during cutting. Toothed cutting wheels, on the other hand, suffer from problems such as tooth breakage, tooth damage, and short service life. Therefore, improving the stability of the cutting wheel during glass cutting, reducing the probability of abnormalities, and facilitating chip removal during the cutting process are problems that need to be solved by those skilled in the art. Utility Model Content

[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figures 1-6 As shown, this embodiment provides a cutting wheel, including a main body 10 and a cutting part. The cutting part is arranged circumferentially along the main body 10. The cutting part is provided with a plurality of tooth grooves 30, and each tooth groove 30 is recessed with a plurality of grooves 301, and the grooves 301 are semi-circular grooves.

[0031] Specifically, in this embodiment, a plurality of toothed grooves 30 are provided on the cutting section, and a plurality of recesses 301 are provided within the toothed grooves 30. This not only facilitates chip removal but also effectively disperses cutting stress, thereby reducing the risk of localized cracking of glass materials during the cutting process. Furthermore, the recesses 301 are designed as semi-circular grooves to deepen the depth of the toothed grooves 30, and their smooth structure facilitates smooth chip removal, preventing blockages and jamming during the cutting process, thus improving the cutting yield. Simultaneously, in this embodiment, a cutting section is provided circumferentially on the main body 10, and micro-cracks are created on the glass using the cutting section. The toothed grooves 30 effectively prevent problems such as blade slippage, tooth breakage, and tooth fracture, thereby extending its service life.

[0032] The specific structure of the cutting wheel in this embodiment will be described below.

[0033] like Figures 1-3 As shown, in this embodiment, the cutting wheel includes a main body 10, a connecting part 20, and a cutting part, with the main body 10 connected to the cutting part via the connecting part 20. Specifically, in this embodiment, the cutting part is arranged circumferentially along the main body 10, and a connecting part 20 is connected to each side of the cutting part along the axial direction of the main body 10. The two connecting parts 20 are symmetrically arranged to form the overall structure of the cutting wheel, enabling the cutting wheel to perform cutting operations using the cutting part. Specifically, the connecting part 20 is inclined, with its high end connected to the main body 10 and its low end connected to the cutting part, thereby ensuring a smaller contact area between the cutting part and the items to be cut, thus improving cutting efficiency.

[0034] Combination Figures 4-6 As shown, in this embodiment, the outer diameter of the cutting wheel is set to D, and the value of D ranges from 2mm to 6mm. Further, the thickness of the cutting wheel is set to H, and the value of H ranges from 0.65mm to 1.2mm. Correspondingly, the included angle between the extended lines of the two connecting portions 20 on both sides of the cutting part is set to θ1, and the value of θ1 ranges from 90° to 160°, thereby determining the main cutting edge angle of the cutting wheel. For example, in this embodiment, the outer diameter of the cutting wheel is set to 2.1mm, the thickness H of the cutting wheel is set to 0.65mm, and θ1 is set to 115°. In other embodiments, other values ​​can be set as needed, and this is not limited here.

[0035] Optionally, an inner hole 101 is provided axially through the center of the main body 10, and the diameter of the inner hole 101 is set to d, the value of d being in the range of 0.8mm-1.2mm, which can be used for installation to ensure stable cutting. For example, in this embodiment, the diameter d of the inner hole 101 is set to 0.8mm, but it can also be set as needed in other embodiments.

[0036] like Figure 6As shown, in this embodiment, the cutting section is provided with a plurality of toothed grooves 30, and the tooth pitch of two adjacent toothed grooves 30 is the same, so as to facilitate cutting and chip removal and ensure the stability and accuracy of cutting. Further, each toothed groove 30 is recessed with a plurality of grooves 301, and the grooves 301 are semi-circular grooves. Each groove 301 is independently distributed, and the tooth pitch of two adjacent grooves 301 is the same, so as to ensure the stability of cutting, facilitate the dispersion of cutting stress, and avoid the risk of localized cracking of the cut material. For example, in this embodiment, three grooves 301 are provided, and the three grooves 301 form a quincunx structure to facilitate the discharge of material debris. For example, the tooth pitch L of two adjacent toothed grooves 30 satisfies L≥10um.

[0037] Specifically, the included angle between the center lines of the two grooves 301 on the left and right sides of each tooth groove 30 is set to θ2, and the value of θ2 is in the range of 110°-120°. For example, in this embodiment, θ2 is set to 110°, but it can be set as needed in other embodiments. Further, the tooth groove 30 is set as an arc-shaped groove, and the inner diameter of the tooth groove 30 is set to R, and the value of R is in the range of 0.01mm-0.03mm. For example, in this embodiment, the inner diameter R of the tooth groove 30 is set to 0.025mm, but it can be set as needed in other embodiments. Correspondingly, the inner diameter of the groove 301 is set to r, and the value of r is in the range of 0.005mm-0.01mm. For example, in this embodiment, the inner diameter r of the groove 301 is set to 0.0075mm, but it can be set as needed in other embodiments. Optionally, the depth of the tooth groove 30 is set to h, and h satisfies h = R + r, where the inner diameter of the tooth groove 30 is set to R, and the inner diameter of the groove 301 is set to r. Specifically, the value of h is in the range of 0.01mm-0.02mm.

[0038] Therefore, in this embodiment, the cutting wheel improves the cutting section compared to a traditional cutting wheel. It not only features toothed grooves 30, but also a semi-circular groove 301 recessed within the toothed grooves 30. This facilitates the timely removal of glass fragments during cutting and effectively reduces clogging and jamming during the cutting process. By dispersing cutting stress, it reduces the risk of localized glass breakage and improves cutting yield. In other embodiments, the shape of the groove 301 within the toothed grooves 30 can also be set to other shapes such as square or V-shaped as needed.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
