AI Technical Summary
Existing glass cutting tools lack chip removal and stress concentration treatment during the cutting process, resulting in glass chips flying everywhere and glass becoming brittle.
A glass cutting wheel was designed, which uses a chamfered and rounded recessed part connected to an arc channel for chip removal, and disperses stress concentration through the U-shaped or V-shaped inclined surface and recessed part.
It effectively removes glass fragments, reduces stress concentration, improves cutting results, extends the life of the cutting wheel, reduces wear, and enhances cost-effectiveness.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool technology, specifically referring to a glass cutting wheel. Background Technology
[0002] Tempered glass is a type of safety glass that is strong and safe to use. However, cutting and processing tempered glass can easily cause it to shatter. Therefore, glass must be cut to the appropriate size before tempering.
[0003] During the glass cutting process, significant stress occurs at the scratches, causing glass shards to fly wildly from both sides of the blade, a phenomenon commonly known as "shattering." These shattered glass shards can injure bystanders, and the shattered glass is particularly prone to breaking. Therefore, the type of blade used for glass cutting is especially crucial.
[0004] Currently, there is a lack of improvement in the handling of debris during glass cutting, and the stress concentration treatment is also ineffective. Utility Model Content
[0005] The technical problem this invention aims to solve is the lack of chip removal and stress concentration treatment in glass cutting tools.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a glass cutting blade wheel, including a blade wheel, a rotating shaft mounting port passing through the middle position of the blade wheel, and glass cutting blade assemblies arranged in a circular array at the circumferential position of the blade wheel with the largest diameter.
[0007] As an improvement, the glass cutting blade assembly includes a blade, a bevel, and a recess. The blade is located at the circumference of the maximum diameter of the cutting wheel. The bevel extends obliquely from the blade toward the shaft mounting opening. The recess is the extended end of the bevel and is chamfered.
[0008] As an improvement, an arc channel connects the two sets of symmetrically arranged inclined surfaces and recesses, and the arc channel is chamfered and rounded.
[0009] As an improvement, the two sets of inclined surfaces are arranged to sandwich a set of recesses, and the blade, inclined surfaces and recesses are arranged in a staggered array around the circumference.
[0010] As an improvement, the bevel and recess form an arcuate channel with the cut glass surface.
[0011] As an improvement, the shape formed by the inclined surface and the recess is either U-shaped or V-shaped.
[0012] As an improvement, the bevels and recesses are smoothed.
[0013] The beneficial effects of this utility model using the above structure are as follows: The glass cutting wheel proposed in this solution, by performing chamfered and rounded fine grinding on the recessed part, creates an arc channel connecting the recessed part with the two inclined surfaces of the cutting wheel. This channel plays a chip removal role during the cutting process of the cutting wheel, making it difficult for glass fragments to accumulate and producing a better cutting effect.
[0014] Furthermore, the new geometry better disperses stress concentration during the cutting process, reducing cracks in the glass. The recessed area has no cutting edge and is smoothed, resulting in a smooth surface that reduces cutting wear, makes the cutting break point more obvious, and achieves better splitting effect. This results in a longer service life, greatly improving the product's cost-effectiveness and reducing waste. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-3 As shown, the present invention proposes a glass cutting blade wheel, including a blade wheel 1, a rotating shaft mounting port 2 passing through the middle position of the blade wheel 1, and glass cutting blade assemblies 3 arranged in a circular array at the circumferential position of the blade wheel 1 with the largest diameter.
[0021] like Figure 3 As shown, the glass cutting blade assembly 3 includes a blade 4, a bevel 5, and a recess 6. The blade 4 is located at the circumference of the maximum diameter of the blade wheel 1. The bevel 5 extends obliquely from the blade 4 toward the shaft mounting port 2. The recess 6 is the extended end of the bevel 5.
[0022] like Figure 3As shown, two sets of symmetrically arranged inclined surfaces 5 and recessed parts 6 are connected by an arc channel 7, which is chamfered and rounded.
[0023] like Figure 1 , 2 As shown in Figure 3, two sets of inclined surfaces 5 are arranged to sandwich a set of recessed parts 6, and the blade 4 and the recessed parts 6 are arranged in an alternating array around the circumference; the inclined surfaces 5 and the recessed parts 6 form an arc channel with the glass surface being cut; the shape formed by the inclined surfaces 5 and the recessed parts 6 is either U-shaped or V-shaped; the inclined surfaces 5 and the recessed parts 6 are smoothed.
[0024] In practical use, the cutter wheel 1 is installed on the cutting equipment through the rotating shaft mounting port 2. When cutting glass, the glass cutting blade assembly 3 contacts the glass surface. During the cutting rotation, the arc channel 7 is set up by connecting the recessed part 6 and the two inclined surfaces 5. The arc channel 7 has been beveled and finely ground, so that the arc channel 7 plays a chip removal role during the cutting process of the cutter wheel 1. At the same time, there is no cutting edge in the inclined surface 5 and the recessed part 6, which reduces wear and improves the service life of the cutter wheel 1. Finally, the glass is cut under the work of the blade 4.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
