Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Conventional tempered glass thickness roughly has 1.1mm in the market, 0.7mm, and 0.55mm, 0.4mm is several, and the tempered glass of thickness below 1mm very easily spreads out and splits bifurcation in the time of cutting, and the sliver time is difficult to control especially in addition.
The scribing wheel of the fragile material that the utility model provides arranges two kinds or two or more miniature sunk structure and miniature cutting edges at the blade of a break bar, can better control spreading out of tempered glass and split and bifurcation, be particularly useful for strengthening layer thickness and reach tempered glass more than 30um.
As shown in Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), Fig. 1 (d), the scribing wheel of the fragile material that the utility model provides, comprise that the outward flange crest line L of V-arrangement cutting edge portion 1 has alternatively distributed cutting edge 4 and sunk structure 5 for mono-week by V-arrangement cutting edge portion 1, circular card 2 and the central shaft hole 3 for fixing scribing wheel of first surface a1, the second curved surface a2 and the L shaped one-tenth of outward flange crest line; Wherein, outward flange crest line L has the sunk structure 5 of at least two kinds of difformity sizes for mono-week, and each sunk structure 5 is along outward flange crest line L ordered arrangement or lack of alignment, and the number of every kind of sunk structure 5 can be the same or different; Between two cutting edges 4 that each sunk structure 5 is all adjacent, form the first cutting tip and the second cutting tip; The first cutting tip of at least part of sunk structure 5 both sides and the second cutting tip are used for cutting inside glass and line is split in formation, also has the first cutting tip of at least part of sunk structure 5 both sides and the second cutting tip split line in the extension of glass and avoid glass bifurcated and the formation of spreading out and splitting for controlling.
The utility model is by arranging the sunk structure 5 of difformity size and arrangement, can adapt to the tempered glass of different model, in effectively cutting inside glass, can control the formation of splitting the extension of line in glass and the control to the sliver time and avoiding glass bifurcated and spread out and split.
For example, having in the scribing wheel of two kinds of difform sunk structures: be respectively the first sunk structure 51 and the second sunk structure 52, and the size of the first sunk structure 51 is greater than the size of the second sunk structure 52.The first sunk structure 51 forms the first cutting tip 511 and the second cutting tip 512 with two adjacent cutting edges 4; The second sunk structure 52 forms the first cutting tip 521 and the second cutting tip 522 with two adjacent cutting edges 4.The first sunk structure 51 is responsible for incision inside glass and forms splitting line with the first cutting tip 511 and the second cutting tip 512 that two adjacent cutting edges 4 form, and the first cutting tip 521 that the second sunk structure 52 and two adjacent cutting edges 4 form and the second cutting tip 522 are responsible for controlling and are split the extension of line in glass and be responsible for the formation of avoiding glass bifurcated and spreading out and split.
Having in two or more difform sunk structures, for example: be respectively the first sunk structure 51, the second sunk structure 52 and the 3rd sunk structure etc., and the size of the first sunk structure 51 is greater than the size of the second sunk structure 52 and the 3rd sunk structure.The first sunk structure 51 forms the first cutting tip 511 and the second cutting tip 512 with two adjacent cutting edges 4; The second sunk structure 52 forms the first cutting tip 521 and the second cutting tip 522 with two adjacent cutting edges 4; The third sunk structure and adjacent two cutting edges form the first cutting tip and the second cutting tip etc.The first sunk structure 51 is responsible for incision inside glass and forms splitting line with the first cutting tip 511 and the second cutting tip 512 that two adjacent cutting edges 4 form, and the multiple cutting tip of remaining multiple sunk structure, cutting edge and formation is responsible for controlling and is split the extension of line in glass and be responsible for avoiding glass bifurcated and the formation of splitting of spreading out.
In the scribing wheel of the fragile material that the utility model provides, various sunk structures 5 can ordered arrangement or lack of alignment, for example: at least one (for example 1,2 or 3) little sunk structure 5 can be set between two adjacent large sunk structures 5, or, at least one (for example 1,2 or 3) large sunk structure 5 can be set between two adjacent little sunk structures 5; Wherein, the first cutting tip 511 of large sunk structure 5 both sides and the second cutting tip 512 split line for cutting inside glass and forming, and the first cutting tip 521 of little sunk structure 5 both sides and the second cutting tip 522 split line in the extension of glass and avoid glass bifurcated and the formation of spreading out and splitting for controlling.
Because the feature of tempered glass is that glass hard (HRC65Yi Shang) is large, internal stress value is large, be difficult to incision, and sliver be difficult to control, the more important thing is different manufacturers, different model glass adapt to cutting property difference very big; Therefore, the form that arranges that the utility model adopts large sunk structure 5 and little sunk structure 5 to combine, can control incision glass properties and control and split line and control that glass splits and time of burst.The effect of the cutting edge 4 of larger sunk structure 5 both sides is to control incision glass, and the Main Function of the cutting edge 4 of less sunk structure 5 both sides is to control the time of splitting line and controlling glass sliver.As can be seen here, the form that arranges that the utility model adopts large sunk structure 5 and little sunk structure 5 to combine is particularly useful for the cutting of the tempered glass that has strengthening layer.
In the scribing wheel of the fragile material that the utility model provides, the size of large sunk structure 5 is greater than the size of little sunk structure 5, the size of large sunk structure 5 is larger, can ensure the first cutting tip and the second cutting tip incision inside glass of its both sides and form to split line, the size of little sunk structure 5 is less, can not cut inside glass and form and split line, but the first cutting tip of little sunk structure 5 both sides and the second cutting tip can be controlled the formation of splitting the extension of line in glass and avoiding glass bifurcated and spread out and split.The proportion of the length of the length of little sunk structure 5 and large sunk structure 5 can be 1 ︰ 30～1 ︰ 1, and wherein preferably proportion can be 1 ︰ 4～1 ︰ 1.5.Meanwhile, the length range of large sunk structure 5 can be 6um～70um.Adopt sunk structure 5 and the difform sunk structure 5 of different size, can adapt to the cutting characteristic of different glass sample, to control the incision of glass and the sliver time of control glass.
