Abstract
The invention provides a cutting knife wheel for fragile materials. The cutting knife wheel comprises a V-shaped cutting blade portion consisting of a first curved surface, a second curved surface and an outer edge ridge, a round disc surface and a central shaft hole. The outer edge ridge of the V-shaped cutting blade portion circumferentially has cutting blades and recessed structures distributed alternately. The outer edge ridge circumferentially has recessed structures of at least two different shapes and sizes, and the recessed structures are arranged in order or without order along the outer edge ridge. A first cutting tip and a second cutting tip are formed between each recessed structure and the corresponding two adjacent cutting blades. The first cutting tips and the second cutting tips on the two sides of at least one part of the recessed structures are used for cutting in glass and forming crack lines and the first cutting tips and the second cutting tips on the two sides of at least one part of the recessed structures are used for controlling the extension of the crack lines in the glass and preventing forking and over-cracking of the glass. The cutting knife wheel can effectively control the forking and over-cracking of fragile materials and is especially suitable for tempered glass.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Tempered glass thickness conventional in the market roughly has 1.1mm, and 0.7mm, 0.55mm, 0.4mm are several, and thickness very easily spreads out when cutting at the tempered glass of below 1mm and splits bifurcation, and the sliver time is difficult to control especially in addition.
The scribing wheel of fragile material provided by the invention arranges two kinds or two or more miniature sunk structures and miniature cutting edge at the blade of a break bar, better can control spreading out of tempered glass to split and bifurcation, be particularly useful for the tempered glass that strengthening layer thickness reaches more than 30um.
As shown in Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), Fig. 1 (d), the scribing wheel of fragile material provided by the invention, comprise the V-arrangement cutting edge portion 1, circular card 2 and the central shaft hole 3 for fixing scribing wheel that are formed by first surface a1, the second curved surface a2 and outward flange crest line L, 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; 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 often kind of sunk structure 5 can be the same or different; The first cutting tip and the second cutting tip is formed between two cutting edges 4 that each sunk structure 5 is all adjacent; First cutting tip of at least part of sunk structure 5 both sides and the second cutting tip split line for cutting inside glass and being formed, and also have the first cutting tip of at least part of sunk structure 5 both sides and the second cutting tip for controlling to split line extension in glass and avoiding glass bifurcated and the formation split of spreading out.
The present invention is by arranging the sunk structure 5 of difformity size and arrangement, the tempered glass of different model can be adapted to, while effective incision inside glass, can control to split line extension in glass and to the control of sliver time and avoid glass bifurcated and the formation split of spreading out.
In the scribing wheel with two kinds of difform sunk structures, such as: 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.First sunk structure 51 forms the first cutting tip 511 and the second cutting tip 512 with adjacent two cutting edges 4; Second sunk structure 52 forms the first cutting tip 521 and the second cutting tip 522 with adjacent two cutting edges 4.The first cutting tip 511 that first sunk structure 51 and adjacent two cutting edges 4 are formed and the second cutting tip 512 are responsible for cut inside glass and being formed splitting line, the first cutting tip 521 that the second sunk structure 52 and adjacent two cutting edges 4 are formed and the second cutting tip 522 is responsible controls to split line extension in glass and be responsible for avoiding glass bifurcated and the formation split of spreading out.
Have in two or more difform sunk structures, such as: be respectively the first sunk structure 51, 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.First sunk structure 51 forms the first cutting tip 511 and the second cutting tip 512 with adjacent two cutting edges 4; Second sunk structure 52 forms the first cutting tip 521 and the second cutting tip 522 with adjacent two 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 cutting tip 511 that first sunk structure 51 and adjacent two cutting edges 4 are formed and the second cutting tip 512 are responsible for cutting inside glass and are also formed and split line, and the multiple cutting tip of remaining multiple sunk structure, cutting edge and formation is responsible for controlling splitting line extension in glass and is responsible for avoiding glass bifurcated and the formation split of spreading out.
