Abstract

The utility model provides a glass-cutting wheel, when cutting the base plate by the inner face, the cut mark soaks to the inner face that is close to the base plate by the bottom of cutting the line, and can not break up (break up in or break up outward) in the face of cut apart production. The solution of the present invention is to adopt the following constitution, that is, to be provided with: a disc (2) which is a through hole having a support shaft at the center; a cutting part (3) which is provided with the circumferential edge parts on the two sides of the disc in a mutually inclined mode; a cutting edge part (5) which is arranged in a zigzag point shape at the circumferential edge part by a concave part (4), wherein the concave part (4) is arranged towards the two cutting parts at the equal interval position of the circumferential edge part of the disc; and a cutting groove (6) connecting both sides of the deep portion of each recessed portion, and making an angle of the cutting groove in the circumferential direction an impact applying projection (7).

Description

Glass-cutting wheel

Technical field

It is to be rotated in the state of being crimped on glass substrate plate face, so in base the utility model relates to a kind of cutting wheel Plate plate face draws upper score line (cutting line).

Background technique

Cutting train used in for the above-mentioned purpose makes two sides circle relative to the disks such as cemented carbide or sintering diamond Peripheral edge portion is cut each other angularly, and the crest line complete cycle edge in the two bevellings portion forms dotted existing V shape ditch, makes the ditch Basic point when ditch (formed angle) protrusion (cutter) over head and ears substrate surface, so draw upper score line (referring for example to patent text It offers 1).

Utility model content

[the utility model project to be solved]

Also, forming dotted presence in the crest line complete cycle edge of two bevellings of disk two sides according to the cutting wheel of patent document 1 V shape ditch, and make the protrusion of the ditch over head and ears substrate surface, so draw upper score line.

But vibration can reach score face by V shape ditch, be impregnated with rate deeply though can obtain, can there is score face because of pressure increase Rupture is led to the problem of, clast is generated and disperses and generate and burst apart.

It, can be because rotating the V cut simultaneously with wheel in score especially when score wheel circumference outer diameter forms a large amount of V word ditches Word ditch and so that vibration is reached score face, be impregnated with the deeper wheel of rate though can so become, more increase pressure then more has following ask Inscribe: score face generates rupture, generates the probability raising that clast disperses and generates divisional plane generation fragmentation when bursting apart, dividing (folding is cut) And the probability for becoming defective products improves.The fragmentation is divided into interior fragmentation, outer fragmentation, wherein so-called fragmentation mean score face it is not smooth and It is defective.

Therefore, the project of the utility model is solved the above problems in the case where improving score and being impregnated with rate.

[to the means to solve the problem]

In order to solve the above problems, the utility model uses following composition:

A kind of glass-cutting wheel, it is characterized in that being provided with

Disk is the through hole for having fulcrum at center；

Cutting portion is that the circumferential edge portions of above-mentioned disk two sides are arranged in a manner of each other angularly；

Cutting edge portion, in aforementioned circumferential edge portions zigzag the dotted presence by concave portion, above-mentioned concave portion is by upper The position at equal intervals for stating the circumferential edge portions of disk is arranged toward above-mentioned two sides cutting portion；And

Ditch portion is cut, the deep two sides of each above-mentioned concave portion are linked；

And make above-mentioned cutting ditch portion in the angle of circumferencial direction impact imparting protrusion.

[the effect of utility model]

It is on one side with rotation (rotation) disk and by each such as above-mentioned, glass-cutting wheel according to the present utility model Cutting edge portion from substrate surface toward inner face side cut, on one side carry out the processing of score line, and can by disk two sides cutting portion and The clast etc. generated with processing is discharged well.

Then, with the processing of score line, by two crest lines of ditch portion protrusion and form score line in cutting portion, can be in The ditch of the score line assigns impact, and is impregnated with cut mark to the inner face close to substrate.

Folding can therefore cut, and (segmentation) is extremely smooth, especially cut mark system up to close substrate inner face, so that with segmentation in The probability that divisional plane generates fragmentation (fragmentation is divided into outer fragmentation and interior fragmentation) reduces, and has the special effect for preventing defective products from generating Fruit.

Specific embodiment

Illustrate the implementation form of the utility model then according to FIG. 1 to FIG. 5.A shown in FIG. 1 to FIG. 5 is glass-cutting wheel.

Above-mentioned glass-cutting wheel A composition is as follows, is the through hole for having fulcrum at center that is, being provided with disk 2 1；Cutting portion 3 is that the circumferential edge portions of 2 two sides of disk are arranged in a manner of each other angularly；Cutting edge portion 5 relies on concave portion 4 And in the dotted presence of aforementioned circumferential edge portions, the concave portion 4 is from the circumferential edge portions of above-mentioned disk 2 toward above-mentioned two cutting portion 3 Complete cycle at equal intervals position and be arranged；And cutting ditch portion 6, link the deep two sides of above-mentioned each concave portion 4；And make the cutting ditch portion The angle of the crest line of 6 circumferencial direction is that impact assigns protrusion 7.Above-mentioned disk 2 is such as using hard alloy.

As shown in Figure 2,3, 4, above-mentioned cutting portion 3 tilts incision (side from circumferential edge portions toward 2 two sides center position of disk Edge is relatively thin and more thicker toward center position).

As shown in Figure 2,3, 4, above-mentioned concave portion 4 between the cutting edge portion 5 of front and back toward the semi arch ditch of 2 two sides of disk Item, by the ditch item concave portion 4 and so that the clast etc. when 5 score of cutting edge portion is fallen on 2 two sides surface side cocurrent of disk freely Discharge.

As shown in figure 4, above-mentioned 6 system of cutting ditch portion is to cut the concave portion 4,4 that the end face of ditch portion 6 is connected to 2 two sides of disk Mode and be arranged, the angle (crest line) of 5 side of cutting edge portion of the cutting ditch portion 6 becomes impact and assigns protrusion 7.

In this way, as shown in fig. 6, if by score, cutting edge by the glass-cutting wheel A of substrate a surface pivots Portion 5 can be cut from the surface substrate a toward inner face and score.

At this point, the cutting ditch bottom through score can be assigned protrusion 7 by impact assigns impact to the score ditch of substrate a, therefore, Cut mark can be made to be impregnated with by score ditch bottom to close to substrate a inner face by the impact.

Therefore, folding cuts (segmentation) extremely smoothness, and can form the folding relative to the divisional plane that the plate face of substrate a is right angle It cuts.Also can roll over and cut in the case where divisional plane is without outer fragmentation, interior fragmentation, can remove because generate above-mentioned outer fragmentation or in fragmentation due to become not The problem of non-defective unit, wherein so-called fragmentation means that score face is not smooth and defective.
