Description
Technical field
The present invention relates to a kind of break bar and working method thereof of glass-cutting material.
Background technology
Along with the fast development of scientific and technological level, many fields require the thin thickness of glass, and hardness is big, and require for the cutting quality of glass also more and more higher, below be that example describes just with the used glass material of liquid-crystal display.
Being used for carrying out the common trait that the discal blade wheel of glass cutting has is: include the axis hole that cutting edge portion, break bar card and break bar center are used for installing cutter shaft.Wherein cutting edge portion is V-shaped, is convenient to cut glass, and the break bar material mainly is diamond, glomerocryst or polycrystalline diamond, Hardmetal materials etc.
The thickness of the used glass of liquid-crystal display is more and more thinner from 2mm to 0.1mm at present, hardness is increasing, specification of quality to the glass plane of rupture is also higher simultaneously, requirement such as the pressure when making cutting, incision technology, brisement efficient and accuracy requirement are also all higher, have proposed very big challenge for the research and development of parting tool-break bar.
Patent ZL01124992.7 and CN200680003956.0, and the patent ZL200410104603.2 of the applicant application etc. has proposed several microstructures in cutting edge portion processing, these several microstructures all make cutting edge portion produce periodic tongue and groove respectively, specifically referring to shown in Figure 6.Fig. 6 (a) to (f) is respectively the front view and the side-view of circular arc, rectangle and trapezoidal shape concaveconvex structure break bar.The principle of glass-cutting material is: apply certain pressure to break bar when cutting, make the part incision glass inside of blade projection, and sunk part can not be cut glass inside, has then formed the periodicity cut channel that is interrupted.Adjacent cut channel can produce under stress and split line, and is connected by splitting line, makes glass be cut open and brisement.
But the break bar of these several structures is when glass-cutting, and the topmost problem of existence is that the glass micropowder that produces when break bar can be cut is filled, and causes the break bar microstructure to stop up, and causes break bar to lose cutting power; The position that contacts with glass 11 in the sunk structure can do great damage to the line that splits that cutting produces in addition, shown in accompanying drawing 7 (d).Accompanying drawing 7 (a) is the synoptic diagram of circular-arc concaveconvex structure break bar glass-cutting and cutting effect; Fig. 7 (b) is the A among Fig. 7 (a)
7Partial enlarged drawing; Fig. 7 (c) is the B among Fig. 7 (b)
7Partial enlarged drawing.When glass-cutting, except producing cut channel 12 ', also can produce the radial line 13 ' that splits shown in accompanying drawing 7 (d).
For the working method of break bar, the method that proposes among the patent ZL200410104603.2 of the applicant's application and the other patent CN200680003956.0 with laser processing, the direction of laser beam is vertical with respect to the break bar card.When the processing micro structure of break bar outward flange crest line position, laser beam must run through material to cut off material in other words and could form microstructure, and the laser beam that proposes among the patent CN200680003956.0 is a closure or inc curve with respect to the running orbit of break bar card, must get off the whole excision of break bar material that is included in the curve during laser processing, reach and the isolating purpose of former break bar.This method can not be removed a zone with certain depth on material.
At above-mentioned these problems, the invention provides a kind of break bar and working method thereof that is used for glass-cutting and other glass material, the break bar of this kind new texture neither can result in blockage, can avoid again occurring damaging glass and avoid destroying and split line, and can obtain very high cutting quality.
