Abstract
The utility model relates to a cutting knife wheel with an 83-degree cutting groove. The cutting knife wheel is used for a glass cutting machine tool, and the glass cutting machine tool comprises a rotating main shaft, wherein the disc-like cutting knife wheel is mounted at an end of the rotating main shaft; A plurality of cutting edges are arranged at a circumferential part of the cutting knife wheel; cutting grooves are formed between adjacent cutting edges, and the cutting grooves are V-shaped; and the cutting groove V-shaped parts of the cutting knife wheel are at an angle of 83 degrees, and the width of the cutting edges is twice the arc width of the cutting groove V-shaped parts. By adopting the cutting method disclosed by the utility model, glass chips generated after cutting are not adhered to the glass surface, thus reducing scratches of the glass surface.
Description
Technical field
The utility model relates to a kind of scribing wheel 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 large, and require also more and more higher for the cutting quality of glass.
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 is mainly diamond, glomerocryst or polycrystalline diamond, Hardmetal materials etc.
The thickness of liquid-crystal display glass used 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, make the requirement such as pressure, incision technology, brisement efficient and the accuracy requirement in when cutting also all higher, have higher requirement for cutting method and cutting tool.
Existing break bar 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; Can the line that splits that cutting prod produces be done great damage with the position of glass contact in sunk structure in addition.
For above-mentioned these problems, the utility model provides a kind of scribing wheel for glass-cutting, and this kind break bar life-span is long; The break bar cutting part can not stop up; Split line and can not damage what cutting prod produced; The cullet that produces after cutting can not be attached to glass surface, has reduced the cut of glass surface.
The utility model content
The purpose of this utility model is to provide a kind of scribing wheel of glass-cutting, and this kind break bar life-span is long, and the break bar cutting part does not stop up, and avoid damaging glass and destruction splits line, and break bar that can the high quality glass-cutting.
A kind of grooving angle is the scribing wheel of 83 degree, this scribing wheel is used for the glass cutting lathe, the glass cutting lathe comprises live spindle, the live spindle end is equipped with the plate-like scribing wheel, this scribing wheel circumferential part is provided with a plurality of cutting edges, is grooving between the adjacent cutting sword, and grooving is V-shaped, the grooving V-shape portion of this scribing wheel is 83 degree, and the cutting edge width is two times of grooving V-shape portion circular arc width.
The cutting edge that the scribing wheel circumferential part arranges is circular arc concentric with scribing wheel and that radius equates.
The advantage of this scribing wheel is:
Certain thickness glass is cut, and through overtesting, the break bar cutting part can not stop up, and cullet is effectively discharged; Cutting prod produces splits line and can expect, has guaranteed cutting quality; The cullet that produces after cutting can not be attached to glass surface, has reduced the cut of glass surface.
Description of drawings
The grooving V-shape portion that Fig. 1 is is the cutting break bar schematic diagram of 83 degree.
Embodiment
Embodiment 1
With stable being placed on the machining tool platform of glass horizontal, use is cut around the shaft break bar and is streaked at glass surface, and glass is cut apart.Be the glass of 1.1T (1.1mm) for thickness, cutting pressure 0.03 ± 0.005Mp/cm
2, hilted broadsword pressure 0.020 ± 0.005Mp/cm
2, the cutter degree of depth (mm) 0.10 ± 0.02mm under TFT, cutting speed in feet per minute (m/min) 25 ± 20m/min, depth of cut specification (um) 50 ± 30um utilizes cutting edge to complete to treat the cutting of glass-cutting.
By changing the angle of the cutters gear teeth, to test, as seen after the break bar cutting after improvement, cullet reduces, visual, substantially is present in the line of cut position, has improved the quality of product; Life-span can reach 15000M, but the break bar material do not change, and increases by 6.5 times (before improving, the break bar life-span is 2000M) than the break bar life-span before improving.The thrust surface when life-span increases long former because break bar cutting increases, and the break bar wearing and tearing reduce.
Embodiment 2
With stable being placed on the machining tool platform of glass horizontal, use is cut around the shaft break bar and is streaked at glass surface, and glass is cut apart.Be the glass of 0.7T (0.7mm) for thickness, cutting pressure 0.045 ± 0.005Mp/cm
2, hilted broadsword pressure 0.030 ± 0.005Mp/cm
2, the lower cutter degree of depth (mm) 0.15 ± 0.02mm, cutting speed in feet per minute (m/min) 25 ± 20m/min, depth of cut specification (um) 80 ± 30um utilizes cutting edge to complete to treat the cutting of glass-cutting.Through test, cutting is attached to glass surface without glass chip in order, and the sliver direction meets the requirements.
By changing the angle of the cutters gear teeth, to test, as seen after the break bar cutting after improvement, cullet reduces, visual, substantially is present in the line of cut position, has improved the quality of product; Life-span can reach 15000M, but the break bar material do not change, and increases by 6.5 times (before improving, the break bar life-span is 2000M) than the break bar life-span before improving.The thrust surface when life-span increases long former because break bar cutting increases, and the break bar wearing and tearing reduce.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
