Abstract
The mill skin grooving method that the invention provides a kind of grinding machine and the method repairing bending face glass, in grinding machine upper and lower disc surface, the mill skin that grinding force is different is installed, using the first mill skin that grinding force is big on the bent angle projection opposite face of bending, another side uses the second mill skin that grinding force is little；The fluting grid size of the first mill skin is 0.25 0.35 times of the second mill skin fluting grid size.The application makes lower millstone produce different grinding forces, and curved glass panel two sides is carried out grinding in various degree, then make crooked position grinding force big, and removal amount is big, and un-flexed position grinding force is little, and removal amount is little, thus reduces the flexibility of bending.
Description
Technical field
The present invention relates to flat glass processing technique field, especially, relate to the mill skin grooving method of a kind of grinding machine and use this mill
Bending face glass is repaired into the method for straight sheet non-defective unit by machine.
Background technology
The electronic product screen size such as computer, IPAD is relatively big, is adding the more difficult control of flatness in man-hour, is particularly needing after silk-screen
Baking, easily causes glass bending, and the shipment flexibility management and control usually required that requires to be 0.8, if exceeding this standard, assembling procedure
Then cannot be carried out assembling.Therefore, little in order to ensure to add man-hour glass bending fraction defective in rear workshop section, need to be before glass plain grinding operation
Flexibility is controlled within 0.2.
But in batch production process, due to many reasons such as jig error, mill error, operator's errors, often go out
The glass planar degree bad problem of bending more than 0.2 after existing flat-die.Batch is bent bad problem, currently without the work of a kind of maturation
Skill carries out batch and repairs bending.
Summary of the invention
Present invention aim at providing the restorative procedure of a kind of bending face glass, with irrecoverable after solving face glass bending
Technical problem.
For achieving the above object, the invention provides the mill skin grooving method of a kind of grinding machine, in grinding machine upper and lower disc surface, mill is installed
The mill skin that power of cutting is different, uses the first mill skin that grinding force is big on the bent angle projection opposite face of bending, and another side uses grinding force
The second little mill skin；
The fluting grid size of the first mill skin is 0.25-0.35 times of the second mill skin fluting grid size.
Preferably, 0.45-0.55 times of the groove depth of mill skin generally mill skin thickness.
Preferably, the fluting grid size of the first mill skin is 20 × 20mm, and the fluting grid size of the second mill skin is 70 × 70mm.
Utilize the grinding machine that above-mentioned mill skin grooving method prepares to the method repairing bending glass, bending glass is placed on grinding machine
Between lower surface, towards the first mill skin at the protrusion of bending；Open grinding machine, utilize mill skin that bending glass is repaired.
Preferably, the method comprising the steps of:
A, bending glass is placed between grinding machine upper and lower surface, towards the first mill skin at the protrusion of bending；
B, the fluting grid size of the first mill skin are 20 × 20mm, and the fluting grid size of the second mill skin is 70 × 70mm, curved
When grinding force at angle is 300 ± 40kg, grinding speed is 30 ± 5rpm, the grinding time is flexibility × coefficient, described system
The span of number is 500-1650.
Preferably, flatness be the grinding force of bent angle of 0.2-0.5 be 300 ± 40kg, grinding speed be 30 ± 5rpm, grinding
Time is 290 ± 40s.
Preferably, flatness be the grinding force of bent angle of more than 0.5 be 300 ± 40kg, grinding speed be 30 ± 5rpm, grinding
Time is 390 ± 40s.
Preferably, the grinding force of the first mill skin is ground by little curved parameter, and one side stock removal is 0.002mm；The grinding of the second mill skin
Power is ground by little curved parameter, and one side stock removal is 0.0005mm.
The method have the advantages that
The present invention is increased without new clamp tool, new board, can produce by existing board, only need to replace with lower mill skin,
Simple to operate, also ensure that the process requirements of grinding machine itself simultaneously.
Meanwhile, the bending defective products that present application addresses the generation of all glass industries can only scrap the phenomenon that can not do over again, Ke Yiying
Reclaim for all glass industries bending defective products；Use this technique reclaim bending can by within glass flatness reparation to 0.2,
Once reclaim yield more than 85%.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.Below
The present invention is further detailed explanation.
Detailed description of the invention
Hereinafter embodiments of the invention are described in detail, but the present invention can according to claim limit and cover multiple
Different modes is implemented.
For glass bending, the application installs, in the upper and lower disc surface of grinding machine, the mill skin that grinding force is different, protruding at the bent angle of bending
Using the first mill skin that grinding force is big on opposite face, another side uses the second mill skin that grinding force is little；Lower millstone is made to produce difference
Grinding force, curved glass panel two sides is carried out grinding in various degree, makes crooked position grinding force big, removal amount is big, non-
Crooked position grinding force is little, removal amount is little, so that the flatness of bending increases.
And it is possible to according to differently curved degree regulation upper lower burrs fluting size, flexibility is the biggest, the first mill skin fluting grid is the least,
Second mill skin fluting grid is the biggest；Flexibility is the least, and the first mill skin fluting grid is the biggest, and the second mill skin fluting grid is the least.Example
Such as 0.25-0.35 times that the fluting grid size of the first mill skin is the second mill skin fluting grid size, the beneficially first mill skin is more careful
The knee of glass is pressed close on ground, obtains more preferable ground effect.
Specific embodiment
1, the fluting grid size of red mill skin big for grinding force is set to 20 × 20mm, the white fluting grid grinding skin that grinding force is little
Size is set to 70 × 70mm；0.285 times that fluting grid size is white mill skin of red mill skin；
Groove depth generally grinds 0.45-0.55 times of skin thickness so that mill epidermis face can be suitable according to the surface configuration of grinding charge
Open or lock, changing surface configuration and gap width, thus polish the most smooth mellow and full.
In general, the color of mill skin is relevant with its implant, and the implant of red mill skin is relevant with the material such as cerium oxide, zirconium oxide,
The implant of white mill skin is relevant with zirconium oxide.The shore hardness of red mill skin is about 26-30, and the shore hardness of white mill skin is less, is about
5-7。
2, red mill skin is attached on grinding machine upper surface, is attached to grinding skin in vain on grinding machine lower surface；
3, bending glass is placed between grinding machine upper and lower surface, towards red mill skin at the protrusion of bending.
4, grinding machine is started.
Grinding process is divided into four steps, and the design parameter of each step is as shown in the table.
The little curved bent angle i.e. referring to that flatness is 0.2-0.5, big dactylogryposis flatness is the bent angle of more than 0.5.After above-mentioned grinding process, curved
Sheet can once reclaim yield more than 85% by within glass flatness reparation to 0.2.Concrete condition can see table.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
