Set 6.
Embodiment
In Fig. 1, a kind of cold end produces wire cutting bridge pressure closed-loop control system, including man-machine interface 1, programmable control
Device 2 processed, cutting pressure controller 3, break bar 4, it is characterized in that：Man-machine interface 1 is connected with programmable controller 2, programmable
Controller 2 is connected with cutting pressure controller 3, and cutting pressure controller 3 is connected with break bar 4, and the cutting track of break bar 4 is provided with
DMS deformeters 5.
In preferable scheme, described DMS deformeters 5 are used to measure pressure of the scribing wheel to glass.
In preferable scheme, described programmable controller 2 control cutting pressure controller 3 applies constant to break bar 4
Pressure.
In preferable scheme, the described outer wall of break bar 4 is provided with break bar set 6, and the break bar set 6 is round-like structure body, knife
Round platform through hole 7 is additionally provided with wheel case 6, the side angle of inclination of round platform through hole 7 is identical with the side angle of inclination of break bar 4, break bar
The angle of inclination for covering 6 lateral surfaces is different from the side angle of inclination of break bar 4.
In Fig. 2, scribing wheel is mainly in stress caused by inside glass：Downward pressure F and perpendicular to break bar
The component F1 of angle.Downward pressure F is the required pressure of cutting；And influence point for being perpendicular to scribe-wheel angle of cut quality
Power F1.It is inconsistent due to scribe-wheel angle, F1 act on inside glass direction and size it is also different.
For the F1 component that the break bar of low-angle is acted on glass because vertical with scribe-wheel angle, it produces the horizontal stroke for being unfavorable for cutting
It is larger to component.When producing thin glass, because scribe-wheel angle is small, the break bar of low-angle can cut out knife under less pressure
Print and good break disconnected effect so as to realize.In the process, transverse component very little caused by F1 component, to caused by cut quality
Influence also very little；If continuing to increase the pressure of break bar, F1 component also can be increasing, and its caused transverse component will destroy
The micro-crack of glass section, or even cullet bits are produced in break bar both sides；If continue intensified pressure on this basis, then institute
The increased pressure overwhelming majority is all transformed into transverse component and discharged.
Similarly, if break bar when producing heavy sheet glass from low-angle is cut, because the transverse direction of low-angle break bar point
Power is too big, and when cutting pressure increases to a certain extent, it is substantial amounts of that transverse component can produce break bar both sides because of the plane effect of scraping
Cullet are considered to be worth doing, so as to constantly release the magnetic valve power being applied on break bar, the lower pressure for making break bar really act on glass
Very little, it can not cut out effectively and be advantageous to break disconnected tool marks.So in summary, the break bar of low-angle can only be thin for cutting
Glass, and can not be used for cutting heavy sheet glass.Therefore selection sets dismountable break bar set on break bar outer wall, according to different sizes
Glass production need carry out scribe-wheel angle selection, so as to avoid the generation of the above situation.
The downward stress F values applied to glass, program controller PLC are needed in the input break bar of programmable controller 2 first
Device 2 controls cutting pressure controller 3, and cutting pressure controller 3 ensures that the force of break bar 4 is constant, when power F has changed, DMS
Deformeter 5 can transmit the signal sensed to cutting pressure controller 3, and cutting pressure controller 3 receives and programmable
The different stress signal of controller 2, therefore regulation break bar 4 readjusts the pressure F to glass, F is reached setting value, so as to protect
Demonstrate,prove in whole cutting process, pressure it is constant, and then ensure that cutting operation is normally carried out.
Using said structure, the constant of break bar pressure is realized, avoids glass caused by existing feedback-less control system
Rupture of the glass in cutting process, tool marks can not enough break the occurrence of splitting etc. other into two with one's hands deeply, ensure that ultra-thin glass is given birth to
Production is normally carried out.
