Abstract
The invention relates to the field of continuous casting cutting machines, in particular to an automatic sizing calibration method of a continuous casting cutting machine, which is characterized in that a PLC (programmable logic controller) respectively records the walking distance of a cutting machine encoder from the beginning to the end of cutting and the walking distance from the end of cutting to the return of a cutting machine to a cutting original point, after the cutting machine returns to the cutting original point, the PLC compares two sets of data, and once the deviation of the two sets of data is greater than a stop precision set value of the cutting machine, the PLC automatically sends an abnormal sizing alarm to remind an operator to confirm. The PLC is a self-control system of the original continuous casting cutting machine. Compared with the prior art, the invention has the beneficial effects that: the automatic checking device can automatically check the encoder of the cutting machine in real time, and once abnormity is found, an alarm is sent out in time to remind an operator to confirm, so that a large number of abnormal fixed-length casting blanks are avoided, and after the abnormal fixed-length casting blanks are generated, the abnormal fixed-length casting blanks can be found in time and rescue measures can be taken, so that the economic loss of enterprises is reduced.
Description
Technical field
The present invention relates to continuous casting cutter field, particularly to a kind of continuous casting cutter scale auto-collation.
Background technology
Continuous casting cutter scale is measured technology many employing encoders at present and is measured technology.Before cutting, cutting machine stops to be cut
Cut initial point, when the long measurement apparatus of base detect strand walked to need cutting length time, cutting machine screwdown gear starts
Pressure, at this moment cutting machine is in company with strand advanced in unison, and cuts.When cutting ends, cutting machine screwdown gear auto lifting
Rise, and record cutting machine travel distance this moment, return cutting initial point simultaneously, wait and cut order next time.Due to cutting machine
Working environment is very severe, is chronically in the middle of high temperature, high humidity environment so that the encoder of cutting machine, transmission cable, connection
Device often damages.After these component failure so that the accuracy of continuous casting fixed-length function can not get ensureing.If
Find to cause substantial amounts of abnormal scale strand not in time, bring huge economic loss to enterprise.
Summary of the invention
It is an object of the invention to provide a kind of continuous casting cutter scale auto-collation, cutting machine encoder is carried out in real time
Automatic Proofreading, once notes abnormalities, and sends warning in time, reminds operator to confirm, it is to avoid to produce substantial amounts of abnormal scale strand,
Reduce economic loss.
For achieving the above object, the present invention adopts the following technical scheme that realization:
Continuous casting cutter scale auto-collation, is recorded cutting machine encoder respectively from cutting initial point by PLC
Distance and cutting end of a period to the cutting machine walked during extremely cutting ends return the distance that cutting initial point is walked, when cutting machine returns
After switchback cuts initial point, two groups of data are compared by PLC, and once two groups of data deviations are more than the stopping accuracy of cutting machine
During setting value, PLC automatically sends abnormal scale and reports to the police, and reminds operator to confirm.
Described stopping accuracy setting value is ± 2cm.
Compared with prior art, the invention has the beneficial effects as follows:
Cutting machine encoder can be carried out in real time automatic Proofreading, once note abnormalities, send warning in time, remind operator
Confirm, it is to avoid produce substantial amounts of abnormal scale strand, can find in time after producing abnormal scale, and remind operator to take
Redemption means, it is to avoid cause waste and quality accident, reduce the economic loss of enterprise.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
In figure: 1-initial point photoswitch 2-baffle plate 3-encoder 4-cutting machine 5-PLC controller 6-reports to the police
The device 7-cutting wheel one 8-cutting wheel two 9-limit baffle plate 10-that meets meets limit photoswitch
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention one step of the present invention is illustrated:
Seeing that Fig. 1 is embodiment of the present invention structural representation, when cutting machine 4 is positioned at cutting initial point, car body overhead gage 2 will peace
The initial point photoswitch 1 being contained in track side blocks, and photoswitch is simultaneously emitted by an on-off model and passes to PLC 5
In, cutting machine current location is set as 0 after receiving signal by PLC 5, when the long measurement apparatus of base detects that strand has been gone
When going to the length needing cutting, cutting machine screwdown gear starts pressure, and at this moment cutting machine is in company with strand advanced in unison, on car body
Encoder 3 start to record the distance that cutting machine is passed by, when on cutting machine 4 cutting take turns 1 and cutting wheel 28 meet after, phase
Meeting limit baffle plate 9 to trigger and meet limit photoswitch 10, send limit signal in PLC, it is former that PLC controls cutting wheel 1 return
Point, returns after cutting wheel 28 continuation cutting 10 centimetres, is now judged to that strand completely cuts through, distance travelled by direction of advance
Being saved in PLC 5, cutting machine 4 starts to return.After in return course, the encoder 3 on car body starts to record cutting machine
Retreating row distance, when backing to cut initial point, initial point photoswitch 1 is blocked by car body overhead gage 2 again, and photoswitch is sent out again
Going out an on-off model and pass in PLC, PLC 5 receives before retreating the distance of traveling and original preservation after signal
Entering distance to compare, if result error is more than ± 2cm, then alarm 6 sends alarm signal, reminds operator to note different
Often, need to confirm through artificial, subsequent operations can be carried out.
Claims (1)
1. continuous casting cutter scale auto-collation, it is characterised in that recorded respectively by PLC cutting machine encoder from
During the extremely cutting end of a period of cutting initial point, distance and the cutting end of a period of walking return the distance cutting initial point walking to cutting machine, when
