Data are acquired in TCU, are monitored for operator, are completed the technology controlling and process function of cold bed.
In this embodiment, the control equipment for continuously running cold bed is realized by waveform generator and position control.
The main function of waveform generator is to calculate that out position is given and speed preset by displacement curve dynamic, as position control
Input, according to position, given, position feedback and speed preset control speed to position control, and the two combines reality
Now accurate position control.There are three types of working method, position control mode, speed control mode and tracking moulds for waveform generator
Formula is respectively used to realize location control, speed control and the positioning Correction and Control under speed tracing.In high stick continous way cold bed
In control, cold bed is started as unit of a steel billet first, is continuously run later, is rolled and is stopped after a steel billet to connecing steel
Position.The multiple length of each steel billet can be divided into a steel, intermediate steel and tail steel three parts in this way.
Specifically, Figure 11 is the control principle schematic diagram of the control equipment in the specific embodiment, Figure 11 is please referred to, at this
In embodiment, when multi-length shear shearing, according to the multiple lengths of this and next time, this cycle of operation is calculated, to determine
The speed of service of cold bed movable tooth.Since the variation of speed is the process of a gradual change, acceleration can not be infinitely great, therefore for
There is the alternate position spike as caused by velocity variations for each period, using this alternate position spike as position correction amount in system, thus
It realizes synchronous with the period to position.The amendment of position is carried out in two times, after receiving steel order, carries out preliminary repair
Just;It is accurately corrected when rotary drum starts movement.
Figure 12 is the working curve of waveform generator and position control signal in specific embodiment provided by the invention
Figure, please refers to Figure 12, and in this embodiment, the Shoudu Iron and Steel Co of each steel billet uses station-keeping mode, and pre-cooling is to compensate start-up course
The time needed, intermediate steel make movable tooth stop at zero-bit using the tracing mode for adding position correction, tail steel using station-keeping mode.
Specifically, Figure 13 is the schematic diagram for the page that steel billet in the specific embodiment is Shoudu Iron and Steel Co time control control equipment, every
The first Zhi Gang of a steel billet, cold bed movable tooth are run with station-keeping mode, and PMove rising edge starts positioning movement, and PosSet is cold bed zero
Position, since movable tooth needs to make up the time for reaching setting speed with certain slope (R) from zero-speed starting, movable tooth is mentioned by slope
Preceding starting, cold bed locating speed VelSet=V1=360/ (length information/bar speed).Cold bed movable tooth reaches V1's from static
Time T1=V1/R, from the static angle P1=0.5 × V1 × T1 for reaching V1 to speed and running, cold bed movable tooth, which is run one week, is
360 degree, T2=(360-P1)/V1, running time T 3=T1+T2- (length information/bar speed) in advance;Simultaneously
AuxStartCommand order is 1, need to also be after continued access steel because being first Zhi Gang, therefore cold bed movable tooth continues to run.
Figure 14 is the schematic diagram for the page that the steel billet in specific embodiment provided by the invention is intermediate steel time control control equipment,
When intermediate steel connects steel, cold bed movable tooth is run with tracing mode, and Tracking rising edge starts tracing mode, cold bed tracking velocity
VelTrk=V2=360/ (length information/bar speed), while tentatively estimating cold bed movable tooth connects steel with tracking velocity to next time
When location error Perr1=(Pnow+ (length information/bar speed) × V2) -360, Pnow be current position;In rotary drum
Calculating position error Perr2=(Pnow+ (rotary drum actuation time) × V2) -360 again when throwing steel, is set by PosTrk
Fixed, tracing positional is updated by SetPos rising edge, and the acceleration of movement sets the automatic correction position error of system by AccSet,
Rotary drum calculates location error when cold bed movable tooth connects steel with tracking velocity to next time again while being modified when starting.
Figure 15 is the schematic diagram for the page that steel billet in specific embodiment provided by the invention is tail steel time control control equipment,
When tail steel, in station-keeping mode movement, PMove rising edge starts positioning movement, and position location is set by PosSet=0, fixed
Bit rate is set by VelSet.AuxStartCommand order is 0, and cold bed movable tooth stops in situ after having run this period,
Etc. the multiple length of next steel billet waiting.
Figure 17 is that the main picture function for the control system for continuously running cold bed in specific embodiment provided by the invention is shown
It is intended to, as shown in figure 17, cold bed movable tooth picture can choose cold bed work in continuous mode or start-stop mode.The operation of cold bed
Speed is to set when manual on picture, and in automated manner, speed calculates automatically in program.A channel or channel B
Cold bed alignment distance setting refers to distance of the setting bar tail portion apart from cold bed head;Alignment distance correction refers to that practical bar stops
Position;The coefficient of friction that A, channel B can also be set calculates retro-speed according to coefficient of friction.Display data in picture
Mainly there is a physical location of two connected mechanical axis of motor of cold bed, the actual read number of two motor encoders and the reality of cold bed
The action cycle of speed, multiple lengths, cold bed.
In conclusion the basic principle for continuously running cold bed control method of the invention is: cold bed movable tooth is with each period
Corresponding speed tentatively guarantees the cycle of operation as tracking velocity, ensures that position is synchronous with the period by position correction twice, tool
The amendment opportunity of body is tentatively to correct first is that carrying out position in flying shear shearing, second is that carrying out essence to position in rotary drum movement
Really amendment, it is ensured that position of the cold bed movable tooth when connecing steel is synchronous with the period.
The technical problems to be solved by the invention include:
1) in the period for accurately controlling cold bed, it is made to meet the production of design most high speed;
2) position for accurately controlling cold bed, guarantees that it connects steel in situ.
It key problem in technology point of the invention and is intended to protect and a little includes:
1, the control of formula cold bed movable tooth variable period is continuously run
In multi-length shear optimizing shear, the multiple length of different length can be generated, this method is based on tracking multiple length information, different
Multiple lengths correspond to the different cold bed periods, this this period that turns cold continuously runs control mode, can satisfy various
The production of Optimal State.
2, the position correction of formula cold bed is continuously run
In cold bed movable tooth operational process, since the acceleration and deceleration motion of the fluctuation of drive apparatus, velocity variations can all generate
Certain location error.Based on position correction when continuously running formula cold bed movable tooth control method and accurately can control movable tooth and connect steel
Position.
