Embodiment
As shown in Figure 1, the utility model coil of strip internal diameter device for dynamically detecting is made of the displacement transducer 1 that uncoiler and is connected on the uncoiler, and uncoiler mainly is made up of mandrel 2, gear case 3, hydraulic cylinder 4, motor 5, turnover oil return line device 6, shifting axle 7.Wherein, mandrel 2 is made up of middle mandrel 8, fan-shaped block 9, and along with the move left and right fan-shaped block 9 of middle mandrel 8 rises and contract (1/6 relation), middle mandrel 8 is connected with hydraulic cylinder mandrel 10 by gear case 3, and hydraulic cylinder 4 is power resources of middle mandrel 8; Motor 5 is power resources of uncoiler rotation, and its connection gear case 3 drives mandrel 2, hydraulic cylinder 4 and shifting axle 7 rotations; The turnover oil return line of hydraulic cylinder 4, owing to hydraulic cylinder 4 rotates together with mandrel 2, and oil pipe can't rotate, so turnover oil return line device is the connector (turnover oil return line device 6 does not rotate) between hydraulic cylinder 4 and the oil pipe; Shifting axle 7 is connected an end of hydraulic cylinder mandrel 10, along with hydraulic cylinder mandrel 10 moves and moving and middle mandrel 8 is synchronous, is used to detect the harmomegathus state of mandrel 2.Mandrel 2 is sector structures, and it is made up of 4 secter pats 9 and middle mandrel 8, and middle mandrel 8 is 9 horizontal spreadings of secter pat when transmission side shrinks, the harmomegathus state of middle mandrel 8 move left and right reflection uncoiler mandrel 2, and its proportionate relationship is definite value (K=1/6).When the complete spreading of coil of strip and mandrel 2 was arranged on the uncoiler mandrel 2, mandrel 2 diameters were exactly the coil of strip internal diameter.Shifting axle 7 is installed on the uncoiler mandrel hydraulic cylinder body, be that 7 shift positions of shifting axle have been reflected the coil of strip internal diameter indirectly, utilize displacement transducer 1 to detect the displacement of shifting axle 7, with this displacement input PLC, convert the coil of strip internal diameter to through software and just can calculate residual strip length again.
As shown in Figure 2, the free end of shifting axle 7 is connected with a displacement transducer 1, this free end have three spacing: A is the mandrel position of rising entirely, is designated as+120mm, and this moment, the coil of strip internal diameter was 580mm; B is an interposition, is designated as 0; C is the full reduced position of mandrel, is designated as-120mm, and this moment, the coil of strip internal diameter was 473mm.As shown in Figure 3, displacement transducer 1 comprises a variable resistor 11 and a disposable plates 12, and this variable resistor 11 is connected with disposable plates 12, and by disposable plates 12 output shift quantity, disposable plates 12 connects an industrial computer 14 by one mould/number conversion plate 13.In the present embodiment, its model and parameter are as follows:
Displacement transducer model: KLW-300mm;
Operating voltage: 24VDC;
Output signal: ± 10V;
Precision: 0.1mm;
Displacement: ± 150mm 150mm ≈ 10v 0mm ≈ 0v-150mm ≈-10v;
Mould/number conversion plate model: 6ES7 334-0KE00-0AB0 (Siemens-S7) etc.;
Output signal: ± 27648 (≈ ± 10V);
PLC: Siemens-S7 etc.
As shown in Figure 4, the utility model mandrel displacement converts in the software program structure of coil of strip internal diameter, and inside diameter D and correlation parameter relational expression are as follows:
D＝K[(INPUT+27648)×(300÷55296)-30]+473；
The output valve of INPUT--mould/number conversion plate (telescopic shaft displacement numerical value);
The greatest measure of 27648--mould/number conversion plate output;
The harmomegathus ratio of K--telescopic shaft move left and right and uncoiler mandrel;
473--uncoiler mandrel minimum diameter;
55296---will ± 27648 convert to 0-55296 (27648+27648=55296 ,-27648+27648=0), its objective is and be convenient to calculate;
300--300 is displacement transducer range [150-(150)=300];
300/55296--converts corresponding displacement transducer shift length L=(INPUT+27648) * (300/55296) to;
The displacement transducer displacement of 30---uncoiler mandrel minimum diameter 473 correspondences (quite-120mm);
L--telescopic shaft displacement;
Δ L--L-30 telescopic shaft is from the displacement of starting point 473;
The diameter that Δ d--mandrel increases.
After calculating the coil of strip inside diameter D, just can be used for the accurate Calculation of residual strip length, guarantee the band steel location of entrance, whether inlet section strip steel location correctly depends on the residual strip length computation, and the coil of strip internal diameter is the part of length computation.
Residual strip length computation formula: L=(Л D
2/ 4-Л d
2/ 4)/H, wherein:
Current residual strip length on the L-uncoiler; The H-belt steel thickness; Л-3.14;
Actual coil of strip external diameter on the D-uncoiler; D-coil of strip internal diameter.
Automatically deceleration control is applied to be with steel to be positioned at and is with steel afterbody shearing location when entrance is typically whipping the most, when definite value is preset in the arrival of the residue length on the uncoiler, the positioning function of controller is activated, linear velocity is descended along certain curve by original travelling speed, arrives up to anchor point and sees diagram 5.Among the figure, S is total kilometres, and S1 is the distance to deceleration point, and S2 is the distance that decelerates to locating speed, and S3 is the distance of locating speed operation, and S4 is the distance of last location, S=S1+S2+S3+S4.When beginning to enter the promptly typical band steel of automatic deceleration control afterbody whipping, residual strip length L=S2+S3+S4 shears the location, so the precision of residual strip length computation directly influences the band steel location of postorder.
The whipping or the whipping phenomenon that lags in advance that adopt the utility model can avoid invar volume internal diameter varies and cause are avoided prolonging the production time and are escaped band, improve production capacity and product lumber recovery.Since its energy overall process detection of dynamic coil of strip internal diameter varies, and revise residue length in real time, and so can improve band steel location correctness greatly, the uncoiler detection and the residue length that can be applied to the metallurgical system production line are calculated.
