Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail, it should be noted that the enforcement of the present invention be not limited to
Under embodiment.
See Fig. 1, measure the device of strip steel 11 sideslip, including WS side jig 1, DS side jig 2, control device 1,
Controlling device 2 13, WS side jig 1 is controlled by controlling device 1, and DS side jig 2 is controlled by controlling device 2 13,
Described control device 1 all includes hydraulic cylinder 3, displacement transducer 4, pressure transducer 5, electricity with controlling device 2 13
Magnetic reversal valve 8, electro-hydraulic proportional valve 9, check valve, hydraulic cylinder 3 outfan is connected with WS side jig 1 or DS side jig 2,
Hydraulic cylinder 3 is connected with check valve 1, check valve 27, and overflow valve 10 is arranged between check valve and hydraulic cylinder 3, pressure
Hydraulic cylinder 3 oil pressure measured by sensor 5, and the displacement of DS side jig 2 or WS side jig 1 measured by displacement transducer 4, electricity
Magnetic reversal valve 8, electro-hydraulic proportional valve 9 control check valve 1 and check valve 27.
Measure strip steel 11 sideslip method, milling train jig body is provided with milling train centre line marks, by WS side jig 1,
DS side jig 2 is close to milling train centrage respectively, it is assumed that its position stopped is M (mm) with the distance of milling train centrage,
So show value of displacement transducer 4 is M (mm), along with WS side jig 1 and DS side jig 2 is transported to both sides respectively
Dynamic, the value of displacement transducer 4 is increasing, until WS side jig 1 or DS side jig 2 maximum opening degree.
Under as-rolled condition, the width of strip steel 11 is the spacing of L, WS side jig 1 or DS side jig 2 and strip steel 11
For Y, the show value at the displacement transducer 4 of WS side, this position jig 1 or DS side jig 2 is S0=(Y+0.5L)；
This position is setting position.
The setting value of overflow valve 10 is the resistance that P0, P0 are more than in hydraulic cylinder 3 motor process, and strip steel 11 deviates in milling train
When the distance of heart line is more than Y, strip steel 11 can produce pressure to WS side jig 1 or DS side jig 2, when strip steel 11 is right
When the power of jig is more than P0, WS side jig 1 or DS side jig 2 retreats, it is assumed that WS side jig 1 or DS side
Displacement transducer 4 show value of jig 2 is S, W=S-S0It is strip steel 11 and deviates the numerical value of milling train centrage, W value
Display is on operation screen in real time；Operator, according to W value, adjusts the roll gap of milling train WS, DS side in real time, makes strip steel 11
Centrage returns to milling train approximate centerline.
In strip steel 11 operation of rolling, the control mode of jig is: as Y+0.5L≤S≤Y+0.5L+N, uses position control
Mode processed, namely makes WS side jig 1 or DS side jig 2 be positioned at setting position；As S ＞ Y+0.5L+N, adopt
With pressure controling mode, namely strip steel 11 is applied a constant pressure；In formula, S is the show value of displacement transducer 4,
N is departure, N=1～2mm, and the purpose arranging N is to avoid hydraulic cylinder 3 to vibrate near setting position.WS
Spacing Y=15 of side jig 1 or DS side jig 2 and strip steel 11～20mm, be set to 20mm, for all herein
The strip steel 11 of specification is all 20mm, say, that Y is definite value, and i.e. under as-rolled condition, strip steel 11 deviates rolling centerline
Maximum displacement be 20mm, for acceptable scope.Therefore strip steel 11 center is made when strip steel 11 through the adjustment of operator
When line returns to milling train approximate centerline, WS side jig 1 or DS side jig 2 automatically returns to position (the i.e. displacement biography of setting
Sensor 4 show value is S0=(Y+0.5L)), possess the state again detecting strip steel 11 sideslip.
The present invention controls WS side jig and the movement of DS side jig by hydraulic cylinder, it is to avoid jig and device damage, utilizes
Sensor provides moving parameter to provide foundation for adjusting work, and improves plate shape.
