Compared with prior art; The utility model milling train deviation-rectifying system detects the position signalling of steel band in real time; Through steel band displacement and preset value are compared, produce the steel band corrective control signal, and drive steel band towards a lateral movement that reduces the steel band position offset; Steel band is operated steadily, help guaranteeing product quality.
Description of drawings
Fig. 1 is the composition frame chart of the utility model milling train deviation-rectifying system.
The specific embodiment
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1, be a preferred embodiment of the utility model milling train deviation-rectifying system, it comprises left position sensor 1, parts such as right position sensor 2, controller 3 and driving mechanism 4 below describe respectively.
Left side position sensor 1, right position sensor 2 is configured in left side, the right side of steel band (scheme not shown) respectively, is used for detecting in real time and exporting the steel band position signalling.Certainly, position sensor also can be merely one, but precision is poor slightly.
Controller 3; Input connects the output 2 of left position sensor 1, right position sensor; Be used to receive the steel band position signalling; Calculate the steel band position offset and with pre-set threshold value relatively, output steel band corrective control signal when the steel band position offset exceeds pre-set threshold value, this steel band corrective control signal is a pwm signal.
Driving mechanism 4, the output of electrical connection controller 3 according to the action of steel band corrective control signal, drives steel band towards a lateral movement that reduces the steel band position offset.Driving mechanism 4 comprises servo valve 41, straight line actuation mechanism 42 and correction roller 43, and wherein: servo valve 41 is electrically connected the electric part of straight line actuation mechanism; Correction roller 43 is connected with straight line actuation mechanism 42.More excellent ground, correction roller 43 is provided with stepped edge, through this stepped edge steel band is revert to and requires the position.
In the present embodiment; After the left position sensor 1 of deviation-rectifying system, right position sensor 2 detect deviation signal; Feed back to servo valve 41 through controller 3; Servo valve 41 is through the straight line actuation mechanism, and the correction roller 43 in the control transmission system constantly moves, thereby steel band is moved in the centre of correction roller all the time.Steel band is operated steadily, help guaranteeing product quality.
Left position sensor 1 in the present embodiment, right position sensor 2 are photoelectric sensor, are preferably ccd image sensor; Controller 3 can be analog circuit or the digital circuit that comprises signal amplification module 31, calculation process module 32 and signal generating module 33, also can be made as a single-chip microcomputer simply; Servo valve 41 is a magnetic valve; Straight line actuation mechanism 42 is oil cylinder, cylinder or electric pushrod; Certainly also can select the other types parts.
What need explanation is that the detected deviation signal sensitivity of this deviation-rectifying system is higher, as long as the center that the steel band central point departs from roller slightly will produce deviation signal, thereby constantly controls the work of straight line actuation mechanism through servo valve.For the hydraulic linear actuation mechanism, hydraulic oil possibly cause oily variation and mechanical wear to increase at every moment in circulation, in case and servo valve stops up, just cause whole deviation-rectifying system cisco unity malfunction, make that the whole rolling operation is unreliable.This can solve with replacing hydraulic oil through constantly cleaning servo valve, but cost is very high, and efficient is relatively low.
To this situation, require the not high occasion of sensitivity to reduce deviation signal sensitivity a little in some correction according to the characteristics of the industry, have only when offset distance deviation signal output is just arranged during greater than preset value (like 2MM).The benefit that reduces the precision of detection signal is: (1) is improved the steel band operational reliability greatly, improves the steel band quality; (2) reduced maintenance cost; (3) mechanical wear of minimizing correction roller and hydraulic system; (4) uptime of raising whole system.In a concrete application system, through changing the precision of deviation signal, reduce the operating frequency of running part, thus the cleannes that prolong hydraulic oil, the operate as normal of assurance deviation-rectifying system, at least can prolong 1 year by original 3 months normal working hours.
Only be the preferred implementation of the utility model below, should be pointed out that above-mentioned preferred implementation should not be regarded as the restriction to the utility model, the protection domain of the utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in spirit that does not break away from the utility model and scope, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
