Description
Technical field
The utility model relates to a kind of template instrument, particularly relates to a kind of contactless template instrument.
Background technology
Template signal is an important parameter in steel rolling production process, and accurately measuring and controlling is the sole mode that improves product strip shape quality.Traditional template measuring instrument, is by being integrated in the pressure sensor in slewing rollers, detects tension force distribution condition with steel broad ways and detects template.Along with the day by day raising of market to strip surface quality requirement; contact type measurement roller exposes increasing shortcoming; in particular for the damage of solution measuring roller to belt steel surface; the method of employing chromium plating or rubber-coated/other material on roller; make investment and maintenance cost too high; user needs regular update protective layer; staking-out work specification requirement is complicated; after pressure sensor failure, must send the shortcomings such as manufactory's repairing back to, make traditional template measuring roller cannot meet the requirement of Vehicles Collected from Market keen competition.
Utility model content
The purpose of this utility model, is to provide a kind of template instrument of contactless automatic measurement steel rolling production process template signal.
The technical solution of the utility model is as follows:
A kind of contactless template instrument, described template instrument comprises template measuring system, template measured deviation system and template control system, it is characterized in that: described template instrument also comprises a signal transmission unit, described signal transmission unit comprises measuring transducer, encoder and signal transmission passage, described measuring transducer is positioned at the below of roll line, detection is by the Oscillation Amplitude of measuring tape steel, and detection signal is transferred to template measuring system by signal transmission passage;
Described encoder is connected with template control system, detects speed and the rotation direction of eccentric roller.
Further, in such scheme, described measuring transducer is row's non-contact turbulent flow sensor.
In such scheme, described template measured deviation system comprises a frequency conversion fan, described template measured deviation system is connected with template control system, described template control system is according to the duty of the speed of the eccentric roller detecting and rotation direction judgement eccentric roller, and by this transfer of data to template measured deviation system, template measured deviation system is controlled the operating frequency of frequency conversion fan, controls by the vibration frequency of measuring tape steel.
The beneficial effects of the utility model are as follows:
1, the glacing flatness of the utility model under can real-time online detection cold rolled sheet belt tension state, can adjust timely the roller, inclination of roll, the working method such as traversing, the roll surface spray cooling system that coupling system carries, can greatly improve the product quality of cold rolled sheet.
2, seismic degree of the present utility model is high, strong interference immunity, and accuracy is high.
Accompanying drawing explanation
Fig. 1 is system frame structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
The utility model is the amplitude with steel each region of broad ways under a certain air effect power by measurement, the tension distribution of analytic band steel broad ways, thus detect the template value with steel.A kind of contactless template instrument of the utility model, described template instrument comprises template measuring system, template deviation-rectifying system and template control system, template measuring system is wherein mainly that the template parameter with steel is rolled in real-time on-line measurement, template deviation-rectifying system is the parameter of real-time controlled rolling operation, and template control system mainly realizes the detection to the speed of eccentric roller and rotation direction.Inventive point of the present utility model is: this template instrument also comprises a signal transmission unit, this signal transmission unit comprises measuring transducer, encoder and signal transmission passage, wherein measuring transducer is positioned at the below of roll line, real-time detection is by the Oscillation Amplitude of measuring tape steel, and detection signal is transferred to template measuring system by signal transmission passage; Encoder is connected with template control system, detects speed and the rotation direction of eccentric roller.
In the utility model, the measuring transducer in signal transmission unit is row's non-contact turbulent flow sensor.This kind of non-contact turbulent flow sensor certainty of measurement is high, and strong interference immunity is applicable to the accurate control with steel plate type parameter.
The utility model deviation-rectifying system comprises a frequency conversion fan, described template measured deviation system is connected with template control system, described template control system is according to the duty of the speed of the eccentric roller detecting and rotation direction judgement eccentric roller, and by this transfer of data to template measured deviation system, template measured deviation system is controlled the operating frequency of frequency conversion fan, controls by the vibration frequency of measuring tape steel.
The above-mentioned specific embodiment of the present utility model is just to the illustrating of the utility model patented technology scheme, and do not form the restriction to the utility model protection domain.The improvement of the technical scheme that any invention according to the utility model spirit produces, conversion, omission, substitute etc., all belong to protection domain of the present utility model.
