Description
Technical field
The invention belongs to metallurgical machinery equipment automatic measurement, tester technical field, is the checkout gear of a kind of online automatic detection cold-strip glacing flatness (plate shape).Be suitable for the online detection of various cold-strip glacing flatness.
Background technology
Along with people to improving constantly that strip shape quality requires, testing technique for shape of strip more and more is subjected to extensively paying attention to both at home and abroad.It is a very difficult problem that yet plate shape is detected, and is that disturbing factor is many because testing environment is abominable on the one hand; Also be because flatness defect has the form of expression of multiple complexity on the other hand.It is the prerequisite and the key of the control of plate shape that plate shape is detected.Because industrial the pressing for strip material plate shape of cold-rolled plate and strip improved the great economic benefit of being brought, the research that makes testing technique for shape of strip still is an important topic of current board rolling technical elements.For many years, the research work that plate shape is detected is carried out very actively, and people constantly seek new detection principle and detection method, develops the plate profile instrument that satisfies the industrial production needs.The research work of domestic plate profile instrument is since the beginning of the eighties in last century, but homemade plate profile instrument that can operation steady in a long-term in industrial production still belongs to blank at present.Since the sixties in last century, drop into the development that considerable man power and material carries out detecting instrument of flatness abroad.Although developed at present both at home and abroad the plate profile instrument of many forms, successful Application having only in the production practices is several.As seen, develop high-precision plate shape measurement sensor, seek reasonable test method, it is very crucial and important to improving strip shape quality to develop high-quality plate profile instrument.
Plate shape is detected and is divided into contact and contactless two kinds of forms.It is simple relatively that contactless plate profile instrument has structure, and sensor is nonrotational element, and is easy for installation, do not have friction with strip surface, can not scratch advantages such as band.But it has many drawbacks, and plate shape signal is non-direct signal, and signal is handled easy distortion, and is subject to the influence of many factors such as thickness of slab fluctuation, variations in temperature, vibration.Therefore, the contact plate profile instrument obtains paying attention to more widely and certain application in cold-strip plate shape context of detection.
Use the air bearing formula plate profile instrument of segmented measuring roll plate profile instrument that maximum contact detecting instrument of flatness is Sweden ABB AB (being called for short the segmented plate profile instrument) and Britain DAVY company at present.The core parts of these plate profile instruments all are plate-shaped sensing rollers.
Segmented plate profile instrument measuring roll is made up of roll body, pressure sensor, collars.Collars is that its thickness is generally less than 10mm, adopts hot charging between collars and the roll body through the steel loop that quenches, so that certain precompression is arranged, by collars the tension force of band is passed to pressure head.This segmented measuring roll in use, even the machining accuracy of measuring roll is very high, owing to variation of temperature causes the reasons such as variation that pressure changes, the variation of mill speed causes frictional force between band and the measuring roll of giving between collars and the roll body, collars is produced relative rotation with respect to roll body, make the rough of measuring roll and the scuffing band.Because the structure of this measuring roll causes this stubborn problem to be difficult to solve.In addition, the grinding roller process before the dress collars is an intermittent grinding, the grinding roller difficult quality guarantee; Because it is consistent that the grinding of collars internal diameter is difficult to reach, and therefore be difficult to guarantee that collars is consistent with the precompression between the roll body, and precompression can't be adjusted.
The center of air bearing formula plate profile instrument measuring roll is an axle, and roller shell is being overlapped in the outside.Leave certain interval between axle and axle sleeve, fill in the gap with pressure-air, strap tension changes and causes that the gap changes, and the pressure of gas is changed, and detects the tension distribution of band with this.But this plate profile instrument is very harsh to the requirement of working environment, needs clean especially air, the cisco unity malfunction otherwise the air duct of measuring roll is easily blocked.Thereby the application of this plate profile instrument is very restricted.
Summary of the invention
The object of the present invention is to provide a kind of burst endoporus piezomagnetic plate profile instrument of online automatic detection cold-strip plate shape.That this plate profile instrument has is rational in infrastructure, signal stabilization, accuracy of detection height, antijamming capability are strong, long service life, be easy to installation and maintenance and advantage such as applied widely.Has important practical value to improving rolled strip strip shape quality and lumber recovery.
This burst endoporus piezomagnetic plate profile instrument is made up of measuring roll, bearing block, collecting ring, phase-sensitive detector, low-pass filter amplifier, peak-holding circuit, data acquisition board, computer and display, it is characterized in that: adopt the interference fit form that 5-40 independently roller sheet is installed on the hollow core shaft of described measuring roll, the end cap at all roller sheets and roll body two ends connects firmly by 4-6 the bolt of having strong market potential is in the same place, and each roller sheet is an independently plate shape detecting unit; Each roller sheet is made up of lamellar body, piezomagnetic load cell and self-locking adjusting pad, and two or four piezomagnetic load cells are installed in the cavity of lamellar body circumference symmetric position, with the self-locking adjusting pad lamellar body and piezomagnetic sensor is fixed as one.Simultaneously, utilize the minimum gradient of self-locking adjusting pad accurately to adjust the precompression of piezomagnetic sensor.This structure is different from other contact plate profile instrument, and it does not have collars, does not therefore have the sliding problem between collars and mandrel.Thereby fundamentally solved the circumferential sliding problem of the collars that causes owing to reasons such as variations in temperature, frictional force.Scuffing phenomenon to band can not appear in the course of the work.
This burst endoporus piezomagnetic plate profile instrument utilizes the flange of current-collecting device directly current-collecting device to be fixed on the measuring roll bearing block end face, and compact conformation vibrates little.The brush holder of current-collecting device has adopted beryllium-bronze material, and geometry design is reasonable, make between brush and the slip ring to contact pressure constant substantially all the time, guaranteed the good communication of signal.
This burst endoporus piezomagnetic plate profile instrument is handled at a signal each road plate shape signal has been adopted peak-holding circuit, makes computer particularly simple, convenient to its data acquisition, helps improving the acquisition precision of signal.
