Description
The present invention relates to the measurement mechanism in the gap between two rolls of measuring tool bulk measurement of a usefulness or the roller, for the adjustment of this measuring tool body between two rolls or roller, three surperficial contacted supporting rollerns with one of roll or roller are housed at least on one side of measuring tool body, wherein two are positioned at the both sides of measured gap and are symmetrical in the plane, gap, the another side of measuring tool body be equipped with at least two with second roll or the contacted supporting rollern of roller surface, the contact point of they and second roll or roller surface is symmetrical in the plane, gap, it is but that breaker roll or roller surface are synchronized with the movement and press to this surface that roll or roller have two supporting rollerns that are symmetrical in the plane, gap at least, two measuring gages of radially installing relatively are housed on the measuring tool body, movable in the symmetrical plane of its gauge head between both sides, plane, gap, roll or roller surface contact with supporting rollern, just in the plane, gap against roll or roller surface activity.The present invention also relates to the method for this measurement.
In a kind of known measurement mechanism (DE-A1 752 947), the axle of supporting rollern is parallel to the axle of the roll that constitutes measured gap, and these rollers are contained in the turning rolls, and press to the surface of tested roll.Distance between the turning rolls of both sides, plane, gap, as the gap width of measuring between the roll, this distance is used for the calculated gap value under the situation of known roll diameter.
Therefore, with this known measurement mechanism is not measurement clearance itself, but the distance between the measurement turning rolls, this has just produced a shortcoming: the geometric properties of measurement mechanism and roll must be considered in the measurement result and go, like this, measurement mechanism each in addition the tolerance of part and roll also entered measurement result thereupon.When roller diameter was very big, turning rolls was subjected to a kind of very strong chock effect, makes measurement result be subjected to the influence that turning rolls is pressed against the power of roller surface.
The another one shortcoming of this known measurement mechanism, what be that its measures is the roll bus that is positioned at outside the plane, gap, like this, roll shape enters measurement result and makes it unfounded with the deviation between the desirable geometric configuration.
The measurement mechanism of the sort of style of describing during beginning is disclosed by German patent specification DE-B2639240.Though this measurement mechanism is measured just in time is in the plane, gap that is is the gap between two rolls or the roller in by the plane of two opposed rolls or roller axis, the motion of supporting rollern and the motion of gauge head link, therefore, make measurement result be subjected to the influence that supporting rollern is added in the snap-in force on tested roll or the roller.
The another one shortcoming of this known measurement mechanism is that measuring process is always carried out the same position on tested roll or roller length.In order accurately to measure the gap width on the whole length, must from the gap, take out this measurement mechanism, roll or roller axially on reload in the gap after moving the position and go.This is a trouble and time-consuming, and, if roll or roller are not accurately to fix on same position in twice continuous measurement, will cause measurement result inaccurate, especially all the more so when the xsect of roll or roller departs from circle.
And, as everyone knows, milling train cold or heat for the metal roll, the variation of its roll seam occurs in and is subjected to mechanical wear, refaces, hot-fluid enters roller surface and roll when the influencing of gravity, an available complicated mathematical model covers these and changes, and takes corresponding correction measure under situation about not measuring.In addition, the true shape that total grasp does not live the gap is always disadvantageous, and the numerical value of being calculated is accurate inadequately to effective correction.
The objective of the invention is for avoiding these shortcomings and difficulty, and create a kind of measurement mechanism and method that starts described style, with accurate measurement clearance value with measure roll in the plane, gap or the surface configuration of roller, can avoid the reason that makes measurement result unfounded with this apparatus and method.Particularly the gap can be measured with simple method on its total length, the influence of the snap-in force of not supported pair of rollers roll of its measurement result or roller surface.
This task is to solve like this according to the present invention: the axle of supporting rollern is perpendicular to the axis of roll or roller, but and rotation be installed on the measuring tool body.
As wanting this device automatically to measure on the whole length in gap, especially to broad strip mill, it preferably has two drivable supporting rollerns at least.
Realize that by means of a cogwheel gearing swing of supporting rollern axle in the measuring tool body guarantees being synchronized with the movement of supporting rollern suitably.
Stability outstanding, be particularly suitable for the most preferred embodiment that broad strip mill is used, it is characterized in that on the measuring tool body, having adorned 8 supporting rollerns, 4 surfaces that device leaned against a roll or roller wherein, and the axle of two supporting rollerns that the measuring tool body axis radially is oppositely arranged is rigidly connected mutually, and they can be around the measuring tool body axis swing that is parallel to roll or roller axis.
In order to obtain point-device measurement result immediately after the milling train single hot-roll, this measurement mechanism has preferably been installed a temperature sensor, and it is suitable being contained in this temperature sensor on the close position of a measuring gage.
A method of measuring the gap between two rolls or the roller is characterised in that, this measurement mechanism is put into go in gap and fix the center after, move in this gap, length direction upper edge of roll or roller by means of supporting rollern, measure gap width continuously, and meanwhile measure the surface temperature of roll or roller.
Occur irregularly as roll circumference surface, just help measuring, because can rotate roll one by one or special angle of roller carries out duplicate measurements to the gap with this measuring method.
Accompanying drawing by means of an embodiment is elaborated to invention below.Fig. 1 is the side view of a width belt steel hot-rolleding machine frame, and Fig. 2 is the front view of this measurement mechanism, and Fig. 3 is the cut-open view along the III among Fig. 2-III line.
In the width belt steel hot-rolleding machine frame that Fig. 1 drew, a gap 2 for adjusting has specific width 3 is installed with top roll 4 and lower roll 5 versatilely in frame 1, be bearing in respectively on the backing roll 6.This gap 2 to be measured constitutes a plane, gap 7 by the axis 8,9 of upper and lower roll.
Shown in Figure 3, measurement mechanism 10 has a hollow measuring tool body 11 to constitute a housing.Respectively being equipped with two in the front end 12 of measuring tool body 11 and rear end 13 can be around the sustained ring 15 of longitudinal axis 14 swings of measuring tool body 11, and they are that flange 16 by sustained ring 15 upper edge measuring tool bodies 11 longitudinal axis 14 directions is contained on the measuring tool body 11 by sliding bearing 17.The rotation of two sustained rings 15 of the every end 12,13 of measuring tool body is couplings like this, and promptly a sustained ring 15 causes promptly that to angle of a direction rotation adjacent sustained ring 15 rotates an identical angle in the opposite direction.This is by two rotatable shafts of installing along measuring tool body longitudinal axis 14 directions 18 in the measuring tool body, 19 reach, axle 18,19 intermesh by gear 20, one in the adjacent sustained ring 15 is passed through gear 21 and axle 18 couplings, and the sustained ring 15 of its adjacency passes through gear 21 and second axle 19 coupling equally.
The coupling of sustained ring by measuring tool body 11 1 ends 12 and second sustained ring of the other end 13, the rotation of a sustained ring 15 not only causes the backward rotation that is adjacent sustained ring 15, and cause on measuring tool body 11 other ends 13 corresponding sustained ring 15 rotation and with the backward rotation of the adjacent sustained ring 15 of the latter.One of diaxon and drive unit 22 engagements, drive unit is installed on the end face of measuring tool body 11.
Two are approximately perpendicular to measuring tool body 11 longitudinal axis 14 and axle 23 in line is fixed on each sustained ring, and its free end is equipped with rotating supporting rollern 24, and they are measuring tool body 11 centering supporting usefulness.Measuring tool body 11 is exactly that eight supporting rollerns have been installed by this way, leads in roll seam 2 and feels relieved usefulness as it.In the supporting rollern 24 on per four surfaces 25,26 that lean against one of roll 4,5.Sustained ring 15 and supporting rollern 24 will act on the axle 18,19 and like this action is pressed on the outside surface 25 and 26 of two rolls staggered relatively 4,5 supporting rollern 24 by drive unit 22.Because the measuring tool body is so automatically aimed in gap 2, so its longitudinal axis 14 is parallel to the axis 8,9 of roll 4,5, and is positioned at the plane, gap 7 that is positioned by axis 8,9.
Greatly about the centre of the longitudinal length of measuring tool body 11 and the sustained ring at two ends between, measuring gage 27,28 is installed on two opposite faces of measuring tool body 11, its gauge head 29 is to move along the axis 30 of measuring gage 27,28, and the effect that preferably utilizes spring with gauge head to external pressure.Measuring gage 27,28 is to arrange that like this their axis that is aligned to straight line 30 is arranged in the symmetrical plane 31 by supporting rollern 24 longitudinal axis 14 of measuring tool body 11, the opposite face activity in measuring tool body 11.Near measuring gage 27 temperature sensor 32 has been installed.
The numerical value of being noted from measuring gage 27,28 and temperature sensor 32 goes by means of the lead that comes or be sent in the data processing equipment by means of radio signal of not drawing.
The function of this device is as follows:
Measure by pack in gap 2 the gap 2 between 10 pairs of upper and lower rolls 4,5 of measurement mechanism or the surface configuration of roll 4,5 at interval in a period of time, for this purpose, open greatly sometimes a little in gap 2, remains unchanged again when enough wide.Measurement mechanism can be packed between the roll from end face, and for this purpose, frame 1 has an opening herein, and the time spent can not be placed in this opening measurement mechanism.Also the axle 23 of band supporting rollern 24 can be swung to toward each other in addition makes measurement mechanism put into roll seam 2 from rolling direction.
Because drive unit 22 makes axle 23 thereby make supporting rollern 24 move relative to one another and rely on the surface 25,26 of roll 4,5, measuring tool body 11 is accurately harmonized in roll seam 2, makes the axle 30 of two measuring gages always be arranged in plane, gap 7.When measuring the roll seam with measuring gage 27,28, when measuring the temperature of roller surfaces 25 or 26 with usefulness temperature sensor 32, drive supporting rollern 24 guiding measuring tool bodies 11 with motor 33 and 2 move along the gap, motor 33 is to mesh with the annular wheel 35 of a pinion wheel 34 with supporting rollern.
By means of every roller bus of being close to of measuring gage contact, can accurately detect the actual profile shape of roller surface 25,26.Measurement is directly carried out, and promptly is the intermediary that does not make measurement result unfounded.Because measuring tool body 11 is by means of the guiding of supporting rollern 24, the local error in gap 2 is roller surface 25 or 26 local error in other words, only by measuring with these surface 25 or 26 measuring gages that cooperate 27 or 28.Owing to lean against being driven of two supporting rollerns 24 on the bottom roll 5, make that measurement mechanism can come very accurately as the crow flies, travelling backwards is moved.Little and its center of gravity of measuring tool body 11 quality is low also to be additional advantage, and this helps straight accurately moving.Because the motion of supporting rollern 24 and the motion of gauge head 29 are irrelevant, so the not influence of the snap-in force of supported roller of measurement result, this just makes the snap-in force of these accurate adjustment measuring tool body 11 usefulness can select very highly.
As long as, also can find out local polishing error with measuring again after angle of two rolls, 4,5 rotations.The measurement of the roller surface temperature of carrying out simultaneously with measurement clearance makes and might carry out the temperature correction to the profile in tested roll or gap.
The embodiment that the present invention is not restricted among the figure to be described, but can change in many aspects.In order to give the measuring tool body 11 guiding, might not need 8 supporting rollerns 24, promptly need 4 on each roller surface, and 3 also enough at 26,2 roller surfaces 25 over there of roller surface.In this case, measuring tool body 11 is supported by the tripod of a frame on bottom roll 5.
Measurement mechanism is not to be equipped with driving, and it also can be by means of one between roll 4 and 5 rope or a rod and be pulled or promote.In addition, temperature sensor 32 not necessarily is critical and installs by a measurement calliper 27,28, and it also can be installed near a supporting rollern 24.
