Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1, the present invention includes burr axle inner sleeve 1 and N number of annulus gear piece 2, arrangement fixed cover is in burr axle inner sleeve 1 in stairstepping for N number of annulus gear piece 2, and the diameter of each annulus gear piece 2 in burr axle inner sleeve 1 is even variation successively from middle part to both sides, in stairstepping.
The diameter of each annulus gear piece 2 evenly successively decreases successively from centre to bilateral symmetry ground, and be symmetric with in the middle of burr axle inner sleeve 1, middle largest diameter, the diameter of both sides is minimum.
The diameter being positioned at the middle annulus gear piece 2 of burr axle inner sleeve 1 is the diameter 9/10 of the annulus gear piece 2 being positioned at most edge, burr axle inner sleeve 1 both sides.Through actual tests, and consistent with theory calculate: theory calculate is that the worm that 200mm is high is pressed into the thick coiled material of 1mm, and its compression ratio is 1/200, when the worm amount sent to reduces 1/20, the coiled material be pressed into also correspondingly thinning 1/20, is 19/20 of original thickness 1mm, namely should be 0.95mm.And when the diameter of the gear piece of dual-side reduces 1/20 than original diameter, the coiled material be pressed into just eliminates thickness error 0.05mm.
Each annulus gear piece 2 width in burr axle inner sleeve 1 is all identical.
N is wherein 11,13,15,17,19, makes burr roller can be used for the burr roller of the various length such as 1.1m, 1.3m, 1.5m, 1.7m and 1.9m, and every segment length is 1m.The burr roller of 1.7m is produced corresponding to the soft graphite coiled material of 1.5m.
The N number of annulus gear piece 2 be enclosed within burr axle inner sleeve 1 carries out axial restraint by the screw of both sides.

As shown in Figure 2, the surface of the annulus gear piece 2 of burr roller of the present invention is equipped with longitudinal crown and teeth groove.
Width of the present invention is the process of a gradual change to central authorities and the thickness difference of breadths, because do not have the possibility of suddenling change.Therefore the diameter burr roller controlling feeding will being made central authorities reduces to side edge direction Bands is trapezoidal gradually.
Design principle of the present invention:
As shown in Fig. 7, Fig. 8, Fig. 9, according to lateral pressure effect: the graphite block of one piece of clay proterties is when there being roll pressed up and down, the graphite material of clay sense must squeeze in two directions to the left and right, and left and right graphite 12,14 also squeezes to the limit, left and right two of self inevitably, the pressure of certain top and bottom rolls be greater than left graphite 12, right graphite 14 to the resistance of middle graphite 13.But the resistance of this side direction exists, and be pass Delivery to the left and right sides decreasingly to open from centre, until in two outer side edges in left and right, its lateral compression power equals zero as extremely.Its graphite material is moved by mediad both sides similarly, but amount of movement turns around, is that being displaced sideways of central authorities is little, and the amount of movement of side wants large significantly, because lateral surface does not have graphite material, does not thus have resistance institute extremely.
Moreover roll is up upwards curved, under the decurved base of the roll of below adds and should ring, be greater than the thickness of its graphite coiled material outside two to the thickness making width to the graphite coiled material of Section Central, as shown in Figure 10.Figure 10 is the result of site test on the milling train of 1.5 meters of door fabric widths.The amplitude Section Central place of coiled material, namely the thickness at 750mm place differs 0.05mm with the thickness at both sides place, and stage casing is thicker than both sides.In an experiment, be highly 200mm by the worm below burr roller.The nominal thickness of the coiled material be pressed into through 7 breaker rolls is 1mm.Central authorities differ 0.05mm with the thickness on both sides.
Therefore the present invention is by change burr roller, produce different diameters, on amplitude direction, there is different thickness to change roll at width to there being different pressure to reach the graphite worm sent to, to reach the deflection reducing roll, making finally to produce the graphite coiled material product obtained up to standard.
The specific embodiment of the present invention:
As shown in figure 11, be the graphite linings that original feed is gone, if after existing burr roller starts rolling, roll, graphite linings 15 deform, and width is maximum to Section Central place pressurized, and central thickness is greater than the graphite coil thickness on breadths, as shown in figure 12.
If after burr roller of the present invention starts rolling, the graphite linings sending roll shop building to is concave, as shown in figure 13, then roll dual-side is stressed larger than original, and roll central authorities are stressed much smaller, the distortion of roll also can be little, and the width central authorities shutting out the graphite coiled material come are much smaller with the difference of breadths thickness.
The present invention can adopt 15 annulus gear pieces, that the print 15 pieces getting 100mm × 100mm on amplitude direction detects according to testing requirement, then burr roller should be divided into 15 sections, its diameter is reduced to two Bian Duan Bands ladder types gradually by central sections, reduces error to for the purpose of minimum to reach.The schematic diagram of burr roller as shown in Figure 1.
The concrete size of burr roller of the present invention can adjust according to the actual error situation of every platform coiled material production equipment.
Above-mentioned detailed description of the invention is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
