Abstract
The invention provides an accurate positioning method for conductive rollers of a horizontal plating bath, which is characterized by comprising the following steps: a, collocating a fixed measurement point, mounting measuring rods with the length L of +/- 0.01 millimeter in the centers of all connecting plates at the top of a stander, and adjusting the tops of all the measuring rods at the same elevation with the allowable error of +/- 0.01 millimeter after the stander is positioned; mounting measuring posts in the centers of the upper surfaces of bearing blocks of all conductive rollers and the positions corresponding to the measuring rods, wherein the distance between the upper surface of the measuring post and the center of the conductive roller is S +/- 0.02 millimeter; setting the distance between the lower surface of the measuring rod and the upper surface of the measuring post as H which is equal to Ho + 0.5 * (do-d); and b, during mounting the plating bath, when all the conductive rollers and the stander are accurately positioned, measuring the H values of all the conductive rollers by an inside micrometer, then working out the Ho values, and adjusting the conductive rollers by working out the H values through the formula when mounting the conductive rollers later every time. The method improves the positioning accuracy of the conductive rollers so that the transverse evenness of a band steel clad layer is good.
Description
Technical field:
The present invention relates to be with steel continuous electroplating technical field, particularly relate to the bearing accuracy of the conductive rollers of horizontal plating bath on the band steel continuously plating product line.
Background technology:
Have now on the band steel continuously plating product line that adopts horizontal electroplating bath, conductive rollers will remove after use for some time carries out the roll surface reconditioning, and then the use that resets.When resetting, how to control the bearing accuracy of conductive rollers well, be to influence the important factor that horizontal electroplating bath especially has the horizontal electroplating bath serviceability of fluid pressure clamping band steel ability.When conductive rollers was installed, available adjustment double-screw bolt 5 and nut were adjusted the position of conductive rollers bearing support, make the H value reach requirement, and as shown in Figure 1, the H value is the distance between web plate lower surface and the conductive rollers bearing support upper surface, the i.e. spacing of A face and B face.The measurement of H value, traditional method is to measure with Steel Ruler.When measuring with Steel Ruler, because the parallel misalignment of A face and B face, measurer's visual angle error and do not have influence of various factors such as fixed measuring point, even when measurer's attention is relatively concentrated, measuring accuracy also can only reach 1-2mm, this just makes that the conductive rollers bearing accuracy is poor, the placed in the middle property of band steel in coating bath is poor, and then makes that the strip coating transverse regularity is poor, thereby influences the serviceability and the quality product of coating bath.
Summary of the invention:
The purpose of this invention is to provide a kind of conductive rollers that can make and locate accurately, make that the placed in the middle property of band steel in coating bath is good and then improve the strip coating transverse regularity, improve the serviceability of coating bath and the conductive rollers of horizontal plating bath accurate positioning method of quality product.
The technical solution adopted for the present invention to solve the technical problems is: a kind of conductive rollers of horizontal plating bath accurate positioning method is provided, it is characterized in that: a, configuration fixed measurement point between thief rod and corresponding measurement column, get rid of A face and the parallel misalignment of B face and measurer's visual angle error, concrete grammar is all to install and measure bar in whole frame top web plate centers, the length of thief rod is L ± 0.01mm, all the thief rod top all is adjusted into same absolute altitude, permissible error ± 0.1mm behind the frame location; Upper surface center and the corresponding position of thief rod at whole conductive rollers bearing supports all install and measure post; Distance between measurement column upper surface and the conductive rollers center is S ± 0.02mm; If the spacing between thief rod lower surface and the measurement column upper surface is H, then H=H

oThe time numerical value; d
oBe the conductive rollers nominal diameter; D is the conductive rollers measured diameter, when plating tank is installed, behind whole conductive rollers and frame accurate location in the sixth of the twelve Earthly Branches, can at first measure the H value of all conductive rollers, utilizes above-mentioned formula to calculate H then
oValue is calculating H.After the value, when conductive rollers being installed later at every turn, can utilizing following formula to calculate H Zhi And and carry out the conductive rollers adjustment; B, replace Steel Ruler, improve the precision of measuring the H value with micrometer inside caliper; The A face is the lower surface of top web plate; The B face is the upper surface of conductive rollers bearing support.
The invention has the beneficial effects as follows: solved on the electro-galvanizing production line of horizontal coating bath, the normal problem that the transverse uniformity of plating difference that causes because of conductive rollers bearing accuracy difference occurs, once on certain production line, adopted the technology of the present invention to carry out the installation location test of conductive rollers, test-results shows, after adopting the technology of the present invention, no longer occur because of conductive rollers bearing accuracy difference produces the problem of transverse uniformity of plating difference, thereby improved the serviceability and the quality product of coating bath.
