Problems solved by technology
[0004] The cold rolling mill is a large-scale equipment, and the relative distance between the double cone head coiler and the cold rolling mill is relatively far away, so compared with the original installation adjustment (that is, the initial installation of the cold rolling mill and the double cone head coiler) The first installation and commissioning, when the first installation, the cold rolling mill and the double cone coiler are new equipment, the equipment itself has high precision, you can choose a certain part of the cold rolling mill as a benchmark to compare the cold rolling mill and the double cone coiler One-time installation, so it is relatively easy), the readjustment, installation and adjustment of the double cone coiler become extremely difficult, and the cold rolling mill is a key equipment in the plate production line, if it is shut down for a long time to adjust and install , will have a negative impact on the scale of production and sales of the enterprise

Embodiment Construction
[0048] A method for installing and adjusting a double-cone coiler of a cold rolling mill, wherein the double-cone coiler includes two single-cone coilers, and the installation and adjustment method includes the following steps:
[0049] Step 1, such as figure 1 As shown, determine the position of the horizontal reference line for the installation of the double cone coiler. Because the double-cone coiler is located on the exit side of the rolling mill, its function is to coil the rolled strip into a coil with both ends flush, so its installation reference line should be determined based on the working roll of the cold rolling mill .
[0050] The steps are specifically:
[0051] Step 1.1, take the horizontal line perpendicular to the axis of the work roll 3 of the cold rolling mill (referred to as the axis of the work roll) as the horizontal reference line for the installation assistance of the double cone coiler, hereinafter referred to as the horizontal reference line;

Abstract
A method for installing and adjusting a double-cone coiler of a cold rolling mill, comprising a step of determining the position of a horizontal reference line for auxiliary installation of the double-cone coiler; a step of installing and adjusting the base flat iron of the double-cone coiler; Installation steps for the drive side coiler and installation steps for the operator side coiler. In the adjustment process, the present invention adopts multiple adjustment methods different from those of the prior art, which effectively improves the installation efficiency of the double-cone coiler and improves the installation and adjustment accuracy of the double-cone coiler. Great promotion and application value.
Description
technical field [0001] The invention relates to a method for installing and adjusting cold rolling equipment, in particular to a method for installing and adjusting a double-cone coiler of a cold rolling mill. Background technique [0002] In the working application of the cold rolling mill equipment, with the long-term operation of the equipment, the double-cone coiler (located on the exit side of the cold rolling mill, used for rolling The produced strip is coiled into a roll shape with both ends even), and problems such as loosening of the underground foundation will occur, resulting in excessive deviation of the coaxiality accuracy of the double-cone coiler. The symptoms are: coiling sheet There will be a series of problems such as abnormal sound and layer shifting in the material roll, which will seriously affect the product quality. [0003] When the deviation of the coaxiality of the double cone coiler is too large, it is necessary to break the foundation of the coil...
