Embodiment 1

[0048] Embodiment 1: see figure 1 , a kind of method of quick calibration leveler zero position, described method comprises the following steps:

[0049] 1) Preparation of standard calibration backing plate;

[0050] 2) Accurately measure the actual value of the height from the installation bottom of each straightening roller box to the highest point of the roller;

[0051] 3) Find the deviation value between the actual value and the standard value of the height from the installation bottom of each straightening roller box to the highest point of the roller;

[0052] 4) Zero calibration;

[0053] 5) Zero correction.

[0054] Said step 1) preparation of the standard calibration backing plate, specifically as follows, respectively calculate the standard value h of the height from the mounting base of the upper straightening roller box to the highest point of the roller according to the design drawings 上 and the standard value h of the height from the installation base of the...

Abstract

The invention relates to a method for quickly calibrating the zero position of a straightener. The method comprises the following steps: 1) preparing a standard calibration base plate; 2) accurately measuring the actual value of the height from the mounting bottom of each straightening roller box to the highest point of a roller; 3) solving a deviation value between the actual value of the heightfrom the mounting bottom of each straightening roller box to the highest point of the roller and a standard value; 4) calibrating the zero position; and 5) correcting the zero position. According to the technical scheme, the problems that an existing straightener zero position calibration technology is inaccurate in precision, complex in calibration method and the like are mainly solved, the zeroposition calibration precision can be greatly improved through the scheme, and the calibration operation efficiency is improved.

Description

technical field [0001] The invention relates to a calibration method, in particular to a method for quickly calibrating the zero position of a straightening machine, and belongs to the technical field of cold-rolled steel rolling. Background technique [0002] The main function of the cold-rolled straightening machine is to straighten the parts with poor straightness at the head and tail of the incoming material, and to partially remove the scale on the surface of the head and tail of the incoming material. During operation, the upper roll of the leveler is inserted between the lower rolls to level the strip. The lower roller box composed of three lower rollers is integral, and the three upper rollers are respectively driven by three motors to realize the setting of different insertion amounts, and the insertion depth is monitored by the encoder on the motor. After the straightening roller is replaced by the straightening machine, it is necessary to carry out zero calibrati...
