Embodiment Construction

[0023] The present invention is described in further detail now in conjunction with accompanying drawing.

[0024] Such as Figure 2-4 , a step pad position calibration device on a rolling mill, including a calibration block 2, the number of calibration blocks 2 is 2, each calibration block 2 is provided with an "L" shaped handle 1, and between the "L" shaped handles 1 is provided The retractable anti-off connecting rod 4, insert the positioning pin 5 in the middle of the anti-off connecting rod 4, the distance between the calibration blocks 2 will not change, and prevent the calibration blocks 2 from falling off; when the calibration block 2 is not in use, pull out the positioning pin 5. The two calibration blocks can be stored separately. The single calibration block 2 is a cuboid structure, the roughness of the processed surface is Ra6.3, and the length is the dimension between the outer side of the moving frame 7 and the inner side of the "L"-shaped fixed frame 3 when the...

Abstract

The invention discloses a device and a method for calibrating the position of a stepped pad on a rolling mill, which are used for calibrating the working position of the stepped pad on the rolling mill. The calibration device is provided with a first calibration area and a second calibration area which are symmetrical to each other, the first calibration area is provided with an L-shaped handle, a first end of the L-shaped handle is provided with a calibration block, a second end of the L-shaped handle is provided with a handheld ring, the L-shaped handle is provided with an anti-falling connecting rod, and the anti-falling connecting rod of the first calibration area and the anti-falling connecting rod of the second calibration area are fixed through a positioning pin; the upper step base plate adjusting part is provided with an L-shaped fixed frame, a driving hydraulic cylinder and a movable frame which are mounted on the rolling mill, and a calibration device is mounted between the driving hydraulic cylinder and the movable frame; the step pad position is calibrated, the problems that calibration and verification of the step pad position on a hot rolling and finishing mill group are difficult, long in time, inaccurate and the like are effectively solved, the calibration precision can be within 1 mm, and the situation that due to inaccurate calibration of the step pad position, the roller replacement time is prolonged, and production is affected is reduced.

Description

technical field [0001] The invention belongs to the technical field of position positioning of step pads, and in particular relates to a device and method for calibrating the position of step pads on a rolling mill. Background technique [0002] The pressing system of the F1-F7 finishing mill unit of the hot rolling line is mainly composed of the upper stepped backing plate, HGC hydraulic cylinder 15, upper and lower support rolls, upper and lower work rolls, etc. The support rolls and work rolls are periodically ground and then used on the machine , in order to compensate for the changes in the gradual reduction of the roll diameter after multiple grindings, each rolling mill is equipped with an upper-step backing plate thickness adjustment device. [0003] The upper step pad thickness adjustment device is composed of a driving hydraulic cylinder 6 with a displacement sensor, an "L"-shaped fixed frame 3, a moving frame 7, and a step pad (8-10), etc., such as figure 1 shown...
