Problems solved by technology

[0004] 1. The level gauge has high requirements for on-site vibration. The installation location of the level gauge is usually on the equipment. If there is vibration, the measurement accuracy will be greatly affected.
[0005] 2. The measurement accuracy of the straightening machine is required to be 0.1mm as the best, but the level instrument can not meet the accuracy requirements and can only reach 0.5mm
[0006] 3. The measurement accuracy of the level has a great relationship with the distance. The accuracy close to the level is higher than that at the far end, and the accuracy difference can reach 0.5mm

Embodiment 1

[0035] In this embodiment, calculate the corresponding values ​​of the outer circumference of the three major shafts of the rollers and the distance between the straightening rollers, make a corresponding table as shown in Table 1, and measure the outer circumference of the major shafts of the three rollers Finally, the distance between the straightening rollers can be obtained by checking the corresponding relationship table. In this embodiment, the corresponding values ​​of the outer winding circumference and the distance between the straightening rollers are first made into a ready-made table, and after measuring the outer winding circumferences of the three major shafts, the corresponding straightening roller distances are searched in the corresponding relationship table. The measured distance between the straightening rollers can be quickly obtained on site.

Embodiment 2

[0040] In this embodiment, the major axis of the pressing roller 1 and the major axis of the fixed roller 2 can be drawn in drawing software such as cad according to their size and position, and then the outer winding of the major axes of the three rollers can be measured by using the measuring function of the drawing software. The value of the circumference and the corresponding value of the distance between the straightening rollers.

Embodiment 3

[0042] In this embodiment, the length value marked on the tape measure is used as the corresponding outer winding circumference value, and the corresponding straightening roller shaft spacing value is marked at the corresponding outer winding circumference value, and the aforementioned tape measure is used to wind the three rollers to Measure the outer winding circumference of the three rollers on the outer circumference of the shaft, and mark the distance between the straightening rollers on the tape measure corresponding to the outer winding circumference as the actual measured distance between the straightening rollers. The tape measure of prior art is used for weighing length, therefore also can measure circumference, present embodiment uses the length position represented by tape measure as corresponding outer circumference circumference, for example tape measure 6353mm length position, promptly represents outer circumference circumference value 6352mm, mark the correspond...

Abstract

The invention discloses a method and tool of measuring distance between shafts for a straightening roller, and a manufacturing method of the tool, and specifically relates to a method of measuring distance between shafts for a straightening roller for the technical field of straightening. The method of measuring distance between shafts for a straightening roller includes the following steps: A, calculating the corresponding relationship between the outer circumference around the periphery of three large shafts of the roller and the vertical distance between a pressing roller and a fixed rolleraccording to the size and positional relationship between the large shaft of the pressing roller and the large shaft of the fixed roller; B, measuring the outer circumference of the three large shafts of the roller; and C, according to the corresponding relationship in the step A, obtaining a result that the vertical distance, between the pressing roller and the fixed roller, corresponding to theouter circumference measured in the step B, is the distance between shafts for the straightening roller. The method of measuring distance between shafts for a straightening roller can quickly measurethe distance between shafts for the straightening roller and can significantly improve the measurement accuracy for the distance between shafts for the straightening roller.

Description

technical field [0001] The invention belongs to the field of straightening technology, and in particular relates to the technology for measuring the distance between straightening rollers. Background technique [0002] After the straightening machine has been used for a period of time, due to factors such as wear, maintenance, and detection components, the parameters of the reduction amount of the straightening machine based on the large-axis reduction stroke will be inaccurate, thereby affecting the control of the straightening process. As the precision requirements for straightening steel are getting higher and higher, the errors caused by factors such as wear, maintenance, and detection components of the straightening machine to the straightening reduction can no longer meet the straightening precision requirements. The shaft position is verified to ensure the accuracy of the straightening reduction, and the verification process needs to accurately measure the distance be...
