Method for on-line steel belt thickness detection by using steel belt damping device

Abstract

The invention discloses a method for on-line steel belt thickness detection by using a steel belt damping device. The method comprises: a steel belt in motion is clamped by using a compressing device and the part from an entrance steel belt segment to a clamped steel belt segment is kept to be in a static state; two pressure sensors that are arranged on an upper pressing block and a lower pressing block detect pressures applied on an upper surface and a lower surface of the clamped steel belt segment, and motion of a drive unit is stopped when the pressure values detected by the two pressure sensors reach a preset value; with a steel belt damping device, the entrance steel belt segment is guaranteed to be in a driving state all the time; and a thickness detection device carries out thickness detection on the clamped steel belt segment. According to the invention, on-line measurement of the steel belt thickness during the production process can be realized; data invoking can be carried out conveniently; and measurement work on the rolled steel belt becomes convenient.

Description

technical field [0001] The invention relates to the field of detection of steel strip thickness, and more specifically relates to a method for online detection of steel strip thickness by using a steel strip buffer device. Background technique [0002] Steel belt refers to the conveyor belt made of carbon steel. The steel belt can be used as the traction and movement construction of the belt conveyor, and it can also be used for bundling goods. A narrow and long steel plate required for mechanical or mechanical products. Steel strip, also known as strip steel, is generally supplied in coils, and has the advantages of high dimensional accuracy, good surface quality, convenience and processing, and material saving. At the same time, the steel strip can be directly rolled to form the basic structure of the shelf, and then spliced ​​into the entire shelf by bolts. .

AI Technical Summary

Problems solved by technology

[0003] In the basic construction of steel strip rolling shelves, the shelf factory generally obtains multiple coils of steel strips directly from the steel strip factory, and the thickness of the rolled steel strips is different. Therefore, the total length of two coils of steel strips of the same size is often due to the difference in thickness. They are also different. Often, the thickness of the steel strip will be greatly reduced if the thickness of the steel strip is increased a little. Since the purchase of the steel strip is usually priced by weighing, if the thickness of the steel strip is higher than the actual need, then the same price can be purchased. The length of the steel coil obtained cannot achieve the expected effect, resulting in low cost performance for purchase. Therefore, it is particularly necessary to detect the thickness of the steel strip before production.

Steel strips obtained from the manufacturer are generally packaged in bare packages. Due to transportation, loading and unloading, and storage, the outer surface is not suitable as a sample for inspection. Inspection methods can only be added during the production process to inspect the thickness of the steel strip; at the same time The storage limitations of the steel strip itself make it impossible to move at will. Therefore, it is very inconvenient to measure the thickness of the coiled steel strip in mass production.

[0004] At the same time, the surface of the coiled steel strip is not completely flat after unrolling, and the steel strip is often in a curved state, and the thickness of different positions of the same coiled steel strip is often not the same, so it is not convenient to directly detect ;The existing detection method is to manually open the rolled steel strip and then use a micrometer to measure one by one. The measurement is not only time-consuming and laborious, but also consumes a lot of manpower and material resources. At the same time, human factors are also a great factor that affects the measurement accuracy of the steel strip. The thickness of the steel strip may not be fully measured, but only deal with the thickness detection task of the steel strip according to one's own subjective assumptions, which has a great impact on the accuracy of the thickness detection of the steel strip

At the same time, during the whole process of steel strip thickness detection, the thickness detection data of the steel strip has been recorded manually, which is not only easy to make mistakes, but also difficult to carry out data classification and statistics, and the thickness data corresponding to the steel coil cannot be found when needed , has a great impact on production

[0005] When measuring the thickness of the existing steel strip, the steel strip must be kept in a static state, that is, it cannot be measured during the processing of the steel strip

However, the measurement of the thickness of the static steel strip is not very meaningful. In order to measure the thickness of multiple positions of the same steel strip, it is often necessary to manually pull the steel strip apart. The position is also only biased towards the initial section of the coiled steel strip
