On-line testing of rolled wire or rods in steel mill production lines is important in quality management. This on-line detection device is indispensable not only for measuring the outer diameter, but also for continuously measuring the corresponding cross-sectional profile size, thereby grasping the product features and controlling the production equipment and higher-level applications with various data output in real time.
In order to meet the rolling demand of round steel, the bar caliper adopts non-contact measurement method to realize online real-time automatic high-speed detection. The omnidirectional outer diameter inspection is performed with an eight-axis probe, and the diameter, ellipse, average, and cross-sectional profiles in eight directions are obtained through data processing and analysis. It can realize the display and statistical processing of the out-of-tolerance alarm and data, and can be connected with the host computer.
In order to achieve high-precision measurement, the bar caliper can be automatically calibrated to ensure long-term operation accuracy. It has an over-temperature alarm function, which can detect device abnormalities in time, has a heat-proof and waterproof protective layer, and is blown by a high-pressure blower. The effects of the iron sheet have been fully implemented.
The bar caliper is a high-precision outer diameter inspection device that uses high-brightness light source, electronic shutter technology, and multi-channel synchronization technology to eliminate jitter errors. The bar caliper has no analog processing and mechanical moving parts. In principle, there is no precision drift, and the detection of the eight sets of probes does not interfere with each other, which makes even if one or several groups are damaged. Affects the measurement of other probes. The measuring accuracy of the bar caliper can reach 0.02mm.
The bar caliper uses a linear array CCD as a sensor, and the object side is a telecentric parallel light source. The detecting device has no mechanical moving parts, and its life is semi-permanent. High-speed measurement is possible, and the measurement frequency of each set of probes can reach 500Hz/1000Hz.
Bar caliper can measure diameter, ellipticity and cross-section profile, radial measurement without blind zone, timely and accurately reflect the dimensional change of the measured rolling stock, and can produce various common defects (ear, wrong roller) Etc.) to perform the test, to perform statistical and analysis on the measured data, to perform real-time communication with the production system computer, to measure the data transmission, and to have a correction function.
Bar caliper professionally developed software system, operation interface (priority Chinese interface):
Screen display: numbers, sections, measurement curves;
Statistics and analysis: measurement, statistical analysis;
Query: Process the data obtained from the measurement unit, save the measurement data, and query at any time. The storage time is more than one year.
In addition to the software itself has the storage and analysis functions of the measurement data, the software also provides an external database, which is convenient for the user to process, sort, analyze, calculate, and count the measurement data according to his own needs.
Conclusion
The bar caliper can display the information required for the measurement in detail, and can detect some basic defects such as wrong rollers and ears. The use of bar calipers is a high-precision on-line inspection device that brings great convenience to improve quality and speed up production.
