Automatic detection apparatus for thin camber

Abstract

The invention discloses an automatic measuring device for a sheet camber, belonging to the curvature measuring field. The device comprises a measuring bench used for placing a steel plate to be measured; belts controlled by a stepping motor are parallelly arranged at the edge of one end of the measuring bench; the belts drive a height gage to move, and a probe of the height gage can move along the edge of the steel plate to be measured; the height gage is connected with a programmable logic controller (PLC) module, and the data obtained by the height gage by measurement can be stored in the PLC module. The measuring device improves the measurement efficiency of the sheet camber, and the measurement speed can reach 2 minutes per coil. The measuring device is connected with a display, and a resulting value and a curvature curve can be drawn and displayed on the display at any time in the measurement, thus leading the measuring result to be intuitive and distinct; production conditions and various parameters can also be pertinently adjusted in time according to the curvature curve drawn by the PLC in the production of the steel plate so as to direct the actual production.

Description

technical field [0001] The utility model relates to a curvature measuring device, in particular to an automatic detection device for camber of a thin plate. Background technique [0002] Steel plate camber, also known as edge curvature, represents the lateral curvature of the edge of the steel plate and is an important indicator for evaluating the quality of the steel plate. In the production process of the steel strip, due to the release of internal stress, the correction device and the adjustment of the disc shears, etc., the steel strip will have a camber phenomenon during the trimming process. [0003] However, the camber of the steel plate is very important to the performance of the steel plate. If the camber of the steel plate exceeds the specified standard, it will increase the loss of waste and defective products in the application. [0004] In view of this, all iron and steel production enterprises strictly control the camber of the steel plate. At the same time, t...

Problems solved by technology

[0006] The above method is limited by the measurement platform, the accuracy of the straight baffle and the measurement method, the usual measurement error is greater than 0.1mm / 1m; and the operation is inconvenient, the measurement results are greatly affected by the operating habits of different measurement personnel, it is difficult to guarantee the measurement accuracy; at the same time, due to the manual operation of the measurement, the measurement efficiency is very low, and it is difficult to meet the needs of a large number of measurements

[0007] On the other hand, in order to improve the production and processing level of the steel plate, improve the level of edge curvature control, and continuously effectively correct and improve the processing process, it is necessary to describe the shape of the edge curve during the measurement of the sickle bend of the steel plate, while the existing The detection methods and means cannot meet the above needs
