Rolls include strip steel rolls, section steel rolls, wire rod rolls, billet rolls, rough rolls, finishing rolls, scale breaking rolls, perforated rolls, leveling rolls, steel rolls, cast iron rolls, cemented carbide rolls, ceramic rolls, etc., but no matter what type of rolls, the straightness measurement can be realized by the straightness measuring instrument, which is convenient to detect, comprehensive data, whether it is sampling, or full inspection, it is very convenient.
The off-line straightness measuring instrument adopts photoelectric measuring equipment, equipped with guide rail slide table, motor, etc., one-button fast and accurate measurement, realizes the detection of various information such as outer diameter, ovality, straightness per meter, overall straightness, warping head, warping tail, etc., and also analyzes and stores the collected information.
1) Bar diameter: 127 258mm;
2) Bar length: 600-1500mm;
3) Straightness measurement accuracy requirements: 03mm；
4) Diameter measurement accuracy requirements: 005mm；
1) The system is mainly composed of two parts: straightness measuring instrument and control system. Among them, the straightness measuring instrument is mainly composed of a position measuring instrument, a base, a linear guide rail, a transmission mechanism, a dut support, etc. The measuring instrument is connected to the control system through a power cord and data cable, and the power supply and disconnection, measurement, scanning movement and other actions of the measuring instrument are controlled by the control system.
2) The control system is mainly composed of control cabinet (including control and communication circuits), industrial computer, display, sound and light alarm, etc. The original measurement data of the measuring instrument is transmitted to the industrial computer in the control system for processing and calculation, and the calculation results are directly displayed on the display. The tolerance range of straightness, outer diameter and ovality can be set in the measurement software system, and when the measured value exceeds the set tolerance range, the system drives the sound and light alarm to sound and light alarm.
3) The base of the straightness measuring instrument is a thick steel plate welded structure or cast iron structure, and the overall stiffness is good; The guide rail adopts two linear guide rails; The transmission mechanism is driven by synchronous belts on both sides, which can avoid shaking caused by uneven force on both sides of the caliper. Therefore, the scanning motion of the caliper runs smoothly and there is no measurement error caused by mechanical mechanisms.
4) The scanning motion of the measuring instrument is controlled by the servo motor, and the distance data of the movement is transmitted to the measurement software system, and the system can correspond the measurement data to the distance data.
5) After the scanning of the measuring instrument is completed, the system calculates and displays the overall straightness error of the measured object and the straightness error at both ends.
6) The system can set the tolerance requirements, and after the measurement is completed, if the straightness error value exceeds the set tolerance range, the system will automatically sound and light alarm prompts. At the same time, the measurement software interface displays the out-of-tolerance position, straightness error value and bending direction, which is convenient for the operator to straighten according to the detection results.
