On-line straightness measurement of round pipes and bars in real time and quality assurance with Zumbach BENDCHECK


W


hether diameter and ovality of steel bars and pipes are precise and within


the required tolerances, can already be measured and monitored during the production process. Measuring solutions integrated


in the production line supply all the data necessary for a correct quality


check. With the BENDCHECK system it is now possible to measure the straightness of the steel bar or pipe as well. Manual checks, complex calibration scenarios and high material losses are a thing of the past. Faulty production can be eliminated directly during ongoing production thanks to the non-contact, high


precision ODAC® laser gauges of the BENDCHECK system. BENDCHECK guarantees straightness by: • synchronous real time measuring with ODAC® laser scanners in the production process


• non-contact, high precision data sampling independent of


orientation


• direct integration in the production process according to customer specific requirements


• intuitive software for evaluation of high-speed data


• clear display with diameter, absolute bend value, bend angle as well as individual current measuring values


Customer specific system installation with 3 ODAC® 110XY laser measuring heads BENDCHECK measuring process


A minimum of 3 measuring heads are used to measure straightness. The product is normally transported on a rolling conveyor through the measuring station while the BENDCHECK system is recording the measured values along the entire piece length. The BENDCHECK system determines the bending of round products. It measures the position and diameter of the pipe at 3 different positions along the axis. BENDCHECK calculates the deviation of the position of the middle measuring head from the position of the two outer measuring heads. This value is then either divided by the distance or distance squared, the user can select the formula required to calculate the bend.
