On-line Quality Assurance Zumbach’s Bendcheck measures the straightness of round pipes and rods in real time
laser measuring heads
W
hether diameter and ovality of steel rods 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 for straightness.
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 oscillations
• direct integration in the production process according to
• intuitive software for evaluation of high-speed data
• clear display with diameter, absolute bend value, bend angle

The bending of the product is continuously shown on a graph on the display panel. A mini-statistic also shows the 5 maximum bend values in the product currently being measured

as well as individual current measuring values
Assure the quality of your steel pipes directly after the straightening process.
Bendcheck measuring process A minimum of 3 measuring heads are used to measure straightness.
The product is normally rotated along the longitudinal axis during the measuring process to detect all deviations in all directions (rolling process).
The Bendcheck system
determines the bending of round products. It measures the position and diameter of the pipe at 3
Bendcheck calculates the deviation of the position of the middle measuring head from the position of the right measuring head. This value is then either divided by the distance or distance squared, the user can select the formula required to calculate the bend.
