BENDCHECK measures the straightness of round – pipes, bars and rods in real time


Whether diameter and ovality of steel rods, 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 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 product rotation
• 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

and offers
• easy calibration
• high service life
• low maintenance

Assure the quality of your steel pipes directly after the straightening process.

Measuring Process BENDCHECK

A minimum of 3 measuring heads are used to measure the straightness. In order to detect deviations in all directions, a product twist along the longitudinal axis during the measuring process (rolling process) is acceptable.

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 left and right 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.

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.
