rib measurement system

Optical geometry measurement systems for reinforcing steel

The devices are used for automated geometric measurement in quality assurance and factory testing of hot and cold rolled reinforcing steel with two, three, four or six rows of ribs.Both high-grip and intended material can be measured.The measurement is carried out according to standards according to German, European and most international standards.
For the measurement, the samples must have a length of between 200 and 500 mm.The test bar is clamped horizontally in a three-jaw chuck and, depending on the measured variable, illuminated with high-contrast or transmitted light. The test object is optically captured from different angles by two to three high-resolution CMOS black and white cameras and displayed in a window on the computer monitor
A computer and an image processing unit digitize the respective image. The measuring principle is based on the search of black and white transitions, where the object boundaries are determined by means of a gradient method from the gray levels.

The instrument is calibrated by two certified calibration rods of different diameters. Calibration is automatic and can be repeated at any time.
 
The rib measurement system determines the following measurements:
  • Rod cross-section and diameter
  • Rib height at the centre and at the quarter-points
  • Centre distance of the ribs
  • Head width and foot width of the ribs
  • Inclination of the ribs to the rod axis
  • Distance between rows of ribs
  • Specific rib area in several Norms
  • Height and width of longitudinal ribs

Rotation measuring system

The purpose of the device consists in the automated geometric measurement of screws, bolts, pins and similar small objects for quality assurance

The object to be tested is clamped vertically in a quick-action chuck or attached to a magnet in the chuck and, depending on the measuring characteristic, illuminated with high-contrast or transmitted light. The test piece is optically captured by two or three high resolution CMOS black and white cameras and displayed in a window on the computer monitor. So that it is possible to detect larger objects in their entire length, they can be moved in parallel via the linear unit. Using a measuring program that can be largely configured by the user, various parameters such as diameter, thread properties, lengths but also shape and position tolerances, etc. can be measured.

The device is calibrated via a certified calibration standard with different diameter and length intervals. Calibration is automatic and can be repeated at any time.
