Sensor-controlled bevelling system for automated welding seam preparation of flat steel plates. The stable portal construction including application-oriented design of the cutting head supports all types of upper side or bottom side cuts with sensor-controlled online edge tracking.
A laser camera measures the workpiece position and tracks along the upper edge, ensuring the requested land heights with a tolerance of +/- 0.5 mm even compensating heat distortion. The system processes the required bevels, which are defined by simply clicking and inserting the geometry parameters in a CAD drawing of the component, with the specially developed software.
Sensor supported systems can be provided with the igm ibs oxy and plasma cutting machine which are optimized for all mechanical and control requirements for chamfering flat sheet metal. This special characteristic was made possible by the development of a parallelogram-like cutting head, on which the cutting torche, movable in two axes, is mounted. This unit is fitted onto a stable gantry, running on rails, with a cross slide and a vertical slide to take up the parallelogram. The special design of the cutting head allows chamfering of flat sheet metal with any and also alterable chamfer angles on straight or curved cuts.
AUTOMATIC SHEET THICKNESS MEASUREMENT
A highly accurate seam joint preparation while maintaining a specified land height or a specified seam volume requires not only the exact tracking of the cutting torch along the contour but also the exact detection of the sheet thickness. For this purpose, the igm bevelling machine can be equipped with an automatic sheet thickness measurement.
