A system for die monitoring based on the latest camera technology has been developed by Schuler. With the help of these cameras, foreign bodies and other potential hazards can be detected before systems and parts become damaged.
By way of example, a wrench left behind in the die is every press operator’s nightmare. When the machine starts up, damage to both the die and part being formed is inevitable. To address this problem, Schuler has developed ‘Visual Die Protection’, a camera-assisted monitoring system that can eliminate costly die repairs, downtime and even complete production stoppages.
With Visual Die Protection, not only do cameras detect the presence of foreign bodies such as wrenches or punch scraps, the system also checks whether the die is properly connected and verifies that the blanks have been correctly inserted, formed and removed. The system is equally able to recognise both cracks in the part itself and potential damage to the centring and ejector
pins. If any abnormalities are found, the press is stopped to prevent the situation from getting worse.
During operation, the cameras first create reference images of the relevant die before production begins. During this imaging process, operators mark critical areas that require particularly accurate monitoring, such as the centring and ejector pins. While the production process is running, artificial intelligence is used on a separate computer to perform a real-time comparison of current images with the original condition of the die, thus allowing an immediate response if any discrepancies are found.
