Avoiding expensive tool damage and its consequential costs in stamping and forming technology with the help of reliable uEye CP industrial cameras.

Evolution in the press shop

Intelligent, camera-based tool protection in stamping and forming technology

Boosting efficiency through digitalisation - almost no branch of industry can evade it. Also operators of press shops are increasingly networking their production. But - regardless of whether it's a single press or press lines - it's not always necessary to replace the entire plant in order to stay up to date. Retrofitting existing lines, true to the principle of "sensible evolution instead of cost-intensive revolution", is often the order of the day. With Visual Die Protection, Schuler Pressen GmbH from Göppingen offers a solution for avoiding expensive die damage and its consequential costs in stamping and forming technology - retrofittable for existing lines. Equipped with industrial cameras from IDS Imaging Development Systems GmbH and intelligent software, the production process can be monitored as required.

Application

The principle of the system is simple:  Visual Die Protection (VDP) detects possible causes of die damage in the press shop at an early stage and stops the line in fractions of a second before damage and downtime occur. Different monitoring functions can be set up for the various areas in the press installation space. This way, a wide range of error sources can be covered to prevent unforeseen incidents. The probability of failure is reduced and the safe operation of the systems is ensured.

The control functions range from checking the component position to foreign object detection and in-process inspections to the targeted monitoring of individual tool functions. For example, if a foreign object, such as a scrap of sheet metal from the previous press pass, is detected in the die, the press stops automatically so that the foreign object cannot push into the die surfaces or cause damage.

In addition, all image and analysis data are available to the customer for complete traceability. For continuous improvement processes, the system simultaneously links image and process data and optimises its settings with the help of intelligent data analyses. It only intervenes in the production process when there is a critical deviation. Visual Die Protection thus ensures greater process reliability of production plants, prevents tool damage, increases plant availability and secures the user's ability to deliver. Especially in just-in-time supply chains, this is a decisive competitive advantage.

Camera

The image data on which the Schuler system is based is supplied by uEye CP industrial cameras from IDS. CP stands for "Compact Power" and symbolises compact, visual power packs for industrial applications of all kinds. They offer maximum functionality with extensive pixel pre-processing and are perfect for multi-camera systems thanks to the internal 120 MB image memory for buffering image sequences. The GigE cameras with a size of only 29 x 29 x 29 millimetres score particularly well in terms of light sensitivity, dynamic range and colour reproduction. This makes them predestined for applications that need to deliver a perfect result even in low light conditions, such as in quality assurance or automation. "The quality of the image data convinced us. Even under rather unfavourable lighting conditions in press shops, the camera provides perfect source material for our inspection systems," explains Christoph Pölzl - Project Manager in the Digital Solutions division at Schuler Pressen GmbH. For integration, the company used the IDS Camera Manager, a central and convenient tool for managing all uEye industrial cameras.
