Tittle:
Intelligent control system tool for sheet drawing
Summary:
Czech university has developed an intelligent control system for sheet drawing, which lowers the deformation limit in the critical areas of stamping and also lowers direct and indirect costs. The offered solution uses numerical simulation in combination with intelligent control system tool for sheet drawing. Scientists are looking for partners interested in further research and development based on a technical cooperation and for companies interested in production under a license agreement.
Description:
The Czech researchers specialized in drawing technologies have developed technology dealing with growing requirements for processing materials with specific properties, such as aluminium, magnesium or titanium based alloys or high - strength steel sheets. There is a growing pressure to utilize such materials due to requirements for reducing of the environmental impact and utilization of advanced technologies.

The proposed solution is based on the creation of control system tool for sheets drawing using numerical simulations and adaptive changes of technological parameters during drawing process. Correction of technological parameters during own production is done on the basis of recorded drawing process quantities and theoretical calculations from the numerical simulation of given process.

In comparison with competitive solution offered on the market, the key innovation is ability to actively change technology parameters during drawing sheets of special metal alloys. Currently available competitive technologies solve such issue by changing system settings in a subsequent reliability tests. Such procedure brings delays and may ends in losses due to manufacturing of non-conforming products.

As a limiting factor of a drawing technology is a maximal possible deformation of formed material at chosen technological conditions. Implementing of new material types with specific utility properties means also development of progressive technological procedures which enable to process these materials.

The result of the long-term development is a system of tool management for mould drawing, which allows processing alloys with specific performance properties while maintaining their rigidity and reduces their weight. Tests have been carried out on a moulding model having irregular shape.

Application potential of proposed solution can be found mainly in the automotive industry and branches processing special metal alloys using drawing technology.

Scientists are looking for partners interested in further research and development based on a technical cooperation and for companies interested in production under a license agreement.
