New generation of effective hot forging equipment

The aim of the project is to develop effective methods
to improve forging tool life and regenerate such tools.
to achieve this, laser treatment and surfacing methods are
proposed.

The short service life of forging tools is a significant economic problem of forging production both in POLAND and in those countries with a high level of industrial development. The contribution of tool costs to the total production cost in Polish forges is 10-15%. Forgery tools work in very hard conditions due to high mechanical loads, abrasive wear and the high temperature tempering action. The operating characteristics of such tools depend mainly on the properties of their surface layers. Among modern methods of improving tool service life by forming wear-resistant surface layers are, among others, the technologies of laser surface treatment (LST) and surfacing. Many of those techniques offer the possibility of improving local properties e.g. of impression edges, which is very important in forging tools. The present project proposes the investigation and subsequent application of: * laser surface treatment of severely worn impression layers. The advantage of this method is quick local heating and cooling, which results in a layer of unique properties, that cannot be obtained by other methods (e.g. high hardness and wear-resistance with minimum product deformation). The essential feature of LST technology is computer controllability of the processes and the utilisation of on-line remote diagnostics. All LST processes are environmentally-friendly. * surfacing, which can be applied for life improving and regeneration of dies including those of large overall dimensions. In this way, severely worn tool fragments, particularly edges and corners, can be improved or regenerated. The project development includes: 1. Determination of the working conditions of forging tools for hot work depending on, the forging size and shape, material grade, technical conditions of forging based on laboratory investigation and numerical simulation. 2. Determination of properties of tool surface layers as far as the aspect of their chemical composition, layer applying technologies and treatment are concerned. 3. Organization of investigation stands. 4. Industrial tests. 5. Technical and economical analysis of various tool surface hardening techniques. 6. Drawing up of guidelines for industrial practice. 7. Implementation of the investigation results in domestic forges. The ultimate purpose of the project is, therefore, the drawing up of effective methods of improving the service life and regeneration of forging tools.
