Sangiacomo Mechanical Press Arrives in Sheffield
The FEMM Hub recently purchased a Sangiacomo mechanical press which will be located in the Lea Laboratory in the Department of Mechanical Engineering, University of Sheffield. Sangiacomo is a leading company in the manufacturing of eccentric mechanical presses which are produced in the premises located in Vittorio Veneto, Italy.
The mechanical press has a capacity of 50 tons to study the cut-edge defects due to the stamping process. The electrical laminations are conventionally produced by the stamping process and the process parameters including die/punch clearance, stamping rate, tooling material as well as the laminations materials and their coating affect the quality and functional performance of the electric machines. The press has a motorised ram adjustment with a variation stroke of 12mm-110mm as well as a variable speed of 72-180 spm. This enables it to produce parts with industrially relevant parameters and provide rich data sets for validation of predictive models.
Laminations are made mostly by blanking and piercing processes, the quality of the final product directly affects the performance of the electrical machines. The blanking process results in local plastic deformation and texture modification in the materials which will impact the magnetic and mechanical performance of the electric motors and transformers. Therefore, the new equipment facilitates a better understanding of the global and local magneto-mechanical properties of the sheet material at the cut edge and vicinity area to optimise design parameters used for the final products.
If you would like more information on the blanking and stamping, please contact Mr Luke Jones or Dr Hassan Ghadbeigi.
