Incremental Forming Process For The Accomplishment of Automotive Details

摘要

In the last decades the scenario of the industrial production is remarkably changed, since new market requirements have to be faced by the industries. The market, actually, more and more, asks for vary models and niches product. The necessity to intercept dynamically and to satisfy the demands for the market, driver of the innovation process, involves the necessity to reduce the Time-to-market introducing to new methodologies of engineering, like the 3D-prototyping, for the qualitative and structural analysis of the final component. For these reasons, at the beginning of the nineties, a new philosophy of sheet metal forming process begins to assert on the industrial scene, whose basic logic is to obtain the shape wished through the progressive action of a tool of simple shape. In this job the application of the simplest process of incremental process on an industrial detail -famous in international field like SPIF (Single Point Incremental Forming) - will be described. The process is intrinsically flexible, and therefore is adapted to the rapid prototyping. The cases are still least, notice in the scientific literature, in which the details of industrial interest have been developed by Incremental Forming process; for this reason, the subject of this job is focused on the evaluation of the possibility to obtain real components of the automotive industry through the SPIF process. The job has been carried out in the R.&D laboratory of "Fontana Pietro S.p.A.", leader in the field of die manufacturing and stamping of component of the automotive industry. In particular, two parts of automotive auto body of aluminium sheets have been considered. It has been lead an analysis of technological and process feasibility, optimizing tool path considering experiences to obtain a product/process for the production of auto body prototypes.
