The manufacturing process of structure element for aircraft construction, including cold hammering differential

摘要

The manufacturing process of structure element for aircraft construction, including cold hammering differential.The present invention relates to a process for the manufacture of a product corroido or an element of the structure multifunctional monolithic aluminum alloy comprising a step of processing the hot, characterized by the fact that, subsequent to processing the hot, buy Ende also at least one processing step by plastic deformation of the cold.In which required at least two zoias this structure element, generalized median different plastic deformation of at least 2%, and preferably, different from at least 3%.The invention allows the manufacture of structure elements especially useful for aircraft construction, presenting properties of employment variables in space and geometrical characteristics identical to those of the elements present.The process according to the invention, is economic and controllable, and can remarkably affect the properties of employment for parts which are not quenched.
