Method of manufacturing a shaped component made of metal having a very high hardness, especially steel, and component obtained

摘要

A metal sheet (2) is raised to a temperature above the minimum quenching temperature and below the usual temperatures for the hot forming of the metal of the sheet; this sheet (2) is inserted between two dies (3, 4) which are then clamped and cooled so as to combine shaping with quenching. In this way, components are obtained, especially steel components, the Brinell hardness of which may exceed 600 kg/mm<2> and which include at least one dihedron whose internal radius of curvature may be less than or equal to twice the thickness; this thickness may reach 60 mm. <IMAGE>
