Abstract
A method of manufacturing a sheet metal panel, provided with a design of distribution of interior hollow passages defined by parts raised by expansion or expansion of at least one of two sheets integrated in a unitary assembly, method comprising the steps of: arranging a set composed of at least two metal plates placed side by side with metal to metal contact in an interfacial zone or between two faces thereof; hot rolling said composite assembly, at a temperature comprised within the range of 454.4ºC to 515.5ºC until obtaining a thickness reduction of 14% to 75% until integrally uniting said sheets with each other on said contact face with a force of relatively weak unión, and thus form a unified piece; partially annealing said blank at a temperature comprised within the range of 357.2ºC to 371.1ºC for a period of 1 to 3 minutes, to eliminate the effects of forging or working hardening, coming from said hot rolling, expanding by less one of said plates between a pair of matrices subject to each other, of which at least one has a design of distribution of cavities practiced and corresponding to said design of distribution of internal hollow passages, by injection between said sheets of a pressurized fluid, so as to form an expanded panel with interior passages; and re-annealing said panel, this second time at a temperature comprised between 399ºC and 538ºC for a period of 10 to 60 minutes, in order to significantly increase the strength or tenacity of the connection between said sheets in said interfacial zone.
