Abstract

An automatic installation for obtaining in large series circular pieces of small thickness, such as notably spring diaphragms, for the automobile industry, in forming, swaging, quenching, tempering and peripheral tempering stations, these various working treatment stations being placed one after the other so that the pieces to be worked be successively transferred from one station to another, characterized in that: it includes a machine allowing realizing automatically and in series a forming operation by hot swaging and quenching of spring diaphragms or circular pieces; each entirely automated working station includes a press provided with individual heating means, said working stations receiving the pieces one by one from said automatic machine, with the assistance of transfer means withdrawing one by one the pieces to be treated from the quenching stations of the automatic machine for transferring them successively thereafter and one by one to each of the working stations; means are provided for blowing into each working station cold air in the central portion of the piece placed on the corresponding press, so as to maintain the temperature of this central portion at a value less than the temperature of the periphery, during the peripheral tempering treatments of the latter; it includes a final cooling station on which the piece incoming from the preceding stations is subjected to a cooling via blown cold air and; means are provided for storing the treated pieces by stacking them so as to ensure thereafter the discharge of the treated pieces conditioned in stacks.
