2), the braking cone blank utilizes mechanical clamp to be turned to 2 mould die orifices behind 1 mold forming, the tool that dashes of 2 moulds heads into the braking cone blank in the die, first locating hole of braking cone blank front end face cooperates with the raised step of push rod, towards the tool front end raised step is arranged, after tool is exerted pressure extruding, braking cone blank rear end face is had second locating hole;
3), the braking cone blank utilizes mechanical clamp traversing to 3 mould die orifices behind 2 mold formings, towards tool the braking cone blank is headed in the die, first locating hole on the braking cone blank cooperates with the raised step of push rod, towards the tool front end projection cone is arranged, after tool is exerted pressure extruding, braking cone blank rear end face is gone out first counterbore;
4), utilize mechanical clamp traversing to 4 mould die orifices automatically, towards tool the braking cone blank is headed in the die, first locating hole on the braking cone blank cooperates with the raised step of push rod, the internal orifice dimension of die is greater than the braking cone blank, elongation end towards the tool front end passes described first counterbore and goes out second counterbore, towards tool exert pressure that extruding back braking cone blank is subjected to towards tool pressure and to around diffusion, the braking cone blank back external diameter that is squeezed becomes big;
5), utilize mechanical clamp that 4 mold forming braking cone blanks are turned to 5 mould die orifices, towards tool blank is headed in the mould, step is arranged and with described first counterbore, second counterbore cooperate respectively towards the mother of tool towards front end, the son of mould is punched in the first locating hole place and ejects endoporus, and the braking cone blank tripe portion after the extruding is full after upsetting;
6), with mechanical clamp 5 mold forming braking cone blanks are turned to 6 mould die orifices, the endoporus that directly passes the braking cone blank towards tool is made the braking cone blank of through hole with residual iron filings pass-out.
The present invention mainly utilizes the cold-stamped method, and cold extrusion is a principle of utilizing metal plastic deformation, at normal temperatures the metal in the extrusion die chamber is applied powerful pressure, makes it to extrude from the gap of nib or concavo-convex mould.It makes metal volume do plastic deformation under the prerequisite of not destroying metalline, thereby obtains a kind of processing mode that cuts less or do not have cutting of required part, and realizes mechanization and automated production easily.The surface of braking cone blank is through handling and lubricating, and the control in forming process process program and the mould design, six moulds six that utilize multi-functional position moulding cold extrusion die are towards sharing resistance of deformation and the mould bearing capacity that produces in the product deformation process, and utilize mechanical clamp to make the blank can continuously shaped number uninterrupted characteristics, directly dash and mold the braking cone blank, make its speed of production only can reach per minute 80-90 by six moulds six.Owing to adopted such scheme, the invention enables the blank of braking cone can adopt the manufacturing of cold-stamped method, the consumable quantity of blank is declined to a great extent, can save material and reach 45%, and it is tightr through the cold extrusion materials microstructure, tension, surrender, elongation, the every mechanical performance of impact all are better than machined, have guaranteed product quality.
