(1), the dish circle of essence being taken out behind the sizing expects that automatic shearing is cut into single outer tube blank in cold headers;
(2), utilize the mechanical clamp clamping with described outer tube blank, deliver to a mould die orifice of cold extrusion die, the tool that rushes by a mould heads into the outer tube blank in the die, because top, die rear end is blocked up push rod is arranged, the inwall of die bottom has chamfering, rushing under the extruding that tool exerts pressure, the upsetting of outer tube blank is flat, and simultaneously upsetting goes out interior chamfering;
(3), utilize mechanical clamp to be turned to the mould die orifice No. two the outer tube blank behind mold forming, the tool that rushes by No. two moulds heads into the outer tube blank in the die, because top, die rear end is blocked up push rod is arranged, the inwall of die bottom has chamfering, rushing under the extruding that tool exerts pressure, the upsetting of outer tube blank is flat, and simultaneously upsetting goes out interior chamfering;
(4), utilize mechanical clamp traversing to No. three mould die orifices the outer tube blank behind No. two mold formings, by rushing tool the outer tube blank is headed in the die, because there is bundle bar sizing area the die lower end, rushing under the extruding that tool exerts pressure, with outer tube blank lower end Shu Chengxiao external diameter, and go out the first locating hole in the upper end upsetting;
(5), the outer tube blank behind No. three mold formings is utilized mechanical clamp automatic cross to four mould die orifice, by rushing tool the outer tube blank is headed in the die, the first locating hole on the outer tube blank with rush tool front end projection cone and cooperate, rush tool exert pressure the extruding under, outer tube blank front end is gone out the first counterbore;
(6), the outer tube blank behind No. four mold formings is utilized mechanical clamp automatic cross to five mould die orifice, by rushing tool the outer tube blank is headed in the die, the first counterbore on the outer tube blank with rush tool front end projection cone and cooperate, rushing under the extruding that tool exerts pressure, outer tube blank front end face is gone out the second counterbore;
(7), the outer tube blank behind No. five mold formings is utilized mechanical clamp automatic cross to six mould die orifice, by rushing tool the outer tube blank is headed in the die, rushing the tool front end has projection cone to cooperate with the second counterbore, rushing under the extruding that tool exerts pressure, outer tube blank front end face is gone out the 3rd counterbore and the second dark locating hole, make the outer sleeve blanks of final molding.
Beneficial effect of the present invention is as follows:
(1), the present invention mainly utilizes the cold-stamped method, utilize the principle of metal plastic deformation, at normal temperatures the metal in the extrusion die chamber is applied powerful pressure, make it from the gap of nib or concave-convex mold, to extrude, under the prerequisite of not destroying metalline, make metal volume do plastic deformation, thereby obtain a kind of few cutting of required part or without the processing mode of cutting, and realize easily mechanization and automated production;
(2), the surface of outer tube blank is through processing and lubricating, and the control on forming process process program and the Design of Dies, utilize six moulds, six punchings of multi-functional position moulding cold extrusion die to share resistance of deformation and the mould bearing capacity that produces in the deformation of products process, and utilize mechanical clamp to make the blank can continuously shaped continual characteristics, directly be washed into type by six moulds six and go out pneumatic inside and outside tooth joint blank, make its speed of production only can reach per minute 70-80;
(3), the present invention adopts the manufacturing of cold-stamped method, so that the consumable quantity of blank declines to a great extent, stock utilization reaches 95%, and it is tightr to get materials microstructure through cold extrusion, tension, surrender, elongation, the every mechanical performance of impact all are better than machined, have guaranteed product quality.
