Summary of the invention
The technical problem that the present invention will solve is: the hot extrusion forging equipment of the ring flange central siphon of whole forging process that a kind of single device can accomplish the ring flange central siphon is provided, and the hot extrusion forging method that the high ring flange central siphon of a kind of working (machining) efficiency is provided.
In order to solve the problems of the technologies described above, the present invention includes punch and die, also comprise jumping-up movable mold and geocoded activity mould; The die cavity of die is the second order stepped hole, and the macropore of the die cavity of die is descending at last, aperture, and the jumping-up movable mold is provided with the blind hole that is used to insert punch; The geocoded activity mould is provided with and is used for the through hole that punch passes; The lower end of the lower end of jumping-up movable mold and geocoded activity mould all can get into respectively in the macropore of die cavity of die, when the die cavity of die is inserted in the lower end of jumping-up movable mold, the blind hole of jumping-up movable mold and punch over against; When the die cavity of die is inserted in the lower end of geocoded activity mould, the through hole of geocoded activity mould and punch over against.
For the ring flange end face of the workpiece that processes is the plane, jumping-up movable mold lower surface is the plane perpendicular to axis, and the lower surface of geocoded activity mould is the plane perpendicular to axis.
The hot extrusion forging method of ring flange central siphon of the present invention comprises a, blanking; B, jumping-up; C, location; D, moulding; It is characterized in that: described jumping-up, location and three operations of moulding adopt the hot extrusion forging equipment of same aforesaid ring flange central siphon;
B, jumping-up: workpiece after the blanking is heated to the die of putting into forging equipment after the uniform temperature, the jumping-up movable mold is inserted the die cavity of die and is pressed on the workpiece, the blind hole extruding workpiece that is advanced into the jumping-up movable mold under the punch suppresses ring flange to the workpiece jumping-up;
C, location: punch is up, takes out the jumping-up movable mold, and the geocoded activity mould is inserted die and is pressed on the workpiece, and punch is descending to be passed the geocoded activity mould and be pressed into workpiece, on workpiece, forms locating hole;
D, moulding: punch is up, takes out the geocoded activity mould, and the locating hole of the descending insertion workpiece of punch and further extruding hole on workpiece reach projected depth.
Beneficial effect of the present invention: the present invention adopts the auxiliary jumping-up of jumping-up movable mold through two auxiliary movable mold of design when jumping-up, adopt geocoded activity mould assist location during the location; The geocoded activity mould can be prevented occuring bending and deformation when punch contacts with hot workpiece, protects to let the positional precision in the hole on the workpiece, does not need the special operations mould during moulding; Realize that three forging process accomplish in same equipment; Make workpiece in the forging molding process, not need turnover, reduce thermal losses, working (machining) efficiency is high.
