For achieving the above object, a kind of forging equipment for moulding base plate for annealing furnace that the utility model is designed, comprise forging press, on the tup of described forging press, patrix is installed, on the bearing of described forging press, counterdie is installed, on the forging plane of described upper die and lower die, is respectively equipped with the round recessed matching with dome platform on base plate for annealing furnace.By add respectively the round recessed for the dome platform of moulding base plate for annealing furnace on the forging plane of upper die and lower die, like this, can, first with the blank material of casting technique shaping disc structure, then with this equipment, described blank material be forged into the disk blank with dome platform; Finally with machined, described disk blank is molded into finished product; Due in the forging stage; large dendritic crystal in blank material and columnar grain can become the axle recrystallized structures such as crystal grain is thinner, of uniform size through forging; and the pore in blank material, sand holes, loose and segregation etc. also can be through forging compacting and seam; so disk blank has institutional framework and good mechanical property closely; thereby improved the mechanical strength of finished product, extended the service life of finished product.
In such scheme, the structure of described upper die and lower die is identical.Like this, in actual production process, upper die and lower die can exchange, thereby have reduced production cost.
In such scheme, the central axis of the round recessed of described upper die and lower die is located along the same line.
In such scheme, the central axis of the round recessed of described upper die and lower die is all positioned on the central axis of described tup.
The utility model has the advantage of:
1, by add respectively the round recessed for the dome platform of moulding base plate for annealing furnace on the forging plane of upper die and lower die, like this, can, first with the blank material of casting technique shaping disc structure, then with this equipment, described blank material be forged into the disk blank with dome platform; Finally with machined, described disk blank is molded into finished product; Due in the forging stage, large dendritic crystal in blank material and columnar grain can become the axle recrystallized structures such as crystal grain is thinner, of uniform size through forging, and the pore in blank material, sand holes, loose and segregation etc. also can be through forging compacting and seam, so disk blank has institutional framework and good mechanical property closely, thereby improved the mechanical strength of finished product, extended the service life of finished product;
2,, by described upper die and lower die are designed to identical structure, like this, in actual production process, upper die and lower die can exchange, thereby have reduced production cost.
