Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-4, Fig. 1 is the generalized section of welding neck flange; Fig. 2 is the generalized section of the first mould according to some illustrative embodiment; Fig. 3 is the structural representation of the second mould according to some illustrative embodiment; Fig. 4 is the generalized section of the 3rd mould according to some illustrative embodiment.
The hollow forging mould of some illustrative embodiment, comprising: the first mould 10, and the diameter axially offering columniform first perforate 11, first perforate 11 along it is identical with the diameter of flange part 1; The second mould 20 that top external diameter is identical with the diameter of the first perforate 11, the outside on its top is provided with folding platform 22, the height axially offering columniform second perforate 21, second perforate 21 along it is identical with the length of flange neck 2, and is positioned at the center of the first perforate 11; Columniform 3rd mould 30, its diameter is equal with the internal diameter of flange neck 2.
In order to ensure the precision of mould, preferably, the first perforate 11 is positioned at the center of the first mould 10; Second perforate 21 is positioned at the center of the second mould 20.
Preferably, the 3rd mould 30, the diameter of its one end is equal with the internal diameter of flange neck 2, and the diameter of the other end is less than the internal diameter of flange neck 2.
Preferably, the top edge of the first perforate 11 is fillet.
Preferably, the lower limb of the 3rd mould 30 is fillet.
Preferably, the second perforate 21 is trapezoidal along the section of its central axis direction.
As shown in Figure 5, be the first mould, the second mold use state diagram in above-described embodiment.
During forging, the folding platform 22 of the second mould 20 is stuck in the lower end of the first mould 10, forms the shape of flange blank, raw material hollow pipe is placed in the second perforate 21, is placed in raw material hollow pipe by the 3rd mould 30, and during to prevent from forging and pressing, the internal diameter of hollow pipe diminishes.
As shown in Figure 6, be the generalized section of the 4th mould according to some illustrative embodiment.
The hollow forging mould of some illustrative embodiment, also comprises: the 4th mould 40, and its bottom surface offers circular groove 41, and the diameter of groove 41 is identical with the diameter in flange RF face 3.
Preferably, the centre of groove 41 offers circular hole 42, is placed in raw material hollow pipe by the 3rd mould 30 by circular hole 42.
As shown in Figure 7, be the first mould, the second mould, the 4th mold use state diagram in embodiment.
During forging, the 4th mould 40 is positioned at the top of the first perforate 11.
As shown in Figure 8, be the generalized section of the 5th mould according to some illustrative embodiment.
The hollow forging mould of some illustrative embodiment, also comprises: columniform 5th mould 50, and the diameter of its one end is identical with the internal diameter of flange neck 2, and the diameter of the other end is greater than the internal diameter of flange neck 2.
Preferably, the lower limb of the 5th mould 50 is fillet.
Because the height before the forging and stamping of raw material hollow pipe is higher than mould, therefore first utilize the first mould and the forging and stamping of the second mould, the internal diameter of hollow pipe upper end can reduce, and by the 5th mould 50, the internal diameter of hollow pipe is returned to original size; Again the 4th mould 40 is placed in the top of the first perforate 11, by its circular hole 42, the 3rd mould 30 is placed in raw material hollow pipe, forges into the blank of welding neck flange, obtain finally by simple post processing the flange meeting dimensional requirement.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
