Description
Technical field
The present invention relates to forging special-shape ring manufacturing technology field, specifically a kind of flanged bowl-type ring of GH3536 alloys
The manufacture method of forging.
Background technology
GH3536 alloys are that iron-holder is higher and with chromium and the nickel base superalloy of molybdenum solution strengthening, anti-oxidant, anticorrosive
Property is strong, and hot and cold to shape preferable with welding performance, Long-term service temperature is below 900 DEG C, and short-term operation temperature is up to 1080
℃。
The flanged bowl-type ring forging of GH3536 alloys is a kind of conventional part of aviation field, and it is shaped as flanged (FLGD) bowl
Shape, internal-and external diameter is smaller, and shaping difficulty is big.The existing manufacture method of the flanged bowl-type ring forging of GH3536 alloys has two kinds：
1) setting down, then each several part is welded to obtain bowl-type ring forging entirety；
2) big wall thickness rectangle ring is machined out, bowl-type ring forging is obtained after removing excess stock.
Using first method, material structure, each forging material structure of segmentation manufacture of forging and commissure are all present
Difference, so as to have impact on the overall performance of forging；The release of welding stress can produce forging during following process and use
Raw moderate finite deformation.
The streamline integrality of forging can be destroyed using second method, reduces forging overall performance；Remove a large amount of materials simultaneously
Material not only causes the wasting of resources, and adds process time and cost, manufacturing cycle length, less economical.
The content of the invention
In view of the shortcomings of the prior art, the present invention proposes a kind of manufacturer of the flanged bowl-type ring forging of GH3536 alloys
Method, using special loose tool monolithic molding, the uniform streamline of forging tissue odds is imperfect caused by solving classical production process, keeps away
Welding stress release and waste of material are exempted from, have reduced production cost, shorten the process-cycle, ensure that forging quality.
The technical solution adopted by the present invention is as follows：
A kind of manufacture method of the flanged bowl-type ring forging of GH3536 alloys, is comprised the steps of：
1) rectangle ring billet processed
By the sawing on request of GH3536 alloy bar materials, the good bar of sawing is heated to 1140 DEG C~1160 DEG C and is incubated,
Soaking time is：Effective thickness × 5min/10mm of bar, jumping-up, punching, reaming then are carried out to bar, obtain straight-flanked ring
Base；
2) stairstepping ring billet processed
Pulling plug is inserted into rectangle ring billet endoporus, and segment rectangle ring billet is lain on lower anvil, press drives upper anvil
Apply 1000T~3000T pressure to the segment rectangle ring billet being placed on lower anvil, while manipulator rotates rectangle ring billet, obtains
It is constant to obtain internal diameter, wall thickness reduction, the special-shaped ring billet that outer wall is stepped.
Stairstepping ring billet is enclosed on saddle, saddle is lain on saddle support, and press drives shape face to be matched with stairstepping ring billet
Abnormity on anvil to stairstepping ring billet apply 1000T~2500T pressure, obtain internal diameter expand, the stairstepping ring of wall thickness reduction
Base.
3) bowl-type ring billet processed
Stairstepping ring billet is upside down on lower anvil, heavy caliber end upward, small-caliber end down, by wedge-shaped drift from heavy caliber
End is put into stairstepping ring billet endoporus, and press drives upper anvil to apply 2000T~4000T pressure to wedge-shaped drift, makes wedge-shaped drift
Stairstepping ring billet bulging is pressed into, obtains the bowl-type ring billet that heavy caliber end is swollen.
4) flanged bowl-type ring forging is made
Bowl-type ring billet is put into shaping loose tool, shapes the shape and size in loose tool and flanged bowl-type ring forging profile
Matching, punching pin is put into from the heavy caliber end of bowl-type ring billet, and press drives pressure of the upper anvil to punching pin application 3000T~4500T,
Punching pin is set to be pressed into bowl-type ring billet bulging, bowl-type ring billet swells and fills shaping loose tool inner chamber, finally obtains flanged bowl-type ring forging
Part.
The beneficial effects of the present invention are：1) loose tool monolithic molding is used, the streamline integrality of forging, profile can be kept
Closer to finished product, the surplus that follow-up machining removes greatly reduces, improves stock utilization, shorten the process-cycle size；
2) without welding, ensure that the uniformity of ring forging internal material tissue, avoid caused by welding material structure difference and
Deformation caused by stress release.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
A kind of manufacture method of the flanged bowl-type ring forging of GH3536 alloys, is comprised the steps of：
1) rectangle ring billet processed
By the sawing on request of GH3536 alloy bar materials, the good bar of sawing is heated to 1140 DEG C~1160 DEG C and is incubated,
Soaking time is：Effective thickness × 5min/10mm of bar, jumping-up, punching, reaming then are carried out to bar, obtain straight-flanked ring
Base；
2) stairstepping ring billet processed
Pulling plug 4 is inserted into rectangle ring billet endoporus, and segment rectangle ring billet is lain on lower anvil 3, in press drive
Anvil 2 applies 1000T~3000T pressure to the segment rectangle ring billet being placed on lower anvil 3, while manipulator rotates straight-flanked ring
Base, under the squeezing action of pulling plug 4 and upper anvil 2, the internal diameter of ring billet is constant, and wall thickness reduction, outer wall is stepped.
Stairstepping ring billet 1 is enclosed on saddle 6, saddle 6 is lain on saddle support 7, and press drives shape face and stairstepping ring billet 1
For anvil 5 to the reaming of stairstepping ring billet 1, pressure limit is 1000T~2500T on the abnormity of matching, and anvil 5 squeezes on saddle 6 and abnormity
Under pressure effect, the wall thickness of stairstepping ring billet 1 is further thinned, and internal diameter further expands.
3) bowl-type ring billet processed
Stairstepping ring billet 1 is upside down on lower anvil 3, heavy caliber end upward, small-caliber end down, by wedge-shaped drift 9 from big
Bore end is put into the endoporus of stairstepping ring billet 1, and press drives upper anvil 2 to apply 2000T~4000T pressure to wedge-shaped drift 9, makes wedge
Shape drift 9 is pressed into the bulging of stairstepping ring billet 1, obtains the bowl-type ring billet 8 that heavy caliber end is swollen.
4) flanged bowl-type ring forging is made
Bowl-type ring billet 8 is put into shaping loose tool 10, the shape and size shaped in loose tool 10 are forged with flanged bowl-type ring
The form fit of part 12, punching pin 11 is put into from the heavy caliber end of bowl-type ring billet 8, press drives upper anvil 2 to apply 3000T to punching pin 11
~4500T pressure, punching pin 11 is set to be pressed into the bulging of bowl-type ring billet 8, bowl-type ring billet 8 swells and fills shaping loose tool 10 inner chamber, most
Flanged bowl-type ring forging 12 is obtained eventually.
Especially, in bowl-type ring billet step processed, the different wedge-shaped drift of size can be used at twice or repeatedly to ladder
The bulging of shape ring billet 1, the heavy caliber end of bowl-type ring billet 8 is progressively swollen, avoid time processing from causing ring billet to damage.
Similarly, in flanged bowl-type ring forging step is made, the different punching pin of size can be used at twice or repeatedly to bowl
The bulging of shape ring billet 8, bowl-type ring billet 8 is progressively filled shaping loose tool 10 inner chamber, avoid time processing from causing ring billet to damage.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention is described in detail, it will be understood by those within the art that：It still can be to previous embodiment
Described technical scheme is modified, and either carries out equivalent substitution to which part or all technical characteristic；And these are repaiied
Change or replace, the essence of appropriate technical solution is departed from the scope of technical scheme of the embodiment of the present invention.
