Deflection is distributed, and primary heating completes press-bending and blocking process；
3) finish-forging.
Step 2) includes:
201) it installs a mold on forging equipment, mold is preheating between 180 DEG C~300 DEG C；
202) bar is heated to 450 DEG C；
203) die cavity is lubricated using industrial lard lubricant, bar is placed in the die cavity of mold, is forged.
In step 2), after blank is bent, both ends are upwarped, so as to form both ends of the blade tenon.
The mold that the manufacturing process of bias adjustable vane of the invention uses, using bending blocking Integral mold, including upper mold and
Lower die, wherein lower die has bottom base, and bottom base is equipped with first to lower recess with the curved outer shape cooperation of blade
Groove, while it being equipped with pre- forge chamber in the first groove side, first groove one end is equipped with horizontal bench；Upper mold has upper base
Seat, top base are equipped with convex portion, and the convex portion and the curved inboard shape of blade are coincide.
The pre- forge chamber is to coincide with the blade side-glance shape after press-bending second recessed on the bottom base of lower mold
Slot.
Second groove both ends are equipped with the pit for being deeper than the second groove；Convex portion both ends have the block of fixed blank.
Blocking shapes integration mold material selection 5CrNiMo.
The invention has the following beneficial effects and advantage:
1. the present invention changes original forming mode, is bent by design and blocking shapes integration mold reasonable distribution and becomes
Shape amount, and primary heating completes press-bending and blocking process；The more former forming of forging produced using the forming mode of two forging of a fire
Mode improves stock utilization, and can avoid the coarse-grain problem generated because finish-forging deflection is insufficient, improves product quality.
2. solving the coarse-grain quality problems of aluminum alloy materials blade using after the method for the present invention, while improving material benefit
With rate about 30.2%, production cost is reduced.

Specific embodiment
The present invention is further elaborated with reference to the accompanying drawings of the specification.
A kind of manufacturing process of eccentric adjustable vane of the present invention, including following process:
1) upset is assembled:
2) fire carries out press-bending and blocking: being bent by design and blocking forming integration mold is reasonable
Deflection is distributed, and primary heating completes press-bending and blocking process；
3) finish-forging.
Step 2) includes:
201) it installs a mold on forging equipment, mold is preheating between 180 DEG C~300 DEG C；
202) bar is heated to 450 DEG C；
203) bar is placed in the die cavity of mold, carries out blocking.Mould is lubricated in blocking process industrial lard lubricant
Chamber is avoided that frictional force is excessive between blank and mold in this way, does not become ideal pre- forging shape, and be avoided that using it
His lubricant blank flows the defect of too fast generation.
The mold that the manufacturing process of bias adjustable vane of the invention uses, using bending blocking Integral mold, including upper mold 1 and
Lower die 2, wherein lower die 2 has a bottom base 201, and bottom base 201 is equipped with blade curved outer shape cooperation to recessed
The first sunken groove 202, while it being equipped with pre- forge chamber in 202 side of the first groove, 202 one end of the first groove is equipped with horizontal bench
205；Upper mold 3 have top base 301, top base 301 be equipped with convex portion 302, the convex portion 302 and blade it is curved in
Side shape is coincide.
Pre- forge chamber is the second identical groove with the blade side-glance shape after press-bending on the bottom base 201 of lower mold 2
203。
Second groove, 203 both ends are equipped with the pit 204 for being deeper than the second groove；302 both ends of convex portion have fixed blank 1
Block 303.This set is conducive to the fixation of blank, and blank 1 is put in correct position when blocking, when finish-forging shapes, leaf
The fillet of piece blade maximum would not generate the defect being not fully filled.
Key technology of the invention is embodied in step 2), bends and the design of blocking integration mold, one fire two of equipment are forged
After the development and utilization of function and blank are bent, both ends are upwarped, so as to form both ends of the blade tenon, without increasing former stick again
Expect diameter, so that raw material be greatly saved, and increases blocking die cavity, reasonably distribute deflection, forging is avoided to generate
Coarse grain defect.
In the present invention, it is a set of that bending process needs to bend blocking Integral mold, bending die material selection 5CrNiMo, such as Fig. 1 institute
Show.
As shown in Figure 2 to 4, the overall process schematic diagram of deformation and blocking forming is placed, bent from bar for blank.First
It installs a mold on forging equipment, mold is preheating between 180 DEG C~300 DEG C；Bar (material 2A70) is heated to 450
DEG C, die cavity is lubricated using industrial lard lubricant when forging.
As shown in Fig. 2, bar is placed in lower die, the step of 4mm is made in lower die one end, positions convenient for bar.Bar
After putting surely, upper mold is moved downward, and bar is bent to Fig. 3.
Press-bending part is inverted to pre- forge chamber with pliers immediately to the right and carries out blocking by workpiece after bending, as shown in Figure 4.
The method of the present invention changes original forming mode, carries out press-bending and blocking, end using upset aggregation, a fire
The forming mode for forging three processes, is bent by design and blocking shapes integration mold reasonable distribution deflection, and a fire heating
Press-bending and blocking process.The more former forming mode of forging that the forming mode of one fire, two forging is produced improves stock utilization,
And can avoid the coarse-grain problem generated because finish-forging deflection is insufficient, improve product quality.
