Specific implementation mode
Air outlet end cone hole-flanging device of the present invention is further described by Fig. 1 to Fig. 3.
A kind of numbers of hot-side engine air outlet end cone integrated production method, includes the following steps：
1) use 200T CUTTING automatic blankings lines that the disk of shape Φ 185mm-225mm is carried out feeding, this product
The size used is Φ 205mm, and feeding per minute 40 and state are double feeding；
2) coat drawing oil on disk, upper surface drawing oil in 0.5mm or so, it is right after 250T punching machines receive disk
Disk punching stretch, makes disc be recessed, and is similar to hemisphere face, and form big mouth in wafer surface；
3) squeezing shaping is carried out to it using 250T punching machines, the disk after punching stretch, which is shaped to required profile, to be gone out
The appearance profile of gas end cone 6, and closed osculum profile is formed, the angle of the osculum and big mouth is 100 °；
4) 160T punching machines is utilized to cut off the extra material of big mouth outer edge；
5) 160T punching machines are utilized to handle the outer edge flange of big mouth；
6) it utilizes 160T punching machines by closed small wealthy perforation, forms perforative osculum；
7) to the processing of the inward flange hole flanging of osculum；
8) big mouth outer edge is repaiied using 160T punching machines, controls big mouth flatness.
In the technical program, step 7) is practical difficulties, need to be realized by following device.
A kind of air outlet end cone hole-flanging device, including upper die and lower die 7, upper die and lower die 7 can relatively move, and further include support
Backing plate 1, punch-pin cushion block 2, dual-gripper locating piece 3 and Burring Punch 4；The support backing plate 1 is installed on lower die 7, and can be relative to
Lower die 7 moves up and down；There is the punch-pin cushion block 2 convex block 22 and fixed block 21, the lower end of the fixed block 21 to pass through supporting pad
Plate 1 welds or is spirally connected lower die 7, and part is located at the top of support backing plate 1 thereon, and the convex block 22 is shaped in fixed block 21
Side wall；The dual-gripper locating piece 3 includes pedestal 31 and positioning mould 32, and the pedestal 31 is installed on support backing plate by screw
On 1, the positioning mould 32 is shaped in the upside of positioning seat and offers through-hole 322, and positioned at the top of convex block 22, confesses
Gas end cone 6 positions；The Burring Punch 4 is screwed in the upper surface of convex block 22, and corresponding with about 322 through-hole, when
When upper die and lower die 7 relatively move, the upper end of Burring Punch 4 may pass through through-hole 322.
Further, it grafting or is spirally connected there are four guide post 8 in the lower die 7, supports and open up that there are four lead on backing plate 1
To hole 5, guide post 8 is arranged in the one-to-one correspondence of pilot hole 5 in pilot hole 5, is equipped between the support backing plate 1 and 7 plate of lower die
Resetting spring, the i.e. upper end of resetting spring are resisted against the lower surface of support backing plate 1, and lower end is resisted against the upper surface of lower die 7, to
Realize installation and relative movement of the support backing plate 1 in lower die 7, herein it should be noted that, movement of the upper padding plate relative to lower die 7
Stroke is 15mm.
Further, there is the positioning mould 32 positioning surface 323 and locating slot 321, air outlet end cone 6 to be assemblied in positioning surface
On 323, and engage with locating slot 321.
Further, the pedestal 31 takes the shape of the letter U, and the convex block 22 is located in the U-shaped mouth of pedestal 31, to facilitate dual-gripper fixed
Position part 3 moves up and down.
The operation principle of the technical program is：The air outlet end cone 6 of non-hole flanging 61 is positioned to positioning mould 32, positioning surface
323 are bonded with the inner wall of air outlet end cone 6, and the concave surface formed after card slot and shaping fastens, and realizes air outlet end cone 6 and positioning mould 32
Positioning, osculum are corresponding with through-hole 322；Driving upper mold moves down, after upper mold and the contact of air outlet end cone 6, the column in upper mold
It is contacted with support backing plate 1, and pushes support backing plate 1 while moving down, support backing plate 1 drives dual-gripper locating piece 3 and outlet
End cone 6 moves down；Air outlet end cone 6 slowly close to Burring Punch 4 and is in contact with it, when moving down until Burring Punch 4
Upper end pass through osculum, since in design, the diameter of Burring Punch 4 is more than osculum diameter, so the upper end of Burring Punch 4 exists
During lower mouth, the inward flange of osculum can be made to turn down outward, to realize that hole flanging 61 operates.It should be noted that when going out
When gas end cone 6 is located in positioning mould 32, air outlet end cone 6 is heeling condition, and osculum is to be vertically oriented to.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
