Each flanging bore corresponds to a cavity plate in the present invention and punch assemblies, each cavity plate can be along its corresponding flanging bores
Axis direction does linear telescopic movement, and upper mold carries type face, and the retainer that upper mold is cavity plate, all cavity plates are nested in
In mould, and it can move along a straight line along pilot hole.
Present invention also offers the application method of above-mentioned aero-engine annular flame tube array inclined hole flanging die, such as schemes
Shown in 5, including upper mold 22 is raised above along pilot hole, then clamps workpiece 56, and workpiece 56 passes through the type face of lower die 25 and multiple
Positioning pin 23 on uniformly distributed punch-pin 24 positions；Then upper mold 22 declines, and the bearing 5 of 13 tail end of inclined wedge is along inclined wedge jacking block 4
First diving plane of end face, at this time cavity plate 21 be in bearing 5 movement initial position；Upper mold 22 continues to decline, bearing 5
Moved along the inclined-plane linkage section of the vertical plane of inclined wedge jacking block 4 so that 13 outward radial of inclined wedge radiation movement, inclined wedge 13 it is oblique
Face jacks up cavity plate 21, and cavity plate 21 is moved along the bullport of upper mold 22, when bearing 5 move to second of inclined wedge jacking block 4 it is vertical
During face, cavity plate 21 moves to operating position；Upper mold 22 continues to decline, and upper mold 22 and the upper surface of workpiece 56, at this time
Cavity plate 21 keeps operating position constant；Upper mold 22 continues to decline, and drives lower die 25 to decline, and the punch-pin 24 in lower die 25 is convex
Bullport under the pushing tow of the second wear strip 26 on mould backing-out punch 27 along lower die 25 stretches out, and realizes the flange to workpiece 56,
When lower die 25 moves to bottom, flange is completed.
After completing flange, upper mold 22 is raised above, punch-pin 24, cavity plate 21, the phase of 22 lower die 25 of upper mold and workpiece 56
It is to position relationship：Punch-pin 24 exits the flange of workpiece 56 first, and then upper mold 22 is separated with lower die 25, and cavity plate 21 returns to initially
Position, when cavity plate 21 returns to initial position, 56 automatic demoulding of workpiece.
15 component of the second double threaded screw 16 and its second spring is used in the present invention, by spring assist, makes each cavity plate
Initial position can be return back to after flange, so as to fulfill the disengagement function of parts flanged-edge and cavity plate, and spring structure is to oblique
Wedge centripetal thrust force, improves the corresponding speed of the rollback of inclined wedge 13.Using inclined-plane ejecting mechanism, i.e. punch-pin backing-out punch 27 is by lower die
Oblique movement of the punch-pin 24 along flange axially bored line defence line is changed into vertical movement, and the process of the decline of lower die 25 is driven in upper mold 22
In, lower die 25 drives punch-pin 24 to do relative motion, and punch-pin is stretched out along the pilot hole of lower die, is completed to hole flanging；Using inclined wedge
Jacking block 4 realizes the timesharing campaign of cavity plate 21 and punch-pin 24, solves the problems, such as that cavity plate cannot be in time and take off in turn-up process
The locked problem of cavity plate and punch-pin during mould, the order of its timesharing campaign are：During the decline of upper mold 22, cavity plate 21 first stretches out guarantor
Hold in operating position, then upper mold 22 is contacted with lower die 25, and then upper mold 22 drives lower die 25 to decline, in the process punch-pin 24
It is opposite to move and stretch out with lower die 25, complete the flange of device to hole；During upper mold 22 completes flange rise, lower die 25 follows
Upper mold 22 rises, then the process convex mould 24 is moved relative to lower die 25, and is disengaged with the flanging bore of workpiece 56, then upper mold
22 leave lower die 25, and last cavity plate 24 is retracted, and workpiece 56 is completely and mould；Inclined wedge 13 and inclined wedge are reduced using bearing 5
Frictional force and resulting additional example sentence between jacking block 4, make inclined wedge movement more steady.
