Description
Technical field
The present invention relates to the stamp forming technology of Aircraft Sheet Metal Parts, a kind of anti-fold bending semicanal finishing die
Tool and manufacturing process.
Background technology
Stamping as the big branch of sheet forming one, plays pivotal role to commercial production.Shape at conventional ones
In, generally use flange fixing installation to carry out assist formation, but flange fixing installation limits plate flowing based on passive mostly.Shaping shape
During the workpiece that shape is complicated, deflection is bigger, the amount of flow produced due to plate each several part is different, easily produces wrinkle wrinkling, dead, wall
The defects such as thick excessive thinning even drawing crack, the serious range of application restricting process for stamping and forming.
Airplane parts has a large amount of half pipe part in manufacturing at present, uses conventional process flow: bent pressing mold strikes out
After shape, workman is according to supporting after supporting tire hand finish cutting surplus.Owing to the stamping rear fold of bending die is many, sometimes occur
Dead wrinkle causes part rejection, and workman's craft equating fold workload is big, and semicanal surface quality of workpieces is poor.
Summary of the invention
In order to solve the fold produced in punching course, dead wrinkle, resilience problem, the invention provides a kind of anti-fold
Bending semicanal shaping dies and manufacturing process, the cushioning effect Dominant Facies of traditional stamping technology with elastic fluid is combined with
Solve the problems referred to above to effect.
A kind of anti-fold bending semicanal shaping dies, containing upper die and lower die and the multiple anti-pleat that is placed between upper and lower mould
Wrinkle cushion pad, lower mold is the blocks that upper and lower surface is parallel, and lower mold upper surface is provided with the matrix face consistent with External Shape profile；
Upper mold is provided with the convex face matched with lower mold matrix face, and convex face can embed in the matrix face of lower mold, and the two spacing is institute
The material thickness of part to be shaped.Anti-fold cushion pad is made up of soft material, and for flat shape, contours profiles is slightly less than
Lower mold matrix facial contour profile.Use this anti-fold bending semicanal shaping dies to carry out part forming, be on according to being placed in
Anti-fold cushion pad number between lower mold and formation of parts successively, comprise the steps of
1, placing all anti-fold bufferings to be padded on lower mold matrix face, part raw material to be formed is placed on cushion pad,
Then the convex face of upper mold with the involutory compression of lower mold, i.e. upper mold is embedded in the matrix face of lower mold, complete the one-off drawing of part；
2, remove anti-fold cushion pad the most successively, often remove an anti-fold cushion pad and repeat step 1, until not placing anti-
Fold cushion pad, upper die and lower die and raw material reach blind-mate, complete the final shaping of part.
The present invention has following features: 1, this mould structure is simple, easy to operate, and practicality is high.2, this mould need not pin
Nail location, service life is long.3, this mould is through multi-drawing, substantially increases part with mould laminating degree, decreases
Resilience, reduces the patch work amount of workman.4, this mould is through multi-drawing, reduces what material produced because force is excessive
Phenomenon of rupture, reduces the mechanical property requirements to material.5, this mould uses rubber blanket to buffer part forming process,
Avoid part fold, the generation of dead wrinkle.6, motility of the present invention is strong, can be by changing concave, convex profile and anti-fold cushion pad
Shape, half pipe part realizing complicated surface dead wrinkle anti-fold, anti-, anti-fracture stamping.

Detailed description of the invention
As it is shown in figure 1, a kind of anti-fold bending semicanal shaping dies, containing upper mold 1, lower mold 8, it is placed between upper and lower mould
Multiple anti-fold cushion pad, lower mold 8 is the blocks that upper and lower surface is parallel, and lower mold 8 upper surface is provided with and External Shape profile
Consistent matrix face 7；Upper mold 1 is provided with the convex face 2 matched with lower mold matrix face 7, and convex face 2 can embed the recessed of lower mold 8
In profile 7, the two spacing is part raw material 3 thickness to be formed.Anti-fold cushion pad can be made up of soft material, for
Flat shape, contours profiles is slightly less than lower mold 8 matrix face 7 contours profiles.
When carrying out part forming, the formation of parts successively according to the anti-fold cushion pad number being placed between upper and lower mould,
First, placing all anti-fold bufferings and be padded on lower mold 8 matrix face 7, part raw material 3 to be formed is placed in all cushion pads
On, then the convex face 2 of upper mold 1 with the involutory compression of lower mold 8, i.e. upper mold 1 is embedded in the matrix face 7 of lower mold 8, complete part
One-off drawing；Then, then remove anti-fold cushion pad successively, often remove an anti-fold cushion pad and repeat previous step, until not
Placing anti-fold cushion pad, upper mold 1, lower mold 8 and part raw material 3 reach blind-mate, complete the final shaping of part.
As it is shown on figure 3, upper mold 1 and the lower mold 8 of mould are fixed on common punch press, by convex face 2 and matrix face 7
Cooperate to location.By anti-fold for upper strata cushion pad 4, the anti-fold cushion pad in middle level 5, the anti-fold cushion pad of lower floor 6 by from upper
Order under to stacks to matrix face 7, by part raw material 3 as in plane in lower mold 8.Start punch press, upper mold 1 is pressed into
In lower mold 8, it is achieved stretching for the first time, such as Fig. 4.By punch press reduce, the anti-fold cushion pad in upper strata 4, the anti-fold cushion pad in middle level 5,
The anti-fold cushion pad of lower floor 6 is restored to initial configuration.Take out the anti-fold cushion pad in upper strata 4, by the part after stretching for the first time
As on the anti-fold cushion pad in middle level 5, such as Fig. 5.Start punch press, carry out second time and stretch.Reduction punch press, takes out middle level anti-fold
Cushion pad 5, by the part after second time stretching as on the anti-fold cushion pad of lower floor 6, such as Fig. 6.Start punch press, carry out third time
Stretching.Reduction punch press, takes out the anti-fold cushion pad of lower floor 6, by the part after third time stretching as in lower mold 8, such as Fig. 7.Open
Dynamic punch press, carries out the 4th stretching.Reduction punch press, part forming is complete.
