Description
Technical field
It is specifically a kind of to low-durometer material bending and forming technology this application involves aircraft sheet metal manufacturing field, especially
Bending Mould and the bending and forming guard method for preventing bending trace, are particularly suitable for the nothing containing aluminium coating aluminium alloy sheet part
Trace bending and forming.
Background technology
Aluminium coating is the fine aluminium protective film that plane aluminium alloy plate is used to improve product anti-corrosive properties, due to its intensity and firmly
Degree is far below mold, and sheet metal bending process easily generates damage.Bending trace is material bending process by mold localized high intensity
It squeezes, through-thickness produces relative sliding with lower die after collapsing and form the surface with certain depth, width and seriously damage again
Hinder defect.More visible surface is just formed when bending trace depth is larger and agrees wound, or even the complete breakaway of aluminium coating, alloy-based occurs
Body is directly exposed；Especially aluminium alloy bending part presentation quality, corrosion resistance, service life etc. are produced bigger effect.
Currently known sheet bending mainly takes V-type lower die structure, and Forming Theory is plate die cavity under by V-type
The upward support force in mouth both sides, while upper mold is pressed downward bending center and plate generation is made to be bent upwards.Existing bending method is mainly deposited
In following defect：First, lower die V-groove mouth is that direct wire type contacts pressure with the plate back side, plate stress point pressure is high, due to
The far low mold of intensity and hardness of plate, is susceptible to bending trace.Second is that in order to ensure bending part surface smooth and beautiful appearance, need pair
Bending trace region is polished, and processing efficiency is not only influenced, but also the damage envelope for increasing aluminium coating into one, and it is anti-to reduce product
Corrosivity and service life.
Invention content
It being pressed to solve existing bending lower die because direct wire type contacts, plate stress point pressure is high, is also easy to produce bending trace,
Aluminum alloy part aluminium coating is destroyed, the defect in terms of product corrosion resistance, service life is influenced.The application's is designed to provide
It is a kind of can mediate contact, the Bending Mould of face formula support pressure effect and bending guard method and the metal plate bending that is consequently formed
Part solves the problems, such as that low-durometer material is also easy to produce bending trace.
A kind of Bending Mould of used in bending forming of sheet metal contains lower mold body corresponding with upper die body, the top of the lower mold body
It is V-type bending slot, it is characterised in that：There is one group of symmetrical protection board to be connected to the surface of V-type bending slot, the limit at protection board both ends
Plane is hinged on the both ends suitable position of lower mold body by connector, and protection board is allow to be fitted in the two side of V-type bending slot
On, it is equipped with multiple and V-type bending slot long round tube hole arranged in parallel, another flexible connection in the lower section of lower mold body V-type bending slot
Part is by the long round tube hole by the protection board elastic connection of V-type bending slot both sides.
The protection board is a Z-type structure being made of protection face, supporting surface and reinforcement crimp, the both ends of protection board
There are confined planes, arc connecting hole is equipped on confined planes, is equipped on the support surface oval logical with the lower section of lower mold body V-type bending slot
Hole it is corresponding multiple it is with holes.
In use, will wait for that the plate of bending is placed in protection board upper surface, pressed by upper die body, during lasting pressure testing
Protection board generates rotation with the hinge joint at both ends, while flexible connector stress is elongated, and waits for that bending plate is fitted in both sides protection
In the protection face of plate, both sides protection board realizes the guarantor of doubling bent plate material with waiting for that bending plate is fitted on the side wall of V-type bending slot
Shield acts on；When inloading part, upper die body rises, and flexible connector is shunk, and both sides protection board is generated to reversely rotate and be automatically reset, in repetition
State the progressive forming that metal plate bending can be realized in action.It is rolled over using the Bending Mould of the application and the metal plate of guard method institute bending
Comer pieces has the advantages that surface without bending impression.
The advantageous effect of the application is：
The application realizes that mediate contact force, face formula support stress bending effect using protection board isolation plate and mold；
Both having avoided mold and being directly in direct contact pressure with plate leads to surface damage, while formula support stress in face greatly alleviates plate again
Expect stress area pressure；Bending trace is can effectively avoid, mold is simple, at low cost, implementation easy to spread.

Specific implementation mode
For the ease of the smooth implementation of technical scheme, it is described in detail below in conjunction with the accompanying drawings.
The structural principle of bending lower die first, referring to attached drawing 1 to attached drawing 5, the bending of the used in bending forming of sheet metal of the application
Mold contains lower mold body corresponding with upper die body, and the top of the lower mold body 1 is V-type bending slot 5, there is one group of symmetrical protection board 2
It is connected to the surface of V-type bending slot 2, the confined planes 10 at 2 both ends of protection board are hinged on lower mold body 1 by connector stepped screw 3
Both ends threaded hole 6 in, so that protection board 2 is fitted on the two side of V-type bending slot 5, in lower mold body V-type bending slot 5
Lower section be equipped with it is multiple with V-type bending slot long round tube hole 7 arranged in parallel.Protection board 2 is one by protection face 13, supporting surface 8
With the Z-type structure for reinforcing the composition of crimp 9, there are confined planes 10 at the both ends of protection board 2, and arc connecting hole is equipped on confined planes 10
11, multiple with holes 12 corresponding with the long round tube hole 7 in lower section of lower mold body V-type bending slot are equipped on supporting surface 8.It is used in implementation
Rubber band 4 is as flexible connector by long round tube hole 7 and item with holes 12 by 2 elastic connection of protection board of V-type bending slot both sides.
In use, the plate 14 for waiting for bending is placed in 2 upper surface of protection board, pressed by upper die body 15, in lasting pressure
In the process, protection board 2 generates rotation with the hinge joint at both ends, while 4 stress of flexible connector rubber band is elongated, both sides protection board
2, with waiting for that the plate 14 of bending is fitted on the side wall of V-type bending slot 5, realize the protective effect to the plate 14 of bending；Bender
After the completion of sequence when plate inloading part, upper die body 15 rises, and flexible connector rubber band 4 is shunk, and both sides protection board 2 generates reverse rotation
It automatically resets, repeats above-mentioned action and the progressive forming to plate bending can be realized.Bending Mould using the application and protection
The metal plate bending part of method institute bending has the advantages that surface without bending impression.
It is last it should be added that；The preferred high rigidity of the used guard member of the application, high intensity, high resilient material
The sheet metal component of (such as titanium alloy, spring steel), it is ensured that stress occurs have auto restore facility under the conditions of small deformation amount；By setting
It sets and reinforces side, the purpose is to increase length direction rigidity, provide uniform surface support force effect.
