Example 1
The forming process of the thin-wall metal glued piece and the rib web of the airplane are mainly used for gluing thin-wall metal pieces such as the rib web in the airplane and sheet metal forming. The two aluminum alloy sheets are provided with the adhesive films and are adhered together, so that the fatigue strength of the aluminum alloy sheets is improved, and good sealing performance is obtained.
As shown in fig. 1 and 2, the forming process of the thin-wall metal adhesive joint provided in this embodiment mainly includes:
step S100: a plurality of flat sheet metal plates 111 are prepared.
Specifically, the corresponding metal sheet 111 may be formed by cutting according to the designed tool size of the part. The metal sheet 111 is specifically an aluminum alloy skin. In this embodiment, the metal sheet 111 may be cut into a rectangular shape, so as to facilitate the subsequent fixing of the metal sheet 111 to the tooling plate 200. While cutting the sheet metal 111 may use an automatic cutter, such as inputting the Cut size into a computer, cutting the sheet metal 111 to the corresponding size by graphic analysis software (e.g., autoCAD, etc.) and the cutter and its corresponding software (e.g., cut-Works software for GER-BER).
Preferably, the cut metal sheet 111 may be phosphoric acid anodized and primer sprayed.
Specifically, the cut metal sheet 111 is first subjected to a surface treatment to remove a natural oxide layer on the metal surface, and a new advantageous paste is formed by phosphoric acid anodizingAnd an oxide layer. In the present embodiment, the naturally occurring oxide Al of the aluminum alloy 2 O 3 -3H 2 O has poor bonding property, and oxide Al generated after phosphoric acid anodizing treatment 2 O 3 H2O, which is not prone to hydration, has good bonding durability. After the phosphoric acid anodizing treatment, a primer layer may be sprayed on the surface to be bonded of the metal sheet 111 to increase the durability and wet heat resistance of the metal bonded member in cooperation with the adhesive film 121. Meanwhile, the primer has good wettability on the metal surface, a transition layer of the metal sheet 111 and the adhesive film 121 can be formed, and the adhesive force between the adhesive film 121 and the metal sheet 111 can be effectively enhanced.
Step S200: two identical metal sheets 111 are stacked, and an adhesive film 121 is laid between the two metal sheets 111 to form a plate adhesive 110, and a plurality of plate adhesive 110 stacked to form the plate adhesive assembly 100.
In this embodiment, the plate bonding assembly 100 includes only one plate bonding member 110. Specifically, the first metal sheet, the adhesive film 121 and the second metal sheet are sequentially laid on the tooling flat plate 200 to form the flat plate adhesive member 110. The laying mode can be selected from manual laying, mechanical structure auxiliary laying, full-automatic laying and the like. In this embodiment, the metal sheet 111 and the adhesive film 121 may be sequentially laid on the tooling plate 200 by means of manual laying. On the one hand, damage to the metal sheet 111 when the metal sheet 111 is laid by the mechanical structure can be avoided, and on the other hand, the laying direction can be checked and adjusted at any time, and the metal sheet 111 is ensured to be compacted to discharge interlayer air.
Step S300: the panel glue assembly 100 is secured to the tooling panel 200 and vacuum packaged.
Specifically, the plate bonding member 110 may be fixed on the tooling plate 200 by a positioning member, a process pin, a pressure-sensitive adhesive tape, or the like, so that displacement and warpage are not generated during curing, and the bonding quality is improved. After the plate bonding member 110 is fixed, the plate bonding assembly 100 is vacuum-packed to provide a sealed vacuum system for transferring the inflation pressure of the autoclave to press the bonding structure.
Step S400: the packaged flat panel glue assembly 100 is fed into an autoclave for curing.
Specifically, the packaged panel glue assembly 100 and tooling panel 200 are fed together into an autoclave. The main material of the adhesive film 121 provided in this embodiment is a thermosetting resin. The autoclave can provide high pressure and high temperature, so that the adhesive film 121 between the metal sheets 111 can be melted and gradually hardened to be formed, i.e. the curing is completed, and the adhesive strength of the panel adhesive assembly 100 is improved.
Step S500: after the plate bonding assembly 100 after bonding is cooled to be out of the tank, the plate bonding member 110 is subjected to sheet metal forming, and the thin-wall metal bonding member is obtained.
Specifically, the cured flat panel glue assembly 100 can be removed from the autoclave after it is rapidly cooled to room temperature. And then cutting according to the design size of the workpiece, and then sending the workpiece into a die for sheet metal forming, so that the thin-wall metal glued piece can be obtained. In this embodiment, the cut flat panel gluing assembly 100 may be placed in a dedicated mold, and the desired shape is obtained by bending or stamping.
Preferably, after the cured plate adhesive 110 is removed, the excess adhesive film 121 at the edge of the plate adhesive 110 is removed.
When the flat plate bonding member 110 is laid, the size of the adhesive film 121 is slightly larger than that of the metal sheet 111, so as to ensure that the metal sheet 111 is completely bonded and cured, and avoid the situation of leakage adhesion. The excess adhesive film 121 is melted and then attached to the edge of the plate adhesive member 110, and the excess adhesive film 121 needs to be removed to repair the plate adhesive member 110.
As shown in fig. 3, the forming process of the thin-wall metal adhesive joint provided in this embodiment further includes:
step S600: nondestructive testing is carried out on the thin-wall metal glued piece after sheet metal forming, then paint spraying is carried out on the thin-wall metal glued piece, and packaging and warehousing are carried out.
In particular, in order to ensure the bonding quality of the thin-walled metal bond, nondestructive inspection of the thin-walled metal bond is required. The specific nondestructive detection can detect whether the thin-wall metal glued piece has quality problems such as surface damage, debonding, lack of glue, loosening and the like by a visual method, an illumination method, a knocking method and an acoustic vibration detection method. After the quality detection of the thin-wall metal glued joint piece is finished, the thin-wall metal glued joint piece can be sprayed with paint, so that the attractive appearance of the product is improved, and the corrosion resistance of the product is also improved. Meanwhile, the label can be marked, packaged and put in storage for use.
Through the steps S100-S600, the metal sheet 111 is glued on the tooling flat plate 200, so that the technical problems that the metal sheet 111 after sheet metal forming is difficult to position and the gap is difficult to control during gluing, so that the gluing effect is poor are avoided; meanwhile, after the metal sheet 111 is glued, the thickness of the metal sheet is increased, so that the risk of tearing of the metal sheet 111 during sheet metal forming is reduced, the technical problems of high manufacturing difficulty and low forming quality of thin-wall metal piece glued pieces such as rib webs in the prior art are relieved, the glue-joint forming of the thin-wall metal glued pieces is realized, the manufacturing cost of the thin-wall metal glued pieces is reduced, and the glue-joint performance is improved.
Further, after the panel glue assembly 100 is formed and before the panel glue assembly 110 is encapsulated, an edge stop is provided on the tooling panel 200, the edge stop is abutted against the edges of all the panel glue assemblies 110, and the height of the edge stop is higher than the height of the uppermost panel glue assembly 110.
Specifically, the number of edge stoppers may be four, which respectively abut against the four edges of the plate bonding member 110. The plate glue 110 can be fixed to the tooling plate 200. The edge stopper is higher than the uppermost flat plate adhesive 110, so that the stress concentration of the edges of the flat plate adhesive 110 due to the curing pressure of the autoclave is avoided, the pressure is decomposed onto the edge stopper, the pinch-off of the adhesive film 121 is reduced to the greatest extent, and the weak adhesive phenomenon caused by the over-thin edge film is avoided, thereby affecting the adhesive strength.
Preferably, the panel gluing assembly 100 is vacuum packaged, and specifically includes: a vacuum bag 300 is sleeved on the flat plate gluing assembly 100; sealing a gap between the vacuum bag 300 and the tooling plate 200; the interior space of the vacuum bag 300 is evacuated.
Specifically, after the plate bonding member 110 is fixed on the tooling plate 200, the vacuum bag 300 is first sleeved on the plate bonding member 110. Only sealing strips can be arranged between the vacuum bag 300 and the tooling plate 200, and gaps between the vacuum bag 300 and the tooling plate 200 can be sealed through the sealing strips. A vacuum nozzle is further provided on the vacuum bag 300, through which air in the vacuum bag 300 can be evacuated, so that a vacuum environment required for curing the plate adhesive 110 is formed, so as to press the plate adhesive 110.
Further, in step S400, the temperature of the autoclave is set to between 121 ° and 178 °.121 ° is the medium temperature in autoclave curing, 178 ° is the high temperature in autoclave curing. The curing temperature of the autoclave can be selected from 121 to 178 according to the material of the adhesive film 121, so as to achieve a better curing effect.
The invention also provides a rib web plate which is prepared and molded by the process. Therefore, the rib web has all technical effects of the molding process of the thin-wall metal adhesive joint part, and the description is omitted herein.
Example two
The forming process of the thin-wall metal adhesive part provided in this embodiment is different from the forming process of the thin-wall metal adhesive part provided in the first embodiment only in the laying manner of the flat plate adhesive part 110, and for the same parts in this embodiment and the first embodiment, the description of this embodiment is omitted.
In step S200, a plurality of the plate cements 110 are stacked to form the plate cement assembly 100, and the separation film 120 is disposed between two adjacent plate cements 110 when stacked. The isolating membrane 120 is specifically a nonporous isolating membrane, and the isolating membrane can be made of tetrafluoroethylene plastic and has the characteristics of high temperature resistance and stable chemical property. The separation of the plate bonding members 110 by the separator can prevent the two metal sheets 111 from being bonded by being heated and pressed, and can prevent the melted adhesive film 121 from penetrating between the two plate bonding members 110 to cause the plate bonding members 110 to be bonded to each other. The multi-layered panel glue assembly 100 is thereby cured together to increase production efficiency. The number of layers stacked at the same time can be automatically adjusted according to production requirements, and the operation is simple and convenient.
Further, step S500 further includes: the flat glue assembly 100 is taken out of the autoclave, the flat glue members 110 are separated from the separation film 120, and then each flat glue member 110 is sheet-metal-molded.
Specifically, after the plate bonding assembly 100 is cured, the isolating membrane 120 does not change at high temperature and high pressure of the autoclave, and the plate bonding assembly 100 can be separated into the plate bonding members 110 through the isolating membrane 120 conveniently and rapidly, and then the plate bonding members are sent into a die to be bent or stamped to finish sheet metal forming.
It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Various obvious changes, rearrangements and substitutions can be made by those skilled in the art without departing from the scope of the invention.
