Fig. 2 illustrates a forming method of a console support arm according to an embodiment of the present invention, including:
s101: a mold is prepared.
The invention adopts a molding mode to prepare the display and control console support arm. The mould comprises an upper mould and a lower mould so as to facilitate the attachment of the carbon fiber composite material.
The carbon fiber composite material used in the invention belongs to a material capable of being cured by heating, has the advantages of high specific strength and specific rigidity, corrosion resistance and light weight, and can be widely applied to the fields of aerospace, marine equipment and the like.
S102: the first film and the second film are respectively laid on the inner walls of the upper die and the lower die.
The first film and the second film are made of the carbon fiber prepreg. Cutting into proper size, and spreading onto the inner walls of the upper and lower dies.
Alternatively, the first film of the present invention may have a first bonding portion, and the second film may have a second bonding portion. The first combining part and the second combining part are matched in shape. After the mold is closed, the first combining part is contacted with the second combining part. The first film and the second film are respectively provided with the joint parts, so that the convenient and fast die assembly is facilitated.
Optionally, the first and second bonds are formed from carbon fibre prepregs. The prepreg can be deformed randomly before curing, and the first bonding part and the second bonding part can be tightly attached together after die assembly. And the prepreg can be well bonded together after being heated.
S103: and paving an air pipe in the lower die paved with the second film, and then closing the die with the upper die paved with the first film.
FIG. 3 illustrates an air duct used in an embodiment of the present invention. The air duct 100 has an air charging port 101, an air detection port 102, and a body 103. Wherein the shape of the body 103 is the same as that of the display and control console support arm, and the whole body can be enlarged by 1.3 to 1.5 times in proportion.
Alternatively, before the mold is closed, the upper mold and the lower mold are spaced apart by a predetermined distance, and then the upper mold is moved until the first joining portion and the second joining portion contact each other. Therefore, the accuracy of mold closing can be ensured.
The display and control console support arm has the special-shaped closed cavity, so that the surface of the display and control console support arm can be convex and/or concave. At this time, the inner wall of the upper mold and/or the lower mold also has protrusions and/or depressions, respectively, as shown in fig. 4. At the moment, fillers can be filled at the raised and/or sunken corners before die assembly, so that the fillers can prevent the air pipe from being erected when high-pressure air is subsequently introduced, and finally formed finished products are deformed. Optionally, the filler used is solid silica gel.
In the embodiment shown in fig. 4, the upper mold 200 has the depression 210, the lower mold 300 has the protrusion 310, and the first and second films 400 and 500 are laid on the inner walls of the upper and lower molds 200 and 300, respectively. The corners of the protrusion 310 and the recess 210 are filled with the filler 600.
Optionally, the air duct used in the present invention is a nylon air duct. The nylon air pipe can bear high pressure.
Because high-pressure gas is introduced subsequently, in order to ensure that the upper die and the lower die can be stably connected together, the upper die and the lower die are optionally closed and fastened in a mode of locking the flanges by bolts. Of course, other connection or clamping modes can be adopted in other embodiments of the invention.
S104: after the die is closed, high-pressure gas is introduced into the air pipe, so that the first film and the second film are respectively attached to the upper die and the lower die.
Under the action of the high-pressure gas, the first combination part of the first film and the second combination part of the second film can be attached together.
Alternatively, the high pressure gas used in the present invention is high pressure nitrogen. The nitrogen is safe and cheap, and the process cost can be reduced.
Too little pressure of the high-pressure gas increases product porosity and reduces product performance, and too much pressure may cause deformation of the mold or separation of the upper and lower molds. Alternatively, the pressure of nitrogen gas may be set to 0.4MPa to 1 MPa.
S105: and after high-pressure gas is introduced, heating and curing the first film and the second film to form and combine the first film and the second film together.
Optionally, the whole mold after the high-pressure gas is introduced is placed into an oven for heating and curing. The use cost of the equipment can be reduced by using an oven for curing.
S106: and removing the upper die and the lower die.
I.e. demolded. And demolding to obtain the display and control console support arm made of the carbon fiber composite material.
Optionally, the first and second films are trimmed together after demolding.
The forming method of the display and control console support arm provided by the invention can shorten the process flow and improve the forming efficiency. But also can control the risk of glue joint cracking and increase the stability of the product.
The invention further provides a display and control console support arm manufactured by the method. The arm has little risk of splitting and is very stable.
It should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
