Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described.
As shown in Figure 1, after composite material parts 2 is shaping on mould 1, is closely attached to mould 1 surface, is difficult to the demoulding.Now, sealing ring 3 is positioned on composite material parts 2, then on sealing ring 3, places metallic plate 5.More preferably, described metallic plate 5 adopts steel plate, and described sealing ring 3 adopts rubber to make.Subsequently, be connected by the tapped through hole of one end of vacuum quick-release coupling 6 with metallic plate 5, the other end of vacuum quick-release coupling 6 connects vacuum tube 7, is connected to outside vacuum generating device, such as vavuum pump 8 by vacuum tube 7.After whole device connects, open vavuum pump 8 and carry out vacuum pumping, metallic plate 5 and composite material parts 2 are tightly attached together, and then pull out the positive head/cloudy head of vacuum quick-release coupling 6, the quick-release interface of vacuum quick-release coupling 6 will automatic-sealed, to maintain good vacuum.Now by applying upwards power with metallic plate 5 suspension ring that arrange of surface or handle 4, composite material parts 2 can be stripped down from mould 1.Whole process can not produce any destruction, scuffing or indentation to composite material parts 2, therefore very well ensure that the integrality of composite material parts 2.
The vacuum adsorption force that can produce stripper apparatus of the present utility model carries out following theory calculate: in one embodiment, between metallic plate 5 and composite material parts 2, vacuum area is 150mm × 150mm, vacuum is 0.8bar, then the vacuum adsorption force that 150mm × 150mm area can produce is: 0.8 × 10
5× 0.15 × 0.15=1800N.The power of 1800 Ns is a very large power, and the object that can be 183.7 kilograms (=1800/9.8) by a quality lifts.Therefore, it is economically viable for utilizing stripper apparatus of the present utility model to carry out demoulding process to composite material parts 2.
As shown in Figure 1, in another embodiment, composite material parts 2 outer surface is more coarse, uses rubber seal 3 can not make to seal completely between composite material parts 2 and metallic plate 5, now can take following method of operating.After composite material parts 2 is shaping on mould 1, is closely attached to mould 1 surface, is difficult to the demoulding.Now, rubber seal 3 is positioned on composite material parts 2, then in rubber seal 3, places metallic plate 5.Subsequently, be connected by the tapped through hole of one end of vacuum quick-release coupling 6 with metallic plate 5, connect vacuum tube 7 by the other end of vacuum quick-release coupling 6, vacuum tube 7 is connected to outside vavuum pump 8.After whole device connects, open vavuum pump 8 and carry out vacuum pumping, metallic plate 5 and composite material parts 2 are tightly attached together.Now, no longer vacuum quick-release coupling 6 is extracted the through hole in the middle of metallic plate 5, but keep vavuum pump 8 to be in the duty vacuumized always.Now by applying upwards power with metallic plate 5 suspension ring that arrange of surface or handle 4, composite material parts 2 can be stripped down from mould 1.In whole process, because vavuum pump 8 is in the duty vacuumized all the time, although therefore composite material parts 2 outer surface is more coarse, use rubber seal 3 can not make to seal completely between composite material parts 2 and metallic plate 5, but also can make to remain higher vacuum between metallic plate 5 and composite material parts 2, the vacuum of such as 0.8bar, therefore still can in whole knockout course, the very large vacuum adsorption force that all-the-time stable produces, thus successfully complete knockout course.
In some embodiment as shown in Figure 2, there will be manual afterburning situation large not, can also adopt small-sized tackles 10, lifting rope 9 through suspension ring 4, and hangs with on tackles 10, and so just can ensure that power is enough large, power distribution is appropriate.Especially suspension ring 4 are 2, and metallic plate 5 is arranged symmetrically with.Also can be that suspension ring 4 are at least 3, and metallic plate 5 is evenly arranged.More preferably, suspension ring 4 are 4, and metallic plate 5 is evenly arranged.
In some embodiment as shown in Figure 3, if product is very long, at a certain distance, multiple stripper apparatus can also be arranged, regulate the vacuum of each stripper apparatus as required, use simultaneously, carry out stripping operation.The vacuum tube 7 of each stripper apparatus is connected to respective external vacuum pump (not shown in FIG.), thus provides suitable vacuum.Then, again lifting operation is carried out to each stripper apparatus simultaneously, in the process, if composite material parts 2 smooth surface, and the vacuum that can maintain between metallic plate 5 and composite material parts 2, then can just pull out the positive head/cloudy head of vacuum quick-release coupling 6 after adopting vacuum pump evacuation to terminate, the quick-release interface of vacuum quick-release coupling 6 will automatic-sealed, to maintain good vacuum; If composite material parts 2 surface ratio is more coarse, rubber seal 3 can not keep the vacuum between metallic plate 5 and composite material parts 2 well, and vavuum pump 8 now can be kept to be in the duty vacuumized always.Make to remain higher vacuum between metallic plate 5 and composite material parts 2, and then can normally work.The size of metallic plate 5 also can need to choose according to the concrete demoulding.This stripper apparatus structure is simple, and be applicable to the knockout course of various difform composite material parts, very well ensure that the integrality of composite material parts 2, easy to operate, practicality is high, and security is good.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, art those of ordinary skill possess ken in, various change can also be made under the prerequisite not departing from the utility model aim.
