As Fig. 4 and shown in Figure 14, the rebound 6 of present embodiment is the parts that profile is a cuboid, its cavity partly comprises taper annular domatic 22 that is positioned at upstream side and the passage 21 that is positioned at the downstream, the shape of described taper annular domatic 22 is complementary with the taper annular of the downstream of the branch fluid body 10 that stretches into this rebound 6 is domatic, and formation one is for the part of the described split channel 26 of clad material circulation between described two tapers annular is domatic, the shape of the inner peripheral surface of described passage 21 is complementary with the profile of passing the preceding inner core-body of this passage, and the size than the preceding inner core-body that passes this passage is bigger, thereby forms the part for the described split channel 26 of clad material circulation between the outer peripheral face of the inner peripheral surface of passage 21 and preceding inner core-body.As Fig. 4 and shown in Figure 15, the cylinder manifold of present embodiment also is the parts of a rectangular shape, its cavity partly comprise be positioned at upstream side domatic 24 and be positioned at the passage 23 in downstream, this shape of domatic 24 is complementary with the profile of the end of the preceding inner core-body that stretches into cylinder manifold, and form the part for the described split channel 26 of clad material circulation between the outer peripheral face of the end of described domatic and preceding inner core-body, the shape of the inner peripheral surface of described passage 23 is identical with the outer shape of aluminium alloy extrusions so that aluminium alloy extrusions moves ahead, and the big 0.1-0.5mm of sectional dimension of the aluminium alloy extrusions that the size in the cross section of this passage 23 ratio will be Overmolded.
As Fig. 4 and shown in Figure 16, the mouth template 8 of present embodiment also is the parts of a rectangular shape, and the on all four passage 25 of advancing for aluminium alloy extrusions of an inner circumferential surface shape and the appearance and size of aluminium alloy compound section bar that will be Overmolded has been offered at the position therebetween.Described die body plate, rebound, cylinder manifold, mouth template are fixedly connected sequentially together from upstream side to the downstream that section bar is advanced by the screw screw respectively.
As shown in Figure 4, inner core-body stretches out described minute fluid body 10 and passes rebound 6 and stretch among the cylinder manifold 7 before described.In the present embodiment, the size of the inner peripheral surface of described die body plate, the size of described rebound inner peripheral surface, the size of described cylinder manifold inner peripheral surface is will be respectively more bigger than the size of corresponding minute fluid body 10 and preceding inner core-body, so just at described die body plate, rebound, the inner peripheral surface of cylinder manifold and branch fluid body 10, formed the split channel 26 (the also space that can circulate for the gluey elastomer clad material of molten state) of a ring-type between the outer peripheral face of preceding inner core-body 18, described split channel 26 side is at its upstream sealed by the lug boss circlewise 28 of die body plate 4 and 5, and the outlet 30 of the split channel in its downstream (also being the outlet of clad material) is connected with the section bar outlet 27 of the downstream end of preceding inner core-body.
The coating process of aluminium alloy compound section bar of the present invention is as follows.
At first, the gluey elastomer macromolecule clad material of aluminium alloy extrusions that transports from hauling machine 1 and the molten state extruded from extruder 2 is transported to coating of the present invention with the mould 3 with synchronous speed from separately inlet, describedly be meant with synchronous speed that hauling machine is carried between the speed of section bar and the speed that extruder is carried clad material and keep certain quantitative relation, can change the thickness of the cladding material of composite material by the speed of regulating the two.
As shown in Figure 4, the section bar of being carried by hauling machine enters mould 3 from the section bar inlet 16 of back inner core-body, and under the effect of the motive force of hauling machine, constantly advance and enter preceding inner core-body, meanwhile, the gluey elastomer clad material of molten state is under the crunch effect of extruder, constantly flow into from the clad material import 15 of die body plate, enter clad material feed path 14, and enter described split channel 26 by clad material inlet 19, and under the pressure effect of extruder, in split channel 26, carry out flowing of whole 360 degree circumferentially along minute cylindrical outer surface of fluid body 10, and between the taper annular domatic 22 of domatic from all angles of whole circumferential 360 degree and taper annular that direction flows into the downstream of dividing fluid body 10 further and rebound the formed split channel section, before the gluey elastomer clad material of following described molten state further flows into again between the inner peripheral surface of the passage 21 of the outer peripheral face of inner core-body and rebound in the formed split channel section, as shown in Figure 4, because the radial dimension of the split channel section that forms between the taper annular of the downstream of the taper of rebound annular domatic 22 and branch fluid body 10 is domatic is 5mm at its upstream end, and be 3.5mm in its downstream, so constantly the gluey elastomer clad material of the molten state that flows into is compressed in the formed split channel section between domatic for the first time in that the taper annular domatic 22 of rebound and the taper that divides fluid body 10 are annular, can be through such compression so that the gap between the particle of the gluey elastomer clad material of molten state becomes littler, make clad material become more closely knit, thereby can be, and make the composite material after the machine-shaping have better physical and mechanical property so that the covered effect of composite material is better.
The gluey elastomer clad material of molten state is further advanced and is passed rebound and enter among the split channel section that forms between the taper end of domatic and preceding inner core-body of cylinder manifold then, and finally extrudes from clad material outlet 30.As shown in Figure 4, owing to have only 0.95mm in this gap that exports between the outer peripheral face of the inner peripheral surface of cylinder manifold at 30 places and preceding inner core-body end, size 3.5mm than the upstream extremity of the radial dimension of formed split channel section between the outer peripheral face of the end of the domatic and preceding inner core-body of cylinder manifold is littler, like this can be so that clad material is compressed (also compression for the second time) further by this split channel section the time, make clad material become more closely knit, further improve and coat quality, thereby finally the clad material of extruding from this outlet 30 is the clad material uniformly densely through overcompression.
Meanwhile, on the outer surface of the aluminium alloy extrusions that the described clad material of extruding from above-mentioned outlet 30 is uniformly densely just constantly advanced out along the section bar outlet 27 that circumferentially is coated on inner core-body end in the past on all angles of split channel and direction equably, and the passage 23 that described clad material is advanced further together and entered cylinder manifold along with aluminium alloy extrusions, because the cross sectional shape of the passage 23 of cylinder manifold is identical with the profile of required Overmolded composite material, just its size is than the bigger 0.1-0.5mm of size of required Overmolded composite material, like this, aluminium alloy extrusions is when advancing the passage 23 of the above-mentioned cylinder manifold of process, the cladding material that coats on its outer surface can be guaranteed homogeneous thickness by compression and typing further.
At last, after passing the passage 23 of cylinder manifold, the aluminium alloy extrusions that is coated with cladding material just is advanced in the passage 25 with the profile of required Overmolded composite material and the on all four mouth template of size, the described aluminium alloy extrusions that is coated with cladding material is further finalized the design in the passage 25 of mouth template, to guarantee needed coating thickness and shape, when described composite material was advanced out from the passage 25 of this mouth template, described aluminium alloy extrusions just coats on its outer surface to have been gone up one deck and has met the thickness of processing needs and the clad of quality.
When the described composite material export template that is coated with the macromolecule cladding material and after the mould of advancing out, as mentioned before, again through described composite material is carried out Vacuum shaping, cooling and shaping, and draw by hauling machine, carry out the detection of respective physical and mechanical performance, at last composite material be transported to the cutting with the finished product platform on cut the back just can finally obtain needed section bar in the engineering practice.
Certainly, the cross sectional shape of required Overmolded aluminium alloy extrusions is not limited to disclosed this form in the present embodiment, but can be arranged to needed various shape according to the actual needs in the engineering, in practical operation, coat the section bar of different cross section if desired, then can be and processing and manufacturing has the section bar passage that the profile with section bar is complementary and the mould of split channel according to the shape of the section bar of required coating and structure, to satisfy different needs.
Obviously, profile material of the present invention is not limited to aluminium alloy, can also be other metal material and alloy thereof, and simultaneously, described clad material also is not limited to macromolecular material, also can be other material.Die body among the present invention also can the integrally casting moulding, and without separating into die body plate, rebound, cylinder manifold and mouth template, and of the present invention minute fluid also can the integrally casting moulding, and without separating into a minute fluid body, back inner core-body, preceding inner core-body.
Above-described is the preferred embodiments of the present invention.Should be pointed out that for the person of ordinary skill of the art some distortion and the improvement made also should be considered as not exceeding protection scope of the present invention under the prerequisite that does not break away from the principle of the invention.
