Abstract
The invention relates to a fixed-length production heating technology of a composite pipeline. According to the technology, a metal pipe die is provided; when the outer surface of the metal pipe die is coiled with a non-metal composite material, the heating temperature at two ends of the metal pipe die is higher than the heating temperature in the middle; the metal pipe die is placed on two parallel rotating rollers and is driven by a rotating mechanism to rotate on the rotating rollers; heating devices are respectively arranged beside the two rotating rollers; the densities of the heating devices arranged at two ends of the metal pipeline are greater than the density of a heating device in the middle of the metal pipe die; the heating devices and the rotating rollers are positioned on the same horizontal plane, so that the temperatures of the rotating rollers are higher than the temperature of the metal pipe die. According to the technology, the temperature of the whole composite pipeline is consistent in a production process, so that the overall performance of a final product is stable.
Description
Technical field
The present invention relates to a kind of compound pipeline complex pipeline production with fixed lengths heating process.
Background technology
Compound pipeline complex pipeline is based on metal pipe die, outside fiber and thermoplastic composite on surface wrap, shaping and produce high-strength composite pipeline.This technique mainly high-density fiber, by certain meticulous compound in cross-helicity angle, has the due mechanical property of common steel tube, have very strong decay resistance simultaneously, and cost is lower than traditional steel pipe and plastic pressure pipe.Current thermoforming pipe production all adopts impartial heated at constant temperature, and this heating employing segmentation not isothermal heating determines according to combination process particularity.In existing compound pipeline complex pipeline production technology; especially when metal pipe die outer surface is wound around nonmetallic composite; all same heating-up temperature to the temperature of metal pipe die heating along pipe die direction; then the two ends heat radiation of metal pipe die is obviously than fast in the middle part of it; adopt same heating-up temperature to whole pipeline, two ends temperature usually can be caused on the low side, employing segmentation not isothermal heating avoids the bond effect at compound pipeline complex pipeline two ends not as middle part; make whole compound pipeline complex pipeline performance inconsistent, there are differences.
Summary of the invention
The present invention is directed to above-mentioned prior art Problems existing and make improvement, namely technical problem to be solved by this invention is to provide a kind of compound pipeline complex pipeline production with fixed lengths heating process, makes compound pipeline complex pipeline production process temperature entirety identical, final products stable performance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of compound pipeline complex pipeline production with fixed lengths heating process, comprise a metal pipe die, when described metal pipe die outer surface is wound around nonmetallic composite, the heating-up temperature at its two ends is higher than the heating-up temperature at middle part.
Further, the scope at described metal pipe die two ends is that the end of metal pipe die is toward middle extension 300-500mm.
Further, described metal pipe die is placed on two transfer rollers paralleled, and ordered about by a rotating mechanism and then rotate on transfer roller, the side of described two transfer rollers is respectively arranged with heater, the heater density being arranged on metal pipe die two ends is greater than the heater density be arranged in the middle part of metal pipe die, described heater and transfer roller are in same level, to make the temperature of transfer roller higher than the temperature of metal pipe die.
Further, described heater is infrared heating device.
Further, the temperature at described metal pipe die two ends is greater than the temperature 30-50 DEG C at middle part.
Further, described nonmetallic composite is fiber or thermoplastic.
Compared with prior art, the present invention has following beneficial effect: this technique is by adding heater at metal pipe die two ends, with segmentation not isothermal heating mode, make metal pipe die outside surface wrap nonmetallic composite time, avoid pipe die end dispel the heat too fast, make whole pipe temperature consistent, there is not temperature difference, compound pipeline complex pipeline overall performance is stablized, simultaneously, the temperature of transfer roller, higher than metal pipe die temperature, makes nonmetallic composite can not be bonded on transfer roller.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the embodiment of the present invention.
In figure: 1-metal pipe die, 11-fiber, 2-transfer roller, 3-infrared heating device.
Detailed description of the invention
Embodiment one: as shown in Figure 1, a kind of compound pipeline complex pipeline production with fixed lengths heating process, comprises a metal pipe die 1, described metal pipe die 1 outside surface wrap fiber 11 time, the heating-up temperature at its two ends is higher than the heating-up temperature at middle part.
In the present embodiment, the scope at described metal pipe die 1 two ends is that the end of metal pipe die is toward middle extension 300-500mm.
In the present embodiment, described metal pipe die 1 is placed on two transfer rollers paralleled 2, and ordered about by a rotating mechanism and then rotate on transfer roller 2, described transfer roller 2 also rotates with metal pipe die 1, the side of described two transfer rollers 2 is respectively arranged with infrared heating device 3, infrared heating device 3 density being arranged on metallic conduit 1 two ends is greater than the infrared heating device density be arranged in the middle part of metal pipe die 1, described infrared heating device 3 is in same level with transfer roller 2, to make the temperature of transfer roller 2 higher than the temperature (5-20 DEG C) of metal pipe die, and then avoid fiber 11 to stick on transfer roller.
In the present embodiment, the temperature at described metal pipe die two ends is greater than the temperature 30-50 DEG C at middle part.
In the invention process one, by arranging more infrared heating device 3 at the two ends of metal pipe die, make the temperature at metal pipe die 1 two ends higher than the temperature in the middle part of it, metal pipe die 1 is under the ordering about of rotating mechanism, transfer roller 2 rotates, be arranged on infrared heating device 3 pairs of transfer rollers 2 of transfer roller 2 side, metal pipe die 1, fiber 11 heats simultaneously, because of infrared heating device 3 from metallic conduit 1 more close to, make the heating-up temperature of transfer roller 2 higher than the temperature of metal pipe die 1, and then avoid fiber 11 and be bonded on transfer roller 2, by this technique, make compound pipeline complex pipeline in process of production, when being especially wound around nonmetallic composite, stable performance, final products are made to there will not be performance difference.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
