Abstract
The present invention relates to a kind of compound pipeline complex pipeline production with fixed lengths heating technique, including a metal pipe die, during described metal pipe die surface wrap nonmetallic composite outside, the heating-up temperature at its two ends is higher than the heating-up temperature at middle part.Described metal pipe die is placed on two parallel transfer rollers, 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, it is arranged on the heater density at metallic conduit two ends more than being arranged on the heater density in the middle part of metal pipe die, described heater and transfer roller are in same level, so that the temperature of transfer roller is higher than the temperature of metal pipe die.This technique makes the temperature of the most whole pipeline of compound pipeline complex pipeline consistent so that final product overall performance is stable.
Description
Technical field
The present invention relates to a kind of compound pipeline complex pipeline production with fixed lengths heating technique.
Background technology
Compound pipeline complex pipeline is based on metal pipe die, outside fiber and thermoplastic composite on surface wrap, is molded and produces high-strength composite pipeline.This technique is mainly high-density fiber and is finely combined by certain cross-helicity angle, has the due mechanical property of common steel tube, has the strongest decay resistance simultaneously, and cost is less than traditional steel pipe and plastic pressure pipe.Thermoforming pipeline produces and all uses impartial heated at constant temperature at present, and this heating uses the heating of segmentation not isothermal to determine according to combination process particularity.In existing compound pipeline complex pipeline production technology; when especially metal pipe die outer surface is wound around nonmetallic composite; the temperature heating metal pipe die is all same heating-up temperature along pipe die direction; then the two ends heat radiation of metal pipe die is obviously fast than in the middle part of it; whole pipeline is used same heating-up temperature, can frequently result in two ends temperature on the low side, use the heating of segmentation not isothermal to avoid 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 problem that the present invention is directed to the existence of above-mentioned prior art makes improvement, i.e. the technical problem to be solved is to provide a kind of compound pipeline complex pipeline production with fixed lengths heating technique so that compound pipeline complex pipeline production process temperature entirety is identical, final products stable performance.
In order to solve above-mentioned technical problem, the technical scheme is that a kind of compound pipeline complex pipeline production with fixed lengths heating technique, including 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, described metal pipe die two ends extend 300-500mm in the range of the end of metal pipe die toward middle.
Further, described metal pipe die is placed on two parallel transfer rollers, 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, it is arranged on the heater density at metal pipe die two ends more than being arranged on the heater density in the middle part of metal pipe die, described heater and transfer roller are in same level, so that the temperature of transfer roller is 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 more than temperature 30-50 DEG C at middle part.
Further, described nonmetallic composite is fiber or thermoplastic.
Compared with prior art, the method have the advantages that this technique is by adding heater at metal pipe die two ends, in the way of the heating of segmentation not isothermal so that during metal pipe die surface wrap nonmetallic composite outside, it is to avoid the heat radiation of pipe die end is too fast, make whole pipe temperature consistent, there is not temperature difference so that compound pipeline complex pipeline overall performance is stable, simultaneously, the temperature of transfer roller is higher than metal pipe die temperature so that nonmetallic composite will not be bonded on transfer roller.
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
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 it is shown in figure 1, a kind of compound pipeline complex pipeline production with fixed lengths heating technique, including a metal pipe die 1, during described metal pipe die 1 surface wrap fiber 11 outside, the heating-up temperature at its two ends is higher than the heating-up temperature at middle part.
In the present embodiment, described metal pipe die 1 two ends extend 300-500mm in the range of the end of metal pipe die toward middle.
In the present embodiment, described metal pipe die 1 is placed on two parallel transfer rollers 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, it is arranged on infrared heating device 3 density at metallic conduit 1 two ends more than being arranged on the infrared heating device density in the middle part of metal pipe die 1, described infrared heating device 3 is in same level with transfer roller 2, so that the temperature of transfer roller 2 is 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 more than temperature 30-50 DEG C at middle part.
In the present invention implements 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, it is arranged on the infrared heating device 3 of transfer roller 2 side to transfer roller 2, metal pipe die 1, fiber 11 heats simultaneously, because of infrared heating device 3 from metallic conduit 1 closer to, make the heating-up temperature temperature higher than metal pipe die 1 of transfer roller 2, 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 not have performance difference.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent and modification, all should belong to the covering scope of the present invention.
