Abstract
The utility model discloses a solidification equipment behind hollow section bar of pultrusion combined material. Including air heater, pipeline, centre form, external mold and tractor, a serial communication port, the air heater passes through the pipe connection centre form, and the centre form has cup jointed the external mold outward, the tractor will soak the resin under tensile force fibre passes through the space between external mold and the centre form to heat -curing forms the product. The hollow structure of hollow pultrusion section bar is utilized to this scheme, has designed a back solidification equipment. Because the length of pultrusion section bar can very long (can reach 10m's the order of magnitude), a curing time can be very long after the institute, is greater than the curing time in the mould far away. Back curing time t=10m400mmmin=25min is calculated to pultrusion speed according to conventional 400mmmin. If need longer back curing time, it can only to need to prolong pultrusion section bar length.
Description
Technical field:
The utility model relates to a kind of pultrusion composite materials hollow profile Post RDBMS device.
Background technology:
As everyone knows, pultrusion molding process is by the continuous fiber of impregnating resin glue, band, cloth or felt etc., by mould extruding, solidification under tractive force effect, and a kind of moulding process of the composite material section bar that successive production length is not limit; Be suitable for the glass fiber reinforced plastic shapes producing various section form, as pipe, rod, solid profile (I shape, grooved, square) and hollow section (door-window section bar, blade) etc., there is the advantages such as product properties is stable, production efficiency is high, fiber content is high, cost is lower, be widely used.
For polymer matrix composites, the curing degree of its matrix resin is higher, and mechanical property, the electrical property of goods are better.The content of monomer such as meanwhile, the curing degree of resin is higher, styrene residual in product are lower, and the styrene discharge in use procedure is less, is favourable to environmental protection.
For pultrusion molding process, due to the restriction by process conditions, the hardening time of pultrusion product is general shorter, and its curing degree is often difficult to reach higher level.Pultrusion is determined by following formula hardening time:
t＝S/v
T: pultrusion hardening time
S: die length
V: pultrusion speed
Ordinary circumstance, pultrusion die about length 1000mm, about speed 400mm/min, then can calculate pultrusion t=1000/400=2.5min hardening time.
Under so short hardening time, the curing degree of pultrusion product is not high, generally needs to carry out Post RDBMS process.Usually, be by product complete for production and processing, be deposited in baking oven and heat a period of time, or naturally stack a period of time, improve curing degree.Naturally stack process, reduce production efficiency; The process of baking oven heating Post RDBMS not only needs to increase a lot of investment, also wastes the more energy.
Utility model content:
In view of above-mentioned technical problem, the utility model provides a kind of pultrusion composite materials hollow profile Post RDBMS device.The program utilizes the hollow-core construction of hollow drawing and extruding section bar, devises a kind of Post RDBMS device.Because the length of drawing and extruding section bar can very long (can reach the order of magnitude of 10m), so rear curing time can be very long, be far longer than the hardening time in mould.The pultrusion speed of 400mm/min calculates routinely, rear curing time t=10m/400mm/min=25min.As rear curing time that need be longer, only need to extend drawing and extruding section bar length.
Concrete technical scheme of the present utility model is as follows:
Pultrusion composite materials hollow profile Post RDBMS device, comprises air-heater, pipeline, internal mold, external mold and hauling machine; It is characterized in that, described air-heater connects internal mold by pipeline, is socketed with external mold outside internal mold; Described hauling machine will impregnated of the fiber of resin by the space between external mold and internal mold under a stretching force, and the formation product that is heating and curing.
In such scheme, the hot air temperature of described air-heater is 50-250 DEG C.
The utility model, by hollow drawing and extruding section bar core, in type drawing and extruding section bar internal cavities, passes into hot-air, maintains the air themperature of mould outlet to cast-cutting saw portioned product internal cavities, thus heats this section of product, impel its abundant Post RDBMS.Pass into the temperature of hot-air, controlled by external air-heater.
In addition, adopt hot-air heated mode, the enrichment of drawing and extruding section bar internal cavities styrene can be prevented, solve the product quality flaw caused because of styrene enrichment.
Accompanying drawing illustrates:
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is pultrusion composite materials hollow profile Post RDBMS device schematic diagram.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, the utility model, when reality uses, will impregnated of the fiber 5 of resin, under the pulling force effect of hauling machine 7, by the space between external mold 1 and internal mold 2, be heating and curing and will form product 6.
The hot-air that air-heater 4 produces, by being connected to the pipeline 3 on the centre bore of internal mold 2, is blown into the cavity in the middle of in type product 6.Hot-air continuous heating, from mould outlet to the product of cast-cutting saw part, makes it continue Post RDBMS, improves the curing degree of product.
It is pointed out that this Post RDBMS device in addition, take hot-air as heating carrier.The action space being simultaneously hot-air with pultrusion composite materials hollow profile product therein cavity.Hot-air is produced by external air-heater.Hot air temperature is 50-250 DEG C.Pultrusion composite materials hollow profile, refers to the fibre-reinforced composite that is matrix with unsaturated polyester resin, vinylite, polyurethane resin, epoxy resin, phenolic resins and transformed lines show thereof such as the glass fibre, carbon fiber, aramid fiber etc. that adopt pultrusion molding process to manufacture.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
