Abstract
The invention relates to an auxiliary heating device for the post-curing of a die assembly for wind turbine blade production, comprising an air heater arranged at the root end of a web plate; the air heater is connected with a first heating pipe, a second heating pipe and a third heating pipe; the first heating pipe, the second heating pipe and the third heating pipe pass through an opening of a root end baffle arranged at the root end of the web plate; the first heating pipe is arranged at the rear of the root end of the web plate, and the front end of the first heating pipe is 0.9-1.1m away from the root end of the web plate; the second heating pipe is arranged above the root end of the web plate, and the front end of the second heating pipe is 5-7m away from the root end of the web plate; and the third heating pipe is arranged below the root end of the web plate, and the front end of the third heating pipe is 2-3m away from the root end of the web plate. The auxiliary heating device has the beneficial effects that a curing effect can still be achieved within shorter time under the condition that the die temperature is not changed, and the post-curing time can be shortened from 8.5h at present to 7.5h.
Description
Technical field
The present invention relates to a kind of heater, relate in particular to a kind of for solidifying assisted heating device after the matched moulds of wind power generation blade production.
Background technology
In blade design, the overwhelming majority is to adopt glass fiber reinforced epoxy resin as its main material, and uses epoxy adhesive bonding at present, and the rear curing quality of epoxy resin and adhesive has conclusive impact for product quality.
When adhesive reaches basic curing performance, Tg (glass transition temperature) is approximately more than 65 DEG C.Existing adhesive solidified after 4 hours after 70 DEG C, and Tg has just reached requirement.Along with the time increases, Tg value is increasing.
Can see but follow the tracks of existing vaned rear solidification process, until heating schedule finishes, the Tg of product is also far not by far up to the mark.
Looking into its reason, is mainly because of the inadequate institute of the temperature in blade extremely.Although program temperature just reaches 75 DEG C at 90min, and insulation also exceedes 8 hours, but in fact blade root is until heating just reached maximum temperature after 2 and a half hours, keeping warm mode also only has 4 hours, the most important thing is that maximum temperature also rises less than 75 DEG C, as long as 65 DEG C of left and right, are far not by far up to the mark.Only in leading edge near the local heating rate of heating than very fast, maximum temperature is higher, this may be due to here relatively near the thermal treatment zone, and blade relatively small property is raw.Region on other place, especially butt web is impossible meet the demands at the Tg of that region samples under existing condition.
Therefore,, in rear solidification process, blade root is necessary to design a kind of firing equipment to realize the raising of the blade efficiency of heating surface.
Summary of the invention
The technical issues that need to address of the present invention are solidified assisted heating device after being to provide a kind of matched moulds of producing for wind power generation blade, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: the air-heater that is placed in web butt place; Described air-heater connects the first heating tube, the second heating tube and the 3rd heating tube; Described the first heating tube, the second heating tube and the 3rd heating tube passes the hole of the butt baffle plate that is placed on web butt; The first heating tube is at web butt rear, and the front end of the first heating tube is apart from 0.9 meter of-1.1 meters of of web butt; The second heating tube is above web butt, and the front end of the second heating tube is apart from 5 meters of-7 meters of of web butt; The 3rd heating tube is below web butt, and the front end of the 3rd heating tube is apart from 2 meters of-3 meters of of web butt.
Compared with prior art, the invention has the beneficial effects as follows: reach in the situation that mold temperature is constant, still can be issued to curing effect in the short period, rear curing time can shorten to 7.5 hours by present 8.5 hours.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is butt baffle arrangement schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
From Fig. 1, Fig. 2: the present invention includes: the air-heater 1 that is placed in web A butt place; Described air-heater 1 connects the first heating tube 2, the second heating tube 3 and the 3rd heating tube 4; Described the first heating tube 2, the second heating tube 3 and the 3rd heating tube 4 passes the hole 6 of the butt baffle plate 5 that is placed on web A butt; The first heating tube 2 is at web A butt rear, and the front end of the first heating tube 2 is apart from 0.9 meter of-1.1 meters of of web A butt; The second heating tube 3 is above web A butt, and the front end of the second heating tube 3 is apart from 5 meters of-7 meters of of web A butt; The 3rd heating tube 4 is below web A butt, and the front end of the 3rd heating tube 4 is apart from 2 meters of-3 meters of of web A butt.
The present invention is used for placing the butt baffle plate, air-heater and the airduct that add warm-air pipe.
Add warm-air pipe and be divided into 3 sections, put into respectively trailing edge apart from 5 to 7 meters of of butt, blade root is apart from 1 meter of of butt, and blade inlet edge is apart from 2 to 3 meters of of butt.
The present invention heats owing to solidifying after adopting the mode of auxiliary heating to blade, reaches in the situation that mold temperature is constant, still better curing effect under the short period.Rear curing time can shorten to 7.5 hours by present 8.5 hours.
The present invention is simple to operate, easy to use, and can adjust its heating region and time according to actual conditions.
Operating process of the present invention is as follows:
Pasted after interior bound edge at main mould matched moulds, arranged and add warm-air pipe at mould inside, particular location is as Fig. 1.Airduct, by being placed on behind the hole of butt baffle plate of web butt, is connected with the air-heater at web butt place.
Open air-heater, 1 hour heat time, in the time that web butt place temperature exceedes 90 DEG C, close air-heater 5 minutes, then continue to open, until the heat time finishes.
