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, solidify assisted heating device after relating in particular to a kind of matched moulds that is used for wind power generation blade production.
Background technology
In the blade design at present, the overwhelming majority is to adopt glass fiber reinforced epoxy resin as its main material, and uses epoxy adhesive bonding, and the back curing quality of epoxy resin and adhesive has decisive influence for product quality.
When adhesive reached basic curing performance, Tg (glass transition temperature) was approximately more than 65 ℃.Existing adhesive is after solidifying 4 hours after 70 ℃, and Tg has just reached requirement.Along with the time increases, the Tg value is increasing.
But the back solidification process of following the tracks of existing blade can be seen, finishes up to heating schedule, and the Tg of product does not reach requirement far away yet.
Looking into its reason, mainly is because of the not enough institute of the temperature in the blade extremely.Though program temperature just reaches 75 ℃ at 90min; And insulation is also above 8 hours; But in fact blade root just reaches maximum temperature up to heating after 2 and a half hours, and keeping warm mode also has only 4 hours, the most important thing is that maximum temperature also rises less than 75 ℃; As long as about 65 ℃, do not reach requirement far away.Only in leading edge near the local heating rate of heating than very fast, maximum temperature is than higher, this possibly be because here relatively near the thermal treatment zone, and blade relatively small property give birth to.Zone on other place, especially the butt web is impossible meet the demands at the Tg of that region samples under existing condition.
Therefore, in the solidification process of back, 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 having provided a kind of matched moulds that is used for wind power generation blade production, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention includes: the air-heater that is placed in web butt place; Described air-heater connects first heating tube, second heating tube and the 3rd heating tube; Described first heating tube, second heating tube and the 3rd heating tube pass the hole of the butt baffle plate that is placed on the web butt; First heating tube is at web butt rear, and the front end of first heating tube is apart from 0.9 meter-1.1 meters of web butt; Second heating tube is above the web butt, and the front end of second heating tube is apart from 5 meters-7 meters of web butt; The 3rd heating tube is below the web butt, and the front end of the 3rd heating tube is apart from 2 meters-3 meters of web butt.
Compared with prior art, the invention has the beneficial effects as follows: reach under the constant situation of mold temperature, still can be issued to the effect of curing in the short period, rear curing time can shorten to 7.5 hours by present 8.5 hours.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a butt baffle arrangement sketch map.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Visible by Fig. 1, Fig. 2: as to the present invention includes: the air-heater 1 that is placed in web A butt place; Described air-heater 1 connects first heating tube 2, second heating tube 3 and the 3rd heating tube 4; Described first heating tube 2, second heating tube 3 and the 3rd heating tube 4 pass the hole 6 of the butt baffle plate 5 that is placed on web A butt; First heating tube 2 is at web A butt rear, and the front end of first heating tube 2 is apart from 0.9 meter-1.1 meters of web A butt; Second heating tube 3 is above web A butt, and the front end of second heating tube 3 is apart from 5 meters-7 meters 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-3 meters of web A butt.
The present invention is used for placing butt baffle plate, air-heater and the airduct that adds warm-air pipe.
Add warm-air pipe and be divided into 3 sections, put into trailing edge respectively apart from 5 to 7 meters of butt, blade root is apart from 1 meter of butt, and blade inlet edge is apart from 2 to 3 meters of butt.
The present invention is because the mode that adopts assistant heating is solidified after to blade heats, and reaches under the constant situation of mold temperature, and still better the short period is descended the effect of curing.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 following:
, main mould matched moulds behind the bound edge, adds warm-air pipe, particular location such as Fig. 1 in having pasted in the mould inside layout.Behind the hole of the butt baffle plate of airduct through being placed on the web butt, be connected with the air-heater at web butt place.
Open air-heater, when web butt place temperature surpasses 90 ℃, closed air-heater 5 minutes 1 hour heat time heating time, continue then to open, finish until heat time heating time.
