Description
Technical field
The utility model relates to a kind of heater, particularly a kind of heater that is applicable to fan blade girder, web former mould.
Background technology
In recent years, along with the growth of wind-driven generator pool-size, the size of pneumatic equipment blades made increases thereupon, and the quality of fan blade is had higher requirement.The factor that influences the fibre glass product manufacture quality is more; Except the advanced degree of operating personnel's total quality, former and the method for manufacturing technology; Most important is exactly the quality of mould; Because the control of the temperature of resin solidification is most important, so be exactly heating system than part and parcel in the mould.Present stage, most fan blades mainly adopted housing, girder and web structure, and its middle shell provides aerodynamic configuration and bears the part shear-type load; Girder is born most of bending load in fan blade, have the strength and stiffness that improve blade, prevents the effect of local buckling; Shear web can be resisted the load of shearing force in the on-plane surface, so girder and web play critical role in fan blade.And the qualitative factor that influences girder and web most important be exactly the quality of its mould.The former mould of producing fan blade is divided into main former and auxilliary former, and main former is used for making blade shell, and auxilliary former mainly comprises girder former and web former, is used for producing girder and web.Good former mould requires to have excellent sealing performance and smooth operating surface and stable heating system.Wherein stable heating system is a very important step, and it directly influences performance of products.In the existing technology, what the auxilliary former of fan blade generally adopted is electric heating system.Though electrical heating has the advantage of quick heating in practical application, himself there are a lot of shortcomings.1), lack reliability mainly show:, temperature is wayward, and heating rate is inhomogeneous during intensification, is prone to the too high phenomenon of local temperature; 2), the easy oxidation of resistance wire in prolonged and repeated use, when circuit goes wrong, whole heating system be difficult to the maintenance; Possibly bring unsafe factor to production; Electrical heating heat loss in addition is big, and non-uniform temperature, the situation that causes mould to damage because of hot-spot possibly occur; Cause mould to lose efficacy, have a strong impact on production efficiency.3), have when having a power failure suddenly, the temperature of electric heating system disappears, and has brought inconvenience to practical operation, has increased difficulty for the control of blade technical process.4) in case, the electric heating system short circuit, at first to investigate out off position, secondly trouble will push the external structure of mould aside and repair, the repairing mould workload is big, it is long to take the mould effective time.
Summary of the invention
The utility model technical problem to be solved is that the temperature brought of the electric heating system to prior art is uneven, and the deficiency of difficult control of temperature provides that a kind of structure is more reasonable, the heater of the uniform fan blade girder of heating-up temperature and web former.
The utility model technical problem to be solved is that the technical scheme through the following stated also realizes.The heater of a kind of fan blade girder and web former is characterized in: it comprises oil heater and the thermal conductive material layer that is located on the inner structure layer of former, and the pre-buried oil circuit that is provided with in thermal conductive material layer, described oil circuit circulate with oil heater and be communicated with.
In the described heater technical scheme of the utility model, optimized technical scheme is:
1, is interval with the lightweight material between the described oil circuit.Like this, can alleviate the weight of former effectively.The preferred cork wood of described lightweight material.Also can use other light material.
2, the preferred die heater of described oil heater can be realized better heating control like this.
3, it also is provided with oily supplies, and described oily supplies is communicated with oil heater through pipeline.Like this, can in oil circuit, replenish conduction oil as required easily.
4, described thermal conductive material layer can be mixed and made into by aluminium powder, aluminum shot and epoxy resin, and the gross weight of aluminium powder and aluminum shot and the weight ratio of epoxy resin are 1:1.3～7, and wherein the weight ratio of aluminium powder and aluminum shot is 1:8～9; The fineness of described aluminium powder is preferably 40～100 orders, and the particle diameter of aluminum shot is preferably 1～5mm.
The oil circuit of the utility model device is located at and forms circulating oil path in the mould, is provided with preferably evenly, and mold temperature is even in the time of can making heating like this.Because the thermal conductivity of aluminium powder is better, density is low.Aluminium powder aluminum shot and resin mix with the quality proportioning of the best and form mixture as thermal conductive material layer, have so both reached the intensity of heat-conducting layer, the own wt of mould alleviates, and the while is also satisfied the instructions for use of heat conduction.But make oil heater through preferred die heater and can realize the speech reading interface operation; Temperature, resin curing process variation of temperature and the control of time of recycle oil in accurate reflection more directly perceived and the control mould; Simultaneously can be according to producing required temperature of regulating recycle oil in the mould at any time, flexible operation and practical.And the conduction oil coefficient of heat conduction in the oil pipe is bigger, and thermal conductivity is good in heating systems, and is lower to the pressurized class requirement of firing equipment, can reduce the cost of heating system; And heat-carrying agent can be recycled, and the temperature of the circulatory system adopts intelligent control, is not prone to the situation that mould burns out.Therefore adopt oily heat cycles to have higher security.
The utility model device can be under lower operating pressure (less than 0.5Mpa); Obtain higher operating temperature (≤320 ℃), reduced pressurized grade with hot equipment, can be according to the manufacturing technique requirent of reality; Mould is carried out the setting of different temperatures and heat time heating time to different resin solidification systems; And can pass through the embedded program setting of computer, the maximum temperature warning system is set, and can passes through visualization interface; At any time monitoring temperature and change of time have realized that temperature actuated is easier, flexible in the security that improves system.The adjusting of heating-up temperature can be adopted Based Intelligent Control, and temperature-controlled precision height≤± 1 ℃ can satisfy the strict demand of high technology standard.The utility model device volume is little, takes up an area of fewly, get final product near being installed in mould, need not ad hoc boiler room, need not the special messenger and operates, and can reduce equipment investment and operating cost; Even have a power failure suddenly, mould can not have temperature at once yet, has solved this accident greatly, greatly reduces financial cost, has prolonged the service life of mould, makes that the production process technology of product is more effective to have obtained execution; Blade critical component quality is guaranteed, thereby has effectively prolonged the service life of fan blade.
Compared with prior art, the utility model heater is satisfying the mould intensification simultaneously faster, and it is even to have satisfied mold temperature; Make the temperature of mould more easy to control, it is convenient to have brought to actual production; Heater is not fragile, greatly reduces financial cost, has prolonged the service life of mould, and is safe and reliable.
