Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figures 2 and 3, heater strip fixing means in a kind of fan blade iron web mold, comprises the following steps:
Step one: the connector 2 that evagination is set bottom iron web mold 1;
Step 2: lay heater strip 4 on iron web mold 1 end;
Step 3: heater strip 4 pours into insulating composite material 3, insulating composite material 3 and above-mentioned connector 2 and the adhesion of iron web mold 1 lower surface are an entirety.
Wherein, connector 2 is for being distributed on the small iron plate bottom iron web mold, small iron plate is obliquely installed, small iron plate one side and iron web mold 1 bottom welding are fixed, small iron plate opposite side tilts, bottom iron web mold 1 and between small iron plate, form angle, insulating composite material 3 injects in this angle, makes insulating composite material 3 and iron web mold 1 connection reinforcement.In step 3, insulating composite material is that glass fabric infusion epoxy resin forms, before infusion epoxy resin, first lay four-layer glass fiber cloth, four-layer glass fiber cloth can increase the rear thickness of insulating composite material solidification greatly, then priming by vacuum epoxy resin, completing steps three.
, heat conduction electric for ease of bottom iron web mold and the interval of heater strip, this method is improved as follows: after step one, before lay heater strip, first bottom iron web mold, pour into the insulating composite material layer that a thickness is no more than 3 millimeters, then repave on insulating composite material and put heater strip.
Its detailed description of the invention is as follows: insulating composite material is that glass fabric infusion epoxy resin forms, before step 2, before infusion epoxy resin, first the small iron plate welded is tilted end and upwarp to increase angle angle, facilitate glass fabric lay in subsequent step to enter; Then lay layer of glass cloth, in the angle allowing glass fabric enter to increase bottom iron web mold and between small iron plate; Subsequently oppositely beat small iron plate and tilt end, make it bottom iron web mold to reduce angle angle, now bottom iron web mold and between iron plate angular range at 2 ° ~ 15 °, preferred angular range between 3 ° ~ 8 °, thus makes small iron plate 2 and glass fabric be connected firmly after follow-up infusion epoxy resin; Subsequently lay second layer glass fabric covers all small iron plates, and second layer glass fabric plays bottom iron web mold and the interval of heater strip is electric, conductive force; Epoxide resin vacuum imports subsequently, completes perfusion insulating composite material.
As shown in Figures 2 and 3, heater strip fixed structure in a kind of fan blade iron web mold, the connector 2 of evagination is set bottom iron web mold 1, heater strip 4 is laid in iron web mold 1 end, heater strip 4 pours into insulating composite material 3, insulating composite material 3 and above-mentioned connector 2 and the adhesion of iron web mold 1 lower surface are an entirety.
Insulating composite material 3 forms for glass fabric infusion epoxy resin.Connector 2 is for being distributed on the small iron plate bottom iron web mold, small iron plate is obliquely installed, small iron plate one side and iron web mold bottom welding are fixed, small iron plate opposite side is upturned, angle is formed bottom iron web mold and between small iron plate, angular range at 2 °-15 °, preferably between 3 °-8 °; The length and width of small iron plate, thickness are 20x20x1.5 millimeter, and small iron plate row, column spacing is no more than 500 millimeters.
Feature of the present invention is: small iron plate one side and iron web mold bottom welding are fixed, small iron plate opposite side is upturned, angle is formed bottom iron web mold and between small iron plate, glass fibre reinforced plastic insulating composite layer is fed into solidification in this angle, thus the heater strip 4 bottom iron web mold 1 is not come off, and insulating composite material 3 is good with iron web mold 1 bottom adhesive, be highly resistant to that iron plate is different from insulating composite material thermal coefficient of expansion and distortion that is that cause comes off.
, heat conduction electric for ease of bottom iron web mold and the interval of heater strip, also can be perfused with thin insulating composite layer (not shown) bottom iron web mold and between heater strip.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
