The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 to Fig. 4, bound edge manufacture craft in lower house 6 leading edges comprises the steps: (1) moulding upper shell 1 in mold 2 on the wind power generation blade of the present invention; (2) will carry out resin prepreg and moisten the inwall that the interior bound edge layer of cloth of handling 3 is adhesively fixed on upper shell 1; (3) bonding vacuum bag film 5 between the shearing ribs 4 of upper shell 1 inwall and upper shell 1; (4) moulding lower house 6 in bed die 7; (5) with mold 2 and bed die 7 matched moulds, and with 8 sealings of the seam of the matched moulds between upper shell 1 and the lower house 6; (6) confined space that last lower house 6 is formed vacuumizes, and carries out the inwall of interior bound edge layer of cloth 3 and upper shell 1, lower house 6 bonding through vacuum pressure.
Wherein, step (1), (2), (3) are the operations that upper shell 1 is carried out, and are referred to as first process; Step (4) is the operation that lower house 6 is carried out, and is referred to as second process; Step (5), (6) are the operations that last lower house 6 is carried out simultaneously, are referred to as the 3rd process.Fig. 2 to Fig. 4 corresponds respectively to the sketch map of each process.
