Description
Technical field
The invention belongs to wind electricity blade processing and manufacturing equipment technical field, more particularly to a kind of megawatt wind-power blade
The pre-embedded bolt metal flange played the role of positioning in production process.
Background technology
In wind electricity blade production process, on the pressure side (PS) and two lobe of suction side (SS) of wind electricity blade is first respectively each
From mould in carry out molding, PS sides and two split-ring mold of SS side molds are formed into blade entirety then.During matched moulds, need
Precise positioning is carried out to PS sides and SS side molds, the mode in engineering frequently with ring flange is positioned.
Existing ring flange mainly has two kinds of forms：One is double flange form, i.e., with two flanges being disposed adjacent
Disk, the fixed ring flange near inner side are used for the ring flange for positioning outside；Two is the ring flange goed deep into inside blade mold, is led to
Cross in mould root steelframe welding bending steel plate, locating flange dish.Wherein, the ring flange of the first form needs to use two pieces,
Once flange deforms, it is impossible to adjust, and increased PS side molds blade root upset weight, blade root steel frame deformation is easily caused；
The ring flange of second form causes blade root poor air-tightness, and blade root laying difficulty is big, and the blade demoulding is difficult, blade root end face plane degree
It is susceptible to skew.In addition, during the ring flange of two kinds of forms does not consider post-production demand, need to carry out pre-embedded bolt etc. to add
Work is operated so that finishing operations also need to improvement is designed under the conditions of original.
Above as can be seen that to root plane degree, early stage requires that understanding is not deep, inconsiderate is adjusted to planeness of flange, if
Congenital defect on meter, on the one hand causes blade processing precision and operating comfort to be adversely affected, on the other hand also causes
Ring flange once deforms, and adjusts extremely difficult.
