Abstract
The utility model discloses a connecting structure of a sectional type blade die. Die connecting flanges are arranged at joints of subsections of the blade die and are abutted and fastened through bolts, an adhering groove is formed at the abutted part of every two die connecting flanges, and an adhesive layer is arranged in each adhering groove; and steel frame connecting flanges are arranged at abutted parts of die steel frames fixed on the blade die and are also fastened and connected by using bolts. The connecting structure of the sectional type blade die, disclosed by the utility model, has the advantages of simple structure, simplicity and convenience in operation, convenience in installation and stable performance, and can be used for achieving the aim of sectional manufacture and installation of a large wind turbine blade die and reducing the manufacturing cost of the blade die.
Description
Technical field
The utility model relates to a kind of syndeton of fan blade, particularly a kind of syndeton of sectional-type blade mould.
Background technology
Great development along with wind-force, the wind field development of resources starts to turn to low wind speed wind field, longer to the requirement of blade with the megawatt blower fan, during blade design, blade profile is extended in the blade tip section, and the molded line of root area is not made change, therefore, blade mold can be made to the segmentation form, combine different segmented dies by replacing and carry out the blade upgrading.How to design syndeton and the method for connection segment mould and incite somebody to action head it off effectively.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, provides a kind of simple in structure, easy and simple to handle, is convenient to install the syndeton of the segmented wind wheel blade mould of stable performance.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of syndeton of sectional-type blade mould, be characterized in: the segmentation joint at blade mold is provided with the mould adpting flange, the mould adpting flange docks fastening by bolt, at the joint of mould adpting flange, be provided with bonding groove, in bonding groove, is provided with bond layer; The mould steelframe joint be fixed on blade mold also is provided with the steelframe adpting flange, and the steelframe adpting flange also is bolted connection.
In the syndeton of sectional-type blade mould described in the utility model: described bond layer is preferably the polyurethane material layer, also can use the adhesives that similarly has high bonding, high tenacity.
The method of attachment of the syndeton of the utility model sectional-type blade mould is: at first in blade mold segmentation place, by designing requirement, make the formpiston of segmentation, and make the mould adpting flange, and reserve bonding groove at mould adpting flange joint; Simultaneously, make the steelframe adpting flange on the mould steelframe; During connection, use theodolite adjusting vane mould absolute altitude position, inject bonding agent to bonding groove inner high voltage vacuum and form bond layer; Re-use bolt tightening mould adpting flange; After the bond layer curing molding, the mould steelframe is fixed on blade mold, and uses bolt tightening steelframe adpting flange.
Compared with prior art, the syndeton of the utility model sectional-type blade mould has simple in structure, easy and simple to handle, be convenient to install, the advantage of stable performance, it can realize the segmentation manufacture of large-scale wind wheel blade mould, the target of installation, reduces the cost that blade mold is made.
The accompanying drawing explanation.
A kind of schematic diagram that Fig. 1 is the utility model syndeton.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
