Description

A kind of blade of wind-driven generator mould

Technical field

The utility model relates to and is applied to the blade of wind-driven generator mould manufacturing field, is a kind of blade of wind-driven generator mould.

Background technology

At present, all wind electricity blades all are to adopt unitary mould to produce in the world, this die size is big, weight is big, for security consideration, countries in the world railway, highway administration department all are conditional to the length that carries cargo, height etc., cause mould transportation difficulty, increased cost of transportation.Simultaneously, because unitary mould is big owing to the stress contraction distortion in application process, it is stable that the dimensional accuracy of blade profile can not keep; And the blade mold enormous size, making needs to provide big relatively mould making space in the blade mold manufacture process, higher to the production space requirement, causes the waste of space resources, does not meet megatrend, influences product promotion.

The utility model content

The purpose of this utility model provides a kind of blade of wind-driven generator mould, has overcome that the said goods size is big, weight is big, and transportation is inconvenient, the deficiency that cost is high.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of blade of wind-driven generator mould, comprise segmented die and composite set, described two adjacent groups segmented die connects by composite set, described composite set mainly is made up of mold frame, compoboard, side connecting plate and fastening bolt, the mold frame both sides at adjacent sectional die assembly place are installed two groups of side connecting plates respectively, and side connecting plate passes through the fastening bolt interlocking on mold frame; Welding two compoboards that are tightly connected on the mold frame, the junction of mold frame and compoboard is provided with stiffener; Described two compoboards connect by alignment pin, and alignment pin is set on two compoboards, and alignment pin is near place, two ends difference socket positioning sleeve, and two positioning sleeves are separately positioned on two compoboard both sides, and the alignment pin threaded one end connects locking nut; Insert and put sealing strip in the middle of described two compoboards.

Described compoboard one end passes through to strengthen the shop layer and connects a leaf model, and leaf model curing is connected on the mold frame, and the leaf model surface is provided with repair layer, covering and heat insulating cover layer on the leaf model.

The beneficial effect of blade of wind-driven generator mould described in the utility model is: utilize present technique that large mold is decomposed, not only easy to use, also solved the transportation difficult problem of strange land mfg. moulding die, reduce produce, cost of transportation; When producing the blade of different size, some group section of mould can be shared, reduced the manufacturing cost of mould; Can prevent the radially distortion of stress generation of mould after some cover compoboards are installed in the mould, guarantee the blade profile geometric accuracy, help improving the quality of products; Save the mould making space, reduce space requirement, help product promotion.
