Abstract
The invention discloses a kind of laying methods of wind electricity blade core material, are laid with layer of plastic film on the fabric, and core material is placed in mold on the plastic film of loose position, pull plastic film, and core material is driven to move to predeterminated position from the loose position of mold together.The present invention effectively solves the problem of the fold and destruction that caused core material damage core surfaces and die surface fabric generate in prior art core material laid course, and this method implementing process is reliable, and clear process greatly improves the quality of production.
Description
Technical field
The present invention relates to production equipment fields, and in particular to a kind of laying method of wind electricity blade core material.
Background technique
China is the country of energy shortages, develops the core that new energy, especially application have Chinese independent intellectual property right
Technology, greatly developing wind-power electricity generation more becomes one of the main strategic of Chinese energy.Including bone from the structure of fan blade
Frame and core material, currently, the sandwich material for composite material sandwich structure mainly has: rigid foam, honeycomb and cork wood three classes.
In particular with the emergence of world's renewable energy wind-powered electricity generation industry, it is worth the structural foam core material of wind power blade main material substantially
It is promoted.In fan blade manufacturing process, core material need to be cut into certain shape, to meet the requirement of technique.Under normal conditions, core material
Shape be the triangle at right angle or be on one side bevel edge right-angled trapezium.At present during laying, directly core material is driven in
Mold, or core material is directly promoted into mold.If directly driving in mold, since core material compressive strength is lower, core material is easily damaged, is led
Cause maintenance.If core material is directly promoted mold, easily cause fabric crease defect, cause to repair, and until product stripping it
It is preceding all to find.
Summary of the invention
In order to overcome the problems, such as the damage of core material caused by blade core material laid course and fabric crease, the present invention provides one
The laying method of kind wind electricity blade core material.
In order to achieve the above objectives, technical scheme is as follows:
A kind of laying method of wind electricity blade core material, specifically includes the following steps:
A, core material cutting is spliced into the entirety being adapted with die size；
B, die surface is covered with fabric, is laid with layer of plastic film on the fabric；
C, core material is placed in mold on the plastic film of loose position；
D, plastic film is pulled, core material is driven to move to predeterminated position from the loose position of mold together.
Preferably, in step D, when plastic film and core material being pulled to move together, core material has artificial at the uniform velocity push to cooperate, directly
Core material is extremely moved into predeterminated position.
Through the above technical solutions, the beneficial effect that the present invention obtains is: the present invention effectively solves prior art core material
The problem of caused core material damage in laid course, the fold and destruction of core surfaces and the generation of die surface fabric, this method
Implementing process is reliable, and clear process greatly improves the quality of production.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
One embodiment of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of the laying method of wind electricity blade core material disclosed in the embodiment of the present invention.
Corresponding component title represented by number in figure:
1. 2. core material of mold.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Below with reference to embodiment and specific embodiment, the present invention is described in further detail.
Embodiment
As shown in Figure 1, a kind of laying method of wind electricity blade core material, specifically includes the following steps:
A, core material 2 is cut and is spliced into the entirety being adapted with 1 size of mold；
B, 1 surface of mold is covered with fabric, is laid with layer of plastic film on the fabric；
C, core material 2 is placed in mold 1 on the plastic film of loose position；
D, plastic film is pulled, core material 2 is driven to move to predeterminated position from the loose position of mold 1 together.
In step D, when plastic film and core material 2 being pulled to move together, core material 2 has artificial at the uniform velocity push to cooperate, until will
Core material 3 moves to predeterminated position.At this time due to having layer of plastic film effect among the fabric and mold 1 on 2 surface of core material, avoid
The outer surface of core material 2 and the friction of mold 1 outer surface fabric, substantially increase the quality of product.
Above-described is only a kind of laying method of wind electricity blade core material of the present invention, it is noted that for this field
For those of ordinary skill, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these
Belong to protection scope of the present invention.
