Abstract
The invention discloses an outside reinforcing, vacuum filling and heat curing molding process on the front edge and back edge of a blade. The process comprises the following steps of: firstly laying glass fiber cloth at reinforcing parts on the front edge and back edge of the blade, and then performing vacuum filling and heating curing molding. By performing vacuum filling for outside reinforcement of the front edge and back edge of the blade, the quality defects of reinforcement layering, bubbles, adhesive fillets and the like on the front edge and back edge of the blade can be greatly reduced, and the reliability of the blade is improved; and simultaneously, the curing of resin can be accelerated by curing after heating, and the production efficiency is improved.
Description
Technical field
The present invention relates to the outer reinforcement priming by vacuum heat cure moulding process of a kind of blade front and rear edge.
Background technology
Wind electricity blade is the key position of the effective capturing wind energy of wind power generating set, the outer reinforcement of traditional wind electricity blade front and rear edge be all with glass-fiber-fabric with resin impregnated after, hand is stuck with paste the reinforcement position, then by spontaneous curing, reaches the purpose of outer reinforcement.Because hand paste glass-fiber-fabric has the mass defects such as layering, bubble, glue knurl, reduced greatly the reliability of blade.Simultaneously, the spontaneous curing time is longer, has reduced the production efficiency of blade.
Summary of the invention
For above-mentioned weak point of the prior art, the present invention aims to provide the outer reinforcement priming by vacuum heat cure moulding process of a kind of blade front and rear edge, the mass defects such as blade front and rear edge reinforcement layering, bubble, glue knurl have been greatly reduced, improved the reliability of blade, simultaneously, reduced the blade production time.
In order to achieve the above object, technical scheme of the present invention: the outer reinforcement priming by vacuum heat cure moulding process of a kind of blade front and rear edge, the step of its technique is, first strengthen the position at the blade front and rear edge and carry out glass fiber cloth laying, and then priming by vacuum, moulding is heating and curing.
Further, before described glass-fiber-fabric carries out laying, strengthen the laying shape at position according to the blade front and rear edge and carry out cutting.
Before the blade front and rear edge is strengthened the position and carried out glass fiber cloth laying, tear the release cloth at this reinforcements position, and adopt the acetone wipe surfaces to clear up.
The step of described priming by vacuum is, lays successively release cloth, flow-guiding screen on glass-fiber-fabric, at flow-guiding screen edge laying injected rubber hose, lays the vacuum bag film in the superiors, vacuumizes at last, pours into.
Described being heating and curing solidified after heating blanket heats for laying on the surface.
At last, after curing, heating blanket, vacuum bag film, flow-guiding screen, injected rubber hose are removed.
Beneficial effect of the present invention: priming by vacuum is carried out in the outer reinforcement of blade front and rear edge, can reduce greatly the mass defects such as blade front and rear edge reinforcement layering, bubble, glue knurl, improve the reliability of blade, simultaneously, after heating, curing can be accelerated resin solidification, has improved production efficiency.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the FB(flow block) of moulding process of the present invention.
The specific embodiment
Further describe the present invention below in conjunction with specific embodiment and accompanying drawing.
The outer reinforcement priming by vacuum heat cure moulding process of a kind of blade front and rear edge as shown in Figure 1, the step of its technique be, first strengthen the position at the blade front and rear edge and carry out glass fiber cloth laying, and then priming by vacuum, moulding is heating and curing.
The present invention mainly adopts the technique of priming by vacuum heat cure to replace traditional hand and sticks with paste the resin mode to the outer reinforcement operation of blade front and rear edge, this technique can reduce the mass defects such as blade front and rear edge reinforcement layering, bubble, glue knurl greatly, improve the reliability of blade, heat cure simultaneously can be accelerated resin solidification, has improved Leaf productivity.
Before described glass-fiber-fabric carries out laying, strengthen the laying shape at position according to the blade front and rear edge and carry out cutting, this cutting glass-fiber-fabric size can be carried out cutting according to concrete production technology; And the laying of glass-fiber-fabric also can be carried out laying according to concrete specification requirement specification and mode.
What emphasize is, before the blade front and rear edge is strengthened the position and carried out glass fiber cloth laying, tears the release cloth at this reinforcements position, and adopts acetone wipe surfaces and near zone thereof to clear up, with the quality of raising resin priming by vacuum and follow-up use service life.
Step for priming by vacuum is, lays successively release cloth, flow-guiding screen on glass-fiber-fabric, at flow-guiding screen edge laying injected rubber hose, lays the vacuum bag film in the superiors, vacuumizes at last, pours into.Afterwards, described being heating and curing solidified after heating blanket heats for laying on the surface.After cured the auxiliary material of vacuum of laying before heating blanket, vacuum bag film, flow-guiding screen, injected rubber hose etc. is removed complete stand-by getting final product.
The above technical scheme that the embodiment of the present invention is provided is described in detail, used specific case herein principle and the embodiment of the embodiment of the present invention are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the present invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the present invention, all will change on the specific embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
