Description

叶片组件模具及使用其制造叶片组件的方法Blade assembly mold and method of manufacturing blade assembly therewith 技术领域Technical field
本发明涉及风力发电领域，特别涉及一种叶片组件模具及使用其制造叶片组件的方法。The present invention relates to the field of wind power generation, and more particularly to a blade assembly mold and a method of manufacturing the same using the same.
背景技术Background technique
风力发电机叶片组件主要包括主梁、腹板和壳体，每种叶片组件都通过对应的叶片组件模具生产。主梁的生产过程主要为：主梁模具准备、辅材铺放、玻纤铺层、辅材铺放、真空***铺放、灌注固化成型和脱模。腹板的生产过程主要为：腹板模具准备、玻纤铺层、芯材铺放、玻纤铺层、辅材铺放、真空***铺放、灌注固化成型和脱模。壳体的生产过程主要为：壳体模具准备、玻纤铺层、放置主梁、芯材铺放、玻纤铺层、辅材铺放、真空***铺放、灌注固化成型，上下壳体全部完成后，需要进行腹板的粘接，粘接完成后需要对上下模壳体进行粘接，完成后进行脱模。The wind turbine blade assembly primarily includes a main beam, a web, and a casing, each of which is produced by a corresponding blade assembly mold. The main beam production process is mainly: main beam mold preparation, auxiliary material placement, glass fiber layering, auxiliary material placement, vacuum system placement, infusion solidification molding and demoulding. The production process of the web is mainly: web mold preparation, glass fiber layering, core material placement, glass fiber layering, auxiliary material placement, vacuum system placement, infusion curing molding and demoulding. The production process of the shell is mainly: shell mold preparation, glass fiber layering, placing main beam, core material placement, glass fiber layering, auxiliary material placement, vacuum system placement, infusion solidification molding, upper and lower casings. After completion, the web needs to be bonded. After the bonding is completed, the upper and lower mold shells need to be bonded, and after completion, the mold is released.
现有灌注方法需要使用欧姆管，欧姆管是一次性使用的，每次生产需要使用大量的欧姆管，浪费严重，成本较高。The existing infusion method requires the use of an ohmic tube, which is disposable, and requires a large number of ohmic tubes for each production, which is wasteful and costly.
在制造壳体时，需要大量使用欧姆管，且由于欧姆管位于玻纤铺层和导流网的上方，所以固定困难，耗时长久，严重影响生产周期。When manufacturing the housing, a large amount of ohmic tubes are required, and since the ohmic tubes are located above the glass fiber laminates and the flow guiding nets, the fixing is difficult and takes a long time, which seriously affects the production cycle.
现有灌注方法是自产品的上方向下或向侧面渗透灌注，容易出现部分产品空气难以排出，导致产品最终固化后形成树脂含胶量不足、发白、甚至干纱的缺陷，而这些缺陷对叶片来说都是致命的，维修耗时长且维修后难以达到合格产品的质量，最多只能恢复80％左右的性能。The existing infusion method is perforated from the top of the product to the side or to the side, and it is easy to occur that some of the product air is difficult to be discharged, resulting in defects in the resin containing insufficient amount of glue, whitishness or even dry yarn after the final curing of the product, and these defects are Blades are fatal, maintenance takes a long time and it is difficult to achieve the quality of qualified products after maintenance, and can only recover about 80% of the performance.
