Abstract

The invention relates to the field of wind power generation, in particular to a preparation die and a preparation method for a fan blade root and the root of a fan blade. The preparation die comprisesa die body and a bush, wherein a first groove is formed in the die body, and the bush is provided with a second groove; the bush can be matched with or separated from the die body; when the bush andthe die body are separated, the first groove is a processing groove; when the bush is matched with the die body, the second groove is a processing groove; the first groove is larger than the second groove. The preparation method for the fan blade root comprises the following steps of placing a flange tool in the processing groove of the preparation die of the fan blade root; arranging an outer skin layer group, a bolt sleeve, a wedge block and an inner skin layer group in the processing groove; and carrying out filling. The preparation die can be used for preparing the fan blade roots of different dimensions, so that the die opening cost is lowered favorably.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a mold for preparing fan blade root, a preparation method and the fan blade root. Background technique [0002] At present, the fan blades are usually formed by vacuum infusion, and the upstream and downstream surfaces are respectively poured, and then the two halves of the shell are bonded together. hub connection. [0003] Generally, the length of the fan blade is closely related to its weight. The longer the fan blade, the greater the weight of the blade. When the weight of the fan blade increases, the flange diameter of the blade root needs to be increased to strengthen the connection between the fan blade root and The load strength of the fan main body connection. [0004] However, the molds provided by the related art for preparing wind turbine blade roots can only be used to prepare blade roots of one size, resulting in the need to prepare molds of different sizes in...
