Technical Field

The invention relates to a wind power blade core material processing tool.

Background

In the production process of the wind power blade, in order to enable the bonding between the web plate and the blade shell to be tighter, (the defect of rich resin is reduced by the web plate shell and the flange, and the bonding strength between the web plate and the blade shell is increased), a triangular bar is generally used for filling an irregular gap between the web plate and the flange, and then resin glue is used for bonding. The traditional triangular bar processing is limited by the material thickness, the processing efficiency and other reasons, and only 90-degree triangular bars with uniform styles can be processed. However, the angle of the web plate rib follows the shape of the inner cavity of the blade shell, the angle of the web plate rib is changed frequently, and if the uniform triangular bars are used as stuffing transition, stress concentration, product defects, resin waste and other adverse effects can be caused, and the production cost and the product quality of the web plate are directly influenced. Although the multi-angle triangular bars can also be produced, the production efficiency is low, the quality is not well controlled, and the production efficiency of the blades is directly influenced.

Disclosure of Invention

The invention aims to overcome the defect that multi-angle triangular bars used for filling gaps between webs and blade shells are difficult to process in the prior art, and provides a wind power blade core material processing tool capable of solving the problems.

The invention solves the technical problems through the following technical scheme:

the utility model provides a wind-powered electricity generation blade core processing frock which characterized in that, it includes:

the guide strip is internally provided with a rhombic channel which extends along the axial direction and is communicated;

the base plate is a flat plate, the periphery of the guide strip is axially fixed on the base plate, and a plane formed by the upper edge and the lower edge of the rhombic channel is perpendicular to the base plate.

Preferably, one end of the guide bar is provided with a guide groove, the guide groove extends along the prismatic channel, a plane formed by an upper edge and a lower edge of the prismatic channel is equally divided into the guide groove, and the guide groove penetrates through the substrate and the guide bar along the vertical direction.

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Fig. 1 shows a wind turbine blade core material processing tool, which includes: guide bars 100 and a base plate 200. The guide strip 100 has a diamond-shaped passage 110 extending axially therethrough. The base plate 200 is a flat plate, the outer circumference of the guide bar 100 is fixed on the base plate 200 along the axial direction, and the plane formed by the upper edge and the lower edge of the rhombic channel 110 is perpendicular to the base plate 200. In the embodiment in the market, the guide strip is a rhombic strip and is coaxial with the rhombic channel.

When the core material is processed into the triangular strips with different angles by using the tool, firstly, the plate is cut into strip-shaped core materials by using a cutting machine, and the size of the core materials is matched with that of the rhombic channel 110. The substrate 200 of the processing tool is fixed on a processing table, a band saw for cutting the core material is opposite to one end of the rhombic channel 110, the core material is plugged into the rhombic channel 110 from the other end of the rhombic channel 110 and is cut into two parts by the band saw, and the two completely symmetrical triangular strips are cut. The inside of the inlet end of the rhombic passage 110 is provided with an arc chamfer, which is convenient for plugging a core material into the rhombic passage 110. For the triangular strips with different angle requirements, only the processing tools with different angles need to be prefabricated. The tool can cut the core material efficiently with high quality to form the triangular strips with different angle requirements, the requirement of filling the gap between the web and the blade shell is met, the production efficiency is improved, and the labor cost is reduced.

In order to ensure that the band saw can accurately cut the diamond-shaped core material into two symmetrical triangular strips during cutting, one end of the guide strip 100 is provided with a guide groove 120, the guide groove 120 extends along a prismatic channel, a plane formed by the upper edge and the lower edge of the rhombic channel 110 is equally divided into the guide groove 120, and the guide groove 120 penetrates through the substrate 200 and the guide strip 100 in the vertical direction. In actual processing, the core material may be cut after the band saw is aligned with the diamond-shaped channel 110 in position and angle through the guide groove 120, or the core material may be cut by placing the direct band saw in the guide groove 120. In order to ensure the accuracy of the guiding, the depth of the guide groove 120 is not less than 5 cm.

As shown in fig. 2, the bottom surface of the substrate 200 has an adhesive layer 300 to ensure that the tool does not move during the processing. The adhesive layer 300 in this embodiment is a glass glue that is easy to remove. Considering that the curing rate of the glass paste is relatively slow, the hot melt adhesive stick is generally used to fix both sides of the substrate 200 on the processing table.

Triangular bars with different sizes and angles are needed for filling different wind power blades, and in order to avoid the situation that an operator takes the tooling by mistake, the angles and the sizes of the rhombic channels 110 are marked on the outer surface of the guide bar 100.

In this scheme, gib block 100 and base plate 200 are printed by engineering plastics 3D and are formed. 3D prints and has the low price, makes simply, and the material is light, safe characteristics.

Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
