Embodiment Construction

[0058] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0059] Such as figure 1 Shown, a kind of forming method of main beam of blade, it comprises the following steps:

[0060] Step 100, sequentially laying the first-level reinforcing material layer, release cloth and diversion net on the blade main beam mold, and performing the first vacuum infusion molding to form a semi-formed blade main beam;

[0061] Step 101, placing the semi-formed blade main beam in the blade main formwork shell;

[0062] Step 102, laying a continuous felt in the blade main form shell;

[0063] Step 103, pressing the main beam of the semi-formed blade on the continuous mat;

[0064] Step 104, laying a second-level reinforcement material layer above the semi-formed blade main beam, and sequentially laying a third-level reinforcement material layer, release cloth and flow guide net on the blade main formw...

Abstract

The invention discloses a forming method for a blade main beam. The forming method comprises the following steps of: sequentially paving a primary reinforcing material layer, de-molding cloth and a diversion net on a blade main beam mould to perform primary vacuum filling forming, thereby forming a semi-formed blade main beam; putting the semi-formed blade main beam into a blade main mould shell; and paving a secondary reinforcing material layer above the semi-formed blade main beam, and sequentially paving a tertiary reinforcing material layer, de-molding cloth and a diversion net on the blade main mould shell to perform secondary vacuum filling forming. According to the forming method disclosed by the invention, the blade main beam with large megawatt stage and a relatively great reinforcing material layer is formed in twice, so that the local cloth layer wrapping problem of the blade main beam is solved, and forming quality of the blade main beam is improved, and therefore, quality of the blade is improved.

Description

technical field [0001] The invention relates to a forming method of a main beam of a blade, in particular to a forming method of a main beam of a blade which solves the enveloping of the main beam. Background technique [0002] Wind power blades above 2MW are the key components of high-power wind turbines required for wind power development. At present, both at home and abroad are developing towards high-power and large-size wind power blades. However, due to the limitations of process materials and research and development capabilities, most of the wind turbines entering commercial applications are below 1.5MW. The main girder is the key component of blade production. In the past, the main girder of blades below 1.5MW was formed at one time. However, the 2MW main girder has a thicker layer and a larger width, making it difficult to form at one time. [0003] If the 2MW main girder adopts one-time molding, due to the different flow rates of the upper and lower resins in the...
