Problems solved by technology

[0002] At present, the known vacuum bag molding process is extensive, but in the past vacuum bag molding process, there are traces of diversion tubes on the surface of the product. The higher the vacuum pressure, the deeper the traces of the diversion tube. After forming, secondary processing is required to repair the traces left when the diversion tube is filled with resin, which requires a lot of grinding and repairing, which has a great impact on workers' working hours and working environment

Embodiment Construction

[0027] As shown in the figure, the vacuum bag pressure non-marking forming process of glass fiber reinforced plastic parts of wind power generating set is characterized in that it includes the following steps,

[0028] Step 1: Wrap the diversion tube 1 with the diversion net 2, sew the diversion net 2 together with the textile thread 3, and fix the diversion tube 1;

[0029] Step 2, connecting the diversion net 2 with the product felting diversion net 4;

[0030] Step 3: When the vacuum bag film absorbs the vacuum, use the vacuum bag film to wrap the diversion tube 1 and lift it up, so that the distance between the diversion tube 1 and the product blanketing diversion net 4 is 30mm to 50mm, and the diversion net 2 and the product felt guide flownet4 stay connected;

[0031] Step 4, use the guide tube 1 to pour resin into the material;

[0032] Step 5. After the product is demolded, the glass fiber reinforced plastic part product of the wind power generating set is obtained. ...

Abstract

The invention relates to a vacuum bag traceless pressing molding process and a vacuum bag traceless pressing molding device of a wind generating set glass fiber reinforced plastic part, and belongs to the technical field of wind power generation. The process comprises the steps: wrapping a guide pipe by adopting a guide net, and suturing the guide net by utilizing a spinning thread for fixing; enabling the guide pipe to be 30mm to 50mm away from a product felted guide net, and maintaining the connection between the guide net and the product felted guide net; and discharging and demolding to obtain the product. The vacuum bag traceless pressing molding device comprises the guide pipe, the guide net, the spinning thread and the product felted guide net; the guide net wraps the guide pipe, the guide net is sutured by virtue of the spinning thread, and the guide net is connected with the product felted guide net. Compared with the prior art, the vacuum traceless pressing molding process and the vacuum bag traceless pressing molding device have the characteristics of no vacuum bag pressing molding trace, low cost, high efficiency and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a vacuum bag pressure non-mark forming process and equipment thereof. Background technique [0002] At present, the known vacuum bag molding process is extensive, but in the past vacuum bag molding process, there are traces of diversion tubes on the surface of the product. The higher the vacuum pressure, the deeper the traces of the diversion tube. After forming, secondary processing is required to repair the traces left when the diversion tube is filled with resin, requiring a lot of grinding and repairing, which has a great impact on workers' working hours and working environment. [0003] Therefore, a kind of new technology is badly needed in this field to change this status quo. Contents of the invention [0004] The technical problem to be solved by the present invention: aiming at the deficiencies and defects of the prior art, the present invent...
