A glass fiber cloth scribing tool for wind power blade mold

Abstract

The invention provides a glass fabric scribing tool for a wind power vane mold. The tool comprises a scribing assembly for scribing a glass fabric at the position of a vane tip of the mold, a moving assembly for driving the scribing assembly to move in the axial direction of the mold and a reference assembly for ensuring that the distance between the scribing assembly and a rear edge parting surface of the mold is kept fixed when the scribing assembly conducts scribing, the scribing assembly, the moving assembly and the reference assembly are sequentially connected, and the moving assembly isdisposed on the upper surface of a mold flange; the reference assembly is in limiting cooperation with the side face of the mold flange. The glass fabric scribing tool for the wind power vane mold hasthe advantages of being high in scribing accuracy, convenient to operate, simple in structure and the like.

Description

technical field [0001] The invention relates to the field of wind power blades, in particular to a glass fiber cloth scribing tool for a wind power blade mold. Background technique [0002] Wind turbine blades are usually infused into blade molds. Before the infusion molding of wind power blades, glass fiber cloth needs to be laid on the inner surface of the mold to meet the stiffness requirements of the blades after molding and ensure the mechanical properties of the blades. Since the mold is located at the tip of the blade as a narrow curved surface section, it is difficult to position the glass fiber cloth at the trailing edge of the blade tip during the layup process, and it is impossible to use a nesting material for laying, usually after the laying of the glass fiber cloth is completed. Dash crop. [0003] The existing glass fiber cloth scribe line cutting method is to use a tape measure to measure the position and mark points every 1m, and then connect each mark poi...

AI Technical Summary

Problems solved by technology

This method is cumbersome to operate and has high labor intensity, and the marking time from the trailing edge of the mold 30m to the tip of the blade is about one hour, which takes a long time and has low work efficiency; There are operational errors in the point marking and the connection of the marking points, which makes the marking accuracy low and cannot guarantee the cutting accuracy of the glass fiber cloth, resulting in the uneven size of each layer of glass fiber cloth from the parting line of the rear edge of the mold, resulting in mold clamping interference. Phenomena such as excessive thickness of the trailing edge affect the processing quality and service life of wind turbine blades
