A kind of wind power blade pre-embedded screw sleeve assembly, mold and production method thereof

Abstract

The invention belongs to the field of wind power generation device accessories and particularly discloses a wind power blade pre-embedded thread sleeve assembly and a mold and a production method thereof. The wind power blade pre-embedded thread sleeve assembly comprises a pre-embedded thread sleeve, two UD bars, a PET wedge and resin. The UD bars are located on the two sides of the pre-embedded thread sleeve. The PET wedge is tightly attached to the front end of the pre-embedded thread sleeve. The space among the pre-embedded thread sleeve, the UD bars and the PET wedge is filled with the resin. The wind power blade pre-embedded thread sleeve assembly and the mold and the production method thereof have the beneficial effects that firstly, the filling quality of the pre-embedded thread sleeve can be directly confirmed, and the filling combining performance of the pre-embedded thread sleeve and the UD bars can be inspected visually; secondly, independent forming is achieved, and a resin-rich area in the combined area of the thread sleeve and the UD bars is eliminated; thirdly, the staving defect of the combined area of the thread sleeve and the UD bars is eliminated; and fourth, the production cycle is shortened, work efficiency is improved, and labor intensity is relieved.

Description

technical field [0001] The invention belongs to the field of wind power generation device accessories, in particular to a wind power blade pre-embedded screw sleeve assembly, a mold and a production method thereof. Background technique [0002] In the wind power generation device, the wind power blade is a very important part, and the traditional process is to put the UD rod and the embedded screw sleeve into the embedded screw sleeve hole at the bottom of the wind power blade, and then pour it into molding, which will have the following problems : First, it is difficult to directly confirm the infusion quality of the UD yarn wrapped around the screw sleeve in the hole of the embedded screw sleeve of the wind power blade during infusion, and it is difficult to visually observe the infusion bonding performance of the embedded screw sleeve and UD rod; the second is to embed the embedded screw sleeve and UD rod The bonding area may form a resin-rich area; the third is that ther...
