Problems solved by technology

This results in a large number of hanging devices, increased manufacturing costs and inconvenient management
[0004] The fiber tow is limited by the wire hanging device at both ends of the mold core. The limiting device itself needs to occupy a small circumferential space and maintain a small circumferential distance, so its own strength is not high enough, and it may be bumped by careless operation. causing the needle to break

Abstract

The invention provides a combined small-angle filament winding thread-hanging device. The combined small-angle filament winding thread-hanging device comprises thread hanging needles and a thread hanging plate, wherein the outer side face of the thread hanging plate is provided with needle holes sequentially arranged in the circumferential direction. One end of each thread hanging needle is detachably arranged at the corresponding needle hole. The thread hanging plate comprises thread hanging plate frames A and thread hanging plate frames B, wherein the thread hanging plate frames A (1) and the thread hanging plate frames B (2) are connected through fixing needles, and are sequentially connected in an end-to-end mode to form a frame. The outer side face of the thread hanging plate is provided with the needle holes sequentially arranged in the circumferential direction, and filaments passing through the thread hanging needles are prevented from slippage during small-angle winding of the filaments.

Description

technical field [0001] The invention relates to fiber winding of composite materials, in particular to a combined small-angle fiber winding and hanging device. Background technique [0002] In composite filament winding products, in some cases it is required to increase the axial tensile strength of the product by reducing the angle between the fiber and the central axis. The existing winding device uses a winding machine to wind the fiber on the mandrel. Generally, this winding process can only be wound within the angle range of 30 degrees to 90 degrees. Winding at an angle that is too small will cause the fiber to slip, so it cannot Make smaller angle wraps. [0003] The wire-hanging device needs to determine its own size according to the cross-section of the product, especially for products with a regular polygonal cross-section, it is necessary to prepare a large number of wire-hanging devices of different specifications. This results in a large number of wire hanging ...
