Abstract

The invention relates to a variable-section polygonal woven mandrel which is characterized by comprising a mandrel shaft, wherein a long groove is formed in the mandrel shaft, the long groove extends to the bottom end surface of the mandrel shaft from the top of the mandrel shaft along with the length direction of the mandrel shaft, so as to form a through groove end, a plurality of mandrel rings are sheathed outside the mandrel shaft and are arranged along with the length direction of the mandrel shaft, bulges matched with the long groove are arranged on the inner ring surface of each mandrel ring, a catch lever matched with the long groove is arranged between the bulges of two adjacent mandrel rings, the locking catch lever and the mandrel shaft are fixedly connected, N positioning levers are evenly distributed on the outer peripheral surface of each mandrel ring circumferentially, N is more than or equal to 3, and a cover body component is supported by the positioning levers. According to another technical scheme, the invention provides an assembling method of the variable-section polygonal woven mandrel. By adopting the technical scheme, the advantages are as follows: 1. the structure is simple, the weight is light, and the universality is strong; and 2. the manufacturing is easy, and the mandrel withdrawal is convenient and consumes less time.

Description

technical field [0001] The invention relates to a weaving mandrel and an assembly method thereof, in particular to a variable-section polygonal weaving mandrel and an assembling method thereof, belonging to the technical field of textiles. Background technique [0002] The knitting machine has excellent profiling knitting ability, relying on the mandrel to weave preforms of different shapes, which can meet the requirements of mechanical properties of military, aerospace and other composite materials. The profiling knitting ability of the knitting machine depends on the mandrel. On the premise of ensuring the external size and shape of the mandrel, it is an urgent problem to be solved to reduce the weight of the mandrel and reduce the difficulty of drawing the braided parts. Contents of the invention [0003] The technical problem to be solved by the present invention is: the existing mandrel is heavy, difficult and time-consuming to pull out the mold. [0004] In order to...
