Device for replacing steel needle with Z-direction steel needle three-dimensional fabrics and buckling fibers

Abstract

The invention discloses a device for replacing a steel needle with Z-direction steel needle three-dimensional fabrics and buckling fibers. The device comprises a movable workbench, a steel needle replacing mechanism, a wire feeding mechanism, a locking mechanism, a tension control mechanism and a control system, wherein the movable workbench is driven by a servo motor, is composed of a Z-directionmovable platform and a Y-direction movable platform, and is provided with a three-dimensional fabric clamping device; the steel needle replacing mechanism drives a special clamp X to move in an X-direction through the servo motor, so that needle clamping is completed; the wire feeding mechanism drives a wire feeding needle to move in the X-direction through the servo motor, so that yarns are fedinto the three-dimensional fabrics; the locking mechanism drives a crankshaft rocking bar mechanism through a step motor to realize swinging a hook needle back and forth to complete locking; and the tension control mechanism rotates back and forth through the step motor to drive a yarn storage to move back and forth, so that yarn storage and tension control are completed. The device is compact instructure, is novel and reasonable in design, realizes automation of replacing the steel needle with Z-direction steel needle three-dimensional fabrics and buckling fibers, improves production efficiency and product consistency, is high in practicability, is good in using effect, and is convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of carbon fiber three-dimensional fabric sewing equipment, in particular to a three-dimensional fabric steel needle replacement and fiber locking device containing Z-direction steel needles. Background technique [0002] Carbon fiber three-dimensional fabric is a new type of composite material that has been born in the past two decades. It fundamentally overcomes the shortcomings of low interlayer shear strength and easy delamination of traditional laminates, and has been widely used in aviation, aerospace, military, automotive, medical and advanced sports servers and other fields. However, for a long time, three-dimensional fabrics have been weaved by hand, which makes the forming efficiency of three-dimensional fabrics low, the labor intensity is high, and the product consistency is poor. With the progress of the society and the development of the economy, the artificial weaving of three-dimensional fabri...

AI Technical Summary

Problems solved by technology

This weaving method requires two workers to work together, with high concentration, high labor intensity, low efficiency and expensive labor costs

With the progress of society and the development of economy, manual weaving of three-dimensional fabrics can no longer meet the needs of the market, and there is an urgent need for a three-dimensional fabric with Z-direction steel needle replacement and fiber locking device to complete automatic production
