Description

Carbon fiber felt pad weaving and extruding integrated forming machine for aircraft engine hoop and using method of carbon fiber felt pad weaving and extruding integrated forming machine
Technical Field
The invention belongs to the field of fiber weaving and forming, and particularly relates to a carbon fiber felt pad weaving and extruding integrated forming machine for an aircraft engine hoop and a using method of the carbon fiber felt pad weaving and extruding integrated forming machine.
Background
The felt pad is an important component of the clamp of the aero-engine, is arranged between a hydraulic pipeline and the clamp, plays the roles of vibration reduction, temperature resistance and restriction gap adjustment, and can enable the installed pipeline piece to be stressed more uniformly, so that the service life of the pipeline can be prolonged, and the felt pad is widely applied to the clamp of the aero-engine in China and Russian. At present, the clamp felt pad of the aero-engine is mainly woven by metal wires, but metal materials are heavy in mass and prone to dent and crack during extrusion forming, elasticity is removed easily under the large-amplitude vibration excitation of a pipeline, vibration reduction effect is weakened gradually, and the thrust-weight ratio and fuel economy are improved without using an advanced aero-engine. The carbon fiber has the outstanding advantages of high specific modulus, high specific strength, high temperature resistance, good corrosion resistance and the like, and if the carbon fiber can be woven into a felt pad structure in the hoop, the carbon fiber can replace a metal felt pad to play a better role, and has a wider application prospect in the field of aeroengines.
However, at present, most of the commercial knitting machines use carbon fiber yarn as a knitting object, most of the industrial knitting machines still use silk-woven cotton yarn as a main service object, no perfect prototype machine exists for the carbon fiber felt knitting machine special for the aircraft engine pipeline hoop, some of the existing concepts are still based on the textile industry, although the textile machine can realize the weaving of common silk yarn, the existing concepts cannot be completely met under the normal condition, the carbon fiber felt knitting machine is used for meeting the knitting requirement of carbon fiber yarn with strong rigidity, and the common knitting machines are more difficult to realize the extrusion molding function of the felt cushion knitted by the fiber yarn. In addition, some weaving techniques and devices available on the market have some problems and defects, for example, chinese patent (publication number: CN202010350347) discloses a beating-up device of a loom, which is designed for a weaving machine, and uses the gravity of the fiber and a spring to control the fiber to reciprocate, so that the control mode has low precision, and the weft length of the woven finished product is not easy to be ensured, thereby causing the quality of the processed finished product to be not over-qualified. Chinese patent (publication No. CN201910104863) discloses a loom device, which is complex in textile structure, too large in occupied space size, large in fit size, not suitable for weaving a felt cushion with relatively simple requirements, and the loom can only realize manual yarn-assembling operation, and cannot realize automation, so that the weaving efficiency is low. Chinese patent (publication number: CN201820644847) and Chinese patent (publication number: CN201921832430) respectively disclose a feeding device for fiber spinning and a novel feeding device for fiber spinning, which are both feeding devices for a braiding machine, and a series of mechanical structures are adopted to assist the yarn feeding link before the braiding machine works, but the feeding devices have the defects of complex mechanism, overlarge occupied space and overlarge loss of an applied power source in the work process, have too harsh requirements on feeding, cannot meet the yarn feeding requirement of flat carbon fiber yarns, and are not suitable for braiding flat carbon fiber felt mats. Chinese patent (publication No. CN201710640153) discloses a winding processing structure for textile fibers, which realizes a novel weaving method other than two-dimensional cross weaving, but has high requirements for the thermal properties of processed filaments, and it is difficult to ensure the continuous weaving of carbon filaments with good heat resistance. Chinese patent (publication No. cn202020764593.x) discloses an anti-winding textile machine for processing cloth, which is added with an anti-winding device on the basis of a traditional textile machine, but the structure has complex mechanical transmission, greatly reduces the efficiency of yarn supply work, and the fiber yarn needs to pass through a longer span, so that the winding distance is overlong, the carbon fiber is not beneficial to maintaining the due shape of the weaving, and the anti-winding textile machine is more suitable for the traditional cotton yarn weaving. Chinese patent (publication No. CN201721578469.9) discloses a cloth-breakage-preventing textile machine, which adopts a yarn guide module and a weaving module on the basis of a conventional textile machine, and can prevent the vertical movement of a machine head during the textile process from cutting off the woven cloth, however, the machine still uses the whole movement of the machine head as the comprehensive movement, and is more energy-consuming than a heddle, and the longitudinal movement of the carbon fiber yarn should be reduced as much as possible to avoid the yarn breakage and the cloth breakage. Chinese patent (publication No. CN 202020299964.1) discloses a silk weaving machine with tension adjustment and burr removal functions, which is added with a structure of tension adjustment and burr removal on the basis of a traditional weaving machine, although burr of silk can be removed in the weaving process, it is difficult to remove burr of carbon fiber yarn by using a common cutter in the weaving process, and this method is more time-consuming in the weaving process of carbon fiber yarn and lacks a mechanism for centralized cutting after weaving.
