Description

technical field [0001] The invention belongs to the field of fiber weaving and molding, and in particular relates to a carbon fiber felt pad weaving and extrusion integrated molding machine for aero-engine clamps and a method of using the same. Background technique [0002] The felt pad is an important part of the aero-engine clamp. It is installed between the hydraulic pipeline and the clamp. It plays the role of vibration damping, temperature resistance and restraint gap adjustment, and can also make the installed pipeline parts more evenly stressed. Therefore, the service life of the pipeline can be prolonged, and it has been widely used in aero-engine clamps in my country and Russia. At present, the aero-engine clamp felt is mainly woven from metal wires, but the metal material is heavy, prone to dents and cracks during extrusion, and it is easy to lose its elasticity under the large vibration excitation of the pipeline, resulting in a gradual weakening of the vibration r...

Problems solved by technology

[0003] However, the knitting machines currently on the market seldom use carbon fiber as the weaving object. Most industrial textile machines still use silk weaving cotton as the main service object. There is no carbon fiber felt pad knitting machine dedicated to aero-engine pipeline clamps. A very complete prototype machine, some existing ideas are still based on the textile industry, although the textile machine can realize the weaving of general silk, but usually can not be completely done, it is used to meet the weaving needs of rigid carbon filaments, and the general It is more difficult for the weaving machine to extrude the mat after weaving the fiber filaments

In addition, some existing weaving techniques and devices on the market also have some problems and defects. For example, a Chinese patent (publication number: CN202010350347) discloses a beating device for a loom, and a beating device is designed for a weaving machine. , using the gravity of the fiber and the spring to control the reciprocating motion of the fiber. This control method has low precision, and the weft length of the finished product is not easy to be guaranteed, resulting in the quality of the finished product.

Chinese patent (publication number: CN201910104863) discloses a loom device. The textile structure of the invention is relatively complicated, the space occupied is too large, and the matching size is large, so it is not suitable for weaving felt pads with relatively simple requirements, and the machine It can only realize the manual wire loading operation, and cannot realize automation, resulting in low weaving efficiency. At the same time, this kind of knitting machine is only designed for the knitting process, and cannot further cut, extrude and form the knitting products.

Chinese patent (publication number: CN201820644847) and Chinese patent (publication number: CN201921832430) respectively disclose a feeding device for fiber textiles and a new type of feeding device for fiber textiles, both of which are feeding devices for knitting machines , a series of mechanical structures are used to assist the wire feeding link before the knitting machine works, but all of them have the disadvantages of complex mechanism, excessive space occupation, and excessive loss of power source during work. Satisfies the wire supply demand of flat carbon fiber filaments, not suitable for weaving of flat carbon fiber mats

Chinese patent (publication number: CN201710640153) discloses a fiber textile winding processing structure. Although a new weaving method other than two-dimensional cross weaving is realized, it has high requirements on the thermal properties of the processed fiber filaments, and it is difficult to guarantee the realization Continuous weaving of carbon fiber filaments with better heat resistance

Chinese patent (publication number: CN202020764593.X) discloses an anti-winding textile machine for fabric processing, which adds an anti-winding device on the basis of traditional textile machines, but the mechanical transmission of this structure is complicated, which greatly reduces the The efficiency of the silk feeding work is reduced, and the fiber needs to go through a long span, resulting in an excessively long winding distance, which is not conducive to the carbon fiber to maintain the proper shape of the weaving, and is more suitable for traditional cotton silk weaving

Chinese patent (publication number: CN201721578469.9) discloses a textile machine that can prevent cloth breakage. The textile machine uses a yarn guide module and a weaving module on the basis of traditional textile machines, which can prevent the machine head from breaking during the textile process. The up and down movement cuts off the woven cloth. However, the machine still uses the overall movement of the machine head as the heald movement, which consumes more energy than the heald. For carbon fiber filaments, the longitudinal movement should be minimized to avoid broken wires and cloth. The patent idea cannot be well applied to the weaving of carbon fiber filaments

The Chinese patent (publication number: CN 202020299964.1) discloses a silk textile machine with the functions of tension adjustment and burr removal. The textile machine has an increased tension adjustment and burr removal structure on the basis of traditional textile machines, although it can be used during the weaving process. Remove the burrs of silk, but it is difficult to remove the burrs with ordinary knives during the weaving process of carbon fiber filaments. This method is more time-consuming in the weaving process of carbon fiber filaments, and lacks a mechanism for centralized cutting after weaving
