Abstract
The present invention discloses a metal felt and a manufacturing process thereof. The metal felt is characterize in that the metal felt has plural layers of metal wire transverse layers, plural layers of metal wire longitudinal layers are arranged between the metal wire transverse layers, and the upper surface, the lower surface and the outer surface of the metal felt can be provided with protection coatings. The process steps comprise that: (1) a metal wire is wound on a plate-like tire to form a helical spring with a certain inner diameter, and the helical spring is wound on the plate-like tire a plurality of layers; and (2) the wound helical spring-like blank is cut according to the required size, and a flat-shaped cushion is pressed and processed on a stamping mold. According to the present invention, the metal felt is subjected to double-crossing winding so as to provide characteristics of sufficient strength, acid corrosion resistance, alkali corrosion resistance, high temperature resistance, low linear thermal expansion coefficient and good and reliable performance metal, and is a metal felt used for fastening fixation of pipelines and lines of aero-engines. In addition, the manufacturing process of the metal felt is provided.
Description
Technical field
The present invention relates to a kind of metal felt and the manufacturing process thereof of the fastening fixing use of pipeline, the circuit of aero-engine.
Background technology
Metal felt is widely used in, on the pipeline, line system of engine in Aeronautics and Astronautics industry, pipeline, circuit being played to fastening fixation.In these industries, high to properties of product requirement, to the material of product, intensity, the performance requirements such as structure are higher, and non-other products can substitute.General product is in the time of these industry applications, and selecting of clip liner is improper, does not reach the requirement of appointment, and in some special environment, the material of common product cannot meet its requirement.Traditional liner is generally rubber or wire netting, so its intensity, performance can not meet Aeronautics and Astronautics standard.Tradition rubber blanket material oil resistant, acid-alkali-corrosive-resisting, resistance to elevated temperatures are poor, cannot use for some particular surroundings; Tradition rubber blanket abrasion resistance properties is poor, and service life can not be permanent; Rubber blanket expanded by heating is also relatively large, uses in some special dimensions again.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of metal felt of research and design and manufacturing process thereof, poor in order to solve existing metal felt abrasion resistance properties, service life can not be permanent; Rubber blanket expanded by heating is also relatively large, the shortcoming using in some special dimensions again.The technological means that the present invention adopts is as follows:
A kind of metal felt, is characterized in that comprising: wire transverse layers and wire longitudinal layer; Described metal felt is provided with multiple layer metal silk transverse layers; Between described wire transverse layers, be provided with multiple layer metal silk longitudinal layer.
The wire that can be 1Cr18Ni9Ti material as preferred described wire transverse layers and wire longitudinal layer is made.
Can be provided with protective coating as the upper and lower outer surface of preferred described metal felt.
As being provided with stiffener between preferred described wire transverse layers.
A kind of metal felt manufacturing process, is characterized in that comprising following processing step:
(1) wire made from 1Cr18Ni9Ti material one is enclosed to the helical spring that is wound in certain internal diameter on tabular shape tire, helical spring is wound around multilayer on tabular shape tire, every layer along horizontal and vertical direction cross winding, when winding between the every circle of helical spring continuously every;
(2) the coil spring shape blank winding size is as requested cut off, in diel, press process goes out flat-shaped liner.
As between the every circle of helical spring being wound described in preferably continuously every.
Compared with the prior art, metal felt intersection secondary of the present invention is wound around, for the manufacture of 1Cr18Ni9Ti material metal silk forms, and its intensity foot, acid-alkali-corrosive-resisting, resistance to very high temperature, thermal linear expansion coefficient is low, functional and reliable metal felt.Can be applied to acid and alkali resistance, oil resistant, in resistant to elevated temperatures environment, can in 500 DEG C of hot environments, work for a long time, and material thermal expansion coefficient is low, and anti-wear performance is good, and shock resistance is strong.Long service life, reduces maintenance and repair expense.Metal felt point of the present invention is welded on clip, after clip inner liner metal felt, with pipeline, the laminating degree of circuit is better, not only be suitable for the fastening fixing of conventional pipeline, circuit, and meet pipeline, circuit fastening fixing of engine in Aeronautics and Astronautics industry, and can ensure that clip can bear powerful vibration and the high temperature of aircraft, improve security and the fastening fixing reliability of clip.
Brief description of the drawings
Fig. 1 is blank structural representation after first step processing of the present invention.
Fig. 2 is metal felt structural representation of the present invention.
Detailed description of the invention
As shown in Figure 2, a kind of metal felt, is characterized in that comprising embodiment 1: wire transverse layers 1 and wire longitudinal layer 2; Described metal felt is provided with multiple layer metal silk transverse layers 1; Between described wire transverse layers 1, be provided with multiple layer metal silk longitudinal layer 2, make described metal felt have elasticity, shock resistance is strong.Described wire transverse layers 1 and wire longitudinal layer 2 can be that the wire of 1Cr18Ni9Ti material is made, acid-alkali-corrosive-resisting, and resistance to very high temperature, thermal linear expansion coefficient is low.The upper and lower outer surface of described metal felt can be provided with protective coating 4, once adds its wearability.Between described wire transverse layers 1, can be provided with stiffener 3, make its intensity stronger.
As depicted in figs. 1 and 2, a kind of metal felt manufacturing process, is characterized in that comprising following processing step:
(1) wire made from 1Cr18Ni9Ti material one is enclosed to the helical spring that is wound in certain internal diameter on tabular shape tire, helical spring is wound around multilayer on tabular shape tire, every layer along horizontal and vertical direction cross winding, when winding between the every circle of helical spring continuously every.
(2) the coil spring shape blank winding size is as requested cut off, in diel, press process goes out flat-shaped liner.
Between the every circle of the described helical spring being wound continuously every.
Metal felt intersection secondary of the present invention is wound around, for the manufacture of 1Cr18Ni9Ti material metal silk forms, and its intensity foot, acid-alkali-corrosive-resisting, resistance to very high temperature, thermal linear expansion coefficient is low, functional and reliable metal felt.Can be applied to acid and alkali resistance, oil resistant, in resistant to elevated temperatures environment, can in 500 DEG C of hot environments, work for a long time, and material thermal expansion coefficient is low, and anti-wear performance is good, and shock resistance is strong.Long service life, reduces maintenance and repair expense.Metal felt point of the present invention is welded on clip, after clip inner liner metal felt, with pipeline, the laminating degree of circuit is better, not only be suitable for the fastening fixing of conventional pipeline, circuit, and meet pipeline, circuit fastening fixing of engine in Aeronautics and Astronautics industry, and can ensure that clip can bear powerful vibration and the high temperature of aircraft, improve security and the fastening fixing reliability of clip.
