Description

Heald frame crossbeam with carbon fiber reinforcement

Technical Field

The utility model relates to a heald frame crossbeam, concretely relates to heald frame crossbeam of coated carbon fiber reinforced material on traditional aluminum alloy crossbeam basis.

Background

The heald frame is the main part of the loom for carrying out the shedding motion of the warp yarns and is the weakest part of the shedding mechanism. The performance aspect requires that it move smoothly, have good rigidity, be firm and durable, and be light in weight. On a high-speed loom, a heald frame bears a large inertia load, and the large inertia load not only easily causes the breakage of the heald frame and restricts the weaving speed, but also increases the energy consumption.

The cross beams are the main components of the heald frame, the weight of the cross beams accounts for about 65 percent of the weight of the whole heald frame, and the weight reduction of the cross beams greatly reduces the total weight of the heald frame. The weight is reduced, meanwhile, the structural strength of the heald frame is weakened, researches show that breakage and failure of the heald frame mostly occur in the cross beam, and the possibility that the heald frame is broken can be reduced by improving the strength of the cross beam.

Along with the continuous deepening of the understanding of the heald frame, the high strength and the light weight of the heald frame are more and more emphasized by people, and the heald frame becomes two important indexes for measuring the quality of the heald frame in the market. As a novel high-strength and high-modulus fiber material, the carbon fiber has the tensile strength about three times that of common carbon steel, the weight is only two thirds that of aluminum alloy, and the application of the carbon fiber is increasingly popularized, so that the application of the carbon fiber in an aluminum alloy heald frame becomes possible.

The aluminum alloy crossbeam coated by the carbon fiber cloth is a form of applying the carbon fiber material to the heald frame, but because the carbon fiber cloth has a complex construction process, carbon fiber wires are not easy to bend at right angles and small structures, and are easy to break due to overlarge force application, and the like, the form is difficult to apply to batch production.

Disclosure of Invention

For solving above-mentioned technical problem and satisfying the market demand, the utility model aims to provide a high strength, lightweight, and the heald frame crossbeam that the construction process degree of difficulty is little, easily mass production.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a heald frame crossbeam with carbon fiber reinforcement, includes aluminum alloy crossbeam section bar and carbon fiber reinforcement structure, carbon fiber reinforcement structure half cladding is on aluminum alloy crossbeam section bar.

The carbon fiber reinforced structure is a carbon fiber reinforced structure of a carbon fiber pultrusion profile.

The carbon fiber reinforced structure is a carbon fiber cloth carbon fiber reinforced structure.

The carbon fiber reinforced structure is U-shaped, and the aluminum alloy beam profile comprises a top semicircular structure. When the carbon fiber reinforced structure is carbon fiber cloth, the U-shaped carbon fiber reinforced structure and the top semicircular structure are matched, so that the problems that carbon fiber yarns are not easy to bend at right angles and small structures and are easy to break due to overlarge force application in the prior art can be solved.

The aluminum alloy beam profile and the carbon fiber reinforced structure are connected in a gluing mode. For example, glue and non-setting adhesive are adopted for gluing, the gluing process is simple and convenient, complex process equipment is not needed, and gluing operation does not need to be carried out at high temperature and high pressure, so that a gluing piece is not easy to deform, and the stress distribution of joints is uniform. In general, a glue joint has good sealability, electrical insulation and corrosion resistance.

And sawteeth are arranged on one surface of the aluminum alloy beam profile, which is in contact with the carbon fiber reinforced structure. The design of sawtooth through increasing roughness, can improve the adhesive force of aluminum alloy crossbeam section bar and carbon fiber reinforced structure.

The utility model discloses with the half cladding of carbon fiber reinforced structure on aluminum alloy crossbeam section bar to play the effect of consolidating aluminum alloy crossbeam section bar, and can also guarantee that the heald frame crossbeam is as light and handy as far as. And the utility model discloses a scheme of half cladding, technology is simpler, also can reduce carbon fiber reinforcement structure cladding as far as in the right angle department and the tiny structure department of aluminum alloy crossbeam section bar, avoids the carbon fiber silk to be difficult to the shortcoming of crooked, too big easy rupture again of application of force in right angle department and tiny structure department.
