Method and equipment for winding carbon fiber yarns on annular mandrel

Abstract

The invention discloses a method and special equipment for winding carbon fiber yarns on an annular mandrel, which comprise coiled yarn manufacture, positioning of the annular mandrel, self-rotation of the mandrel, a winding method and the special equipment for the method. After the invention is adopted, yarns can be continuously wound, the manufacturing process of products is simple and convenient, the manpower and the time of manual yarn winding are reduced, and the production efficiency is improved; the rotary speed of a machine platform is uniform and stable, and the strength and the spacing of yarn winding are uniform, so that the rigidity and the strength of molded products are ensured, the rejection rate is reduced, the carbon fiber layers of the products are smooth, and have uniform wall thicknesses and are not deformed, and the sizes of the products can be effectively controlled; the products are continuously wound to be molded, and the inside and outside of the whole pipe wall have uniform materials, and an overlapping phenomenon does not occur, so that the carbon fiber layers of the products are smooth, and have uniform wall thicknesses and are not deformed; the whole carbon fiber tapes are whole tapes, and so the carbon fiber layers do not need to be cut always, so that raw materials are simplified and saved; the rotating speed of the mandrel is changed, and the angle between the yarns and the mandrel, and the staggered angle between the two adjacent yarn layers are variable, so that the performances of various products are met.

Description

technical field [0001] The invention relates to a method for winding carbon fiber yarn to an annular mandrel and a device for winding carbon fiber yarn used in the method. Background technique [0002] Due to the high cost of carbon fiber materials, the carbon fiber products made of them are basically shells. During production, multi-layer carbon fiber cloth is wrapped on the body that is consistent with the shape of the product and slightly smaller than the product size to make a semi-finished product, and then put it Inflate, pressurize, and heat the mold to solidify the carbon fiber layer, and then take out the green body to obtain a carbon fiber product; in order to increase the strength of the carbon fiber product, the textures of adjacent carbon fiber cloths must be interlaced at a certain angle when making carbon fiber products. Layer by layer to achieve the desired thickness of the product, currently these tasks need to be done manually, which is not only cumbersome,...

Problems solved by technology

[0004] From the above description, it can be seen that it takes 2-3 hours to cover a single inner tube mandrel, which is not only time-consuming and labor-intensive, but also cannot ensure the flatness, compactness and uniform thickness of the carbon fiber layer, which directly affect the strength and performance of the product. quality and quality; in order to meet the width, length and texture requirements of the product, the fiber cloth is constantly cut, resulting in a large waste of material, and because the carbon fiber cloth cannot be recycled, in order to reduce the cost and reduce the impact on the environment, it is necessary to improve the quality of the material Utilization
