Method for fixing carbon fiber product

Abstract

The invention relates to a method for fixing a carbon fiber product, which is used for fixing the carbon fiber product to be cut and processed by adopting a fixing jig and adopting at least one of suction cup adsorption and positioning piece positioning. The distance between the suction positions of the suction cups on the product and the to-be-cut edge of the product and the distance between the suction cups are determined, the shapes of the suction cups and the sizes of cup openings of the suction cups are selected, the suction cups are arranged on a fixing jig, and the product is sucked to the arranged suction cups; the positioning of the positioning pieces comprises the steps that according to the shape of the product, a plurality of positioning pieces are arranged on the product, positioning grooves matched with the positioning pieces in shape and position are formed in the fixing jig, and the positioning pieces of the product are inserted into the corresponding positioning grooves, so that the problems of adsorption and positioning during processing of the carbon fiber product are solved, and the processing quality of the carbon fiber product is greatly improved; and the production yield is improved, so that the manufacturing cost of the carbon fibers is reduced.

Description

technical field [0001] The invention belongs to the field of carbon fiber composite materials, in particular to a method for fixing carbon fiber products. Background technique [0002] Lightweight materials are one of the important measures to achieve energy saving and emission reduction, and are of great significance to the sustainable development of the national industry. Carbon fiber composite materials are widely used in aerospace, rail transit, automobile, medical and other fields due to their light specific gravity, high specific strength, and good fatigue resistance.

Carbon fiber composite materials are widely used in aerospace, rail transit, automobile, medical and other fields due to their light specific gravity, high specific strength, and good fatigue resistance. However, carbon fiber composite materials and carbon fiber composite components have high precision and high quality. Requirements, making processing a key task. In the quality control of processing and cutting, the adsorption capacity becomes one of the important parameters. If the carbon fiber composite material or carbon fiber composite component cannot be stably adsorbed before processing, it will cause it during processing and cutting. Shaking and making the product scrapped

[0003] At present, carbon fiber products, especially products with special shapes such as automobiles, have complex curved surfaces, which makes the product installation inconvenient, the product cannot be positioned, and it is difficult to fix, which will affect the processing

Because the surface of the carbon brazing fiber contains a molding release agent, the surface is bright and smooth, so that the product cannot absorb the tooling, and the installation must be manually assisted by elbow clamps, which has risks such as production safety, low processing efficiency, and easy collisions.

The positioning accuracy of the product is poor, which leads to the deviation of the predetermined adsorption position, which leads to the deterioration of the adsorption fastness, and the product is easily scrapped during processing.
