Manufacturing method of aluminum honeycomb core

Abstract

The invention relates to the technical field of manufacturing techniques of aluminum products, and provides a manufacturing method of an aluminum honeycomb core. The method includes the steps that S1,aluminum foil narrow material is cut, and a plurality of aluminum foil strips with the same length are obtained; S2, the aluminum foil strips are successively stacked, the edges of the aluminum foilstrips are aligned, each of aluminum foil strips is pressed tightly and fixedly welded to the aluminum foil on the upper layer after each of aluminum foil strips is stacked, and a core strip is obtained; and S3, the core strip is stretched, and a honeycomb core is obtained. The manufacturing method of the aluminum honeycomb core is only need the working procedure of cutting, pressing tightly, welding, stretching and the like. The technique process is simplified, equipment and labour input are reduced, the electric energy loss of heat pressing process can also be completely eliminated, and theproduction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of production technology of aluminum products, in particular to a method for manufacturing an aluminum honeycomb core. Background technique [0002] In today's society, more and more places need to use weight-reducing and lightweight materials to achieve energy-saving and efficiency-enhancing purposes. Aluminum honeycomb panels have emerged as the times require. The core layer of the honeycomb structure and the plate formed by the combination of the three are currently widely used, including aerospace, ship transportation, military, rail transit, etc., whether it is the traditional glued aluminum honeycomb panel or the new brazed aluminum honeycomb panel Panel, the inner core layer is an essential part, so the honeycomb core is the key of the aluminum honeycomb panel and is the main body. [0003] At present, the manufacturing method of aluminum honeycomb core is mainly based on stretching after gluing. fi...

AI Technical Summary

Problems solved by technology

[0005] The existing production method of this kind of honeycomb core needs to go through many complex and locked processes such as gluing, hot pressing, sawing and slitting, stretching, head and tail cutting, etc., the production efficiency is low, and there are many types of equipment required for production , the equipment investment cost is high; many processes lead to a large number of stations, and each station needs to be equipped with corresponding manpower, and the labor cost is high; in addition, the heat-pressing process consumes a lot of energy, which further increases the cost

[0006] When sawing and slitting, due to the limitations of mechanical processing, the head and tail materials will be close to 1 / 6 of the core block and cannot be processed. At the same time, the sawing knife width will also constitute a waste of materials, so the waste of materials is serious, and the effective utilization rate of materials reduce

At present, the precision level of sawing processing needs to be improved. The thickness and size of the honeycomb core after sawing and slitting are poor, which affects product quality.

[0007] Glue and solvents are chemicals, flammable and not environmentally friendly, and the concentration of the glue applied by the glue is affected by temperature and humidity, and the concentration is unstable, which will cause degumming in low-concentration areas or high-concentration areas that cannot be pulled apart when the core strip is stretched. situation, causing the product to be scrapped

[0008] If the brazed honeycomb panel is produced, the honeycomb core must be brazed and degummed at high temperature in the furnace, which will generate waste gas and is not environmentally friendly. At the same time, the honeycomb core is brazed once, which will consume additional power of the brazing furnace and greatly increase the cost.
