Cellular board core formed through folding and forming method thereof

Abstract

The invention relates to a cellular board core formed through folding and a forming method thereof. The cellular board core formed through folding comprises an upper end board, a lower end board and a cellular core, wherein the cellular core is of a polygonal, cellular and net structure and formed by folding and bonding the whole sheet material, and plane blocks allowing the end boards to be bonded to are arranged on the end faces of the core of the polygonal, cellular and net structure formed by folding the whole sheet material. The cellular core is formed by folding the whole sheet in order, so that the problems of an uncertain shape of the core caused by insufficient stretch and / or excessive stretch during stretch forming of the cellular core and loss of compressive property of a cellular board due to the uncertain shape of the core are solved. The cellular board core formed through folding has the advantages of being stable and reliable in forming, higher in integral strength and unlikely to generate a divergence phenomenon.

Description

technical field [0001] The invention relates to a sandwich structure of a sandwich panel and a manufacturing method thereof, in particular to a folded and formed honeycomb panel sandwich structure and a forming method thereof, which can effectively reduce the resistance of the honeycomb panel to Compressive performance loss, and when the honeycomb sandwich core is combined with the upper and lower panels, the contact area between the sandwich core and the panel can be increased, and the bonding force between the sandwich core and the panel can be improved. It belongs to the technical field of sandwich panel manufacturing. Background technique: [0002] Honeycomb products are a new generation of environmentally friendly packaging products. They are unanimously welcomed by the market for their light weight, low price, high strength, and recyclability. Especially in some developed countries and regions, they have been widely used in various packaging industries. . [0003] T...

AI Technical Summary

Problems solved by technology

[0010] Although the above-mentioned patents all relate to the honeycomb core and its manufacturing method, they have not changed the generally adopted method of first making the frame of the honeycomb core into strips, and then The conventional practice of bonding these strips and stretching them to form a honeycomb sandwich, so there will still be "understretching" and / or "overstretching" phenomena, resulting in an uncertain shape of the core Sexual problems, so still need to be further improved
