Title:
ALUMINUM HONEYCOMB CORE PRODUCTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/075946
Kind Code:
A1
Abstract:
The present invention relates to the manufacturing field of honeycomb cores, and provides an aluminum honeycomb core production method, comprising: an adhesive applying step: applying an adhesive to aluminum foil layers so that the aluminum foil layers are bonded to form a dual-layer/multi-layer aluminum foil; an adhesive pre-applying step: applying the adhesive to the surface of the dual-layer/multi-layer aluminum foil; a cutting step: cutting the dual-layer/multi-layer aluminum foil to form aluminum foil strips; a bonding step: bonding the plurality of aluminum foil strips to form an aluminum honeycomb core; and a stretching step: stretching the aluminum honeycomb core to be deformed to form the aluminum honeycomb core. By applying the aluminum foil to the honeycomb core, the structural strength and connection/detaching strength of the honeycomb core are improved. An aluminum honeycomb core production device improves the production efficiency and product quality of the aluminum honeycomb core.
