Method for manufacturing aluminum honeycomb core

Abstract

The invention provides a method for manufacturing an aluminum honeycomb core and relates to the technical field of honeycomb cores. The method comprises the following steps: (1) cleaning a strip-shaped aluminum foil by using ultrasonic waves; (2) coating one side of the strip-shaped aluminum foil with glue; (3) cutting the strip-shaped aluminum foil into aluminum foil sections; (4) overlapping the aluminum foil sections; (5) performing hot-pressing on the overlapped aluminum foil sections in a hot press for forming overlap blocks; (6) cutting the overlap blocks into cutting strips; and (7) stretching the cutting strips by using a hydraulic drawing mill, so that the cutting strips are unfolded to form the aluminum honeycomb core. According to the method disclosed by the invention, adhesion among the aluminum foil sections can be tight, the position of a gluing area is aligned in the overlapping process, and the cutting strips are stably unfolded.

Description

technical field [0001] The invention relates to the technical field of honeycomb cores, in particular to an aluminum honeycomb core manufacturing method. Background technique [0002] The honeycomb core refers to the core sandwiched between two skins in the honeycomb panel, which has a honeycomb-shaped cell as a whole. Honeycomb panels are widely used in many fields such as construction and aviation, and the honeycomb core has a very important effect on the performance of honeycomb panels. [0003] In order to make the cutting strips form a honeycomb structure after unfolding, during the lamination process of the aluminum foil, each glued area on each piece of aluminum foil must be located between two adjacent glued areas of the aluminum foil in contact with it. In the middle position, it often takes a long time to align the position. [0004] Moreover, in the past, when the cutting strip was unfolded, two pieces of aluminum foil on the surface and the lower surface of the...

Problems solved by technology

[0003] In order to make the cutting strips form a honeycomb structure after unfolding, during the lamination process of the aluminum foil, each glued area on each piece of aluminum foil must be located between two adjacent glued areas of the aluminum foil in contact with it. In the middle position, it often takes a long time to align the position

[0004] Moreover, in the past, when the cutting strip was unfolded, two pieces of aluminum foil on the surface and the lower surface of the cutting strip were usually clamped with a clamp, and then the cutting strip was unfolded. Because the clamp could not tightly clamp the aluminum foil, it was easy to loosen, so It is impossible to pull apart thicker honeycomb cut strips, and it is easy to cause deformation of the stretched honeycomb core

[0005] In addition, the bonded aluminum foil of the honeycomb core also has the problem of insufficient adhesive force, and it is easy to separate under the action of external force
