Embodiment 1

[0036] Such as figure 2 , Figure 5 to Figure 7 As shown, the manufacturing method of the aluminum honeycomb core includes: Step S1, rolling or stamping the aluminum foil strip substrate 201, so that the aluminum foil strip substrate 201 forms a corrugated sheet substrate 100; and Step S2, for multiple The sheet-shaped substrates 100 are stacked sequentially and two adjacent sheet-shaped substrates 100 are welded to form the aluminum honeycomb core 1 .

[0037] The manufacturing method of this aluminum honeycomb core effectively avoids the stretching process in the traditional manufacturing method, that is, does not rely on the stretching process to form a hexagonal core grid, so the aluminum honeycomb core 1 provided by the present invention is used to manufacture The aluminum honeycomb core 1 is not limited by the condition of being stretched and formed into a hexagon, which solves the problem that the sheet-like base material 100 is too thick or too wide to be easily stre...

Embodiment 2

[0056] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 is that step S30 is also included after step S2, using a brazing process to directly weld reinforcement plates on both sides of the aluminum honeycomb core 1, or using a brazing process to weld reinforcement plates on both sides of the aluminum honeycomb core 1 Welding between core layers. If the reinforcement plates are welded on both sides of the aluminum honeycomb core 1 or the two adjacent honeycomb cores 1 are welded by brazing, there is no need to use the dipping process on the aluminum honeycomb core 1, and the structural strength of the aluminum honeycomb core 1 can also be improved. . Welding two adjacent aluminum honeycomb cores 1 by brazing process includes brazing between corrugated sheet substrates 100. Compared with the cemented aluminum honeycomb core 1 after brazing, the aluminum honeycomb core 1 can make the core layer A firm metallurgical bond is formed between them, t...

Abstract

The invention provides a manufacturing method for aluminum honeycomb cores. The manufacturing method comprises the following steps: (S1) aluminum foil strip substrates are rolled or punched to form corrugated flaky substrates; and (S2) multiple flaky substrates are laminated in sequence; and two adjacent flaky substrates are welded to form the aluminum honeycomb cores. The manufacturing method ofthe aluminum honeycomb cores solves the problems of complicated procedures in a manufacturing method of the aluminum honeycomb cores in the prior art, irregular core cells, low strength and low production efficiency of prepared aluminum honeycomb cores caused by difficult control of the manufacturing method of the aluminum honeycomb cores for thicker aluminum foils, and limitation of the product application fields.

Description

technical field [0001] The invention relates to the technical field of honeycomb cores, in particular to a method for manufacturing aluminum honeycomb cores. Background technique [0002] Aluminum honeycomb core is widely used as a shock-absorbing and cushioning material in aerospace and ship fields because of its light and thin texture, high strength, low relative density, high compression deformation capacity, and excellent deformation controllability. [0003] The existing manufacturing method of the aluminum honeycomb core is mainly formed by gluing or welding the flat aluminum foil strip base material first, and then stretching the connected aluminum foil strip base material; the aluminum honeycomb formed by the stretching process will be affected. Due to the influence of various factors such as sizing width, glue bonding strength, and basic mechanical and physical properties of the core material, local insufficient or excessive stretching occurs during the stretching p...
