Problems solved by technology

In the brazing of the honeycomb core and the metal plate, the contact area between the two is less than 10% (generally 3-8%), that is to say, even if 100% of the contact area can be welded (the brazing difficulty of the honeycomb plate is much greater than Conventional plate), the welding area between the metal plate and the honeycomb core is also less than 10%, so the connection strength between the honeycomb core and the metal plate is difficult to reach a very high level, only 10% or less of the brazing strength of the usual plate

Embodiment 1

[0066] see Figure 1 to Figure 11 , an embedded latitudinal reinforced metal honeycomb structure, comprising a honeycomb core A, the honeycomb core A has a plurality of trapezoidal bars 1 arranged parallel to each other, each trapezoidal bar 1 extends along the warp direction, and the trapezoidal bars 1 have A plurality of unit sections B connected end to end in sequence, the unit section B is composed of a first bottom plate 101, a first waist plate 102, a second bottom plate 103 and a second waist plate 104 which are integrally connected in sequence, the first waist plate 102 and the second waist plate The waist plate 104 is symmetrically distributed at both ends of the second bottom plate 103; the first bottom plate 101 and the second bottom plate 103 of adjacent trapezoidal strips 1 are fixedly connected to form a honeycomb core A with multiple cells; it also includes at least two embedded Board 2, the inner panel 2 extends along the weft direction and is perpendicular to ...

Embodiment 2

[0085] Repeat embodiment 1, the difference is only: the non-working surface of the present embodiment is provided with a plurality of holes 10 on the inner panel, and the plurality of holes are distributed sequentially along the length direction of the inner panel; the diameter of the hole is 15mm round hole.

[0086] On the one hand, the setting of the hole can play a role in reducing weight, on the other hand, it can be used as a process hole to facilitate the electrode head of the resistance welding machine to enter the cell, and spot weld the connection platform between the inner panel and the trapezoidal strip on the non-working surface .

Abstract

The invention relates to a built-in type weft-direction reinforced metal honeycomb structure and a manufacturing method thereof. The built-in type weft-direction reinforced metal honeycomb structure comprises a honeycomb core. The honeycomb core is provided with multiple parallel trapezoidal strips. Each trapezoidal strip is provided with at least two unit sections which are sequentially connectedin an end-to-end manner. Each unit section is composed of a first base plate, a first waist plate, a second base plate and a second waist plate which are sequentially connected in an integrated manner, wherein the first waist plate and the second waist plate are symmetrically distributed at the two ends of the second base plate. The first base plate and the second base plate of every two adjacenttrapezoid strips are fixedly connected, and the honeycomb core with multiple unit cells is formed. The built-in type weft-direction reinforced metal honeycomb structure further comprises built-in plates. The built-in plates extend in the weft direction and is perpendicular to the width direction of the trapezoidal strips and embedded into the unit cells which are sequentially distributed in the weft direction. The base plates corresponding to the unit cells which are sequentially distributed in the weft direction are fixedly connected with the built-in plates. The honeycomb structure is highin strength in all directions.

Description

technical field [0001] The invention relates to an embedded latitudinal reinforced metal honeycomb structure and a manufacturing method thereof, belonging to the field of composite plates / profiles. Background technique [0002] The honeycomb structure is the result of natural evolution, and its practical significance is to use the least material to obtain the strongest structure. This feature meets the demand for lightweight materials in the engineering field. Today, the artificial honeycomb structure with honeycomb panels as the main development direction has made great progress. In addition to light weight and high strength, this structure also has many excellent properties such as energy absorption, shock absorption, sound insulation, and heat insulation. [0003] Chinese patent specification CN102774042A discloses a honeycomb reinforced plate and its manufacturing method. The manufacturing method of the honeycomb core material is as follows: first cut the metal plate in...
