Further, said relatively second mould of said first mould is done rolling movement.

Further, the cup depth of said first recess is greater than the cup depth of said second recess.

Further, the height of said first convexity is greater than the height of said second convexity.

Further, said first, second convexity has the surface of the crest shape that is slick and sly, and first, second recess has the surface of the trough shape that is slick and sly.

Further, the surface of said crest shape and/or trough shape is sinusoidal wave or parabola or involute or hyperbola formula curved surface.

Further, be provided with at least 2 second convexities between per two first convexities in said first mould.

Further, be provided with at least 1 second recess between per two first recesses in said second mould.

Further, second number of protrusions between per two first convexities of said first mould is greater than the number of second recess between per two first recesses of said second mould.

Further, said first mould is to have said first, second protruding serrated roller, and said second mould is the profile of tooth bar that has said first, second recess.

Can form through the said device among the present invention and to have large curved surface and bi-curved honeycomb article, but need not cut and splice manufacturing, thereby reduce technology difficulty, and guarantee the quality of honeycomb products.

Description of drawings

Fig. 1 is the structure and the working state schematic representation of the shaped device of the flexible honeycomb sandwich among the present invention.

The specific embodiment

Be elaborated in the face of technical scheme of the present invention down.

Fig. 1 shows the structure and the working state schematic representation of the shaped device of the flexible honeycomb sandwich among the present invention.

As shown in Figure 1, said shaped device comprises first mould 1 and second mould 2.Said first mould 1 is provided with a plurality of first convexities 3 and a plurality of second convexities 4, the said first protruding 3 and second protruding 4 compartment of terrain setting successively, and preferably, said first protruding 3 height is greater than the height of said second convexity 4.Said second mould 2 is provided with from individual first recess 5 and a plurality of second recesses 6, and said first recess 5 and second recess 6 compartment of terrain successively are provided with, and preferably, the cup depth of said first recess 5 is greater than the cup depth of said second recess 6.

At each constantly; First and/or second recess of at least one said second mould that first and/or second convexity of at least one said first mould is corresponding with it respectively contacts engagement typely, so that will place the flexible thin material's moulding agley between the said corresponding part that contacts between said first mould 1 and second mould 2 engagement typely.Said when contacting when breaking away between said first mould and second mould, said flexible thin material relies on the plasticity of himself to keep shape agley engagement typely.

Preferably, said first, second convexity has the surface of the crest shape that is slick and sly, and first, second recess has the surface of the trough shape that is slick and sly.Further, preferably, said first, second raised surface matches with the surface of said first, second recess.Preferably, the surface of said crest shape and/or trough shape can be sine wave, parabola, involute, hyperbola formula curved surface, also can be the curved surface with other predetermined form.Preferably, the surface of the surface of said crest shape and trough shape can select multi-form curved surface combined from above-mentioned various forms of curved surfaces.

Preferably, be provided with at least 2 second convexities between per two first convexities in said first mould, preferably, be provided with 2 second convexities.Preferably, at least two second protruding height between per two said first convexities can be identical, also can be different.

Preferably, be provided with at least 1 second recess between per two first recesses in said second mould, preferably, be provided with 1 second recess.Preferably, at least 1 second concave depth between per two said first recesses can be identical, also can be different.

Preferably; When said first mould and second mould are in engagement type ground state of contact following time; First protruding first recess with said second mould of said first mould meshes accordingly; Further, second of said first mould protruding second recess with said second mould meshes accordingly; Especially, second protruding second recess with every at least one second mould of every at least two first moulds contacts accordingly engagement typely, and for example, second convexity of 2 first moulds contacts with second recess of 1 second mould accordingly engagement typely.Preferably, second number of protrusions between per two first convexities of said first mould is greater than the number of second recess between per two first recesses of said second mould.
