Description
Technical field
The invention belongs to cellular board technical fields, and in particular to the preparation process without glue aluminum honeycomb plate.
Background technique
Cellular board is since light-weight, specific strength is high, rigidity is big, stability is good, heat-and sound-insulating and pollution-free etc. a series of
Advantage is used widely in the fields such as aerospace, aircraft, train, ship, building.It is common both at home and abroad at present
Cellular board either core material itself is still compound between panel and core material, is adhesive means, and connection type is physical bond,
Its intensity, service life and the working environment of permission are largely restricted by Adhensive performance.The molding honeycomb of gluing
Plate mechanical property is lower, structure built on the sand, moreover, pollution can be generated in the connection type reproduction of gluing, not environmentally.To understand
Certainly problem, currently, mostly using method for welding formed honeycomb plate.
Soldering is to make solder using metal material more low-melting than base material, and weldment and solder heat are melted to higher than solder
Point is lower than base material fusion temperature, soaks base material using liquid solder, fills play movement and realizes connection with base material phase counterdiffusion
The method of weldment.Cellular board is aluminium sheet, and area when soldering is bigger, and aluminium sheet is very easy to deformation in the case where heated.
The prior art is usually that aluminium sheet is sent directly into soldering oven with the cellular board for being coated with brazing flux to carry out high temperature brazing, although this method
Simple process, but it is usually easy to happen aluminium sheet deformation, to influence the surface smoothness of composite plate, influence product quality.
Summary of the invention
The technical problem to be solved by the present invention is in view of the foregoing drawbacks, provide the preparation process of no glue aluminum honeycomb plate,
The cellular board deformation of lead welding and shaping is small, and cellular board quality is high.
It is as follows that the technical scheme adopted by the invention to solve the technical problem:
