Abstract
A method for preparing a novel cellular plate includes such steps as providing a whole thin plate as a core plate, machining a series of concave-convex supporting bodies staggered on it, linking the vertical ribs to the concave-convex end faces, and fixing both surface sheets.
Description
Technical field
The present invention relates to a kind of processing method of combined type material, the preparation method of the cellular board of especially dual-use new construction.
Background technology
Cellular board is used widely in fields such as Aero-Space, aircraft, train, boats and ships, building owing in light weight, series of advantages such as specific strength is high, rigidity is big, stability is wicked, heat-and sound-insulating.There are five big problems in existing cellular board: (1) honeycomb core is by boning or being welded by hundreds of length of a film strip materials (can be metal, paper, plastics or other material).The inevitable defective of introducing in bonding or welding process, influence intensity and stability subsequently.(2) have that geometry is irregular, the honeycomb size is inhomogeneous, shortcoming such as self mechanical property is low, bearing capacity is inhomogeneous.(3) honeycomb core combines with the T shape wire that is combined into of panel, and intensity, rigidity, the stability of cellular board are restricted.(4) the manufacturing cost height of honeycomb core, can't be embodied as the coil type serialization and produce.(5) owing to honeycomb core, the production of cellular board also is difficult to realize serialization production, to making the cellular board production cost high, has limited cellular board and has been used in bigger wider scope.
In addition, for the adhesive type cellular board, because the connected mode of honeycomb core self and honeycomb core and panel is physical bond, the working environment of its intensity, service life and permission is restricted by the adhesive performance to a great extent.Under high humidity, vibration working environment frequent, too high or too low for temperature, coming unstuck easily in honeycomb core and panel junction, causes in use, and institute's bearing load does not reach the yield limit of the material that uses far away and lost efficacy, and mechanical property is lower.For the braze welding type cellular board, though the connected mode of honeycomb core self and honeycomb core and panel all is a metallurgical binding, the aspects such as working environment of its intensity, service life and permission improve a lot than gluing cellular board, but still being the welding of T shape wire between honeycomb core and the panel, still is the weak part of cellular board.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new method for preparing honeycomb plate, can make the intensity of cellular board higher, rigidity is bigger, it is more convenient to manufacture, manufacturing cost is lower.
Solving the scheme that technical problem of the present invention adopts is: (1) honeycomb core is prepared by whole volume/piece thin plate, processes the staggered supporter of a series of convex-concaves in the above, and the convex-concave end face and the vertical rib of supporter are integral; (2) the supporter plane with upper and lower panel and honeycomb core is fixed into one.
In order to obtain better mechanics load-carrying properties, honeycomb core is added man-hour, with the vertical rib of the supporter of honeycomb core be processed into closed-loop around geometry, as section is shapes such as triangle, four limits, hexagonal, circle, closed-loop around vertical rib the stability of honeycomb core is improved, form three-dimensional beveled structure with the convex-concave transverse plane, both improved the rigidity of honeycomb core, obtained strong bonded again with panel.
In addition, also can adopt of the same race/foreign material combination to honeycomb core and upper and lower panel, the production cost of this cellular board is reduced, and the mechanics load-carrying properties improve as far as possible as far as possible according to the concrete purposes of cellular board.
The invention has the beneficial effects as follows: honeycomb core is processed to monoblock type concave-convex structure, can make that the honeycomb core geometry is more regular, size is more even, the vertical rib limit of existing carrying, the convex-concave transverse plane of being convenient in conjunction with (bonding or welding) is arranged again, its intensity, rigidity, stability are all improved a lot.Become firm face combination with combining of panel, further make intensity, rigidity and the stability of cellular board obtain once more to promote by the combination of the unstable T shape of tradition wire.The more important thing is that the preparation technology that makes honeycomb core and the production technology of cellular board become simply, manufacturing cost greatly reduces, and the interruption that becomes legacy cellular plate seal formula is produced to free of discontinuities and produced continuously.In addition, no matter be adhesive type cellular board or welded type cellular board, all can realize economical and efficient production.
