Abstract
The utility model relates to a porous aluminium honeycomb structure. Through holes with the same diameter are uniformly beaten out on the walls of all units of a honeycomb by a laser. The through holes on the walls of all units make air fluently flow into and out of the honeycomb body and keep the air permeability of the whole honeycomb core. The pressure in and out of the honeycomb is in the same level. The composite plates of the aluminium honeycomb can not be broken in high vacuum environment conditions due to the inner and outer pressure difference resulting from air in the honeycomb core. The utility model meets the work requirements of the aluminium honeycomb structure in high vacuum states.
Description
Technical field: the utility model relates to a kind of porous breathable aluminium honeycomb structured body.
Background technique: known aluminium honeycomb structured body, in the honeycomb core of honeycomb sandwich panel commonly used, the volume of solid material only accounts for 1%-3%, is the air that is in closed state in its complementary space.Under high vacuum environment, if residual in the honeycomb core have air then may be because the external and internal pressure difference causes honeycomb core to break and produces beyond thought serious consequence.Past, adopt on the honeycomb core cell-wall with mechanical drill boring to vacuumize when using, still, this method not only wastes time and energy and damages the honeycomb aluminium foil because of mechanical pressure.More can not guarantee the gas permeability of monoblock honeycomb core.
Adopt laser to be untouchable processing in the punching of aluminium honeycomb aluminium foil, the heat-affected zone is little, processes meticulously, can finish the technology that conventional method can't realize.
" cutter " that laser boring is used is the luminous point after focusing on, and laser beam machining speed is rapid, and is with low cost.Laser boring does not need human intervention by computer controlled automatic during production, can significantly reduce process time, cuts down finished cost, and improves quality of processing.
Use laser beam perforating machine to get uniform through hole on the cell-wall of each cellular unit of aluminium honeycomb core, it is manufactured aluminum honeycomb panel, the through hole on each cellular unit wall does not have obvious influence to the mechanical property of monoblock aluminum honeycomb panel, can guarantee its usability.。
Summary of the invention: the purpose of this utility model is for a kind of a kind of porous breathable aluminium honeycomb structured body that is adapted at use under the high vacuum condition is provided.
The purpose of this utility model is to realize like this, a kind of porous breathable aluminium honeycomb structured body, on the cell-wall of each honeycomb, use laser to get the identical uniform through hole of diameter, make the monoblock cellular board keep air permeability and good, satisfy the job requirement of aluminium honeycomb structured body under high vacuum state.It is characterized in that:
Use laser on the cell-wall of aluminium honeycomb core, evenly to get air hole, form porous breathable aluminium cellular structure.For being hot pressed into the aluminium honeycomb core piece, become the porous breathable aluminium honeycomb composite plate through the cutting drawing and setting.
Described cell-wall aluminium honeycomb core is an aluminium foil.
Described air hole is to use laser beam perforating machine evenly to get air hole on aluminium foil.
The utility model has the advantages that: use laser beam perforating machine on each cellular unit wall of aluminium honeycomb core, to get the identical uniform through hole of diameter, through hole on these cell-wall makes air free flow and keep the gas permeability of integral honeycomb core inside and outside honeycomb ceramics, the same pressure state in inside and outside place of honeycomb core, guaranteed that aluminium honeycomb composite plate is under the high vacuum environment condition, can not cause aluminum honeycomb panel to break, satisfy the job requirement of aluminium honeycomb structured body under high vacuum state because of existing air to produce the external and internal pressure difference in the aluminium honeycomb core.
Description of drawings: the utility model is described in further detail below in conjunction with the accompanying drawing example:
Fig. 1 is a legacy cellular structural upright schematic representation;
Fig. 2 is the utility model porous breathable aluminium cellular structure schematic perspective view;
Fig. 3 is the utility model porous breathable aluminium cellular structure plan view;
Fig. 4 is the utility model porous breathable aluminium cellular structure plan view;
Fig. 5 is that the utility model porous breathable aluminium cellular structure A is to side view.
Embodiment: shown in Fig. 2 to 5, it has provided a kind of novel porous ventilative aluminium cellular structure, use the high power density energy that produces after laser focuses on and be implemented in laser boring on the honeycomb aluminium foil. under the control of computer, make the laser discharge by pulse, thereby output-controlled repeat high-frequency pulse laser, form certain frequency, the light beam of certain pulsewidth, this pulsed laser beam conducts and reflects through light path and focus on the honeycomb aluminium foil surface by focusing lens and forms trickle one by one, the high-energy-density hot spot is with moment high temperature melt or gasification honeycomb aluminium foil. and each high-octane laser pulse moment sputters a tiny hole with the honeycomb aluminium foil.
Claims (2)
1. porous breathable aluminium honeycomb structured body, it has many folded-sheet honeycomb structures unit, each cellular unit has 6 to have equal cell-wall, the identical through hole of some diameters that wherein all has laser to get on each cell-wall, and air can free flow in all cellular units.
2. according to the cellular structure of claim 1, it is characterized in that: all cellular units are connected by the through hole on the cell-wall separately, but air free-flow.
