Description
Technical field
Technical field of producing more particularly to a kind of manufacturing method of aluminium honeycomb core the present invention relates to aluminum products.
Background technology
Today's society, more and more places need to use loss of weight, light-weighted material, to reach the mesh such as energy efficiency
, aluminum honeycomb panel comes into being, and aluminum honeycomb panel is that top and bottom bottom plate is aluminium sheet, and internal is the sandwich layer of aluminium honeycomb structure,
The plate that three is composed, at present using very extensive, including aerospace, Shipping is military, track traffic etc., nothing
By being traditional gluing aluminum honeycomb panel or new soldering aluminum honeycomb panel, inner core layers are essential parts, therefore bee
Nest core is the key that aluminum honeycomb panel, is main body.
Based on gluing post-tensioning shaping, with reference to Fig. 1, aluminum current honeycomb is briefly described in the manufacturing method of aluminium honeycomb core at present
The manufacturing method of core：
Raw material 1 are the aluminium foil with one fixed width, and aluminium foil is cut into several sections according to required length, is existed using automatic double surface gluer
Glue is coated on one section of aluminium foil, forms adhesive tape 2, adhesive tape 2 is alternatively arranged along the length direction of aluminium foil, is so far first layer aluminium foil
3, second layer aluminium foil 3 is laid on first layer aluminium foil 3 and carries out hot pressing, four sides of two layers of aluminium foil to its, first layer aluminium
Adhesive tape 2 on paillon 3 sticks second layer aluminium foil 3, then on second layer aluminium foil 3 in the way of before coating adhesive
Water, the repeatedly above method, if the neat stacking of dried layer aluminium foil is got up, forms pellet 4 afterwards；Thickness according to needed for honeycomb core
Pellet is cut, obtains multiple core items 5；Finally core item is stretched, is shaped to honeycomb core 6.
The production method of existing this honeycomb core is needed by gluing, hot pressing, sawing slitting, end to end stretching, material excision
Etc. the process that many complexity are locked, production efficiency is relatively low, and the device category needed for production is more, and equipment investment cost is big；Work
Sequence causes the quantity of station more more, and each station just needs to be equipped with corresponding manpower, and human cost is higher；In addition, hot pressing process
It consumes energy larger, further improves cost.
During sawing slitting, because mechanical processing limitation, material has close to the 1/6 of pellet and cannot process end to end, saws simultaneously
The wide waste that can also form to material of knife cut, therefore waste of material is serious, material effective rate of utilization reduces.Cutting indexes at present
Precision level have much room for improvement, honeycomb core thickness uniformity is poor after sawing slitting, influences product quality.
Glue and solvent are chemical substance, inflammable and not environmentally, and gluing glue, because being influenced by humiture, concentration is not
Stablize, concentration low local degumming can be generated when core item being caused to stretch or situations such as the high place of concentration can not draw away, cause to produce
Product are scrapped.
If production soldering cellular board, honeycomb core must generate exhaust gas into stove high temperature brazing degumming, not environmentally, while honeycomb core
Once, the electric energy of excess loss soldering oven, cost greatly increases for soldering.
The content of the invention
The technical problem to be solved by the present invention is to：The production method of honeycomb core of the prior art has the following problems：
Tedious process is complicated, it is necessary to by gluing, hot pressing, sawing slitting, end to end stretching, the multiple working procedures such as material excision, production effect
Rate is relatively low, and the device category needed for production is more, and equipment investment cost is big；Process causes the quantity of station more more, Mei Gegong
Position just needs to be equipped with corresponding manpower, and human cost is higher；In addition, hot pressing process energy consumption is larger, cost is further improved.
It needing to use instruments and the materials such as glue, ethyl acetate, saw blade, cooling alcohol in production, auxiliary material is more, of high cost,
And not environmentally.
Sawing slitting process seriously reduces the utilization rate of raw material aluminium foil, and the blade of sawing first has certain thick
Degree, often cuts out a core item, will generate the waste of wide pellet as blade thickness, for example：Knife thickness is 4mm, is needed
The thickness for wanting core item is 12mm, then often cuts a honeycomb pellet for then needing 16mm（12mm+4mm knives are thick）, stock utilization is only
75%, additionally, since the condition limitation of sawing device and gluing stacking cause pellet both sides aluminium foil cannot be perfectly aligned, ruler
Very little, so that the material end to end of honeycomb pellet needs to cut off, to be used outside tolerance, the waste material of this part is about at least
50mm is calculated according to conventional pellet size 600mm wide cuts, and the waste material for just having 1/12 generates, in addition the waste of knife thickness, quite may be used
It sees.
Glue and solvent are chemical substance, inflammable and not environmentally, and gluing glue, because being influenced by humiture, concentration is not
Stablize, concentration low local degumming can be generated when core item being caused to stretch or situations such as the high place of concentration can not draw away, cause to produce
Product are scrapped.
If production soldering cellular board, honeycomb core must have glue volatilization, product can be made to black, pricker into stove high temperature brazing degumming
Weldering yield rate greatly reduces, and generates exhaust gas, and not environmentally, while honeycomb core soldering is once, the electricity of excess loss soldering oven
Can, cost greatly increases.Therefore, it is necessary to which the glue in honeycomb core is removed before production soldering aluminum honeycomb panel.
The technical solution adopted by the present invention to solve the technical problems is：A kind of manufacturing method of aluminium honeycomb core, including with
Lower step：
S1, the narrow material of aluminium foil is cut, obtains the identical aluminum foil strip of several length；
S2, several described aluminum foil strips stack gradually and their edge to it, often be stacked an aluminum foil strip after by its with
The aluminum foil strip of last layer is compressed and is welded and fixed, and obtains core item；
S3, core item is stretched, obtains honeycomb core.
Preferably, in the step S2, the mode of welding is laser welding.
Preferably, when the thickness of the aluminum foil strip is 0.05 ~ 0.2mm, the peak value of power of laser is set as 1 ~ 10kw.
The invention has the advantages that the manufacturing method of this aluminium honeycomb core has the following advantages：
This manufacturing method processes, the technical process such as only needs to cut, compresses, welds, stretching and simplifying, equipment and manually input subtracts
Few, the electric energy loss of hot pressing process also can be completely left out, reduces production cost.
Aluminium foil is fixed by welding, is eliminated the practicality of the auxiliary materials such as glue, ethyl acetate, cooling alcohol, is reduced
Cost.
Since utility knife being not required to cut pellet, waste material will not be therefore generated；Secondly, the length and width of aluminium foil are all being cut out
The margin of tolerance is fully achieved after cutting, is directly welded and fixed after stacking neatly, core item is very carefully and neatly done, need not carry out sawing again to adjust
It is whole to it, so in the utilization rate of raw material, there is larger promotion.
Aluminium foil weld is equivalent to the adhesive tape in traditional handicraft, is welded at once after being folded due to each aluminum foil strip heap,
The problems such as will not misplacing, being not fixed, after core item stretches, the shape of core bore is regular.In addition, the intensity of welding outclass glue
Water, therefore when stretching honeycomb core, the situation of drawing crack can improve product quality and yields well below traditional handicraft.
Glue need not be used in this technique, when production is brazed cellular board, removes from except glue process, exhaust gas will not be generated, be convenient for simultaneously
The production of subsequent product.And the honeycomb core stretched is equal to the honeycomb core being brazed, therefore can directly stove be fitted into aluminium sheet
Soldering, is made product, saves once electrical loss caused by soldering, also simplifies the process for making soldering aluminum honeycomb panel, drop
Low energy consumption.
