The device comprises a mold and a plurality of core rods, each core rod is a cylinder, the cross section of which is shaped like a regular hexagon, the core rods can be stacked together, so that the cross section is honeycombed, the mold is a cuboid, the six sides of which can be disassembled, and the interior of the mold is hollow, so that a cavity with a honeycombed profile is formed. The diffusion welding method for honeycombed titanium alloy material and the device thereof, which are provided by the utility model, perfectly solve the problem on how to produce honeycombed titanium alloy material.
Description
Technical field
The utility model relates to the manufacturing field of metal Multifunction composite, relates in particular to a kind of diffusion welding method and device thereof of honeycombed titanium alloy material.
Background technology
The metal beehive material is a kind of Multifunction composite, contain a large amount of linear clear openings in its internal structure, the cross sectional shape in hole has multiple, be optimum with regular hexagon (as the shape of honeybee honeycomb) wherein, the metal beehive material is that a kind of logging material characteristic and macrostructure characteristic are the Multifunction metal material of one, it is good that it has a high-specific surface area, ultralight matter high specific stiffness, thermal diffusivity, permeates architectural characteristics such as through-flow.Titanium alloy more and more is employed owing to its particular performances, especially at aerospace field, the titanium alloy product increases gradually, and aerospace field requirement part has high rigidity, intensity, and pts wt is light again, and the honeycombed titanium alloy material can be good at satisfying this requirement.Yet because the titanium alloy processing difficulties so far, does not also have comparatively feasible honeycombed titanium alloy material preparation method for material and technology.Now usually titanium alloy 3 laminates of research or the SPF/DB technological forming of 4 laminates, there are a lot of problems in resulting structure: the cross sectional shape as the lack of homogeneity of material, honeycomb hole is wayward, the specific stiffness value is less etc.The diffusion welding method of a kind of honeycombed titanium alloy material that the utility model provides and the comparatively perfect solution of device thereof the manufacturing issue of honeycombed titanium alloy material.
The utility model content
The purpose of this utility model is the manufacturing issue that solves the honeycombed titanium alloy material.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of Diffusion Welding device of honeycombed titanium alloy material, it is characterized in that, comprise mould and a plurality of plug, described a plurality of plug is the orthohexagonal cylinder of cross section, a plurality of plugs can pile up cross section mutually and form honeycombed, described mould is six detachable cuboids, and its inner hollow forms the cavity of honeycombed outline.
A kind of diffusion welding method of honeycombed titanium alloy material is characterized in that may further comprise the steps:
The first step utilizes described mould with the preformed of titanium alloy plate, makes its formation have concavo-convex waveform preformed plate, and the sunk part of described preformed plate and the shape of bossing are regular hexagon half,
Second step, cleaning is carried out on the surface of above-mentioned preformed plate, then two preformed plate minute surface symmetrical stack are formed orthohexagonal preformed plate group, more a plurality of described preformed plate groups are piled up formation honeycombed preformed board stockpile,
The 3rd step, above-mentioned preformed board stockpile is put into the mould of suitable this honeycombed profile, place a plug in each sealing hexagon of honeycombed preformed board stockpile, the plug size is coincide with the sealing hexagon, and mandrel surface scribbles solder resist,
The 4th step placed Diffusion Welding equipment with the above-mentioned mould that preformed board stockpile, plug are housed, and connection is spread in the pressurization that heats up, be welded into one, after welding is finished, mould opened, take out plug, just obtain the titanium alloy material that cross sectional shape is favose one.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of Diffusion Welding device of honeycombed titanium alloy material as shown in Figure 4, comprises mould 2 and a plurality of plug 3.As Fig. 1, shown in Figure 4, mould is six detachable cuboids, its inner hollow forms the cavity of honeycombed outline, because titanium alloy superplastic forming and Diffusion Welding need be carried out under 900 ℃ of left and right sides hot environments, so mold materials is had relatively high expectations, take all factors into consideration factors such as performance, price, processing and select for use the 1Cr18Ni9Ti hot-die steel to produce described mould.As Fig. 2, shown in Figure 4, plug 3 is orthohexagonal cylinder for cross section, and a plurality of plugs can pile up cross section mutually and form honeycombed, adopts the hot-die steel material to make plug equally, should consider the thickness effect of plate simultaneously
Produce described plug by size.
A kind of diffusion welding method of honeycombed titanium alloy material may further comprise the steps:
The first step, select the thick TC4 titanium alloy plate of 1mm for use, utilize then mould to TC4 titanium alloy plate in superplastic forming during at 925 ℃ on the superplastic forming machine, make its formation have concavo-convex waveform preformed plate, as shown in Figure 3, the sunk part of preformed plate and the shape of bossing are regular hexagon half, can determine the quantity of preformed plate according to output.
Second step, cleaning is carried out on the surface of above-mentioned preformed plate, then two preformed plate minute surface symmetrical stack are formed orthohexagonal preformed plate group, again a plurality of described preformed plate groups are piled up and form honeycombed preformed board stockpile, the number of plies according to the honeycombed titanium alloy material is piled up, as shown in Figure 4, this example is that 5 preformed plates 1 pile up formation.
The 3rd step, as shown in Figure 4, above-mentioned preformed board stockpile is put into the mould of suitable this honeycombed profile, bonding surfaces is carried out cleaning such as oil removing, the removal of impurity in advance mutually, place a plug in each sealing hexagon of honeycombed preformed board stockpile, the plug size is coincide with the sealing hexagon, and mandrel surface scribbles solder resist.
The 4th step, the above-mentioned mould (shown in Figure 4) that preformed board stockpile, plug are housed is placed in the superplastic forming machine (for prior art equipment), connection is spread in the pressurization back under 925 ℃ temperature, be welded into one, after welding is finished, mould is opened, taken out plug, just obtain the titanium alloy material that cross sectional shape is favose one (as shown in Figure 5).
In actual production, the size of honeycombed structure and the number of plies can be adjusted as required, as descending and both sides increase titanium alloy flat board, can directly produce the honeycombed titanium alloy of integral type sealing thereon
Material, its cross section as shown in Figure 6.
The titanium alloy honeycomb material that uses the above method to make, the plate limit fusion of fitting mutually connects as one, the performance of material greatly improves, can be applied in the manufacturing of the corresponding part of Aero-Space, also can be applied to other such as automobile making, shipbuilding, building, industries such as sports equipment.
Above step and narrating content are further specifying embodiment of the present utility model; and do not mean that the utility model has only these contents; technique change for use method of dealing with problems provided by the utility model and form thereupon should be considered as the utility model rights protection scope.
