Abstract
The present invention relates to a kind of aluminium alloy empennage high-volume processing method, belong to empennage manufacture field.The empennage processing method of the present invention, is first heated to blank and mould the phase transition temperature of blank, is incubated more than two hours；Then by extrusion die, aluminum alloy blank is squeezed into empennage section bar, described empennage section bar is the arris tubular construction such as grade of both ends open, the length of this rib cylinder matches with the multiple of empennage product length, in each bar tetragon sidewall of this rib cylinder profile all with interior plate face and the outer panel face mating shapes of empennage product；Again the empennage section bar extruded is carried out solid solution and Ageing Treatment；Finally by empennage finished product consistent with empennage product for empennage section bar machine addition profile.The empennage processing method of the present invention, it is achieved that the processing to empennage section bar can realize the once-forming of more than one piece empennage blank, not only increases the stock utilization of processing empennage, and improves working (machining) efficiency, reduce manufacturing cost.
Description
Technical field
The present invention relates to a kind of aluminium alloy empennage high-volume processing method, belong to empennage manufacture field.
Background technology
The aluminium alloy empennage processing method of existing rocket mainly has the following two kinds.
First, use aluminium sheet integrated machine to add shaping, the method has a disadvantage in that
1) easily deform.Owing to surplus is very big, after completion of processing, the stress of remaining is big, and the empennage being therefore processed into is easy to
Deformation occurs.
2) big due to allowance, cause tool wear in the course of processing to increase, improve processing cost.
3) stock utilization is low.
4) process-cycle is long, and efficiency is low.
Second, application aluminium alloy warm extrusion technology is by the blank of aluminium sheet forward extrusion one-tenth Yu tail structure adjoining dimensions, so
After machine add-on type again.The method has a disadvantage in that
1) this processing method can only extrude a blank every time, and the working (machining) efficiency of blank also ratio is relatively low.
2) the method uses forward extrusion method, and the extruding force of needs is higher, and power consumption is big.
For disadvantages mentioned above, need to find and a kind of new not only can improve stock utilization but also working (machining) efficiency can be improved also
The blank manufacture method of manufacturing cost can be reduced to carry out the processing of empennage.
Summary of the invention
The purpose of the present invention is contemplated to solve conventional aluminum alloy empennage processing technique and has that stock utilization is low, add work efficiency
The shortcomings such as rate is low, processing cost is high, and a kind of aluminium alloy empennage high-volume processing method is provided.
It is an object of the invention to be achieved through the following technical solutions:
A kind of aluminium alloy empennage high-volume processing method of the present invention, concrete processing method is as follows:
1) aluminum alloy blank and mould are heated uniformly to 480 ± 5 DEG C at electric furnace, are incubated more than two hours；
2) by extrusion die, aluminum alloy blank being squeezed into empennage section bar, described empennage section bar is the equilateral of both ends open
Rib tubular construction, the length of this rib cylinder matches with the multiple of empennage product length, inside and outside each bar tetragon sidewall of this rib cylinder
Shape all with interior plate face and the outer panel face mating shapes of empennage product；
3) the empennage section bar extruded is removed from the molds, at 497 ± 3 DEG C, is incubated 50～70min, then 30
～place more than 120 hours under the conditions of 60 DEG C of water-cooleds；
4) along vertical tail section bar axis direction, empennage section bar is cut into what two segment length and empennage product length matched
Blank；Then every section of blank is axially cut along the joint of tetragon sidewall, form the empennage blank that each profile is consistent；?
After by empennage finished product consistent with empennage product for each empennage blank machine addition profile.
Beneficial effect
The empennage processing method of the present invention, it is achieved that the processing to empennage section bar can realize more than one piece empennage blank once
Shaping, after shaping, mechanical property meets product design requirement.The empennage processing method of the present invention not only increases processing empennage
Stock utilization, and improve working (machining) efficiency, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the empennage section bar front view that processing method of the present invention obtains；
Fig. 2 is the empennage section bar left view that processing method of the present invention obtains.
Detailed description of the invention
With embodiment, present disclosure is further described below in conjunction with the accompanying drawings.
Embodiment
A kind of aluminium alloy empennage high-volume processing method of the present invention, concrete processing method is as follows:
1) aluminum alloy blank and mould are heated uniformly to 480 ± 5 DEG C at electric furnace, are incubated two hours；
2) by extrusion die, aluminum alloy blank is squeezed into empennage section bar, its structure as shown in Figure 1, 2, described empennage type
Material is the equilateral six rib tubular constructions of both ends open, and 2 times of the length of this rib cylinder and empennage product length match, this rib cylinder
In each bar tetragon sidewall profile all with interior plate face and the outer panel face mating shapes of empennage product；
3) the empennage section bar extruded is removed from the molds, at 497 ± 3 DEG C, is incubated 60min, then at 40 DEG C of water
Place 120 hours under cool condition.
4) along vertical tail section bar axis direction, empennage section bar is cut into what two segment length and empennage product length matched
Blank；Then every section of blank is axially cut along the joint of tetragon sidewall, the empennage blank that six profiles of each formation are consistent；
Finally by empennage finished product consistent with empennage product for each empennage blank machine addition profile.
The empennage finished product obtaining embodiment carries out mechanics property analysis, analyzes testing result and is:
Tensile strength Rm is between 410～475MPa, and percentage elongation A, between 13～18%, meets product design requirement (Rm
>=390MPa, A >=10%).
