Abstract
This utility model is related to a kind of section bar of processing empennage, belongs to empennage manufacture field.Empennage section bar of the present utility model, described section bar is the grade arris tubular construction of both ends open, the length of this rib cylinder is matched with the multiple of empennage product length, inner side plate face and outside plate face mating shapes all with empennage product for the profile in each bar tetragon side wall of this rib cylinder.Empennage section bar of the present utility model, not only increases the stock utilization of processing empennage, and improves working (machining) efficiency, reduce manufacturing cost.
Description
Technical field
This utility model is related to a kind of section bar of processing empennage, belongs to empennage manufacture field.
Background technology
The aluminium alloy empennage processing method of existing rocket mainly has the following two kinds.
First, using aluminium sheet integrated machine addition shape, the method has the disadvantage that：
1) easily deform.Because 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) because allowance is big, lead to tool wear in the course of processing to increase, improve processing cost.3) material profit
Low with rate.4) process-cycle is long, and efficiency is low.
Second, application aluminium alloy warm extrusion technology by the blank of aluminium sheet forward extrusion one-tenth and tail structure adjoining dimensions, so
Machine add-on type more afterwards.The method has the disadvantage that：
1) this processing method can only extrude a blank every time, and the working (machining) efficiency of blank is also than relatively low.2) the method adopts
Forward extrusion method, the extruding force of needs is higher, and power consumption is big.
For disadvantages mentioned above, need to find a kind of new not only can improving stock utilization but also working (machining) efficiency can be improved also
The processing to carry out empennage of the blank manufacture method of manufacturing cost can be reduced.
Utility model content
The purpose of this utility model be exactly in order to solve traditional aluminium alloy empennage processing technique exist stock utilization low, plus
Work efficiency rate is low, high processing costs the shortcomings of, and provide a kind of processing empennage section bar.
The purpose of this utility model is achieved through the following technical solutions：
A kind of section bar of processing empennage of the present utility model, described section bar is the grade arris tubular construction of both ends open, should
The length of rib cylinder is matched with the multiple of empennage product length, in each bar tetragon side wall of this rib cylinder profile all with empennage product
Inner side plate face and outside plate face mating shapes.
The structure of described section bar adopts rods and bars of aluminium alloy extrusion molding.
Described profile applications method, comprises the following steps that：
1) cut length：
Along vertical section bars axis direction, section bar is cut into the blank that every segment length is matched with empennage product length.
2) singulation part
By step 1) every section of blank obtaining axially cuts along the joint of tetragon side wall, forms each profile consistent
Empennage blank.
3) polish
By empennage finished product consistent with empennage product for each empennage blank machine addition profile.
Beneficial effect
Empennage section bar of the present utility model, not only increases the stock utilization of processing empennage, and improves processing effect
Rate, reduces manufacturing cost.
Brief description
Fig. 1 is the front view of this utility model empennage section bar；
Fig. 2 is the left view of this utility model empennage section bar.
Specific embodiment
With reference to the accompanying drawings and examples content of the present utility model is further described.
Embodiment
A kind of section bar of processing empennage of the present utility model, as shown in Figure 1, 2, described section bar is to be squeezed using rods and bars of aluminium alloy
The equilateral six rib tubular constructions of the both ends open of pressing formation, the length of this six ribs cylinder is matched with 2 times of empennage product length, should
Inner side plate face and outside plate face mating shapes all with empennage product for the profile in each bar tetragon side wall of six rib cylinders.
Described profile applications method, comprises the following steps that：
1) cut length：
Along vertical section bars axis direction, section bar is cut into the blank that two segment length are matched with empennage product length.
2) singulation part
By step 1) every section of blank obtaining axially cuts along the joint of tetragon side wall, forms six profiles consistent
Empennage blank.
3) polish
By empennage finished product consistent with empennage product for six empennage blank machine addition profiles.
