Description
Technical field
The utility model relates to a kind of punching compound die location building mortion of aviation support, belongs to stamping technology field.
Background technology
At present aviation support generally adopts titanium alloy to make, and titanium alloy, compared with other structural metals, has the remarkable advantages such as intensity is high, corrosion resistance is strong, high temperature performance is good and higher fatigue resistance.But the processability of titanium alloy is only the 20-40% of 45# steel, in the time of the hardness <HB300 of titanium alloy, there will be strong sticky cutter phenomenon, and hardness >HB370 makes processing difficulties too firmly.
The aviation contoured cradle of existing titanium alloy is unique, generally adopts hydroforming to make, but processing is very difficult.Than aviation support as shown in Figure 2, its blank needs bending just can complete for 3 times, and in the process of hydroforming, the each bending of the blank of aviation support all needs different moulds, and need to increase positioner, sometimes also needs location.Nonetheless, the positioning precision of the aviation support to unique profile is as shown in Figure 2 still very poor, and if employing rubber pocket shaped by fluid pressure can cause again very large resilience.Therefore, at present aviation support is carried out all needing to correct shape after hydroforming, it is generally poor by machined correction positioning precision and the large caused error of resilience, in the time of machined, position also pretty troublesome to thering is the aviation support of unique profile, so not only workload is very large, and has further increased processing cost.
Utility model content
The technical problems to be solved in the utility model is: propose that a kind of the need aviation support that repeatedly bending could form is only needed to hydraulic pressure is shapable compound die location building mortion, this device not only can improve the positional precision of bending part, and can save the machined school shape process after hydroforming.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of punching compound die location building mortion of aviation support, comprise base plate and the upper die and lower die that are oppositely arranged, described counterdie comprise be arranged on base plate one end baffle plate, be arranged on the fixing counterdie of the base plate other end and be arranged on baffle plate and fixing counterdie between and be close to the movable counterdie of baffle plate and fixing counterdie, between described movable counterdie and base plate for elasticity is connected; The bottom of described patrix is shaped with the first shaping notch, and the top of described fixing counterdie is shaped with the second shaping notch corresponding with the first shaping notch.
Like this, in the time of described upper die and lower die matched moulds, a part for the blank of aviation support is first clamped by the baseplane of described patrix and movable counterdie end face, along with moving down of described movable counterdie, described the first shaping notch and the second shaping notch each other to interlock by stamping another part of the blank of described aviation support.
For the ease of before matched moulds, the blank of aviation support being positioned, the end face of described fixing counterdie is provided with the banking stop blank of described aviation support being positioned when before described upper die and lower die matched moulds.
As preferred version, the described baffle plate of described the second shaping notch distance is certainly as far as being closely sagging successively stairstepping; Described upper die and lower die are in the time of matched moulds, and described patrix and movable counterdie clamp after the blank of aviation support, and described patrix continues the lower aviation support blank of exercising and produces plastic deformation, thereby makes the aviation support of reservation shape.
As preferred version, described the second shaping notch is two rank stairsteppings; After described upper die and lower die matched moulds, the end face of described movable counterdie is lower than minimum cascaded surface in described fixing counterdie.
As preferred version, between described movable counterdie and base plate, be connected by Compress Spring.
The course of work of the punching compound die location building mortion of aviation support of the present utility model is as follows: described patrix is fastened on press ram, can do upper and lower reciprocating motion with slide block; When work, the blank of aviation support positions by the banking stop of fixing counterdie end face; In the time of matched moulds, first described patrix and movable counterdie contact and clamp the blank of aviation support, for the follow-up hydroforming of the blank of this aviation support provides pre-determined bit; Patrix continues descending, and blank produces plastic deformation, makes the aviation support of reservation shape.
The beneficial effect that the utility model brings is: the punching compound die location building mortion of aviation support of the present utility model, in the time of upper die and lower die matched moulds, described patrix and movable counterdie provide pre-determined bit for the follow-up hydroforming of aviation support blank, like this in the time manufacturing the need aviation support that repeatedly bending could form, compare traditional process for stamping and forming, only need a hydroforming can produce qualified part, not only no longer need many molds, and saved the complexity location in the time that mould switches, thereby improve the positioning precision of bending part.
In addition, the punching compound die location building mortion of aviation support of the present utility model no longer needs complicated machined to correct shape after hydroforming, only need carry out simple machined by the blank before punch forming, and blank before punch forming not yet passes through bending, shape is relatively simple, therefore not only significantly improve production efficiency, and greatly reduced mach difficulty.
