Description
Technical field:
The present invention relates to a kind of shaping dies of high-speed EMUs aluminum profile covering, belong to material forming field.
Background technique:
High-speed EMUs headstock covering outer surface has one through sharp rib, and inner surface has several T shape muscle, as shown in Figure 1, should
Kind of covering is the critical component for determining high-speed EMUs head vehicle shape, forming accuracy directly affect entire headstock precision,
Intensity and aerodynamic performance influence headstock appearance and whole aesthstic design effect.
Body front assembly base material is the aluminium alloy extrusions with T shape muscle, as shown in Fig. 2, using traditional moulds bending process
When forming, since the sharp rib that part is located at below T shape muscle is blocked, die punch can not be contacted and is pressed into below T shape muscle
Type face causes the sharp rib in this part that can not shape, therefore whole sharp rib completely can not be clearly suppressed and, and seriously affects covering
The forming accuracy of part.Conventional solution is will to block swaging again after the T shape muscle excision of sharp rib, but cut off T shape muscle and will lead to and cover
The intensity of cover piece declines to a great extent, and then weakens the intensity of entire headstock.This problem seriously annoyings vehicle manufacturing enterprise, is badly in need of
It solves.
In view of the above problems, first using mould the invention proposes a kind of shaping dies of high-speed EMUs aluminum profile covering
Aluminum profile after heating is bent preform by tool, high temperature high pressure oil is then passed through into mold drip molding is compressed completely and be pasted in
On cavity plate, the essence forming of whole sharp rib is realized, to need when dexterously solving rib sharp using traditional moulds swaging process forming
It cuts off the part T shape muscle of profile, weaken the problems such as its intensity.
Summary of the invention:
Above-mentioned purpose of the invention is realized by the following method, as follows now in conjunction with Detailed description of the invention:

On cavity plate 12, punch-pin 6, which moves downward profile to be pressed on cavity plate 12, completes molding, and ring compression platform 6-1 thereon is profile
Periphery compresses, sealing forms a closed cavity, i.e., bends profile 8 to state as shown in Figure 3, complete preform, then open
Oil inlet switch 3, to the intracavitary injection high pressure hot oil of hermetic type, high pressure hot oil can be completely filled with type chamber around the obstruction of T shape muscle,
Profile compresses be fitted in molding surface completely, after pressure maintaining for a period of time, the sharp rib of complete display can be obtained, until as shown in Figure 4
State realizes sharp rib essence forming, stops oil inlet, and opening unloads oil circuit breaker 2, makes the high pressure oil release that hermetic type is intracavitary, such as Fig. 5 institute
Showing, oil inlet pipe 4 accesses compressed air, and the intracavitary oil of hermetic type is blown out through oil discharge pipe 1 and is emptied, punch-pin 6 is then lifted, is opened,
Take out covering.
Resistance wire 10 is set under the punch-pin 6 of the mold, 12 surface of cavity plate, it can be by heating mould surface to heating
Profile 8 continues heating and thermal insulation, and the profile plasticity under high temperature is good, and resistance of deformation is small, is easy to the precision form of sharp rib；
There is slightly higher ring compression platform 6-1 on 6 periphery of punch-pin of the mold, is slightly less than 1 material with the gap of cavity plate 12
Thickness can be pressed on aluminum profile periphery on cavity plate 12, form hermetic type chamber by sealing firmly, while on ring compression platform 6-1
Heat-resistant sealing ring 6-2 is set, airtightness is further increased by soft seal, what soft, hard dual-seal can guarantee hermetic type chamber can
By sealing, oil leak when preventing subsequent hydroforming；
The mold will first stop oil inlet after pressure maintaining shapes, and then open and unload 2 release of oil circuit breaker, then oil inlet
Pipe 4 accesses compressed air, the intracavitary oil blowout emptying of hermetic type, oil liquid leakage pollution environment when preventing from being opened pickup.
The present invention has the advantage that the aluminum profile 8 after heating is first bent preform with mold, it is then passed through high temperature again
High pressure oil realizes the essence forming of whole sharp rib, to obtain the sharp rib of complete display；Surface is embedded in the punch-pin 6, recessed of resistance wire 10
Mould 12 and high-temperature hot oil can keep the temperature 8 continuous heating of aluminum profile heated, it is made to have the change of good plasticity and very little
Shape drag, it is ensured that the precision form of sharp rib；The soft or hard dual-seal measure of heat-resistant sealing ring 6-2 and ring compression platform 6-1 can be true
Confidential letter is reliable, prevents high pressure hot oil from revealing；It is opened before pickup to seal chamber release and being blown into gas empties oil liquid, it can be to prevent
Only oil liquid outflow pollution environment.
