Abstract
The utility model relates to a superplastic flatulent forming die, in particular to a large scale superplastic flatulent forming die made of high strength aluminum alloy, which comprises a moving die and a static die. A metal sealing layer arranged on the sealing surface of the static die is semisolid during the forming process of workpieces. In the large scale superplastic flatulent forming die, the continuous sealing performance of the superplastic flatulent forming mould is ensured during the production process, therefore, the superplastic flatulent forming mould has the advantages of safety, reliability, economy and convenience, is superior to other sealing methods, and solves the technical problem that the sealing structure of the prior superplastic flatulent forming mould can not satisfy the sealing requirements of the forming process of the large-scale workpieces.
Description
Technical field
The utility model relates to a kind of superplastic gas bulging forming die, particularly a kind of high strength alumin ium alloy large-sized superplastic gas bulging forming die.
Background technology
The aluminium alloy plate superplastic forming die of Any shape all will be considered design of Sealing Structure, adopting methods such as sealing ring, seal groove is conventional way, but, in hot conditions, when being used for the machining large workpiece, during such as the super 2m of length of mould, wide super 1m, in open and close movement continuously, the hermetically-sealed construction of this routine does not just satisfy the seal request of technology.Particularly to the sealing of 3D (three-dimensional) complex profile, hermetically-sealed construction is in various zone and different positions, under high temperature and gas pressure, makes the matched moulds sealing condition of each point that change take place, in a single day gas pressure will cause above local weak area sews, and causes the forming technology failure.
The utility model content
The technical problems to be solved in the utility model is: the technical problem of seal request that can't satisfy the moulding process of large-scale workpiece for the hermetically-sealed construction that solves existing superplastic gas-bulging mould, the utility model provides a kind of high strength alumin ium alloy large-sized superplastic gas bulging forming die, and it can guarantee mould continuous sealing in process of production.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high strength alumin ium alloy large-sized superplastic gas bulging forming die, it has dynamic model and quiet mould, be provided with the layer of metal sealant on the sealing surface of quiet mould, this metal sealant is semisolid in the Workpiece shaping process.
The beneficial effects of the utility model are, high strength alumin ium alloy large-sized superplastic gas bulging forming die of the present utility model, and under hot conditions, the wriggling of the metal of metal sealant makes the weak area of sealing obtain replenishing and gas pressure balancing, has avoided gas leakage; The metal of metal sealant is semisolid in the Workpiece shaping process, and its wriggling does not influence the additional motion of seal area Workpiece shaping metal; This sealing means can not change sealing state because of working continuously.The utility model has guaranteed superplastic gas bulging forming die continuous sealing in process of production, and is safe and reliable, and economy is convenient, is that other encapsulating methods are unrivaled.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure: 1. dynamic model, 2. quiet mould, 3. workpiece, 4. metal sealant.
The specific embodiment
The embodiment of high strength alumin ium alloy large-sized superplastic gas bulging forming die of the present utility model as illustrated in fig. 1 and 2 has dynamic model 1 and quiet mould 2, is provided with layer of metal sealant 4 on the sealing surface of quiet mould 2, and this metal sealant 4 is semisolid in the Workpiece shaping process.
Trapezoidal mould seal groove in the present embodiment, though its structural design process very under the ideal situation owing to be in different size (x, y, z direction) on the position, suffered temperatures involved district, temperature rise speed (heat conduction) situation difference, influenced the groove gap, thereby made the local pressure difference of form metal, particularly Δ district, though it is very little that design tolerance requires, but under the situation of being heated, produced warm change, the tolerance clearance scope is strengthened.Owing to be the hot shaping of metal down, be in the differing heights size positions, with the dimensional tolerance of 3D processing,, under Linear Temperature change situation, still can not finely coincide even reached minimum.
Characteristics according to the high slight aluminium alloy plate superplastic forming die of big-size complicated shape, it is to be the additional motion that semisolid, its wriggling in the Workpiece shaping process can not influence seal area Workpiece shaping metal as the metal of metal sealant 4 at this metal sealant 4 in the Workpiece shaping process that the metal material of metal sealant 4 is selected to require, such as, the material of metal sealant 4 can be selected aluminum or aluminum alloy.The utility model has guaranteed superplastic gas bulging forming die continuous sealing in process of production, and is safe and reliable, and economy is convenient, is that other encapsulating methods are unrivaled.
