Description
Technical field
The present invention relates to a kind of mould, particularly a kind of sheet material creep forming mould for metal material processing.
Background technology
Integral panel due to have structure efficiency high, be easy to realize the outstanding advantages such as uniform strength design, good airproof performance, become the important feature part of modern aerospace, communications and transportation Advanced Equipment.But its structure is often more complicated, often there is the features such as the change of profile curvature non-homogeneous continuity, many internal structures, non-uniform thickness distribution.The integral panel component of shaping complex appearance and structure has become one of key technology preparing modern Advanced Aircraft.Integral panel creep forming is the deformation of creep and the ageing strengthening characteristic that utilize metal, by a kind of processing method that the shaping of component and ageing strengthening heat treatment process are carried out simultaneously.The general process that creep forming manufactures wallboard base part is: be placed on by slab and mould seal and is placed in vacuum environment, by equipment such as autoclaves, pressure and temperature are applied to whole sealing frock again, make slab paste mould, and complete heat treatment process, last unloading spring-back, obtains formed parts.Because creep stress is in elastic range, resilience is inevitable, the microstructure and property change of the series of complexes such as the elastic-plastic deformation needing consideration metal stock to occur in whole process when therefore manufacturing creep forming mould and ageing strengthening, repair a die according to calculating simulation design and test of many times result, could finally obtain the mould shape face met the demands, therefore, die trial is very crucial for the satisfactory creep die face of acquisition.
The mould structure form of current creep forming mainly contains what fin-plate type Split type structure two kinds of fixing curvature characteristic overall structure.Obviously, fixing curvature characteristic overall structure is for repeatedly amendment required before component creep forming mould shape, and Mould Machining cost is high, and the design and manufaction cycle is long; Fin-plate type Split type structure mould is compared with fixing curvature characteristic overall structure mould, still need before sizing repeatedly to revise gusset, just reduce the processing capacity of mould during amendment, still need repeatedly to revise gusset mould, cost is still higher, and design, the manufacturing cycle also do not shorten.Because the development of integral panel pursues coarse scale structures day by day, supporting mould also increases thereupon, and the man-hour of die manufacturing cost and the consumption of mould shape adjustment also significantly increases.Therefore, need to reduce die manufacturing cost further, improve die face regulated efficiency.
Summary of the invention
For the deficiency of existing creep forming mould, the invention provides a kind of push rod and the box-like metal creep forming die of shim pack, die face regulated efficiency is higher, processing cost is lower.
Push rod provided by the invention and the box-like metal creep forming die of shim pack, comprise multiple push rod, multiple pad, push rod fixed head and profile backing plate.Described push rod height is all identical, spacer thickness is all identical, or both are in the margin of tolerance allowed.Described push rod comprises shaft and the termination with screw rod, and shaft is provided with the screwed hole matched with screw rod.The orthogonal slot that the transverse and longitudinal that described push rod fixed head face has certain depth is intersected, groove width and push rod shaft match, and push rod shaft is contained in orthogonal slot infall, and pad is arranged in orthogonal slot, below push rod shaft.Described profile backing plate is arranged at above push rod termination.By shim packs being built up the height that different-thickness adjusts roughly push rod, by the screw rod of push rod termination, fine adjustment is carried out to push rod height, to form required push rod array.
As improvement, bottom the orthogonal slot of push rod fixed head, the below of pads placement arranges through hole, is convenient to the taking-up of push rod and pad.
Described pad is "T"-shaped, stackingly to form during use by 1 ~ 10 layer.
Described push rod shaft cross section is " ten " font mated with fixed head orthogonal slot.
Described push rod termination is that semicircle is spherical.
Described profile backing plate is the thin plate of aluminium, steel or steel combined with aluminum.
Technique effect of the present invention is: 1. mould structure is simple, and all parts difficulty of processing is little, and wherein push rod and pad also can batch micro operations and reusing, and therefore die cost significantly reduces.2. the combination of push rod and pad can obtain dot matrix height roughly, in the fine setting by push rod termination screw rod, not only can realize the accurate control of dot matrix profile, and easy to operate, improves die face regulated efficiency.3. push rod can coordinate well with the orthogonal slot of push rod fixed head, plays location and firm effect.
Mould provided by the present invention is applicable to the through engineering approaches experimental study of large-scale workpiece creep forming and small batch is produced, the processing cost that not only can avoiding repairs a die in experimentation repeatedly brings and R&D cycle problem, and can ensure that drip molding surface wave degree is less than 0.5%.

Detailed description of the invention
See Fig. 1, the present invention includes multiple push rod 2, multiple pad 4, push rod fixed head 1 and profile backing plate 5.Push rod fixed head 1 is provided with the orthogonal slot 3 (as shown in Figure 2) that transverse and longitudinal is intersected, and for the position of fixed mandril 2, the thickness of push rod fixed head 1 is 10 ~ 1200mm, and orthogonal slot 3 is 5 ~ 1000mm deeply, and the width of orthogonal slot 3 is 5 ~ 200mm.The bottom of orthogonal slot 3 arranges through hole 6 at the place-centric of each placement push rod 2, and aperture is 0 ~ 150mm, facilitates the taking-up of push rod 2 and pad 4.
As shown in Figure 3, the cross section of top body 7 is " ten " font mated with fixed head orthogonal slot to push rod 2, and path length is 10 ~ 300mm, is highly 5 ~ 2000mm.The entirety that push rod termination is made up of semiglobe 8, cylinder changeover portion 9 and screw rod 10, hemisphere 8 diameter is 10 ~ 300mm, and cylinder changeover portion 9 axial length is 10 ~ 30mm, and screw rod 10 diameter is 5 ~ 200mm, and screw rod 10 length is 5 ~ 100mm.The center distance of adjacent push rod 2 is 10 ~ 800mm.
Pad 4 is "T"-shaped, and thickness is 10 ~ 500mm, stackingly can to form during use by 1 ~ 10 layer.Push rod 2 and pad 4 are the fixing standard components of a series of size, and they can batch micro operations storing for future use.
Be covered with one deck profile backing plate 5 above push rod 2 array, for being required smooth surface by the transition of discrete point front, profile backing plate can be that aluminium sheet, steel plate or Steel-aluminium composite board etc. are easily deformable but can not destroy the sheet material of required smooth surface.
The present invention adopts the profile backing plate contacted with described push rod 2 dot matrix to realize the continuously smooth profile of designed mould.By selecting suitable push rod 2 spacing and profile backing plate 5 thickness, the impression that profile backing plate can be made to have enough rigidity cause to resist push rod 2 local action, also can improve subsides and imitate fruit, reduce the surface contour error of formed parts.
