Description
Technical field
The utility model belongs to carbon fibre material field shaping technique, is specifically related to a kind of carbon fiber type board forming die.
Background technology
Carbon fibre material has the features such as intensity height, light weight, is therefore widely used in aeronautical material.In prior art, carbon fibre material the most all uses the most hot-forming, but, due to the physical property that carbon fibre material is unique, in hot pressing, the very fast deformation of template corner can cause template corner easily to produce solid accumulation phenomenon, causes template in uneven thickness, thus affects the Forming Quality of carbon fiber template.
Utility model content
The purpose of this utility model is to provide a kind of carbon fiber type board forming die being able to ensure that carbon fiber template each position uniform wall thickness.
For achieving the above object, the utility model provides techniques below scheme:
A kind of carbon fiber type board forming die, it is planar strip platy structure before the shaping of described template, it it is cross sectional shape consistent strip template in each position after shaping, including the first module and the second module, described first module includes the first punch and the first die that mutual folding arranges, described first punch and the first die are strip structure, the cross sectional shape of the first punch and the first die wherein one end is close to the cross sectional shape before template shaping, the cross sectional shape of the other end is close to the cross sectional shape after template shaping, and seamlessly transits for gradual change type between two end sections；Described second module includes the second punch and the second die that mutual folding arranges, described second punch and the second die are the strip structure that each position cross sectional shape is consistent, and second the cross sectional shape of punch and the second die consistent with the cross sectional shape of the template after shaping, the center line of described second punch and the center line of the second die and the first punch and the first die is located along the same line, and the second punch and the second die are positioned at the first punch and the first die cross section close to one end of template after shaping；It is equipped with the heater for die face is heated in described first module and the second module.
Of the present utility model having the technical effect that uses gradual change type hot-forming, making carbon fiber sheet deform several times, progressively close to the desired section shape of template, the material enabling template turning to go out repeatedly is redistributed, avoid solid accumulation, so that it is guaranteed that template each position uniform wall thickness.

Detailed description of the invention
As shown in Figure 2, a kind of carbon fiber type board forming die, it is planar strip platy structure before described template L shaping, it it is cross sectional shape consistent strip template in each position after shaping, including the first module 10 and the second module 20, described first module 10 includes the first punch 11 and the first die 12 that mutual folding is arranged, described first punch 11 and the first die 12 are strip structure, the cross sectional shape of the first punch 11 and first die 12 wherein one end is close to the cross sectional shape before template L shaping, the cross sectional shape of the other end is close to the cross sectional shape after template L shaping, and seamlessly transit for gradual change type between two sections；Described second module 20 includes the second punch 21 and the second die 22 that mutual folding is arranged, described second punch 21 and the second die 22 are the strip structure that each position cross sectional shape is consistent, and second punch 21 and the cross sectional shape of the second die 22 consistent with the cross sectional shape of the template L after shaping, the center line of described second punch 21 and the center line of the second die 22 and the first punch 11 and the first die 12 is located along the same line, and the second punch 21 and the second die 22 are positioned at the first punch 11 and the first die 12 cross section close to one end of template L after shaping；It is equipped with the heater for mould is heated in described first module 10 and the second module 20.The temperature when mould that the utility model provides, temperature when it is preforming and shaping is slightly different, therefore, in order to avoid producing heat transfer between upstream and downstream, it is necessary to be divided into two set modules to carry out preforming and molding procedure respectively.Concrete forming temperature, depending on the specification, thickness of template.
An embodiment of the present utility model is: as shown in figures 3-8.Cross section after described template L shaping is U-shaped, the cross sectional shape of described first punch 11 and the first die 12 is rectangle and top side is provided with fillet, the width of described first punch 11 and the first die 12 is gradually reduced to the other end from wherein one end, and the radius of described fillet is gradually reduced to one end that width is less from one end that width is bigger；The cross sectional shape dress of described second punch 21 and the second punch 22 is rectangle, and described second punch 21 and the second die 22 are positioned at first punch 11 and one end of the first die 12 narrower width.
A kind of method using described mould molding carbon fiber template, comprises the steps:
1. the carbon fiber sheet of planar strip tabular is preheated, make sheet material soften；
2. the carbon fiber sheet after softening sends into the first module 10, carries out preforming, and now the heater of the first module 10 keeps heated condition；
3. opening the first module 10, continue carbon fiber sheet to be fed forward a segment distance, the first module 10 the most again should be closed, and so forth by this distance less than the 1/2 of the first module 10 length；
4. the second module 20 and the first module 10 synchronous on-off, the carbon fiber sheet of the first module 10 end output enters the second module 20 and carries out secondary reshaping, and during this, the heater of the second module 20 keeps heated condition；
5., when the second module 20 discharge end outputting material reaches certain length, cut at this discharge end, obtain carbon fiber template L.
The utility model uses gradual change type hot-forming, makes carbon fiber sheet deform several times, and progressively close to the desired section shape of template, the material enabling template turning to go out repeatedly is redistributed, it is to avoid solid accumulation, so that it is guaranteed that template each position uniform wall thickness.
