Workpiece design, layout bead 92-- ＞ calculate workpiece blank size -- it is hot press-formed that ＞ completes workpiece -- ＞ workpiece
Detection -- ＞ conclusions
IIth, operating procedure
A, the analysis of workpiece drop stamping Deformation Reasons：There is necking knot in the two ends for having two U-shaped reinforcements, reinforcement on workpiece
Structure, during hot-forming, with the deformation of plate, necking position shapes under the extruding of punch-pin, due to necking position knot
Structure is asymmetric, makes part each position distortions in forming process uneven, necking position stress concentration.Terminate in sheet forming
When, as external load disappears, the release of distortional stress, and then part may be made to deform.Further, since design of part
Asymmetry, during hot-forming part is cooled to room temperature, different parts cooling velocity is different, it is also possible to cause part to occur
It is serious to become warpage shape.
B, formulation solution：There is the possible cause of serious buckling deformation according to part, take and do not changing part knot
In the case of structure, performance, on part design, layout bead 92, grope bead 92 design, be laid out it is hot-forming to part
Influence.

Meet the hot press-formed of the high-strength steel part workpiece after design, layout bead 92；
3. workpiece blank size, is calculated according to the high-strength steel part workpiece figure being laid out after bead 92, and completes workpiece
The preparation of blank；
4. workpiece blank, is put into heating furnace to be heated, is heated to be adapted to hot press-formed temperature, the timing of insulation one
Between；
5., the hot stamping forming die after improvement is arranged on hydraulic press, upper die plate 1 is fixed on pressing plate, bolt
On hydraulic press upper table table top, lower template 6 is fixed on hydraulic press lower table table top with pressing plate, bolt；Mould installion
Shi Yaoqiu adjusts the gap of mould.
6. the workpiece blank that, would be heated to hot press-formed temperature is transferred on mould from heating furnace, and puts mould
In cavity plate plane, had good positioning workpiece blank position according to location-plate 7, start hydraulic press, mould upstream point is made in oil pressure Oil cylinder
Moved downward under, with mould upstream point operation downwards, mould upper and lower part is gradually fitted, then, in mould upper and lower mould
Swaging is completed under collective effect.Pressurize 5 minutes in a mold after matched moulds, then part is taken out from mould be placed on it is cold on platform
But；
7., after workpiece cooling and shaping, bead 92 is removed by simple operations.
This processing unit (plant) is novel, simple, can effectively prevent that buckling deformation occurs when part is hot press-formed, it is ensured that shaping
The quality of part.The mentality of designing of this processing unit (plant) can as a kind of asymmetrical high-strength steel part it is hot press-formed during prevent
Only there is the typical case of buckling deformation in part, edifies professional and makes a series of reference and extension.
