Description
Technical field
The utility model belongs to mould technical field, and in particular to a kind of eccentric swage of hot forming tool and thermoforming
Mould.
Background technology
Due to the fast development of auto industry, the application of automotive light weight technology and high-strength steel is increasingly becoming developing direction, makes
Vehicle body parts and reinforcer are manufactured with high-strength steel sheet, the intensity of bodywork component can be significantly improved, strengthen car crass
Security performance, while the usage amount of parts material can also be reduced, car body weight is reduced, so as to automobile lightweight.Using
During traditional cold punching technology, because the raising of armor plate strength causes its processability to reduce, resilience is serious, dimension control
Difficulty, therefore the processing technology requirement of high-strength steel sheet can not be met, particularly with intensity more than 1000MPa and geometry compared with
Complicated part, traditional cold punching technology can not be almost molded to part.Heat stamping and shaping technology is a kind of special use
In the forming method of manufacture high-strength steel plate stamping part, its cardinal principle is that steel stamping part is previously heated into austenitizing temperature
More than degree, then rapid shaping quenches simultaneously in a mold, to obtain the high-strength steel member with uniform martensitic structure.Cause
This, heat stamping and shaping technology is increasingly becoming the research and development focus of auto industry.
Hot stamping die has shaping and Cooling Quenching function concurrently, is the key for determining heat stamping and shaping technology success or failure.For example,
Chinese patent literature CN104998967A discloses the thermoforming control mould and control method of a kind of formation of martensite completely, described
