Description
Technical field
It is specifically a kind of to be based on stamping forming metal plate plate and its add the present invention relates to metal plate plate stamping technology field
Work technique.
Background technique
Punch forming refers to that depended on pressure machine and mold apply external force to plate, band, tubing and profile etc., is allowed to generate modeling
Property deformation or separation, thus obtain needed for shape and size workpiece (stamping parts) processing molding method.Heat stamping and shaping work
Skill is also hardened at punching press, is one occurred in recent years and is produced the new technology of high-intensitive punch forming part, using heat stamping and shaping
Stamping parts made from technology, intensity may be up to 1500MPa, and be formed at high temperature almost without rebound, common compared at present
Cold-stamped part there are formed precision high, good moldability and the outstanding advantages such as light-weight.
Titanium alloy due to low-density, very high anti-corrosion capability and be widely used in the fields such as aviation, ship, chemical industry,
Its plate can be applied to the conventional parts of 350 DEG C or less work, such as aircraft skin, thermal insulation board, heat exchanger, with work
The continuous development of industry technology and special components constantly being applied in high-end devices, the application field of titanium alloy is also continuous
It expands.Relationship between its punching formation property and material property value, deformation currently are concentrated mainly on to the research hotspot of titanium alloy
The correlation research of mode and sheet fabrication hardening.But because titanium alloy is close-packed hexagonal lattice, plasticity is poor, it is difficult to shape, make
At developing slowly for titanium alloy plate plastic forming technology, its application range is limited.In addition the surface and inherence of Stamping Sheet material
Performance is very big on the influence of the quality of presswork, in existing production method, only to the stamping parts finished product after the completion of production link
It is checked, is partially produced without stamping forming substandard product without detecting same progress punch forming process
Stamping parts finished product is unable to satisfy customer demand, cannot use, and the stamping material after punch forming, can not reuse,
While causing the waste of stamping material, a large amount of production time is occupied, very influence working efficiency.
Summary of the invention
