Realistically, we focus on to discuss the way that two kinds of terminal stamping die failure: 1, the plastic deformation failure is mainly due to the terminal stamping die material strength level;
And the heat treatment process is not correct, failed to achieve the best strong toughness steel;
The mold use undeserved cause local overload occurs;
For hot-work mold high temperature softening can also lead to mold thermoplastic deformation failure.
Plastic deformation failure can lead to mold deformation, thus ultimately affect the quality of forgings.
2, terminal stamping mould wear failure caused by stamping tool wear the root cause of the failure is the friction between the mould and billet.
But the particular form of wear and tear and wear process is related to many factors;
Die in the process of working pressure, temperature, billet deformation velocity and lubrication condition, etc.
For hot-work die, due to the cavity surface softening under high temperature wear resistance drop, plus the scale itself also have the effect of abrasive, it determines the wear process is more complicated.
Terminal stamping tool wear failure produced mainly resulted in the forging die wear, affect the precision forgings.
More than 20 years experience of terminal stamping mold design team of engineers, break through the stamping industry technical difficulties, but production mould automatic riveting pieces, automatic mould tapping parts, precision stamping mould injection terminals, etc.
