1 Improved Design of Stamping Die Stamping die life time is based on rational design.In stamping die design, engineers should give full consideration to form of mold,fixing method and guide form of concave convex die,determination of the pressure center and rigidity of lower plate.Especially for blanking die, gap value has a great influence on the
Metal stamping springback is a difficult problem for the automotive stamping parts.There is not a perfect method to deal with springback of stamping parts.After researching the stamping springback problem,we get following factors: Material performance There are different strengths of automobile stamping parts. from ordinary plate to high strength plate, different plates have different yield strength.
The precision metal terminal inside the connector house is the core part of the connector, which will transmit voltage current or signal of the external power lines or cable to the corresponding contact element matching connector. So, contact structure must be good, stable and reliable contact force and electrical conductivity. Loose contact will exist in
In-die tapping is that a part manufactured out of brass is created using multiple stations in the stamping process. While the stations continue to shape the part as the material moves through the stamping press, holes are tapped to provide the threading necessary for the finished piece. Combining the tapping and progressive die stamping process
Because of different stamping process and different working conditions, the cause of precision stamping die burst can be in many ways. The following aspects of comprehensive analysis of the cause of mold burst: 1. The stamping die with bad raw material will broken in the subsequent processing.The life of molds with different materials is often
1. Pressure injury on mobile phone shield bending internal and external side There are is two kinds of situations: （1）Waste jumping on the small and big hole: Because of Long time producing the of punch and edge waste gap become too big to stuck waste, which will be brought out the punch die face and
At the end of last month, the meeting of the Shenzhen ROBO medical terminal Robot Research Institute showed that China’s single hole medical terminal surgical robot is the development direction of the next generation of robots. Compared with the porous medical terminals surgical robot, single hole will have the advantages of low surgical space requirements,
In recent years, China die industrial have developed rapidly and already have international die tooling technology. The scale of the tooling making is the lead in the world. But it remains at the lower end of the relevant supporting testing technology, monotony and limitation. Traditional test way only can do appearance size, hardness test and so on of the die and products. There is a lack of better testing method of the internal structure and quality, adaptability, risk assessment. In consequence, a convenient a lossless testing way in all directions for interior and exterior of
