AI Technical Summary
In the cold stamping progressive die for automotive parts, the strip is prone to vibration when the die is opened, which can cause the feeding action to be stuck and the parts to be deformed. Existing technology relies on experience to design additional lifting devices, which increases costs and is not effective.
The first natural frequency of the material strip is calculated by finite element modal analysis, a safety threshold is set, and a quantitative judgment is made on whether and how to add a lifting device to optimize the mold design to reduce the risk of vibration.
It effectively reduces the risk of conveyor belt vibration, reduces redundant design, lowers manufacturing costs, improves production stability and quality, and shortens the design cycle.
