AI Technical Summary
In the existing technology, during the use of vehicle longitudinal beam molds, it is difficult to achieve precise positioning and efficient buffering, which leads to mold wear and affects production efficiency and lifespan.
A vehicle longitudinal beam stamping die was designed, which includes a positioning mechanism and a buffer mechanism. The positioning mechanism achieves precise positioning through positioning blocks and positioning shafts, and absorbs impact force by combining buffer springs and buffer columns to reduce die vibration.
It achieves precise positioning and stability of the mold, reduces mold wear, and improves production efficiency and mold life.
