Abstract：

The structure design features of double row and no waste of progressive die for ballast were introduced.The layout process for this die was analyzed and the key technology of no waste stamping was resolved. Double row and no waste layout design was adopted. The material utilization and production efficiency were greatly improved. The die has the characteristics of high precision, high speed and long life. The actual use proves that the structural design is reasonable, operation is safe and reliable, and die manufacturing processing is convenient. Mass production needs of ballast blanking piece are satisfied.
