2、 Classification by operation combination degree
According to the classification of different process combinations, stamping dies are divided into single process die, compound die, progressive die and transfer die.
1. Single process die
Single process die refers to the die that can only complete one stamping process during the working process of the press.
2. Compound die
In one stroke of the press, the compound die can complete two or more stamping processes at the same station at the same time.
3. Progressive die
Progressive die is also called continuous die. This kind of die has two or more stations and can complete two or more stamping processes at different stations.
4. Transfer mode
The transfer die can be transferred by a manipulator, which greatly improves the production efficiency, reduces the manufacturing cost and saves the material cost. The transfer die integrates the advantages of single process die and progressive die, and has the characteristics of quality safety, stability and reliability.
