Background

In the conventional continuous die maintenance (fig. 1), if the inner part of the die needs to be replaced, the upper die part and the lower die part of the die need to be clamped first, and then the fixing device of the die on the punch is taken down. After the die is completely separated from the punch, the die is moved to a die repairing area by using a forklift or a crane, the die plate of the upper die is separated, and the part needing to be replaced is taken out. And after the new part is installed, assembling the template. After the die assembly of the upper die and the lower die is completed, the die is moved to the table top of the punch press by a crane or a forklift, and finally the die is fixed on the punch press again. In the process, the operation of operators is tedious, the mold is heavy, and the time and effort are long and laborious.

The traditional progressive die is characterized in that parts are all embedded in a die plate, a punch is positively locked, and a stripper plate feeding block is positively hung on a stripper plate.
