[0032] After the stamping of the single-project hardware stamping die is completed, the product 27 of the reverse cutting and blanking will move upward for a distance synchronously with the upper die, and the disengagement device of the upper die will remove it from the concave model cavity 18 of the upper die, and it will fall downward. At this time, since the receiving box 1 is driven by the receiving drive device to extend into the stamping die and is located directly below the concave model cavity 18 of the upper die, the fallen product 27 is just caught by the receiving box 1. When the die is fully opened, the worker puts a sheet metal material tray with punching into the lower die, and the waste material on the lower die is ejected. The upper die descends and enters the next product 27 punching and forming process. At the same time, the receiving box 1 is driven by the receiving drive device to withdraw from the outside of the stamping die, so as to realize the automatic material collection of the product 27, and there is no need for workers to take materials from the stamping die.
