what is the purpose of the two "spring shafts" in the background of the form? is it to assist with lifting the ram? or some other purpose?
My best guess would be "Limiters" for how far the press ram moves. Only a guess as I don't see enough of the mechanism.
They are called guide pins and keep the top shoe in exact alignment with the bottom shoe of the die. In this case, they have ball bearing sleeves on the guide pins to reduce friction and make the die last longer. The springs keep the sleeves up at the top to catch the guide bushings every time. Without the springs, the sleeves would just fall to the bottom and stay there. The punch press regulates how far down the top shoe of the die goes. There is an adjustment screw on the press to set the depth.
yes guide pins. the center of the die moves down & up.
