What kind of media do you mean by media? Punching machine? Oil press? Different machine tools should adopt different installation methods. If a punch is used for machining, the die shall conform to the stroke and closing height of the punch. The die should have a die handle, which is installed in the mounting hole of the punch slider. The size of the die handle should be the same as that of the mounting hole of the punch slider, and the lower die should be directly pressed on the workbench of the punch. If it is processed by an oil press, the upper die of the die does not need a die handle, and the upper die is directly pressed on the slide block of the oil press with screws and pressure plates, and the lower die is pressed on the fixed table of the oil press.
