Dead centres
Positions at which the upper die is located during its movement:
• Bottom dead centre (see Fig. 4, pos. 2.a):
The upper die is closest to the lower die. In general, this corresponds to the
end of the closing stroke.
• Top dead centre (see Fig. 4, pos. 2.a):
The upper die is furthest away from the lower die. In general, this corresponds
to the end of the opening stroke.
Die area (danger zone at the press)
Area between moving dies, moving press slide, moving die cushion and workpiece
ejector.
Die cushion (see , pos. Fig. 4, pos. 5)
Auxiliary device for a lower die that accumulates and delivers or absorbs the
required force for some forming operations with the press.
Gravity-loaded axis
Axes that can make unexpected dangerous movements due to gravity or stored
energy as a result of failures.
Lower die (see Fig. 4, pos. 3)
Fixed part of the die on the clamping plate.
Press slide (see Fig. 4, pos. 4)
Main part of the press that performs the stroke movement and to which the upper
