Types of dies
The type of die and the closely related transportation of the part between
diesis determined in accordance with the forming procedure, the size of
the part in question and the production volume of parts to be produced.
The production of large sheet metal parts is carried out almost exclusively
using single sets of dies. Typical parts can be found in automotive
manufacture, the domestic appliance industry and radiator production.
Suitable transfer systems, for example vacuum suction systems, allow
the installation of double-action dies in a sufficiently large mounting
area. In this way, for example, the right and left doors of a car can be
formed jointly in one working stroke (cf. Fig.4.4.34).
Large size single dies are installed in large presses. The transportation
of the parts from one forming station to another is carried out mechan-
