3 Fundamentals of press design

Presses used for solid forming
6.8.4 Supplementary equipment
A large number of special measures and equipment are available to address
ever more stringent demands for maximum possible production
outputs, low set-up times and the minimum achievable manufacturing
costs. The most important elements here are systems for the automatic
loading and transfer of parts through various die stations.
Loading systems for blanks and pre-formed workpieces
Where parts weighing less than 150 g are produced, presses are generally
loaded using vibration feeding devices which are filled using inclined
conveyors. Heavier parts are generally fed using inclined conveyors
with rotating steel belts or – in particular where pre-formed parts are
being fed – by means of pushing conveyors. The outfeed area of these
systems is equipped with devices for part orientation to ensure that the
parts are correctly aligned when they enter the in-feed channel and the
loading station (Fig. 6.8.10).
