Press System Description
This chapter will help you become familiar with:
major components of a typical press system
safety requirements for a press system
A press system, as referred to in this manual, includes:
a mechanical power press
an Allen-Bradley clutch/brake controller
all associated control panels and operator stations
all associated output and feedback devices
all wires and cables that interconnect system components
A functional block diagram of a typical press system is shown in
Figure 2.1. This figure shows general relationships between major
components. Specific functional relationships vary according to the
requirements of your particular press system. For details, refer to;
chapters 3 thru 7 of this manual
technical documentation provided by your press manufacturer
ANSI B11.1, American National Standard for Machine Tools,
Mechanical Power Presses, Construction, Care, and Use
Important: Use an Allen-Bradley clutch/brake controller only with a
mechanical power press that has a part-revolution clutch. A
part-revolution clutch can be disengaged at any position of the shaft. This
allows your clutch/brake controller to stop the press at any position. In
contrast, a full-revolution clutch can be disengaged and stop the press
only at the top position of the stroke.
