Powered press brake
|
There
are four basic types of press brakes:
These metalworking machines form parts
through the use of dies attached to a plate type ram or slide
and a plate-type bed. They are mechanically or
hydraulically powered and are primarily used for bending and
forming sheet metal. Metalworking occurs by placing stock on a
bottom die and striking it with a top die attached to the
movable ram.
Operator Involvement
The operator will select and install the dies, place and
position the stock between the dies, activate the press cycle with palm
buttons or a foot switch, and remove the completed part. These
machines are normally used for prototype and semi-production
processes where maximum operator involvement is required, creating
many operational hazards.
Point of Operation |
Potential Hazards:
-
Although most press brake operations do not
require the operators to place their hands or any part of their
body into the point of operation, exposure to point of operation
injuries still exists. Sometimes as the piecepart bends up, a
hazard may be created between the part and the front face of the
slide.
-
Operating controls, especially foot pedals,
introduce the possibility of
accidental cycling.
-
In forming large pieces, the operator must hold the
stock and cycle the press with a foot
pedal. As the work
stroke begins, the stock will move up or down, creating
a hazard.

Press brake safeguarding can be accomplished by

Safety Measures |
Potential Hazards:
-
Power transmission components should be totally
enclosed.
-
The work area should be neat with non-slip floor
preparation.
