1. Press the lever on the air valve or pump the handle to apply load to the piece part. Applied
pressure is read on the pressure gauge (13).
2. When the work is done, release the lever on the air valve, or stop pumping on the handle.
3. Slowly and carefully remove the load from the piece part by turning the release valve (35)
counterclockwise (ccw) in small increments until the ram backs away from the piece part.
4. Once the ram has fully retracted, remove the piece part from the bed frame.
5. Disconnect the air valve from the air source.
UNDERSTANDING SPRINGBACK
Springback, also known as elastic recovery, is the result of the metal wanting to return to its
original shape after undergoing compression and stretch. After the bending leaf is removed from
the metal and the load is released, the piece part relaxes, forcing the bent portion of the metal to
return slightly to its original shape. The key to obtaining the correct bend angle is to over bend
the metal a little and allow it to spring back to the desired angle. All metals exhibit a certain
amount of spring back.
MATERIAL SELECTION
When selecting materials keep these instructions in mind:
•
Material must be clean and dry. (without oil)
•
Material should have a smooth surface so it processes easily.
•
Dimensional properties of material must be consistent and not exceed the machine capacity
values.
•
Chemical structure of material must be consistent.
•
Buy certificated steel from the same vendor when possible.
WARNING:
Failure to center the piece part on the blocks and the ram to
the piece part may cause serious injury.
Never compress springs or objects that when compressed, could shatter, or explode
out of the press causing serious injury.
CAUTION:
It must be determined by the customer that materials being
processed through the machine are NOT potentially hazardous to operator or
personnel working nearby.
