Setting Up the Press Brake
Do not bend any material
larger than 30” (40”) 20-gauge mild steel.
Failure to comply may cause serious injury
and/or damage to the machine.
To set up for bending:
1. Place a strip of wood on the bottom die the
full length of the die.
2. Close the brake until the wood contacts the
upper dies.
3. Loosen the socket head cap screws (Figure
4) using a 6mm hex key.
4. Select upper die(s) (Figure 4) for the desired
job and remove the others by sliding them
out the left end.
5. Move the operating handle until the wood
pushes up the dies so that they seat
uniformly in the upper beam.
6. Securely re-tighten all screws (Figure 4),
then release and remove the wood strip.
7. If making repeated bends or using a long
workpiece, position the guide rods and plate
for brake operation, as shown in Figure 5.
8. Scribe a line on the workpiece for the bend
location. (Be sure to accommodate bend
allowance based upon thickness of the
material. This can be done either through
trial and error, or by consulting a machinist’s
handbook.)
9. Rest the workpiece on the v-block (lower
die) so that the scribed line is aligned with
the tips of the upper die(s).
10. Hold the workpiece steady and use the
operating handle to make the bend.
To adjust the brake beam to make 90
°°°°
bends
at the bottom of the stroke:
1. Slightly loosen locking screws (D, Figure 6)
using an 8mm hex key.
2. Turn brake beam adjusting screws (E,
Figure 6) using a 19mm wrench, until test
bends reflect a 90
°
bend at both ends of the
brake.
3. Re-tighten locking screws (D, Figure 6).
For special repetitive bends, the brake beam
may be adjusted to over-bend the desired angle
since the metal will have some degree of “spring
back”.
