Cincinnati 175 CB - Set-Up and Use; Inserting Tooling

SET-UP AND USE
PRELIMINARIES - Before installing tooling in the Press
Brake
Set the machine controls:
MODE Selector -----------------------tlINCH" (Palm-
buttons only)
SPEED Selector ---------------------- MEDIUM/LOW
Top Stop Cam ----------------------- All The Way Up
Speed Change Cam -.----------------- All The Way Up
Bottom Stop ------------------------- All The Way Down
(O.ooott)
TONNAGE Control (Optional) -------- Set on minimum
tonnage
Run the ram to the bottom of the stroke and turn the
STROKE CONTROL sWitch to the "OFpft position.
Place the filler block ( die holder) on the bed and
lightly bolt it in place. In some cases a filler block
.may not be required and the lower die may be placed
directly on the bed. Deburr and lightly oil the top of
the filler block and loosen all of the filler block set
screws.
5. Loosen all of the ram die clamps and run the ram
upward so there is just enough space for the upper
die. Turn the STROKE CONTROL switch to the "'OFF
fl
position.
4. Insert lower die on the filler block leaving it extended
past the end of the bed several inches. Visually
center filler. block so lower die is aligned with the slot
in the ram nose.
2 • Be safety conscious. Always follow the safety
precautions outlined in this manual.
4. Whenever installing or removing tooling always place
the MODE selector in the "INCH" position. When in
this mode the ram can only be cycled by use of the
dual palmbuttons.
3. Select the proper tooling for the job. Make sure the
dies are in good condition.
5. Never place hands or arms between the dies.
1. Know the machine - thoroughly read this manual and
become familiar with all of the controls and how they
affect the ram motion. Run the machine and become
familiar with its "feel".

A hydraulic press brake is a very versatile bending
machine. It is capable of exerting high forces between its
bed and ram. These forces are applied and directed into
the material to be formed by the use of tooling (dies).
The type and shape of the dies are the principle factors in
establishing the shape of the part to be formed. There are
many different types and shapes of press brake dies.
Some have a very special and unique shape. However,
most dies are members of a family of tooling called Vee
Dies. See Figure 28. These dies, being the most common
and widely used, will be referred to in the following
instructions.

6. Rest the upper die on extended portion of lower die.
Make sure tongue of upper die is in the ram nose slot
and that the upper die is trapped by the lower die
and ram die slot. See Figure 29. Then slide upper
die into lengthwise position with the lower die. Slide
the set of dies into a centered position on filler block.
Tighten the filler block set screws to lock lower die.
