Tooling Set-Up and Alignment Procedures
The Multifastener
registry marker is designed to provide immediate visual
determination of proper or improper ram setting.
Function
-
The registry
marker has a raised circle with the letters “N ” and “G ”
located within, raised to different levels (see Fig.2).
-
At the bottom
of the die stroke, if a circle and a “G ” are stamped in your
metal panel, the die is set properly (see Fig.1).
-
If a circle and
“NG ” appears, the hit is too hard (see Fig.1).
-
If no mark
appears, the hit is too light (see Fig.1).
Location in the Die
The registry marker
is mounted in the same die shoe as the installation head and is
positioned over the part panel that is to receive the PierceForm ®
Stud (see Fig.3).The registry marker should be located as close to
the head as possible.
Setting
The proper shut
height of the “Good ” registry marker is 76.07 mm (see Fig 3.
Shut height dimension does not include retainer plate thickness.
Mounting in the
Die
The registry marker
incorporates a heavy-duty lock feature to facilitate mounting in the
die. (Ball lock retainer must be provided by customer.)

Visual Inspection of the Stud Installation
Proper ram setting can be achieved and continuously checked by
visually inspecting the PierceForm stud flange as installed, using
the following guide.
| CS Stud |
Case 1: Proper Ram Setting
The post side of the stud barrel is flush to 0.20mm below
the panel |
Case 2: Too Light
The post side of the stud barrel is above flush with the
panel. |

PierceForm Stud Head Set-Up Adjustments
During die tryout of the PierceForm Stud Installation head (and
during normal operation) certain conditions may occur which may be
easily corrected.

No stud is
deposited in Panel (Causes)
- No studs in head
(check stud supply for obstruction in feed system, chuting).
- Head improperly
assembled (check for proper assembly).
- Head failing to
open fully.
- Improper
shut-height setting (check ram setting -nose contacts base).
- Obstruction in chuting or chute attaching block (shut off stud flow and clear
blockage at feeder).
- Stud jammed in
head (remove chute attaching block and clear jammed stud from head.
Head Fails to Open Fully (Causes)
- Check main
compression spring.
- Check for
obstruction in air port.
Air Pressure
- A constant air
supply of 40-60 PSIG is required at air port. This air supply will
insure that the head is in the proper position before stud
installation.
Stud in Head - Press Will Not Cycle
Recommended Alignment Method
-
Install die
button retainer on lower die shoe by direct layout or with
template. Insert alignment die button in retainer.
-
Locate
installation head mounting screws in upper die shoe by die
layout.
-
Loosely mount
base, back-up plate and plunger with screws.
-
Lower upper die
shoe so that the plunger properly enters alignment die button.
-
Tighten head
mounting screws.
-
Repeat steps
for each head in die.
-
Transfer dowel
holes into upper die shoe. Drill holes and ream for press fit
dowel pins.
-
Locate and
machine clearance holes for shank and spring in upper die shoe.
-
Install head in
each head location. Follow plant die tryout procedures; follow
ram setting procedures in this manual.
