Tooling Set Up and Alignment
PierceForm Installation Heads may be mounted in the die by either of
two methods: Direct Layout or Die Layout.
Direct Layout Method
- Install die button retainer by direct layout or with
template.
- Invert die set (so die button retainer is on top).
- Set assembled alignment tool in Head position.
- Lower die shoe (with retainer) so alignment insert enters
retainer. Alignment insert and retainer must be equivalent
sizes.
- Transfer alignment tool mounting holes to die (with punch).
- Repeat steps above for all Heads in die by transferring
complete alignment tool to each Head location.
- Drill and tap mounting holes for screws.
- Loosely mount alignment plates in each Head location.
- Replace mating die shoe.
- Attach alignment plate in first Head position.
- Lower die shoe (with retainer) so alignment insert enters
retainer.
- Tighten alignment plate screws through access holes, then
remove insert.
- Repeat steps above for each Head in die.
- Remove mating die shoe; transfer dowel holes using alignment
plates as drill fixtures. Drill as required for reaming.
- Ream for press fit for dowel pins.
- Locate and machine clearance holes for shank and spring.
- Install Head in each Head location. Follow plate die
tryout procedures; follow Multifastener ram setting procedures
in this manual.
Die Layout Method
- Install die button retainer by direct layout or with
template.
- Loosely mount alignment plates in each Head location by die
layout procedure.
Attach alignment insert to alignment plate in first Head
position.
- Lower die shoe (with retainer) and align tool so alignment
insert properly enters retainer.
- Tighten alignment plate screws through access holes, then
remove alignment insert.
- Remove mating die shoe; transfer dowel holes using alignment
plates as drill fixtures. Drill as required for reaming.
- Ream for press fit for dowel pins.
- Repeat steps above for each Head in die.
- Locate and machine clearance holes for shank and spring.
- Install Head in each Head location. Follow plate die
tryout procedures; follow Multifastener ram setting procedures
in this manual.
The Multifastener Registry Marker is designed to provide
immediate visual determination of proper or improper ram setting.
"Good" and "Not Good" Registry Marker
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 or Nut (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 76.07mm
(2.995")(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.)
