4.10 Wire Processing Setup and Feed Cam Orientation
Setup for Wire Processing
There are several adjustments that may be needed if the applicator is to be used in a fully automatic wire processor.
Molex applicators are typically set up at the factory for benchtop application. The following information pertains to
applicator use in automatic wire processors only:
The feed cam position may need to be flipped to post-feed timing.
The terminal forward feed position should be verified on the wire processor in case the change in press speed
affects the crimp symmetry.
It is a common practice to remove the scrap shield and wire stop.
o
Rather than removing these parts, Molex recommends making adjustments to these parts if they are
causing interference. The wire stop also acts as a terminal stripper, helping to remove the crimped terminal
from the punch. In most cases, adjusting the vertical height will provide the clearance needed in wire
processing.
o
If the wire stop must be removed from the workspace, then it can be flipped around and mounted backward
in its location to prevent its loss.
Many of the FA2 applicators have a cut-off retainer where the cutting insert can be removed to allow the wire
processor to chop the scrap carrier strip.
At the completion of a job, it is recommended that applicators are checked for lubrication and potential tooling
wear to expedite future installation.
Feed Cam Orientation
1.
The terminal feed stroke is driven by a cam mounted to the applicator ram. The cam is compatible with press strokes
between 28.6-41.3mm (1 1/8-1 5/8”).
Note:
Using the applicator in a press with a stroke outside of this range may result in insufficient feed stroke
or incorrect feed timing.
2.
Determine what feed timing is required. See Figure 4.10.1.
Note:
The applicator is shipped with the cam mounted for pre-feed timing.
Caution: Always disconnect press
power before installing or removing
tooling.
Caution: DO NOT
operate the
applicator without guards in place.
3.
Disconnect power to the press. Remove
machine guards if necessary.
4.
Remove the terminals from the
applicator, and remove the applicator
from the press.
5.
Push the feed pawl slide toward the ram so the feed pivot lever is vertical, and lift the ram to remove it from the
applicator. See Figure 4.10.2.
6.
Use a 3mm hex wrench to remove the two M4 screws holding the cam to the ram. See Figure 4.10.3.
