7.3 6 X 6 NINETY DEGREE NOTCHER
The 6 x 6 ninety degree notcher is a component tool designed to cut 90 degree Vee notches in angle and
flat stock. It has a maximum capacity of 5/16 of an inch (8mm) thickness mild steel.
7.3A 6 X 6 NINETY DEGREE NOTCHER INSTALLATION
SEE FIGURE 16 ON THE FOLLOWING PAGE.
The 6 x 6 ninety degree notcher can be mounted either under the upper arm on the tool table or in the
punch station.
When the notcher is mounted on the tool table, the selector switch must be in the SHEAR position.
When the notcher is in the punch station, the selector switch must be in the PUNCH position.
⌦
CAUTION: IN EITHER STATION, CARE MUST BE TAKEN TO SET THE UPPER AND
LOWER STROKE CONTROLS ON THE MACHINE. FAILURE TO SET THE STROKE
CONTROLS WILL RESULT IN DAMAGE TO THE TOOL AND POSSIBLE INJURY TO THE
OPERATOR.
The upper stroke should be set so that the pusher assembly is held in place by the spring tension of the
tool. The lower stroke must be set so that the upper blade just passes the lower blades at the point of the
vee by no more than 1/16 of an inch (1.5mm).
To install the notcher under the upper arm, the tool should be mounted as close to the frame as possible
and anchored with the bolts (A) provided. The pusher (B) and beam block (C) should be installed per the
dimensions in FIGURE 16.
To mount the notcher in the punch station, remove the die holder and stripper. Mount the notcher, using
the heavy washer and bolt (D) provided. SEE FIGURE 16. Line the pusher (E) up to the punch ram and
tighten the mounting bolts (F). After the notcher is mounted, install the neo-prene slug pad.
7.3B 6 X 6 NINETY DEGREE NOTCHER OPERATION
Lubricate the blades before starting and every 10 to 15 cuts, thereafter. Lubricate the pusher bars (B &
C) every two hours of operation. Do not attempt to shear material thicker than 5/16 OF AN INCH (8mm)
and never side load the notcher. The slug must be removed after every cut. Remove the slug with a
magnetic probe or tongs.
DO NOT REMOVE THE SLUGS BY HAND.
ALWAYS REMOVE THE NOTCHER WHEN IT IS NOT IN USE.
