2 the rotating cam limit switch of the stamping equipment needs to be adjusted. The cam
SEGMENT 1 ####.## mm SEGMENT 6 ####.## mm switch of the stamping equipment is used to control the feeding start of the feeder, the
end of the feeding, the releasing of the rollers, and the pressing of the rollers.

2. When adjusting the cam switch, please make sure the stamping press is operated in
“Inch Operation” mode.
SEGMENT 3 ####.## mm SEGMENT 8 ####.## mm
3. Improper adjustment of the cam switch of the press equipment or damage to the cam
switch may cause the contact of the cam switch to jump or the signal to break off. This

will cause the feeder to operate abnormally and should be adjusted or replaced.

SEGMENT 5 ####.## mm SEGMENT 10 ####.## mm 4. For the stamping press that use an electronic cam, please set the contact closure to
“ON”, and the contact opening to “OFF”. The “ON/OFF” setting may be reversed
depending on different electrical circuit.

ALARM 1. If the feeding is continued when the mold is closed, the mold may be damaged, the
product may be scrapped, and the material may be stuck. To prevent this from
happening, there is a feeding stop signal.

2. If the signal is received but the feeding did not end, the stamping equipment will stop.

 MAINTENANCE
2. The position of the cam switch should be within the following range: From the position
where the pilot pin enters into guide hole to the position where the stamping device
reaches the bottom dead center.

3. The actual opening and closing time of the feeder rolls will be delayed a little bit
compared to the release signal time. So when the speed of stamping machine is fast,
please set the signal position slightly beforehand. DAILY CHECKLIST

equipment stop completely, the angle of the mold sliding will be different due to different
conditions such as pressing pressure, molds weight or braking effect.

As for progressive dies, the dies may be damaged if press is applied without the material
being completely delivered.

Therefore, it will need to estimate the braking angle, setting the cam switch in safety range
that can stop the press machine.
