Compared with the roller feeder and the NC servo feeder, the pneumatic feeder has higher requirements for operation and
maintenance.
If the operation is improper or not regularly maintained, the
occurrence of the fault is inevitable. The pneumatic feeder fails
to have two kinds of unstable feeding and material deviation. The
following explains the troubleshooting method.
The solution of the pneumatic feeder feeder is unstable:
1. The problem of the mold itself causes the feeding to be
unstable. Solution: Manually check whether the mold has resistance
when feeding, if necessary, re-mold.
2. The air pressure outside the pneumatic feeder is unstable,
resulting in unstable feeding. Solution: Check the external air
supply to ensure the air pressure is stable.
3. the pneumatic feeder seal damage caused by the feed is not
allowed. Solution: The sealing ring is one of the wearing parts of
the pneumatic feeder. If there is no lubricating oil in the
three-way solenoid valve of the pneumatic feeder, the sealing ring
is easily damaged and the feeding is not accurate. At this time,
only the replacement can be solved.
4. The step adjustment screw of the pneumatic feeder is not locked. After loosening, the feeding is unstable, and the
targeted locking can be solved.
5. The speed adjustment of the pneumatic feeder is not adjusted
well. Solution: Re-adjust the speed-adjusting screw so that the
speed of the feeder's moving slider is the same as that of the
punch.
6. The setting time of the R type solenoid valve of the pneumatic
feeder is incorrect. At present, the pneumatic feeders are
basically equipped with an E-type solenoid valve for feeding and an
R-type solenoid valve for relaxation.
When the mold is actually used after replacement, the operator
often only changes the height of the intuitive feeder, but ignores
the different stamping processes of different molds, and the
relaxation time is also different, so the relaxation time must be
re-adjusted after the mold change.
