The pneumatic feeder is one of the earliest and lowest-priced models among the three mainstream feeders on the market. It is precisely because of its low price that it can automate the press at the least cost. Therefore, there is still a stamping industry. Not a small market.
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 feed stably. The materials are deviated from the two types. Long Gengyi Machinery is a professional feeder manufacturer, and then the treatment of the two major faults of the pneumatic feeder is explained in detail.
First, the pneumatic feeder is unstable solution:
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 feeder basically has an E-type solenoid valve for feeding and an R-type solenoid valve for relaxation. When the mold is actually used, the operator often only changes the intuitive height of the feeder, but ignores the difference. The mold stamping process is different, and the relaxation time is also different, so the relaxation time must be re-adjusted after the mold change.
Second, the solution to the deviation of the pneumatic feeder material:
1. The mold is not properly installed in place, causing the material to run off when feeding. When installing a small mold on a large punching machine, the mold installation is often not in place. At this time, the center line of the mold is not on the same line as the center line of the feeder, and the deviation is inevitable. At this time, the mold mounting position is re-adjusted. Can be solved.
2. The position of the pneumatic feeder's retaining wheel is not properly adjusted, which causes the material to be deflected during feeding. Re-adjusting the position and width of the retaining wheel can be solved.
3. When the material is not squared during the feeding, the material is deflected into the feeder, and the material is retracted after retracting.
4. The wear of the O-ring seal causes the air leakage of the exhaust hole to cause the pneumatic feeder to not work normally. At this time, the O-ring can be replaced to solve the problem.
5. The looseness of the pneumatic feeder is incorrect, which causes the material to deflect and re-adjust the relaxation time of the R-type solenoid valve of the pneumatic feeder.
