The Servo Feeder of the High-speed Punch Machine's Minor Troubles--An Explanation of SAMHOOR

When the servo feeder is used in a high-speed punch, if the operation is not good, some small faults will often occur. So, what are the general failures of high-speed punching presses with servo feeders?

There are generally the following five types of failures of the servo feeder:

　　 1. The feed error has a fixed direction. There are several reasons for this problem: insufficient feed roller pressure; feed length is too long or too short; there are burrs or foreign objects in the mold. In order to solve different problems, is it appropriate to increase the pressure, coil width and mold guide plate? Or whether the fixture and the CNC feeder are in a straight line, check the blanking plate and stripping plate.

2. Sudden errors during feeding are determined by the error of the CNC feeder during the seasoning, whether the leveling machine matches the servo feeder or the distance between the leveling machine and the CNC feeder, the height of the material arc, and whether the number of turns of the punch is appropriate, and Caused by the large transmission gap between the roller and the servo motor. At this time, just tighten the belt of the pulley.

　　3. The feed error and inaccurate direction are generally caused by metal or other foreign matter entering the feed roller or gear, and the start and release of the feed interfere with the action sequence of the punch. When the material is fed into the feeder, the rollers will slip. To understand the reason for the failure, you only need to adjust for different problems.

　　4. The feeding amount is twice or more than usual, which often happens. Immediately check whether there is noise interference at the wiring terminals of the micro switch and the servo feeder. If there is noise interference, replace the wire between the micro switch and the junction box. And use metal mesh to isolate the wire.

　　5. Sometimes the roller release is not smooth, it is caused by the abnormal SW signal of the micro switch of the press release cam, the deviation of the feeding direction, and the abnormal operation of the air compressor. At this time, you only need to adjust the air compressor or replace the solenoid valve, cylinder, pipeline, etc., and check whether the wire is off or replace the micro switch or relay in the electrical box.
