During the use of the three-in-one feeder, the power source used for relaxation is air pressure, and it is generally used in conjunction with the punching machine. It is inevitable that vibration will occur, and the three-in-one positioning screw is often loosened due to vibration. However, the method of flattening the feeding accuracy is affected. Therefore, the current method is to directly process the countersunk hole on the side plate at the end of the positioning shaft and the distance between the fixed side plates, or without the positioning axis. This method is not conducive to adjusting the positioning axis. To eliminate the error.
Fault one, fault analysis: coil snake
Reason analysis: 1. The width of the material roll and the position of the material stop wheel are improper; 2. The pressure of the roller is uneven; 3. The slippage is stuck; 4. The pressure of the roller is too large.
Exclusion method: 1, re-adjustment; 2, re-adjustment; 3, check whether the mold guide groove is in line with the NC, whether there is scrap in the mold, whether the material has burrs; 4, readjust.
Fault two: sudden error during feeding
Reason analysis: 1. Whether the adjustment of the material by the NC feeder is suitable; 2. The transmission gap between the roller and the servo motor is too large; 3. The unevenness of the coil material.
Exclusion method: 1. Whether the speed of the leveling machine NC is matched, or whether the intermediate distance between the leveling and the NC, the material arc height and the punching speed are appropriate; 2. The belt is tightened; 3. Check whether the length, width and thickness of the coil material are standard.
Fault three: the feeding error has a fixed direction
Reason analysis: 1. The feed wheel pressure is insufficient; 2. The feed length is too long; 3. The feed is insufficient; 4. There is hair or material in the mold.
Exclusion method: 1. Increase the pressure; 2. Pull the material due to poor removal of the upper mold; 3. Check whether the width of the coil and the position of the mold guide plate are appropriate, or whether the mold and the NC are in line; 4. Check the stopper plate and Whether the stripper has burrs and foreign objects.
