During the actual use of the press feed line, due to various factors such as improper operation, incorrect debugging, and machine wear, it is inevitable that there will be failures. Once such failures occur, they need to be solved in time to avoid affecting the actual stamping production.

Fault 1: The plate flattened by the three-in-one feeder is skewed left and right
Reason: The press punch machine and the coil leveling machine are not on the same line, and the leveling roller bearing is worn
Remedy: Readjust the position of the machine and update the leveling roller bearings.

Fault 2: The flattened sheet is warped upwards
Reason: Too much pressure under leveling
Remedy: Increase the number of the digital display on the leveling machine, that is, the upper leveling seat rises up and reduces the amount of depression.

Fault 3: There are transverse indentations on the surface of the flattened sheet
Reason: Too much pressure under leveling
Remedy: Increase the number of the digital display on the leveling machine, that is, the upper leveling seat rises up and reduces the amount of depression.

Fault 4: The plate flattened by the press feed line deviates downward
Reason: The amount of pressure under leveling is too small
Remedy: Decrease the number of the digital display on the leveling machine, that is, the upper leveling seat is lowered, and the pressing amount is increased.

Fault 5: There are vertical indentations on the surface of the flattened sheet
Reason: The board is dirty when feeding, and there are dirty foreign objects on the leveling roller
Remedy: Use a long cloth dampened with oil to clean the leveling rollers.

Fault 6: There are regular indentations in the middle of the flattened plate
Reason: The hard chrome layer on the surface of the upper and lower leveling rollers is peeling off
Remedy: replace the leveling roller.

The above are the common faults and solutions of the press feed line organized by Henli. I hope the above methods will be helpful to everyone.
