Three troubleshooting cases of Heidelberg Suba 102v

1 When printing innovative polymer solutions of different quality and several key components of LED lighting have been developed, in order to make the paper neat at the paper receiving position, it is necessary to often adjust the open tooth plate of the paper receiving tooth row. We summarize several common faults and other accessories of the tensile testing machine. Due to the frequent adjustment of the tooth opening and the collision between the tooth opening plate and the tooth opening ball, the tooth opening plate φ The 18mm hole is worn, and the long hole supporting the die plate is also worn, resulting in the adjustment failure of the die plate and the paper is not easy to collect

to eliminate the fault, we remove the die plate and φ 18mm hole enlarged to φ 22mm, turn another piece, and the inner hole is φ 18mm, outer circle is φ What should we pay attention to when using the 22mm shaft universal experimental machine? The sleeve is embedded in the worn hole of the die plate and fixed with slotted screws. The worn long hole shall be repaired and leveled by repair welding. After reinstallation, the use effect is good

2. To adjust the height of the paper suction nozzle on Feida, connect a steel wire to a fixed support, and rotate the steel wire through the knob to make the suction nozzle move up and down. Due to the tight suction nozzle and frequent adjustment, the steel wire at the head of the suction nozzle is often broken. Because this steel wire is different from ordinary steel wire, we can't find a substitute, so we trimmed the steel wire. Although the trimmed steel wire is a little shorter, it can be made up by making a new steel wire clamp. Generally, 1/10000 gram of steel wire is often used to put it into one side of the clamp head, press it firmly with a press, and the other end is connected to the suction nozzle to lock it in place. Then adjust the tightness of the suction nozzle, and the free adjustment of the suction nozzle is restored

3. The clutch pressure of Heidelberg offset press is realized by the push of air valve. The air valve is controlled by the closing control signal of the solenoid valve, so as to realize the clutch pressure of the drum. In printing, we have encountered late clutch pressing action, resulting in the transfer of the imprint to the imprint cylinder, or only half of the paper printed, resulting in waste products. After inspection, no problem was found with the air valve and the control signal of the solenoid valve. Later, the solenoid valve was simply turned on, and it was found that there was oil in the solenoid valve coil and valve core. After the oil was cleaned, the fault also disappeared
