SINGLE-CRANK PRECISION PRESS from China fault and troubleshooting method

In the operation of SINGLE-CRANK PRECISION PRESS from China, there will inevitably be some glitches. Do you know how to troubleshoot and troubleshoot it? Let’s take a look at it briefly below!

First, the disengagement after the upper and lower clamps are closed: When the upper and lower clamps are closed and the slider stops moving, please follow the following methods to disengage and use the clutch as the method of disengagement.
1. Whether the crankshaft direction is before or after the bottom dead center must be determined.
2. The air pressure of the clutch is adjusted to 4--5, 5kg/cm2.
3. After passing the bottom dead center, the motor can rotate in the original forward direction. If before the bottom dead center, the connecting sides of the motor must be reversed in the opposite direction to make the motor reverse.
4. Start the motor to drive the pulley to idle, and then reverse at full speed.
5. Switch the operation switch to jog, then press and release the operation button switch. After repeating the operation a few times, the slider will rise to the direction of the starting point.
Second, the method of SINGLE-CRANK PRECISION PRESS from China to disengage the overload safety device (limited oil pressure overload safety device):
1. Switch the check valve in the pipeline of the overload device so that the oil pump cannot run.
2. Pull out the bolts of the oil circuit of the overload safety protection device in front of the slider, let the oil flow out, reduce the internal pressure, and then fix the bolts in place.
3. Start the motor to drive the pulley to idle, and then run at full speed.
4. Switch the operation switch to jog, then press and release the operation button switch. If the clutch fails, switch the overload switch to the reset position, then repeatedly press and release the push button switch to raise the slider to the starting position.
5. After the upper and lower molds are engaged and disengaged, open the check valve switch of the pipeline in the overload device, and the reset operation sequence is the same as that of the overload safety device, and then the normal operation can be carried out.
The above is the introduction to the faults and troubleshooting methods of SINGLE-CRANK PRECISION PRESS from China, I hope you can learn more.
