Handling of common problems of GANTRY PRESS
The most common problem with GANTRY PRESS is the appearance of scratches. Although it does not affect the normal use of the four-column press, the appearance of the problem means that some aspects need to be adjusted, such as the gap is too small, the appearance of the pressing wheel is rough, and the surface of the plate is rough. Improper color coating, the profile wheel has a zinc layer. To make corresponding adjustments, re-measure the gap until it is just right, polish the pressing wheel with a whetstone and apply oil again after smoothing. The most troublesome problem of forging machinery is running skew, because the center line is not straight, and the feeding baffle is not perpendicular to the pressing axis. The corresponding treatment method is to find the center line again, calibrate the center line, adjust the feeding baffle to see the deflection direction of the product, and then calibrate it. When the clutch does not work and is disengaged, there is a severe impact phenomenon because the tension spring of the four-column press operation key is cracked and loose, the operation key tail is cracked or the operation key is damaged. Replacing tension springs, working keys, adjusting the brakes of four-column presses and other major device problem solutions. The following briefly talks about the 4 faults and their solutions.
1. Uneven loading: There is residual gas in the system, which can be operated through the relevant content in the third item, and loosen the oil pipe joint at the lower part of the back of the cylinder.
2. The oil pump motor does not work: replace the safety wire.
3. The display screen does not appear: replace the safety wire; remove the rear cover to check whether the power cord is firmly connected
4. The display screen of GANTRY PRESS is abnormal: after the power is off, open the back cover to check whether the sensor input connector is reliable. If it is in good condition, check whether the sensor is normal.
