How to adjust CNC Press Brake after bending error

When using a CNC bending machine for work, there may be some use errors. At this time, it is necessary to pay attention to it. If there is a problem with the bending machine, it should be checked. The first step of the inspection is whether the mold used by the bending machine is worn or damaged. If this phenomenon causes errors, you can replace a mold.

During the inspection of the CNC bending machine, if there is no damage, check the parallelism of the slider and the worktable. If it cannot meet the requirements for use, you can adjust it according to the relevant standard requirements, making this Parallelism can be kept within the allowable range.

If there is still a certain error in the angle of the bending mechanism, it may not be due to the mold, or the problem of parallelism, it may be caused by the balancing mechanism in the hydraulic system of the machine tool that does not ensure that the pressure oil evenly enters the left and right cylinders , Then it needs to be adjusted.

At this time, adjust the working mode of the bending machine to the "inching adjustment" state, and then remove the mold in the machine tool, or some other accessories, so that the slider can stay on the mechanical stop, and then the pressure The meter is adjusted to the required pressure value.

The specific method is to compress the head of the dial indicator in the bending machine by 3-4 mm, and step on the foot to increase the system pressure. When the press brake system is boosted or the system is discharged, check the dial indicator hour hand In case of deviation, the operation can be stopped if the specified value is reached. Of course, in addition to the above methods, it should be emphasized that the bending machine must be well maintained so that it can maximize its advantages in use.
