How to adjust the bending error of CNC bending machine?
2021-04-25
In the use of CNC bending machine to work, it is likely that there will be some use error, this time we should pay attention to, once the bending machine has a problem to check. The first step in the inspection is whether the mold used by the bending machine is worn or damaged. If this phenomenon causes errors, a mold can be replaced.
In the process of checking the CNC bending machine, if there is no development of damage, check the parallelism of the slider and the worktable. If it cannot meet the requirements of use, it can be adjusted according to the relevant standard requirements, so that this parallelism can be maintained within the allowable range.
If there is still a certain error in the angle of the bending machine, it may not be because of the mold or the parallelism problem, it may be caused by the fact that the balance mechanism does not ensure that the pressure oil enters the left and right cylinders evenly in the hydraulic system of the machine tool, which needs to be adjusted.
At this time, adjust the working mode of the bending machine to the state of "inching adjustment", 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 adjust the pressure gauge to the required pressure value.
The specific method is to compress the head of the dial indicator in the bending machine by 3-4mm, step on the pedal to boost the system, and check the offset of the dial indicator when the bending machine system boosts or the system discharges the load. If the specified value is reached, the operation can be stopped. Of course, in addition to the above methods, it is important to emphasize that the bending machine must be maintained to maximize its use.
