There are errors in the bending machine processing. How to adjust?
When the bending machine is working, each component includes a synchronous system, a slider part, a material blocking mechanism and a table part. The synchronous system here is composed of a torsion shaft, a swing arm, a joint bearing and the like, and the overall structure is simple and performance. Stable and reliable, high synchronization accuracy. Mainly by the wire to energize the coil, after the energization, the gravitational force is generated on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base, thereby meeting the requirements of various workpieces.
When using the bending machine to work, it is very likely that some usage errors will occur. At this time, it is necessary to pay attention to it. If the bending machine has a problem, it should be checked. The first step of the inspection is whether the mold used in the bending machine is worn or damaged. If this phenomenon causes an error, a mold can be replaced.
In the process of inspecting the bending machine, if there is no development of damage, check the parallelism between the slider and the table. If the requirements for use are not met, you can adjust according to the relevant standards to make 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 that the hydraulic system in the machine does not ensure that the pressure oil evenly enters the left and right cylinders. , then you need to adjust.
At this time, adjust the working mode of the press brake to the “jog adjustment” state, then remove the mold in the machine tool, or some other accessories, so that the slider stays on the mechanical stop, and then the pressure The table is adjusted to the required pressure value.
The specific method is to compress the meter head of the bending machine by 3-4 mm, step on the pedal to let the system boost, and check the dial indicator hour hand when the bending machine system is boosting or the system is discharging. In the case of offset, the operation can be stopped if the specified value is reached. Of course, in addition to the above methods, it is important to maintain the bending machine to maximize its use.
