During the inspection of the CNC bending machine, if there is no development of damage, check the parallelism between the slider and the worktable. If the application requirements are not satisfactory, adjust according to relevant specifications to maintain this parallelism within the agreed range.
If there are still certain errors in the viewpoint of the bending machine parts, it may not be due to mold or parallelism issues, but it may be due to the hydraulic system in the machine tool, where the balance organization does not ensure that the pressure oil evenly enters the left and right oil cylinders, requiring adjustment.
At this time, adjust the operation method of the bending machine to the “jog adjustment” state, then remove the mold or other accessories next to the machine tool, so that the slider can stay on the mechanical stopper, and then adjust the pressure gauge to the required pressure value.
The detailed method is to compress the dial gauge head of the bending machine by 3-4 millimeters, press the foot pedal to increase the pressure of the system, and check the clockwise deviation of the dial gauge when the bending machine system is increased or unloaded. If the specified value is reached, the operation can be stopped. Of course, in addition to the above methods, it is important to maintain the bending machine well to maximize its advantages.
Specific working and usage methods of CNC hydraulic sheet metal bending machine
- Firstly, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start. This way, you will hear the rolling sound of the oil pump. (At this moment, the machine is not moving)
- Travel adjustment: It is necessary to pay attention to the adjustment of the travel when using the bending machine, and make sure to test run it before bending. It is necessary to ensure that there is a gap in the thickness of the plate when the upper mold of the bending machine descends to the bottom. Otherwise, it will cause damage to the mold and machine. The adjustment of the itinerary also includes electric quick adjustment and manual fine-tuning.
- When selecting bending grooves, it is generally necessary to choose a groove with a width of 8 times the thickness of the plate. If bending a 4mm sheet metal, a groove of around 32 needs to be selected.
- The adjustment of the rear stopper generally includes electric quick adjustment and manual fine adjustment, using the same method as the shearing machine.
- Step on the foot switch to start bending. The bending machine is different from the shearing machine and can be released at any time. Release the foot switch and the bending machine will stop, and continue to descend when stepped on.
