The Working Principle and Using Method of CNC Press Brake

The working principle of CNC press brake


The upper and lower molds are respectively fixed on the upper and lower worktables of the folding machine, the opposite sides of the worktable are driven by hydraulic transmission, and the shapes of the upper and lower molds are combined to realize the bending and forming of the plate.


How to use 3D CNC press brake


1. First, turn on the power, turn on the switch on the control panel, and then start the oil pump


2. Turn on


1) Follow the operation steps to operate the machine tool correctly;


2) When the machine tool of the CNC press brake is in operation, if an abnormal situation occurs, immediately stop the inspection, and refer to the relevant troubleshooting methods in the "Training Manual" to troubleshoot;


3) If an alarm occurs and the machine of the CNC press brake stops when it is running, it should be treated differently, and it should not be operated blindly to avoid damage to the machine;.


4) For the newly executed program, the first workpiece must be checked according to the drawings to avoid batch errors;


5) If abnormal conditions are found in the mold during the bending process, stop the machine for inspection in time;


6) Frequently check whether the actual position of the X-axis is consistent with the detected value, and adjust in time if there is a deviation.


3. Stroke adjustment, you must pay attention to adjusting the stroke when using it, and be sure to test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise it will cause damage to the mould machine. The adjustment of the stroke also has electric quick adjustment.


4. For the selection of bending notches of the CNC press brake, a notch with a width of 8 times the thickness of the plate is generally selected. If you bend a 4mm sheet, you need to choose a slot of about 32.


5. Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, the method is the same as the shearing machine.


6. Step on the foot switch to start bending. The mold of the 3D CNC press brake is different from the shearing machine. It can be released at any time, release the foot to stop, and continue to go down when stepping on.
