Application of CNC system on CNC Bending Machine

CNC Bending Machine is a general-purpose machine for sheet metal bending, which can bend various types of workpieces as required. When equipped with corresponding equipment, processes such as pipe bending, punching, bending and stretching can also be completed. When bending sheets of different thicknesses and different materials, users only need to select different molds and check the sheet bending force table, calculate the required bending force, and adjust to the corresponding working oil pressure to work. At present, the bending machines provided by various manufacturers are divided into two categories: up-moving and down-moving according to the movement of the slider.

The numerical control device is a kind of numerical control equipment dedicated to the CNC Bending Machine, which can provide a complete and economical solution for the torsion axis bending machine. It has the characteristics of high performance, compact structure, easy operation, and high reliability, which are embodied in the following Aspect: Servo motor is used for high-precision positioning control of the back gauge and cylinder stroke position; it has one-way or two-way positioning function, which can effectively eliminate the screw transmission gap and improve positioning accuracy; the back gauge and slider position have automatic search and power-off Automatically memorize the value function of the actual position afterwards. With single-step and multi-step programming functions, automatic operation can be realized after setting; with retreat and escape function to avoid interference between the backgauge device and the bending workpiece; quick configuration of the slide block, work advance, and unloading , The solenoid valve in the return state is energized; the system has intuitive hardware diagnostic monitoring, which makes the machine tool more convenient to maintain and use; simple parameter programming and complete detection, the system detects the input data and prompts correction ;Provide the function of simulated upper limit, after processing, there is no need to return to the upper limit, which improves the processing efficiency.

CNC Bending Machine has complete diagnostic functions, concise and clear alarms and monitoring, and one-click restoration of factory settings, etc., which effectively reduces the service cost in the later stage of system operation and can meet the requirements for rapid troubleshooting. Trial bending through the “error tracking” method can quickly adjust the operating parameters of the machine tool and the mold in place, usually after the thickness and strength of the sheet are changed, the depth position of the upper mold folded into the lower mold on the Y axis and the pre-convex value of the adjustable table It needs to be adjusted, which can provide protection for the operator very close to the workpiece, and can easily meet the safety protection needs when processing parts of different shapes.
