This article will introduce how to set up the CNC press brake machine when using it for the first time, the steps to operate the CNC press brake at work, and the key points of maintaining the CNC press brake, helping you to fully understand how to operate the CNC press brake.
How to set up the CNC press brake machine when using it for the first time
Step 1: Add hydraulic oil
Add hydraulic oil and connect the power cord to the CNC press brake machine. Fill the oil tank with anti-wear hydraulic oil from this port. Connect the CNC press brake machine to the power source and connect the pedal switch to the machine.
Step 2: Test power supply
Turn on the power switch of the CNC press brake machine, turn right to turn on the system switch, and start the oil pump. Check the main motor rotation direction, if it rotates clockwise it is correct. If it rotates counterclockwise, turn off the main power supply and swap the two wire connections.
Step 3: Setup programming
Operate the system of CNC press brake machine. Select graphic programming, create a new task, select the upper mold and lower mold, insert the layout sequence, enter the length and plate thickness in order according to the product, and set the setback distance.
Step 4: Conduct operational testing
Place and fix the metal plate, step on the pedal, and bend the metal plate.
Step 5: Make adjustments and retest
Measure the bending angle of the metal plate. If an error is found, enter the actual measured angle to calibrate the parameters in the system. After the second bend, the metal plate is measured again using an angle ruler to determine the accuracy of the parameters.
Operating steps for CNC press brake
The specific operating steps and precautions for the CNC press brake are as follows:
Step One: Operators should wear labor protection equipment, such as safety glasses and gloves. The CNC press brake machine should be operated in accordance with operating procedures and other regulations.
Step 1: Check CNC press brake machine
Ensure that the fasteners in all parts of the equipment are not loose, the operating buttons, motors, and circuits are faultless, the safety protection devices are complete and effective, and the moving parts are well lubricated. Check the overlap and solidity of the upper and lower molds to ensure that the positioning device can work normally. In addition, let the CNC press brake run without load for 1-2 minutes to ensure normal operation.
This step ensures the stability, reliability of the equipment and the safety of the operators, and lays the foundation for subsequent bending operations.
Step 2: Programming bending specifications
Use the CNC system to program the bending specifications according to the size and shape of the workpiece. Simulation operations are performed to verify the accuracy of the program before actual execution.
Programming is a key aspect of using a CNC press brake, allowing for complex and precise bending operations, while simulation operations ensure that potential issues, such as bending angles or bending pressures that need to be adjusted, are identified and resolved before the actual sheet metal is machined.
Step 3: Setting parameters
Adjust equipment parameters according to the workpiece material, thickness, and bending angle, including bending pressure, speed, stroke, etc.
Precise parameter settings are critical to ensure the quality and efficiency of bending operations and prevent potential workpiece damage or equipment failure.
Step 4: Fixed workpiece
Place the workpiece to be bent at the designated position of the CNC press brake, and ensure that it is firmly fixed to avoid displacement or tilt.
For large or heavy workpieces, specialized clamps or lifting equipment are required for handling and securing. At the same time, attention needs to be paid to the placement position and direction of the workpiece to ensure that it meets the programming requirements.
Step 5: Perform bending work
Press the start button to perform the bending operation and closely monitor the operating status of the equipment during operation to detect and handle abnormal situations in a timely manner.
By observing the operating status indicator light of the equipment, listening to the sound of the equipment, and observing the bending of the workpiece, problems that may arise during the operation of the equipment can be discovered in time. Once an abnormality is discovered, the emergency stop button needs to be pressed immediately and measures taken to deal with it.
When the CNC press brake is working, a dedicated person should provide unified command, and personnel in all parts should cooperate closely and follow the instructions.
Step 6: Check finished product quality
After the equipment completes the bending operation, check the quality of the finished product to ensure that it meets the requirements. Workpieces with quality problems will be reworked or scrapped. At the same time, remember to clean the work area and the press brake to improve work efficiency and safety.
Maintenance for CNC press brake machine
First of all, the equipment needs to be cleaned before and after using the CNC press brake, not only the workbench area, but also the control screen to prevent the touch screen effect from being unsatisfactory due to oil stains on it during settings.
Secondly, to lubricate the slider and other movable parts, be sure to use special lubrication tools to avoid using ordinary lubricating oil, which may cause impurities to stick to the equipment.
In addition, a link that cannot be ignored in the maintenance of CNC press brake machine is the inspection of the equipment, which includes the electronic and mechanical parts of the machine. This allows you to maintain machine performance while reducing maintenance costs and safety hazards.
Precautions when using hydraulic oil
Hydraulic pressure is the power source of hydraulic CNC press brake machine. Next we understand what to pay attention to when using hydraulic oil.
It is best to preheat the bending machine before use to allow the hydraulic oil to flow. Low temperature will cause the water in the hydraulic oil to solidify. The solidified water will adhere to the parts of the hydraulic valve and the surface of the oil filter , which may cause the hydraulic valve to become stuck.
The best ideal temperature of hydraulic oil is 30 degrees to 60 degrees. If the temperature in your place is low, it is best to lower the grade a little and use No. 32 anti- wear hydraulic oil.
