At present, there are many types of hydraulic cnc press brake machine for sheet metal processing, which can be divided into mechanical (servo motor) and hydraulic type according to the rotation mode. According to the control system, it can be divided into simple manual bending machine, ordinary domestic digital positioning bending machine, process control digital full-function CNC bending machine. According to the action part, it can be divided into 4-axis, 8-axis, 12-axis and other bending machines.
Today,Maanshan Durmapress Machinery Techology Co.,Ltd talks about the use of different bending machines:
1. Before using thepress brake cnc, check whether the power is on, whether the air pressure is sufficient, whether the hydraulic pressure is sufficient, whether the machine is clean, and there are no obstacles in the slideway. After confirmation, the subsequent procedures can be carried out.
2. Turn on the cnc press brake 2500 power switch, start the oil pump to align the origin of the shaft, D-axis, cc-axis, and Z-axis to complete the starting process.
3. After installing the mold, after selecting the mold, place the machine's gear switch in the cut position, and after installing the base, lower mold and upper mold, place the machine switch in the inching or single-action position. The pedal. The up switch shakes the up rocker or knob to merge the upper and lower molds and pressurize the zero point of the D axis to lock the lower mold to complete the mold assembly process.
4. Recognize the drawings, understand the bending sequence and bending dimensions, and start programming the cnc hydraulic press brake machine. There are two input methods for programming, one is angle input, and the other is depth input. We often use depth input methods. First, put the computer into the state of mind, and enter the bending size L, D value, Z value, speed, time, number and other values. Then check and confirm the program, let the computer enter the running state when there is no error, and then modify the program with the waste trial folding to adjust the angle and size to a good state. Then carry out product trial folding, and the trial product can be mass-produced after inspection.
5. If you want to increase the bending speed during the bending process, the gear switch can be operated in a single or linked state, but for the sake of safety-generally only single action is sufficient. When bending long workpieces, the middle angle is often very large. You can adjust the CC axis to change the middle angle to be consistent with the left and right angles. In the bending process, you should also pay attention to the central bending principle, which is an important prerequisite to ensure the accuracy of the bending process. It is not allowed to bend at one end of the hydraulic cnc press brake machine. This is not only bad, but also damages the machine.
6. It is not allowed to turn off the power supply during a short break, just turn off the oil pump, so as to save electricity bills, so as to avoid re-work on the origin when going to work, save time and increase utilization.
7. If you need to stop the machine after finishing the product or after get off work, first put the lower mold to the low position, then turn off the oil pump, and then turn off the power supply. If the batch of products has been completed, you must also remove the mold, put it back on the mold rack and return to operation panel.
8. It is strictly forbidden to operate the cnc hydraulic press brake machine in violation of regulations, so as to avoid unnecessary injury to the person and equipment mold. Always pay attention to the cleaning and maintenance of the machine, and develop a good habit of caring for the equipment and molds.
