CNC bending machines are widely used in manufacturing industries such as aerospace, automotive, shipbuilding, electrical appliances, machinery, and light industry. Therefore, proper operation and correct usage are of great importance. The following tips should be noted when using the machine:
- Operators should frequently check all connecting bolts and pipe joints to ensure they are tightened before operation.
- Key machine components such as the frame adopt a welded structure.
- When using the CNC bending machine, operators should regularly inspect the welds during operation.
- If cracks are found, stop the machine immediately. Operation can only resume after repairs are completed by technical personnel.
- Ensure the metal hydraulic bending machine is reliably grounded.
- The back gauge of CNC sheet metal bending machines is driven by a servo motor, enabling precise positioning.
- The back gauge of Dadong CNC hydraulic bending machines uses imported brand-name components and allows manual fine adjustment.
- It is necessary to regularly check the gap between the lead screw and nut. If the gap is too large, retighten the components or replace worn parts to ensure accurate positioning.
- Operators are prohibited from adjusting the back gauge fingers while standing in front of the machine.
- When using a hydraulic sheet metal bending machine, it is required to bend materials of different types, thicknesses, widths, and lengths.
- Therefore, the correct upper tool and lower die must be selected.
- When the sheet thickness changes, the opening width of the lower die needs to be reselected.
- When bending short workpieces, operators should place the sheet in the middle of the machine to avoid load imbalance.
- It is often necessary to adjust or change the opening of the lower die. In such cases, lifting rings can be used to rotate or move the lower die, so as to select the correct V-groove on the bending die of the CNC bending machine.
- Never operate the hydraulic bending machine under a bending force exceeding its rated capacity, as this may cause machine damage.
- Do not put hands or any part of the body into the die area at any time.
- Never reach through the die area from the front of the machine to adjust any components behind the plunger.
- Keep the body away from the workpiece to prevent injury caused by workpiece bending during machine operation.
- When the CNC bending machine stops working, the ram must be kept at the bottom dead center.
To ensure stable power supply, the following points must be noted during the operation of the hydraulic bending machine:
- Operators must not perform welding on the machine or connect high-power devices to it.
- The machine must not be used as a grounding conductor.
- Ensure the high-power connection points of the machine are stable and there are no high-voltage circuits.
- Hydraulic CNC bending machines should be installed in workshops free from direct sunlight.
- The optimal operating environment for hydraulic bending machines is one with low humidity, little dust, and good ventilation.
- Before using the CNC bending machine, confirm that the hydraulic system can protect the machine from overload during bending pressure application.
- Dadong CNC sheet metal bending machines all use electro-hydraulic proportional valves imported from Germany or other European countries. Therefore, Dadong CNC bending machines can issue warnings in case of overload.
- Operate the machine within the rated pressure range; otherwise, serious accidents may occur.
- The compensation system under the lower die of the hydraulic bending machine ensures higher bending accuracy.
- When purchasing a bending machine, it is advisable to choose one equipped with a compensation system. Dadong CNC bending machines are usually equipped with a compensation system.
