Busbar bending machine is a key tool in electrical equipment installation, mainly used to bend busbars to specified angles as per design requirements. Proper operation ensures processing accuracy and improves work efficiency. The core operation points and safety precautions for busbar bending are listed below.

I. Preparation Before Processing

1. Equipment Inspection: Check that the machine’s dies, hydraulic system and control system are in normal condition, and that the die model matches the busbar specification.

2. Material Preparation: The busbar surface must be flat and burr‑free, with dimensional tolerance controlled within ±0.5mm. Level the busbar if necessary.

3. Die Adjustment: Select appropriate dies according to the required bending angle. Adjust the gap between upper and lower dies to match the busbar thickness, and perform a pre‑press test to verify bending effect.

II. Standard Operation Procedure

1. Positioning and Fixing: Place the busbar on the bending machine workbench and secure it with positioning pins or clamps to ensure alignment with the dies and prevent shifting.

2. Single Bending: Start the machine and apply pressure slowly to avoid over‑bending and deformation. Refer to the machine manual for bending pressure suitable for different busbar thicknesses.

3. Angle Inspection: After each bending operation, check the angle with an angle ruler or try square to ensure it meets design requirements (e.g., 90°, 45°, etc.).

III. Troubleshooting for Common Problems

1. Busbar Deformation: If wrinkles appear on the surface, reduce bending pressure and increase pre‑press cycles. For severe deformation, replace the dies or re‑level the material.

2. Dimensional Deviation: Correct by fine‑tuning the die gap (generally 1.1–1.3 times the busbar thickness) to ensure consistent dimensions in continuous bending.

3. Hydraulic System Abnormality: If insufficient pressure or leakage occurs, stop the machine immediately to check hydraulic oil level and pipeline sealing. Do not operate with faults.

IV. Safety Precautions

1. Never place hands between the dies and the busbar during operation to prevent pinching injuries.

2. Do not adjust dies or clean the machine while it is running. Perform these actions only after power off and machine shutdown.

3. Regular Maintenance: Check hydraulic oil quality weekly, replace hydraulic oil every six months, keep dies clean and apply rust inhibitor.

The accuracy of busbar bending directly affects the installation quality of electrical equipment. Operators are advised to strictly follow the above specifications and adjust parameters according to actual working conditions to ensure processing efficiency and safety.
