Steel Bar Bending Machine

Equipment status verification

1. Mechanical components: Inspect the working wheel, bending die, and transmission gears for wear, cracks, or looseness (if the edge of the die is chipped, it should be replaced immediately to prevent slippage or deformation during steel bar processing). Confirm that there are no foreign objects blocking the feeding track and that the steel bars in the storage bin are neatly stacked (not exceeding the rated storage capacity of the equipment to prevent collapse).
2. Electrical system: Check if the power lines and data lines are damaged and if the grounding device is secure (to avoid the risk of leakage). After starting the touch screen, confirm that the PLC control system, servo motor, and emergency stop button respond normally (no error code should be reported before continuing the operation).
3. Lubrication and maintenance: Check the amount and quality of lubricating oil in the transmission parts according to the equipment manual. If insufficient, add the corresponding type of lubricating oil (do not mix different specifications of oil to prevent component jamming).

Raw materials and parameter matching

1. The reinforcing bars must be within the processing range of the equipment: Confirm that the diameter and material of the reinforcing bars match the model of the equipment. Check that the surface of the reinforcing bars is free from severe rust and bending to prevent material jamming during feeding.
2. Preset processing parameters: According to the specifications of the reinforcing bars and the radius of the bending arc, the pre-stored parameters can be called on the touch screen or manually calibrated. After setting the parameters, 1–2 pieces need to be trial-processed to verify that the accuracy meets the standards before mass production.

Personnel operation safety

• Operators must be trained before taking up their posts and be familiar with the operation process of the equipment. It is prohibited to wear loose clothing, jewelry, or have long hair (to prevent the transmission components from drawing them in). When processing, keep your hands away from moving parts such as work wheels and molds (it is strictly forbidden to push the steel bars directly into the curved area with your hands; a feeding auxiliary tool must be used).
• Warning signs must be set up in the operation area to prohibit non-operating personnel from approaching. If parameters need to be adjusted or cleaning is required during the operation of the equipment, the emergency stop button must be pressed first to shut down the machine. It is strictly prohibited to "start the machine for adjustment."

Equipment operation monitoring

1. Real-time observation of the equipment's operating status: Listen for any abnormal sounds from the transmission components (such as the "jamming sound" from abnormal gear meshing), feel the temperature of the motor housing (not exceeding 60℃; if it overheats, the machine needs to be shut down for cooling), and check the precision of the processed steel bars.
2. Avoid overloading operation: Process according to the rated production capacity of the equipment to prevent the motor and servo system from being overloaded for a long time. When the material gets stuck, the machine should be stopped first and the blocked steel bars manually cleared (do not forcibly start the feeding mechanism to avoid component cracking).

Equipment cleaning and reset

• After cutting off the power and gas supply, clean the steel bar debris and oxide scale on the workbench (blow them off with a brush or compressed air; do not directly rinse the electrical components with water). Disassemble the bending die and clean the impurities in the die grooves (to prevent the surface of the steel bars from being scratched during the next processing).
• Reset the feeding track and empty the remaining steel bars in the storage bin (to avoid deformation of the steel bars or damage to the track due to long-term stacking). Before turning off the touch screen, save the processing parameters and operation data of the day (for subsequent fault detection and production capacity statistics).

Short-term maintenance and record-keeping

• Tighten all connecting screws of the equipment and check the tightness of the belt (if it is too loose, it is prone to slipping; if it is too tight, it will accelerate wear). Record the operating duration of the equipment, the processing quantity, and abnormal conditions (such as error codes and the number of material jams) to provide a basis for regular maintenance.

Personnel safety prevention

1. Mandatory wearing of protective equipment: Operators must wear safety helmets, anti-crush protective gloves, and goggles (steel bar debris may fly during processing, risking eye injuries). If the equipment has a welding function, an additional welding mask and fire-resistant gloves must be worn.
2. Operation in violation of regulations is strictly prohibited: It is strictly forbidden to cross or lean against the equipment when it is in operation. Unauthorized modification of equipment components is prohibited (such as removing the protective cover or changing the position of the emergency stop button). Any modification must be confirmed by the manufacturer's technical personnel to avoid damaging the safety protection structure of the equipment.

Regular maintenance (follow the cycle specified in the manual)

1. Monthly: Replace the lubricating oil of the transmission parts and check the wear of the carbon brushes of the servo motor (replace if the wear exceeds 1/3). Calibrate the bending accuracy (compare with the standard sample, and adjust the sensor or mold position when the error exceeds the limit).
2. Every quarter: Disassemble and inspect the working wheel bearings, and replace the aged seals (to prevent lubricating oil leakage); test the sensitivity of the emergency stop button and overload protection device (to ensure that the power can be immediately cut off after being triggered).

Special Working Condition Adaptation

• If used in a damp and dusty environment, a waterproof cover and a dust filter should be installed (to protect the electrical system from erosion). Before being idle for a long time (more than one month), anti-rust oil should be applied to the surface of the mold and the working wheel, and dust-proof cloth should be used to prevent the components from rusting.

Pre-set emergency procedures

1. Leakage handling: If the equipment experiences leakage (such as an operator feeling an electric shock), the main power supply must be immediately cut off, and the circuit should be inspected by a certified electrician (non-professionals are prohibited from repairing electrical components).
2. Component failure: If the motor is smoking or the mold is cracking, stop the machine immediately and contact the manufacturer’s after-sales service (provide the equipment model and error code). Do not disassemble core components such as servo motors and PLC modules yourself.

Emergency Material Preparation

• Insulating gloves, fire extinguishers (dry powder or carbon dioxide type, suitable for electrical fires), and first aid kits (including tourniquets, iodophor, etc., for minor scratches) should be provided beside the operation area. Moreover, operators must be aware of their storage locations and usage methods.
