The whole machine weighs about 680kg, with a compact and stable structure, suitable for both factory centralized processing and on-site mobile operation. Operating within the parameter range is the primary premise to ensure the service life and processing quality of the rebar bending machine.
5. Step-by-Step Standard Usage Instructions for Rebar Bending Machine
Scientific and standardized operation is the core to improve efficiency and reduce failure rates. The complete operation process is divided into pre-operation inspection, parameter calibration, trial operation, formal processing, and post-operation maintenance, which is applicable to all CNC rebar bending machine models.
Pre-Operation Comprehensive Inspection: Before starting the equipment, check the integrity of the fuselage structure, confirm that the bending mandrel and positioning baffle are installed firmly without wear and looseness. Inspect the lubrication of gears and bearings, replenish lubricating oil regularly to avoid dry friction. Meanwhile, check the circuit and grounding safety to ensure no leakage or hidden circuit troubles. Clean up on-site sundries to guarantee a smooth operating area.
CNC Parameter Calibration: According to the construction drawing standards, input the required bending angle, rebar specification, and processing spacing on the touch screen. For repeated processing of fixed specifications, store the parameters for one-click calling to improve batch processing efficiency. Complete zero calibration of the equipment to eliminate mechanical errors and ensure precision bending.
Empty Machine Trial Operation: Start the equipment for 1-3 minutes of empty operation, observe whether the turntable runs stably, whether there is abnormal noise or jamming. After confirming normal operation, conduct single-piece trial bending, measure the finished rebar size and angle with professional tools, and adjust parameters timely if errors occur.
Formal Batch Processing: After the trial product is qualified, carry out continuous feeding and bending operation. Place the steel bars stably according to the positioning scale, avoid forced feeding and overload processing. During operation, monitor the equipment running status in real time, and stop the machine immediately for inspection in case of abnormal vibration or noise.
Post-Operation Maintenance & Shutdown: After daily work, cut off the power supply completely, clean the metal debris and dust on the equipment surface and rotating parts, and lubricate the key transmission components. Sort out the finished rebars and record the equipment operation status to facilitate subsequent maintenance and inspection.
