When equipment, testing, and parameters meet all requirements, the operator's skill level and operational standardization directly determine the straightening accuracy. Human-induced errors are often the primary cause of precision loss. Therefore, standardizing operational procedures and enhancing operators' professional competence are essential safeguards for precise straightening accuracy control.
The pre-operation preparation procedure must be strictly followed. Operators must complete professional training, thoroughly understand the equipment's performance, structure, and operational methods, and pass the assessment before commencing work. First, conduct a comprehensive equipment inspection: verify the frame's stability and secure the anchor bolts; check the hydraulic system for leaks and ensure the oil pressure gauge indicates accurately; confirm the detection and control systems are functioning properly. Next, perform pre-treatment on the lamp post workpiece: remove surface contaminants such as oil, rust, and burrs; inspect for cracks or other critical defects, and prohibit straightening operations on defective workpieces. Simultaneously, adjust the support rollers and fixture positions according to the workpiece specifications to ensure stable placement and precise positioning, thereby preventing straightening accuracy issues caused by clamping deviations.
Standardize the straightening operation procedure. During straightening, operators must stand in a safe position beside the equipment, closely monitoring workpiece deformation, equipment status, and pressure fluctuations. For first-time straightening or when changing workpiece models, begin with low-parameter trial adjustments and progressively refine settings based on trial results to avoid excessive pressure. For heavily bent workpieces, implement segmented multiple straightening to prevent over-straightening that could cause workpiece fractures or equipment damage. If abnormal vibrations or unusual noises occur during straightening, immediately press the emergency stop button, disconnect power, troubleshoot, and resume operation. After completing the process, follow standard shutdown protocols, clean the equipment and work area, and ensure the equipment is in optimal condition.
Enhance operators 'skill development and experience accumulation. Operators' judgment significantly impacts straightening accuracy, with proficient technicians making precise parameter adjustments based on actual workpiece deformation. Companies should regularly conduct training sessions to share straightening expertise, providing targeted guidance on challenges for different material types and lamp post specifications. Establishing an operational evaluation system will motivate skill improvement. Additionally, operators should document parameter settings, inspection data, and precision metrics during straightening processes to build an experience repository. This will serve as a reference for future similar workpieces, gradually improving overall operational accuracy.
