To prevent cable tray deformation during cable tray forming machine production, optimization is required in multiple aspects, including mold design, process parameters, and equipment maintenance. Specific measures are as follows:
Optimizing Mold Structure
Use a symmetrical mold design to ensure uniform force distribution between the rollers; adjust the mold gap according to the cable tray specifications, maintaining an error within ±0.1mm to prevent localized extrusion deformation; and add reinforcing ribs in key forming areas to increase mold rigidity.
Precise Process Parameter Control
Set an appropriate roller speed based on material properties to avoid stress concentration caused by excessive speed; optimize the forming passes through finite element analysis to reduce unnecessary bending; and adjust the pressure gradient between passes to ensure gradual material deformation.
Material Pretreatment and Quality Control
Level the raw materials to eliminate internal stress; strictly control the sheet thickness tolerance to ±0.05mm to prevent deformation caused by uneven thickness; and select high-quality sheet materials that meet standard yield strength and elongation standards.
Equipment Maintenance and Calibration
Regularly check the parallelism of the rollers and calibrate them promptly if the deviation exceeds 0.2mm. Lubricate and maintain transmission components to prevent deformation caused by equipment vibration. Calibrate the tension of the unloading rack to maintain stable material flow.
Production Process Monitoring
Install sensors to monitor pressure and displacement data in real time during the forming process, automatically alarming when an anomaly occurs. Spot-check the bridge flatness every 10-20 pieces, measuring diagonal deviation with a square. Immediately adjust any deviations.
Standardized Operation and Storage
Operators must follow standard procedures for mold changes and commissioning to avoid improper operation. Finished products should be stacked in layers using dedicated racks, with each layer no more than 1.5 meters high to prevent deformation under heavy pressure. Secure and protect them during transportation to avoid collisions.
