Heavy Duty U Bolt Making Machine Full Automation Low Maintenance
Heavy Duty U Bolt Making Machine Built to Withstand Demanding Production Environments and High Volume Output
Feature:
Full Automation & Labor Cost Optimization
Integrates automatic feeding, bending, thread rolling and discharging in one line; only 1 staff is needed for supervision, cutting labor costs by 60% compared with semi-automatic models.
High Precision & Ultra-low Rejection Rate
Achieves ±0.05mm dimensional tolerance and uniform thread forming; optimized transmission structure minimizes workpiece deformation, with the overall rejection rate controlled below 0.3%.
Multi-spec Adaptability & Quick Changeover
Compatible with U-bolts of M6–M30 diameters and 50–500mm lengths; die replacement can be completed within 10 minutes, flexibly matching small-batch and mass production orders.
Energy-saving & Low Maintenance Cost
Adopts frequency conversion speed regulation technology to save 25% energy; key components are made of high-hardness alloy steel, with 8+ years of service life and only simple lubrication required for routine maintenance.
