Daily Maintenance (Recommended Time: 30-45 Minutes)
1. Clean the forming rollers and welding electrodes
Cleaning Frequency: After the end of daily production
Data Reference: Maintaining a roller surface roughness Ra ≤ 0.8 μm can reduce weld rework by 12%
2. Lubricate the drive chain and bearings
Lubricant Amount: 3-5 ml per lubrication point
Data Reference: Proper lubrication can reduce transmission component wear by 20%
3. Check the cooling water circulation
Water temperature: Maintain 20-30°C
Water pressure: 0.2-0.3 MPa
Data Reference: A properly functioning cooling system can extend the life of the welding electrodes by 15%
Weekly Maintenance (Recommended Time: 1-1.5 Hours)
1. Measure the gap between the forming rollers
Gap tolerance: ±0.02 mm
Data Reference: A stable gap can keep the pipe ovality within 0.3%
2. Check electrical wiring and cooling system.
o Electrical contact resistance: ≤0.05 Ω
o Reference: Secure wiring can reduce electrical downtime by 8%.
3. Weld flaw detection inspection
o Inspection ratio: ≥5% per batch
o Reference: Prompt detection of defects can reduce the risk of batch scrap by 10%.
Monthly maintenance (recommended time: 3-4 hours)
1. Apply anti-rust oil to the machine frame and roller system.
o Anti-rust oil film thickness: 5-10 μm
o Reference: Anti-rust treatment can reduce roller corrosion by 25%.
2. Replace worn guide plates or scrapers.
o Wear limit: Replace when thickness decreases ≥10%.
o Reference: Timely replacement can improve forming stability by 18%.
3. Calibrate the accuracy of the in-line diameter gauge.
o Accuracy requirement: ±0.01 mm
o Reference: Accurate diameter measurement can reduce dimensional deviations. 15%
Annual Maintenance (Recommended Time: 1-2 Days)
1. Bearing and Motor Overhaul
Bearing Clearance: Meets Manufacturer's Standards
Data Reference: Annual Overhaul Can Extend Bearing Life by 20%
