Manufacturing Process Highlights
Rollers:
Forged from cast steel ingots → Heat treated (hardening & tempering) → UT flaw detection → Final machining
Large Forgings:
Cylinders, gears, and shafts undergo ultrasonic flaw detection, annealing, and precision machining
Welded Structures:
Racks, chassis, and boxes are welded with strict inspections (chemical, mechanical, RT/UT flaw tests), annealed, and finished with vibration stress relief
Working Principle of the CNC 4-Roller Plate Bending Machine
Key Features
- Full Hydraulic Drive: Provides higher safety, stability, and efficiency, with up to 60% energy savings compared to traditional machines.
- Programmable Control: Features a PLC-controlled system for automated, precise operation with a touchscreen interface and digital display.
- Advanced Clamping System: Adjustable pressure via hydraulic station valve ensures no slippage during rolling, increasing productivity by 50–80%.
- High Precision Pre-Bending: Capable of rolling cylinders with diameters as small as 1.3x the upper roll diameter, minimizing straight edge after pre-bending.
- Permanent Lubrication System: Ensures maintenance-free bearing life with automatic lubrication and block alarm.
