HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank

Overview of HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank

The HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank is designed specifically for oil tank manufacturing, suitable for cold bending metal plates up to 8mm in thickness and 8000mm in width into cylindrical shells. The HDLW12-8×8000 adopts a four-roll configuration consisting of one upper roll, one lower roll, and two side rolls. The upper roll serves as the main drive roll, the lower roll performs clamping and feeding functions, and the two side rolls execute pre-bending and bending operations. The machine frame and roll length of this 4 Roller Plate Rolling Machine For Oil Tank are configured for large oil tank shell processing, supporting one-pass rolling of extra-wide plates.

Product Introduction

Key Advantages of HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank

- Extra-wide processing capacity: The HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank features a maximum rolling width of 8000mm, matching large oil tank shell manufacturing specifications.
- Four-roll configuration: This 4 Roller Plate Rolling Machine For Oil Tank eliminates flat ends on plates, allowing continuous pre-bending and rolling with reduced material waste.
- Hydraulic drive system: Each roll movement on the HDLW12-8×8000 is independently controlled by the hydraulic system, providing stable rolling force output.
- Independent side roll adjustment: Each side roll can be controlled separately, supporting conical cylinder rolling.
- Reinforced structural rigidity: The frame and housing are constructed from thickened steel plates with stress-relief treatment, accommodating off-center loads during wide plate rolling.

The HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank is widely used in the following applications: large vertical oil tank shell rolling, horizontal oil storage tank shell forming, chemical storage tank and atmospheric vessel cylinders, large cylindrical structures for water treatment equipment, cement mixer drum shell processing, and large ventilation ducts and dust collector cylinders.

Common Issues and Solutions for HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank

Issue 1: Inconsistent diameter at two ends of the cylinder when rolling extra-wide plates
Possible causes: Plate not fed perpendicular to the roll face; unbalanced output torque from dual drive motors.
Solution: Mark a centerline on the plate and align it with the roll face centerline before rolling on the HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank; check synchronization of the dual-motor drive system and adjust VFD or transmission parameters.

Issue 2: Excessive axis straightness deviation on the rolled cylinder (bent axis)
Possible causes: Uneven pressure distribution across ends of the upper or side rolls; insufficient frame rigidity or foundation level deviation.
Solution: Check synchronization of hydraulic cylinders on both ends of the HDLW12-8×8000, and adjust flow divider valves if necessary; recheck foundation levelness and frame installation condition.

Issue 3: Incomplete pre-bending curvature at plate ends
Possible causes: Insufficient side roll penetration depth; burrs or hard spots on plate edges.
Solution: Increase side roll pre-bending stroke based on plate thickness on this 4 Roller Plate Rolling Machine For Oil Tank; grind plate edges before rolling if necessary.

Operational Precautions for HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank

- For 8000mm extra-wide plates, auxiliary feeding devices (e.g., support racks or feeding platforms) are recommended to reduce plate sagging when using the HDLW12-8×8000 4 Roller Plate Rolling Machine For Oil Tank.
- The machine foundation must be constructed according to the manufacturer's drawings, with length and width exceeding the machine footprint to meet ground bearing capacity requirements.
- Supply voltage fluctuation should not exceed ±10% of rated voltage; soft starters are recommended for high-power motors.
- Monitor synchronized feeding at both plate ends during rolling to avoid off-center loads that may damage roll surfaces or bearings.
- Operators must understand off-center load control methods for extra-wide plate rolling machines and be familiar with emergency procedures.
