HDLW11-120X3500 Symmetrical 3 Roller Plate Rolling Machine

Key Advantages of HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine

- Hydraulic drive system: The main cylinder of the HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine delivers 130 tons of rolling force, meeting processing requirements for medium-to-high strength plates.
- Synchronized torque output: Torque is distributed to both lower rolls via a gear distribution box, maintaining equal rotational speed and reducing plate slippage.
- Upper roll position indication: The HDLW11-130X3000 is equipped with digital or mechanical displacement display, allowing operators to control penetration based on set travel.
- Overload protection: A relief valve installed in the hydraulic circuit automatically releases pressure when exceeding the set value on this Symmetrical 3 Roller Plate Rolling Machine.

Product Specifications of HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine

The HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine features a maximum plate thickness of 130mm for cold bending of Q235 material and a maximum plate width of 3000mm. The rolling method is symmetrical rolling, with the upper roll positioned centrally above the two lower rolls, resulting in short flat ends on plates. The roll surface is induction-hardened to achieve a surface hardness of HRC45–50. The lubrication system includes centralized or manual lubrication points for bearings and gears. The hydraulic system comprises an independent tank with return filtration and air or water cooling. These specifications make the HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine a reliable choice for medium-to-heavy plate forming applications.

Application Scenarios of HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine

The HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine is widely used in the following applications: pressure vessel shell rolling, boiler casing curved plate forming, pipeline prefabrication, construction machinery boom bending, and curved structural components in steel buildings.

Common Issues and Solutions for HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine

Issue 1: Inconsistent diameter at two ends of the rolled cylinder
Possible causes: Plate not fed perpendicular to the roll axis; uneven wear on the two lower rolls.
Solution: Mark a centerline on the plate and align it with the roll face before rolling on the HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine; inspect diameters and surface condition of both lower rolls, and replace them as a pair if necessary.

Issue 2: Insufficient hydraulic system pressure
Possible causes: Clogged hydraulic oil filter; shifted relief valve setting or stuck valve spool.
Solution: Replace the return filter element; readjust the relief valve pressure according to the machine manual and check for smooth spool movement.

Issue 3: Unusual noise during rolling
Possible causes: Insufficient lubricating oil in the gear distribution box; excessive bearing clearance or bearing damage.
Solution: Check oil level in the gearbox and refill to the specified level; stop the HDLW11-130X3000 and inspect bearing clearance, replacing damaged bearings.

Operational Precautions for HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine

- The HDLW11-130X3000 Symmetrical 3 Roller Plate Rolling Machine requires a horizontal concrete foundation with thickness and reinforcement sufficient for the total weight and dynamic loads.
- Supply voltage fluctuation should not exceed ±10% of the rated voltage.
- Check hydraulic oil level before each start-up; the level should be above the middle mark of the sight glass.
- Do not roll plates exceeding the specified thickness or width limits.
- Operators must be familiar with the emergency stop button location and machine operation procedures.
