About Three Roll Plate Rolling Machin

A Three Roll Plate Rolling Machine (also called a 3-Roll Bending Machine) is a sheet metal forming machine used to roll and bend flat metal plates into cylindrical or conical shapes. Its widely used in metal fabrication, boiler making, shipbuilding, and pressure vessel industries.

Working Principle:

The machine has three rollers arranged either in a pyramid (one top roll, two bottom rolls) or initial pinch configuration.
The top roll presses the plate while the two lower rolls rotate, pulling and bending the plate.
By adjusting the roller positions, the plate gradually bends into the desired diameter.

Main Types of 3-Roll Plate Rolling Machines:

Initial Pinch Type
- Top roll fixed, one lower roll adjustable.
- Requires plate to be pre-bent before rolling.
- Best for thin to medium plates.
Pyramid Type (Double Pinch)
- Both lower rolls adjustable.
- Can perform pre-bending and rolling without taking the plate out.
- Suitable for thicker plates.

Advantages:

Can roll cylinders, cones, and arcs.
Simple operation and robust design.
Suitable for medium to heavy-duty fabrication.
Lower cost than 4-roll machines.

Common Applications:

Manufacturing tanks, boilers, silos.
Shipbuilding and marine industry.
Aerospace and automotive exhaust systems.
Structural fabrication for pipes and cones.

Typical Specifications (varies by model):

Plate Thickness Capacity: 2 mm 100 mm.
Plate Width: 1000 mm 5000 mm.
Roll Diameter: 100 mm 800 mm.
Rolling Speed: 3 6 m/min.
Drive: Manual, motorized, or hydraulic.

FAQ's of Three Roll Plate Rolling Machin:

Q: How does the Three Roll Plate Rolling Machine benefit industrial operations?

A: This machine enhances metal forming productivity by enabling precise bending of mild steel plates up to 12 mm thick and 2500 mm wide. Its semi-automatic control system and robust design ensure consistent quality, higher throughput, and reduced manual labor, making it suitable for heavy-duty industrial applications such as manufacturing and construction.

Q: What types of materials can be processed with this machine?

A: The primary raw material for this plate rolling machine is mild steel. Its strong alloy steel rolls and adjustable bending strength (up to 150 MPa) make it suitable for various sheet metal projects requiring rolled plates or cylindrical shapes, commonly used in construction and metalworking industries.

Q: When should I use the pre-bending feature?

A: You should use the pre-bending feature when you need precise edge forming before the actual rolling process. Pre-bending ensures that the ends of the plate are properly shaped, minimizing flat portions and achieving a uniform curvature for high-quality finished components.

Q: Where is the machine manufactured and is customization available?

A: The machine is manufactured in India and can be customized in terms of color to suit client or company preferences. It's distributed by dealers, suppliers, and manufacturers across India for industrial users seeking reliable metal forming solutions.

Q: How does the centralized manual lubrication system work?

A: The centralized manual lubrication system allows operators to deliver lubricant to critical moving parts from a single location. This ensures even lubrication, reduces wear and tear, and facilitates easy routine maintenance, thereby extending the machine's operational life and performance.

Q: What safety features are provided with the machine?

A: An emergency stop switch is integrated into the electrical control panel, allowing operators to quickly halt operation if a safety hazard arises. This feature is essential for safe machine handling in busy industrial environments.

Q: What is the process for adjusting the bending angle and radius?

A: The machine offers an adjustable bending angle from 0 to 360 degrees and a minimum bend radius of 50 mm. Operators can control these parameters via the electrical panel and back roll movement system, which can be set to manual or hydraulic control based on the specific application requirement.
