Introducing the CNC 4 Roll Hydraulic Steel Plate Bending Machine - an advanced Automatic Sheet Metal Roller Bender designed for ultimate precision and efficiency. Crafted to handle Iron, Aluminum, and a variety of metals, this state-of-the-art machine excels in bending rolls, pipe, and tube rolling, as well as forming and pressing tasks.
Our Automatic Hydraulic 4 Roll Steel Bending Machine for Metal Sheets stands unrivaled in the global market, hailed as the fastest, safest, most precise, and user-friendly plate rolling machine. This state-of-the-art, fully hydraulic 4-roll bending machine, equipped with advanced pre-bending capabilities, can handle rolls length up to 6,000mm and plate thickness up to 150mm.
This advanced design offers numerous benefits, including:
1. Horizontal plate introduction, eliminating the need for tilting as seen in three-roll double pinch machines.
2. Instant squaring against the back roll, significantly reducing the risk of mismatched end conditions.
3. Space efficiency, requiring only one side of the machine for plate introduction.
4. Drastically reduced flat-end due to superior pre-bending, thanks to the clamping roll that reaches precise tangent points of the top and bottom rolls.
5. Unmatched speed in rolling a can, needing only a single position for each side bending roll.
6. Comprehensive cylinder completion in one pass (within suitable capacity), including edge pre-bending.
7. Eliminates the need for pre-bending both ends before rolling the entire cylinder, as required with a 3-roll machine.
8. No removal, turning, or re-insertion of the plate, unlike the 3-roll single pinch machines.
9. Potentially 50-80% faster and more productive than any three-roll style machine.
10. Highly suitable for CNC operations due to optimal plate control, clamped securely between the top and bottom rolls until the process is completed.
The Four Roll Design is recommended for clients who:
1. Desire CNC operations with minimal operator skill dependency.
2. Seek consistent, high-quality rolled products.
3. Aim for high productivity and increased profitability.
4. Require precision and quality improvements in their outputs.
5. Need efficient handling of larger plates with a focus on production and safety.
6. Are newcomers to plate rolling, as it is the easiest machine to operate.
1. Extremely robust structure machined with CNC control machines
2. Two hydraulic motors coupled to planetary gear units for the rotation of the two central rolls
3. Hardened rolls / Hardened and polished rolls
4. Separate control desk on wheels
5. Hydraulic opening of shoulder by control desk
6. Hydraulic inclination of lateral rolls for conical bending directly from control desk
7. Numerical control for automatic production
8. Movements of rolls on swing guides to reduce flat part
9. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.
10. Rolls rotation on high resistance selfaligning bearings
11. Rolls Cambering: know how variable cambering to avoid reel and barrel effect to increase bending performance and precision
(1) How long is the service life of your product?
The longevity of our Automatic Hydraulic 4 Roll Steel Bending Machine for Metal Sheets greatly depends on the operator's skill level, experience, and daily working hours. When maintained properly according to our guidelines, this robust machine can last up to an impressive 10 years. However, it's important to note that excessive daily operation, such as running for 12 hours or more, can adversely affect its lifespan.
(2) What are the specific categories of your products?
Nantong Weihua Import & Export Co., Ltd proudly offers three primary categories of roll bending machines: Mechanical 3 Roller, Hydraulic 3 Roller with Pre-bending, and Hydraulic 4 Roller with Pre-bending. Each category is designed to meet diverse industrial needs with optimal efficiency.
(3) What are the specifications and styles of existing products?
Our product range includes both light-duty and heavy-duty rolling machines, catering to thicknesses from 6mm to 150mm and widths ranging from 1000mm to 12000mm. Additionally, we specialize in custom configurations to meet unique customer requirements, such as smaller rolling diameters and specialized applications for industries like oil pipelines, wind towers, and loaders.
