Tube Roller Bender Sheet Metal Bending Machine 4 Roll Plate Rolling Machine
Our company adopt Italy advanced swing arm technology, combined with the characteristics of domestic products, developed 4 roll plate rolling machine, patent number ZL200820161151.5, its performance is superior to domestic equivalent products, with high efficiency, low energy, easy operate etc.
4 roll plate rolling machine, driven by the top and bottom rolls, single unit high torque hydraulic motor and planetary gear box are directly mounted onto each driving roll to ensure a smooth feed through of the plate, the bottom roll can be vertically moved to clamp the plate, the side rolls move up and down on planetary swing guides, all four rollers use spherical roller bearings, the advantage of this machine is that it can complete the pre-bending of both ends and rolling at one time. It can also perform certain shaping and leveling on the metal sheet, and smallest flat ends.
1. Extremely robust structure machined with PLC control machines
2. Oversized dimensions of hydraulic system and components to withstand heavy use and prolong durability with low maintenance
3. Two hydraulic motors coupled to planetary gear units for the rotation of the two central rolls
4. Hardened rolls / Hardened and polished rolls
5. Separate control desk on wheels
6. Hydraulic opening of shoulder by control desk
7. Hydraulic inclination of lateral rolls for conical bending directly from control desk
8. Numerical control for automatic production
9. Movements of rolls on swing guides to reduce flat part
10. It can be used to roll tubes, tube segments, rounded boxes, ovals or other shapes.
11. Sheet width: Max. 6000 mm, sheet thickness: Max. 150 mm for cold bending
12. Side rolls are free for rotation and upwards downwards movements are hydraulic powered
13. Top and bottom rolls are driven by hydraulic and gearbox. Bottom roll's vertical movements are hydraulic powered
14. Rolls rotation on high resistance selfaligning bearings
15. Rolls Cambering: know how variable cambering to avoid reel and barrel effect to increase bending performance and precision
The warranty period of the equipment is 1 year, and the supplier shall be responsible for solving any quality problems in the equipment within 1 year.
During the warranty period, the buyer has the ability to resolve the fault by himself. In the event of a major fault, the supplier will give a clear answer within 24 hours after receiving the notice from Party A.
During the equipment warranty period, the supplier shall provide timely and free maintenance services for all types of equipment failures, and any non-human-caused parts damage shall be replaced free of charge in a timely manner. The warranty period of the replaced parts shall be recalculated from the replacement date.
(1) Earth moving machines
In the earth moving sector, bending rolls are useful in the production of buckets. Normally in high-strength and wear-resistant steel, buckets can be of various shapes and are constructed using CNC controlled automatic bending of metal plates. According to the various production needs, we offers 3-roll or 4-roll plate bending rolls complete with automation and ideal for mass production of buckets.
(2) Truck containers, Road/railway tankers
Tanks for the transport of liquid foodstuffs, fuels and other substances are manufactured in one piece in order to limit the use of circumferential welds. In the most varied shapes (circular, oval and polycentric), road and railway tankers are constructed using CNC roll bending of steel or aluminium sheets with thicknesses ranging from 3 to 15 mm and width of 3 m, 6 m, 8 m or 10 m, depending on the various applications.
(3) Steel structure
Using the right equipment, you can manufacture steel structures such as bent segments, pipe structures, cones domes etc.
Why we use two hydraulic motors for 4 roller bending machines?
1. The upper and lower rollers can clamp the steel plate to prevent it from slipping when bending.
2. It is convenient for bending conical parts, elliptical parts and special-shaped products.
3. When using the CNC function, the rolling effect is better.
