The W11-4x3200 is a high-performance mechanical plate rolling machine featuring an upper-roll adjustment design for precise sheet metal bending. Constructed with heat-treated 45# steel rollers, the main motor drives the lower rolls through a reduction gear system, while the upper roll is electronically adjusted for vertical positioning. This robust machine includes an integrated unloading device and balancing mechanism, allowing for the easy removal of finished circular workpieces. It is an ideal, reliable solution for bending plates up to 4mm thick across a 3200mm width.
This machine is an upper roll adjustment type. The upper roll is located between the two lower rolls and is driven by a screw to move upward/downward and bend steel plates.
The equipment consists of two parts: the working parts and the drive system. The working parts consist of left and right bearing plates, one upper roll, two lower rolls (the material of these three rolls is heat-treated 45# steel), a lifting screw, and worm gear, etc. The lower rolls drive the upper roll to move. The upper roll can be adjusted upward/downward. The drive system consists of a main motor, a main reducer gear, and other auxiliary parts.
The lower rolls are driven by the main motor and the main reducer gear. The main shaft of the main reducer drives the two lower rolls through a set of gears, and the direction is adjusted by the main motor.
The upper roll is lifted by an auxiliary motor and a secondary reducer, driving the worm gear and worm wheel at the position of the left and right rolling bearing plates.
The unloading device is used for bending circular workpieces. When the unloading upper roller moves to its upper limit position, the balancing device at the upper roller end strikes the upper roller to remove the workpiece.

The highly durable carbon steel (C45) rolls are precision machined on CNC lathes to ensure high accuracy and prevent any notch effects. The working surfaces of the rolls are induction hardened to achieve a hardness level of HRC 48-52.
The hydraulic system is manufactured in strict accordance with national and industrial standards. Energy saving and power consumption factors have been taken into consideration. Specialized sealants are used at connection points to effectively prevent leaks and facilitate maintenance.
The machine's bottom roller and side rollers are synchronized via a PLC control system.
The dual-roll drive completely eliminates slippage during the pre-bending process. The fully driven upper and lower rollers ensure precise feed control on both sides of the sheet, and synchronous movement ensures reliable and stable feeding.
The 10-inch large screen system features automatic calculation and automatic generation of the rolling process. It is equipped with a special independent operation panel and remote troubleshooting function, enabling one-click operation and providing powerful data storage and retrieval capabilities.
