3 Rolls Mechanical Plate Rolling Machine

3 Rolls Mechanical Plate Rolling Machine is a three rolls mechanical plate rolling equipment, which is divided into three rolls mechanical symmetrical plate rolling machine, three rolls mechanical asymmetric plate rolling machine, and three rolls mechanical vertical plate rolling machine. It is mainly used for bending metal plates in the cold work process, bending them into various cylindrical tubes and arcs of different diameters, and is widely used in mechanical industries such as boilers, chemicals, mines, construction, shipbuilding, etc.

This machine consists of two main parts: the working part and the transmission part on the overall chassis to be welded. The working part consists of left and right roller bearing seats, one upper roller, two lower rollers, lifting screw worm gears, and some auxiliary parts. The lower roller is the main driving roller, and the upper roller is the passive roller. The upper roller can be adjusted up and down along the height direction. The transmission part consists of the main motor, main reducer, and other auxiliary parts.

The transmission of the lower rollers is achieved by the main motor through the main reducer. The output shaft of the main reducer is transmitted to the two lower rollers through a set of gears, and the change in the rotation direction of the roller shaft is obtained by reversing the direction of the main motor. The implementation of the lifting motion of the upper roller is achieved by the auxiliary motor driving the worm gear and worm gear mechanism under the bearing seats at both ends of the roller through the auxiliary reducer, causing the screw nut fixed on the worm gear to rotate, thereby causing the lifting screw to move up and down.

The unloading device is designed to remove the workpiece after the cylindrical part is rolled. Before unloading, the upper roller rises to its position, and a balancing device is used to press the upper roller at the tail end. Then, the pin shaft on the tilting bearing seat is pulled out, and the tilting bearing seat is flipped over. The rolled workpiece can be released from one end of the upper roller.

Features of 3 Rolls Mechanical Plate Rolling Machine

Excellent performance: 3-roll mechanical coiler is connected by high-quality couplings for stable working performance and durability. The transmission structure and lifting mechanism components, such as screw rods, worms, gears, etc., are all forged parts.

Multi-functional design: Equipped with enhanced roll cone device, Siemens electrical components, hydraulic tipping frame, etc. to meet different rolling needs. Forged solid rollers and subjected to high standard heat treatment process.

Efficient production: Adopting advanced linear guide structure and high-quality materials, it can realize high-speed rolling and improve production efficiency. Large and medium-sized models use YZR lifting motors to ensure the stability of the instantaneous current during startup. And it adopts ZSY hard tooth reducer, providing high torque and durability.

Convenient maintenance: Forged parts of screws, worm gears and gears are specially treated to ensure wear resistance and stability.
