Plate Rolling Machine with Three Rolls and Four Rolls for Plate Bending Machine

Product Introduction

Rolling machine is sheet metal bending and correction machinery, dedicated to sheet metal forming bending work. The machine can complete the prebending of the end of the plate and the rolling of the cylindrical, curved workpiece, but also the rough shaping of the metal plate. Widely used in shipbuilding, boiler, aviation, bridge, hydropower, chemical, metal structure and machinery manufacturing industries.

Product Classification

Plate rolling machine due to the use of different fields, the type is also different. From the number of rolls, it is divided into three rolls and four rolls. Three rolls are divided into symmetrical three-roll plate rolling machine, horizontal down-regulating three-roller plate rolling machine, arc down-regulating plate rolling machine, universal three-roll plate rolling machine, hydraulic numerical control plate rolling machine. From the transmission of mechanical type and hydraulic type.

A. Three-roll bending machine with bottom rollers horizontal adjustment

Three roll bending machine is easy to operate intelligent metal rolling equipment, it has formed two kinds of asymmetric three roll rolling machine, from thin plate to thick plate, from the prebending end to the round one time to complete the whole process, the other rolling cone is very convenient.

Structural Characteristics:

a. The structure of this machine is composed of base, upper and lower roller support, main drive system, electrical system and so on. Base and frame adopt welding structure, strict requirements of weld quality, and stress elimination processing, in order to ensure that the machine has enough strength and stiffness under the working load, so as to improve the rolling precision.

b. The lower roller drive, the upper roller lift, all have electric execution, all the operation adopts electric centralized control, easy to operate.

c. Lower roll level adjustment: manual

Product Parameter:

B. Mechanical non - symmetrical three - roll plate rolling machine

This equipment is asymmetric three-roll plate rolling machine, used for bending a certain thickness of metal plate at room temperature into tubular, arc, without additional equipment, with pre-bending function. Its working principle is rotary bending deformation, this machine is necessary equipment of boiler, shipbuilding, petrochemical, cement, motor and other machine manufacturing industry .

Product Parameter:

C. Ship plat rolling machine

Ship plate rolling machine is special for shipbuilding, used for hull arc rolling and bending, optional automatic NC control and CNC computer control. Advanced design, compact structure, high strength, easy to operate, stable work, reliable quality.

Structural Characteristics:

a. All steel welded structure, equipment rigidity is strong, using the computer finite element analysis method to optimize the design calculation.

b. Both ends of the main roller of Marine winding machine are adjustable bearings.

c. The main roll is made of medium 45 steel forging, tempering, medium frequency quenching and other processes.

Product Parameter:

D. Up-Roller Universal Plate Rolling Machine

The upper roll of the universal three-roll plate rolling machine can move up and down and horizontally. The upper roll moves up and down to change the curvature of the bending plate. The upper roll moves back and forth to change the vertical and symmetrical position of the upper roll to the center line of the two lower rollers, so as to realize the bending of the end of the plate and meet various technological requirements required by bending.

In the production process, no additional equipment such as press is needed. After a feeding, the prebending and forming function of both ends of the plate can be completed without turning around. It can also be used for the correction of the forming workpiece.

The major structure of the device composed of up-roller part, bottom roller part, up roller level move part,support roller part, main drive part, tipping part, base board, balance part and so on.

Product Parameter:

E. Hydraulic symmetrical plate rolling machine

The Three-roll symmetrical hydraulic plate rolling machine has superior performance, compact structure and convenient operation.The upper roll lifting and overturning devices are driven by hydraulic pressure, and the main drive is driven by the motor through the triangle belt transmission reducer to drive the two lower rollers. The rolling flexibility is good. The upper roll lifting adopts displacement sensor to detect the digital display table, which can directly observe the upper roll working displacement to improve product efficiency and product quality.

The major structure of the device composed of upper roll lifting device, lower roll drive device, tipping device,upper roll balancing device, base plate, hydraulic system, electrical control system and so on.

Product Parameter:

F. Mechanical symmetrical three - roll plate rolling machine

The structure of this machine is the mechanical symmetrical up-regulating three-roll rolling machine. The upper roll moves vertically up and down in the symmetrical position of the center of the two lower rollers, which is obtained by the screw worm drive. The two lower rollers rotate, and the output gear of the reducer meshes with the gear of the lower rollers to provide torque for the rolling plate. The disadvantage of this machine is that the end of the plate needs to be prebent by other equipment.

Structural Characteristics:

The structure of this machine is composed of base, upper and lower roller support, main drive system, electrical system and so on. Base and frame adopt welding structure, strict requirements of weld quality, and stress elimination processing, in order to ensure that the machine has enough strength and stiffness under the working load, so as to improve the rolling precision.

The lower roller drive, the upper roller lift, all have electric execution, all the operation adopts electric centralized control, easy to operate.

Product Parameter:

G. Four-rolls plate rolling machine

Four roll rolling machine is sheet metal bending, correction machinery, dedicated to sheet metal forming and bending work. The machine can complete the prebending of the end of the plate and the rolling of the cylindrical, curved workpiece, but also the rough shaping of the metal plate. Widely used in shipbuilding, boiler, aviation, bridge, hydropower, chemical, metal structure and machinery manufacturing industries. 

The pre-bending straight edge is small, the roundness of the circle is good, and the whole busbar can be rolled conical workpiece. The ability to roll small circle is strong, is the highest efficiency and ability of the universal rolling machine.

Compared with the symmetrical three-roll plate coiling machine, the four-roll plate coiling machine can prebend the end of the plate directly without the help of other equipment mold, and the remaining straight edge is smaller; Compared with the asymmetric three-roll plate coiling machine, it can be rolled into the workpiece without the plate turning. Not only improve the efficiency, ensure the quality of the workpiece, and the process is simple, easy to operate, reduce the labor intensity of workers.
