W11-20 * 2500 Plate Rolling Machine

Overview:

This machine belongs to a three roll symmetrical plate rolling machine, which is used to roll low-carbon steel and low-alloy steel into cylindrical shapes at room temperature. The upper roller can be vertically raised and lowered. When rolling, the two lower rollers are driven by a motor and a reducer. Due to the unchanged elevation of the lower roller, it is convenient for feeding and operation.

This machine is an essential equipment for industries such as boilers, shipbuilding, petrochemicals, motors, cement, and others. This machine has a compact structure and is easy to operate, making it a widely used small and medium-sized rolling equipment in China.

2、 Main technical parameters of the equipment

3、 Working principle and characteristics of the equipment

The structure is in the form of a three roll symmetrical structure,The upper roller moves vertically up and down at a symmetrical position in the center of the two lower rollers,Obtained through the transmission of a lead screw and worm gear, the two lower rollers rotate and provide torque for the rolled sheet by meshing with the lower roller gear through the output gear of the reducer.

From the diagram1.1Main motion refers to the winding of the upper rollerO1The lower rollers are wound separatelyO2、O3Rotate clockwise or counterclockwise. Auxiliary motion refers to the upward or downward movement of the upper roller.

It is driven by two lower rollers as the driving wheel, which are driven by the driving machine, coupling, reducer, and open gear pair. When the upper roller is working, it is driven by the frictional force between the steel plates. At the same time, as a driven shaft, it plays a role in adjusting compression. Controlled by a separate transmission system, the main components are: upper roller lifting motor, reducer, worm gear pair, screw rod, and screw nut. During operation, the worm gear pair rotates the inner screw of the worm gear, causing the screw rod and upper roller bearing seat to move up and down. The two lower rollers can rotate in both directions, and under the pressure of the upper roller, the lower roller rolls repeatedly to achieve the desired curvature of the sheet metal and form the expected shape.

4、 Structural characteristics of equipment

The equipment mainly consists of an upper roller device, a lower roller deviceThe main transmission system, balance device, chassis and other components are composed.

1.Upper roller device：The upper roller device includes an upper roller, an upper roller bearing seat, and sliding bearings.

2.Lower roller device：The lower roller device includes two lower rollers, lower roller wall panel, sliding bearings, worm gear transmission mechanism, etc.

3.Main transmission system: The main transmission system consists of a main motor, a reducer, output gears, etc.

The system can rotate in both forward and reverse directions, providing working power. It transmits torque to the lower roller through the main reducer, output gear, and lower roller gear, causing the lower roller to rotate. By relying on friction, it drives the sheet to feed and complete the rolling work.

4. Balance device:The balancing device consists of two tension rods and a balancing beam.

After the side frame is overturned, the balancing device presses down on the tail of the upper roller to maintain its balance.

5.Chassis: welded from channel steel and steel plate,Used for installing various components.

6. Electrical part:The electrical control system consists of an electrical control cabinet, an operation console, and a handheld button box.
