Performance and characteristics of mechanical three roll symmetrical plate rolling machine:

The structure of this machine tool is a three roll symmetrical type, where the upper roll moves vertically in a symmetrical position between the two lower rolls through mechanical transmission; The two lower rollers rotate, and the output gear of the reducer is engaged with the lower roller gear to provide torque for the rolled sheet. This machine has a compact structure and is easy to operate and maintain.

Purpose and Scope of Application

This machine is a three roll symmetrical and upward regulating plate rolling equipment, mainly used for bending metal plates into cylindrical tubes of various diameters during cold working processes. It is widely used in mechanical industries such as boilers, chemicals, mines, construction, and shipbuilding.

Technical Parameter

Main structure and working principle

This machine is an upward adjustment symmetrical bending machine, which completes the rolling of cylindrical workpieces through the downward pressure of the upper roller and the rolling of the upper and lower rollers.

This machine consists of two main parts: the working part and the transmission part, which are welded onto the overall chassis. The working part consists of left and right roller bearing seats, an upper roller, two lower rollers (all three rollers are made of 45 # forged round material, quenched and tempered, and medium frequency heat treated), lifting screw worm gear pairs, 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 a main motor, a main reducer, and other auxiliary components.

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 direction of roller rotation is obtained by reversing the direction of the main motor.

The implementation of the up and down movement of the upper roller is achieved by the auxiliary motor driving the worm and worm gear mechanisms under the left and right roller bearing seats through the auxiliary reducer, causing the screw fixed on the worm gear to rotate and thus the lifting screw to move up and down. The lifting transmission device is made of copper worm gear and copper nut.

The unloading device is designed to remove the workpiece after the cylindrical part is rolled. Before unloading, the upper roller should be lifted into place, and a balance rod should be used to hold the upper roller at the end of the upper roller. Then, the pin shaft on the tilting bearing seat should be pulled out, and the tilting bearing seat should be overturned. The rolled workpiece can be released from one end of the upper roller.
