technical field

The invention relates to the field of mechanical equipment, in particular to a plate rolling machine.

Background technique

The plate rolling machine is also called a rounding machine or a roller bed. It is the main equipment for making a cylindrical or arc-shaped workpiece by passing the plate through a rotating shaft and roller. According to the arrangement position of the shaft rolls, the plate rolling machine can be divided into three structural forms: symmetrical three-roll plate rolling machine, asymmetrical three-roll plate rolling machine, and four-roll plate rolling machine; the symmetrical three-roll plate rolling machine has a simple structure , easy to operate, low cost and widely used. The axes of the three shaft rollers of the symmetrical three-roller plate bending machine are arranged in an isosceles triangle. Its two lower rollers are synchronously active, so the position is fixed. The upper shaft roller is driven to rotate and can be used vertically. One end of the upper roller is movably connected with the bracket for the lifting movement in the direction. Usually, the factory building where the large plate rolling machine is placed is set up with upper and lower floors, and the upper and lower floors are connected in the middle. The bottom of the plate rolling machine is placed on the lower floor, and the upper roller, lower roller, and side rollers are exposed to the upper floor. One end is detached, and the processed roller is manually removed from the upper roller, and then transported to the designated place, which is very inconvenient, greatly increases the labor intensity and reduces work efficiency.
