Top Features of 3-Roller CNC Universal Plate Rolling Machine

The upper-roll universal three-roller plate bending machine is a general equipment for bending metal sheets into cylindrical, arc or other shapes. Almost all steel materials are formed into a cylindrical shape, and they are almost all rolled by a plate bending machine. The rolling machine equipment is widely used in boiler, shipbuilding, petroleum, woodworking, metal structure and other machinery manufacturing industries.

The specific structure of the upper-roll universal three-roller bending machine is explained as follows:

(1) Upper roller device

The upper roller device is mainly composed of the main oil cylinder, the upper roller bearing seat, the upper roller, and double-row self-aligning bearings. The upper roll is an important part of the plate rolling machine. The journals at both ends of the upper roll adopt extra-wide double-row spherical roller series rolling bearings. Due to the use of spherical roller bearings, it is beneficial to tilt the main roll and facilitate taper winding. The two main oil cylinders provide the pressure required to roll the plate.

(2) Horizontal moving device

The horizontal moving device is powered by the moving motor, and the upper roller device is driven to move horizontally through the reducer, worm gear, and screw nut mechanism to realize the asymmetrical rolling of the plate.

(3) Lower roller device

The lower roller device is composed of lower roller, lower roller bearing seat, input gear, sliding bearing and so on. The lower roller is an important part of the plate rolling machine, it is suitable for normal temperature conditions and low-speed heavy-duty places.

(4) Roller device

The supporting roller device is composed of supporting roller, inclined wedge mechanism, supporting roller adjusting hand wheel, etc. There are a set of rollers, which can be adjusted up and down according to the load size of the rolled sheet specification.

(5) Main transmission device

It is composed of main motor, electro-hydraulic push rod brake, cylindrical gear reducer and output gear.

(6) Tipping device

The tipping device consists of a ram, a tipping cylinder, etc. Installed on one side of the overturned frame, used for the overturning and recovery of the overturned frame. The overturning of the overturning device facilitates the removal of the product along the axial direction of the roller.
