Symmetrical 3 Roller Bending Machine

Description:

The upper roller of the symmetrical 3 roller bending machine is vertically lifted and moved in the central symmetrical position of the two lower rollers, and is obtained by the screw worm drive of the screw, and the two lower rollers are rotated, and the output gear of the reducer meshes with the lower roller teeth for rolling. The plate provides torque.

The structure of the symmetrical 3 roller bending machine is a three-roller symmetrical type.

The upper roller is vertically lifted and moved in the central symmetrical position of the two lower rollers.

The hydraulic oil in the hydraulic cylinder acts on the piston to obtain hydraulic lift; the two lower rollers rotate and accelerate.

The output gear of the machine meshes with the lower roller teeth to provide torque for the rolled sheet.

Compared with the mechanical symmetrical 3 roller bending machine, the machine is fast and efficient.

Feature:

It is used to roll the sheet into a cylindrical shape, a circular arc shape and a conical shape under normal temperature conditions.

Superior performance, compact structure and easy operation. The upper roller lifting and lowering device is hydraulically driven.

The main drive is transmitted by the motor through the V-belt, and the reducer drives the two lower rollers to drive, and the rolling is flexible.

It adopts PLC programmable display control, the upper roller lift adopts displacement sensor detection, and the measurement digital display shows. Improve product efficiency and product quality, and the overturning frame is hydraulically tipped over.

       This type of bending machine is more efficient than the mechanical bending machine. The disadvantage is that the remaining head of the coil needs to be rounded or pre-bent by other equipment.

Structure:

This Symmetrical 3 Roller Bending Machine is symmetrical rolling machine, down up roller and then let up and down

Rollers do opposite roll to bend steel plate.

Symmetrical 3 Roller Bending Machine

This machine composed of two parts those are working part welded in whole chassis and moving part. Working part composed of left and right bearing base, one up roller, two bottom rollers (the material of the three rollers is 45#steel and do heat treatment), lifting screw and turbine and other accessory parts. Down rollers drive up roller to move, up roller can do up and down move by height way. Drive part composed of main motor, main speed reducer and other accessory parts.

Principle:

Bottom rollers were drove by main motor through main speed reducer, output spindle of main speed reducer driven to two down rollers by one group gears, the revolve direction of rollers adjusted by main motor.

Upper roll lifted by accessory motor through vice speed reducer drive worm and worm wheel mechanism of right/left rolls bearing base. That to let the lifting pole do up and down move. Unloading device is designed to remove the workpiece after drums bended into shape. Before unloading the upper rolls move to up limit position, the balance device on upper rolls ends hit upper rolls, draw out the spindle of the pin, then to remove the workpiece.
