W11-16*3200 three roller bending machine/rolling seam welding machine/steel wire bending machine

W11 Introduction

The machine adopts the four-roller structure with the upper roller as the main drive,providing the plates bending with torque through the engagement between the gear of the moderator and the gear of the upper roller. The lower roller makes vertial movements and imposes a force on the piston through the hydraulic oil in the hydraulic cylinder so as to clamp the plate tight. Side rollers are arranged on the two sides of the lides of the lower roller,and make inclining movement along the guide rail, and provide drive through the screw,the nut,the worm and the lead screw. The advantage of the machine is that the preliminary bending and rolling of the top ends of the plates can be conducted on the same machine.

Funcation of the machine

Three roller symmetric sheet rolling machine mainly worked for metal plate bending correcting and forming.

 It can bend plate to various specifications of cylinder, arc, and the machine has cone bending device, could bend cone work piece easily.

This machine is symmetrical three roller bending machine, top roller up and down was driven by mechanical transmission, two lower rollers are bending driving roller. The unloading bearing body was reversed manually. 

Top roller was lift up and down by turbine and worm at machine two ends racks bottom, ensuring stability during bending process. 

Both ends racks are main body of machine; adopt welding structure, eliminating internal stress treatment after welding. 

Both racks were installed at whole welding base. 

Main transmission system in machine tail and both racks constitute the complete machine 

The movements of machine were centralized controlled by electric appliances, operated on operation table.

This machine has the advantages of compact structure, simple technology, and reducing labor intensity.  

The speed of bending plate of main transmission part is 5.5m/min, controlled by gearbox and brake through electric motor.
