W12NC-12x2500 4 roll plate bending machine

Description:

plate bending machine
W12NC-12x2500 4 plate bending machine

W12NC-12x2500 4 roll plate bending machine automatic steel roller bending machine(with pre-bending function), can rolling into round, cone and other shapes. Four roller machine is recognized as the fastest, most accurate, operation most easy of the series roller machine.

The hydraulic four roller plate rolling machine is also known as four roller hydraulic plate bending machine. It is specially used for rolling wide, small diameter and thick plates. Both the upper roll and lower roll are equipped with support system for reducing the deformation of the rollers. The main structure of the rolling equipment includes upper roll, lower roll, side roller, downturn system, left and right side frames, chassis, balance system, hydraulic system and electrical control system. The four roller hydraulic plate bending machine is of high technology, multifunction, high precision and convenient operation.

Features:

Totally European design, streamlined looking, frames of our machines are fabricated, welded steel (ST-52). Roll shafts, materials and bearings used in production are European quality. Also the torque limit of the machines is very high. CNC playback and CNC graphic control systems are available as optional accessory.

The main structure of the equipment includes upper roller, lower roller and horizontal movement mechanism, supporting mechanism,main drive mechanism,downturn system, left and right machine frame, chassis and balance mechanism, hydraulic and electrical control systems.

The model MH has both the upper and the lower roll powered with hydraulic motor and planetary gear box.

High precision pre-bending, freely setup the width of plate. Upper roller presses the plate end for pre-bending.

Upper roller likes drum with collaboration of carrier roller permit continual bending of any thickness of plate.

Safe work, fixed two down roller, upper roller does horizontal and vertical movement, and the plate don’t move during upper roller moving.

Unitary structure, convenient to move the whole machine as machine has a hardy under pan. No need to anchor bolt.

Different use has different control way, like top numerical control and below numerical control.Through exclusive technology, JOBEST can develop cones as easily as competitive machines can develop cylinders. And it eliminates scarring on the surface of shell or roll and also eliminates, in most cases, the need for grinding the lamination (bullnosing) on the minor diameter edge.
