Types of rolling machine,types of plate rolling machine

Plate rolling machine is an common machine in sheet metal fabrication workshop.It can bend steel plate into cylinder,curve,conical and so on.

According to the number of rollers ,we can divide plate bending rolling machine to 3 types.

1. 2 rolls plate roll machine

This machine is hydraulic drive.It consists of two rollers.Top roller is of steel and low roller is of urethane material.It can bend plate into cylinder one time stroke.It doesn't need pre-bending.And work very fast.

It is suitable for thin plate to bend small diameter.The diameter range is from 100mm to 600mm.It needs to change mould on the top rollers.It is suitable for mass production of same size cylinders.

2. Three rollers plate rolling machine

3 roller rolling machine has two types.One is hydraulic type ,one is mechanical type.

2.1 hydraulic upper roller universal plate rolling machine

The hydraulic rolling machine is a special equipment.The Top roller move by vertical by hydraulic oil tank.It puts pressure on the plate to make plate bending deformation.The top roller can also move by horizontal,power is electric motor.It is for adjust the horizontal distance between the top and bottom roller to make the top and bottom roller position in asymmetrical to pre-bend the sheet edge and decline the length of the flat zone. The bottom roller rotate  by electric motor,It supplies torque for bending plate.It has dropping device for taking out work-piece.

The dropping out device is driven by hydraulic cylinder.

2.2 Mechanical symmectrical 3 rollers rolling machine

The 3 roll plate rolling machine is fully mechanical type. The two lower rolls of the machine are driving rolls and are rotated by mechanical transmission of the motor and the reducer. The upper roll is a driven roll and rises and falls through mechanical transmission that is implemented by the motor, the reducer, a worm and a gear.

2.3 W11F Series 3-roller asymmetrical plate rolling machine

The structure style of this machine is 3 roller asymmetrical .Top roller and bottom roller are all main drive roller.The bottom roller lifts up and down to clamp the plate tight.Through the meshing between top roller gear and bottom roller to drive the top roller.The side roller move titling tpo pre-bend the plate and  circle.It is compact and easy operate and maintain . 

The range length of w11f plate rolling machine is from 1000mm to 2500mm.

The range of valid thickness is from 2 to 6mm.

This machine his user-friendly design and convenient operation. 

It is always equipped with asymmetrical solid rolls and easy initial pinch.

It has the function of prebending.

It’s very suitable for thin plate.

3.CNC hydraulic 4-rollers plate bending machine.

The machine is full hydraulic types.It belongs to four roller plate rolling machine.It is widely used in the manufacture of pressure vessels,machinery,hydro power,construction and other industries of the barrel body pre-bending ,roll round and also have a function  of checking circle and leveling.

The top roller is driven by hydraulic motor.Through the friction between the metal plate and the top roller to drive the bottom roller and side rollers rotate.And supply the torque for bending plate.The bottom roller,side roller and drop end are all driven by hydraulic oil tank.The bottom roller move up and down,the side roller move along with an arc.The bottom roller rise to clamp the plate and the side roller title up to the pre-bend the end of the plate.

 4.Sheet Metal Cone Rolling Machine 

The sheet metal cone rolling machine has 3 rollers.There is a hydraulic station.The hydraulic station is for upper roller  going up and down.

The up roller has front and back ends.The front and back can go down together.It can also go down seperately.Like front end goes down or

back end goes down.The upper roller goes down for clamp the plate.The 3 rollers rotate is drivened by electric motors.It can rotate closewise or anti clockwise.

This machine is for bending cone plate.It can produce mass sheet metal cone.
