This roller machines is the 3-roller machanical symmetrical rolling machine for rolling plates into cyliners.Upper roller can travel in vertical direction.The lower rollers are driven through the motor and speed reducing motor.The height of lower rollers is fixed, it is convenient for feeding plates.
This machine is widely used in the fields of boilers, ship manufacturering,petrols and so on.
This arc adjust plate rolling machine have a good function of pre-bending.Once feed the plate,the pre-bending of the edge and circle can be complete without turn around.The 3 rollers of this machine are all main drive shaft.The upper roller fixed,the down roller make the elevation movement along the arc.The main roller's rotation and lift movement used hydraulic transmission and the lift displacement display in screen.The mobile independent console make the usage more convenient.The safety device make the operation safer.This is a simple machine,easy maintenance, high bending precision straight edge, it is an advanced sheet metal bending equipment.
Structures
a. major elements
1. rollers:the most important part of the 3 roller bending machine machine , it is made of carbon steel.
2. frame:there are two frames in both sides, the bottom is fixed on the seat by nuts and they are connected through a connecting shaft to keep in the right position. The guide screw connects the worm wheel and the actions of upper roller is driven by this part.
3. gear box: ZSY/BW/WDH standard types are adopted.
4. balance elemetn:it is in the major speed reducer side, it is used to keep the balance of upper roller when unloadeing the plate.
5. underpan:it is made up of channel steel and plate, frames, gear box, motors and so on are all fixed on it.
6. Electrics:it is made up of operation box and motors.
b. Transimission Element
1. Major transmission: bottom rollers are the major ones, they are driven by the speed reducer and gear box.
2. Assitant transmission:the movement of upper roller is driven by the assitant ncavo-convex clutch is fixed on the transmission shaft. It is used to adjust the parallel degree between upper and bottom rollers
The shaft of up and down install in the frame,the bears on both sides used the spherical roller bearing.The main shaft is fixed.
The two down rollers aligning by the spherical roller bearing, fixed in the mobile rack which can do the arc movement along the central axis.And by the both sides of the roller lift cylinder to drive its arc movement.
The upper roller and two down rollers are all main drive roller.Through the hydraulic motor ,gears,chain to drive the main axis and side axis to do the movement of rotary.The unique synchronization mechanism to make the up and down roller have the same line speed when roll the different material plate.
The brake device for the rotary to ensure the accurate position of the workpiece bending volume and pre-bending.The whole machine has the sufficient strength and stiffness,the main parts of the force use the keys and pins toconnect,easy to installation and maintenance.
