2. Description:
The structure of this machine is designed as hydraulic symmetrical up-adjusting 3-roller rolling machine. This rolling equipment with ultra width is developed for shell shaping of tank car by our company. The upper roller can move up and down vertically, the displacement is shown in digital. The two ends of upper roller are controlled by PLC, auto leveling, and can realize up and down synchronously under the condition of parallel (or incline). The upper roller is main drive, the lower is auxiliary drive. No slipping when plate rolling. This machine can roll arc or drum work-piece. With the help of auxiliary equipment, it also can roll cone work-piece in a certain range. It is ideal equipment for shell shaping of tank car.
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.
