Four Rollers Steel Plate Rolling Machine

3 roller hydraulic metal ring bending machine, metal sheet round bending machine, roller shutter cold roll forming machine
Summarize:
This machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical. Top roll can do vertical and level motion, up and down, parallel translation is display.
Feature:
The upper roller can move vertically as well as horizontally .
The end pre-bending is finished with high precision by moving the upper roller and making it unsymmetrical position with two lower rollers.
lower rollers are driven by the motor and decelerator for rolling the plate.
It is convenient and safe for feeding and operating because of the constant altitude of the lower rolls.

It is controlled by PLC, and the positioning of the rolls is digital readout.
The upper roller is in the shape of drum, accompany of the support rolls of two lower rollers for up and down adjustment, it can get the high precision for deviation from straightness of the finished products.

It adopts the rear rolling to gain the high precision for the circularity of the finished products.
The feeding direction and the moving direction of the top roll are opposite.

The end pre-bending is accomplished by the direct pressure from the upper roller so as to avoid the “angle of relief” of bending, at the same time; it can control the length and shape of the flat end.
This kind of Plate Rolls Bending Machine also can roll cone shape which is optional.
